The drainage pipe through the floor slab and the concrete flanging should be tightly waterproofed and plugged with micro-expanded fine stone concrete, and the drainage pipe through the floor slab should be retained at the root of the pipeline, and the water retaining barrier should have a slope outward, and the side drainage outlet and the connecting pipe through the wall should be coated with waterproof ointment before positioning;

The side drainage pipe shall not be connected to the drainage riser flat, and the drainage riser or 45 degree miter drainage riser shall be connected after bending down 300mm first;

Balconies and terraces should be installed with drainage floor drains, and the model of floor drains meets the design requirements.

The ground paving within the range of 200 300mm around the floor drain should increase the water collection slope and form a "funnel" type; Fu Xiang.

For the above anti-leakage construction, the engineering department should inspect its process, and it should be accepted and confirmed before concealment.

The drainage pipe through the floor slab and the concrete flanging should be made of micro-expanded fine stone concrete to do strict waterproof blocking, the drainage pipe through the floor slab should be made at the root of the pipeline to do the water barrier, the water barrier should have a slope outward, and the side drainage outlet and the wall connection pipe are positioned, and the outer wall perimeter should be coated with waterproof ointment;

The side drainage pipe shall not be connected to the drainage riser flat, and the drainage riser or 45 degree miter drainage riser shall be connected after bending down 300mm first;

Balcony and terrace should be installed with drainage floor drain, the model of floor drain meets the design requirements, and the simple drainage floor drain of the same section with the drainage branch pipe can not be used;

The ground paving within the range of 200 300mm around the floor drain should increase the water collection slope and form a "funnel" type;
