Brief description of the drawings
Fig. 1 is the structural representation of pipe renovating system of the present invention；
Fig. 2 is the schematic flow sheet of pipe repairing method of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to specification text
Word can be implemented according to this.
As shown in figure 1, pipe renovating system of the present invention, for being entered using high density polyethylene pipe to problem pipeline
Row is repaired, i.e., by laying high density polyethylene pipe in problem pipeline and replacing damage using the high density polyethylene pipe
The problem of pipeline, the reparation to problem pipeline is realized with this.
Specifically, heretofore described pipe renovating system includes undergauge mechanism, drawing mechanism and tube mechanism.
Wherein, the undergauge mechanism is suppressed the high density polyethylene pipe to reduce the straight of high density polyethylene pipe
Footpath.The undergauge mechanism suppresses U-shaped groove vertically at the top of the high density polyethylene pipe, to make the high-density polyethylene
The diameter of alkene pipe is reduced into the 2/3 of initial diameter.In order to prevent through reducing diameter processing high density polyethylene pipe reset or
Person is deformed upon, and binding mechanism, the height that the binding mechanism will be handled by reducing diameter are also further provided with the present invention
Density polyethylene pipe along the circumferential direction bundled fixed, so that follow-up drawing mechanism is drawn.
The drawing mechanism then will be drawn across described problem pipeline by the high density polyethylene pipe for reducing diameter processing.
Before being drawn, problem pipeline need to be cleaned and repaired, to make the problem of described to be repaired pipeline flat smooth.And
When being drawn, also nontoxic lubricant grease can be smeared by the port of the pipeline to be repaired the problem of, in favor of the diminution
The high density polyethylene pipe of diameter processing is drawn across the problem of to be repaired pipeline.
The tube mechanism carries out tube to the high density polyethylene pipe through described problem pipeline, to make reduced diameter
The diameter of the high density polyethylene pipe of processing recovers to initial diameter.That is, in the high density of the diminution diameter processing
Polyethylene pipe is drawn across after the problem of to be repaired pipeline, it is necessary to make high density polyethylene pipe recover to initial diameter, with order
Its outer wall can press close to the inwall of problem pipeline, so as to more preferable pressure-bearing.So, in specific operation, the tube
(or liquid filling body) is inflated in the high density polyethylene pipe that mechanism is handled to both ends by the reduced diameter of Seal treatment, with order
The diameter of the high density polyethylene pipe recovers to initial diameter.
Pipe renovating system construction volume of the present invention is small, and short time limit is easy for construction, can be rapidly completed problem pipeline
Reparation.
The present invention also provides a kind of method that pipeline rehabilitation is carried out using foregoing pipe renovating system, as shown in Fig. 2 bag
Include following steps：
Step 101, high density polyethylene pipe is suppressed to reduce the diameter of high density polyethylene pipe to preset range.
In this step, U-shaped groove is suppressed vertically at the top of the high density polyethylene pipe, to make the high density
The diameter of polyethylene pipe reduces, and as a rule, the diameter of high density polyethylene pipe is reduced into initial diameter 2/3 can meet
The reparation requirement at scene.Due to it is to be repaired the problem of pipeline length be not quite similar, suppressed to high density polyethylene pipe
Before reducing the diameter of high density polyethylene pipe, some high density polyethylene pipes first can be carried out into head and the tail welding, to obtain
With it is to be repaired the problem of the corresponding high density polyethylene pipe of duct length, then carry out unified compacting again.In order to prevent through
Cross the high density polyethylene pipe reset for reducing diameter processing or deform upon, the step 101 further comprises, to passing through
The high density polyethylene pipe along the circumferential direction bundled fixed of diameter processing is reduced, is had by the high density polyethylene pipe of bundled fixed
Beneficial to follow-up traction process.
It should be noted that the problem of to be repaired pipeline generally there are scale formation, need to enter problem pipeline before reparation
Row cleaning and repairing, remove discarded object therein, including hydrocarbon, corrosive deposit and mixed and disorderly substances in pipe etc..In addition, also needing pair
Repaired at the defects of problem pipeline, to make the problem of described to be repaired pipeline flat smooth.Specifically, to problem pipeline
Cleaning should accomplish to make problem pipeline without obvious attachment and without sharp burrs.In addition, for the protrusion in problem pipeline and
Wedge angle, to be cleaned multiple times, until its sharp corners is ground off, make its smooth；For the interface faulting of slab ends more than pipe diameter 8%,
Gap location will be cleaned first, then take cement mortar (addition adhesive) floating processing, to make mend smooth；For compared with macroscopic-void
The repairing of fault location, need to be according to fault location concrete condition, and scene determines outside or inside mending option.
Step 102, the problem of to be repaired pipeline will be drawn across by the high density polyethylene pipe for reducing diameter processing.
In this step, directive wheel can be installed in the mouth of pipe of problem pipeline, to prevent mouth of pipe corner angle from scratching high density polyethylene (HDPE)
Manage and cause to damage, also can effectively prevent high density polyethylene pipe from going out overlapping pleating in the mouth of pipe of problem pipeline.In addition, can also be
The problem of to be repaired, the port of pipeline smeared the high density polyethylene pipe of nontoxic lubricant grease in favor of the diminution diameter processing
It is drawn across the problem of to be repaired pipeline.
Step 103, tube is carried out to the high density polyethylene pipe through described problem pipeline, to make reduced diameter processing
The diameter of high density polyethylene pipe recover to initial diameter.
In this step, the port of the high density polyethylene pipe of reduced diameter processing can be held round first with air bag；
Flange is integrally formed out at the port again, the flange is connected to form composite flange with metal flange；
The composite flange is blocked with metal blind plate, and inflation tube in backward high density polyethylene pipe.
, specifically can be intact for intact pipeline and the connected mode for repairing high density polyethylene pipe used in filling
The end of pipeline corresponding bump joint is installed, then linked together with foregoing composite flange and form the pipeline of conducting.
Pipe repairing method of the present invention has substantially no effect on traffic above pipeline, road, building, both meets
It bearing requirements, in turn ensure that pipeline is unimpeded, there is great promotional value.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, it is of the invention and unlimited
In specific details and shown here as the legend with description.
