The invention relates to the technical field of
civil engineering materials testing, in particular to a multifunctional linkage device integrating
sewage time-sharing sampling and
permeation coefficient testing and a working method of the multifunctional linkage device. The device mainly comprises two parts, wherein a first part is a device A and mainly comprises a power supply channel, a cylindrical overflow port, a water cylinder, an overflow water tank, a water tank overflow port, a
test sample bracket, a
test sample, a dial gauge, a
sewage sampling
pipe, a high-precision flow gauge, an electronic
thermometer, a working table I and the like; a second part is a device B and mainly comprises a working water bucket, a water draining bucket, a
propeller, a water pump, a power switch, a water pump electronic control
assembly, a
propeller electronic control
assembly, a guide rod rotation driver, a working table II and the like; the device A and the device B are connected through one
water supply guide
pipe and two water draining guide pipes, and accordingly, the multifunctional linkage device is formed. Therefore, the condition of
sewage permeation of a
porous pavement in a real environment can be simulated, samples of sewage filtered by the
test sample are obtained at different moments, the
permeation coefficient of the test sample is tested simultaneously, the water resource is recycled, and the operation is simple.
