Abstract

The invention discloses a kind of pipeline restorative procedures, prepare the lining form for repairing pipeline first, and lining form is cylindrical, and the diameter of lining form is not less than pipeline interior diameter, and the length of lining form is not less than the length of pipeline to be repaired；Secondly the both ends of pipeline to be repaired are exposed, one end of pipeline to be repaired is connect with bend pipe, a circle circle mouth of cylinder-shaped lining form is clamped between pipeline and bend pipe；Then it pours water between lining form and bend pipe, lining form extends up to the other end for reaching pipeline to pipeline depths in the presence of hydraulic pressure；The ponding in lining form is finally exhausted, trims and fixes lining form, restore pipeline again, complete pipeline reparation.Pipeline restorative procedure of the invention is voluntarily extended along pipeline using hydraulic drives lining form, repair process without digging out all pipelines, without checking specific leak source, greatly reduce the project amount of construction, significantly reduce the cost of pipeline reparation.

Description

Pipeline restorative procedure

Technical field

The present invention relates to pipeline maintenance area more particularly to a kind of methods for repairing pipeline using lining form.

Background technique

All kinds of pipelines such as tap water pipe line, heating pipeline are easy to generate leak source because of corrosion after permanent use, These leak sources are small and scattered, and the position that leak source occurs can also be followed without rule, it is very difficult to investigation and reparation.It is in most cases Exclude the leakage of pipeline, maintaining unit can only large area replace pipeline, construction volume is huge；Sometimes have above old pipeline It is largely difficult to the facility removed, maintaining unit is even directly laid with new pipeline and replaces old pipeline；Although these methods can Solve the problems, such as leakage, but it is with high costs.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of pipeline restorative procedures, utilize the interior table of lining form covering pipeline Face reduces pipeline rehabilitation cost without checking specific leak source position.

In order to solve the above technical problems, the technical solution adopted by the present invention are as follows: a kind of pipeline restorative procedure, including walk as follows It is rapid:

Step 1: preparing the lining form for repairing pipeline, lining form is cylindrical, and the diameter of lining form is not less than pipeline interior diameter (under normal circumstances, guaranteeing that lining form diameter is equal to pipeline interior diameter), the length of lining form is not less than the length of pipeline to be repaired Degree；TPU film may be selected in lining form；

Step 2: the both ends of pipeline to be repaired being exposed, if to be repaired is underground running water pipe, originally It excavates the position at water pipe both ends；

Step 3: one end of pipeline to be repaired is connect with bend pipe；

Step 4: a circle circle mouth of cylinder-shaped lining form is clamped between pipeline and bend pipe；

Step 5: pouring water between lining form and bend pipe, lining form extends up to arrival pipe to pipeline depths in the presence of hydraulic pressure The other end on road；

Step 6: exhausting the ponding in lining form, trim and fix lining form, restore pipeline again, complete pipeline reparation.

In order to improve the laminating degree of lining form and pipeline inner wall, in the step 5, sprayed in pipeline inner wall to be repaired Binder.

In order to consolidate pipeline repairing effect, step 4-6 can also be repeated several times, in channel interior place mat multilayer lining form, phase Answer, can also between lining form and lining form spraying adhesive.

Further, the pipeline end and bend pipe end are respectively provided with flange, and pipeline and bend pipe pass through flanged joint.

Further, carry out spraying adhesive using spraying trolley, be provided with lighting apparatus and camera shooting on the spraying trolley Machine, trolley shoot the specific image of channel interior while spraying, maintaining unit are helped further specifically to understand showing for pipeline Shape.

The utility model has the advantages that pipeline restorative procedure of the invention is voluntarily extended along pipeline using hydraulic drives lining form, repaired Cheng Wuxu digs out all pipelines, without checking specific leak source, greatly reduces the project amount of construction, significantly reduces pipeline and repair Multiple cost.

Detailed description of the invention

Fig. 1 is 1 pipeline repair process schematic diagram of embodiment.

Wherein: 1, pipeline；2, lining form；3, bend pipe；4, flange；5, trolley is sprayed.

Specific embodiment

Invention is further described in detail With reference to embodiment.

Embodiment 1

As shown in Figure 1, the pipeline restorative procedure of the present embodiment mainly includes walking as follows when descending tap water pipe line in repair It is rapid:

Step 1: preparing the lining form 2 (TPU film) for repairing pipeline 1, lining form 2 is cylindrical, and the diameter of lining form 2 is equal to 1 interior diameter of pipeline, the length of lining form 2 are not less than the length of pipeline 1 to be repaired；

Step 2: the both ends of tap water pipe line 1 to be repaired are excavated, the both ends of pipeline 1 to be repaired are sudden and violent Dew；

Step 3: spraying trolley 5 being placed in pipeline 1, remote spraying trolley 5 is to 1 inner-wall spraying binder of pipeline；Simultaneously Utilize the video of lighting apparatus and video camera shooting 1 inner wall of pipeline on spraying trolley 5；

Step 4: one end welded flange 4 of pipeline 1 to be repaired will be to be repaired in one end welded flange 4 of bend pipe 3 One end and the bend pipe 3 of pipeline 1 connect by flange 4, the open end of bend pipe 3 is upward；While connection, by cylinder-shaped lining form A 2 circle circle mouth is clamped between pipeline 1 and bend pipe 3, and sealing ring is arranged between flange 4 and lining form 2, guarantees pipeline 1 and bend pipe 3 The circle mouth of lining form 2 is tightly clamped in centre；

Step 5: pouring water into lining form 2 and bend pipe, lining form 2 extends up to arrival to 1 depths of pipeline in the presence of hydraulic pressure The other end of pipeline 1；If the length of lining form 2 is less than twice of 1 length of pipeline to be repaired, the end of lining form 2 will enter pipe Road 1 means such as needs to tie up the end use of lining form 2 at this time and seals；If the length of lining form 2 is greater than pipe to be repaired Twice of 1 length of road, then without carrying out sealing treatment to lining form 2；

Step 6: exhausting the ponding in lining form 2, trim and fix lining form 2, recycle extra lining form 2, restore pipeline again 1, it completes pipeline 1 and repairs.

If necessary to multilayer lining form 2 is inserted in pipeline 1, then repeat step 3 to step 6.

Although embodiments of the present invention are illustrated in specification, these embodiments are intended only as prompting, It should not limit protection scope of the present invention.It is equal that various omission, substitution, and alteration are carried out without departing from the spirit and scope of the present invention It should be included within the scope of the present invention.
