Tide gate double-gate system and construction method thereof

Abstract

Provided are a tide gate double-gate system and a construction method thereof. The system comprises a main gate system and an auxiliary gate system with a one-way water passing function. The auxiliarygate system is connected with the main gate system. The auxiliary gate system comprises an auxiliary gate frame, a side hung gate, a water passing hole and a flap valve. The auxiliary gate door is fixed to a lock chamber overflowing channel, the side hung gate is mounted on the downstream face of the auxiliary gate frame, the water passing hole is formed in the side hung gate, and the flap vale is hinged to the downstream face of the overflowing hole. The construction method comprises the steps that the main gate system is mounted; the auxiliary gate frame and the side hung gate are welded and assembled, the water passing hole is formed in the side hung gate, and the flap valve is hinged; the auxiliary gate frame and the side hung gate are mounted through an auxiliary gate hoisting crane;and water is injected into an independent sealed space of the side hung gate to adjust the opening and closing pressure of the side hung gate. The main gate system specializes in drainage and riverway water level control, the auxiliary gate system specializes in blocking tide, the two systems share work and cooperate, and the problem that water resource regulation and control and water environment and ecological management are hard to combine is solved.

Description

technical field [0001] The invention relates to the field of sluice gates, in particular to a double-gate system of a tidal gate and a construction method thereof. Background technique [0002] The tidal gate is a control project for inland rivers to enter the sea, and it undertakes various tasks such as water supply, tide blocking, flood drainage, and waterlogging. In the rainy season, in order to discharge floods and reduce waterlogging, the tide gates need to be opened and closed according to the tides day and night to catch and drain waterlogged water. High cost; in dry seasons, in order to improve the utilization rate of water resources and reduce project management costs, the set water level is often used as the trigger pointer for gate regulation, and the tide gate project is controlled by means of large flow in certain periods of time and closed gates in other periods of time, resulting in The river has been dry for a long time. [0003] The above-mentioned traditi...
