When the demonstration instrument works, regional seepage can be solely displayed, or the phenomenon that the regional seepage and local seepage are iterated is displayed at the same time, related research is done, the range of groundwater drop funnel which is formed by the local seepage and the size of the water inflow of the underground chamber are predicted, and beginners are also helped to recognize.
Description
Technical field:
The present invention is local relevant with area interstitial flow demonstration instrument with underground water.
Background technology:
The most typical structure of underground water zone seepage flow motion state is the strong mountain area of landform cutting, underground water is supply source with the atmospheric precipitation, the supply water-bearing zone permeates the ground, underground water slowly moves to low-water level from high water stage, drain at locality cutting minimum river or cheuch at last, be cut to below the water table as inferior one-level cheuch, large-scale especially in the last few years fundamental construction, when the underground chamber of human engineering excavation (as the underground power house in power station, railway, the excavation in highway flint road) when entering the water-bearing zone, underground water in the certain limit will be drained by hand excavation's chamber, form new groundwater flow and excretion pathway, the particularly phreatic flow direction and original regional direction of groundwater flow are different fully, and this situation is phreatic local seepage flow; The generation of local seepage flow causes groundwater table decreasing; Form underground water and fall a funnel, cause surface well, spring to dry up the leakage of reservoir etc.Original groundwater environment is brought adverse effect.Can cause surface collapse, the gushing water of underground chamber when serious.Because point of release position and strength difference spatially form the state that shallow-layer local circulation and deep regions water cycle are repeatedly put.Local and the area interstitial flow situation of underground water is understood in people's digital simulations commonly used or hydroelectric analoguesi-mulation, the cost height, and not directly perceived.
Summary of the invention:
The objective of the invention is in order to provide more than one to state two cover water circulation systems is simulated object, during work, can represent area interstitial flow separately, or represent the phenomenon that area interstitial flow and local seepage flow are repeatedly put simultaneously, carry out correlative study, predict that the scope of a funnel and the size of underground chamber water yield fall in the underground water that local seepage flow forms, also can help the beginner to be familiar with and to understand the underground water part and the area interstitial flow demonstration instrument of the ABC of underground water part and area interstitial flow.
The object of the present invention is achieved like this:
Underground water of the present invention part and area interstitial flow demonstration instrument, include the casing of demonstration screen and water proof base plate, be positioned at casing parallel with demonstration screen and and demonstration screen and water proof base plate between form the seepage flow plate in narrow slit groove interstitial flow demonstration district, the width in narrow slit groove interstitial flow demonstration district is 0.5～2mm, a left side on the seepage flow plate relative with the demonstration screen, right both sides have the simulation chamber respectively, the area interstitial flow osculum, on one end and the chamber drainpipe that is connected of simulation chamber the chamber draining control valve is housed, zone drainpipe one end is connected with the area interstitial flow osculum, in casing, be positioned at place, narrow slit groove interstitial flow demonstration district clear water infiltration case is arranged, tracer agent infiltration case, on the seepage flow plate, have and some clear water is permeated case, the seepage flow hole that tracer agent infiltration case communicates with narrow slit groove interstitial flow demonstration district respectively, clear water service tank and tracer agent service tank are equipped with in casing top, the tracer agent pipe that supplies of the clear water feed pipe of the band clear water flow variable valve that is communicated with clear water service tank and tracer agent service tank respectively and band tracer agent variable valve provides clear water to clear water infiltration case and tracer agent infiltration case respectively, tracer agent, provide experimental water by clear water infiltration case that is arranged at top, interstitial flow demonstration district and tracer agent infiltration case, the vertical recharge of phreatic water of simulation atmospheric precipitation, by the minimum erosion basis of regional osculum simulated domain---the river that is arranged on the seepage flow plate, be the phreatic regional point of release, by the simulation chamber that is arranged on the narrow slit groove seepage flow plate, be the phreatic local point of release, simulate with tracer agent, the current trace is by each pipeline, each flowrate control valve, composition flow control system such as viewport and be that area interstitial flow or local and area interstitial flow represent simultaneously by this system may command interstitial flow demonstration district.
The cross sectional shape in above-mentioned narrow slit groove interstitial flow demonstration district is a rectangle.
The width in above-mentioned narrow slit groove interstitial flow demonstration district is 1mm.
The flow viewport is arranged, the tracer agent viewport on the above-mentioned casing.
On above-mentioned clear water feed pipe and the confession tracer agent pipe flow observation drop bottle is housed respectively.
Above-mentioned chamber draining control valve is contained on the casing, and is easy to operate.
The freeing port of above-mentioned regional drainpipe is lower than the height of tracer agent in clear water infiltration case middle water level and the tracer agent infiltration case, produces seepage flow under the effect of water-head.
Phreatic motion can not observe directly, need to understand by theoretical derivation and analysis, when the local seepage flow of underground water shallow-layer and deep regions seepage flow exist simultaneously, give theoretical derivation and analyze and bring very big difficulty, the beginner is beyonded one's depth.Demonstrator of the present invention is in order to represent the seepage flow feature that shallow-layer partial water circulation and deep regions water cycle are repeatedly put, and the simulation section is positioned a vertical hydrogeologic section along groundwater flow direction unanimity.Demonstrate the state that simulation just can clearly represent local seepage flow of shallow ground water and deep phreatic water area interstitial flow by the present invention, can be by the current trace that presents in interstitial flow demonstration district, the head line that waits of seepage field draws, and then draw drift net, the utilization drift net is analyzed phreatic water stream characteristics of seepage field and motion key element.
If the on-the-spot in the open air correlation parameter of obtaining the water-bearing zone, according to the principle of analog simulation, analogue formation, the size of prediction hand excavation chamber water yield, the scope (the drainage scope of shallow ground water) of a funnel etc. falls in the underground water that may form, to solve the relevant issues in the production practices.
The student can be familiar with at the local seepage flow of areal underground water and has the state of repeatedly putting mutually simultaneously by experiment, can learn to utilize narrow slit channel mould type, and the experiment of development and Design is for the problem that solves in the production practices is laid good basis.
