Abstract

The invention discloses a measuring cylinder device used for testing the permeable rate of the permeable concrete pavement. The measuring cylinder device comprises a horizontal support plate and a vertical measuring cylinder, wherein a groove is arranged in the center of the upper plane of the support plate, the bottom of the measuring cylinder is inserted and connected into the groove, a water outlet pipe is vertically arranged under the support plate, the upper end of the water outlet pipe is communicated with the bottom of the measuring cylinder, and a valve is arranged on the water outlet pipe. Through the recording of the water column descending height in the measuring cylinder and the required time, the permeable rate of the paved permeable concrete pavement can be precisely calculated.

Description

technical field [0001] The invention belongs to the technical field of testing devices, and in particular relates to a water permeability testing device for testing the water permeability of permeable concrete pavement. Background technique [0002] Permeable concrete, also known as porous concrete and permeable floor, is a kind of porous lightweight concrete made by mixing aggregate, cement and water. It does not contain fine aggregate and is covered with a thin layer of cement on the surface of coarse aggregate. The slurry is bonded to each other to form a honeycomb structure with uniform distribution of pores, so it has the characteristics of air permeability, water permeability and light weight, and can also be called drainage concrete. Permeable concrete allows rainwater to flow into the ground, effectively replenishes groundwater, and alleviates some urban environmental problems such as the sharp drop in the city's groundwater level. At the same time, it is an excellen...
