Summary of the invention
In order to overcome the existing deficiency of pavement seepage instrument of the prior art, the utility model provides a kind of infiltration coefficient that can automatically detect bituminous pavement, the reliable Novel road-face creepage instrument of testing result.
The technical scheme that solves the problems of the technologies described above is: the pavement seepage instrument comprises chassis and the support that is fixed on the chassis, bottom surface on the chassis is provided with cavity, top at cavity is processed with water hole, T-shaped pipe is installed on the water hole, the coaxial arm end of T shape pipe and water hole is provided with vent valve, another arm is communicated with the water delivering orifice of electromagnetic flowmeter, at support tank is installed, Programmable Logic Controller and flow registering instrument, the water delivering orifice of tank is communicated with the water inlet of electromagnetic flowmeter by adapting pipe, electromagnetic flowmeter links to each other with flow registering instrument with Programmable Logic Controller respectively by wire, and Programmable Logic Controller links to each other by wire with flow registering instrument.
Above-mentioned cavity is taper shape or spherical crown shape.
The water inlet aperture of above-mentioned electromagnetic flowmeter is greater than the water outlet bore.
Above-mentioned electromagnetic flowmeter is to be horizontally disposed with.
Pavement seepage instrument of the present utility model is to have set up electromagnetic flowmeter by the output pipe at tank, detect and data on flows is stored in the flow registering instrument in good time by the Controlled by Programmable Controller electromagnetic flowmeter, demonstrate testing result by flow registering instrument, testing process can be controlled detection automatically, personal error is little, and testing result accurately and reliably, and is and relatively stable, whole apparatus structure is simple, and is easy to operate.
