Description

Side slope platform drainage structures

Technical Field

The utility model relates to a slope building construction technology, in particular to a slope platform drainage structure.

Background

At present, the requirements on the overall greening effect of the slope body are higher and higher, the three-dimensional net greening, ecological bag greening, spray-mixing vegetation greening and the like are generally adopted for slope greening at present, but the greening is basically not carried out on the position of a slope platform, or the concrete platform is adopted for hardening, so that the position of the platform is free from vegetation coverage, the greening effect after the treatment is affected, the effect that the treated side slope is not harmonious with ecology of surrounding mountain bodies is also easily given to the treated side slope from an aerial photo, and particularly for high and large side slopes, the influence on the overall greening effect is particularly obvious due to the existence of a multi-stage platform. For this reason, a slope catwalk platform greening and protecting combined structure disclosed in the publication No. CN210857234U is provided with an inner side drainage ditch for effectively draining rainwater or surface water flow converged on the slope; the planting groove formed by the low retaining wall and the outer ditch wall of the drainage ditch is connected with the foundation slab of the drainage ditch into a whole, and the backfill soil on the inner side carries out greening planting, so that the coordination and the attractive appearance of the environmental greening are realized.

But the problem that the green plants in the planting grooves are easy to lack water can occur in the using process. Mainly because the current slope platform is mainly 1-2 meters wide, the fewer objects on the platform are required to be better and the lighter objects are required to be better in consideration of the bearing capacity of the slope surface. Therefore, the width of the planting groove cannot be designed to be large, the depth of the planting groove is also not large, and due to the fact that the groove width is not large and the shielding of plants is added, less water can penetrate into soil in rainy days. And because of the restriction of design requirement to planting groove volume, its earthing is also less, can lead to planting inslot water storage ability relatively poor like this. When drought comes, soil in the planting groove is easy to dry. The planting groove is formed by a plate surface cast by cement concrete, and the root of the green plant is limited in the planting groove, so that the phenomenon of water shortage and wilting easily occurs in the green plant.
