Embodiment Construction
[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0037] A method for constructing an underground space based on a circular shield and a pipe curtain is carried out according to the following steps:
[0038] see figure 1 , S1, construction shaft 1: use caisson method, shaft shield method or open cut method to construct two shafts 1 at opposite corners or on the same side of the underground space to the design depth.
[0039] see figure 2 , S2, construction of cross passage 2: construction of cross passage ...

The present invention proposes a construction method for underground space based on circular shield tunneling and pipe curtains. The steps are as follows: construct a vertical shaft, construct a cross passage at the lower part of the shaft, construct a U-shaped well below the cross passage, and construct a pipe between the U-shaped well and the cross passage. Curtain, construction guide hole in pipe curtain, construction of side piles, center column and cover plate, construction of main structure. The invention only needs two vertical shafts to realize the large excavation of the underground space. Except that the U-shaped shaft needs to be constructed by mechanized circular shield, various shafts, horizontal passages, pilot tunnels, pipe curtains, and main structures can be used. The construction method, so that it can be truly economical, reasonable, safe and efficient through the comparison and selection of various schemes; the circular shield can realize ultra-small radius turns, which enriches the structural form of the cross-section of the underground space. The starting end and receiving end of the pipe curtain, after the construction of the pipe curtain, can form a large underground space with good waterproof and stable ground, which is convenient for subsequent various forms of underground excavation construction.
Description
technical field [0001] The invention relates to the technical field of underground space construction, in particular to an underground space construction method based on a circular shield and a pipe curtain. Background technique [0002] At present, the most developed and utilized urban underground spaces are subways, civil air defense projects, underground parking lots, etc. Most of the underground spaces such as urban roads, public green areas, and old residential areas have not been utilized, and these areas are the areas with the most frequent residents' activities. . How to build an underground space “in front of your own home” to expand residents’ shopping, leisure, parking, etc., and minimize or avoid damage to existing buildings on the ground is a problem that designers need to pay attention to and solve. [0003] Japan has made many attempts in underground excavation methods, including the construction of subway tunnels and stations, the expansion of underground sp...
