Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal water supply engineering, in particular to an exhaust node structure used in a shallow soil covering area of a water supply pipeline under a road. Background Art
[0002] When municipal water supply pipelines, especially large-diameter water supply pipelines, are laid under roads, the burial depth is sometimes restricted by other underground pipelines. In some areas with a large degree of underground development, water supply pipelines even need to consider the relationship with underground pipeline corridors, subways, underground spaces and other related projects. When the conventional design burial depth of the water supply pipeline conflicts with the elevation of other underground pipelines or structures, the pipeline is often shallowly buried and encapsulated to pass through the existing pipelines or structures from the perspective of economy and ease of implementation. This shallow buried water supply pipeline usually raises the pipeline locally, and exhaust facilities need to be installed from the perspective of pipeline operation safety. However, the pipeline is shallowly covered with soil, and the exhaust well according to the conventional practice of the atlas cannot be implemented. Therefore, in this case, high-point exhaust of the water supply pipeline is an urgent problem to be solved.
[0003] It is not difficult to see that there are still many problems in the prior art. Utility Model Content
[0004] Therefore, in order to solve the above problems in the prior art, the utility model proposes an exhaust node structure for a shallow soil covering area of a water supply pipeline under a road.
[0005] The utility model solves the above problems through the following technical means:
[0006] An exhaust node structure for a shallow soil covering area of a water supply pipeline under a road, comprising:
[0007] A water supply pipe (7), a 90° elbow (4), a water supply short pipe (5), a gate valve (2), and an exhaust valve (1); the water supply short pipe (5) and the gate valve (2) are connected via the 90° elbow (4); the water supply short pipe (5) and the water supply pipe (7) are connected via the 90° elbow (4); the water supply pipe (7) is parallel to the road surface (3) and is laid below the road surface (3); the 90° elbow (4) and the water supply short pipe (5) are laid below the road surface (3); the gate valve (2) and the exhaust valve (1) are arranged above the road surface (3).
[0008] Furthermore, the exhaust valve (1) is installed on the gate valve (2).
[0009] Furthermore, the water supply short pipe (5) is buried under the road surface (3) and is perpendicular to the water supply pipeline (7).
[0010] Furthermore, the water supply short pipe (5) and the 90° elbow (4) need to be encapsulated with reinforced concrete (6).
[0011] Due to the above structural design, the utility model solves the problem of exhaust in water supply pipes with low soil cover under the road surface. The construction and maintenance are simple and convenient, the cost is low, and the impact on the city's beauty and road traffic can be reduced while ensuring the safe operation of the water supply pipe. It is a water supply node structure worthy of promotion and has broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS
