Description

A vibrating sand filter machine for filtering the mud of percussion bored pile cleaning

technical field

The utility model relates to a hole-clearing device for impact bored piles in underground engineering of bridge piers, in particular to a vibrating sand filter for filtering mud for clearing holes for impact bored piles.

Background technique

In the construction process of the underground engineering of bridge piers, according to the different terrain and geological conditions, the construction techniques used are completely different. One is to use the method of digging holes, and the other is to use the method of punching holes. Usually, the method of punching holes is used. There are many methods, and the punching method is completely mechanized operation, which has higher construction efficiency and less safety risk. However, during the percussion drilling construction process, it is necessary to continuously inject water into the pile hole to realize the purpose of real-time hole cleaning. The traditional method is to discharge the mud with high mud content produced by percussion drilling into the storage tank for natural sedimentation, and it can be used again after the mud sand and slag with large particles are completely settled, which requires a long time for sedimentation , especially delaying the construction period, it is also necessary to excavate a large area of mud pool. In places with abundant water resources, a construction unit directly discharges the mud from the cleaning hole into the river, and every time it is injected into the pile hole, it is clean water, which not only wastes water resources, but also causes great pollution to the river. , Some units also use the method of passing through the cone sand filter to filter the mud, but the effect is not very good.

Contents of the invention

The purpose of the utility model invention is to provide a vibratory sand filter for filtering the mud of percussion bored piles, and to replace traditional The natural sedimentation method saves the process of excavating a large-scale mud pool, directly transports the mud discharged from the clear hole to the sand filter machine, and filters out the larger mud sand and waste residue through vibration and gravity, and recycles it after rapid filtration. It achieves the purpose of efficiently controlling the sand content of the mud injected into the bored pile for the second time, and realizing the purpose of rapid hole cleaning.

The purpose of the utility model invention is achieved by implementing the following technical solutions

A vibratory sand filter machine for filtering the mud of percussion drilling pile clearing holes, comprising a sand filter machine cabinet, a slurry filter box, a slurry inlet pipe, and a slurry storage box, characterized in that: a filter slurry box is arranged on the sand filter machine cabinet , a filter screen is provided at the bottom of the filter box, a slag outlet is provided at the lower end of the filter screen, and a slurry outlet is provided at the bottom of the sand filter cabinet at the lower end of the filter screen, and the slurry outlet passes through the pipeline and the impact drill connected by hole piles; a vibrating spring is arranged between the filter slurry box and the sand filter machine cabinet, a vibrating shaft is set on the filter slurry box, and a motor is set on the side of the sand filter machine cabinet at the lower end of the vibrating shaft, and the motor and A conveyor belt is arranged between the vibrating shafts; the vibrating shaft, the filter pulp box and the vibrating spring are set as a whole and fixed in the center of the sand filter cabinet; a pulp storage box is arranged on the top of one end of the sand filter cabinet, A pulp inlet pipe is arranged on one side of the pulp storage box.

The utility model invention has the advantages that: a vibrating sand filter machine for filtering the mud of percussion bored pile cleaning, adopts the method of adding a sand filter device in the process of conveying the mud discharged in the pile hole to replace the traditional natural The sedimentation method saves the process of excavating a large-scale mud pool, directly transports the mud discharged from the clear hole to the sand filter machine, and filters out the larger mud sand and waste residue through vibration and gravity, and recycles it after rapid filtration to achieve Efficiently control the sand content of the secondary injected bored pile mud to achieve the advantages of rapid hole cleaning.
