AI Technical Summary
Existing sliding bearings lack orientation when used for inclined pipelines in open-air environments, resulting in pipeline displacement that does not meet requirements. They are also prone to damage due to factors such as temperature stress and media impact, increasing maintenance costs.
A support structure was designed, including a support ring, a support ring base plate, diagonal bracing feet, reinforcing ribs, and baffles. It is connected to a pre-embedded steel plate by pre-embedded bolts to restrict the lateral movement of the sliding support, allowing the pipeline to only move slightly along the axial direction. Combined with the directional connection of the support pier and the sliding support, the stability of the pipeline is ensured.
It improves the directionality of pipe sliding, reduces friction, extends the service life of the support ring, and lowers operation and maintenance costs.

[0001] The utility model relates to the installation technical field of pressure pipeline in water conservancy and hydropower engineering, especially to a kind of support structure for outdoor pressure water pipeline inclined section. BACKGROUND
[0002] Pipeline transportation is widely used in various industries, and media such as heat, water, natural gas and oil are transported through pipelines. As a transport carrier, the support ring of the metal pipeline is generally connected to the pipeline base (support pier) in a fixed manner. When the pipeline is subjected to external environmental temperature changes and the temperature changes of the transported medium, the pipeline will displace. If the support ring of the pressure pipeline is directly fixed on the pipeline support pier, the support ring will be damaged when the pipeline is subjected to temperature stress, medium impact force, cavitation effect and other factors, resulting in high maintenance cost and affecting the normal operation of the project. Therefore, a sliding support is usually provided between the support ring and the support pier to allow the pipeline to displace without directionality. However, the existing sliding support is usually placed horizontally, and the upper structure of the support is allowed to slide horizontally left and right and front and back, also without directionality. For the relatively steep inclined pipe section of the pressure pipeline in the open environment, the requirement of only allowing the pipeline to displace along the axis direction is not met. SUMMARY
[0003] To solve the above problems, the utility model provides a kind of support structure for outdoor pressure water pipeline inclined section, and the specific technical scheme can be as follows:

[0007] The support pad stones are arranged in pairs on each buttress, and each support pad stone is arranged below the bottom plate of the support ring.
[0008] The embedded bolts are arranged at four legs of the lower steel plate of the sliding support.
[0009] One embedded steel plate is arranged on each support pad stone and located at one side of the support pad stone close to the outer side of the water conveying pipeline.

[0019] The embodiments of the utility model will be described in detail below with reference to the drawings, and the embodiments are implemented on the premise of the technical scheme of the utility model, detailed implementation modes and specific construction processes are given, but the protection scope of the utility model is not limited to the following embodiments.
[0020] As Figures 1-7 shown, the support structure for the inclined section of the outdoor pressure-bearing water conveying pipeline is suitable for the installation of petroleum pipelines, natural gas pipelines, heat pipelines, conveying pipelines and the like, and is especially suitable for the inclined section M of the water conveying pipeline in the open environment in the water conservancy project, which is usually arranged with abutments at both ends of the water conveying pipeline M and is supported with buttress N at the middle pipe section, so that the pipeline has a space for micro-sliding along the pipe axis direction through the special connection structure between the buttress N, the sliding support 1 and the water conveying pipeline M, thereby the frictional resistance generated by the contact between the water conveying pipeline M and the buttress N due to the temperature stress, water hammer effect, cavitation effect and the like can be reduced, and the service life of the sliding support is prolonged, and the operation and maintenance cost of the water conveying pressure pipeline in the open environment is reduced.
[0021] The mounting surface of the aforementioned support N is inclined at the same angle as the water pipeline M, and the connection structure between the support N, the sliding support 1, and the water pipeline M is as follows: A pair of support pads 2 are installed on each support N. The support pads 2 are concrete structures, and their center lines are perpendicular to the central axis of the water pipeline M. Each support pad 2 is provided with four embedded bolts 3 and one embedded steel plate 4. Several support rings 5 are welded and fixed to the water pipeline M. The number of support rings 5 is equal to the number of support N, and each support ring 5 is coplanar with the center line of the support pad 2 below it. The support rings 5 have the same structure. Each support ring 5 has a plate-type inclined support foot 51 on both sides of its bottom. Each inclined support foot 51 has a support ring bottom plate 52 welded to its bottom, parallel to the mounting surface of the support N. Preferably, the support ring bottom plate 52 is also provided with reinforcing ribs 53 located on both sides of the inclined support foot 51, and the reinforcing ribs 53 are perpendicular to the plane of the inclined support foot 51. The diagonal bracing feet 51 and the base plate 52 of the same support ring 5 are symmetrically arranged along the central axis of the water pipeline M, and each base plate 52 of the support ring corresponds to the position of the support pad 2 below it. Both are connected to a sliding support 1 in the following manner: The four feet of the lower steel plate of the sliding support 1 are connected to four pre-embedded bolts 3, thereby connecting the sliding support 1 to the support pad 2; the upper steel plate of the sliding support 1 is welded to the base plate 52 of the support ring, thereby connecting the sliding support 1 to the water pipeline M. This connection method allows the water pipeline M to form a non-fixed connection with the support pad 2, enabling the water pipeline M to slide. Furthermore, a baffle 6 is installed on the pre-embedded steel plate 4 of the support pad 2. This baffle 6 is located outside the water pipeline M and is composed of a horizontal top plate 61, a vertical plate 62, and a horizontal bottom plate 63 connected in sequence. The structure includes a horizontal top plate 61 flush with the bottom plate 52 of the support ring, and the horizontal bottom plate 63 is welded to the pre-embedded steel plate 4 around its perimeter. The baffle 6 effectively restricts the lateral movement of the sliding support 1, preventing lateral deformation and swaying of the water pipeline M. Therefore, the connection structure between the support N, the sliding support 1, and the water pipeline M meets the requirements for inclined installation of the water pipeline M, allowing the water pipeline M to form a non-fixed connection with the support pad 2, and enabling only slight displacement along the pipeline axis. This avoids damage caused by lateral swaying of the pipeline during operation due to shock waves, thereby extending the service life of the sliding support.
[0022] The construction of this utility model includes the following steps:
[0023] The first step is to weld the support ring 5 onto the water pipeline M, and weld the support ring base plate 52 to the bottom of the support ring 5.
[0024] The second step is to pour concrete on the support pier N to form the support pad stone 2. At the same time, pre-embedded bolts 3 and pre-embedded steel plates 4 are installed on the support pad stone 2.
[0025] Thirdly, the sliding support 1 is installed on the support cushion stone 2, wherein the lower steel plate of the sliding support 1 is connected and fixed with the support cushion stone 2 through the embedded bolt 3, and the upper steel plate of the sliding support 1 is welded and fixed with the support ring bottom plate 52;
[0026] Fourthly, the baffle 6 is installed on the support cushion stone 2, the baffle 6 is located outside the water conveying pipeline M, and the bottom of each baffle 6 is welded and connected with the embedded steel plate 4 and the top is flush with the support ring 5 bottom plate.
