The user can hold down the left mouse button and drag the "adjust time" button left and right to review the construction process.

The left panel of HT displays project information in a loop, including construction time and investment plan, construction personnel safety, project management goals, excellence goals, and technology research and development goals.

The scene supports 3D all-round roaming, displaying equipment operation, construction scenes at various stages, personnel information, etc., and construction information can be viewed according to needs, which is convenient for viewers to view comprehensive construction index data comprehensively and intuitively through the large visual display screen.

System Analysis

Combined with BIM 3D modeling, the system adopts the self-developed HT for Web product to carry out digital twinning of the entire process of site leveling, foundation, backfilling and other working conditions, and realizes a Web 3D construction management visualization platform, so as to estimate the cost of construction projects , control the budget.

Link 3D models of buildings and construction sites with construction progress, and integrate with information such as construction resources, safety quality, and site layout. It integrates various systems such as construction progress, construction personnel wearing devices, and safety management to achieve visual expression. VR, handheld or fixed touch setting terminals can be supported, reducing the intermediate links of information transmission and ensuring the timeliness and timeliness of information transmission. nature, unified project standards.

Pile foundation construction process visualization

The pile foundation is composed of foundation piles and a cap connected to the top of the piles, and has the characteristics of good seismic resistance and small settlement. HT supports a variety of model renderings, and cooperates with 2D panels to monitor the construction progress of pile foundations in real time.

Field leveling and field

Before the start of construction, the site must be completed with three links and one leveling. Obstacles such as cables, pipelines, equipment foundations, etc. on the ground and underground should be removed. Various temporary facilities such as temporary electricity, temporary water, and safety equipment are ready to ensure that the construction site is level.

HT visualization is integrated with the construction management system, assists in rationally arranging the positions of vertical transportation equipment such as tower cranes and construction elevators, planning the construction roads and sites, reducing transportation costs and secondary transportation in the site; installing information collection equipment in the corners of the site, including LAN controllers , satellite positioning receivers, etc., process data in real time through wireless communication, check key information through 3D views, organize basic requirements and principles, and propose reasonable site layout plans to ensure smooth construction and improve construction efficiency.

and

Bored pile is one of the basic structural forms of engineering structures. It has the advantages of high bearing capacity, high strength and rigidity, and small pile deformation. However, as a concealed project, it has problems such as difficult construction monitoring and low level of information management and control.

Based on Beidou positioning technology, contact instrument combination method and management cloud platform HT Cloud, the data collected from the mass concrete wireless temperature measurement system by temperature sensors, wireless temperature collectors, wireless repeaters and management software can be directly input In HT for Web GIS, it is used for automatic monitoring of temperature changes in the process of mass concrete pouring of high-rise buildings to ensure construction safety. Through the 3D effect, the intelligent management and control of pile position measurement, hole formation inspection, mud monitoring, concrete pouring and quality traceability in the construction of bored cast-in-place piles can be realized.

crane construction visualization

After all the pile foundation construction is completed, the tower crane can be arranged to enter the site. Tower cranes are inspected before and after installation and during daily use. Integrating the tower crane operation monitoring system, the operator can obtain the current operation parameters of the tower crane in real time and monitor the operation status of the tower crane.

With the 3D configuration effect, HT can alarm for dangerous operations such as tower crane collision, display the operation of tower crane cross operation, and ensure the safety of tower crane operation to the greatest extent.

Foundation pit enclosure beam construction

The enclosure beam is equivalent to the "backbone" of the project, which is crucial to the support and stability of the entire project. One is to protect the foundation pit, and the other is to protect the surrounding structures and other facilities from being affected by the construction. The traditional enclosure pile construction is carried out according to the drawings, the construction process cannot be observed, and the excavation and acceptance can not be carried out after the pile is formed.

With the support of HT technology, the system can restore the position and depth of each pile, and display it on a large visual screen. Through real-time monitoring, it can avoid problems in any part of the maintenance beam construction and affect the entire project. quality and progress, even causing huge economic losses and adverse social impacts to investors.

Earthwork excavation and roof beam

Earthwork excavation is the process of loosening, breaking, excavating and transporting soil and rocks, and is a key process in the initial stage of the project and even in the construction process. A roof beam is a layer of concrete beams pressed on top. The backfill soil shall not contain plants, bricks and other sundries. Due to the construction site, construction machinery, special construction technology and other reasons, manual compaction is generally adopted for earthwork backfilling to make up for the places where mechanical compaction is not available.

The system can independently set the warning type information according to the construction points, and use the 3D effect 1:1 high simulation to simulate the whole process of earthwork excavation, so as to avoid the uneven slope of the foundation pit, the uneven base and the accumulation of debris before backfilling, so as to realize the excavation along with the excavation. With the repair, speed up the construction technology operation speed and improve the engineering operation quality.

Topic Structural Construction Visualization

Podium structure construction

The podium generally refers to the lower part of the main body of a multi-high-rise building. The construction content includes the reinforcement of the main structure of the podium. The main reinforcement forms are enlarged section, outer steel, carbon fiber cloth, etc. Involving reinforcement and transformation, steel structure, fine decoration, strong and weak electricity, fire protection, curtain wall and other majors, there are many cases of multi-type cross-operation and three-dimensional operation.

The system is connected to the task management system of construction, and the feedback mechanism of manual reporting is replaced by digital drive. The HT visual large screen displays the construction plan start and completion time, construction theme, construction type, construction processing result, person in charge and construction unit and other information. Combined with 360-degree panoramic visualization and data linkage, it is possible to carry out overall planning and comprehensive organization and coordination according to the difficulties in project management, so as to ensure the smooth completion of indicators such as the quality and safety of the podium.

Building the main steel structure

The main structure is based on the foundation and foundation, accepting, bearing and transmitting all the upper loads of the construction project, and maintaining the organic connection of the integrity, stability and safety of the upper structure. The main structural system of the project is a steel frame-reinforced concrete core. cylinder. The use of outrigger trusses during the construction of the project greatly improves the overall synergistic bearing capacity of the structure and reduces the deformation difference under the action of vertical loads.

HT renders the stress-strain effect of the truss in each construction stage according to the characteristics of the outrigger truss with large dimensions and complex node structure. Arranging sensors at the most representative positions can obtain the pressure point information in the scene, so as to monitor the stress and strain of the outer frame and the core tube, instead of manually analyzing the influence of the settlement compression deformation difference on the internal force of the outrigger truss, the core The compression deformation data of the tube and the outer frame structure are controlled within the allowable range of the specification, to ensure the construction quality of the outrigger truss, and to determine the best time for stress release and welding of the weld butt joint.

Laminate construction

In order to make the floors stronger and safer, steel structures are generally used for floors when they are constructed. However, in the construction process, there are difficulties in the positioning of the floor slab edge, the large volume of the steel structure, and the construction of special-shaped components.

Based on UWB positioning base station, HT combines BIM technology to optimize the comprehensive layout of floor slabs through on-site lofting, and adopts 3D scene virtual roaming for the feasibility of floor slab positioning to achieve the effect of determining the location of the welding point for penetration welding of floor slabs and steel beams. Installation, to ensure a reasonable layout, to achieve zero demolition and modification, one-time excellence.

Visualization of masonry curtain wall installation process

Exterior wall structure and decoration construction

In terms of exterior wall construction, construction projects have adopted a combination of general contracting and professional engineering subcontracting for many years. Difficulties are often encountered in the construction of the project, which affects the quality of the project.

The system integrates the external wall vent and the external wall dry hanging surface layer node to deal with the ventilation and air conditioning system of the construction project. The connection nodes of the tuyere louvers and the protection methods of the air ducts in the curtain wall cavity are clearly described, so that the original fragmented video can be seen in a panoramic view in the real 3D scene. And from any required perspective, a panoramic grasp of the overall scene, including the main structure, exterior wall decoration, door and window installation, ventilation installation and other specialties, to achieve the target positioning required for accurate positioning. After the project is completed and put into use, rainwater leakage from external walls and external windows, water seepage from window sills, air leakage from the interface of ventilation openings, deformation of indoor suspended ceilings due to dampness and wind disturbance, and substandard thermal insulation, etc., will affect the function of use.

Curtain Wall Construction

The curtain wall is the outer wall of the building, it is not load-bearing and hangs like a curtain, so it is also called "curtain wall", which belongs to the building's enclosure structure. When using tools such as scaffolding, safety hazards are more likely to occur. The system is connected to the weather system data, and the weather data of the day can be predicted, monitored and analyzed in the field. When there are very few weather data, the project implementation plan can be adjusted to ensure the safe implementation of the project.

Indoor incision and base

Masonry engineering is a very important sub-project in construction engineering, which is very important to the service life and quality of the building. Traditional masonry projects have quality problems such as disordered material stacking, incomplete ash joints, concrete back sills, and masonry grooving. HT can freely set alarm types according to the construction situation, such as transportation quantity warning, blind seam, transparent seam warning, etc., which can guide the on-site construction more clearly and intuitively.

Hydropower, Elevator, Ministry Network

Enterprises can access the area electricity monitoring system according to the situation to monitor the electricity usage of daily electrical appliances in the living area of the construction site in real time, and realize real-time electricity parameter monitoring, electricity consumption statistics and over-limit alarms in dormitories, offices and other areas in the living area. and other functions. The sewage discharge treatment system realizes automatic sampling of enterprise wastewater and on-site sewage, online monitoring of flow and online monitoring of major pollution factors. The distribution of POI data of service facilities such as electricity and water in the park can be fully presented, ensuring that water pipes, power grids, and wind pipes do not conflict, and realizing real-time perception of displayed data.

By integrating the HT smart park energy management system, when the construction project is completed, centralized monitoring and management of building electricity, water, buildings, etc. can be carried out to reduce the daily energy consumption of the building and improve the management level of energy-saving work.

Landscape Environment

Greening is a very important element in the landscape environment, and good greening will give people a feeling of beauty and natural edification. Based on Geographic Information System (GIS), the system supports visual monitoring of various environmental monitoring points and elements such as plants, sculptures, and solid waste generated during construction, such as the type, quantity, and distribution location. Help to deal with the problems of unscientific plant matching and uncoordinated planting positions in traditional greening. Support the query of the detailed information of the target construction, and use the 2D configuration panel to display, such as material scheduling and site layout, wall removal, ground hardening, ground paving, greening maintenance and other information, assist users to fully grasp the quality of the landscape environment, and carry out environmental management for users Provide scientific decision-making basis.
