The utility model provides a non-excavation-type pipeline replacement device, which comprises a drill rod and a drill bit, wherein one end of the drill bit is fixedly connected with the drill rod, and the other end of the drill bit is fixedly connected with a to-be-replaced new pipe; the side surface, facing one side of the drill rod, of the drill bit is provided with a friction-increasing component used for expanding a used pipe; the drill bit is fixedly connected with the new pipe through a connecting ring, and the connecting ring is flush and fitted with the end face of the new pipe and the end face of the drill bit. The non-excavation-type pipeline replacement device provided by the utility model has the beneficial effects that the original used pipe is expanded though the friction-increasing component so as to perform rapid pipeline replacement; the drill bit and a connecting structure of the drill bit and the new pipe are reasonable; time and strength are saved, and the universality is high; the non-excavation-type pipeline replacement device is suitable for replacing pipelines with various pipe diameters, and is rapid and convenient in operation.
Description
Technical field
The utility model relates to trenchless engineering field, is specifically related to more changing device of a kind of non-digging pipe.
Background technique
Trenchless technology is widely used abroad, also universal gradually at home.Do not need to excavate ground, just energy highway crossing, railway, river even can pass under building, are a kind of method of construction that can carry out safely and effectively environmental protection.Trenchless technology does not excavate ground, so the upper soil horizon that is laid pipeline is without disturbance, the tube coupling end of pipeline is difficult for producing the poor distortion of section, and its pipeline life is also greater than excavation method pipe laying.Adopt trenchless technology under room can save a large number of expropriation of land removal expense, reduce moving room, shorten length of pipeline, have very large economic benefit.
Also there is corresponding harsh technical requirements in trenchless technology, need to calculate the minimum diameter that needs pore-forming according to the diameter of channelling and radical, can not be excessive, also can not be too small, drilling diameter is excessive, and around channelling, soil layer caves in and easily causes road surface to sink, and drilling diameter is too small, can make trombone slide resistance increase, cause de-pipe or pipe deforming.Existing method of construction and equipment can only be applied to the construction environment of not laying piping, and the situation of carrying out pipeline replacing by trenchless technology there is no effective equipment or instrument at present.
Summary of the invention
The utility model, for above-mentioned technical problem, provides more changing device of a kind of non-digging pipe.
Goal of the invention of the present utility model realizes by following scheme: non-digging pipe is changing device more, comprise drilling rod and drill bit, drill bit one end is fixedly connected with the other end and is fixedly connected with new pipe to be replaced with drilling rod, drill bit has for the increasing of the old pipe of the spreading parts that rub towards the side surface of drilling rod one side.
Further, described drill bit is fixedly connected with new pipe by a connecting ring, connecting ring and new pipe and the concordant adaptation of bit face.
Further, described drill bit side surface is to one end axial shrinkage near drilling rod.
As preferably, the increasing of the described drill bit side surface parts that rub are outside thread.
As another preferred version, the increasing of the described drill bit side surface parts that rub are the cutting fin being arranged on drill bit side surface, and cutting fin end has cutting inclined-plane.
Further, described drill bit is Rotational Symmetry shape, and cutting fin and bus are inclination angle and arrange.
Further, described connecting ring is PE material, and connecting ring one end is welded and fixed with new pipe, and the other end and drill bit are welded and fixed.
Further, described drill bit is connected with drilling rod buckle or keyway connection.
Further, described bit face is rounded, diameter range 160mm～200mm.
Further, described drilling rod tail end is provided with the power plant for rotation traction traction drilling rod.
The beneficial effects of the utility model are: rub the former pipe of haveing been friends in the past of parts spreading to carry out pipeline quick-replaceable by increasing; Drill bit and drill bit and new pipe connecting structure are reasonable, time saving and energy saving and versatility good; The pipeline that is applicable to various calibers is changed, and operates quick and convenient.
Brief description of the drawings
Fig. 1 is the utility model embodiment one structural representation.
Fig. 2 is the utility model embodiment two structural representation.
Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail:
embodiment one
Shown in Fig. 1, more changing device of non-digging pipe of the present utility model, comprise drilling rod 1 and drill bit 2, drill bit 2 one end are fixedly connected with the other end and are fixedly connected with new pipe 3 to be replaced with drilling rod 1, and drill bit 2 has for the increasing of the old pipe 4 of the spreading parts 2A that rubs towards the side surface of drilling rod 1 one sides.
Intact for ensure new end surfaces as far as possible, drill bit 2 is fixedly connected with new pipe 3 by a connecting ring 5, connecting ring 5 and new pipe 3 and the concordant adaptation of drill bit 2 end face.To adapt to whole installation passage, prevent from stopping up or passage breakage.
For ease of fast and effeciently breaking through old pipe 4, drill bit 2 side surfaces are to one end axial shrinkage near drilling rod 1.The tapered setting of drill bit, shabby pipe ensure that old pipe chip has enough placement spaces fast rises.
In the present embodiment, the increasing of the drill bit 2 side surfaces parts that rub are outside thread.
The connecting ring 5 of the present embodiment adopts PE material, and connecting ring 5 one end are welded and fixed with new pipe 4, and the other end and drill bit 2 are welded and fixed.Lay and will newly manage 3 after putting in place and disconnect and complete pipeline and change with connecting ring 5 at new pipe.
Drill bit only needs to follow drilling rod rotation, and drill bit 2 can be connected or keyway connection by buckle with drilling rod 1.
Change for the pipeline that adapts to various calibers, drill bit 2 end faces of the present embodiment are rounded, diameter range 160mm～200mm.Change efficiency for improving, drilling rod 1 tail end is provided with the power plant (not shown) for rotation traction traction drilling rod.
embodiment two
Shown in Fig. 2, the present embodiment and embodiment's one difference are: the increasing of the drill bit 2 side surfaces parts that rub are the cutting fin 2B being arranged on drill bit side surface, and cutting fin 2B end has cutting inclined-plane.Drill bit 2 is Rotational Symmetry shape, and cutting fin 2B and bus are inclination angle and arrange, and to improve cutting rate, saves the replacing time.
