Mud separator for air shaft cast-in-situ bored pile

Abstract

The invention discloses a mud separator for an air shaft cast-in-situ bored pile. The mud separator comprises a conveying mechanism and a mud separating device arranged above the conveying mechanism.The conveying mechanism comprises a conveying supporting plate and crawler track mechanisms arranged on the two sides of the conveying supporting plate. The mud separating device comprises a circularfiltering groove arranged above the conveying supporting plate, a vibrating sieve mechanism, a spilling box, a cyclone separator, a thick mud pool and a mud storing pool, wherein the vibrating sieve mechanism and the spilling box are arranged above the circular filtering groove, and the mud storing pool communicates with the spilling box. A drying box is arranged below a mud outlet of the vibrating sieve mechanism. The drying box is connected with a mud transporting vehicle of the exterior through the mud outlet. A crushing mechanism is arranged in the drying box. Multiple aerated pipelines are uniformly arranged on the bottom of the mud storing pool. The aerated pipelines communicate with an external air pump through an air pipe. The mud separator solves the problems that equipment is difficult to move, outside temperature has an influence on performance of mud, the occupied area of the mud drained to the outside is large, and the environment is polluted.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to a mud separator for bored piles of wind shafts. Background technique [0002] In the construction process of bridges and subway projects, cast-in-place concrete piles and percussion drills or rotary drilling rigs are often used to make underground holes. In order to ensure construction speed and safety, mud retaining walls must be used during drilling to avoid The collapse of the hole. In order to ensure the punching speed, it is also necessary to clean the hole during the percussion drilling process. A large amount of mud is required in the process of protecting the wall and clearing the hole. In order to reduce the cost, the mud needs to be recycled, so it is necessary to use a mud separator. The used mud is separated and purified so that the purified mud can be further used. [0003] In the construction process, the demand for mud is different, and the existing mud ...
