In order to better simulate the actual conditions of the engineering, in this embodiment, two sets of water delivery systems are designed, and two water delivery pipes are respectively located at two sides of the lock chamber 8. Each water conveying pipeline is connected with a three-way switching valve I10 at the upstream gate head 7, one joint of the three-way switching valve I10 is communicated with the upstream navigation channel water tank 3, and the other two joints are respectively communicated with a centralized water conveying pipeline 22 leading to the gate chamber and a distributed water conveying pipeline 11 leading to the side wall of the gate chamber; each water pipe is connected with a three-way switching valve II 10 at the downstream gate head 9, one joint of the three-way switching valve II 10 is communicated with the downstream navigation channel water tank 4, and the other two joints are respectively communicated with a distributed water pipe 11 leading to the side wall of the gate chamber and a centralized water pipe 22 leading to the gate chamber.

Distance measurement values can be marked on the side wall of the lock chamber 8 along the length direction to observe and record the water filling time and the water flow fluctuation range and degree of the lock chamber under different water delivery systems with different water heads. When the centralized water delivery system works, the length change of the calming section caused by the inflow and outflow of the sluice chamber 8 is observed and recorded, so that the purpose of an experiment is achieved.

(1) and adjusting a ball float valve 5 of the upstream approach channel water tank 3 to set a water level, opening a water inlet pipe valve 20 of the side first-level water storage tank 14, and storing water in the side first-level water storage tank 14 to a limit water level. The water in the side position first-level water storage tank flows into the upstream approach channel water tank 3 through the ball float valve 5, and the upstream approach channel water tank 3 stores water to a set water level line through the ball float valve 5.
(2) And (3) selectively opening a centralized water delivery system valve of the three-way switching valve I10 at the upstream gate head 7, enabling water to flow into the gate chamber 8 through a centralized water delivery pipeline 22 arranged at the upper gate head 7, filling water into the gate chamber, and observing and recording the water filling time, the water flow fluctuation range and the water flow fluctuation degree of the gate chamber.

And (3) selectively opening a centralized water conveying pipeline valve of the three-way switching valve II 10 at the lower gate head 9, discharging water in the gate chamber, and enabling the water to flow into the downstream navigation channel water tank 4 through the centralized water conveying pipeline 22 of the lower gate head 9.
(4) When the water level of the lock chamber 8 is reduced to be level with the downstream water level, the valve of the centralized water conveying pipeline at the lower lock head 9 is closed. So as to complete the observation and record of the water filling time, the water flow fluctuation range and the length of the calmed section of the gate chamber at a certain upstream water level line (forming a certain water head with the gate chamber water level).
(5) When the distributed water delivery system is adopted, the operation is carried out according to the steps, the difference is that the valves of the distributed water delivery pipeline of the three-way switching valve I10 at the upper gate head 7 and the valves of the distributed water delivery pipeline of the three-way switching valve II 10 at the lower gate head 9 are selected to be opened and closed, the gate chamber water charging and discharging process of the distributed water delivery system is realized, the gate chamber water charging time, the water flow fluctuation range and the water flow fluctuation degree are observed and recorded, and the comparison is carried out with the operation condition of the centralized water delivery system.
