Abstract

The utility model discloses the inside and outside prosthetic device simultaneously of a kind of pipeline, including 2 aerating gasbags, 2 aerating gasbags are connected with each other, and closely fit with pipeline after airbag aeration, to be repaired section of pipeline is made to become a complete confined space, dispose slip casting shower nozzle in air bag centre position, repair serosity and by slip casting shower nozzle, reparation serosity is extruded to leak source under pressure.The purpose of this utility model is to provide a kind of device without just can be realized pipeline rehabilitation by excavation renewal local pipe.

Description

The inside and outside prosthetic device simultaneously of a kind of pipeline

Technical field

This utility model relates to pipeline rehabilitation field, is specifically related to the inside and outside prosthetic device simultaneously of a kind of pipeline.

Background technology

The most conventional pipe rehabilitation technology mainly has Internal Lining Method, soft lining method, winding method, spraying process and grouting method.Existing The reparation of method is and partially or completely uses new tubing to substitute or the pipeline at the original position of reinforcement.In work progress still Needing to carry out local excavation, renovation technique is complicated.

Summary of the invention

The purpose of this utility model is to provide a kind of without just being realized inside and outside pipeline by excavation renewal local pipe Prosthetic device simultaneously.

In order to achieve the above object, this utility model has a following technical scheme:

The inside and outside prosthetic device simultaneously of a kind of pipeline, including 2 aerating gasbags, 2 aerating gasbags are connected with each other, airbag aeration Closely fit with pipeline afterwards, make to be repaired section of pipeline become a complete confined space, repair solution at confined space intrinsic pressure The lower extruding of effect is to leak source and pipeline external.

Further, repair solution and constituted by no less than the material of two components, before different component mixing, keep liquid, Upon mixing can be with fast setting.

Further, it is water miscible for repairing solution.

Further, the reparation solution of each component is less than 3 minutes mixed hardening time.

Owing to taking above technical scheme, the utility model has the advantage of:

Use of the present utility model avoids civil plantation impact big, and rehabilitation cost is high, difficulty is big, motility is not enough Problem；Pipeline after reparation stops pipeline to External leakage, stops outside liquid to leak into pipe interior simultaneously.After reparation, slurry Liquid firm parcel underlying surface soil, stops little hidden danger to develop, road cavity is greatly decreased and caves in；Locally many leak sources in confined space Repair 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.

In figure: 1-air bag a 2-air bag b 3-steel pipe 4-pipeline 5-Pipeline Leakage Point 6-pipeline external 7-grouting pipe and rifle.

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, the inside and outside prosthetic device simultaneously of a kind of pipeline, including 2 aerating gasbags, respectively air bag a 1, gas 2,2 aerating gasbags of capsule b are connected with each other by steel pipe 3.

Before arriving area to be repaired, air bag a 1, air bag b 2 are unsaturated inflated condition, and its outside dimension is less than pipeline 4 Internal diameter, steel pipe 3 is smaller in size than pipeline 4 internal diameter, it is simple in pipeline 4, conveniently moving arrives region to be repaired.To be repaired arriving Behind region, air bag a 1, air bag b 2 location lay respectively at the both sides of Pipeline Leakage Point 5, and air bag a 1, air bag b 2 start to fill Gas, and make air bag and pipeline 4 laminating the most closely so that duct section residing for Pipeline Leakage Point 5 is complete confined space.Repair slurry Liquid is injected in the confined space that air bag a 1, air bag b 2, steel pipe 3 and pipeline 4 are formed by grouting pipe and rifle head 7.Note Slip casting is stopped after entering the serosity of specified amount.The serosity injected in confined space under the effect of the pressure can be along Pipeline Leakage Point 5 Leak out to outside pipeline 4.After reaching the hardening time set, grout curing at Pipeline Leakage Point 5, at pipeline external 6, clay and slurry Liquid combines solidification, one protective layer of whole formation.Subsequently, air bag a 1, air bag b 2 exit, air bag a 1, air bag b 2 and pipeline 4 Separate, remove whole prosthetic device, complete to repair.

Serosity is water miscible, can be quick-setting, can be combined solidification with clay, can solidify with pipeline adhesion.

Obviously, above-described embodiment of the present utility model is only for clearly demonstrating this utility model example, and It it is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above On the basis of can also make other changes in different forms.Here cannot all of embodiment be given exhaustive. Every belong to obvious change or variation that the technical solution of the utility model extended out still in of the present utility model The row of protection domain.
