Along with the rising of water level in the regulation pond, the water in the regulation pond flows to the peripheral recharge canal of first recharge field piece prescription and second recharge field piece prescription along two delivery pipes respectively in, and the water level rises gradually in the canal.
When the water level in the channel at the periphery of the first recharging field block sample square rises to the buried depth of 0.8m, the switch of the second liquid level relay is opened, the electromagnetic valve is electrified, the valve is closed, and the regulating and storing pool stops supplying water into the recharging channel; and then the water level gradually decreases, when the water level decreases to the burial depth of 1.1m, the switch of the second liquid level relay is closed, the electromagnetic valve is powered off, the valve is opened, and the regulating and storing pool begins to supply water into the recharge canal.
When the water level in the channel at the periphery of the second recharging field block sample is increased to the buried depth of 1.3m, the third liquid level relay switch is opened, the electromagnetic valve is electrified, the electromagnetic valve is closed, and the regulating and storing pool stops supplying water into the recharging channel; and then the water level slowly drops, when the water level drops to the buried depth of 1.6m, the third liquid level relay switch is switched off, the electromagnetic valve is switched off, the valve of the electromagnetic valve is opened, and the storage tank starts to supply water into the recharge canal again.
4. After the test is operated for a period of time (4 hours are set at this time), a power supply switch of a second submersible pump in the pumping well is turned on. If the depth of water in the regulation pond is less than 10cm this moment, then the fourth liquid level relay switch of this second immersible pump is automatic to be opened, and the second immersible pump begins to supply water to the retaining in the regulation pond, and when the water level rose to 50cm in the regulation pond deeply, fourth liquid level relay switch broke off, and the second immersible pump stopped to supply water. If the depth of water in the regulation pond is greater than 10cm at this moment, then fourth liquid level relay switch still is in the off-state, and this second immersible pump does not supply water in to the regulation pond for a while.
5. In the long-time operation of experiment, if the water level reaches the gap position in the regulation pond, water flows out along the overflow pipe. When the water level in the storage tank drops to 10cm, the fourth liquid level relay switch is turned on, the power supply of the second submersible pump is switched on, water is supplied to the tank, and when the water level rises to 50cm, the fourth liquid level relay switch is turned off, and the second submersible pump stops supplying water.
6. After the operation is carried out for a period of time (48 h is set at this time), whether the water level burial depth in each water level monitoring pipe meets the test requirement burial depth or not is observed, if the actual water level burial depth is larger than the test requirement burial depth, the three signal wires in the peripheral channel are integrally and upwardly improved by a part, and if the actual water level burial depth is smaller than the test requirement burial depth, the three signal wires in the peripheral channel are integrally and downwardly moved by a part.
7. In long-term operation, the water level change condition in the recharge field sample is observed, and under the normal condition of the operation of other equipment, if the water level in the water level monitoring pipe is reduced to a certain extent (according to 20cm at this time), the filter material layer in the recharge canal is blocked. Three signal wires in the reinjection channel are taken out and placed in a water bucket, the signal wires are all ensured to be under the water surface, and the electromagnetic valve is in a closed state. When the water level in the channel is lowered to be close to the buried depth of 2m, a second submersible pump pipeline in the pumping well is connected to the backwashing pipe, the power supply of the submersible pump is switched on, water flows into the recharge channel along the backwashing pipe, namely the filter material layer, and the power supply of the second submersible pump is switched off after the water flow flowing out of the filter material layer is observed to be clear; and the second submersible pump pipe is connected and is placed back into the regulation and storage tank again, and the signal wire is placed into the recharge canal again according to the original specification.
Because the stratum lithology of each region is different, the quantity matching of the regulation pool with proper size, the recharge canal and the pumping canal needs to be determined according to the difference of pumping and recharging conditions, and generally, one pumping canal is matched with two recharge canals under the condition of the same scale and is more suitable

2. By utilizing the water level automatic control technology and taking the water level as a control index, the automatic transfer of the water quantity and the automatic regulation and control of the water level among the water pumping subsystem, the regulation and storage subsystem and the recharge subsystem are realized.
