Description

Technical field:

[0001] The utility model relates to the technical field of roadbed engineering, in particular to a high groundwater level roadbed partition structure. Background technology:

[0002] High groundwater level refers to the situation where the water level in the underground aquifer is higher. There are both natural and man-made reasons for the rise in groundwater level. Natural reasons include a short-term increase in rainfall, changes in the direction of underground rivers in karst areas, abnormal seismic activity, etc. Man-made reasons mainly include artificial water replenishment and irrigation. High groundwater level will cause a series of hazards. First, it may affect buildings, destroy the overall structure, cause the soil to soften, and even cause the collapse of buildings in severe cases. Secondly, high groundwater level will damage the ecological environment, cause geological changes such as ground collapse or ground fissures, and may also cause water quality deterioration, resource depletion and other problems. In addition, high groundwater level may also trigger a series of natural disasters.

[0003] During roadbed construction, it is necessary to rationally plan the underground drainage system to ensure that rainwater can penetrate and drain quickly, and prevent rainwater accumulation from causing the groundwater level to rise. When the groundwater level rises rapidly, the existing roadbed structure cannot drain the water quickly, and the drainage effect is not good enough. Summary of the invention:

[0004] The utility model provides a roadbed partition structure in a high groundwater level situation according to the deficiencies of the prior art, so as to solve the problems raised in the above-mentioned background technology.
