Arch tooth type anti-arch water cushion pond and construction method

Abstract

The invention discloses an arch-tooth type anti-arch water cushion pond and a construction method. Permeable concrete is arranged at the bottom of the anti-arch bottom plate as a cushion layer; and a vertical drainage pipe is arranged on the anti-arch bottom plate. Inside the permeable concrete; the anti-arch bottom plate is provided with structural transverse joints according to the distance, and the structural transverse joints adopt a slotted structure. Copper waterstop, interspersed ribs arranged in the center at the transverse joints of the structure; arch teeth are arranged at the bottom of the anti-arch floor, and the anti-arch floor and arch teeth are equipped with steel bars according to the stress of the structure, and foundation anchor tendons are set at the position of the arch teeth. The invention changes the structure and stress form of the conventional anti-arch pad pond, and overcomes the easy failure of the vertical drainage pipe of the structure foundation of the conventional anti-arch pad pond, the unreasonable combined stress of the transverse joint structure, and the stress at the end of the abutment It is not conducive to making full use of the bearing capacity of the bedrock of the floor, resulting in the disadvantage that the abutment bears a large force.

Description

technical field [0001] The invention provides an arch-tooth type reverse-arch pad pond and a construction method, which belong to the technical field of water conservancy and hydropower engineering and are suitable for the design and construction of the reverse-arch pad pond. Background technique [0002] With the development of my country's water conservancy and hydropower projects, arch dams have become one of the main dam types. The terrain on both sides of high arch dam hubs is generally high mountains and deep valleys. Many high arch dams are not suitable for arranging flood discharge structures outside the dam, and can only vent large amounts through the dam body. flood. When the arch dam uses the dam body for flood discharge, since the water tongue is relatively close to the dam site and the water depth of the downstream river bed is relatively shallow, in order to avoid excessive erosion affecting the safety of the dam foundation and the stability of the bank slopes o...

Problems solved by technology

[0004] In view of the shortcomings of the vertical drainage pipe of the foundation of the conventional anti-arch pad pond structure, which is prone to failure, the joint force of the transverse joint structure is unreasonable, and the force at the end of the abutment is not conducive to making full use of the bearing capacity of the bedrock of the floor, resulting in a large force on the abutment. The purpose of the invention is to provide an arch-toothed anti-arch water cushion pond and a construction method to overcome the above problems
