Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] The working principle of the present invention is to use several sets of steel conveyor belts with perforated ribs in the box to lift the fed slurry multiple times. During the lifting process, the slurry and water will fall to the bottom of the box under the action of gravity. It enters the slurry collection box through the slurry outlet and can be reused; part of the soil residue that falls to the bottom of the box is scraped into the conveyor belt again by the conveyor belt rib for lifting, and finally all the soil residue is discharged to the external soil collection box through the soil residue outlet with the conveyor belt, so that Achieve slurry separation.

[0030] see Figure 1-6 , the gravity type slurry separation system of the present invention comprises a box body 1, and the box body 1 is provided with a slurry inlet 11, a slurry outlet 12, a soil...

Abstract

The invention relates to a drilled slurry-mud separating device and a slurry-mud separating process, in particular to a gravity type slurry-mud separating system and the slurry-mud separating process. The gravity type slurry-mud separating system comprises a box body, a slurry inlet, a slurry outlet and a mud residue outlet are formed on the box body, and a plurality of conveying belts are arranged in the box body. Compared with the prior art, the gravity type slurry-mud separating system has the advantages that slurry liquid and the mud residue in mud can be lifted up by the conveying belts in the box body, slurry-mud separation is realized under the action of gravity, the slurry liquid is recovered and reused, total mud drainage is greatly reduced, the mud is prevented from overflowing in all directions, construction is enabled to be carried out under neat, environment-friendly and well-organized conditions, and requirements on civilized construction are more effectively met.

Description

technical field [0001] The invention relates to a mud separation device and a mud separation process for bored piles, in particular to a gravity mud separation system and a mud separation process. Background technique [0002] In the field of construction engineering, bored piles are mostly used in the foundation design, and the piles should be used in cities or densely built areas. During the construction process, it is necessary to use mud to protect the hole wall, carry drill cuttings out of the hole, and cool the drill bit. Therefore, a large amount of mud will be generated during construction. The amount of mud generated in general projects is 3-4 times that of cast-in-place piles. At present, mud can only be transported and discharged to cultivated fields or out of rivers and rivers. There are pollution risks during transportation and discharge, which brings hidden dangers to environmental protection. Contents of the invention [0003] The purpose of the present inv...
