Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] see Figure 1-4 , the present invention provides a kind of technical scheme: comprise base soil layer 1, excavate base soil layer, set slope and ditch bottom downwards on the surface of base soil layer, remove the soil of redundant base soil layer, slope and ditch bottom all carry out Compact to form an inverted trapezoidal base soil layer. The bottom of the ditch of the base soil layer 1 and the slope surfaces on both sides are all paved with a gravel ...

Abstract

The invention discloses an ecological drainage ditch system of a sponge city and a construction method. The system comprises a base soil layer, a gravel layer, a planting soil layer, a fixed plate, abarb, a rectangular through hole, a water seepage layer, a water pipe, a water seepage box body a water permeable hole and permeable geotextile. The municipal ecological drainage ditch system can effectively alleviate the impact of heavy rain on the ecological drainage ditch system, and the high permeability of the ecological drainage ditch system can meet the permeation demand of high precipitation. Not only the greening rate is high, but also certain functions of water purification, water storage, water seepage and water drainage can be achieved. An ecological drainage ditch meets the demandfor building ecological civilization, improves the urban environment, and better maintains the ecological balance. Further, due to the fact that the structure contains organic soil, the microbial community can be formed quickly. The soil is not hardened, the ecological system can be sustained to meet the demand of the sponge city, and the heat island effect of the city can be eliminated and relieved to some extent.

Description

technical field [0001] The invention relates to the technical field of municipal gardens, in particular to an ecological drainage ditch system and a construction method for a sponge city. Background technique [0002] The construction of sponge cities with natural accumulation, natural infiltration and natural purification is the general trend of current urban construction. The core of sponge cities is to give full play to the absorption and penetration of rainwater by green spaces, roads and other facilities. Sponge cities refer to cities that can adapt to the environment like a sponge. It has good "elasticity" in terms of environmental changes and natural disasters. It absorbs, stores, infiltrates, purifies water when it rains, and releases and utilizes the stored water when it is needed, which brings great benefits to people's production and life. convenience. [0003] Ecological ditch is a ditch economy that integrates ecological conservation, tourism, economic developm...
