Description
Technical field
The utility model relates to a kind of no-dig technique pipe lining material recovery technique, particularly relates to the prosthetic appliance that a kind of not excavating earth surface carries out the no-dig technique pipeline rehabilitation inner lining material of underground piping reparation.
Background technology
Along with the development of urban construction, the demand of Trenchless Technology for Pipe Rehabilitation strengthens gradually.Wherein CIPP pipe rehabilitation technology belongs to adaptability and better, the widely used a kind of technique of repairing quality.CIPP recovery technique environmental pollution is little, little to traffic impact, does not disturb residents, low-carbon (LC), is the west technology that latest domestic is introduced.
CIPP pipe rehabilitation technology is the reparation pipe-lining material pipe resin absorbing material being impregnated with hardening resin being made into one and the same length of pipeline section, by hydraulic pressure and air pressure, this material is overturn or be dragged to sewer or sewage pipe inside.By the contention effect of internal fluid pressure, this material is impelled to be pressed on sewer or sewage pipe medial surface.In this case, by being arranged on the HWS road of this inner lining material inside in advance, circulating-heating is adopted to make it to heat up, heat above-mentioned reparation pipe-lining material, make resin generation chemical reaction, after cured, a new structural pipeline will be defined in pipeline, namely complete the liner reparation of sewer or sewage pipe damaged part.
The heating process that CIPP pipe rehabilitation technology adopts mainly contains cycling hot steam cure technique, circulation mixed vapour curing process, recirculated hot air curing process, its common feature is that thermal source is outside flexible pipe, belong to circulating-heating technique, if the whole world is all in the steam cure technique that the U.S. ASTMF2019-03 performed specifies, the steam curing technique of recirculated water that Saertex company of Germany adopts, the curing process of what American I nliner company and Chinese Tianjin Zhen Jin engineering group company adopted is circulation " steam and air " blender, the recirculated hot air curing process etc. that Tianjin Hua Sai Tube Technology PTY. Ltd. is newly developed.Thermal source, namely heat generating device as heating boiler on the ground, under a constant, hot gas enters flexible pipe from one end, discharges from the other end, finally resin solidification is made by heating to flexible pipe, its maximum weakness is boiler, and boiler belongs to pressure vessel, must move at any time in construction, this causes very large hidden danger to construction safety, and some city not allows boiler to set out on a journey; Another weakness is energy or serious heat loss, and the heat time is long, and the thermal efficiency is low.
Resin is when carrying out the chemical reaction of heat hardening, the resin boiling phenomenon that can harden sharply when temperature is too fast, thus have influence on the intensity of the new pipe of liner, or there is the phenomenon in crack, when old pipeline has breakage or seepage, can form underground water water route at crack place, there is new problem in underground piping.Sun Yueping is that have employed the mode of step heating, the first stage is 73-75 DEG C, and the time is 40-45 minute in order to avoid the too fast problem that heats up in 2009100566779.8 at application number; Second stage is 82-84 DEG C, and the time is 55-60 minute; Phase III is the warm water of 25-30 DEG C, circulating cooling, 30-35 minute.Temperature control operation more complicated, brings certain problem to reparation operation.
In addition, be impregnated with the inner lining material of resin, the impact by environment is comparatively large, and the too high meeting of temperature causes that resin is softening even to flow.Therefore, can only night work be selected during hot weather construction, need to add a large amount of ice cubes during operation and the flexible pipe after impregnating resin is cooled, until flexible pipe ploughs under in pipeline.
Summary of the invention
In order to solve the problems of the prior art, the purpose of this utility model is to provide a kind of prosthetic appliance of no-dig technique pipeline rehabilitation inner lining material simple to operate, by arranging prosthetic appliance in pipeline, completing location repair damaged part, efficiently, stablize, not by the impact of ambient temperature; Prosthetic appliance of the present utility model is simple to operate, and it is convenient to control.
To achieve these goals, the technical solution adopted in the utility model: a kind of prosthetic appliance of no-dig technique pipeline rehabilitation inner lining material, it is characterized in that, comprise dog-house, discharging opening, extrusion device, thermofusion device and handheld component, described dog-house is positioned at the side of extrusion device, described discharging opening is positioned at the opposite side of extrusion device, described extrusion device connects thermofusion device, by thermofusion device effect, the material in extrusion device is heated, described handheld component connects thermofusion device and extrusion device respectively, repair process is completed for gripping prosthetic appliance, described handheld component is provided with thermofusion device switch and extrusion device switch, be respectively used to control opening and closedown of thermofusion device and extrusion device.
Wherein, described dog-house is the circular hole of diameter 5mm, and described discharging opening is the rectangle of length 2cm, width 3mm.
Wherein, described extrusion device is screw extruder, and described thermofusion device is air-heater, and described air-heater is connected with one end of screw extruder, and the hot blast realized in air-heater enters the process of screw extruder.
Compared with prior art, the beneficial effect that the utility model realizes: thermofusion device is positioned in pipeline by the prosthetic appliance of no-dig technique pipeline rehabilitation inner lining material of the present utility model, melt by carrying out heating to macromolecular material, macromolecular material is extruded from discharging opening, solidified repair process.Prosthetic appliance of the present utility model, simple to operate, it is convenient to control, and hot melt curing efficiency is high, efficiently avoid the potential safety hazard that traditional circulating-heating technique causes macromolecular material to produce boiling phenomenon and bring simultaneously.Prosthetic appliance of the present utility model is not on the reparation at piping failure position by the impact of ambient temperature, and this expands the scope of application of this prosthetic appliance to a certain extent.
