Problems solved by technology

Due to the characteristics of high mud content and high water content in the muck produced by shield tunneling, leakage will inevitably occur during transportation, causing certain pollution to the environment
In order to clean up the soil in time, a lot of cleaning water is consumed during transportation
Although the existing technology also uses some solid-liquid separation equipment to separate sand and mud, the effect still needs to be further improved

Abstract

The invention discloses a solid-liquid separation device for shield sediment treatment. The solid-liquid separation device is characterized by adopting a concave-convex slurry conveying pipe and comprising a pipe body, a dosing pipe arranged on the pipe body and a concave-convex structure which is located behind the dosing pipe and is formed by the pipe body. According to the solid-liquid separation device disclosed by the invention, a flocculant is added during slurry conveying by adopting the concave-convex slurry conveying pipe, the flocculation reaction time of slurry can be prolonged, andfollow-up solid-liquid separation treatment is facilitated.

Description

technical field [0001] The invention belongs to shield machine dregs processing equipment, in particular to a solid-liquid separation device for shield dregs treatment. Background technique [0002] With the rapid development of social economy, the construction of urban rail transit has become an important part of urban infrastructure construction. At the same time, a variety of environmental protection problems brought about by the construction of rail transit have always been a long-standing problem that plagues the government and construction parties. Among them, how to deal with the large amount of muck generated by shield tunneling construction is an important issue. Since the muck produced by shield tunneling has the characteristics of high mud content and high water content, leakage will inevitably occur during transportation, which will cause certain pollution to the environment. In order to clean up the soil in time, a large amount of cleaning water is consumed dur...
