Detailed Description
The invention will be described more fully hereinafter with reference to the accompanying drawings and preferred embodiments in order to facilitate an understanding of the invention, but the scope of the invention is not limited to the following specific embodiments.
Example 1:
as shown in fig. 1 to 3, the utility tunnel with the waterproof joint of the embodiment is formed by sequentially jointing a plurality of pipe sections 1 end to end, two adjacent pipe sections 1 are butted to form a joint 11, a first elastic rubber ring 12 and a second elastic rubber ring 13 are sequentially arranged on the joint 11 from the outer ring surface to the inner ring surface of the pipe section 1, and when groundwater or other water permeates into the joint 11, the first elastic rubber ring 12 and the second elastic rubber ring 13 can play a double waterproof role to prevent the water from further permeating into the pipe section 1; a water-swelling material layer 14 is further arranged between the first elastic rubber ring 12 and the second elastic rubber ring 13 in the joint 11, so that even if water flow breaks through the first elastic rubber ring 12, the water-swelling material layer 14 swells immediately after contacting water and seals the joint 11 so as to restore the sealing performance and the waterproof effect; in general, the utility tunnel with the waterproof joint of this embodiment can be from the maintenance after the infiltration appears, can reach good waterproof stagnant water effect.
In this embodiment, a diamond-shaped rubber ring groove 111 is disposed in the seam 11 at the installation position of the first elastic rubber ring 12, and the first elastic rubber ring 12 is diamond-shaped and is embedded in the diamond-shaped rubber ring groove 111; the joint 11 is provided with a triangular rubber ring groove 112 at the installation position of the second elastic rubber ring 13, the vertex angle of the triangular rubber ring groove 112 points to the inner ring surface of the pipe section 1, and the second elastic rubber ring 13 is triangular and is embedded in the triangular rubber ring groove 112. The water-swellable material layer 14 will squeeze the first and second elastomeric rings 12 and 13 after swelling with water.
When water permeates into the joint 11, as shown in fig. 4, the diamond-shaped first elastic rubber ring 12 is subjected to water pressure towards the inside of the pipe gallery, so that the pipe gallery is tightly propped inwards, is tightly attached to the diamond-shaped rubber ring groove 111, and enhances the waterproof effect. As shown in fig. 5, if the first elastic rubber ring 12 starts to permeate water, the water-swellable material layer 14 swells to push the first elastic rubber ring 12 outwards when meeting water, so that the diamond-shaped first elastic rubber ring 12 is tightly attached to the diamond-shaped rubber ring groove 111, sealing is formed again, the waterproof effect of the first elastic rubber ring 12 is restored, and water flow is prevented from further permeation from the outside; meanwhile, the second elastic rubber ring 13 is propped inwards by the water-swelling material layer 14, and the second elastic rubber ring 13 is tightly attached to the triangular rubber ring groove 112 under the propping force and the water pressure of the water-swelling material layer 14, so that the sealing performance is improved, and the waterproof performance is enhanced.
