A construction structure and construction method for building an empty box structure of a ship lock

Abstract

The invention relates to a construction structure and a construction method for building an empty box structure of a ship lock. The construction structure and the method not only greatly reduce the cost of erecting the bracket formwork in the empty box structure, but also improve the construction efficiency, and the prefabricated concrete formwork is used as the main structure for pouring Part of it, eliminating most of the demolition workload and material waste, saving construction costs. In addition, the side wall formwork and the pre-embedded steel bars adopt a dislocation connection structure, so that the stress of the main reinforcement and the pre-embedded steel bars in the side wall formwork is dispersed, and the stress concentration at the same height is avoided, causing the main structure of the concrete to be unstable. This structure can replace the role of the traditional formwork, and also It can be combined with the pouring main body to form a permanent structure, and the formwork is used as a part of the permanent structure, which greatly speeds up the construction progress and saves construction costs.

Description

technical field [0001] The invention belongs to the technical field of concrete pouring engineering, and relates to a construction structure and a construction method for building an empty box structure of a ship lock. Background technique [0002] At present, the common empty box structure construction generally adopts the internal mold method and the inflatable bag method. The empty box structure similar to the thousand-ton ship lock has a large size, and the inflatable bag method is not applicable. There are two main types of internal mold methods. One is to use steel pipe brackets and formwork. After the empty box structure is poured, construction personnel need to enter the empty box to remove the formwork and brackets. Therefore, the side walls of the empty box often need to be reserved. The erection and dismantling process requires a lot of labor and materials, and the reserved openings need to be sealed again later, which seriously affects the construction progress. ...

Problems solved by technology

However, when the structure is used inside the concrete, there is a gap between the improved structure and the concrete pouring body, and the connection effect with the concrete is poor, and it cannot form a part of the concrete structure
