Description

Pneumatic telescopic shield-shaped gate

Technical Field

The utility model belongs to a pneumatic shield-shaped gate, in particular to a pneumatic telescopic shield-shaped gate.

Background

The pneumatic shield-shaped steel gate is a new type of dam which integrates the advantages of traditional steel gate and rubber dam, and is mainly characterized by that it is a combined structure, and is applicable to hydraulic engineering with different spans, and has no need of dam pier connection, and especially possesses absolute advantage in the large-span, low-head and compact-arrangement gate dam engineering, and it not only can meet the functional requirements of conventional gate, but also can be coordinated with peripheral environment, and can fully meet the requirements of ecological and landscape of modern hydraulic engineering, so that it not only can be used for river channel and reservoir, but also can be used for heightening and widening of seawall, artificial landscape, diversion irrigation, drought-preventing and waterlogging-discharging and existent large dam. The pneumatic shield-shaped gate system mainly comprises a steel gate, an air bag, an embedded part, an air compression system and a control system. The air compression principle is utilized, and the air bag is inflated or exhausted to lift or collapse the gate. The specific water level height can be maintained, and the adjustment of any water level height in the designed water level can be realized.

At present, in the existing pneumatic shield-shaped gate, the water stopping of a water retaining shield plate and an end wall adopts a mode that L-shaped water stopping rubber is tightly pressed by a pressing plate, and the fixed water stopping structure can cause abrasion and deformation of the L-shaped water stopping rubber in long-term rising and falling operation of the water retaining shield plate, so that the problem of water leakage at the position of the end wall and the water retaining shield plate is caused, and the difficulty of manually replacing a water stopping piece is large because a river channel is in a water passing state. In addition, in the dam foundation construction stage, the problem that the shield plate cannot be installed due to the fact that the distance between the end walls is smaller than the minimum installation size of the water retaining shield plate due to concrete pouring and the like is solved, and the existing solution is to cut the shield plate or chisel off redundant end walls; however, cutting the shield plate will cause the corrosion-resistant layer of the shield plate to be damaged and affect the service life of the shield plate, and chiseling the end wall will increase the construction cost and affect the construction progress.

The applicant does not search the domestic patent literature reports which are the same as or similar to the patent application.
