Description
Technical field
It the utility model is related to pipe rehabilitation technology field, more particularly to a kind of eight leaf liner templates.
Background technology
The reparation of underground utilities at present has a variety of methods, such as：1st, convention liner method.This method is that a diameter is slightly smaller
New tube body directly include or pull in and hold in the tube body of reparation, then the annular gap between Xiang Xinguan and tube body to be repaired fills
Slurry, is that new tube body is consolidated with tube body to be repaired after grout cures, completes the reparation of tube body to be repaired.2nd, high density polyethylene (HDPE) pressure
U Insertion methods.High density polyethylene (HDPE) pressure U Insertion methods be before construction by new tube body (mainly polyethylene pipe) by mechanical processing,
Its section is deformed, is then sent to hold and repairs in tube body, then by heating pressurization or making its extensive by operation of nature
Original shape and size are arrived again, so as to form close cooperation with tube body to be repaired, complete the reparation of tube body to be repaired.3rd, turn over
Turn Internal Lining Method.This method uses the pipeline inner case to be repaired of closed-circuit TV camera inspection, and when construction will contain heat setting tree
The flexible textile pipe of fat is pulled in from people's well or other working pits by winch, liquid or gas pressure can also be utilized to push into desire
In the pipeline of reparation, spinnerule is close to inboard wall of tube body to be repaired under the action of hydraulic pressure or air pressure, complete tube body to be repaired
Repair.4th, spiral winding method.This method is mainly used for repairing sewage conduct.During construction, by means of spiral winding machine, the bar of interlocking
Band is wound in a continuous tubular liner layer in tube body to be repaired, so as to complete the reparation of tube body to be repaired.5th, spraying process.
This method is mainly used for the preservative treatment of pipeline, and the nozzle of revolution at a high speed is returned under the traction of winch, behind one side while by cement
Slurries or epoxy resin are equably sprayed on the inner wall of pipeline, reach the effect of tube body reparation.6th, local route repair method.Part is repaiied
Compound method is very much, mainly including Sealing Method, patch method, grouting method, dumpling connection, robot method etc..
The foregoing various restorative procedures to underground utilities, although being attained by the effect of tube body reparation, also all exist
Need improved space, such as high density polyethylene (HDPE) pressure U Insertion methods, the high ring rigidity used during reparation it is different in nature highly dense
Spend polyethylene liner template, although can site welding, by professional equipment be pressed into it is U-shaped after can complete the entirety of pipeline to be repaired
It is interspersed, but since the structural stability of high density polyethylene (HDPE) template tube wall is unable to reach the high ring rigidity requirement of load-bearing pipeline,
Reach high ring rigidity requirement, then need increase high density polyethylene pipe wall thickness, be about further added by the basis of origianl wall thickness 6 to
7 times, so not only former bore can be greatly reduced, also add material cost and site operation engineering cost, therefore have
Pending improvement.
