High pressure sealing the needle: the use of loop fastening pressure principle. The head of a one-way shut-off valve Anhui waterproof material to prevent slurry under high pressure push down spray. Central pressure bulge rubber tube with a diameter of 13MM, inserted into the aperture of the grouting holes 14MM, and tighten the pressure bolt ring, compressed rubber casing, so grouting grouting mouth fixed in the hole. (Grouting nozzle check valve to the pressure to open at 0. 4KN or more, so grouting pressure must be higher than this value). High pressure sealing the needle are currently four types: copper mouth, mouth aluminum, steel nozzles, plastic nozzle, the first three of the ring compression. Divided into pre-sealing type, namely filling the mouth of the inlet check valve located at the entrance; After sealing type Henan waterproof material, namely the inlet of the check valve located at the exit, depending on the particular situation of choice. After laying a good mouth before sealing type, you can unscrew the front to relieve pressure drainage, to be screwed again filling up; seal type buried after a good mouth, you can not drain relief, but the construction is completed filling the mouth can be dismantled Construction of the next process. Some common rubber seal filling nozzle diameter of 14mm, 14mm drill bit. Dense structure chosen for the length of 7 ~ 8cm filling nozzle; pair of loose structure, the choice of length 10 ~ 15cm grouting mouth. Waterproof mortar: the positive application of polymer cement waterproof mortar, advocate polypropylene fibers (PP) and nylon fiber and wood fiber cracking waterproof mortar, siliceous zeolite research applications dense water repellent. Vigorously promote the use of mortar (water, heat, corrosion, bonding, sealing and other special self-leveling mortar). 6 synthetic polymer waterproofing membrane: the consolidation of PVC and EPDM waterproofing membrane applications, advocates forming a polyethylene fiber (polyester polypropylene) waterproof membrane and polymer cement bonding system to accelerate research and development of wet-laid process Self-adhesive synthetic polymer waterproofing membrane, restricting the use of chlorinated polyethylene waterproofing membrane, out of recycled rubber waterproofing membrane. 7 polymer modified bitumen membrane: the consolidation of applications SBS, APP modified bitumen membrane and, to develop a wet-laid process of self-adhesive modified bitumen membrane waterproofing materials to promote the practice and application of green roofs root volume resistance Materials Beijing waterproof material, the positive application of fiberglass asphalt shingles tires, restrictions on the use of composite tire tread bitumen membrane and paper linoleum, prohibit the use of coal tar sand surface waterproofing membrane. 8 Special: Select Application metal waterproofing membrane, heritage studies and other special waterproof coating application.
