The project department uses Internet+BIM technology to provide support for informatization construction.

No mistake^_^ It’s him – Zhonghai Ludan Mingyuan.

They are currently the highest precast residential buildings in China, and are constructed by Guangdong Company of China Construction Fifth Bureau.

（2） Refined construction quality.

The project department optimizes the construction plan, organizes an emergency special meeting overnight, and discusses with Party A, the designer, and the aluminum mold manufacturer.

The project department plans to apply for a national patent for this process.

On the one hand, the special working group has strengthened its study, consulted experts, and visited Hong Kong and other places to observe and learn.

The project department also decomposes the construction process to form independent flow construction of 8 and 9 buildings.

3、 In the preliminary technical planning of “innovation is hard to break, and new technology is condensed”, the project department has set up a PC project project research team and project implementation team.

(It’s really amazing!) The project department has solved one “roadblock” after another with its excellent professional level and indomitable spirit of innovation.

The small assembling construction is the use of precast components and accessories in the factory, and the mechanical assembly at the construction site to form a building, which is an important part of the construction industrialization.

In terms of organizational structure and staffing, the project department has added PC professional engineers; According to the actual situation of the site and the interpenetration of the installation process, two aluminum mold installation teams are arranged for parallel construction.

The demolition and reconstruction project of commercial housing led by Shenzhen Municipal Government is a popular project with a total construction area of 260000 square meters.

There are many difficulties in the process of precast construction.

The project adopts the new form of concrete+aluminum mold+PC.

The overall assembly of components shall be very tight, otherwise the accumulated error will cause the subsequent components to be unable to be hoisted in place or installed normally.

The project department uses BIM technology to simulate the whole process of animation video construction, check the internal collision of components and the collision between components and the pre-embedded parts on the construction site, ensure the installation efficiency and quality of components on the construction site, and establish a traceable information record of PC component installation and maintenance.

2、 “Scientific implementation of policies and establishment of resource network” (I) Pre-orientation of technology management.

From the determination of the form of the component, to the component splitting, the pre-embedding of the installation connector, the selection of the transportation route, and to the preparation before the lifting, the project department has considered in advance and controlled accurately.

Since August 12, 2015, the basement of the commercial podium has been flushed out of the plus or minus zero five days in advance on September 6, when the project site has not completed the office and living quarters; On September 18, the capping node of the commercial podium was completed 12 days in advance.

The Project Department weaves a “resource assembly network” according to the characteristics of precast construction.

The precast building has obvious advantages in functional characteristics, structural system, building performance and project cost.

The concrete products of building “components” are processed and produced in the factory, transported to the construction site, assembled in the building frame, and then welded with steel bars and poured with concrete to perfectly assemble the components and the building frame, Realize the “building blocks” type house building.

Up to now, the project department has installed 1610 individual precast components.

The cast components shall be produced at least half a month ahead of the project schedule to meet the site construction requirements.

Finally, it is decided that when the precast components are embedded, the wall-connecting parts are buried at the bottom of the beam, and the aluminum mold is optimized with reserved holes, which solves the problem that the wall-connecting parts of the external scaffold cannot be embedded.

From the production, transportation and hoisting of industrialized components, to the installation of reinforcement and formwork on site, electromechanical embedment and concrete pouring, each process is closely linked.

The control of hoisting quality is the key step and core content of assembling integral structural engineering, and the accuracy of construction survey is the key point of control.

Building 8 # and Building 9 # are precast construction, with the structural height of 147 meters and 124 meters respectively.

1、 “Plan a layout and explore a new way of construction” Zhonghai Ludan Mingyuan project is the first project in Shenzhen to use PC component columns.

At present, the 8 # building has been constructed to 24 floors.

The construction team went to the PC manufacturer several times to learn skills, and 1:1 simulated installation and drill on the spot.

At present, the factory has been built to 22 floors, 1360 pieces of components have been installed, and 1650 cubic meters of concrete have been hoisted.

For example, when the external scaffold is suspended, the traditional method is to embed the wall-connecting parts on the slab surface, but the wall-connecting parts cannot be fixed after the installation of PC components.

（3） The processes are interpenetrated and tightened.

In addition, the technical team of the project carried out no less than 20 thematic discussions and meetings, concentrated on reviewing professional drawings, put forward more than 100 optimization suggestions, and carried out optimization design with the owner and design institute; The construction scheme for aluminum formwork installation and the construction scheme for PC component installation have been prepared.

（4） Innovative construction process.

The largest single weight of small woven PC components is 7.45 tons, 4.566 meters long and 3.13 meters high, which brings great challenges to lifting equipment and construction.
