Description
Technical field
The utility model relates to a kind of no-dig technique pipeline rehabilitation leaching fat electrothermal solidifying fibre pipe, for the reparation of the old pipe network of Urban Underground instantly.
Background technique
Since this century, along with big and medium-sized cities underdrainage system is aging gradually, incident municipal drainage obstacle is more and more serious, constantly occurs the generation of the Disasters such as impeded drainage, urban waterlogging, surface collapse, sewage overflows, and critical juncture has been arrived in underdrainage regulation.But developing rapidly of each metropolitan surface construction and improvement project, make reparation underground pipe network difficulty increasing, especially all buried underground of heavy caliber drain pipe net, if thoroughly excavation renews pipe network, the pipelines such as its crisscross water supply, heat supply, telecommunications will suffer thorough destruction, add that the established appearance of city such as its ground level road, building, greening all will be faced with paralysis.
After entering 2010, some no-dig technique road surfaces start application gradually to the repairing construction technology of old pipe network and repair materials in some big and medium-sized cities both at home and abroad, and its technology mainly adopts no-dig technique inverted liner ultraviolet photo-curing method, no-dig technique inverted liner hot water to inject solidification method, draw in formula forced air solidification method.
Said method Problems existing is: adopt excavating turnover liner ultraviolet photo-curing method, because of the special process of ultraviolet photo-curing technology, production environment, production procedure, storage transport, field operation etc. all need to complete under the condition of low temperature, lucifuge to make it require, field operation must enter down-hole by inverted liner pipe, needs the large complicated implement of input and personnel depaly to carry out job execution.Also thoroughly the solidification effect of inverted liner must effectively could be ensured by the ponding removed in underground pipe network before job execution.Because ultraviolet light polymerization needs thickness of inner lining, beam intensity and resin solidification data demand rigorous, once there is the thick liner operation of Large Diameter Pipeline, very likely cause the solidification of ultraviolet penetrating power deficiency uneven, occur half-cooked phenomenon.
Adopt hot water to inject solidification method, except there is above photocuring inverted liner defect, its maximum shortcoming needs the water filling of erected on site high-capacity boiler exactly, not only causes a large amount of equipment human inputs, and wastes valuable clear water resource greatly.
Formula forced air solidification method is drawn in employing, although solve the problem entering under ground piping without inverted liner, needs fully to clear up and adiabatic drying pipeline, and the power heating air blast that also will have high input equipment can fulfil assignment.
In a word, because the particular surroundings of municipal construction, rush to repair every section of underground pipe network engineering, proprietor can require that unit in charge of construction must repair at the appointed time, and especially bustling block, needs construct midnight, must complete before daybreak.So no matter be ultraviolet photo-curing method, hot water injects solidification method or draw in formula forced air solidification method, all can not meet the engineering time requirement of modern city.
Summary of the invention
The deficiency existed in view of existing construction technology and the special requirement for market, by my company's repetition test, provide one and can overcome the deficiencies in the prior art, complete the reparation of old pipe network at the appointed time and a kind of no-dig technique pipeline rehabilitation leaching fat electrothermal solidifying fibre pipe that construction quality requires can be ensured, do not need in construction thoroughly to remove the ponding in underground pipe network, can construct in extremely severe under ground piping environment completely.
The technical solution adopted in the utility model is: a kind of no-dig technique pipeline rehabilitation leaching fat electrothermal solidifying fibre pipe, described leaching fat electrothermal solidifying fibre pipe comprises TPU overlay film polyester fibre stringing, polyester fibre stringing, heat reactive resin, geomembrane, it is characterized in that: also comprise electrical heating elements, temperature transducer, described TPU overlay film polyester fibre stringing and polyester fibre stringing are all soaked with heat reactive resin, described TPU overlay film polyester fibre stringing peripheral hardware has polyester fibre stringing, the TPU coating layer of TPU overlay film polyester fibre stringing is towards in pipe, one deck geomembrane is had at polyester fibre stringing peripheral hardware, electrical heating elements and temperature transducer is provided with between TPU overlay film polyester fibre stringing and polyester fibre stringing pipe.
Technical characterstic of the present utility model is:
1, the structure installing electrical heating elements between internal layer TPU overlay film ester fiber stringing and outer polyester fibre stringing additional is adopted, utilize electrical heating elements electrified regulation mode, the heat reactive resin solidification that TPU overlay film ester fiber stringing and polyester fibre stringing are soaked with, complete the reparation of under ground piping, instead of ultraviolet light polymerization and the hot-water flooding curing mode of complexity and inefficiency, save the consumption of a large amount of manpower and a large amount of thermal water resource.
2, strata ester fiber stringing outer wall has the geomembrane of high strength outside; under underground pipe network has open fire situation, normally can draw under ground piping and not destroy leaching fat inner lining material; the material protecting again leaching fat, not by water and soil pollution, saves the manpower financial capacity that cleaning in early stage water accumulation of pipeline consumes.
3, soak fat electrothermal solidifying fibre pipe convenient for production, utilize outer painting formula to soak fat, make leaching fat even, accumulating is convenient, does not need lucifuge stored refrigerated.
4, soak fat electrothermal solidifying fibre pipe and arrive job site, use the equipment of simple possible directly can draw in underground pipe network, eliminate complicated upset and enter underground pipe network process, not only save a large amount of manpower and materials, it also avoid the wasting of resources.
5, cost of production and construction cost cheaper, so under equal conditions job execution, its cost performance is higher.
