Problems solved by technology

[0002] At present, the number of underground garages in cities in my country is relatively small, especially in large and medium-sized cities with high population density, but there are a large number of shallow basements in urban areas, especially in business districts and some residential areas. Some of these basements become underground shopping malls, and some become underground garages. Most of these basements have only one or two floors. The utilization of underground space is seriously insufficient. Some basements are built in the area between buildings on the ground. It is very difficult to build new underground garages in undeveloped plots. With the gradual increase of car ownership, the parking spaces in these existing above-ground and underground garages are seriously insufficient, which has gradually affected people's normal travel and improved underground space. Therefore, it has become necessary to transform some shallow basements into deep underground garages to solve the shortage of parking spaces. When constructing deep underground garages in these areas with shallow basements, how to carry out construction safely and efficiently, It has also become a problem that the industry needs to face

Embodiment 1

[0073] refer to Figure 1 to Figure 7 , in the present embodiment, adopt the construction method of adding a deep underground garage locally in the basement in the present invention to build a new underground garage in the area where the basement is built.

[0074] In this embodiment, the plot used to build the underground garage is a plot with a basement, and there is no ground building in the plot of the basement, and the underground garage is specifically constructed according to the following steps:

[0075] (1) Select a plot with a basement and no superstructure, determine the construction area, and determine the area occupied by the underground garage. refer to figure 1 , figure 1 Middle, axis ①~⑧ and axis is the axis of the existing basement, the axis and is the sinking position of the steel sheet pile, the axis with axis The intersection point 131 is the sinking position of the column pile, and the sinking position of the uplift pile is not shown in the fig...

Embodiment 2

[0113] In this embodiment, the basement in the construction area is a double-layer structure, and this embodiment is basically the same as Embodiment 1, the difference is that:

[0114] Before sinking the column piles, at first on the middle floor of the basement, offer the floor column pile holes up and down relative to the top plate column pile holes and the bottom plate column pile holes, then sink the column piles.

[0115] Before sinking the uplift piles, the floor uplift pile holes opposite to the top uplift pile holes and the bottom plate uplift pile holes are firstly opened on the middle floor of the basement, and then the uplift piles are sunk.

[0116] Before sinking the steel sheet piles, first set up the floor steel sheet pile grooves on the middle floor of the basement opposite to the roof steel sheet pile grooves and the bottom plate steel sheet pile grooves, and then sink the steel sheet piles; at the same time, repair the outer parts of the steel sheet piles tha...

Abstract

The invention discloses a construction method for additionally arranging a deep underground garage on the part of a basement. The construction method comprises the following steps that (1) a land mass with the basement is selected, and a construction area is determined; (2) upper backfill soil in the construction area is excavated; (3) vertical column piles, tension piles and steel plate piles are arranged underground in the set positions in a sinking mode, and a top plate and a bottom plate, damaged by construction of pile bodies, of the basement are repaired; (4) the original top plate and bottom plate, in an enclosure structure, of the basement are reserved, and thus foundation pit excavation is completed; and (5) the bottom plate is poured, parking platforms are constructed, and in the range of the enclosure structure, partial foundation piles, with the pile top elevations being lower than those of the tension piles, of the basement are reserved. The construction method for additionally arranging the deep underground garage on the part of the basement can be used for building the deep underground garage in an area without ground buildings or an area with demountable buildings and the basement, so that the number of underground parking spaces is increased, and the problem of difficult parking is relieved.

Description

technical field [0001] The invention relates to a construction method of an underground garage, in particular to a method for building a new underground garage in a part of a basement. Background technique [0002] At present, the number of underground garages in cities in my country is relatively small, especially in large and medium-sized cities with high population density, but there are a large number of shallow basements in urban areas, especially in business districts and some residential areas.
