Abstract
The utility model discloses a local auxiliary device that restores of pipeline, including 3 the airbag, 3 the airbag interconnect, wherein, left side the airbag and right side the airbag inflate the back and laminate closely with the pipeline, make the pipeline wait to repair a duan chengyi complete airtight space, and middle the airbag pushes the restoration thick liquid to the leak source through constantly inflating. The utility model aims at providing a need not to update local pipeline alright supplementary prosthetic devices in order to realize pipeline rehabilitation through the excavation.
Description
Technical field
This utility model relates to pipeline rehabilitation field, is specifically related to a kind of pipeline local route repair auxiliary device.
Background technology
Pipe rehabilitation technology conventional at present mainly has Internal Lining Method, soft lining method, winding method, spraying process and grouting method. Existing methodical reparation is the pipeline partially or completely using new tubing replacement or the original position of reinforcement. Remaining a need for carrying out local excavation in work progress, renovation technique is complicated.
Utility model content
The purpose of this utility model is to provide a kind of auxiliary prosthetic device that just can realize pipeline rehabilitation without passing through excavation renewal local pipe.
In order to achieve the above object, this utility model has following technical scheme:
A kind of pipeline local route repair auxiliary device, including 3 aerating gasbags, 3 aerating gasbags are connected with each other, wherein, closely fit with pipeline after left side aerating gasbag and the inflation of right side aerating gasbag, making to be repaired section of pipeline become a complete confined space, reparation serosity is squeezed to leak source by constantly inflation by middle aerating gasbag.
Further, described aerating gasbag outer surface is etch resistant layer.
Further, described aerating gasbag outside dimension is less than internal diameter of the pipeline.
Owing to taking above technical scheme, the utility model has the advantage of:
Use of the present utility model avoids civil plantation impact big, the problem that rehabilitation cost is high, difficulty is big, motility is not enough; Pipeline after reparation stops pipeline to External leakage, stops outside liquid to leak into pipe interior simultaneously. After reparation, serosity firm parcel underlying surface soil, stop little hidden danger to develop, road cavity is greatly decreased and caves in; In the confined space of local, many leak sources are repaired simultaneously, and it is notable that arm connects gap leakage reparation usefulness.
Accompanying drawing explanation
Fig. 1 is this utility model prosthetic device structural representation.

Detailed description of the invention
Hereinafter implement to be used for illustrating this utility model, but be not limited to scope of the present utility model.
Shown in Figure 1, a kind of pipeline local route repair auxiliary device, including 3 aerating gasbags, respectively air bag a1, air bag b2, air bag c3,3 aerating gasbags are connected with each other.
Before arriving area to be repaired, air bag a1, air bag b2, air bag c3 are unsaturated inflated condition, and its outside dimension is less than pipeline 4 internal diameter, it is simple in pipeline 4, conveniently moving arrives region to be repaired.After arriving region to be repaired, air bag a1, air bag b2 location lay respectively at the both sides of Pipeline Leakage Point 5, and air bag a1, air bag b2 start inflation, and make air bag and pipeline 4 laminating completely closely so that duct section residing for Pipeline Leakage Point 5 is complete confined space. Then air bag c3 starts inflation, and serosity is injected in the confined space that air bag a1, air bag b2, air bag c3 and pipeline 4 are formed by grouting pipe and rifle head 7 simultaneously. Slip casting is stopped after injecting the serosity of specified amount. Air bag c3 continues for inflation, and air bag c3 and pipeline 4 are fitted completely. The serosity before injected in confined space can along outside Pipeline Leakage Point 5 leaks out to pipeline 4. After reaching the hardening time set, Pipeline Leakage Point 5 place is grout curing, and at pipeline external 6, clay is combined solidification, one protective layer of whole formation with serosity. Subsequently, air bag a1, air bag b2, air bag c3 exit, and air bag a1, air bag b2, air bag c3 separate with pipeline 4, remove whole prosthetic device, complete to repair.
Serosity is water miscible, it is possible to quick-setting, it is possible to be combined solidification with clay, it is possible to solidify with pipeline adhesion.
Obviously, above-described embodiment of the present utility model is only for clearly demonstrating this utility model example, and is not the restriction to embodiment of the present utility model. For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description. Here cannot all of embodiment be given exhaustive. Every belong to apparent change that the technical solution of the utility model extended out or the variation row still in protection domain of the present utility model.
