Mud on-site separation device and separation method

Abstract

The invention relates to the technical field of waterproofness and anti-permeability in the building field, and particularly relates to a mud on-site separation device. The mud on-site separation device comprises a vacuum pump, a water storage tank, a support cage, filter cloth and a water pumping pipe, the vacuum pump is communicated with one end of the water pumping pipe, the water storage tankis connected onto the side wall of the water storage tank through a pipeline, the other end of the water pumping pipe extends into the bottom part of the support cage, and the filter cloth is wrappedat the outer part of the support cage. The building mud is processed by a mud dehydration recycle device, an effluent is recycled to serve as production water for the construction site, the water resource is saved, the aggregate is reused as a resource, and a mud cake is used as backfilling earthwork. After the building mud is treated, the moisture content is reduced to about 27% from 61%, the weight loss ratio of the volume of the mud is 47%, and the goal of minimization is achieved.

Description

technical field [0001] The invention relates to the technical field of waterproofing and anti-seepage in the field of construction, in particular to an on-site mud separation device and a separation method thereof. Background technique [0002] In the construction process of cast-in-situ pile foundation, shield tunneling, underground diaphragm wall, mining and other industries in the prior art, the pump suction reverse circulation hole forming process is usually used, that is, the rock and soil produced by drilling are stirred into thick mud with water or thin mud Pump it out. This construction process will produce a large amount of high-concentration construction mud. At present, there is no suitable technology for on-site separation of this construction mud. It can only be transported by mud tanker or ship, resulting in high transportation costs and damage. serious pollution of the environment. Contents of the invention [0003] The purpose of the present invention is t...

[0002] In the construction process of cast-in-place pile foundation, shield tunneling, underground diaphragm wall, mining and other industries in the prior art, the pump-suction reverse circulation hole-forming process is usually used, that is, the rock and soil produced by drilling are stirred into thick mud with water or thin mud Pump it out. This construction process will produce a large amount of high-concentration construction mud. At present, there is no suitable technology for on-site separation of this construction mud.
