Demand for development.The no-dig technique pipeline rehabilitation engineering technology that the 1970s is applied in Britain, the U.S. and Japan and other countries, especially
It is liner inversion system, also referred to as in-situ solidifying method (Cured in Place Pipe, CIPP) has been promoted the use of for many years in China；
But lining material for repairing, resin, grouting material depend on import for a long time.If critical material expensive, material
Can cooperative device, technique independent development, the popularization and development of China's CIPP technology will necessarily be restricted.
In addition, China's fast industrialization and urbanization, bring the business opportunity of a large amount of new laid pipes, Chinese Urbanization in 2013
Rate is 53%, reaches 60% to the year two thousand twenty is estimated, there are also no small gap and development are empty for 80% Urbanization Rate away from developed country
Between.Meanwhile the maintenance of the existing pipeline in China cities and towns, reparation amount are huge, such as: Beijing various pipes in 2014 are about 16.7 ten thousand km,
And repair replacement pipeline every year and reach 800km, need resin material value to be used to reach 600,000,000 yuan or more in reparation.In recent years,
Country releases the great infrastructures such as city integrated piping lane, smart city, sponge city, " ten, water ", the Belt and Road, all draws
The market of pipeline is moved.

Specific embodiment
Below in conjunction with schematic diagram to the pipeline no-dig technique waterproof repair layer structure of the utility model and repaired pipe
Road is described in more detail, and which show the preferred embodiments of the utility model, it should be appreciated that those skilled in the art can
To modify the utility model described herein, and still realize the advantageous effects of the utility model.Therefore, following description should be by
It is interpreted as the widely known of those skilled in the art, and is not intended as limitations of the present invention.
As depicted in figs. 1 and 2, the utility model pipeline no-dig technique waterproof repair layer structure, the repair layer structure include:
Fibrous base layers 1, the first resin layer 2, the second resin layer 3, foaming glue-line 4 and waterproof layer 5；Two layers in the table of the fibrous base layers 1
First resin layer 2 and second resin layer 3 are coated, the fibrous base layers 1 bend to corresponding with recovery pipeline to be repaired
Cylindrical shape, the waterproof layer 5 are arranged in the internal layer of second resin layer 3, the waterproof layer 5 and second resin layer 3 it
Between the foaming glue-line 4 be set connect.The fibrous base layers 1 are glass fabric, aryl fiber cloth or glass and aramid fiber
Mixed weaving cloth.The fibrous base layers 1 with a thickness of 0.5mm~2mm.First resin layer 2 and second resin layer 3
With a thickness of 0.1~0.5mm.The outer layer of the curved fibrous base layers 1 is fixed with 6 banding of iron wire.The waterproof layer 5 is waterproof rubber
Cushion rubber.Have between 3 inside of the second resin layer and the recovery inner wall of the pipe to be repaired on the end face of the waterproof layer 5 equal
The gradient of even transition guarantees repair layer structure and recovery inner wall of the pipe to be repaired fitting and waterproof sealing.
It is the specific manufacturing process for closing pipeline no-dig technique waterproof repair layer structure in this present embodiment below.
A, the stirring of resin: by two kinds of resins that are of different nature, preparing completion in 1:2 ratio, an open-top receptacle is poured into
It in ironwork or plastic products, is stirred with blender, accomplishes stirring sufficiently, color is uniform.
B, scraping for resin is smeared: the resin that stirring is completed uniformly is scraped on glass fabric with scraper and is smeared.Glass fabric
It should cut and complete by different caliber requirements in advance.Resin scrape smear during, glass fabric should by regulation by several times fold, In
After folding every time, it is necessary to scrape and smear resin.
Glass fabric pre-soaked resin, the volume of resin answer enough fiberfill fibers hose nominal thicknesses and by diameter calculations
Whole spaces, it is contemplated that the polymerization of resin and a possibility that penetrate into pipeline gap to be repaired and connecting portion should also increase
The surplus of 5-10%.
C, the winding of glass fabric: the glass fabric for smearing full resin is wrapped on patcher, in glass fabric
Both ends are fixed with thin wire 3.For the winding tightness of glass fabric with natural, loose for standard, iron wire 3 is fixed with glass fibers
Wei Bu does not scatter for degree.
