Description

Technical Field

[0001] The utility model relates to the technical field of drainage plates, and more specifically, to a novel self-adhesive convex shell type drainage plate. Background Art

[0002] In railway tunnel engineering, the leakage problem of the lining structure poses a major threat to the safe operation of trains and significantly affects the healthy service state of tunnel facilities throughout their life cycle. Traditional drainage plate designs mostly adopt flat forms, focusing on waterproof functions while neglecting the use of natural physical principles such as the siphon effect to promote effective drainage. Convex shell type drainage plates with drainage functions are increasingly attracting the attention of tunnel and underground engineering practitioners.

[0003] Chinese Patent CN219034767U discloses a self-adhesive convex shell type drainage plate. The drainage plate includes a self-adhesive plate, and a protective lining paper is covered on the surface of the self-adhesive plate, which avoids the loss of adhesiveness of the self-adhesive layer due to exposure before construction and ensures the bonding effect during installation. However, although the self-adhesive plate enables convenient pasting and installation through the adhesive layer, long-term exposure to a humid environment or rain erosion may cause a decline in adhesive performance, thereby leading to the debonding phenomenon between the drainage plate and the geotextile, ultimately affecting the overall waterproof and drainage performance and long-term service efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems raised in the above background art, and then a novel self-adhesive convex shell type drainage plate is proposed.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A novel self-adhesive convex shell type drainage plate includes a drainage plate body, and a plurality of one-way convex shells are distributed on the surface of the drainage plate body. The one-way convex shells are fixedly connected with a bonding tape through hot melt pressure-sensitive adhesive.

[0007] Furthermore, a plurality of side columns are provided on the one-way convex shell, and the plurality of side columns are in a wavy fold on the surface of the single-phase convex shell.

[0008] Furthermore, the shape of the one-way convex shell is frustum-shaped, prismatic or elliptic cylinder-shaped.

[0009] Furthermore, the side of the bonding tape away from the drainage plate body is adhered to a self-adhesive geotextile.

[0010] Furthermore, the thickness of the side wall and the top of the one-way convex shell is the same as the thickness of the drainage plate body.

[0011] Furthermore, the top of the one-way convex shell is fixedly connected with a bonding tape through hot melt pressure-sensitive adhesive.

[0012] Further, the unidirectional convex shells are arranged in a straight line or evenly distributed in a plum blossom pattern on the drainage plate body.

[0013] Further, the drainage plate body is formed with overlapping edges on both sides along the width direction.

[0014] Further, there are no unidirectional convex shells in the overlapping edges, and the overlapping edges are in a flat plate shape.

[0015] Further, the two overlapping edges are connected together by hot melt welding or pressure - sensitive cold bonding.

[0016] Further, a number of bonding tapes are linearly arrayed along the width direction of the drainage plate body.

[0017] Further, the bonding tapes are fixed and adhered to the top and side walls of the unidirectional convex shells through hot melt pressure - sensitive adhesives.

[0018] Further, when the bonding tapes are fixedly connected to the unidirectional convex shells, the bonding tapes are in a wavy shape.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. The present utility model will be further described in conjunction with the accompanying drawings and embodiments:

[0026] First Embodiment

[0027] As Figure 1 - Figure 2 shown, a new type of self-adhesive convex shell type drainage and waterproof board includes a drainage and waterproof board body 1. The material of the drainage and waterproof board body can be PE (polyethylene), and recycled materials should not be used for the raw materials. The appearance color should be the natural color of the raw materials. A number of one-way convex shells 11 are distributed on the surface of the drainage and waterproof board body, and a bonding tape 2 is fixedly connected to the one-way convex shell through hot-melt pressure-sensitive adhesive.

[0028] Furthermore, the shape of the one-way convex shell is frustum-shaped, prismatic or elliptical cylindrical.

[0029] Furthermore, as Figure 4 shown, a number of side columns 113 are provided on the one-way convex shell, and the plurality of side columns are in a wavy fold on the surface of the single-phase convex shell.

[0030] Furthermore, the bonding tape is also known as "self-adhesive tape" and "Velcro", and has small barbs on the surface. The side of the bonding tape away from the drainage and waterproof board body is adhered to the self-adhesive geotextile, which plays a role in connecting the convex shell drainage board and the tunnel geotextile.

[0031] Furthermore, the thickness of the side wall 111 and the top 112 of the one-way convex shell is the same as the thickness of the drainage and waterproof board body, and the thickness of the drainage and waterproof board body is preferably 1.0 mm or 1.2 mm. This thickness design not only meets the requirements of drainage and waterproof, but also optimizes the cost and use performance of the material.

[0032] Furthermore, the top of the one-way convex shell is fixedly connected to the bonding tape through hot-melt pressure-sensitive adhesive.

[0033] In at least one embodiment, the one-way convex shells are arranged in a straight line or evenly distributed in a plum blossom shape on the drainage and waterproof board body. This arrangement ensures that water can be quickly discharged and prevents the occurrence of water accumulation.

[0034] Furthermore, lap joints 12 are formed on both sides of the drainage board body in the width direction. There are no unidirectional convex shells inside the lap joints, and the lap joints are flat. In actual production, if the width of the drainage board body is 3.1 meters, the width of the lap joint can be 12 - 15 cm; if the width of the drainage board body is 4 meters, the width of the lap joint can be 17 - 20 cm. The design of the lap joint enables the drainage board to be easily butted during installation, improving the flexibility and convenience of installation.

[0035] Furthermore, the two lap joints are connected together by hot melt welding or pressure - sensitive cold bonding.

[0036] In at least one embodiment, a number of adhesive tapes are linearly arrayed along the width direction of the drainage board body, and the number of adhesive tapes is set according to the width of the coil material. Preferably, an adhesive tape is provided every 50 cm - 150 cm. This design ensures uniform stress on the drainage board in the width direction and improves the stability of the overall structure.

[0037] Second Embodiment

[0038] As Figure 3 shown, the difference from the first embodiment is that the adhesive tape is fixed to the top and side walls of the unidirectional convex shell by hot melt pressure - sensitive adhesive.

[0039] Furthermore, when the adhesive tape is fixedly connected to the unidirectional convex shell, the adhesive tape is wavy. This cooperation not only increases the contact area between the adhesive tape and the base material, thus enhancing the bonding firmness, but also makes the whole structure more beautiful in appearance and better adapts to the requirements of various application scenarios in terms of function.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above - mentioned embodiments. The above - mentioned embodiments and the descriptions in the specification only illustrate the principles of the present invention.
