Hydraulic supporting dam

Abstract

The invention relates to a hydraulic supporting dam, and belongs to the technical field of hydraulic supporting dam structures. The hydraulic supporting dam comprises a water blocking shield plate (1) which is anchored to a foundation bottom plate (6). The hydraulic supporting dam is characterized in that a lifting and automatic locking device is arranged on the foundation bottom plate (6), and the height of the water blocking shield plate (1) can be continuously adjusted by a linear supporting device through the lifting and automatic locking device. The hydraulic supporting dam is reasonable in structure and design and safe and reliable to use, continuous control over the height of the dam is achieved through the lifting and automatic locking device, the supporting strength of the whole hydraulic supporting dam is increased through a deltoid plate type supporting structure, and the service life of the whole hydraulic supporting dam is prolonged through the deltoid plate type supporting structure. The height of the shield plate is adjusted through clamping grooves in the foundation bottom plate, and the hydraulic supporting dam is convenient to operate, safe and reliable.

Description

[0001] technical field [0002] The invention relates to a hydraulic support dam, which belongs to the technical field of hydraulic support dam structures. Background technique [0003] At present, rubber dams have been questioned due to their own operational safety and stability. In harsh water environments, rubber dams have a short service life. In order to further improve the safety of flood discharge and reduce the water damage of the dam itself, in some harsh water environments, hydraulic lifting dams have been used in China. However, hydraulic lifting dams have the technical defect of not being able to continuously adjust the height of the dam and the stress strength of the dam. For example, the existing movable support dams generally use rod support, and the contact area between the support rod and the water retaining shield is small, which is a point contact. The problem of rod support and point contact is that the support force is small and the structural strength ...

AI Technical Summary

Problems solved by technology

However, the hydraulic lifting dam has the technical defect that it cannot continuously adjust the height of the dam and the stress strength of the dam. For example, the existing movable support dam generally adopts rod support, and the contact area between the support rod and the water retaining shield is small, which is a point contact.

The problem of rod support and point contact is that the support force is small and the structural strength is low. Stones, wooden piles, etc. in the river will impact the support points of the gate and dam, and the support rods are prone to damage.
