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...

The invention provides a roof prefabricated underground space underground excavation construction method, comprising: constructing an originating shaft and a receiving shaft on both sides of the proposed underground space, dividing the underground space into a plurality of passages arranged at intervals, so that each passage They are arranged through the direction from the originating well to the receiving well; the pipe joints are arranged in each channel by the pipe jacking method, and the prefabricated roof is provided in the prefabricated roof of the pipe joints from the bottom wall to the side wall of the prefabricated roof. Grouting pipe: inject water-stop paint at the joints of adjacent passages through pre-embedded grouting pipes, remove adjacent side plates of pipe joints at adjacent passages and the soil between adjacent side plates, and pass through metal plates Connect the prefabricated roof of the pipe joints at the adjacent passages, set the support unit for supporting the pipe joints in the passages; pour reinforced concrete at the bottom plate and side plates of the pipe joints. The invention provides a method for constructing an underground space with a prefabricated roof, which reduces the construction cost, ensures the construction quality, and has simple construction methods and fast construction efficiency.
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...
