Description

TECHNICAL FIELD

[0001] The utility model relates to underground engineering technical field, especially point to a kind of prefabricated component assembly system for underground engineering construction. BACKGROUND

[0002] The construction of underground engineering is mostly carried out in built-up areas, and the underground excavation technology has a long construction period, high cost and is generally suitable for deep overburden conditions. In the case of shallow overburden, open excavation method is mostly used for construction, which has a greater impact on road traffic and living environment. Therefore, how to quickly restore road traffic and ground environment becomes an important factor for consideration in the construction plan. When building underground buildings in busy urban areas, roads are often occupied, affecting traffic. When the underground building is located on a main road and the traffic cannot be interrupted for a long time and needs to ensure a certain traffic flow, cover excavation method can be selected. Cover excavation method has a small operating space, so the construction speed is slower than open excavation method, and the maintenance and forming period of cast-in-place structure is long. If prefabricated components are used, the main structure is assembled on site at one time. The application of this technology can reduce noise disturbance, reduce environmental impact, improve construction efficiency, save labor, improve construction conditions and improve safety and quality.

However, the trolley structure is complex, the design and production cost is high, and the assembly time is long, which undoubtedly increases the project cost and construction period. Application No. 202121680821.6 provides a trolley top plate assembly mechanism that can cross steel support and assemble subway stations, which needs to rely on the trolley to realize the assembly function, and can only assemble the station top plate, and the function is not comprehensive.
