A seawater slurry conditioner

Abstract

The invention relates to the technical field of construction of underground engineering and particularly relates to a seawater mud adjusting agent. The seawater mud adjusting agent comprises following raw materials in percentage by weight: 1%-2% of a glue type mixture, 0.5%-1% of a fermentation mixture, 0.1%-0.5% of a thickening agent and the balance of water. The seawater mud adjusting agent has the advantages that seawater can be directly utilized and the seawater mud adjusting agent has high viscosity, colloid fraction, no toxin and no pollution when being compared with fresh water mud; the seawater mud adjusting agent is good for improving the overall performance of the mud and is also good for energy conservation and emission reduction of the construction engineering.

Description

technical field [0001] The invention relates to the technical field of underground engineering construction, in particular to a seawater slurry conditioner. Background technique [0002] The bored pile is a cylindrical foundation formed by mechanically drilling holes and pouring concrete in situ. In the field of highway bridge foundation engineering, bored pile foundation occupies an important position. During the drilling of piles, a large amount of engineering mud is required to protect the hole wall and carry slag to the ground. Traditional engineering mud is mainly composed of raw soil, silt, fine sand, clay, bentonite, thickener, soda ash, etc. During the preparation and adjustment of mud, a large amount of fresh water is required because the salt content in seawater is relatively high , will cause the mud to be layered up and down, thereby increasing the risk of hole collapse and affecting the construction and pile quality. In the marine environment, it is very diff...

Problems solved by technology

Traditional engineering mud is mainly composed of raw soil, silt, fine sand, clay, bentonite, thickener, soda ash, etc. During the preparation and adjustment of mud, a large amount of fresh water is required because the salt content in seawater is relatively high , will cause the mud to be layered up and down, which will increase the risk of hole collapse and affect the construction and pile quality

In the marine environment, it is very difficult to obtain fresh water, and the transportation and use of fresh water will greatly increase the construction cost; secondly, even if fresh water is used for slurry making and mixing, due to the poor dispersion, slag carrying and suspension capabilities of ordinary mud, The comprehensive performance index of the mud still cannot meet the needs of construction; finally, the common tradition needs to add bentonite and soda ash, and bentonite is a limited natural resource, and its large-scale mining and use will cause waste of resources, and will pollute the environment and block the river , fill up the riverbed, the use of soda ash will cause alkalization of the surrounding land
