Cement drainage pipes are everywhere around us, and it has provided us with a lot of help. We want to know why this is. Let me introduce the regulations for the cement drainage pipe interface tape, please read carefully.
1. The outer wall of the pipe mouth should be chiseled and washed before wiping. When the pipe diameter is less than or equal to 400MM, the cement mortar wipe band can be wiped at one time; when the pipe diameter is greater than 400MM, it should be wiped into two layers;
2. The end of the wire mesh should be inserted into the concrete when the concrete socket is poured. Before the concrete is initially set, the wire mesh cement mortar tape should be layered and layered; the wire mesh should be placed below the pipe before it is in place. The steel wire mesh should be wiped and solid, and the steel wire mesh should not be exposed;
3. Immediately after wiping the tape, cover it with flat soft data and water it for maintenance after 3 ~ 4H;
4. The thickness of the cement drainage pipe must not be less than the thickness of the pipe wall, and the width should be 80 ~ 100MM.
