AI Technical Summary

Technical Problem

When treating soft soil foundations using the pumping method, sand and gravel can clog the filter openings, leading to a decrease in pumping efficiency and failing to meet the drainage speed requirements of the project.

Method used

By installing threaded first and second drain pipes in the device, the airflow generated by the air pump is used to back-blown the filter port, and the sand and gravel are separated from the water by combining the vibrating screen frame and the sedimentation tank, ensuring that the filter port is unobstructed. The length of the pipes can be adjusted by threading to adapt to soft soil foundations of different depths.

Benefits of technology

It effectively disperses accumulated sand and gravel, keeps the filter opening unobstructed, improves pumping efficiency and the applicability of the device, and adapts to the treatment needs of soft soil foundations at different depths.

Abstract

The utility model discloses a highway soft soil foundation treatment device belongs to soft soil foundation treatment field, and the inside connection of mounting panel has first drain pipe, and the outer surface of first drain pipe is equipped with filter mouth, and the inner wall of first drain pipe is equipped with thread, and the inner wall of first drain pipe is equipped with second drain pipe through thread connection, and the one end of second drain pipe away from first drain pipe is connected with flange, and the outer surface of flange is connected with connecting pipe, and the outer surface of connecting pipe is equipped with valve, and the upper surface of mounting panel is equipped with air pump, and the output of air pump is connected with the outer surface of second drain pipe. The utility model discloses through closing the valve and blocking the drainage channel of second drain pipe, the air flow of air pump output will gather in the pipeline at this moment, and with the incompressible characteristics of water, the strong pressure is formed, and the filter mouth is carried out reverse purging, can have the sandstone of forceful dispersion accumulation, significantly reduces the jam situation, thereby lasting guaranteeing the unobstructed of filter mouth.
