Description

Technical Field

[0001] The invention relates to a water pipe supporting structure, in particular to a water pipe supporting structure that passes through an existing line. Background Art

[0002] Existing lines are railway lines that have been opened to traffic and are officially in operation. When an existing line crosses a river, a bridge is usually built above the river, and the river passes through the bridge hole. When carrying out water pipe construction in a river and encountering crossing an existing line, the water pipe is usually fixed in the riverbed and crosses the existing line together with the river. When a train passes on the railway line on top of the bridge, it will generate a large vibration. The vibration of the train is transmitted to the bridge body, and then transmitted to the river under the bridge body through the bridge piers. Since the water pipe in the river is fixed in the river, the section of the water pipe located in the bridge hole is most seriously disturbed by the vibration of the train. Frequent vibrations can easily cause the welding points of the water pipe to become detached, causing water pipe leakage accidents. Summary of the invention

[0003] In order to overcome the deficiencies in the background technology, the present invention discloses a water pipe support structure that crosses an existing line. Elastic support structures are respectively arranged on opposite sides of a bridge hole to lift up the water pipe in the bridge hole, so that the water pipe between the two elastic support structures is in a suspended state. Springs are used to reduce the longitudinal displacement of the water pipe in the bridge hole, and chains are used to reduce the lateral displacement of the water pipe in the bridge hole, thereby effectively avoiding vibration damage to the water pipe in the bridge hole when a train runs on the existing line.

[0004] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical scheme: The support structure of a water pipe crossing an existing line comprises a bridge body and bridge piers, wherein the bridge piers are two bridge piers respectively located at two opposite river banks of a river channel, the bridge body is mounted on the top of the two bridge piers, and the space surrounded by the bridge body and the two bridge piers forms a bridge hole. An existing line is arranged on the top of the bridge body, and also comprises an elastic support structure, wherein the elastic support structure comprises an elastic support frame, which is two elastic support frames and is respectively arranged at two opposite river banks of a river channel crossing the bridge hole. The elastic support frame comprises a base and a sliding block. The base is a square structure, and upwardly extending sliding rods are arranged at positions near four corners of the top of the base, four sliding holes are arranged on the sliding block at positions corresponding to the four sliding rods, and an upwardly extending support column is arranged at the middle position of the top of the sliding block, the sliding block is slidably sleeved on the four sliding rods by using the four sliding holes, and springs are respectively sleeved on the four sliding rods located between the sliding block and the base, the bottoms of the two bases are respectively fixedly connected to the two opposite river banks, a chain is arranged between the upper ends of the two support columns, and there are two elastic support structures and they are located at opposite sides of the bridge hole.

[0005] The water pipe support structure that passes through the existing line, the support column, the spring, the sliding block, the sliding rod, the fixed pile and the chain are all metal structures.

[0006] The water pipe support structure passing through the existing line is coated with anti-rust paint on the support column, spring, sliding block, sliding rod, fixed pile and chain.
