Mud circular disposing device and using method thereof

Abstract

The invention discloses a mud circular disposing device and a using method thereof. The mud circular disposing device comprises a mud storage case and a three-way mud inlet pipeline, a roller type filter sieve opening and a clay stirring barrel opening are formed in the mud storage case, a roller type filter sieve is mounted at the roller type filter sieve opening, a clay stirring barrel is arranged below the clay stirring barrel opening in the mud storage case, and a mud stirrer is further mounted on the mud storage case; and the three-way mud inlet pipeline comprises a pipeline inlet, a first pipeline outlet and a second pipeline outlet, a three-way valve is mounted on the three-way mud inlet pipeline to control the pipeline inlet to communicates with the first pipeline outlet or the second pipeline outlet. The mud circular disposing device is assembled in a prefabricated mode, is used circularly and good in maneuvering performance, and simple in using method and can dispose the mud containing large granule gravel-cobbles and the mud containing clay chunks, the mud is almost free of wasting in the circular disposing process, mud consistency can also be adjusted to enable the mud to be used for a dado, a mud channel is isolated from the ground, seepage loss of mud water in the reflowing process is avoided, and water saving and environmental friendly effects are achieved.

Description

technical field [0001] The invention relates to the field of geotechnical engineering construction, in particular to a mud circulation treatment device and a use method thereof. Background technique [0002] In the construction of geotechnical engineering, bored piles generally use positive circulation or reverse circulation to carry out rotary drilling. Whether in positive circulation or reverse circulation construction projects, pits are excavated on the site on the site and realized through tunnels. Slurry and sediment are stored, and the return of the upper layer of slurry is realized through the channel, but the disadvantages of this type of drilling are obvious: a certain amount of free space is required, and a large amount of sediment is required to be excavated with mechanical cooperation, and the moisture content and mud content of the sediment are high. The transportation cost is relatively high and pollutes the environment. During the mud return process of the ori...

Problems solved by technology

Due to construction cost and site problems, such large mud circulation tanks and mud circulation devices are difficult to implement, and a device with simple structure, low cost and high efficiency is required for this type of project

[0003] At the same time, the mud circulation system that has been applied in the existing large-scale municipal traffic projects is all for the treatment of mud containing fine particles, such as sand-containing mud, clay mud, etc. If there are large-diameter pebbles in the soil layer, it is also necessary It is crushed by the drill bit system of large equipment (such as double-wheel milling and slotting machine) and then enters the circulation steps such as mud and slag removal. This method is obviously not suitable for all projects, especially small and medium-sized projects.
