The device of the utility model is characterized in that a spring cushion and a bearing plate are mutually pressed to seal a sample and provide the required normal pressure; a flowmeter with a valve adjusts different hydraulic gradients and reads water flow; a balanced reservoir keeps stable water head difference; a booster pump can recycly use testing water to keep in line with room temperature and be free from the change of the climate of seasons. The device has the advantages of standard requirement, convenient operation, simple calculation and high accuracy.
Description
The utility model is under a kind of hydraulic gradient in regulation, the different normal pressure, the pick-up unit of discharge in geotextile and the relevant product plane thereof.
At present, domestic geotextile and the relevant product plane water-flowing amount measurement mechanism thereof that does not still have unified standard.There are many defectives in some homemade measurement mechanisms more.HFT-1 type horizontal permeation instrument with Henan Inst. of Textile's development is an example, and its major defect is: a, this instrument only provide 0.1 and 1.0 liang of gradient, but needs multiple different gradient in the practical application; B, cloth specimen grasping system are all used bolt, and its bolt has 10 more than, and is cumbersome, and sealing property is undesirable; C, because of its test water directly from tap water, so stable differential water pressures can not be provided, water temperature can not be effectively controlled; D, flow survey and read to adopt graduated cylinder and stopwatch, and be cumbersome and error is big.
To be that design is a kind of can satisfy multiple normal pressure and hydraulic gradient, easy to operate, geotextile that degree of accuracy is high and the pick-up unit of the horizontal water-flowing amount of relevant product thereof to the purpose of this utility model.
The utility model mainly is made up of tank, water inlet pipe, rising pipe, sample cushion cap, bearing plate, in rectangular base plate both sides is respectively water inlet pipe and rising pipe, base plate is owing to want holder pressure, so make with corrosion resistant plate, tank can be with materials such as organic glass, and the then available plastic flexible pipe of water pipe is put a rectangle sample cushion cap on base plate, leave certain distance between cushion cap and the tank and be convenient to the arrangement of elastic sealing gasket, the inlet tube and outlet tube symmetry.Can place testing sample on the sample cushion cap, be bearing plate waiting on the test sample product position then, and during pressurization, press device (as lifting jack) directly acts on bearing plate.Elastic sealing gasket two lays respectively on the bearing of inlet tube and outlet tube inboard, and this bearing and tank are fixed, and should be noted that cushion not seeping water between sample cushion cap and bearing plate all around.During test, after sample clips, utilize the extruding of bearing plate and cushion that sample is sealed in the current road, and provide normal pressure by press device, structure like this, the stream of water just passes through sample to be tested between sealing gasket and cushion cap.
If at bearing plate underlying one latex film, then the system sealing can be better.
The water inlet pipe water system of the utility model design is provided by balanced reservoir, and the flowmeter of a band valve is arranged therebetween, and not only scalable flow but also required hydraulic gradient can be provided promptly gets the result with the flow value data substitution formula of measurement device.Balanced reservoir makes water-head stable, and water temperature is consistent with room temperature, can not change with season.
For making cycling use of water, the utility model connects a cistern with the pick-up unit effluent pipe mouth, and cistern is connected with balanced reservoir by water pipe, with pump the retaining pool inner water is got to balanced reservoir and recycles.Cistern is put a rising pipe that leads to balanced reservoir in addition, so that water is got back to cistern in the balanced reservoir.
Cistern is provided with two holes, i.e. inlet opening and weep hole, and the inlet opening is for adding water before the test, and weep hole is for draining after the off-test.
This device can be used for discharge test in the plane of geotextile and Related product thereof, as drain bar, geotextile, geosynthetics product etc., can record the horizontal permeation coefficient and the hydraulic conductivity of such material by fortran.
The utility model adopts elastic sealing gasket and bearing plate to press composition sample holder part mutually, water pipe, balanced reservoir are as the water source part is provided, adding flow control and cycling use of water again, to have formed structure simple and clear, easy to operate, calculate simple and direct, the pick-up unit of geotextile that degree of accuracy is high and the horizontal water-flowing amount of relevant product thereof.This device has remedied the deficiency of existing this quasi-instrument, and for the detection of improving geotextile and relevant product water-flowing amount thereof provides testing tool, high-precision test makes the standardization of such detection that assurance is provided.
