Generally, before the cement drainage pipe is tested, the surroundings of the drainage pipe mouth will be cleaned and cleaned, and the temporary pipe will be blocked. After admitting that there is no debris in the pipe, find the center line of the cement drainage pipe mouth, and make a symbol on the wall. The first steps in this process are:
1. For stable installation of multi-seat squatting pans, first check the consistency of the nozzle elevation and the distance from the wall to the wall. Find the level, measure the height of the pissing pan, calculate the wall space, and then start the installation.
2. According to the interval between the fixing hole of the high water tank and the water supply hole, find the height of the fixing bolt, draw a cross line on the wall, clean the debris in the hole, insert the dovetail bolt into the hole, and perform the cement Twist firmly. Install the high water tank on the fixing bolts, and screw the rubber pads and nuts to a moderate tightness.
3. After the cement drainage pipe is basically formed, if it is not professional, the reinforced mesh is often painful, which means that the protective layer of the reinforced mesh is not installed properly, and may leak and make the road surface sink. Therefore, special attention should be paid to the installation.
