Abstract
The utility model provides a dual-channel slurry jetting device. The dual-channel slurry jetting device comprises a drill rod mechanism and a reamer mechanism, wherein the reamer mechanism is arranged in the middle of the drill rod mechanism; a slurry injection tube, a rotating joint and a drill rod are arranged symmetrically from the outer end of the drill rod mechanism; one end of the slurry injection tube is provided with a slurry injection hole, and the other end of the slurry injection tube is connected with the drill rod through the rotating joint; the reamer mechanism comprises reaming wheels, a slurry jetting hole and a reamer bracket; the reamer bracket is fixed to the drill rod; a plurality of reaming wheels are uniformly arranged on the reamer bracket; the slurry jetting hole is positioned between two adjacent reaming wheels, and is communicated with the drill rod. The dual-channel slurry jetting device has the beneficial effects that slurry is injected into the two ends in a reaming process, thereby achieving higher power and higher construction speed. The dual-channel slurry jetting device has the advantages of simple structure, convenience in maintenance, low machining cost, convenience in detachment and the like.
Description
Technical field
The utility model belongs to Constructions of No Dig Installation of Pipelines engineering field, especially relates to a kind of twin-channel slurry ejector.
Background technology
At non-excavation, pass through in engineering, when carrying out reaming, utilize mud mixing system that the mixed liquor that is mixed with mud is injected to drilling rod by mud ascending pipe, by the rotation of mud jet, be sprayed on equably on hole wall, in larger reaming engineering, one-sided drilling rod is noted into slurry power deficiency, exists reaming speed slow, affects the technical problems such as construction speed.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to use, twin-channel slurry ejector of improving speed of application, is especially applicable to the larger reaming engineering of power demand.
The technical solution of the utility model is: a kind of twin-channel slurry ejector, comprise drill rod mechanism and reamer mechanism, in the middle of described drill rod mechanism, be provided with reamer mechanism, drill rod mechanism is arranged with mud ascending pipe successively from outer end, swivel joint, drilling rod, described mud ascending pipe one end is mud inlet, the other end is connected with drilling rod by swivel joint, described reamer mechanism comprises reaming wheel, mud jet, hole expander rack, described hole expander rack is fixed on drilling rod, on hole expander rack, be evenly provided with some reaming wheels, described mud jet is between two adjacent reaming wheels, and communicate with drilling rod.
Further, swivel joint two ends are connected with drilling rod with one end of mud ascending pipe respectively by screw thread.
Further, described hole expander rack is welded on drilling rod.
Further, the number of described reaming wheel is three.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, in reaming process, mud is injected at two ends, and power is larger, and speed of application is faster; There is the advantages such as simple in structure, easy to maintenance, processing cost is low, convenient disassembly.

The specific embodiment
As shown in Figure 1,
The technical solution of the utility model is: a kind of twin-channel slurry ejector, comprise drill rod mechanism and reamer mechanism, in the middle of described drill rod mechanism, be provided with reamer mechanism, drill rod mechanism is arranged with mud ascending pipe 1 successively from outer end, swivel joint 2, drilling rod 3, described mud ascending pipe 1 one end is mud inlet, the other end is connected with drilling rod 3 by swivel joint 2, described reamer mechanism comprises reaming wheel 4, mud jet 5, hole expander rack 6, described hole expander rack 6 is fixed on drilling rod 3, on hole expander rack 6, be evenly provided with some reaming wheels 4, described mud jet 5 is between two adjacent reaming wheels 4, and communicate with drilling rod 3.
In the present embodiment, swivel joint 2 two ends are connected with drilling rod 3 with one end of mud ascending pipe 1 respectively by screw thread, and described hole expander rack 6 is welded on drilling rod 3, and the number of described reaming wheel 4 is three.
The course of work of this example: mud is injected to mud by mud ascending pipe 1, mud sprays to reaming wheel 4 from mud jet 5 through drilling rod 3, and in reaming process, bilateral injects mud and plays better cooling, lubricated reaming wheel, carries chip, stablizes hole wall effect.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
