Embodiment
With reference to the accompanying drawings and examples, embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to scope of the present utility model.
It is the analogue means of the determination with vegetation bank stability of the utility model one embodiment referring to Fig. 1, including water
Case 1, water inlet 2 and delivery port, Zinc fractions riverbank with a slope is entered in the middle berth of water tank 1, is planted and is planted on riverbank with a slope
Quilt, such as, can sow grass-seed on the soil completed, and be tested again after draft when grass-seed grows.In the side of water tank 1
Top is provided with water inlet 2, and oral siphon 6 accesses water tank 1 by water inlet 2, flowmeter 7 is connected on oral siphon 6, in water tank 1
Bottom be provided with delivery port, be provided with corresponding valve 5 on delivery port.
Altitude scale is disposed with the side of water tank 1 and angle index is tilted, so that experimenter can be according on the side of water tank 1
Altitude scale and angle index is tilted to build the bank slope of preset height and predetermined inclination angle, form the inclination river of certain slope
Bank, to simulate true riverbank.
Wherein, dividing plate 3 is additionally provided with inside water tank 1, water tank 1 is divided into two parts space by dividing plate 3, wherein, first
Segment space arranges riverbank with a slope, and Part II space is vacant, and jagged 4 are set at the top of dividing plate 3.Water inlet 2 is set
The side top of water tank 1 in Part II space is disposed adjacent to, oral siphon 6 is noted by water inlet 2 to the Part II space of water tank 1
Flowmeter 7 on water, oral siphon 6 controls the flow of water filling, is not impulsive force during the water filling into water tank 1 too big.When water tank 1
Water level in Part II space increases to certain altitude, and water can flow into the Part I of water tank 1 from the breach 4 at the top of dividing plate 3
Water level in space, water tank 1 in Part I space is gradually increasing, and records water level rise speed.When the Part I of water tank 1 is empty
Between water level increase to certain altitude, open the valve 5 of the bottom of water tank 1, water discharged from the Part I space of water tank 1.This
Embodiment sets dividing plate 3 in water tank 1, and the whole space of water tank 1 is divided into the simulation band gradient in two parts, a part of space
Riverbank, another part space is vacant, and water first injects that vacant a part of space, then is flowed into from that vacant a part of space
To having in the space with gradient riverbank, it thus is avoided that and directly enters water into band gradient riverbank space, impulsive force is excessive causes band slope
Spend riverbank moment avalanche.
Water tank 1 and dividing plate 3 in the present embodiment use transparent plastic, so that testing crew can pass through transparent modeling
Material observes whole process of the test.
Wherein, the delivery port of the bottom of water tank 1 has multiple, and this multiple delivery port is arranged on the bottom in the Part I space of water tank 1
Corresponding valve 5 is provided with portion, each delivery port, can be by opening the valve 5 of varying number come regulating tank 1 first
During the fall off rate of the water level divided in space, the water level decreasing in the Part I space of water tank 1, under record water level
Reduction of speed rate.Wherein, during the water level in whole water tank 1 goes up and declined, the riverbank with a slope of growth vegetation at any time may be used
Can occur avalanche, scale and the time of bank slope collapse can be recorded, wherein can be by recording the soil volume of bank slope collapse
To record the scale of bank slope collapse with a slope, and then according to water level rise speed and drawdown rate of water level, Yi Jisheng in water tank 1
The avalanche scale on the riverbank with a slope with vegetation and time, to study the index of correlation, such as, water level rise speed is with
Reduction of speed rate and bank slope collapse scale with a slope and the relation between the time.The analogue means provided in the present embodiment can also be used
To study the rule for the bank slope collapse with a slope for not growing vegetation, by the rule of the bank slope collapse with vegetation and without vegetation
The rule on riverbank carries out comparative study, and the research for hydraulic engineering field provides support.
The analogue means set up in the present embodiment is used to carry out the process of stream bank stability Journal of Sex Research for by oral siphon to water
The Part II space water filling of case, with the rise of water level, water flows into the Part I space of water tank from the breach at the top of dividing plate,
Wherein, be equipped with the Part I space of water tank in riverbank with a slope, the Part I space of water tank the rise of water level and
The decline of water level can cause the avalanche on riverbank.When injecting water into the Part I space of water tank, the Part I for recording water tank is empty
Between in water level rise speed, when the Part I space water level of water tank goes up to a certain extent, by opening water tank bottom
Valve carries out draining, wherein, the valve of water tank bottom has multiple, can be adjusted by opening the valve of varying number under water level
During reduction of speed rate, the water level decreasing in water tank, the speed of water level decreasing in the Part I space of water tank is recorded.In water
During water level raising and lowering in the Part I space of case, the rule of the bank slope collapse with a slope of record growth vegetation
Mould and time, so as to study water level rise speed, influence of the drawdown rate of water level to bank slope collapse, water level rise can be drawn out
The scale and the relation curve between the time of the bank slope collapse of speed, drawdown rate of water level and growth vegetation, are that hydraulic engineering is ground
Study carefully field and support is provided.
Analogue means of a kind of determination with vegetation bank stability that the utility model is provided, by setting up analogue means,
For simulating as water level goes up and declines, the avalanche process with vegetation riverbank, to study water level rise speed, water level decreasing speed
