Problems solved by technology

At present, the general way of transporting mud outside is by sealed vehicles. This method has the following disadvantages: on the one hand, the transport speed is relatively slow, and a large amount of equipment must be invested, resulting in increased costs and slow construction period; The outflow of mud will affect the environment

Embodiment Construction

[0011] A method of processing construction surplus mud of the present invention, comprises the following steps:

[0012] (1), put cement into the remaining mud after construction and stir;

[0013] (2) After the mud settles, drain the surface water;

[0014] (3), transport the remaining sludge out for disposal.

[0015] In the present invention, cement is put into the mud, and after being stirred evenly, the surface clear water is separated through cement and soil, sand, and gravel particles in the mud to bond and settle, and the surface clear water can be directly pumped and drained to quickly and effectively remove the remaining The sludge is loaded and transported out, thereby reducing the amount of mud treatment, reducing the total cost of mud treatment, and effectively preventing the environment from being affected by the mud.

[0016] As a preferred embodiment, before step (1), measure the specific gravity, sand content, and colloidal index of the remaining mud during ...

Abstract

The invention discloses a method for treating constructed residual mud, which comprises the following steps of: (1) putting cement into the constructed residual mud and stirring the mud; (2) after the mud is settled, pumping clean water on the surface layer; and (3) conveying the mud residue to the outside and treating the mud residue. By putting the cement into the mud, stirring the mud uniformly, separating the clean water on the surface layer by cementation and settlement of the cement and soil, sand and broken stone granules in the mud and directly pumping and treating the clean water on the surface layer, the mud residue can be quickly and effectively discharged, so that the treatment formula quantity of the mud is reduced, the total treatment cost of the mud is reduced and the environment can be effectively prevented from being affected by the mud.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for processing surplus mud during construction. Background technique [0002] In the construction process of underground diaphragm wall and cast-in-situ pile, a large amount of mud is required. Among them, a part of the mud can be recycled, and the excess mud must be shipped out. At present, the general way of transporting mud outside is by sealed vehicles. This method has the following disadvantages: on the one hand, the transport speed is slow, and a large amount of equipment must be invested, resulting in increased costs and slow construction periods; The outflow of mud will affect the environment. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for treating construction residual mud with fast cleaning speed, low investment and no impact on the environment. [0004] The...
