In the present invention, the measuring cylinder 34 is fixed on the frame fixing plate 22, the frame fixing plate 22 may be configured as a double-layer parallel structure, two ends of the frame fixing plate 22 are fixed on the frame 1, a plurality of fixing plate through holes 32 are distributed on the frame fixing plate 22, the fixing plate through holes 32 can be communicated with the measuring cylinder 34, and a protective sleeve 33 made of a flexible material, such as a rubber material, a silica gel material, etc., needs to be arranged between the double-layer frame fixing plates 22 to protect the connecting position of the measuring cylinder 34. In practice, the initial level of the measuring cylinder 34 should be lower than the lower frame fixing plate 22.
In the present invention, a top plate 24 parallel to the frame fixing plate 22 is disposed above the frame fixing plate 22, and the top plate 24 is connected to the frame fixing plate 22 through frame connecting rods 23 at both ends. An auxiliary cover rod body 30 is connected to the frame body fixing plate 22 through a guide shaft sleeve 28 in a threaded mode, a measuring cylinder cover plate 29 is connected to the bottom end of the auxiliary cover rod body 30, and a measuring cylinder cover plate sealing ring 25 can be arranged on the periphery of the measuring cylinder cover plate 29. Auxiliary cover through holes 31 formed by a plurality of through holes are distributed on the measuring cylinder cover plate 29. When graduated flask apron 29 stretches into to vector section of thick bamboo 34 under the effect of supplementary lid body of rod 30, can avoid the water in the graduated flask 34 to take place rocking in the great scope at support body 1 removal in-process, and supplementary lid through-hole 31 can be convenient for graduated flask apron 29 and graduated flask 34's relative motion, avoids producing the suction phenomenon.
When the device is used, the whole device can be moved by the universal wheel assembly 16 extending out of the supporting leg 2, and when the device is moved to a test point, the universal wheel assembly 16 is collected into the supporting leg 2. The process of receiving the universal wheel assembly is carried out synchronously to ensure the stability of the whole device. Meanwhile, the structures of the measuring cylinder auxiliary cover sealing ring 25, the measuring cylinder cover plate 29, the auxiliary cover rod body 30 and the like are adopted in the moving process, so that the water body in the measuring cylinder 34 is ensured not to excessively shake, and the accuracy in observation is improved.
Before the measurement is started, the base cover 14 needs to be connected with the measuring cylinder connecting pipe 35 at the lower end of the measuring cylinder 34 through a hose so as to realize that the water in the measuring cylinder 34 enters the base body 40. Circle marks are drawn on the cleaned road surface by chalk according to the size of the base cover body 14, the lower edge 41 of the base body 40 is tightly attached to the road surface, and water cannot flow out from a gap or a seam between the lower edge 41 and the road surface.
1200mL of liquid is poured into the cylinder 34, and for the purpose of facilitating observation, a color-developing component may be added to the liquid, for example, the liquid may be developed in a pale red color. At the same time, the switch at the bottom of the measuring cylinder 34 is quickly opened, so that the liquid enters the base body 40 through the hose, when the water level drops by 100mL, the stopwatch is immediately started, and the scales in the measuring cylinder are recorded once every 60s until the liquid level drops by 1100 mL.
If liquid seeps from the connection between the lower edge 41 and the road surface during the test, the adjustment of the position of the base body 40 by the adjusting mechanism in the above paragraph is required to select a more flat road surface among the nearby road surfaces for the determination of the permeability coefficient. The above-mentioned only carries out the fine setting of base body 40 position, if need change the test point, then need carry out holistic removal through the universal wheel assembly 16 that landing leg 2 stretches out. In order to reduce the possible leakage situation, the invention reduces the leakage probability and improves the testing efficiency by redesigning the structure of the base body 40.
If the water surface descending speed is slow, the water seepage quantity can be stopped after the water surface descends to 100mL after the water surface is measured for 1 min. If the surface of the water remains substantially immobile after the surface has dropped to a certain extent during the test, indicating that the pavement is substantially or not permeable to water, it is noted in the report. And 6 side points are selected from the same detection road section according to the steps to measure the water seepage coefficient, and the average value is taken as the detection result. If the first reading is taken, the scale (mL), usually 100mL, is recorded as V1(ii) a The second reading is taken at a scale (mL), typically 1100ML, and denoted as V2(ii) a The water permeable area (mm 2) is marked as A; recording the time interval(s) when the water surface is lowered from the scale of 100mL to 1100mL as t; recording the water permeability coefficient (mm/s) of the pavement as P; the calculation formula of the road surface water permeability coefficient should be
。
If 1 of the 6 measurement points is impermeable, the other 5 measurement points are taken as the permeability coefficient of the measurement area; if 2 measurement points are impermeable, taking 2 points again for measurement; if 1 measuring point is still impermeable, the road surface water permeability of the measuring area is not qualified; if 3 measuring points are impervious to water, the road surface water permeability of the measuring area is not qualified.
Finally, although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description of the present description is for clarity reasons only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
