Description

Pre-buried line box of tensile crack

Technical Field

The utility model relates to a water and electricity engineering technical field especially relates to a pre-buried line box of tensile crack.

Background

At the current pre-embedding stage of the hydroelectric engineering, as shown in fig. 1, the interface end 2 of the pre-embedded line box on the board surface is perpendicular to the connection surface of the box body main body 1. After the pre-buried pipe distribution is finished, and then the pipe is bound and fixed by iron wires, an included angle which is obviously smaller than 90 degrees is usually formed between the pipe and the box body. At the moment, the interface end can generate tensile stress at the upper end of the joint of the box body main body. When the pressure of the outside is applied, the line pipe is deformed, so that the tensile stress at the upper end of the joint is increased. When this tensile stress is greater than the tensile yield strength of the upper end of the joint, cracking occurs. Particularly, in freezing weather, the wire box shrinks when being cooled, the internal stress is increased, and the box body becomes brittle, so that the breakage is easier to occur.
