Permeable pebble ditch and permeable structure

Abstract

The invention relates to a permeable pebble ditch and a permeable structure. The permeable pebble ditch comprises a pebble surface layer and a permeable channel, wherein the permeable channel is composed of a first permeable layer, a second permeable layer and an infiltration layer arranged in sequence from top to bottom. The first permeable layer is arranged at the same height level of an outer road and an outer green belt separately, the pebble surface layer comprises a plurality of first pebble particles which are arranged in the upper end of the first permeable layer in an inlaid mode, a perforated pipe is buried in the second permeable layer in the pavement direction of the pebble ditch, one end of the perforated pipe extends out from the second permeable layer, and a plurality of rainwater pores are formed in the side wall of the portion, located in the second permeable layer, of the perforated pipe. According to the permeable pebble ditch and the permeable structure, a preliminary slowing effect can be made on rainwater through the pebble surface layer, the rainwater runoff is effectively reduced, rainwater infiltration is promoted, impounded surface water is prevented, and the pebble ditch has a good landscape effect at the same time; through arrangement of the permeable channel below the pebble surface layer, the pebble ditch has the strong capacity of water infiltration, most pollutants in the rainwater can be well removed, the drainage effect is good, and maintenance is simple.

Description

technical field [0001] The invention relates to the technical field of sponge city construction, in particular to a permeable pebble ditch and a permeable structure. Background technique [0002] Drainage pipeline system is an important infrastructure to solve urban drainage and waterlogging prevention. Rainwater collection facilities need to be installed on roads in residential areas, parks, and around paved squares, because the catchment area in this area is relatively small, and the sidelines of roads and paved squares are relatively small. Winding and winding, generally small side ditch is used to collect water. According to the structure of the materials used, the side ditch is divided into soil side ditch, plain concrete ditch, prefabricated concrete ditch, and concrete embedded pebble ditch. Sponge city is a new concept to solve the problem of urban waterlogging. This concept emphasizes the use of natural forces to drain water, and realizes on-site consumption of rai...

AI Technical Summary

Problems solved by technology

However, grass-planting ditch, gravel ditch, and pebble ditch also have many problems, such as poor plant landscape effect in grass-planting ditch, easy to degrade and cause bare soil, pollutants intercepted in grass-planting ditch are easy to silt up, manual cleaning is difficult, and it is difficult to exert long-term benefits

The gravel ditch and pebble ditch have loose surfaces, which are easy to be washed away by rainwater, and there are also problems of difficult maintenance
