Drainage pipeline dredging device adopting horizontal directional drill

Abstract

The invention provides a drainage pipeline dredging device adopting a horizontal directional drill. The device comprises a high-pressure pump, a horizontal directional drilling machine, a dredging pupjoint and a horizontal directional drill bit; the horizontal directional drilling machine is provided with a hollow drilling rod; one end of the drill rod is connected with a high-pressure pump, theother end is connected with one end of the dredging pup joint, and the other end of the dredging pup joint is connected with one end of the horizontal directional drill bit; a plurality of nozzles arearranged at the other end of the horizontal directional drill bit; the drill rod is further sleeved with a plurality of rolling tripods, and a plurality of oblique jetting holes inclining towards thedrill rod are formed in the desilting pup joint; the drill rod stretches into a drainage pipeline, the desilting pup joint is drilled into silting, and fluid is jetted through the nozzle and the oblique jetting holes to destroy the silt from the interior. The invention has the beneficial effects that sundries with large weight, large size and high adhesion in a drainage pipeline can be cleaned, the dredging effect is greatly improved, the whole dredging process can be completed by a machine, a manual underground operation is not needed, and the safety and reliability are achieved.

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. ...

AI Technical Summary

Problems solved by technology

Most of these methods are designed for the dredging of drainage pipes with small length and diameter, and the dredging efficiency is not high for completely blocked long drainage pipes, and even cannot be cleaned.
