Spare water-blocking dam for segment fixation hole and seam leakage flashboard detachable automatic alarm switch gate

Abstract

This is a two sectional removable spare dam with drain slot on plates and an alarm system. In case of dam break, the alarm system on the spare dam alarms for evacuation and the plates are closed for slow drain via the slots to decrease lost.

Description

Technical field

[0001] The invention relates to a dam of a hydropower station, in particular to a backup dam which can be disassembled to automatically alarm and close the sluice with segmented, fixed holes and seams leaking at an appropriate position upstream of the reservoir of the hydropower station. Usually, it does not affect power generation, navigation, and ecological balance inside and outside the reservoir. However, in case the original dam of the hydropower station is bombed and collapsed, the siren can be sounded immediately and the ram will be closed at the same time. Remove the part of the water upstream of the standby dam that automatically alarms and closes the gate, so that it will not swarm down instantly with the out-of-control water head caused by the collapse of the original dam of the hydropower station, and become an accomplice to crimes. That part of water leaks out gradually through the slit of the standby dam and the slit of the standby dam that can au...

Embodiment Construction

[0017]First of all, apart from a certain safe distance upstream of the dam of the hydropower station, and taking into account factors such as the width, depth, topography and geological conditions of the water surface of the reservoir, another segmented fixed hole leakage gate can be dismantled and automatically alarmed. Backup dam for the gate. Then, according to the width across the water surface and the effective length of each baffle plate with holes to expose steel bars, the number of segments when crossing the water surface is determined, and the number of cement piers at the supporting points is determined at the same time. The construction method of cement piers is basically the same as that of bridge piers. The height of each concrete pier depends on the depth of the water where it is located. The width of the steps of the cement pier is determined by the thickness of the baffle with holes and exposed steel bars; its height can be installed with 1-3 pieces of exposed ...
