Technical Field
The utility model belongs to the technical field of the underground pipe gallery construction, especially a can eliminate pipe gallery underground structure of foundation ditch bias voltage.
Background
The construction site of deep foundation pits such as urban rail transit stations, underground comprehensive pipe gallery process wells and house buildings is limited by site conditions, rivers, lakes, free faces and the like often exist on one side of the deep foundation pits, and in the excavation process, due to the fact that soil pressures on two sides are inconsistent, the deep foundation pits are inclined integrally towards one sides close to the rivers, the lakes and the free faces, and the safety and later-period operation of the structure are seriously endangered. Aiming at the problems, the design solution is to increase the depth and the thickness of the building envelope and increase the density of the foundation pit support. The above solutions do not fundamentally solve the problem.

In this embodiment, there are two lines for micro steel pipe bored concrete pile 1, two lines the top of micro steel pipe bored concrete pile 1 is equipped with one micro steel pipe bored concrete pile crown beam 3. The support system comprises upper concrete supports 8 connected with the fender post crown beams and middle steel supports and ground beams 9 connected with the fender posts.
The construction steps of the supporting structure are as follows:
1) two rows of miniature steel pipe cast-in-place piles 1 are constructed on the outer side of the fender post 2 on the side with smaller soil pressure on the outer side of the foundation pit,
2) constructing a crown beam 3 of the micro steel pipe cast-in-place pile;
3) constructing a fender post 2 at the side with smaller soil pressure outside the foundation pit;
