Background
With the acceleration of the urbanization process of China, urban underground pipelines are increasingly constructed, the scale of a pipe network is continuously enlarged, the phase sequence of partial pipelines reaches the service life, and phenomena of 'running, overflowing, dripping, leaking' and the like occur in succession. However, repairing old pipelines by using the traditional excavation repairing technology not only affects traffic and surrounding environment, but also has expensive repairing cost. In this case, trenchless pipeline rehabilitation is particularly important.
In recent years, the trenchless repair technology for urban underground pipelines in China is developed rapidly, and the trenchless repair technology can repair various functional and structurally damaged pipelines. In addition, the non-excavation technology adopts special construction equipment, technology and materials, and has the characteristics of high construction efficiency, good engineering quality, short construction period, small influence on traffic and the like. The method is widely applied to repair of damaged pipelines such as water supply, drainage, gas and the like.
But the initiation of the non-excavation repair technology is late in China. The trenchless repairing material is seriously dependent on import, so that the repairing cost is high and the construction period is difficult to guarantee. Therefore, the research of the home-made trenchless in-situ repair material is urgently needed in China. The non-woven fabric is one of the most commonly used materials in the non-excavation technology, and is synthetic fiber with the largest production scale and use amount in China. The synthetic fiber has the advantages of high strength, high elastic modulus, large porosity, good heat resistance and wear resistance, good dimensional stability, low cost and the like; in addition, the TPU film has the advantages of high wear resistance, wide hardness range, high mechanical strength, outstanding cold resistance, good processability, oil resistance, water resistance, mildew resistance and regeneration benefit. The special geotextile membrane is formed by compounding two materials, combines the characteristics of the two different materials, has excellent tensile strength, elasticity, strength and seepage-proofing performance, and meets the requirement index of non-excavation repairing technology on the materials.
SUMMERY OF THE UTILITY MODEL
