The invention discloses a device and method for measuring permeability coefficient of a permeable pavement on site, wherein the device comprises an annular fixing piece, a water collecting column, a rainfall spray head, a water supply system and a flowmeter; the annular fixing piece is sleeved and fixed on the side face of the lower end of the water collecting column, the bottom face of the annular fixing piece is flush with the lower end face of the water collecting column, the annular fixing piece and the water collecting column are both located on the permeable pavement to be tested, rubbersealing rings are arranged between the permeable pavement to be tested and the lower end faces of the annular fixing piece and the water collecting column, a plurality of balancing weights are placedon the annular fixing piece, the rainfall spray head is located in the water collecting column, the water supply system is communicated with the water inlet of the rainfall spray head through the flowmeter, and a plurality of overflow ports are axially formed in the side wall of the water collecting column. The device and method for measuring permeability coefficient of the permeable pavement onsite can be used for measuring the permeability coefficient of the permeable pavement on site.
Description
technical field [0001] The invention belongs to the field of civil engineering, and relates to a device and a testing method for measuring the permeability coefficient of a permeable pavement on site. Background technique [0002] In recent years, the construction of "sponge city" has become increasingly popular, and people's awareness of recycling rainwater has become stronger and stronger. As an important material for the construction of "sponge city" roads, permeable asphalt pavement and permeable cement concrete pavement are used more and more. There are more and more studies on the use of permeable asphalt and permeable concrete in scientific research institutions of various universities. As an important index in the research of permeable asphalt pavement and permeable cement concrete, the permeability coefficient occupies a very important position in the research. The existing regulations in our country only introduce and explain the method of measuring the permeabil...
