AI Technical Summary

Technical Problem

Existing copper waterstops are easily damaged during the construction of concrete-faced rockfill dams, and existing protective devices can damage the dam surface structure, affect the concrete pouring on the other side of the copper waterstop, and are inconvenient to disassemble and install.

Method used

A copper waterstop protection device for rockfill dams was designed, including a mounting base and a protective cover. The mounting base is supported on the dam surface, and the protective cover is placed above the copper waterstop. The protective cover is connected by a plug rod and a socket. A counterweight and a connecting rod provide stability. The fixing point is located at the top of the dam surface, so as not to affect the construction on the other side of the copper waterstop.

Benefits of technology

The protective device does not damage the dam surface structure, facilitates concrete construction on the other side of the copper waterstop, and is easy to install and remove, avoiding direct contact damage to the copper waterstop.
