Problems solved by technology
[0003] During the use of waterproof boards, it is necessary to spread the waterproof boards on the surface to be waterproofed. The waterproof surface area is large, and the waterproof boards need to be laid side by side and then connected by adhesive tape or welding. This method is likely to cause leakage at the joints. Water seepage problem in welding leakage

The invention discloses a tapering type waterproof plate based on an HDPE material. The tapering type waterproof plate comprises a waterproof plate body; one end of the waterproof plate body is provided with a limiting groove channel, and the other end of the waterproof plate body is provided with a tapering convex strip; first blocking strips are arranged on an interaction surface of a first groove channel and a second groove channel; a first convex strip is in sliding fit with the first groove channel; a second convex strip is in sliding fit with the second groove channel; a third convex strip is in interference fit with a third groove channel; and second blocking strips are fixed to an interaction surface of the second convex strip and the first convex strip. According to the tapering type waterproof plate based on the HDPE material, one side of the waterproof plate is provided with the limiting groove channel, and the other side of the waterproof plate is provided with the tapering convex strip, so that the tapering convex strip of the waterproof plate is matched with a limiting groove channel of another waterproof plate; and the limiting groove channel is in interference fit with the tapering convex strip, the limiting groove channel is tightly attached to the tapering convex strip in an interference fit mode, and all the paved waterproof plates are integrally connected through self-sealing combination, so that the waterproof effect is good, and then welding reinforcement is conducted on joints.
Description
Technical field [0001] The invention belongs to the technical field of waterproof board building materials, and in particular relates to a tapered waterproof board based on HDPE material. Background technique [0002] The waterproof board is an impermeable material made of high molecular polymer as the basic raw material, which can prevent liquid leakage and gas volatilization. It is widely used in construction, transportation, subway, tunnel, and engineering construction. The main function of the waterproof board is to prevent the leakage of liquid and the volatilization of gas. The function of the waterproof board in rock engineering is mainly to prevent seepage and isolation, but at the same time it also plays a role of strengthening and protection. It is mainly used in: seepage prevention of earth-rock dams, rockfill dams, stone masonry dams, concrete dams, tailings dams, sewage reservoir dams, channels, reservoirs, etc., seepage prevention linings of subways, basements and ...
