Xincheng Jiayuan precast residential project undertaken by Beijing Construction Company of China Railway Electrification Bureau is an important livelihood project in Jiangning District, Nanjing.

During the construction, the project department will take BIM Technology and precast building application research as the main direction, and carry out integrated design of buildings, structures and electromechanical devices, so as to realize the unified combination and optimization of pipeline embedment and PC component prefabrication in installation engineering, and improve production efficiency and product quality.

The builder’s home project in xiong’an new area is a centralized place that actively responds to the call of Hebei provincial Party committee and government to do a good job in the service guarantee for the construction personnel in the new area, and provides temporary office, housing, living services, education and training, basic medical treatment, first aid and other comprehensive service guarantee functions for the management and labor personnel of relevant units participating in Rongdong construction in accordance with the principle of “large dispersion and small concentration”.

Simply put, precast buildings put a lot of work in front of them and complete it in the factory.

Among them, the construction of large segment beam is a model for the development of cast beam..

1 camp project of the builder’s home in xiong’an new area, which is under the leadership of China Railway Construction Engineering Group and participated by China Railway assembly, covers a planned area of 120000 square meters, with a total construction area of 97000 square meters.

They are spliced as “building blocks” according to the design drawings.

Seven new construction methods, such as the construction method of precast building transfer floor and the construction method of precast building bolt I-steel cantilever scaffold, have been applied to effectively solve the technical problems of precast building construction.

The 8 residences have 24 floors, and the above 5 floors are precast and assembled integral shear wall structures.

The structural strength and service life can not only meet the building standards, but also greatly reduce the material waste, and realize the concept of good quality and green environmental protection.

The floor, stairs, walls and other components are like “building blocks”, which are precast and processed in advance by the factory and transported to the site.

Precast buildings mainly include precast concrete structures, steel structures, modern wood structure buildings, etc.

As a central construction enterprise, China Railway actively carried out research on modular design, installation process, component standardization, factory production technology and supporting equipment of precast buildings, formed complete sets of technical standards for design, production, installation and construction, and built a number of industry demonstration projects to contribute to the realization of the “double carbon” goal of China Railway Power precast houses.

In addition, the assembly type also greatly reduces the on-site wet operation and the discharge of dust, waste gas and wastewater, and avoids many hidden dangers of safety, quality and environmental protection from the source.

Compared with the traditional cast-in-place structure building, the on-site construction period is greatly shortened and the efficiency is high.

with standardized design, industrialized production, precast construction, information management and intelligent application, they have the advantages of saving resources, saving energy and environmental protection, shortening construction period and so on.

The new hospital phase II project of Haikou Fourth People’s Hospital undertaken by Guangdong company of China Railway Third Bureau is the first large-scale precast hospital project of the Bureau.

The Construction Industry Association of Panyu District, Guangzhou, and colleagues have come to the project for observation and exchange.

The building is equipped with water, electricity, heating, communication and various supporting services for living needs, which can accommodate 8000 people and realize one-stop service without leaving the park.

The main structural floor of the project is made of precast laminated slabs, and some internal walls are made of autoclaved lightweight ALC (autoclaved lightweight concrete slab) wallboard components, with an assembly rate of 50%.

The project department actively carried out professional technical training, and the PC component team members won the second place in the “Yangcheng construction craftsman Cup” precast concrete component assembly (component assembler) and the silver medal in the precast construction concrete component assembly project.

For precast bridges, China Railway Bridge Bureau took the lead in putting forward the method of “transforming water construction into land construction, and transforming single construction into factory construction”, and developed a large number of bridge precast products and related equipment, which have been widely used.

All the buildings of the project are built in the way of assembly, and more than 90% of the assembly components are manufactured by the intelligent cloud factory assembled by China Railway.

The Taifeng qianwanhui project of China Railway Erju Shenzhen Co., Ltd.

They are the representatives of modern industrialized production methods.

At present, the precast building construction of the project is advancing in an orderly manner.

After the precast components and accessories are delivered to the construction site one by one, the workers only need to assemble them like building blocks and fix them firmly.

The project has won the honors of “Jiangsu Construction Standardization star construction site” and “Nanjing high quality structural engineering”.

In the field of infrastructure construction, precast buildings have been vigorously promoted by the state because of their advantages of low carbon, environmental protection, resource conservation and so on.

What is precast construction? Precast building refers to a building that transfers a large number of on-site operations in the traditional construction method to the factory, processes and manufactures building components and accessories (such as floors, wallboards, stairs, balconies, etc.) in the factory, transports them to the construction site, and assembles and installs them on the site through reliable connection.

The theme of this year is “green, low carbon, energy conservation first”.

6 engineering group, has applied 19960 precast components of various types, with a prefabrication rate of 40% and an assembly rate of 51%.

The maximum number of workers for a single building is no more than 50.

June 13-19 is the 32nd national energy conservation publicity week.

The project adopts BIM Technology to realize the coordinated development of physical buildings and digital buildings, and help improve the efficiency of the overall operation and management of the project.

The Northwest wangyongliangjiayuan project in Haidian District, Beijing, undertaken by the construction and installation company of China Railway No.

actively promoted aluminum formwork, climbing frame For the integrated application of precast components, the project team conducted in-depth research on the production, transportation and hoisting of precast components, and greatly improved the construction efficiency of the project’s precast buildings through a series of measures such as preliminary investigation, scheme optimization, component acceptance and process learning.

The project department has specially set up a precast building innovation studio to vigorously carry out scientific and technological innovation and research activities.

Compared with traditional construction, it takes only 6 days to assemble a one storey building, and only 5 months to complete a building.
