Description
Technical field
The present invention relates to a kind of no-dig technique pipe lining material recovery technique, more particularly to a kind of not excavating earth surface carries out the prosthetic appliance and its restorative procedure of the no-dig technique pipeline rehabilitation inner lining material of underground piping reparation.
Background technology
With the continuous development of urban construction, the demand of Trenchless Technology for Pipe Rehabilitation is gradually increased.Wherein CIPP pipe rehabilitation technologies belong to adaptability and repairing quality is preferable, a kind of widely used technique.CIPP recovery technique environmental pollutions are little, little to traffic impact, do not disturb residents, low-carbon (LC), are the west technologies that latest domestic is introduced.
CIPP pipe rehabilitation technologies are the reparation pipe-lining materials for the pipe resin absorbing material for being impregnated with hardening resin being fabricated to one and the same length of pipeline section, the material are overturn or are dragged to inside sewer or soil pipe by hydraulic pressure and air pressure.By the contention effect of internal fluid pressure, the material is promoted to be pressed on sewer or soil pipe medial surface.In this case, by the HWS road being arranged on inside the inner lining material in advance, it is allowed to heat up using circulating-heating, heat above-mentioned reparation pipe-lining material, make resin that chemical reaction to occur, after cured, a new structural pipeline will be defined in pipeline, that is, completes the liner reparation of sewer or soil pipe damaged part.
The heating technique that CIPP pipe rehabilitation technologies are adopted mainly has cycling hot steam cure technique, circulation mixed vapour curing process, recirculated hot air curing process, its common feature is thermal source outside flexible pipe, belong to circulating-heating technique, such as the steam cure technique that the whole world all specifies in the U.S. ASTM F2019-03 for performing, the steam curing technique of recirculated water that German Saertex companies adopt, Inliner companies of the U.S. and Chinese Tianjin Zhen Jin engineerings group company use the curing process of circulation " vapor and air " blender, Tianjin Hua Sai Tube Technology PTY. Ltd. recirculated hot air curing process newly developed etc..Thermal source, i.e. heat generating device such as heating boiler is on the ground, under a constant, hot gas enters flexible pipe from one end, discharges from the other end, by finally making resin solidification to flexible pipe heating, its maximum weakness is boiler, and boiler belongs to pressure vessel, must move at any time in construction, this causes very big hidden danger, some cities not to allow road on boiler to construction safety；Another weakness is energy or serious heat loss, and heat time heating time is long, and the thermal efficiency is low.
Resin is when the chemical reaction of heat hardening is carried out, when the too fast resin boiling phenomenon that can be hardened drastically of temperature intensification, so as to 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, subsoil water water route can be formed at crack, underground piping occurs new problem.
Sun Yueping in order to avoid the too fast problem that heats up, employs the mode of step heating in Application No. 2009100566779.8, and the first stage is 73-75 DEG C, and the time is 40-45 minutes；Second stage is 82-84 DEG C, and the time is 55-60 minutes；Phase III is 25-30 DEG C of warm water, circulating cooling, 30-35 minutes.Temperature control operation is more complicated, brings certain problem to operation is repaired.
In addition, being impregnated with the inner lining material of resin, protected from environmental larger, temperature is too high to cause resin to soften even generation flowing.Therefore, night work can only be selected during hot weather construction, needs during operation plus substantial amounts of ice cube is cooled down to the flexible pipe after impregnating resin, until flexible pipe is ploughed under in pipeline.
