Low-weir high pneumatic landscape gate construction method and structure

Abstract

The invention discloses a low-weir high pneumatic landscape gate construction method and structure. The method includes: a low overflow weir structure is adopted to guarantee silt and flood discharge capacity of riverway; a group of pneumatic gates is disposed in the width direction of the overflow weir 1, every two pneumatic gates are connected through intermediate seals 5 so as to form the integral gate weir; the whole group of the pneumatic gates of the integral gate weir is opened and closed synchronously, and riverway upstream water level is controlled by lifting the gate weir so as to satisfy the landscape requirements. The gates are of a shield-shaped stainless steel structure and novel and attractive; multistage water gate combination can be adopted without being limited by riverway width, wide application range is achieved; structures such as gate piers and support piers which influence the landscape are not needed in the riverway, and simple appearance is achieved; double-air-bag lifting is used as turning power, environmental protection, energy conservation and low carbon are achieved, and double-air-bag turning is stable; limit strips are used to limit strokes and excessive operation of the gates, safety and reliability are achieved, and the low-weir high pneumatic landscape gate can be in linkage with systems such as a water level monitoring system for automatic adjusting and control.

Description

technical field [0001] The invention relates to a construction method and structure of a pneumatic landscape gate with a low weir and high gate, and belongs to the technical field of water conservancy engineering. Background technique [0002] With the continuous improvement of people's material living standards, people's yearning for living environment and urban landscape is also increasing. In the past 10 years, many landscape sluices have been built in China and our province to raise the water level of urban rivers, create urban water landscapes, and improve the urban water environment. Most of the landscape sluices that have been built in our province are hydraulic automatic control The slab gate uses the water level difference between the upstream and downstream of the gate to automatically turn the gate to open the flood discharge during the flood period. After the flood period, the gate is automatically turned back by its own weight to store water and form a river lan...

Problems solved by technology

However, there is a certain difference between the design theoretical calculation value and the actual water flow situation, and the debris entrained in the water flow cannot be controlled, which often blocks the rotating part of the gate. In addition, the operation management and maintenance are inconvenient, so that the hydraulic automatic control flap gate operates Difficult to open and close normally after a certain number of years
