Description
Technical field
The invention belongs to research soil and water conservation device technique field, relate to a kind of device that is used to set up urban water-through surface water collection effect test, be that a cover is adapted to the rainfall simulation pilot system on road surface, city, the permeability that this device can the on-site measurement underlying surface obtains the related data that rainwater is collected.
Background technology
Construct the building element of urban water-through surface, all bigger as water-permeable pipe, pervious concrete piece equal-volume, obviously can't directly observe permeable infiltration effect with the instrument of routine observation soil infiltration rate; Generally speaking, fibrous root, designs special test unit and observes with reference to the measuring method of soil seepage rate according to permeable version.
At [Schl ü ter W such as Schl ü ter, Jefferies C.Modelling the outflow froma porous pavement.Urban Water, 2002,4:245-253] pass through underground drain, the parking lot of having observed a permeable brick lay, the infiltrate characteristic that to have obtained the different following operating periods of condition of raining be 20 months permeable brick flooring, and verified in view of the above in the fail-test of relevant mathematical model.Chen Yifan etc. [Chen Yifan, leaf put forth energy, Yang Yongping. determining and checking of Surface Infiltration Rate of Porous Sidewalk. road and traffic. Chinese municipal works, 2006, (1): 4-6] to impale water catchment area at the scene, walkway be 13.66m
2Test specification, with infiltration instrument the discharge water simulation and the method for rain controller rainfall simulation, measure the water yield in the depth of water at each place, reference mark of same time and the collector pipe, drawn during interlocking segment walkway face surface water infiltration rate tests.At [Ji Guixia such as Ji Guixia, Wang Wenyuan, Xu Xiangyang. urban rainwater infiltrates and the unwatering system experimental study. Shanghai University of Science and Technology's journal, 2003,25 (1): 72-76] and [Ji Guixia, Wang Wenyuan, Xu Xiangyang. the rainfall of permeable storm sewer infiltrates experimental study. the water conservancy journal, 2004, (2): 115-118] go into to blend permeable storm sewer model test by the earth pillar rainwater of pervious blanket face, to infiltration type rainwater utilization system carried out experimental study etc. a series of relevant rainwater infiltrate in the test, all related to rainmaking or runoff yield and measured.
Existing measuring system part all is directly to dig a hollow place afflux bucket or other devices to be put into wherein measured then in the test site; Rig for testing has the following disadvantages as can be seen from existing test unit: the rig for testing underaction is not easy to transportation and mobile; Because the status requirement of header tank need be a lot of with the test site excavation, and the test site is destroyed greatly, also reduced test efficiency simultaneously; Test generally needs big water gaging, and conventional device is bigger to water resource waste.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of device that is used to set up urban water-through surface water collection effect test.
Technical scheme of the present invention is as follows:
Device of the present invention mainly is made up of runoff measuring device, rainfall infiltration test face and three parts of rainfall simulator.
The runoff measuring device chief component is: afflux groove, afflux bucket, synchronous miniature immersible pump, runoff bucket, adjusting water control valve door, stopwatch etc.; Adopt synchronous miniature immersible pump that the afflux inner bucket water is flowed to draw water in the runoff bucket to make and keep afflux inner bucket water position stable, the flow of miniature immersible pump cooperates observation by stopwatch with the runoff bucket of mark level scale synchronously; The afflux groove is a semi-closed structure, to test face opening, can effectively stop test face rainwater in addition, improves the accuracy of test.
Rainfall infiltration test face is an abutment wall can insert the pull-out combined steel plate pile, is separated out the inspection surface of a dimensioning, prevents that this inspection surface from exchanging with underground water with rainwash outside the observation area; After the rainfall simulation off-test of battery of tests face, steel sheet pile can be extracted, and is provided with the back and reuses;
Rainfall simulator, this device comprise rainfall shower nozzle, adjustable flat bed and water system; Adjustable flat bed, whole framework is welded by angle steel; Base can regulate the lead screw adjusting level of height by three difference, makes it to be suitable for multiple hillside fields face; Water system mainly is made up of water control valve door, primary and secondary structure supply tank, A submersible pump and B submersible pump; The box frame of the female case of primary and secondary structure supply tank adopts bolt, and is detachable, and built-in three-ply board of tank wall and Polypropylence Sheet are to keep watertightness, and volume is big; Voltage stabilizing bucket volume as sub-case is less, places in female case, supplies water to rain controller with the water level that is maintained fixed.
Effect of the present invention and benefit are:
Rain controller is that base adopts bolt leveling mode to make, and is suitable for various domatic; Water system adopts the composite box structure; Wherein female case supply tank is formed by the angle steel bolt, and capacity is big, is convenient to dismounting and mobile, simultaneously sub-case voltage stabilizing bucket is placed the bucket that supplies water, and makes the water circulation utilization, using water wisely; The measuring system aspect adopts the transfer type mensuration, and afflux bucket diameter is that 15cm ground buried depth is 15cm, and excavated volume is very little, underlying surface is destroyed light; The miniature immersible pump size is little, cheap synchronously, the practicality height, and pump-out reaches testing requirements, the convenient and swift test of energy;
Use this device to make things convenient for and launch test rapidly in the city, measure permeable the permeability in city,, can withdraw rapidly after test is finished for the research of city underlying surface water collection effect provides corresponding data.Simultaneously can guarantee that minimum degree influences all round resident and environment.The device of this invention: the degree of accuracy height, the dirigibility height, water consumption is few, and cost is low, and is little to the surrounding enviroment influence.
