[0016] The utility model is described in detail below in combination with the drawings and examples. Example
[0017] A waterproof pipe piece, as shown in Figure 1 And Figure 2 It includes pipe piece body 1, pipe piece body 1 adopts the anti -permeable concrete material to make, and the anti -permeable concrete can effectively prevent water penetration, ensure that pipe piece will not be damaged due to seepage in long -term use, guarantee the waterproof performance of pipe piece, and the anti -permeable concrete has very high durability, can resist the erosion of chemical corrosion and ultraviolet radiation, long -term use is not easy to age, crack and deformation, prolongs the service life of pipe piece body 1.
[0018] Specifically, as shown in Figure 1 And Figure 2As shown, the pipe piece body 1 is provided with four symmetrically arranged sliding grooves 2, and the positioning piece 3 is slidably connected in the four sliding grooves 2. The positioning piece 3 is fixedly connected with the positioning column 4, and the diameter of the positioning piece 3 is greater than the diameter of the groove opening of the sliding groove 2. The positioning column 4 is arrayed with a plurality of limiting protrusions 5, and a space for accommodating the rope is formed between adjacent two limiting protrusions 5. By embedding the rope into the space between the limiting protrusions 5, the stable fixing of the rope can be realized, thereby enhancing the connection strength between the pipe piece and the rope, facilitating the full fixing of the pipe piece body 1 and the vehicle, avoiding the shaking of the pipe piece body 1, protecting the integrity of the pipe piece body 1. Since the diameter of the positioning piece 3 is greater than the diameter of the groove opening of the sliding groove 2, the design can prevent the positioning piece 3 from accidentally falling out of the sliding groove 2. Further, the positioning column 4 and the limiting protrusion 5 are made of stainless steel material, which has good wear resistance and high hardness, so that the operator can bundle the pipe piece more stably and conveniently, and ensure the stability during transportation.
