Description

Double-leaf flap gate

Technical Field

The utility model relates to a hydraulic gate technical field especially relates to a double leaf flap gate.

Background

The gate is widely applied in fields such as flood control, drainage, impoundment, irrigation, and a lot of floodgates in coastal areas often compromise the function of keeping off flood (tide) and drainage, simultaneously along with the continuous improvement of people to environment, view requirement, a lot of river courses need to accumulate certain water level in order to satisfy view, ecological requirement, consequently a lot of floodgates still compromise the function of keeping inland river view water level. The water level change of the river flood (tide) outside the coastal area is large, and the navigation function is also taken into consideration, so that the scale of the gate is large, the landscape gate suitable for the function is mainly an upper horizontal gate or a lower horizontal gate at present, the gate is matched with a hydraulic hoist, the gate has no high-rise structure crossing the water surface, and the landscape coordination is good.

However, due to the use conditions, the gate of the type is huge in scale, the length of a gate chamber is far longer than that of a conventional water gate, the construction cost is high, the whole door body needs to be opened fully at each time, a large-capacity hydraulic hoist is easy to damage due to frequent opening and closing, the gate is easy to deform, the operation and maintenance cost is high, and even the situation that the gate of the type is abandoned due to high operation and maintenance cost occurs in some places.

At present, double-leaf doors are applied to traditional plane vertical lifting steel gates mostly, but no application case exists in flap gates. The existing flap gate is generally one gate, the size of the gate body is large, the width exceeds 10m, and the height exceeds 6m, the weight of the single gate often exceeds 30t, the occupation area of a gate chamber is far larger than that of a conventional sluice, particularly, the silt depth in coastal areas is large, and the lower part of the gate chamber needs to be treated by a foundation, so the civil engineering cost is far larger than that of the conventional sluice.

The tide water in the bead triangle area is half-day tide, namely, the tide water has twice tide rise and fall every day, and is influenced by the tide rise and fall, the water gate needs to be frequently changed between the tide blocking working condition and the water draining working condition, the gate needs to be frequently opened and closed, the service lives of the gate and the gate opening and closing machine are influenced, the installation and maintenance are inconvenient, and the management and operation cost is increased.

In most cases, the landscape water level in the gate needs to be maintained, the whole gate does not need to be opened, and the gate leaves below the landscape water level do not need to be opened.
