中文The hub of the world, the tide rises in the east,
Recently, the attention-grabbing domestic
Shanghai East Railway Station comprehensive transportation hub construction project site,
7 sets of DMP construction method mixing pile equipment were assembled for the first time.
Hold your head high and be full of enthusiasm,
Along with the beating notes coming from the machine,
Lifting, sinking, drilling, stirring,
Laying the foundation for a world-class transportation hub.
Oriental Hub Shanghai East Railway Station is a large-scale comprehensive transportation hub relying on the Shanghai East Railway Station that integrates aviation, national railway, municipal railway, urban rail transit and other transportation functions as well as station city development. With a total investment of 150 billion yuan, it is a link between long-distance and long-distance transportation. A world-class transportation hub between the Triangle and the world. After completion, Shanghai East Railway Station will become the second largest railway passenger station in Shanghai after Shanghai Hongqiao Station. It is a major project to promote the construction of the Shanghai Free Trade Zone Lingang New Area and will accelerate the construction of Shanghai into a modern socialist international airport with world influence. Metropolises are of great significance.
The Oriental Hub Shanghai East Railway Station Underground Civil Engineering Project is located in Zhuqiao Town, Pudong New Area. The total construction area of this part of the project is approximately 374,600 square meters. The main construction content is the foundation pit, foundation and main structure of the underground engineering main structure engineering (including Mechanical and electrical pre-embedded, including: air-rail combined transport module, underground part of the urban atrium and corridor, underground parking lot and equipment room, passing through the municipal road (Zhandong Road, MRT reserved project including double-line shield tunnel 673 meters) , long-term related line reservation projects, air-rail logistics reservation projects.
In this project, DMP construction method mixing piles are mainly used for the station area, the junction of the station area and the station front channel, and the underground continuous wall groove wall reinforcement, passive zone reinforcement, and slope reinforcement in Hedong District. The project adopts the "socket-one-hole method" For construction, the total square meter of mixing piles required on site is about 370,000 square meters, with a pile diameter of 850mm and a depth of 16~25m. Among them, there are a total of 499 water-stop curtains in the station area, a total of 60 height difference reinforcements, and a total of 72 groove wall reinforcements. , 12,654 pieces of reinforcement inside the pit; a total of 565 pieces of groove wall reinforcement at the junction of the station area and the channel in front of the station; a total of 224 pieces of groove wall reinforcement with DMP mixing piles in Hedong District, and 484 pieces of in-pit reinforcement.
This construction project has a tight schedule and heavy construction tasks. The project brings together 7 DMP mixing pile equipment for construction in a row. They cooperate safely and efficiently on site, have low failure rates, are stable and accurate, and quickly adapt to the construction environment. Each unit completes 10 to 12 hours in 12 hours. The excellent construction performance and powerful product performance of the piles effectively ensure the construction efficiency of the project.
This project site uses DMP construction method mixing pile equipment. Judging from the on-site construction results, they have very good intelligent digital construction technology, have little disturbance to the surrounding environment, have high pile quality, and perfectly meet the construction needs. We can trust the quality of our products and feel confident when using them. "The person in charge of the on-site construction said.
The superiority of DMP mixing piles has been further verified and recognized in this "super project" of the Oriental Hub, which will help to promote and apply it in more domestic infrastructure projects in the future. DMP mixing pile equipment is also in this "super project". Project", with its strong product strength, excellent quality and market reputation, it has once again been highly praised by users.
The DMP construction method mixing pile equipment jointly developed by SEMW, Shanghai Yuanfeng and Tongji University uses a digital construction control system to control the rotation of the mixing blades, and four drill pipes to simultaneously spray slurry and gas to achieve automated pile construction. The equipment realizes micro-disturbance construction through automatic control of underground pressure and the pressure discharge channel formed on the outside when the special-shaped drill pipe rotates. It solves the problems of uneven pile strength, low level of informatization, difficult to control construction quality, and replacement of soil during the construction of traditional mixing piles. There are many problems such as large number of bodies, large construction disturbance, and low pile forming efficiency.
DMP construction method mixing pile equipment adopts an intelligent digital construction control system, which makes the quality of the construction process controllable and greatly improves the convenience of construction. The content collected and displayed by the digital construction control system includes shotcrete pressure, slurry flow, jet pressure, in-ground Pressure, pile forming depth, pile forming speed, pile forming verticality and other parameters; can generate a construction record table including pile length, construction time, underground pressure, cement dosage, pile forming verticality and other parameters; at the same time, the construction parameters can be uploaded to The centralized control center enables real-time monitoring of the construction process.
