Embodiment 1

[0034] This embodiment provides an underground garage system that adopts permanent support to increase the usable area, such as Figure 1-Figure 3 As shown, it includes soil-squeezing piles 2, ground connecting walls 3, and column nets 4. Soil-squeezing piles 2 are arranged at intervals along the ground red line 1, and ground connecting walls 3 are set between adjacent soil-squeezing piles 2, and underground garages are arranged inside the land red line 1. Column grid 4.

[0035] Further, the soil-squeezing piles 2 are embedded with steel plates or reserved steel bar joints in advance during prefabrication, and the distance between adjacent soil-squeezing piles 2 is determined according to the size of the designed garage column network 4, so as to facilitate connection with the underground garage column network 4. Extrusion reduces the volume of the soil around the foundation pit, increases the density, increases the effective stress of the soil, and strengthens the embedding ...

Embodiment 2

[0039] This embodiment provides a construction method for an underground garage system that uses permanent support to increase the usable area. The edge of the land red line 1 is used as the design position of the underground garage, and the column network 4 is constructed according to the design position, and the column network 4 is connected to the ground. The wall 3 is connected; wherein, before the excavation of the soil, the ground red line 1 is used to construct the soil squeezing pile 2; afterward, the ground connection wall 3 is constructed in sections, and the ground connection wall 3 is used as the outer wall of the underground garage; the ground connection wall 3, The soil squeezing pile 2 and the column network 4 form a stable whole.

[0040] Specifically, the following steps are included:

[0041] (1) Design the location of the underground garage:

[0042] In the design stage of the underground garage, the specific location of the underground garage is determined...

Abstract

The invention discloses an underground garage system and method for increasing the usable area by adopting permanent support, and belongs to the technical field of underground garage construction. According to the technical scheme, the underground garage system comprises soil extruding piles arranged at intervals along a ground red line, wherein ground connecting walls are arranged between the adjacent soil extruding piles; and column nets of an underground garage are arranged in the ground red line, and the column nets and the ground connecting walls are connected to form the underground garage system with permanent support. According to the underground garage system and method for increasing the usable area by adopting permanent support, underground parking spaces can be arranged along the ground red line, and the usable area of the underground garage is increased; and the ground connecting walls and the soil extruding piles play a role all the time from construction completion to putting the whole underground garage into use, and permanent support is achieved.

Description

technical field [0001] The invention relates to the technical field of underground garage construction, in particular to an underground garage system and method that adopts permanent support to increase the usable area. Background technique [0002] With the acceleration of urbanization and the rapid growth of the number of private cars, the parking pressure of underground garages is increasing day by day, the contradiction between supply and demand of parking space is becoming more and more prominent, and the problems of parking space waste and low utilization rate are becoming more and more prominent. [0003] At present, the underground garage has the following problems: [0004] (1) Due to the limitations of its inherent functions, the existing garage has been unable to find more space for parking spaces. There is only a part of space between the red line of the building and the outer wall of the basement. In the design of the underground garage, the entire Most of the ...
