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, which comprises the following steps: step 1, setting a ring of water barriers around the edge of the weak soil zone, and vertically setting hollow pipe piles in rows in the weak soil zone; step 2, Take two adjacent rows of pipe piles as a unit, and set multiple partition plates between the two adjacent units. The multiple partition plates are connected end to end and distributed in a zigzag shape. The two rows of pipe piles in each unit Set a row of reinforcements between them; Step 3, spray concrete multiple times in the deep layer of each unit; Step 4, lay geogrid, straw layer, steel wire grid, and graded gravel in sequence on the surface of the filled concrete from bottom to top . The invention enhances the compactness of weak soil and improves the shear strength of weak soil.

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 ...
