Description

Technical Field

[0001] This utility model belongs to the technical field of drainage mechanisms, specifically relating to a roadbed drainage collection mechanism. Background Technology

[0002] Currently, the common method for soft soil foundation treatment of silt strata is the drainage consolidation method. Specifically, a vertical drainage structure is set up in the silt strata, a drainage sand cushion layer is set up above the silt strata, and then water in the silt strata is forced into the drainage sand cushion layer by surcharge pressurization. The water is then discharged into the drainage ditches on both sides of the roadbed through the water collection wells and water pipes in the sand cushion layer.

[0003] During the surcharge pressurization process, the sand cushion layer experiences uneven, wave-like settlement, causing the drainage pipes to bend, resulting in problems such as water accumulation, disconnection, and blockage. This prevents timely drainage of moisture from the sand cushion layer, affecting the effectiveness of soft soil foundation treatment. Therefore, a roadbed drainage collection mechanism was designed to effectively prevent water accumulation, disconnection, and blockage of the drainage pipes, thereby improving drainage efficiency.
