AI Technical Summary

Technical Problem

Existing road drainage ditch dredging devices require frequent disassembly and installation when dealing with long-distance blockage areas, and the lack of effective support results in low dredging efficiency.

Method used

A road drainage ditch dredging device was designed. By setting inserts, clamps, extension frames and high-pressure rotating nozzles on the main body of the dredging device, the extension components and transmission system are used to realize the extension and movement of the device, and the silt is cleaned by high-pressure water flow. The device's stability and disassembly are ensured by the combination of limiting and stabilizing structures.

Benefits of technology

It enables efficient dredging of long-distance blocked areas, reduces the workload of construction workers, improves dredging efficiency, and solves the problem of frequent disassembly caused by the limited length of the device.

Abstract

The application discloses a road drainage ditch dredging device and a dredging method thereof, relates to the technical field of drainage ditch dredging, and comprises a dredging main body and a drainage ditch. The outer wall of the dredging main body is fixedly connected with plug blocks on two sides, the outer wall of the plug blocks is slidably connected with clamping plates, the outer wall of the clamping plates is in contact with the inner wall of the drainage ditch, one side of the outer wall of the dredging main body is fixedly connected with a traction block, the inner cavity of the traction block is slidably connected with a flow guide pipe, one end of the flow guide pipe is fixedly connected with a high-pressure rotary nozzle, and the bottom of one side of the inner wall of the dredging main body is fixedly connected with an extension frame. The tooth trace pushing assembly block and the mounting block are slid on the surface of the extension frame, and the traditional road drainage ditch dredging device is further solved in the using process. Since the existing pipeline dredging device lacks support, when facing a long-distance blocked area, the corresponding well lid often needs to be removed by the construction personnel, which not only has a large workload, but also has low dredging efficiency.
