2, this non-excavation pipeline band water driving dredger, Dredge drill bit front end is alloy head, for the skiving to obturator, levigate; Outer wall adopts cylindrical shape protective cover, for the protection of former pipeline, avoids because the circular runout of alloy head rotation process damages pipeline; The inner auger stem form that adopts, forms spirality, for levigate obturator is transported to transmission auger stem.
3, this non-excavation pipeline band water driving dredger, adopt and transmit auger stem as conveyer, transmitting length and the diameter of auger stem determines according to the diameter of manhole and dredging caliber, transmit between auger stem, transmit between auger stem and the auger stem of Dredge drill bit and adopt screw thread or six square sets to be connected, be convenient to dismantle and assemble.
4, this non-excavation pipeline band water driving dredger, supporting mechanism adopts modular construction, in well, complete assembled, assembled latter two vertical bracing frame is separately fixed at the front-end and back-end of manhole, the bottom support frame of lower end and the circular support frame of upper end are supported on the borehole wall, for the thrust unit being arranged in fastening devices provides kick, bottom support frame and circular support frame are equipped with adjusting device, can adjust according to the size of manhole.
5, this non-excavation pipeline band water driving dredger, the outside vertical of two vertical bracing frames is fixed with fore-set, when manhole inwall is to rough irregular status, makes bracing frame stable support in manhole inwall.
6, the utility model scientific structure design is reasonable, and operating personnel need not go deep into pipeline, has reduced operating personnel's security risk; Can effectively dredge hard obturator (as cement block etc.); Only utilize existing manhole and pipeline to carry out operation, road pavement does not damage, and does not affect traffic, protection of the environment; Obturator, along with dredging is directly sent to inspection well head, has promoted operating efficiency; Do not damage former pipeline, the in the situation that of having underground water constantly to infiltrate, can carry out operation in well; It is a kind of Pipeline dredger with higher innovation.
