1. Construction Technology of Waterproofing Membrane by Means of Mechanical Fixing Technology The waterproofing membrane used in the construction of waterproofing membranes mainly includes thermosetting coils, thermoplastic coils and modified bitumen coils. However, the commonly used waterproofing membranes are mainly thermosetting coils and thermoplastic coils. Among them, thermoplastic coils mainly consist of polyvinyl chloride (PVC) and polyolefins (TPO); the most important and most viable of thermoset coils are EPDM waterproof coils, which have a long service life. Strong weather resistance and chemical resistance.
2. Underground engineering pre-paving anti-sticking waterproof technology
The anti-stick waterproof technology for pre-paving underground works is made of polymer self-adhesive film waterproofing membrane. The coil is a multi-layer composite coil made by coating a layer of a non-asphalt polymer self-adhesive layer and a weather-resistant layer on a certain thickness of a high-density polyethylene coil substrate. When using the pre-paste anti-sticking method, the concrete is placed directly on the adhesive layer on the surface of the coil. After the concrete is cured, a complete and continuous bond is formed with the adhesive layer. This bond is formed by the interlocking of liquid concrete and synthetic rubber. High-density polyethylene mainly provides high-strength, self-adhesive layer provides good adhesion performance, can withstand the impact of cracks in the structure; weather-resistant layer can not only make the coil exposed during construction, while providing a non-stick surface for construction workers to walk , enabling the follow-up project to proceed smoothly.
3. Pre-measuring slurry system construction technology
The pre-recommendation slurry system is a waterproof construction technology for joints of underground concrete structures. In the construction of concrete structures, grouting pipes that have a single permeability and are not easily deformed are embedded in the joints. When the joints leak, they are set to the outer surface of the building (structure) to the grouting pipe system. The injection of grout into the tube port seals any gaps and holes in the seam area and terminates leakage. If the building (structure) will leak in the future, the repeatable grouting pipe system can also provide a complete maintenance program. When using ordinary cement, ultrafine cement or acrylate chemical slurry, the system can be used for repeated grouting. Utilizing this advanced pre-metering system can achieve zero leakage.
4. Water expansion rubber seal construction technology
Water-swelling sealant is a one-component, solvent-free, water-swellable, polyurethane-based, amorphous paste that seals leaks around structural joints and reinforcements, tubes, and wires. With double sealing and water stopping function, when the water enters the joint, it can use the elasticity of the rubber (stop the water with compressive stress) and increase the water swelling volume (with expansion pressure and stop water) to fill the gap, and it can stop the water.
5. Anti-seepage construction technology of acrylate grout
Acrylic grouting material is a chemical grouting material used for impervious, plugging and soft ground reinforcement. It has low viscosity and no particle content and can be poured into fine fissures; gel time can be controlled; the gel is impermeable to water, can withstand high water head, has good durability, simple construction process, and good grouting effect. The second-generation acrylate chemical grout is a new cross-linker that replaces the cross-linker N,N-methylenebisacrylamide in the first-generation acrylate chemical grout. The slurry does not contain amide groups. The compounds are more environmentally friendly; at the same time, components that promote the expansion of the gel of the acrylate chemical grout in water have been added, further improving the anti-seepage effect.
6. Composite waterproof construction technology of polyethylene polypropylene waterproof membrane and non-cured waterproof adhesive
At present, new waterproof membranes are mainly divided into polymer modified asphalt and polymer waterproof membranes. Due to the high cost performance of polyethylene polypropylene waterproofing membranes, its application volume ranks first in polymer waterproofing membranes. The polyethylene polypropylene waterproof membrane has a rough surface and can be directly bonded with the cement during the curing process, but since the polyethylene polypropylene waterproof membrane is a flexible material, and the cement or polymer cement is a rigid material, this composite method is a kind of Flexible and rigid connections are less adaptable to deformation at the base. In order to optimize the waterproof function of polyethylene polypropylene waterproof membrane, on the basis of the original composite waterproof construction technology, a waterproof construction technology combining polyethylene polypropylene waterproof membrane and non-cured waterproof binder was derived.
7. Polyurethane waterproof coating construction technology
Polyurethane is a rapidly developing multifunctional polymer synthesis material. Polyurethane waterproof coating is cured by chemical reaction and formed into two types, one-component and two-component. The one-component polyurethane waterproof coating is a polyurethane prepolymer. After being coated on site, it undergoes a chemical reaction with moisture in the air or air to cure and form a highly elastic waterproof coating film. The two-component polyurethane waterproof coating consists of two components, A and B. The component A is a polyurethane prepolymer, and the component B is a curing component. The two components A and B are mixed at a certain mixing ratio on the spot. After coating, it is cured by reaction to form a highly elastic waterproof coating film.
