The beneficial effects of the present invention are:
1, helical blade is designed on cable, cable is not only convenient for and is easily transported in pipeline, and can conveyed
While plugging particle is filled into pipeline, realize a step, simultaneously in place；In addition, the design of helical blade also plays cable
To the effect of support, also just because of the design of helical blade avoids inner wall of the pipe to the friction damage of cable, solve from the root
The problem of cable insulation of having determined is damaged and influences insulation performance.
2, blade tip cross section is the friction that circular design can reduce helical blade and inner wall of the pipe, reduces conveying resistance
Power improves transfer efficiency, guarantees that cable is light, quick, intact and is transported in pipeline.
3, by long-term research, the ratio between the thickness L of blade root and the diameter D of blade tip are designed as 1:(1-1.2 by us), both
It ensure that the support strength to cable；The reduction driving force of maximizing again, reduces the power of horizontal drill, extends horizontal electric drill
Service life；It also ensures that plugging particle is gathered in the end of cable, is stacked on together, guarantee that plugging particle is closely knit and fill out
It fills between pipeline and cable.
4, the ratio between internal diameter of the outer diameter of helical blade and pipeline is the design of 0.8:1, on the one hand can guarantee helical blade
Pipeline can easily be entered with cable, reduce the friction with inner wall of the pipe, reduce transporting resistance；On the other hand the Proportionality design
During helical feed, it is ensured that plugging particle is accurately transported to target position by spiral thrust, the resistance with disk
Gear effect has combined the filling sealing of twin conduit；The supporting role to cable can also be further increased, is set based on this
Meter, we are by 3-5 times of the difference that the input amount of plugging particle is pipe diameter and cable size, the blocking put into this way
Grain, can reach it is good to the fixed function of cable in pipeline while, also advanced optimized the dosage of plugging particle,
It saves function material-saving and fixed function is best.
5, the two ends of helical blade are disk, and the ratio between internal diameter of the diameter of disk and pipeline is (0.8-0.9): 1,
Should designed for prevent plugging particle during helical feed overflow, outside escape to cable socket, guarantee that plugging particle can
To be assembled, be stacked into target position, in conjunction with the filling sealing for having designed twin conduit of helical blade.
6, on the one hand the setting of disk periphery hairbrush circle further prevents plugging particle to overflow during helical feed
Outside stream, escape to cable socket；On the other hand for clearing up the sundries in pipeline, avoid sundries in pipeline that cable transfer is caused to hinder
The increase of power avoids sundries in pipeline from causing to damage to cable.
7, by long-term research, packing material is prepared into graininess by us, by the structure of helical blade, with cable
The drawbacks of synchronizing in place, avoiding later period addition packing material.In the course of the study, we encounter following problem: due to
Packing material is graininess, 1. how by plugging particle conveying, be deposited in cable socket needs solve；2. how will blocking
Particle it is closely knit be deposited in cable socket, be filled between cable and pipeline need solve.The solution of problem 1. realizes
By plugging particle conveying, it is deposited in cable socket, but the problem of there is also leakproofness, the solution of problem 2. is realized with blocking
Particle seals the filling of underground cable, the two combine realize by plugging particle it is closely knit be deposited in cable socket.It is above-mentioned

Under cold low temperature environment, cold air is avoided to enter in pipeline, cable is caused to freeze and is lost；Pass through EPDMK8340A, magnesia, tristearin
The plugging particle that acid, lubricating oil, calcium oxide, TMTD promotor are compounded with medicinal material guarantees that cable is in one always
Stable environment is avoided because environmental change, temperature fluctuations are chronic injury and persecution caused by cable.
9, with walking mechanism and the design of support frame that is set between drilling rod and pipeline is between drilling rod and pipeline
Cable plays support and guiding role, and avoiding cable because causing helical blade from recurrence is sagging and bending, deformation occurs and defeated
Difficulty, resistance is sent to increase.The design of cable trough prevents cable from deviating from, and has position-limiting action, and beaming roller plays support to cable and leads
To effect, have certain facilitation to the conveying of cable.
10, by long-term research, we break conventional straight line handling cable mode, abandoned stretch the meaning, straight line
The inertial thinking of dragging, looks for another way, and proposes curve handling cable mode, substantially increases cable transfer rate, reduces
Cable transfer difficulty also solves support, positioning, wear problem of the cable in pipeline.By cable transfer mode by straight line
Conveying is changed to the improvement of curve conveying, needs to solve how to fill packing material to pipeline.The mode of conventional linear conveying
It is packing material to be filled in into pipeline, but this filling mode is obviously not suitable for song of the invention after the completion of cable transfer
Line conveying, cannot achieve filling and sealing, thus, it studies and a kind of filling mode of the invention is suitble to be us in innovation into curve
Problem to be solved after handling cable mode, packing material is prepared into graininess, passed through by us by further research
The structure of helical blade in place with cable synchronizing not only solves the above problem, it is thus also avoided that the disadvantage of later period addition packing material
