Waterproof board products are various types of construction need to use the main waterproofing products, storage and use waterproof board is particularly important, for it to remain in force, good quality play a role in the project. Waterproof board is the main structural material of waterproofing and drainage tunnel structure, if the operation is not standardized, it will cause quality problems to the tunnel, the tunnel would seriously undermine durability. We all know that usually require a waterproof plate heat welding torch on the support surface prior nail in the early laps of heat welding, heat welding ring is designed by the manufacturer for by EVA welded steel rings and gaskets composition But in the past, on-site construction, water and hot plate welding weld ring is not easy, not to wear waterproof plate welding, would not achieve the role of water is not soldered securely, easily reach the fixed purpose of shedding water board. After on-site analysis of the reasons contributing to this problem is mainly due to the melting point of water board and the heat caused by welding lap inconsistent, so the need to change the heat welding ring material, so that the melting point of agreement between the two can solve the problem. Therefore, we use the field side of the foot board waterproof material, it is made with a waterproof plate heat welding lap welding, because they are the same material, the melting point is the same, can be solved without a strong waterproof plate welding problems. However, there is a problem to be solved, heat welding ring is designed for manufacturers to have a certain stiffness, and waterproof plate welding ring itself is soft, it must be necessary for processing, in order to completely replace the thermal welding ring, play the role of fixed water board. Therefore, we will post weld ring plate made of two pieces of waterproof bonding, it can achieve stiffness stiffness of the heat welded laps. Pad construction steel shims with nails to nail the early support surface with waterproof board after soldering, no melting phenomenon wear waterproof board, and welding time shortened by nearly half compared with before, welded fully meet the design and specifications. Tunnel construction joints in concrete design requirements for embedded buried water stop. Waterproof construction joints as the main material, half buried water stop request aside, half embedded, and shall be set in the middle of the concrete cross section. Buried water stop at the construction site, because it is a long strip, little attention will not meet the design requirements, prone winding phenomenon. When and were embedded, are generally the earlier part of the construction of concrete in place, and then embedded installation, which requires people to do simultaneously applied, can barely in place, a lot of work and effort. To make installation of buried water stop convenient, efficient, on-site through exploration, summed up a more practical method of construction. When that construction, reinforced with two Φ14 the buried water stop grip, adjust the length of the field, a position reinforced grip should set aside half of the edge; Φ14 reinforced with steel U-making card to card live Φ14 steel, U-shaped steel card spaced not more than 2m. Thus, because the steel is straight, buried water stop will naturally become straight, and this time, and then embedded installation, you only need two individuals to each other with the construction, and the construction effect is significant, it is convenient can meet the design and specification requirements. Wait until after the initial setting of concrete, you can remove the U-shaped card, removed Φ14 steel, continue to prepare for the next use. Do not waste material, but a great saving of time and labor.
