Sand removing system for underground connecting wall in river-facing water-rich silty-fine sand layer
The invention belongs to the technical field of underground connecting wall construction, and particularly provides a sand removing system for an underground connecting wall in a river-facing water-rich silty-fine sand layer. The system comprises a slurry discharge pipe, a groove section, a slurry inlet pipe, a new slurry tank, a centrifugal machine, an air compression mechanism, a separated liquid discharge port, a slag discharge mechanism, a circulating slurry tank and a first pipeline. According to the technical scheme, the performance of the diaphragm wall slurry is improved by using the centrifugal machine, the sand removing efficiency of the slurry is improved, hole collapse and necking of the diaphragm wall are prevented, the centrifugal machine supplements new slurry while removing sand, the sand content of the slurry is reduced, the specific gravity and viscosity of the slurry can be guaranteed, the phenomena of mud inclusion and slag inclusion in the concrete pouring process are effectively reduced, the construction quality of the underground diaphragm wall is improved, the probability of water leakage and even water and sand burst of the underground diaphragm wall in the later excavation process is reduced, and engineering risks are avoided.
本发明属于地连墙施工技术领域，具体提出了一种临江富水粉细沙层中地连接墙除砂系统。包括：排浆管、槽段、进浆管、新浆池、离心机、空压机构、分离液排出口、出渣机构、循环浆池和第一管道。本发明提出的技术方案通过使用离心机改善了地连墙泥浆性能、提高了泥浆除砂效率、防止了地连墙坍孔、缩颈，离心机在除砂同时补入新浆，在降低了泥浆的含砂率的同时，能够保证泥浆比重及黏度，有效的减少混凝土浇筑过程中夹泥、夹渣的现象，提高了地连墙的施工质量，降低后期开挖过程中地连墙渗漏水甚至涌水涌砂的几率，规避工程风险。
