Description

Technical Field

[0001] The utility model relates to the field of tunnel waterproofing, in particular to a waterproof board with grooves. Background Art

[0002] At present, the existing tunnel waterproofing device usually includes self-adhesive cloth (or geotextile), installation nails, adhesive plastic blocks and waterproof boards. When laying, the adhesive plastic blocks and the self-adhesive cloth (or geotextile) are first nailed to the initial support of the inner wall of the tunnel by installing nails, and then the waterproof board is laid on the self-adhesive cloth (or geotextile), so that the self-adhesive cloth (or geotextile) and the adhesive plastic blocks are located between the initial support and the waterproof board, and finally the place containing the adhesive plastic blocks in the waterproof board is heated by a hot melt gun, so that the adhesive plastic blocks can melt and then adhere to the self-adhesive cloth (or geotextile) and the waterproof board respectively. However, adopting this method will cause damage to the hot melt connection of the waterproof board itself (the connection of the waterproof board itself will melt at the same time), which can easily cause the hot melt connection of the waterproof board to become thinner, affecting its own strength, and even cause damage affecting the waterproof effect. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a waterproof board with grooves. This utility model adopts the following technical solutions:

[0004] The utility model provides a waterproof board with grooves, comprising a self-adhesive cloth and a waterproof board, wherein the self-adhesive cloth and the waterproof board are connected by a plurality of adhesive tapes; the waterproof board is provided with a drainage groove group on a side facing the self-adhesive cloth.

[0005] Preferably, the drainage trough group includes two transverse troughs, which are spaced apart in the width direction of the waterproof board, and the transverse troughs are 80 to 100 mm away from the edge of the waterproof board;

[0006] A plurality of longitudinal water troughs are arranged at intervals between the two transverse water troughs. The ends of the longitudinal water troughs are connected to the transverse water troughs. The distance between two adjacent longitudinal water troughs is 1.5m to 2.0m.

[0007] Preferably, the depth of the longitudinal water groove is 0.3-0.7 mm, and the depth of the longitudinal water groove increases gradually from the longitudinal center line of the plate toward both sides.

[0008] Preferably, the adhesive tape is arranged between two adjacent longitudinal water grooves, and the adhesive tape is bonded to the non-grooved portion of the waterproof board by coating hot melt adhesive.

[0009] Preferably, the width of the adhesive tape is 7 to 10 cm, and the interval between two adjacent adhesive tapes is 2 to 3 m.

[0010] Preferably, the drainage trough group is sprayed with a polytetrafluoroethylene coating with a coating thickness of 0.1 mm.

[0011] Compared with the prior art, the beneficial technical effects of the present invention are:

[0012] First, the waterproofing panels are physically bonded using adhesive tape and self-adhesive fabric during construction, avoiding the conventional hot-melt gasketing process and preventing damage to the waterproof layer. Second, the design of drainage grooves in the waterproofing panels enhances both waterproofing and drainage. The grooves are coated with a polytetrafluoroethylene layer, which not only strengthens the material but also reduces its friction coefficient, improving drainage. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 and 2 As shown, this embodiment discloses a waterproof board with grooves, including a self-adhesive cloth 1 and a waterproof board 2, which are connected by a plurality of adhesive tapes 3; the waterproof board 2 is provided with a drainage trough group 4 on the side facing the self-adhesive cloth 1.

[0020] The waterproof board 2 is made of ethylene-vinyl acetate copolymer (EVA) resin, polyethylene (PE) resin, metallocene polyethylene (MPE) resin, special additives and anti-aging agents, and its thickness is 1.0-1.5mm.

[0021] In this embodiment, the drainage trough group 4 includes two transverse troughs 401 . The two transverse troughs 401 are spaced apart in the width direction of the waterproof board 2 . The transverse troughs 401 are 80 to 100 mm away from the edge of the waterproof board 2 .

[0022] Several longitudinal water grooves 402 are spaced apart between the two transverse water grooves 401. The ends of the longitudinal water grooves 402 are connected to the transverse water grooves 401, and the distance between two adjacent longitudinal water grooves 402 is 1.5m to 2.0m. The depth of the longitudinal water grooves 402 is 0.3 to 0.7mm, and the depth of the longitudinal water grooves 402 increases from the longitudinal centerline of the board toward both sides.

[0023] In this embodiment, the adhesive tape 3 is arranged between two adjacent longitudinal grooves 402 and is bonded to the ungrooved portion of the waterproof board 2 by applying hot melt adhesive. The width of the adhesive tape 3 is 7 to 10 cm, and the interval between two adjacent adhesive tapes 3 is 2 to 3 meters.
