Embodiment Construction

[0011] Further illustrate the present invention below in conjunction with accompanying drawing.

[0012] Such as figure 1 Shown, the subway station side soil reinforcement construction method of the present invention comprises the following steps:

[0013] (1) Divide the construction blocks for the soil on one side of the subway station. Since the longitudinal length of the reinforcement range is relatively long, the construction blocks are divided by the longitudinal length of the soil to be reinforced.

[0014] (2) Carry out the reinforcement construction of stirring piles to each construction block in turn, and adopt the method of "jumping warehouse" construction when constructing each construction block;

[0015] (3) When constructing each construction block, first construct a row of piles closest to the side of the subway station as isolation piles. After the row of piles is formed, push the construction to the outside of the subway station. Jump driving is used for the ...

Abstract

The invention discloses a construction method for reinforcing soil body on one side of a metro station, which comprises the following steps: V1ing, the soil body on one side of the metro station is divided into construction blocks, and the construction blocks are sectionally divided on the longitudinal length of the reinforced soil body. V2ing, the construction blocks are orderly done with a stirring pile reinforcement construction, and a jumping bin construction mode is used when each construction block is constructed. V3ing, when each construction block is constructed, a row of piles which are close to one side of the metro station is firstly constructed and are used as isolation piles, after the row of piles are formed, the outer side of the metro station is constructed, and a jump beating mode is used when the row of piles are constructed. Through optimizing a reinforcing process of a stirring pile soil body, the construction method of the invention uses the mode of partition construction and jumping pin construction, the effect to the metro station when the soil body on one side of the metro station which is reinforced is capable of being effectively solved, and the deformation of the metro station is reduced.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction method for soil reinforcement on one side of an existing subway station in a new underground project. Background technique [0002] With the development of the city, the population increases rapidly, leading to an increase in vehicles, which brings a series of problems such as traffic congestion, environmental pollution and energy crisis to the city. Compared with other means of transportation in the city, the subway, in addition to avoiding urban ground congestion and making full use of space, also has the advantages of large capacity, fast and pollution-free. However, in the construction of subway stations, especially when constructing new underground works on the side of existing subway stations, soil reinforcement is often required. Conventional soil reinforcement construction methods include cement-soil mixing piles, high-pressure rotary grouting piles, etc. ...
