Device and method for continuous directional dredging of trenchless pipe network box culvert

Abstract

According to the device and method for continuous directional dredging of the trenchless pipe network box culvert, the trenchless drilling machine main machine is arranged, and the dragging plate device is driven to be dragged back and forth in the box culvert through transmission of a plurality of drill rods and couplings, so that sludge is transferred to a working position, pumping and harmless treatment are facilitated, and the working efficiency is improved. An operator only needs to operate the main machine of the trenchless drilling machine, manual dredging is replaced, and the working efficiency is improved; continuous and efficient dredging of the box culvert is achieved, the safety risk of manual operation is avoided, the number of excavation working positions is greatly reduced, normal operation is achieved under the condition that ground structures and the surrounding environment are not affected, sludge can be thoroughly removed, the overflowing capacity of the box culvert is ensured, and the influence of internal pollution on water quality is effectively reduced.

Description

technical field [0001] The invention relates to the field of dredging devices, in particular to a device and method for continuous and directional dredging of trenchless pipe network box culverts. Background technique [0002] With the continuous development of urban infrastructure, especially the development and utilization of underground space is the focus of the advanced level of urban infrastructure. Among them, the urban drainage pipe network system is an important part and a decisive link in determining the ability of the entire city to resist flooding. Therefore, the daily dredging and maintenance of urban drainage pipe network is very important, especially the dredging and dredging of large underground box culverts designated as urban drainage main channels. [0003] When the silt inside the box culvert is serious, the drainage capacity is greatly reduced compared with the design standard, causing great waterlogging hazards to the upstream area, and the diversion of ...

AI Technical Summary

Problems solved by technology

Since the box culvert pipe network is usually located in the living area and the surrounding environment is relatively complex, it needs to be broken and excavated. In actual work, usually a hoisting hole needs to be excavated about 50m away. Since the box culvert is a closed space, the silt is fermented and vulcanized. Hydrogen poisonous gas has a very high safety risk, and at the same time, the workload is extremely heavy, and the work efficiency is severely limited
