Description

Technical Field

[0001] The present application relates to the technical field of municipal water supply and drainage structure support, and in particular to a pipe hanging support structure and a support system for rough stone retaining wall ditches. Background Art

[0002] The pipeline for collecting sewage often needs to pass through the ditch section, especially when collecting sewage in rural areas. In rural areas, the wall of the sewage collection ditch is mainly made of rubble stone retaining wall. When it is necessary to collect sewage, when passing through the ditch section, hanging pipes are often used to lay pipes in the designated area. Hanging pipes require a stable support system to ensure the safety and stability of the pipeline section.

[0003] The existing pipe hanging support structure is formed by welding three L-shaped steels to form a stable tripod, which is then fixed to the concrete channel wall by expansion bolts to provide support reaction force for the pipes laid through the ditch section. However, when the channel wall is composed of rough stone retaining walls, the following problems arise when the tripod is fixed by expansion bolts:

[0004] (1) The channel wall formed by the rubble retaining wall is formed by stacking and stacking because there is no strong bonding force between the rubble blocks. The connection surface between the triangular support and the rubble blocks in the existing structure is only L-shaped steel, with a small contact interface and poor stability.

[0005] (2) The welded tripod is fixed to the channel wall of the rough stone retaining wall by expansion bolts. The tripod is exposed to the outdoors for a long time and is subjected to physical and chemical weathering, which makes it very easy to be corroded and damaged, causing the pipeline to lose support and affect its normal operation.

[0006] (3) During operation, the pipeline passing through the ditch section is subjected to the combined effects of multiple loads, including wind load, water buoyancy of the water-filled ditch section, and scouring force of water flow in the pipeline. When the expansion bolts cannot pass through the rubble retaining wall and form a stable support system with the soil behind, the existing support structure alone cannot provide sufficient resistance to ensure the long-term safe operation of the pipeline.

[0007] There is no prior art that uses a rough stone retaining wall as a foundation for laying pipelines.

[0008] The information disclosed in the background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to ordinary technicians in the field.
