In one example, before the step of launching the equipment, the bottom of the dam on two sides of the breach of the dam is cleaned and leveled through the amphibious excavator, and the pile can be sunk for reinforcement, so that the equipment can be conveniently abutted and subsequently operated.
In one example, in the rotating step of the buoyancy tank 1, the ropes can be installed at the maximum rotating radius of the buoyancy tank 1 and released gradually, and the buoyancy tank 1 is rotated at a constant speed by matching with the propeller 6.
In one example, if the length of the buoyancy tank 1 is less than the length of a breach or weak dam, a plurality of devices are combined and then the combination is launched.
The working principle of the invention is as follows:
aiming at the difficult problems of narrow operation space, poor foundation stability, strong turbulent water flow drag force, large water depth, continuous scouring and the like faced by the dam breach plugging, the invention utilizes a numerical simulation analysis means to assist in determining a plugging construction scheme and supporting measures aiming at the typical breach plugging situation.
According to the characteristics of hydraulic boundary of the levee breach, the characteristics of surrounding environment and the technical points of breach plugging, amphibious multifunctional plugging equipment is developed, a floating platform module of an overwater operation platform can be quickly assembled, and a breach quick plugging and safety guarantee complete technology and a matched plugging construction process are formed through modular construction, reliable connection, land transportation, overwater navigation control, overwater anchoring stability and quick carrying and tying of emergency equipment. The invention is suitable for the operation in the deep water with the depth of more than 5 meters.
The working process of the invention is as follows:
the invention can work in series depending on the width of the dam to be reinforced or breach. For example, a breach width of 7 meters and a buoyancy tank 1 width of 6 meters can be connected in series by two devices to form a 12-meter combination.
After the floating box is placed in water, the floating box can navigate to a designated position through the propeller 6, after the floating box 1 is vertically and stably stopped with a dam, the auger drill of the rear supporting frame 2 is inserted into the river bottom to form a rotating supporting point, the floating box 1 is rotatably abutted against the dam through the rotating supporting point, and in order to avoid the influence of turbulent water flow, the stability of the rotating process is ensured through the propeller 6 and the traction rope.
The buoyancy tank 1 is turned over to form primary plugging, and the water flow on the upper part is plugged by the buoyancy tank 1. Through the detected water depth, when the water depth is larger than the length of the baffle 4, the maximum stroke of the inserting plate 5 and the water inlet depth of the floating box 1, the water inlet 7 is opened, the floating box 1 sinks, and the water inlet depth of the floating box 1 is improved. For example, the water depth is 6 m, the width of the baffle 4 is 2.5 m, the maximum stroke of the inserting plate 5 is 2.5 m, the water inlet depth of the buoyancy tank 1 is controlled to be more than 1 m, the water inlet depth of the buoyancy tank 1 is increased through a water inlet, and the water inlet depth can be reduced through water pump drainage.
Then the auger of another back fulcrum frame 2 is also bored and inserted into the river bottom, and preceding balanced support 3 descends and contacts with the river bottom, forms stable four point structure, avoids buoyancy tank 1 to topple forward when follow-up baffle 4 overturns. After the cell plates on the two sides of the baffle 4 are turned over for 90 degrees, the cell plate in the middle is turned over to form middle section plugging.
Because the bottom of the river is uneven, the terminal plugging formed by the baffle 4 can not completely cut off the water flow, and the bottom of the opening can be scoured at a high flow rate according to the Pascal law, so that the construction of a dam is influenced. Therefore, the combined plugboard 5 descends and is spliced according to the river bottom depth, when the plugboard 5 is spliced, the descending depths are different, final plugging is completed, and water flow is completely cut off. At the moment, the dam is strengthened or the breach is blocked, the breach can be built, after the building is finished, the inserting plates 5, the baffle plates 4, the front balance supports 3 and the rear fulcrum supports 2 are withdrawn in the opposite sequence, and the floating box 1 is recovered or enters the next to-be-strengthened or breach.
In conclusion, the invention can gradually cut off the water flow at the weak part or the breach of the dam in a remote control mode through primary, middle and final three-stage plugging modes, and has the advantages of higher working efficiency, reliability, stability and more flexible use.
