At the end of drilling (punching) the hole, during the period from lowering the reinforcement cage to pouring underwater concrete, the mud will precipitate. As the precipitated soil and the broken soil slag at the bottom of the hole are not consolidated, when the foundation pouring is completed to bear the load, the bottom soil of the hole is consolidated, the volume is reduced, causing subsidence and bearing capacity reduction. The failure of the bearing capacity of the punching pile to meet the design requirements is mostly caused by too thick sediment at the hole bottom. Therefore, great attention must be paid to ensure that the relative density, consistency and sand content of the mud are reduced, and the thickness of sediment at the bottom of the hole is removed and reduced. The allowable sediment thickness in the hole before pouring underwater concrete must meet the design requirements and specification requirements, I .e. the following standards are met: the mud weight is not more than 1.1, the sand content is less than 2%, and the viscosity is 17-20S. It is strictly prohibited to deepen the hole depth instead of hole cleaning.

It is strictly prohibited to deepen the hole depth instead of hole cleaning.
Hole cleaning is to use the kinetic energy of mud flowing to impact the sediment at the bottom of the pile hole, so that the rock particles and gravel in the sediment are in a suspended state, and then use the adhesive force of mud colloid to bring the suspended sediment out of the pile hole with the circulating flow of mud, and the sediment in the pile hole is cleaned up. After the hole of the punching pile is formed to the design elevation, the hole diameter, hole depth and verticality shall be checked. After the punching is confirmed to be qualified, the hole cleaning shall be started. The hole cleaning shall be done once after the final hole and once before pouring. The sediment after hole cleaning shall meet the design requirements.
The mud separator is mainly suitable for the mud treatment of large-diameter pile foundation, positive and negative cycle piling, rotary drilling piling, impact drilling piling, and mud treatment, purification and recovery of mud pipe jacking, shield engineering and ground continuous wall operations in modern foundation engineering construction.

Using the mud separator can create the following advantages for you:

1, the full purification of mud, control of mud indicators, reduce the sticking accident, improve the quality of hole-making.
2, the effective separation of soil ballast, improve the quality of hole-making, shorten the time of hole cleaning.
3, mud recycling, save slurry materials, reduce construction costs.
4. Closed-circuit circulation mode of mud and lower water content of ballast material reduce environmental pollution and transportation cost.
The use of WFL-100 type mud separator is helpful to the construction of related projects with high quality, high efficiency, economy and civilization!
