Description
Technical field
The utility model belongs to technical field of composite materials, particularly relates to a kind of composite repaired for pipeline inversion method.
Background technology
Urban drainage pipe network is the important component part of city basic engineering; the management of urban drainage pipe network is significant to the protection of urban environment, urban construction and economic development; it is the important symbol weighing urban modernization management; municipal drainage pipe duct is the important leverage facility of Urban Water Pollution Control and drainage waterlogging prevention, but exist at present municipal drainage pipe duct detect not yet universal, maintenance of equipment falls behind, pipe duct reparation only has a small amount of exploration and the main problem relying on foreign technology.The exploitation of the maintenance of municipal drainage pipe duct, diagnosis, maintenance technique and equipment is the important support of municipal drainage safety guarantee, controls and waterlogging prevention for urban pollution resource, strengthens the diagnosis of sewer, maintenance, maintenance work more and more highlight important.
At present, more at the subsoil drain total length about 5.8 ten thousand kilometers that China is on active service more than 20 years, there is the phenomenon such as seepage, corrosion in these old pipelines, will be easy to cause the accidents such as road landslide, pipeline burst once be subject to external disturbance.But China does not also form maintenance, the rehabilitation plan of the existing pipeline of a system at present, is substantially also in a kind of the state for the repair process of accident pipeline section.Compared with developed countries, there is larger gap in water supply and drainage pipeline rehabilitation and the technology of replacing application aspect in China.The non-excavation repairing technique of current China independent development cans be counted on one's fingers, and the case adopting non-excavation repairing technique to carry out water supply and drainage pipeline rehabilitation is also few, and within 2009, China's drainage pipeline adopts the length of non-excavation repairing technique only to have 27.92km.For Beijing, 2006 ~ 2007 years, transform last century 50, the pumping equipment that is about 30km the sixties, part have employed the trenchless technologies such as expander, Directional Drilling, liner and constructs, length reaches 8km, and non-excavating construction amount accounts for 27% of total length.And external as the U.S. since two thousand five, trenchless technology is changed at drainage pipeline and is reached more than 65% with the application in reparation.
Along with the progress of Chinese Urbanization, urban architecture density and urban road load increase day by day, especially some old towns, underground piping is staggered complicated, a lot of pipeline position is failed to understand, carries out drainage pipeline reparation, easily cause various engineering technology problem according to the method for pipe laying again after excavation.Trenchless sewer repair technique has and reduces traffic impact, trouble of avoiding removing, reduces ambient influnence, avoids the series of advantages such as roadbed subsidence or seeping phenomenon generation and be subject to the attention of Industry regulatory bodies.
Fast based on speed of application, the in-situ solidifying technology that the aspect that affects is little, the situation of repair materials dependence on import is broken not yet, thus brings the high shortcoming of rehabilitation cost.When the function guarantee of the hidden infrastructure of Urban Underground is further important, be necessary to research and develop the repair materials being suitable for China's national situation, Guan Qing.
Utility model content
Problem to be solved in the utility model is for above-mentioned deficiency, provides a kind of composite repaired for pipeline inversion method.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of composite repaired for pipeline inversion method, described composite comprises tubing basic unit, resin bed and watertight composition, the inner surface of described tubing basic unit is connected with described watertight composition is gluing, and the outer surface of described tubing basic unit has described resin bed.
In a kind of concrete embodiment, described tubing base material is non-woven fabrics.
As the scheme that the utility model is more preferably, described non-woven fabrics adopts polyester material, fabric width 1-8m, percentage elongation 30%-100%, weight per unit area 400g/m
2-1200g/m
2, mass deviation ± 5%-± 8%.
In a kind of concrete embodiment, described resin bed adopts polyurethane material.
In a kind of concrete embodiment, described watertight composition adopts PU film, and thickness is 0.5mm, heat distortion temperature >=200 DEG C.
As the most preferred scheme of the utility model, this composite comprises nonwoven layer, resin bed and PU rete, wherein, non-woven fabrics is connected with PU film is gluing, resin-coating is on non-woven fabrics, in use, resin-dipping is inner to non-woven fabrics, by resin solidification effect, make the flexible pipe made via non-woven fabrics be fixed on inner-walls of duct, thus form liner pipe.
The advantage that the utility model has and good effect are: after upset construction, watertight composition can tolerate the etch of flowing water body in pipeline, and inner hose and resin are formed and firmly upgrade pipeline; Restoration updating pipe lining tube-surface is bright and clean, smooth, effectively ensures the recovery of restoration updating function pipeline.

In figure: 1-PU film; 2-nonwoven layer; 3-resin bed; The old pipeline of 4-.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
The composite of the present embodiment comprises three layers, please refer to Fig. 1, and basic unit's material is polyesters non-woven fabrics, and specifically, its fabric width is 4m, and percentage elongation is 55%, and weight per unit area is 1200g/m
2, thickness is 15mm, and mass deviation is ± 6%; Resin bed adopts performed polymer type polyurethane resin; Watertight composition adopts PU film 1, and thickness is 5mm, and heat distortion temperature is 210 DEG C.Wherein, nonwoven layer 2 adopts adhesive means to be connected with PU film 1, and resin bed 3 is coated on non-woven fabrics.
This kind of material is adopted to repair broken pipe, Fig. 2 is please refer to after Old pipeline's rehabilitation, after tested (hot strength is carried out according to " the mensuration GB/T10654-2001 of high polymer stephanoporate elastomeric material hot strength and elongation rate of tensile failure ", bending strength carry out according to " textile fibreglass reinforced plastics roving strengthens the mensuration part 2 of resin rodlet mechanical performance: the mensuration GB/T14208.2-2009 of bending strength "), the renewal pipeline that its inner hose and resin are formed, its hot strength is greater than 12MPa, bending strength is greater than 31MPa, bending modulus 1724MPa.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
