Synthetic water infiltration capability test apparatus for water permeable ground

Abstract

The invention discloses a synthetic water infiltration capability test apparatus for water permeable ground, which mainly comprises a water source, a water tank, a water level regulator and a rainfall device. Water is pumped into the water tank by a pump from the water source, and then delivered to the rainfall device through a soft water delivery tube for the artificial rainfall. The rainfall device includes a support frame, a water chamber, water head display pipe and nozzles uniformly distributed on the lower portion of the water chamber. The water tank is provided with a water level regulator produced by martensitic bottle, and water heads for keeping the level in the water chamber of the rainfall device constant, so that the rainfall is kept at a determined strength. The test device is capable of testing synthetic water infiltration capability of not only water permeable ground in large area, but also modified water permeable ground in small area. Applying the device, inspection to the water infiltration effect of the water permeable ground pavement is greatly strengthened, and data support to the population of the water permeable ground pavement is provided. Therefore, the apparatus has evident environmental, ecological benefit and economic, social benefit.

Description

technical field [0001] The invention relates to a test device specially for testing the comprehensive water permeability of a permeable ground, in particular to a test device for testing the actual water permeability of a fully paved permeable ground. Background technique [0002] Paving permeable ground is an important means to solve the increase of hardened ground brought about by urbanization. The permeable ground mainly has the following functions: (1) It can not only make the rainfall infiltrate into the ground quickly, thereby eliminating the surface water on the road, but also reduce the storm runoff to the greatest extent, increase the amount of infiltration on the spot, so that the groundwater can be replenished in time; (2) due to This kind of paved ground is air-permeable and water-permeable, so it can maintain soil moisture, reduce surface temperature, improve the living environment of urban surface plants and soil microorganisms, adjust urban climate, and allevi...

AI Technical Summary

Problems solved by technology

[0003] The permeable pavement is a whole composed of multi-layer porous media. It must not only meet the requirements of water permeability, but also meet the requirements of bearing loads such as pedestrians and vehicles. Its overall comprehensive water permeability is affected by the water permeability and porosity of each structural layer. etc. Therefore, the test method and test equipment for soil infiltration capacity cannot be used to test its water permeability

Due to the lack of testing methods and equipment for the actual effect of the permeable ground after paving, it is difficult to define whether the whole is permeable or impermeable, and it is impossible to quantitatively evaluate the actual paving effect

Therefore, the permeable effect of the permeable floor is uneven, and the difference is very large. Some pavement surfaces are permeable but the bottom is impermeable, which cannot play the role of the permeable floor, thus hindering the further promotion of the permeable floor to a certain extent.
