A kind of silt, quicksand ground treatment method

Abstract

The invention discloses a method for treating silt and quicksand foundations, which comprises the steps of: removing a certain height of silt and quicksand in untreated silt and quicksand foundations to form cleaned silt and quicksand layers; Aggregate is backfilled in the quicksand layer to the design elevation, and the aggregate hits the silt and quicksand layer and integrates with the silt and quicksand layer to form a treated silt and quicksand foundation. The present invention adopts partial removal of silt and quicksand in the foundation to form silt and quicksand layers, and then smashes and backfills the aggregate into the silt and quicksand layers to integrate the aggregates with the silt and quicksand layers, which not only reduces the The cleaning amount of silt and quicksand reduces the input of labor and materials, and can also use the characteristics of the silt and quicksand layer itself to increase the bonding performance between aggregates, form a firm and stable whole, and improve the sludge after treatment. Structural strength of quicksand foundation.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a method for treating silt and quicksand foundations. Background technique [0002] Building foundation engineering is of great importance, involving the safety of the entire project structure, especially for projects with weak foundations and complex foundation conditions. If the foundation is not handled properly, the most direct consequence is uneven settlement of the building and cracking of the foundation raft Such quality problems endanger the structural safety and function of the entire building. [0003] For the traditional foundation treatment method, the method of dealing with complex foundations such as silt and quicksand is usually the concrete replacement method. The concrete replacement method needs to clean up the weak foundation layers such as silt and quicksand before pouring into the weak foundation area. Concrete up to the design level of the foundation...

AI Technical Summary

Problems solved by technology

[0005] (1) Since this project is a pile-raft foundation, the distance between the piles is relatively close. If the mud and quicksand are cleaned manually, it will be labor-intensive and time-consuming;

[0006] (2) If the mud and quicksand are cleaned by machinery, it will inevitably cause damage to the pile foundation, and the integrity of the pile body cannot be guaranteed;

[0007] (3) Replacement with concrete replacement method, high cost and low profit
