Embodiment Construction

[0039] The specific implementation manner of the present invention will be described in more detail below with reference to schematic diagrams. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0040] Such as figure 1 As shown, the present invention provides a method for constructing underground space with prefabricated roof, including:

[0041] Such as Figure 2-4 As shown, the originating shaft 7 and the receiving shaft 8 are constructed on both sides of the proposed underground space 2, and the proposed underground space 2 is divided into a plurality of channels arranged at intervals, so that each channel runs along the originating shaft 7 to the receiving shaft. The direction of the well 8 is set...

Abstract

The invention provides a top-plate-prefabricated underground space underground excavation building method, which comprises the following steps of: constructing a launching shaft and a receiving shaft at the two sides of an underground space to be built; dividing the underground space into a plurality of passages in separated arrangement, so that each passage is in communicated arrangement in a direction from the launching shaft to the receiving shaft; installing pipe joints into each passage by a pipe jacking method; installing an embedded grouting pipe communicated in a direction from the bottom wall to the side wall of a prefabricated top plate in a prefabricated top plate of each pipe joint; injecting waterproof paint to connecting seam points of adjacent passages through the embedded grouting pipe; removing adjacent side plates of the pipe joint at the adjacent passages and soil bodies between the adjacent side plates; connecting the prefabricated top plate of the pipe joint in positions of the adjacent passages through a metal plate; installing support units for supporting the pipe joints in the each passage; and casting reinforced concrete in positions of the bottom plate and the side plates of the pipe joints. The top-plate-prefabricated underground space underground excavation building method provided by the invention has the advantages that the construction cost is reduced; the construction quality is ensured; the construction method is simple; and the construction work efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of underground space development and construction, and mainly relates to a roof prefabricated underground space excavation construction method. Background technique [0002] With the rapid development of urban construction in our country, urban land resources are increasingly scarce. In order to improve the utilization rate of urban land resources, realize the multiple use of land, and promote the sustainable development of the city, the three-dimensional development of underground space under existing facilities such as urban green spaces, squares, roads, and pipelines has become a demand for urban construction and development trend. In order to reduce the impact on the existing facilities on the ground, it is increasingly necessary to use the underground excavation method. The underground excavation construction method refers to the direct excavation inside the foundation soil in urban construction projec...
