Abstract
The utility model provides a simulated diving seepage flow hysteresis's test device. The device is mainly by seepage flow pipe, resistance tube, pressure -measuring pipe, a plurality of three - way interface, water tank, tap to and the valve is constituteed. Wherein resistance tube effect slows down rivers, and the velocity of flow that makes its simulation equals the slow velocity of flow of submarine permeation fluid in the reality. Before on -test, making each instrument middle water level reach a take the altitude through the water inlet, then increasing the height of water level in the water tank of one side, the response that the water level in the different pressure -measuring pipes increases is observed to the instantaneous valve of opening the water tank lower part to this comes the simulation because the phreatic table rising causes water level hysteresis, provides the scientific basis for the research of submarine permeation fluid hysteresis law.
Description
Technical field:
The utility model relate in a kind of simulated dive water-bearing zone due to somewhere water level rise or decline, will the test unit that there is hysteresis phenomenon in the water level process of rising or falling of other positions in water-bearing zone be caused.
Background technology:
About in the research of area between rivers and diving well stream in groundwater dynamics, the hysteresis quality due to submarine permeation fluid causes its research to become increasingly complex, and the water even in some research directly in hypothesis water-bearing zone is instantaneous relase, there is not hysteresis phenomenon.So the authenticity and integrity in order to study, be necessary to carry out the delayed research of submarine permeation fluid.
As far back as 20 century 70s, electric power integraph has been widely used in the research of diving hysteresis phenomenon, but it by computer display screen being observed this phenomenon, can only lack necessary being sense.Therefore in this test unit, its simulation with comparatively close by the physical essence simulated, and tested by reality and reflect hysteresis phenomenon, show not by display screen.Also make the result of observation more vivid, also easy to understand.
Utility model content:
The purpose of this utility model is to provide a kind of test unit of simulated dive seepage flow hysteresis phenomenon, for some groundwater dynamics researchs provide scientific basis.
A test unit for simulated dive seepage flow hysteresis phenomenon, comprises seepage flow pipe, resistance tube, piezometric tube, some three-way interfaces, water tank, water swivel, and valve composition, and the connection of its each several part is mainly: described seepage flow pipe is between every two resistance tubes; Described piezometric tube is positioned at the middle part of seepage flow pipe, utilizes three-way interface, is connected a piezometric tube in vertical direction; Described water tank is positioned at the seepage flow pipe place of both sides, and water tank bottom utilizes seepage flow pipe to be connected by three-way interface with the seepage flow pipe in horizontal direction; Described water swivel is positioned at above the water tank of left side, and installs a by-pass valve control on the seepage flow pipe of water tank bottom.
Described resistance tube main body is the hollow circular-tube of " Y " type, inside have one can up-down adjustment, one end is fixed with the threaded drillpipe of the solid cylinder of certain length, only be connected by internal and external screw thread between threaded drillpipe with " Y " type hollow circular-tube, by twisting adjusting position, control current by flow velocity during resistance tube.
The beneficial effects of the utility model are: (1) increases resistance tube, by regulating resistance tube to make the water velocity in seepage flow pipe be equal to water velocity in real underground latent water, make the result of simulation truer; (2) utilize water swivel to increase Water in Water Tanks position, side height, the instantaneous valve opened below water tank, current, in flow event, by the hysteresis phenomenon observing the water level response in different piezometric tube represent diving, make result more directly perceived.

Embodiment:
Below in conjunction with accompanying drawing, the utility model performance is described:
The utility model is a kind of test unit of simulated dive seepage flow hysteresis phenomenon, comprise seepage flow pipe 1, resistance tube 2, piezometric tube 3, some three-way interfaces 4, water tank 5,6, water swivel 7, and valve 8,9,10 forms, the connection of its each several part is mainly: described connects a seepage flow pipe 1 between every two resistance tubes 2, and namely resistance tube 2 current import and export place respectively connects a seepage flow pipe 1; The middle part of the described seepage flow pipe 1 between every two resistance tubes 2, utilizes three-way interface 4, connects a piezometric tube 3 in vertical direction; Described respectively has individual water tank 5,6 at seepage flow pipe 1 place of both sides, utilizes seepage flow pipe 1 to be connected by three-way interface 4 with the seepage flow pipe 1 in horizontal direction bottom water tank 5,6; Water swivel 7 above described left end water tank 5, can provide water yield supply to water tank 5, the seepage flow pipe 1 bottom water tank 5 is provided with a valve 8; The main body of described resistance tube 2 device is the hollow circular-tube 11 of " Y " type, inside have one can up-down adjustment, one end is fixed with the threaded drillpipe 13 of the solid cylinder 15 of certain length, only be connected by screw thread 14,17 between threaded drillpipe 13 with " Y " type hollow circular-tube 11, regulate button 12 by twisting, control current by flow velocity during resistance tube 2.
The utility model experimental provision embodiment is:
Before test, first resistance tube 2 is regulated, adjustment button 12 on threaded drillpipe 13 in turn resistance tube 2, change the position of solid cylinder 15 in pipe bottom threaded drillpipe 13, thus change the speed of this resistance tube 2 that current pass through, its water velocity is reached and can start to test with the water velocity of true middle underground water underwater swimming.This process need slowly regulates, and makes its result have more representativeness.
In test, then open the valve 8 of water inlet, valve 9, valve-off 10, treat that water is full of whole device, the static level now in piezometric tube 3, water tank 5,6 is all h
