Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0026] The invention provides a kind of weak soil reinforcement processing method, comprises the following steps:

[0027] Step 1. Set up a circle of baffles 1 around the edge of the weak soil zone, and vertically set hollow pipe piles 2 in rows on the weak soil zone. The distance between two adjacent pipe piles 2 in each row is 1 meter. The pipe piles 2 in two adjacent rows correspond one by one. The pipe piles 2 sink to 1 meter below the soft soil layer. The pipe piles 2 are inserted into the steel cage and then covered by the cover body. 1 includes a first partition, a second partition, and a plurality of connecting ribs, the first partition and the second partition are arranged in parallel and are all steel plates, and a plurality of connecting ribs are arranged at intervals on the...

Abstract

The invention discloses a soft soil reinforcement treatment method. The method comprises the following steps that S1, a circle of water-stop sheets are arranged around the edge of a soft soil zone, and hollow tubular piles are vertically arranged in the soft soil zone in rows; S2, every two adjacent rows of tubular piles serve as a unit, multiple partition plates are arranged between every two adjacent units, the multiple partition plates are connected end to end and distributed in a zigzag mode, and a row of reinforcing pieces are arranged between the two rows of tubular piles of each unit; S3, concrete is deep sprayed in each unit multiple times; and S4, geogrids, a straw layer, a steel wire net frame and graded broken stone are sequentially laid on the surface of the injected concrete from bottom to top. According to the method, the compactness of the soft soil is enhanced, and the shear strength of the soft soil is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a soft soil reinforcement treatment method. Background technique [0002] Weak soil refers to fine-grained soil with high natural water content, large pores, high compressibility, and low shear strength deposited in coastal areas, lakes, valleys, and river beaches. Weak soil includes silt, muddy soil, flush fill, miscellaneous fill, and saturated loose silt and fine sand and silt. Such soils have poor engineering properties. However, with the development of the economy, various engineering construction projects are increasing, among which construction on weak foundations is more common. Weak foundation refers to the compressed layer, which is mainly composed of silt, muddy soil or other highly compressible soil. If the handling measures are improper, it will affect the stability of the main body of the project. Therefore, how to strengthen the weak soil used ...
