Abstract
The utility model relates to a built-up pipeline repairing device by a lining-turnover method, which is used for enforcing lining-turnover technology for repairing the underground pipeline without excavating. The utility model comprises a container, an adjustable lining-turnover device, a guide elbow, a pressure meter, a flaring positioner, etc. Through the container, the lining-turnover device, the guide elbow, and the flaring positioner, a flexible pipe of a composite structure which is dipped by polymer utilizes water or air as motive power; the turnover lining of the composite flexible pipe is caused to enter the internal part of the pipe which needs to be repaired; through normal temperature or thermosetting, a pipe sleeved with a pipe which has smooth internal surface and high and strong rigidity can be formed. The built-up pipeline repairing device by a lining-turnover method is convenient for field removal and assembly of cities; according to requirements, lining angles can be optionally adjusted; air-tight performance of the pipe sleeved with a pipe can be greatly increased, and influence of artificial factors on engineering quality can be avoided.
Description
The utility model belongs to the reparation underground utility, implements not excavate ground, turns over on-the-spot constructing device one assembly type of using of lining method reparation and turns over lining method pipeline repairing device
Original lining device that turns over adopts tower device, during construction when operation, interior village layer is shape in the shape of a spiral easily, with be easy to leak with pipeline to be repaired joint, cause reinstatement works with low quality, as liner surface because shape in the shape of a spiral, and cause rough, out-of-flatness, air-tightness is poor, and the original device bulkiness, resettlement and assembling are very inconvenient, and setup time is long.
Provide a kind of assembly type order of the present utility model and turn over lining method pipeline repairing device, avoided original lining device that turns over when operation, inside liner is shape and be easy to leak with pipeline to be repaired joint in the shape of a spiral easily, cause reinstatement works with low quality, as liner surface because shape in the shape of a spiral, and cause rough, out-of-flatness, air-tightness is poor, and the original device bulkiness, resettlement and assembling are very inconvenient, the shortcoming and defect that setup time is long.
Be achieved in that order of the present utility model
A kind of assembly type is turned over lining method pipeline repairing device, it is characterized in that: the container of a circle shape, be connected with the turn-over device of circle shape angle adjustable in the bottom of container, the turn-over device below is isometrical guiding elbow, and pressure gauge, isometrical another mouthful of guiding elbow connection hole enlargement positioning work piece are housed on the isometrical guiding elbow.
The turn-over device of circle shape angle adjustable is adopted in the container bottom.
The pipeline of guiding elbow and reparation is isometrical, and the radius of curvature of guiding elbow is 0.8-1.5 a times of its caliber.The lower end of guiding elbow is the hole enlargement positioning work piece, is of a size of the 50-100 millimeter apart with mouth of pipe end face.
The utility model has been compared following advantage with original device:
1. apparatus structure is light, simple, is convenient to on-the-spot resettlement, assembling, and floor space is little, and is required
Operating pit is little.
2. the inside liner quality after pipeline is repaired is good---smooth surface, air-tightness height.
3. owing to the reasonable in design of installing, as adjustable turn-over device, isometrical guiding elbow, hole enlargement
Multiple tracks locating functions such as device have thoroughly solved the random big shortcoming in original device,
Not influenced by personal factor.
4. device is provided with pressure gauge, can quantitatively adjust according to the pressure requirement in the construction organization design.
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is that assembly type is turned over lining method pipeline repairing device schematic representation
A kind of assembly type is turned over lining method pipeline repairing device, the container of a circle shape, in the lower ports of container (1), be connected with the turn-over device (2) of circle shape angle adjustable, the turn-over device below is an isometrical guiding elbow (3), and pressure gauge (4), another mouthful of isometrical guiding elbow connection hole enlargement positioning work piece (5) are housed on the isometrical guiding elbow.The turn-over device of drum round angle adjustable is adopted in the container bottom.The pipeline of guiding elbow and reparation is isometrical, and the radius of curvature of guiding elbow is 0.8-1.5 a times of its caliber.The lower end of guiding elbow is the hole enlargement positioning work piece, is of a size of the 50-100 millimeter apart with mouth of pipe end face.
During construction with the flexible pipe of the composite structure of impregnated polymer, enter into container (1), field condition during the visual construction of container, take vertical or horizontal, as required different height can be set,, establish the turn-over device (2) of angle adjustable at the outlet of container end, so that adjust angle during the liner operation, turn over the lining location.Then, the flexible pipe of composite structure enters into isometrical guiding elbow (3), enters in the pipe through the hole enlargement positioning work piece (5) of its lower end, forms and is close to tight pipe-in-pipe.
Through the flexible pipe of the composite structure of impregnated polymer, by container (1), adjustable turn-over device (2), treat footpath lead elbow (3), pressure gauge (4) and hole enlargement positioning work piece (5).Enter in the pipe that is repaired, be close to the inwall of pipeline, through normal temperature or be heating and curing, form the pipe-in-pipe of smooth high-strength rigidity, this device is convenient to on-the-spot resettlement in city and assembling, and floor space is little, and angle is gone in the regulated at will village as required, also can improve the air-tightness of pipe-in-pipe significantly, avoid the influence of personal factor the reinstatement works quality.
Case history: assembly type is turned over lining method pipeline repairing device, cross Haihe River water-supply line at φ 760, φ 426 * 7 high pressure gas pipelines, φ 325 * 12 residual oil pipelines are used on the 20 multinomial reinstatement workss such as DN300, DN400, DN600 cast iron gas-pipe line and φ 1200 blowdown pipelines.Operational pressure is 0.02Mpa-0.15Mpa, and one-stop operation length can reach 900 meters, operating speed 1-6 rice/minute, heat curing temperature is 60-65 ℃ or normal temperature cure, the pipeline pressure-bearing after the reparation is up to 2.8Mpa.Each size of forming of device is all isometrical with pipeline.Liner surface is smooth, and the air-tightness of the pipeline after the reparation is all up to standard.
The purpose that the utility model assembly type is turned over lining method pipeline repairing device can reach by following measure: the adjustable turn-over device (2) of container (1) bottom, the regulated at will angle is adjusted angle arbitrarily to zero-bit according to on-the-spot needs as required.Spiral angle when making the flexible pipe operation is transferred to zero-bit, avoids the personal factor influence, and guiding elbow (3) is isometrical with pipeline to be repaiied, and its interface binding power is identical, has played the effect of pressure location.The hole enlargement positioning work piece (5) of the lower end of guiding elbow (3) under the effect of operational pressure, makes the composite soft tube hole enlargement, guarantees that inside liner pastes tightly mutually with the port of pipeline, has improved the air-tightness of pipe-in-pipe.
