Water storage ladder for sponge city

Abstract

The invention discloses a water storage ladder for a sponge city, and relates to the technical field of sponge city buildings. The water storage step comprises a plurality of single-stage steps, wherein a water storage chamber is formed in each of the single-stage steps, a water inlet is formed in the two sides of the top of each of the single-stage steps, the water inlet is connected with the water storage chamber, a communicating groove penetrates through the two adjacent single-stage steps, and the communicating groove is connected with the two water storage chambers; and an elastic plate is fixedly connected to the middle side of the upper surface of each of the single-stage step, an elastic bag is connected between the elastic plate and the upper surface of the single-stage step, anda non-Newtonian fluid is arranged in the elastic bag. According to the water storage ladder, the water inlet is formed in each of the single-stage step so as to absorb rainwater on the surface of eachof the single-stage step, by means of a baffle and an adjusting spring, as the rainfall increases, the rainwater passes the effective diameter of the water inlet increased by the baffle squeezing theadjusting spring, the water seepage effect is improved, and the absorption of water flowing down from a high place through the plurality of single-stage steps prevents water from forming a flow alongthe steps and causes water to accumulate at a low place.

Description

technical field [0001] The invention relates to the technical field of sponge city construction, in particular to a water storage ladder for a sponge city. Background technique [0002] Sponge city refers to a city that can adapt to environmental changes and respond to natural disasters caused by rainwater like a sponge, absorb water, store water, infiltrate water, purify water when it rains, and release and use the stored water when needed. The construction of a sponge city requires the cooperation of various building facilities to form the entire system. [0003] As a building facility connecting two grounds with different heights, stairs are used in front of each building, especially where the height difference is large. However, once it rains, the traditional ladder will be wetted by the rain and even generate water flow down the ladder, which cannot perform a good function of water absorption and storage, causing temporary water accumulation on the lower ground, and th...
