Abstract
The utility model relates to a tap type tool pipe for pipe jacking machines, which comprises a pipe body (1) of a knife-edge pipe. The utility model is characterized in that the inner wall around the pipe body (1) of a knife-edge pipe is provided with at least three connecting lugs (10), each of which is provided with a regulating screw rod (2) which is extended backwards along a pipeline shaft and used for connecting a jacking pipeline (9) through a regulating nut; the back end of the pipe body (1) of a knife-edge pipe is provided with an annular mud chamber (4) around the regulating screw rod; the front side wall of the mud chamber is provided with a mud charging hole (3) which is communicated with the mud chamber, and the back side wall is provided with a plurality of mud outlet holes (5) with the method of uniform distribution. The utility model has the advantages of simple structure, easy disassembly and assembly and convenient operation. The height and middle line deflection in the process of pipeline jacking can be regulated in time effectively by the regulating screw rod at any time, and the thixotropy mud can be pressurized and conveyed between the outer wall of the jacked pipeline and soil for reducing the frictional force of the outer wall of the jacked pipeline and the soil.
Description
Technical field
The utility model relates to underground pipeline construction equipment, relates to a kind of silk pushing-type tool pipe that is used for push-bench specifically.
Background technique
Along with the continuous development of under ground piping non-excavation laying construction technology, one of the most common method of construction when pipe-jacking technology has become pipeline and passes through ground obstacle.In the construction of existing pipe-jacking technology, the tool pipe that is used for push-bench can be divided into closed and two kinds of open types according to opening form.Though the tool pipe of above-mentioned two kinds of structures is each has something to recommend him in actual use, all exist the practical problem that complex structure, dismounting difficulty, complex operation, technical specifications are had relatively high expectations.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy disassembling, easy and simple to handle, technical specifications to require the lower silk pushing-type tool pipe that is used for push-bench just at existing deficiency in the above-mentioned prior art.
The purpose of this utility model can realize by following measure:
The silk pushing-type tool pipe that is used for push-bench of the present utility model comprises cutting edge pipe body, be provided with at least three engaging lugs around cutting edge pipe inboard wall of tube body, on each engaging lug, an adjusting screw rod that is used to connect the jacking pipeline that extends back along pipeline axial be installed by adjusting nut; Be provided with an annular mud storehouse in cutting edge pipe body rear end, the front panel in this mud storehouse is provided with the mud filler port in a connection mud storehouse, in uniform mode a plurality of slurry outlets is set on its rear sidewall.
Adjustment for ease of pipeline jacking direction, angle, the utility model is being evenly equipped with four engaging lugs around cutting edge pipe inboard wall of tube body, by adjusting nut an adjusting screw rod that is used to connect the jacking pipeline that extends back along pipeline axial is installed on each engaging lug.
For ease of the coating of mud in the jacking, the internal ring wall in described mud storehouse is provided with the mud coating section that a level extends back.
Working principle of the present utility model is as follows:
At first the utility model tool pipe is connected on the jacking pipeline by adjusting screw rod, and makes tool pipe and jacking pipeline keep coaxial line to combine by adjusting nut.After the beginning jacking, elevation and center line that every jacking 50cm promptly tackles pipeline carry out the one-shot measurement inspection, when finding that pipeline has off-design track phenomenon, just can in time rectify a deviation to the angle between tool pipe and the jacking pipeline by adjusting nut.After tool pipe all buries, just can thixotropic slurry be joined the mud storehouse by being positioned at the mud filler port that is provided with on the front panel of tool pipe mud storehouse, and mud evenly is depressed between the outer wall and soil of jacking pipeline by a plurality of slurry outlets uniform on the rear side ring wall of mud storehouse, make to form one deck thixotropic slurry lubricating layer between jacking pipeline outer wall and the soil, in order to reduce the frictional force between jacking pipeline outer wall and the soil.
That the utility model not only has is simple in structure, easy disassembling, easy and simple to handle, technical specifications require lower advantage, also can be by adjusting screw rod at any time effectively to the adjustment of rectifying a deviation timely of contingent elevation and medium line error thereof in the pipeline jack-in process, and can be with the thixotropic slurry pressurized delivered extremely by between the outer wall of jacking pipeline and the soil, between by jacking pipeline outer wall and soil, form one deck thixotropic slurry lubricating layer, in order to reduce by the frictional force between jacking pipeline outer wall and the soil.
