Mountainous region retaining wall based on sponge city and construction method of mountainous region retaining wall

Abstract

The invention discloses a mountainous region retaining wall based on a sponge city and a construction method of the mountainous region retaining wall. The retaining wall is of a multi-layer structureand comprises a cushion layer arranged at the bottom, a retaining layer arranged at the middle portion and a road layer arranged at the top; the road layer comprises two parts including a road sectionand an overhanging plate, the road section is arranged above soil of a mountain and comprises an asphalt surface layer, pervious concrete and a pebble layer from top to bottom, the road section and the overhanging section are connected through the pervious concrete, a colored pond is arranged on the upper surface of the overhanging section, soil is arranged below the colored pond, and the shape of the outer surface of the overhanging section is fixed through concrete; the cushion layer comprises a drainage ditch and a collecting basin, the side, close to the mountain, of the drainage ditch isarranged to be of a pervious concrete structure, and the other side is a concrete structure; the inner side of the retaining layer is the mountain, the outer side of the retaining layer is the concrete structure, a plurality of rows of water pipes are arranged on the outer wall of the concrete structure of the retaining layer, the upper ends of the water pipes are connected with the colored pond,and the lower ends of the water pipes are connected with the collecting basin. By means of the mountainous region retaining wall, water accumulation can be avoided, and the district environment is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a mountain retaining wall based on a sponge city and a construction method thereof. Background technique [0002] Retaining walls are an indispensable structure for development under special geographical conditions such as mountainous areas. In mountainous cities, every inch of land is often expensive. Mountainous area development has become a necessary trend. How to solve it in today's vigorous development of sponge cities? Low-impact development and utilization in this special terrain has become a difficult problem. In the general mountain retaining wall structures, only a few drain holes are set in the retaining wall, so that the buildings at the foot of the low-lying mountain will cause water accumulation, which will be gradually discharged through the municipal pipe network, thus causing the residents at the foot of the mountain to suffer. Inconvenient travel ...
