Abstract
The utility model relates to a composite hose for repairing underground pipelines, which uses composite polyolefin of non-woven geotextile as a carrier; after polymer is dipped, the external side of the polymer is provided with one layer of composite polyolefin water-proof membrane, and the hose is provided with a hot melting sealing at the seaming point. Before solidification is conducted, the composite hose for repairing underground pipelines is made of very soft and foldable flaky materials; after water and compressed air are used as pressure sources, a turnover liner can enter the pipe, and the solidified surface is smooth and is provided with a pipe sleeved with a pipe with high strength and rigidity. The utility model has the advantages of good integrity, good air tightness, convenient construction, and reduced cost, and repaired engineering quality can be ensured to not to have hidden trouble. The utility model is suitable for gas, water supply, water drainage, and chemical medium conveying pipelines.
Description
The utility model belongs to composite soft tube, and particularly a kind of underground utility of specializing in adopt and not excavate the composite soft tube that the reparation underground utility that pipeline technology uses are repaired on ground.
Now adopt multi-layer structure with flexible pipe, multi-layer structure not only influences the integrity of operation, liner surface is folded easily, out-of-flatness has increased fabricating cost again, because existing with flexible pipe overlay layer of glass grid, make the operation elastic expansion amount of flexible pipe almost nil, be easy to and wait to repair and form hollowing between the pipeline, owing to now adopt sealer to seal, cause the air-tightness of flexible pipe to reduce significantly again with flexible pipe.More than these reasons, not only improved engineering cost, bring serious hidden danger for simultaneously the quality of reinstatement works.
The purpose of this utility model provides a kind of composite soft tube of repairing underground utility, overcomes now to adopt multi-layer structure with flexible pipe, influences the integrity of operation, and liner surface folds easily, out-of-flatness,
The cost height, operation elastic expansion amount is almost nil, is easy to and waits to repair form hollowing between the pipeline, and tightness is low, brings the shortcoming and defect of serious hidden danger simultaneously to the quality of reinstatement works.
The purpose of this utility model is achieved in that
A kind of composite soft tube of repairing underground utility is characterized in that: hose body is the pipe that the individual layer non-woven geotextile of impregnated polymer is made, and its outside is one deck compound polyolefin waterproof membrane, and the seam crossing of flexible pipe is a heat sealing.
The individual layer non-woven geotextile is an individual layer, and the fiber in the individual layer non-woven geotextile is based on polyster fibre, admixture Ti metal fiber or compound fibers such as glass fibre or polypropylene fibre, vinylon, and the swollen long rate of its construction operation elasticity of individual layer non-woven geotextile is 8-18%.Heat sealing is whole the fusion, and it seals no any solvent channel.The waterproof membrane of flexible pipe outside, it can be PVC or polyurethane material that the root tool needs.
The utility model has the advantages that:
Good integrity, tightness is good, is convenient to construction, reduces cost, and the construction quality after guaranteeing to repair does not have hidden danger.Be applicable to the pipeline that coal gas, feedwater, draining and chemical mediator are carried.
Below in conjunction with description of drawings embodiment:
Fig. 1 is a composite soft tube sectional view of repairing underground utility
Fig. 2 is composite soft tube and an interface partial enlarged drawing of repairing underground utility
The composite soft tube of repairing underground utility is through being combined into facial mask with polyolefin (2) plastics by individual layer non-woven geotextile (1), seal (3) through HF hot melt, form the good flexible pipe carrier of tightness, behind polymer (4) dipping, becoming folding sheet material, is very soft folding sheet material before curing, through water or pressurized air as pressure source, turn over lining and enter in the pipe, solidify the rear surface and be smooth pipe-in-pipe with high-strength rigidity.Go in the old pipe to be repaired at the time liner of setting, solidify to form ganoid pipe-in-pipe with high-strength rigidity, strengthen the bearing capacity and the air-tightness of pipeline to a great extent, because smooth surface has reduced the surperficial coefficient of friction resistance, played scale effect simultaneously.
Fiber in the individual layer non-woven geotextile is based on polyster fibre, but admixture Ti metal fiber or compound fibers such as glass fibre or polypropylene fibre, vinylon, and its construction operation elastic expansion rate of individual layer non-woven geotextile is 8-18%.Heat sealing is whole the fusion, and it seals no any solvent channel.The waterproof membrane of flexible pipe outside can be PVC or polyurethane material.
Case history: the composite soft tube that buried pipeline adopts trenchless rehabilitation not to use, through φ 325 * 12 residual oil pipelines, die casting iron gas-pipe line among DN300, DN400, the DN600, use the favorable comment that all obtains the owner on first-class nearly 20 reinstatement workss of DN1200 concrete blowdown pipeline and DN750 water-supply line, the thickness of composite soft tube: 3-10 millimeter, length is endless, and thickness error is 0.2 millimeter, and composite soft tube construction elastic expansion rate is 8-18%.
