Roller compacted concrete dam internal prefabricated corridor structure with buckle connection and implementation method

Abstract

The invention discloses a roller compacted concrete dam internal prefabricated corridor structure with buckle connection and an implementation method. The roller compacted concrete dam internal prefabricated corridor structure comprises a corridor prefabricated part, one side of the corridor prefabricated part is provided with a positive buckle, one side, away from the positive buckle, of the corridor prefabricated part is provided with a negative buckle, a connection block is fixedly connected with the negative buckle, the positive buckle is provided with a first groove, the first groove is provided with a limit block, two first fixed disks and two second fixed disks are symmetrically arranged on the limit block, and a first connecting rod and a second connecting rod are rotatably connected with the first fixed disk. The roller compacted concrete dam internal prefabricated corridor structure has the advantages that the structure is ingenious, the use is convenient, the accuracy error of artificial hoisting can be eliminated, and the irregular faulting of slab ends caused by the vibrational rolling excited vibration force during the construction process of roller compact concrete can be completely avoided, the overall beauty of the inner surface of the prefabricated corridor is greatly improved, the probability of leakage in the joint part of the prefabricated part of the corridor is greatly reduced after the reservoir is impounded, and is worthy of being popularized.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a prefabricated corridor structure in a roller compacted concrete dam using buckle connections and a realization method thereof. Background technique [0002] In order to increase the pouring speed of roller compacted concrete and shorten the construction period of the project, the corridors in the roller compacted concrete dam are mostly in the form of prefabricated parts, that is, the prefabricated parts of the corridors are prefabricated or synchronously completed outside the site, and the roller compacted concrete (corridor) Before the ascent, the prefabricated parts are hoisted to the surface of the roller compacted concrete pouring warehouse for splicing. After the splicing is completed, the dam body RCC construction will continue. [0003] Roller compacted concrete is a kind of dry hard concrete with poor cementitious material, which is...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the prefabricated corridor prefabricated parts in the prior art are affected by the manual hoisting accuracy and the exciting force of vibrating rollers. The prefabricated corridors in the roller compacted concrete dam often produce staggered platforms at the joints of the prefabricated parts, which affects the corridor. The overall beauty of the inner surface of the corridor, and in severe cases, it will also cause the leakage of the dam body at the staggered platform along the corridor joints, and a prefabricated corridor structure in the roller compacted concrete dam with buckle connection and its realization method are proposed
