Description

Multifunctional mud circulation equipment

Technical Field

The utility model belongs to the technical field of bored piles in bridge engineering, and particularly relates to multifunctional slurry circulation equipment.

Background

The bored pile construction process is widely applied to the field of bridges. In the construction process, mud circulation and mud retaining walls play a decisive role in pile foundation pore-forming quality. At present, a conventional slurry circulation system generally needs to excavate a slurry tank and a sedimentation tank at a construction site, which can cause a certain damage to the environment, and in some special construction scenes such as water, complex mountain areas and the like, the conventional slurry circulation scheme becomes difficult to implement due to lack of a construction platform. In addition, in actual field construction, the constructors are accustomed to preparing the mud within the pile hole, which makes the mud preparation slow. In-hole pulping also causes waste of materials due to lack of sufficient stirring. When slurry leakage occurs due to poor geology such as karst cave and cracks, the slurry is slowly prepared, so that enough high-quality slurry cannot be timely supplemented, and the phenomenon of hole collapse occurs in a neutral period before the slurry is qualified in preparation. In addition, in-situ soil is adopted in the current mud preparation in site construction, the control of mud indexes depends on the experience of workers, but the mud properties of the mud prepared by different kinds of soil are greatly different, the site can only make preliminary judgment on the consistency of the mud, and the wall protection effect of the mud cannot be quantitatively controlled. The traditional quantitative measurement of the mud indexes mainly depends on 'three-piece set of mud', and because the measurement is time-consuming and labor-consuming, the 'three-piece set of mud' is mostly adopted for measurement when 'hole cleaning' is performed, so as to judge whether the condition of pouring pile foundation concrete is met, and the mud indexes in the whole construction process cannot be monitored. Therefore, the pore-forming quality in the whole construction process is difficult to ensure, and the waste of slurry preparation is caused.

Therefore, there is a need to design a multi-functional mud circulation apparatus.
