Second, the secondary drain, if there is a direct sewer pipe, there is no need to use the drain, on the sewer pipe around the sealing glass glue can be. The purpose of the drain is to facilitate maintenance and easy disassembly.

Toilet sink refers to the discharge of toilet sewage or floating debris. In the past, the non-standard practice was to pour decoration garbage directly into it, and pave the floor tiles with cement and sand. Later, considering the load-bearing and water accumulation problems, lightweight ceramsite backfill was used, and the gap between the ceramsite grains was convenient for water to seep into the ground and drain out (overhead meaning). >>>More
Can not be copied, lightweight bricks.
After the slag absorbs water, the strength will be reduced. >>>More
Toilet sink overhead is an improved practice to overcome the drawbacks of backfilling, used for large bathrooms and kitchens that need to be cleaned and maintained frequently, and it is still subject to technological progress and cost reduction in the family. >>>More
Disadvantages of backfill method: 1. The natural settlement of the material causes cracks in the surface waterproofing, and the water leakage soaks the backfill material, which increases the load, resulting in greater settlement, and even cracking of the pipeline, and finally the waterproofing of the lower layer fails early and leaks; 2. The leakage can only be found after the leakage has occurred and then make up for it. >>>More
Do two times of waterproof coating, these two times of waterproofing must be done together with the wall, and the height of the wall should be more than 40 cm higher than the upper edge of the caisson. Ensure that the seepage water in the upper layer will not expand to the periphery, and can only be discharged to the floor drain. Red brick or concrete is used as a partition overhead, and the caisson is divided into several 400*400 lattices. >>>More
