Embodiment 1

[0030] Such as Figure 1-4 As shown, a push-push underground space group construction method is carried out according to the following steps:

[0031] (1) Select plots without deep foundations or pile foundations as work plots, such as roads, gardens, squares, etc.;

[0032] (2) Excavate rectangular pipe-jacking work wells on both sides of the work plot, and the rectangular pipe-jacking work wells include originating shaft 2 and receiving shaft 6;

[0033] (3) Rectangular pipe jacking wells shall be constructed according to the sequence of alternate hole jumping, that is, "interval hole jumping construction process". The odd sequence of rectangular pipe jacking wells shall be constructed first, and the even sequence of rectangular pipe jacking wells shall be constructed after the construction of odd sequence of rectangular pipe jacking wells is completed. In the pipe jacking working well, in the original soil layer 7, the pipe joints 3 are pushed from the originating shaft 2 ...

Embodiment 2

[0037] Such as Figure 1-4 As shown, a push-push underground space group construction method is carried out according to the following steps:

[0038] (1) Select plots without deep foundations or pile foundations as work plots, such as roads, gardens, squares, etc.;

[0039] (2) Excavate rectangular pipe-jacking work wells on both sides of the work plot, and the rectangular pipe-jacking work wells include originating shaft 2 and receiving shaft 6;

[0040] (3) Rectangular pipe jacking wells shall be constructed according to the sequence of alternate hole jumping, that is, "interval hole jumping construction process". The odd sequence of rectangular pipe jacking wells shall be constructed first, and the even sequence of rectangular pipe jacking wells shall be constructed after the construction of odd sequence of rectangular pipe jacking wells is completed. In the pipe jacking working well, in the original soil layer 7, the pipe joints 3 are pushed from the originating shaft 2 ...

Embodiment 3

[0044] Such as Figure 1-4 As shown, a push-push underground space group construction method is carried out according to the following steps:

[0045] (1) Select plots without deep foundations or pile foundations as work plots, such as roads, gardens, squares, etc.;

[0046] (2) Excavate rectangular pipe-jacking work wells on both sides of the work plot, and the rectangular pipe-jacking work wells include originating shaft 2 and receiving shaft 6;

[0047] (3) Rectangular pipe jacking wells shall be constructed according to the sequence of alternate hole jumping, that is, "interval hole jumping construction process". The even sequence of rectangular pipe jacking wells shall be constructed first, and the odd sequence of rectangular pipe jacking wells shall be constructed after the construction of the even sequence of rectangular pipe jacking wells is completed. In the pipe jacking working well, in the original soil layer 7, the pipe joints 3 are pushed from the originating sha...

Abstract

The invention belongs to the field of underground engineering construction, and particularly relates to an incremental launching type underground space group construction method and application. The method is characterized by comprising the following steps that 1, a deep foundation-free land mass, that is, a pile foundation-free land mass is selected as a working land mass; 2, rectangular pipe jacking work wells are excavated on the two sides of the land mass; 3, the rectangular pipe jacking work wells are constructed according to the alternate jump hole sequence, pipe sections are subjected to incremental launching in the direction from a launching well to a receiving well in an original soil layer to form pipe jacking tunnels, and when each pipe jacking tunnel is constructed, a ring of lengthened pipe section is constructed every other 10 m to 20 m for later-period hole punching; 4, a hole is punched in the lengthened pipe section between every two adjacent pipe jacking tunnels to enable the adjacent pipe jacking tunnels to be communicated with each other, and then multiple crisscross underground spaces are formed; 5, an underground space place is constructed. The method has the advantages that construction can be conducted in shallow covering soil, the temporary land area is small, traffic does not need to be cut off, the ground environment is not affected, and the influence of underground water on construction can be overcome.

Description

technical field [0001] The invention belongs to the field of underground engineering construction, and in particular relates to a construction method and application of a push-type underground space group. Background technique [0002] The 21st century is the era of underground space. Due to the process of urbanization, the rapid development of transportation and the rapid growth of population, the urban ground space is becoming more and more restricted. People have realized that only the development of underground space is the only feasible way to quickly alleviate the current predicament. Method. [0003] Usually, the method of building underground space is to build high-rise buildings and use deep foundation pits to pour 2-4 floors underground. First, it is needed for the foundation of high-rise buildings, and it is also used as underground space development for commercial or underground parking garages, etc., or ordinary cover-excavation methods. It is also necessary to...
