Drainage pipeline desilting device adopting horizontal directional drill

Abstract

The invention discloses a drainage pipeline desilting device adopting a horizontal directional drill, and belongs to the technical field of municipal drainage pipeline non-excavation repair equipment. Comprising a horizontal directional drilling machine, a high-pressure water pump, a sludge conveying device, a sludge stirring device, a cutting disc, a reamer head and a high-pressure nozzle, the sludge conveying device comprises a sludge conveying pipeline and a spiral conveying mechanism, the spiral conveying mechanism is arranged in the sludge conveying pipeline, and the horizontal directional drilling machine is in driving connection with the spiral conveying mechanism; the sludge stirring device is provided with stirring fan blades, a cutting disc is arranged at the front end of the sludge stirring device, a reamer head is arranged in the center of the cutting disc, high-pressure nozzles are uniformly arranged at the top ends of the cutting disc and the reamer head, and the high-pressure nozzles are connected with a high-pressure water pump pipeline. The drainage pipeline dredging device is simple in structure, people do not need to enter the drainage pipeline, and the drainage pipeline can be conveniently and effectively dredged.

Description

technical field [0001] The invention relates to the technical field of non-excavation repair equipment for municipal drainage pipes, in particular to a drainage pipe dredging device using horizontal directional drilling. Background technique [0002] The urban drainage pipeline system is an indispensable and important municipal infrastructure in a modern city, and it is also a backbone project for urban water pollution prevention and urban drainage, drainage and flood control. The drainage pipeline system is responsible for collecting and transporting domestic sewage, industrial wastewater and atmospheric precipitation generated in urban production and living, and timely and reliably removing the collected domestic sewage, industrial wastewater and atmospheric precipitation, so as to protect the urban area from the harm of sewage and wastewater , from flooding on the road during heavy rain, thus providing people with a safe and comfortable production and living environment. ...

Problems solved by technology

These methods require operators to enter the drainage pipes. The working environment in the drainage pipes is poor and gives off a strong smell, so it is difficult to work for a long time and the work efficiency is low. The suction of the suction pump is difficult to suck and recycle the consolidated sedimented sludge from the hose nozzle, so the sludge is not cleaned thoroughly
