Embodiment 1
[0038] Embodiment 1: a kind of urban and rural surface ditches transformation method with interception function, comprises the following steps:
[0039] S1. Ditch trimming;
[0040] S1-1. Remove debris and vegetation in the original ditch, trim the original ditch to a width of 50cm, a depth of 70cm, and a slope ratio of 1:1. After trimming, the cross section of the ditch is a trapezoidal structure;
[0041] S1-2. Perform compaction treatment on the repaired ditch, and perform concrete reinforcement treatment on the loose soil inside the ditch;
[0042] S2. Ditch reinforcement;
[0043] S2-1. Laying a composite fiber net on the inner surface of the ditch treated in step S1-2, with both sides of the composite fiber net 20 cm higher than the top of the ditch, and anchoring the composite fiber net and the top of the ditch;
[0044] S2-2. Support the mold in the ditch, adapt the mold to the ditch structure, and adjust the distance between the mold and the inner wall of the ditch ...
