Lift type overflowing level control device

Abstract

The invention provides a lift type overflowing level control device. Steel plate piles and a river bank form a closed cofferdam. The lift type overflowing level control device also comprises a liftingmechanism, a gate and a container. A gap is formed in the cofferdam at each steel plate pile, and the container is placed in the gap. The two ends of the container are connected with the steel platepiles, and gate guide devices are arranged at the two ends of the top of the container are connected with the steel plate piles. A groove is formed in the top of the container between the two gate guide devices, and the gate is positioned between the two gate guide devices and the groove. The lifting mechanism is connected with the gate and is used for lifting up and down the gate. The container is arranged between the steel plate piles, and the plane of the upper surface of the container is used as a horizontal reference, so that the reference plane is conveniently leveled at the bottoms of different river bottoms. The gate and the gate guide devices can be mounted by the reference plane, and therefore the cofferdam has a good sealing effect.

Description

technical field [0001] The invention relates to the field of municipal river management, in particular to a lift-type overflow water level control device. Background technique [0002] With the country's continuous emphasis on river governance, river dredging, beautification, and water level control have become the focus of work. Due to the wide range of related projects in our country, it is necessary to provide low-cost, fast and convenient supporting facilities for related projects. It is very necessary, and it is also a problem that urgently needs to be considered. In the current related work, it is necessary to calculate the stability of embankments, earth-rock dam slopes or cofferdam slopes. It is necessary to calculate the safety factor and process it through a single safety factor. Due to the obvious defects of this method, it can be said that it is becoming more and more exposed. There are restrictive requirements on the difficulty of construction and the site, and...

AI Technical Summary

Problems solved by technology

[0004] However, the steel dam gate used for the overflow of the existing cofferdam requires a large amount of civil engineering work, and requires high precision and rigidity of the gate

In addition, the steel dam door occupies a large space, and the sealing requirements are strict, and leakage accidents may occur if there is a slight carelessness

Moreover, the steel dam gate can only be used as a permanent fixed facility, and cannot be easily dismantled and transferred as needed
