Abstract
Description
Technical Field
[0001] The utility model relates to the field of water supply engineering, in particular to a pier structure of an exposed steel pipe across a gully. Background Art
[0002] In water supply projects, due to the long water transmission lines and the ever-changing terrain along the water transmission pipelines, it is difficult to avoid crossing gullies, valleys and other areas. For open water pipes, to safely cross gullies, common practices are: Method 1, adopt a bridge plan, the bridge piers are located on the solid and complete foundations on both sides of the ditch, and the open water pipes pass through the bridge; Method 2, set up a retaining dam upstream of the ditch, and set up a diversion channel to intercept and divert the ditch water to other places, and the steel pipe passes through the bottom of the ditch. In actual projects, the bridge piers of Plan 1 have higher requirements for the foundation, and often need to be excavated to the fresh weakly weathered layer, the excavation is large, and there are certain safety risks; Plan 2 has a large amount of interception and diversion engineering, or there is no diversion condition. At this time, other safe and reliable crossing methods need to be adopted.
[0003] Based on the above situation, the utility model proposes a pier structure with an exposed steel pipe across the gully to effectively solve the above problems. Utility Model Content
[0004] In order to solve the problems existing in the background technology, the utility model provides a pier structure of an exposed steel pipe across a gully.
[0005] The utility model adopts the following technical solutions:
[0006] A pier structure with exposed steel pipes across gullies, comprising a pier and a steel pipe, wherein the pier is arranged at the intersection of the gully and the contour line, the steel pipe is passed through the pier, anchor rods are arranged at the bottom and inner side of the pier, drainage culverts are pre-buried at the excavation surface at the bottom and inner side of the pier, and an energy dissipation surface is arranged at the outer side of the pier.
[0007] Furthermore, the anchor pier is a reinforced concrete anchor pier.
[0008] Furthermore, the bottom of the anchor pier is arranged on a rock foundation.
[0009] Furthermore, the anchor rod is arranged perpendicular to the surface of the pier, and a plurality of anchor rods are provided.
[0010] Furthermore, an open drainage channel is provided on the top of the town pier.
[0011] Furthermore, the energy dissipation surface is a tooth wall.
[0012] Furthermore, the comprehensive slope ratio of the tooth wall is 1:0.35.
[0013] The utility model provides an exposed steel pipe gully-spanning anchor structure, which has the advantages of simple structure and high stability, can safely and reliably span the gully, can effectively reduce the construction difficulty, the engineering workload and investment, and is easy to promote and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0018] See attached Figure 1-2 A pier structure with an exposed steel pipe across a gully, comprising a pier 5 and a steel pipe 4, wherein the pier 5 is arranged at the intersection of the gully 1 and the contour line, and the steel pipe 4 is passed through the pier 5. Anchor rods 2 are arranged at the bottom and inside of the pier 5 to maintain the stability of the pier. A drainage culvert 3 is pre-buried at the bottom and inside of the pier 5, and the pipe diameter is determined according to basic information such as the catchment area and the slope of the gully 1. In order to dissipate the energy of the ditch water flowing through the top surface of the pier 5 and reduce the scouring of the original ground downstream, an energy dissipation surface is arranged on the outside of the pier 5.
[0019] The anchor pier 5 is a reinforced concrete anchor pier. The bottom of the anchor pier 5 is arranged on a stable rock foundation.
[0020] The anchor rod 2 is arranged perpendicular to the surface of the anchor pier 5, and a plurality of anchor rods 2 are provided.
[0021] The top of the anchor pier 5 is provided with an open drainage channel 6 for draining gully water during operation. The width and height of the open drainage channel 6 are determined according to information such as the gully properties, catchment area, gully slope, and design standards.
[0022] The energy dissipation surface is the tooth wall 7, and the comprehensive slope ratio of the tooth wall 7 is 1:0.35.
