Description

Technical Field

[0001] The utility model relates to the technical field of drainage ditches, in particular to an assembled slope foot infiltration drainage ditch. Background Art

[0002] In projects such as foundation pit slopes, fill roadbed slopes, and excavation slopes, drainage ditches are often set at the foot of the slope to intercept rainwater on the slope surface in order to prevent the projects in the slope foot area from being eroded by rainwater. However, in seasons with abundant rainfall, the slope soil has a higher water content due to the long rain time. This not only causes the moisture in the slope soil to invade the slope foot project, but also the slope stability drops sharply due to the increase in soil saturation. However, the drainage ditch at the foot of the slope can only remove rainwater on the slope surface and cannot infiltrate rainwater in the slope soil.

[0003] The above information disclosed in the background technology section is only used to enhance the understanding of the background of the present invention and therefore may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content
