Description

Technical Field

[0001] This utility model relates to the field of tactile paving technology, and in particular to a tactile paving rubber roll. Background Technology

[0002] Tactile paving is a road facility specifically designed to assist blind people in walking. It is generally paved with two types of bricks: one is a strip-shaped guide brick to guide blind people forward with confidence, called a walking tactile paving; the other is a warning brick with dots to indicate that there is an obstacle ahead and it is time to turn, called a warning tactile paving. Currently, tactile paving bricks are mainly precast cement bricks, which have the disadvantages of being heavy and inconvenient to assemble and disassemble.

[0003] Chinese patent CN214089326U discloses a tactile paving rubber roll, comprising an upper roll and a lower roll, with the upper roll adhered to the lower roll; both the upper and lower rolls are soft rubber layers; the upper surface of the upper roll has several raised directional strips evenly distributed along the length of the roll; the bottom surface of the lower roll has several raised ribs spaced parallel to each other along the length of the lower roll; several connecting strips are provided between adjacent ribs, perpendicular to the ribs; the ribs and connecting strips are integrally formed with the lower roll. This utility model of a tactile paving rubber roll features a simple and reasonable design, convenient installation, good ground adhesion, stable and reliable ground coverage, high structural strength, and long service life; enabling visually impaired individuals to walk easily with the aid of a cane.

[0004] In the aforementioned patent, the upper layer of the roll material is flat, and multiple raised guide strips are provided on the upper layer of the roll material. When it rains, the numerous raised guide strips will block the rainwater on the upper layer of the roll material, causing poor flow of rainwater and resulting in the accumulation of a large amount of rainwater on the upper layer of the roll material, which is not conducive to use. Therefore, in view of the above situation, there is an urgent need to develop a simple structure and good drainage performance of tactile paving rubber roll material to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0005] The purpose of this invention is to provide a tactile paving rubber roll to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tactile paving rubber roll includes a rubber substrate layer, raised ribs, drainage holes, connecting rods, and drainage grooves. The upper end of the rubber substrate layer is arc-shaped, and the middle of the rubber substrate layer is higher than the two ends. Multiple raised ribs are fixed on the upper side of the rubber substrate layer, and the top surfaces of the multiple raised ribs are flush. Multiple connecting rods are fixed on the bottom of the rubber substrate layer. Multiple drainage holes are provided on the rubber substrate layer, and multiple drainage grooves are provided on the bottom of the rubber substrate layer.

[0008] Preferably, both the raised ribs and the connecting rods are bonded and fixed to the rubber substrate layer with adhesive.

[0009] Preferably, the rubber substrate layer, the raised ribs, and the connecting rod are all made of styrene-butadiene rubber.

[0010] Preferably, the drainage channel runs in a left-right direction.

[0011] The beneficial effects of this utility model are as follows: When using this tactile paving rubber roll, the connecting rod is buried in the ground, increasing the stability of the connection between the rubber substrate layer and the ground. When it rains, because the middle of the rubber substrate layer is higher than both ends, rainwater on the rubber substrate layer slides to the sides. Simultaneously, rainwater can flow into the ground through the drainage holes, and rainwater at the bottom of the rubber substrate layer can be discharged to the left and right along the drainage channels, thereby improving drainage performance. In summary, this utility model has a simple structure and excellent drainage performance. Attached Figure Description

[0016] 1. Rubber substrate layer; 2. Raised ribs; 3. Drainage holes; 4. Connecting rods; 5. Drainage grooves. Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] See Figures 1-3 In this embodiment of the present invention, a tactile paving rubber roll includes a rubber substrate layer 1, raised ribs 2, drainage holes 3, connecting rods 4, and drainage grooves 5. The upper end of the rubber substrate layer 1 is arc-shaped, and the middle of the rubber substrate layer 1 is higher than the two ends, so that rainwater on the rubber substrate layer 1 can slide off to both sides, thereby reducing water accumulation on the rubber substrate layer 1. A plurality of raised ribs 2 are fixed on the upper side of the rubber substrate layer 1, and the top surfaces of the plurality of raised ribs 2 are flush, so that blind people will not feel any unevenness when stepping on the plurality of raised ribs 2. Multiple connecting rods 4 are fixed to the bottom of the rubber substrate layer 1. The raised ribs 2 and the connecting rods 4 are all bonded to the rubber substrate layer 1 with adhesive. The rubber substrate layer 1, the raised ribs 2 and the connecting rods 4 are all made of styrene-butadiene rubber, which is a synthetic rubber with good wear resistance, heat resistance and aging resistance. Multiple drainage holes 3 are provided on the rubber substrate layer 1, and the drainage holes 3 penetrate the rubber substrate layer 1. Multiple drainage grooves 5 are provided at the bottom of the rubber substrate layer 1, and the drainage grooves 5 run from left to right.

[0020] Working principle: When using this tactile paving rubber roll, the connecting rod 4 is buried in the soil to increase the stability of the connection between the rubber substrate layer 1 and the ground. When it rains, because the middle of the rubber substrate layer 1 is higher than the two ends, the rainwater on the rubber substrate layer 1 can slide to both sides. At the same time, the rainwater can flow into the ground through the drainage hole 3, and the rainwater at the bottom of the rubber substrate layer 1 can be discharged to the left and right sides along the drainage channel 5, thereby improving the drainage performance.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
