Abstract
The invention relates to an automatic water level (water quantity) recording device, which is structurally characterized in that the automatic water level (or water quantity) recording device consists of a Mariotte bottle, a resistance wire, a floater, a valve, a lead and an ohmmeter (or the lead is connected to a digital acquisition instrument for automatic acquisition), wherein the floater (i.e. water level) ascends or descends in the Mariotte bottle to change the resistance value of the resistance wire, the dynamic change of the resistance value is monitored by the ohmmeter (or the digital acquisition instrument) so as to automatically record the water level or water quantity in the test process.
Description
Technical field
The present invention relates to a kind of automatic water level (or water yield) pen recorder, utilize this device to mend in drainage procedure at indoor open trial that ground is freezed, carry out the automatic record of dynamic water level or the water yield.
Background technology
When ground freezes, wherein moisture moves to freezing front, produces heavily to distribute and to form ice or ice sheet, make former rock-soil layer volume increase (or making surface uplift) thus produce frost heave, cause all kinds of building destructions; And the ground freezing is when melt, its ice or ice sheet become water, make former frozen soil rock volume reduce (or making land subsidence) thus produce inhomogeneous distortion, also will make all kinds of buildingss suffer destruction in various degree.
Summary of the invention
In view of above-mentioned, object of the present invention aims to provide a kind of automatic water level (water yield) pen recorder.At the indoor water level (water yield) that ground sample is being freezed to moisture supply in open trial process or excretion record automatically.This device mainly to ground sample in freezing open trial process, simulated groundwater is under the effect of capillary water, due to top soil freezing, reflection underground water is when move to permafrost region by melting soil layer, moisture supply in time or the situation of excretion.
The present invention is achieved through the following technical solutions:
A kind of automatic water level (water yield) pen recorder
,mainly by float, resistance wire, horse Liao Te bottle, air intake opening, rubber stopper, water inlet pipe and water outlet pipe, valve and resistance table or connection data Acquisition Instrument, formed.Rubber stopper is equipped with in horse Liao Te bottle top and bottom, and rubber stopper central authorities are equipped with water inlet pipe and water outlet pipe, and valve is housed on water inlet pipe and water outlet pipe, and sidewall has air intake opening, and resistance wire is connected with rubber stopper through float, and buoy upper resistance wire is connected with ohmmeter data collecting instrument by wire.
Advantage of the present invention:
This system mainly to sample in process of the test, simulated groundwater is under the effect of capillary water, due to top soil freezing, when underground water moves to permafrost region by melting soil layer, moisture supply in time or the situation of excretion, cause the lifting of float (being water level) in horse Liao Te bottle, will the resistance value of resistance wire be changed, by ohmmeter (or data collecting instrument), monitor it and change dynamically, thereby reach, in process of the test, automatically record water level or the water yield.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
[0008] as shown in Figure 1, a kind of automatic water level (water yield) pen recorder, is mainly comprised of float 1, resistance wire 2, horse Liao Te bottle 3, air intake opening 4, rubber stopper 5, paddle hole 6, valve 7 and ohmmeter 8 or connection data Acquisition Instrument.Rubber stopper 5 is equipped with in horse Liao Te bottle 3 tops and bottom, and sidewall has air intake opening 4, and bottom is provided with the water inlet pipe and water outlet pipe 6 that valve 7 is controlled, and resistance wire 2 is connected with rubber stopper 5 through float 1, and float 1 top resistance wire 2 is connected with ohmmeter 8 or data collecting instrument by wire,
Before on-test, the rising pipe of water charging system is connected with the water inlet pipe of test specimen base plate (pipe is interior without air), and the air intake opening 4 of horse Liao Te bottle 3 and the bottom face of test specimen are in same level.During on-test, open valve 7, the water in horse Liao Te bottle 3 can, under the effect of kapillary and thermograde, cover in sample at any time.In process of the test along with moisturizing or the excretion of sample, float 1 moves up and down in will or raising in the reduction of water level, float 1 top resistance wire 2 is connected with data collecting instrument 8 by wire, again data collecting instrument 8 is communicated with computer, open computer, enter data acquisition system (DAS), thereby the variation of resistance value between dynamic concept measuring resistance silk 2 A, B two ends reaches the object that automatically records water level or the water yield.
