Problems solved by technology

[0005] Due to the advantages of high strength, light weight, good water resistance, long service life, high safety, low space requirements, remarkable environmental protection effect, simple construction and short construction period, steel sheet piles have become a commonly used support for underground garage construction. However, due to the characteristics of good toughness and poor rigidity, steel sheet piles are prone to bending when used as support piles, especially when the groundwater level is high and the fluidity of the soil is strong, which limits Areas where steel sheet piles are used

Embodiment 2

[0077] In this embodiment, the underground garage to be built has four floors of parking platforms, including three floors of intermediate parking platforms and one floor of bottom parking platforms, which are divided into two upper and lower construction sections, wherein the first construction section above includes two The parking platform in the middle of the first floor, the second construction section below includes a middle parking platform on the first floor and a floor parking platform, except that the second construction section lacks a middle parking platform on the first floor, and the specific construction steps are similar to those in Example 1. Please refer to Embodiment 1 for construction steps.

Embodiment 3

[0079] In this embodiment, the constructed underground garage has eight floors of parking platforms, including seven floors of intermediate parking platforms and one floor of bottom parking platforms, which are divided into three construction sections from top to bottom, which are called the first floor from top to bottom. A construction section, a second construction section and a third construction section, wherein the construction of the first construction section includes a two-story intermediate parking platform, the second construction section includes a three-story intermediate parking platform, and the third construction section includes The middle parking platform and the bottom parking platform on the second floor.

[0080] During construction, follow the steps below:

[0081] (1B) This step is the same as the step (1A) in the embodiment 1, please refer to the step (1A) in the embodiment 1 for the specific construction, and will not repeat it here.

Abstract

The invention provides a construction method for an underground garage. According to the method, an underground garage is at least divided into two construction sections from top to bottom. The method comprises the steps of: (1) performing construction of guard posts and stand columns and forming guard walls; (2) performing the construction of the first construction section: digging earth to finish the earth digging in the first construction section, stopping digging, building middle parking platforms of the underground garage, casting outer walls via pouring, and finishing a roof of the underground garage; (3) continuing earth digging and finishing the earth digging in the second construction section, building middle parking platforms and continuing pouring of outer walls, and connecting the outer walls of the two construction sections mutually; (4) repeating the step (3) and performing construction in each construction section until the pouring of the outer walls and the building of the middle parking platforms in all the construction sections are finished, wherein the guard walls and the outer walls form wall bodies of the underground garage together. The construction method can effectively increase the construction speed of an underground garage and improve the safety of an underground garage.

Description

technical field [0001] The invention belongs to the construction field of underground buildings, and in particular relates to a construction method for an underground garage. Background technique [0002] At present, the faster the speed of urban construction, the less and less land can be used on the ground. People are turning to the development of underground space, especially the development of underground three-dimensional garages. Development has been severely restricted. Due to the high density of urban ground buildings, it is impossible to use sloping excavation for the construction of underground garages. The support piles are first sunk to the ground to form the foundation pit enclosure structure, and then The excavation of earthwork in the enclosure structure has become the main method for building underground garages in urban areas. [0003] In areas with dense population or dense buildings on the ground, when constructing underground garages, the reverse method...
