Jude waterproof board for you to explain a waterproof construction reasons: the aforementioned statistics show that water is a major part of the construction phase water leaking underground works, after some water leaks case analysis found that both the construction and workmanship are not careful reasons, there are reasons for construction management and inspection areas, while using complete underground water board workers 程聚德 different methods of construction specifications, its water leakage causes are not the same. 1 composite lined tunnel commonly used polymer waterproofing plate (coil), the main reasons for its failure are: a, waterproofing membrane material itself is not the beginning and shotcrete lining dense paste, install shock when, back projection and so easy to waterproof board punctured, causing leakage; joint chamber weaknesses b, between the board and the board, the slightest mistake can lead to failure of the entire water system; c, in case there is a large concrete wall voids and uneven parts, secondary lining extrusion and deformation of surrounding rock will stretch waterproof board, especially the binding site prone to fracture failure. Jude waterproof waterproof construction board for you to explain the reasons: 1 spray water tunnel and underground engineering waterproofing system leakage causes: spray waterproof membrane is difficult to ensure its uniformity, although generally spray material ductility is better, but the tensile lower strength Jude waterproof board professional production brands, such as occurs large external force, deformation and displacement of the structure will occur; easily lead waterproof membrane rupture, resulting in failure of the entire water system; addition to the construction method of spraying the construction process requires high precision, but generally works hard to achieve. The reason waterproof concrete waterproofing system failed 2 are: narrow underground engineering Face waterproof board, concrete vibrators-density design is difficult to achieve the degree of impermeability requirements, in addition to the construction of this weak link is also stitched Deformation waterproof measures. For the above reasons explain Jude waterproof board special inventory, waterproof construction process is an important part of the quality assurance project should therefore strengthen the importance of waterproof construction, the development of appropriate construction methods Bye for different waterproof, waterproof construction and build quality testing mechanism.
