Detailed introduction

Construction technology points and practices:

Measures and main points for roof roll bulging, cracking and mouth opening prevention:

Strictly control the moisture content of the base layer and the protective layer. After the base layer is dry, lay the heat preservation layer and waterproof layer. If the moisture content of the base layer and insulation layer is greater than the requirements of the specification, drainage grooves and exhaust holes must be provided.

Make an arc at the joint between the daughter wall and the roof. The radius R of the arc should not be less than 150㎜ to ensure that the base layer of the coil is firmly bonded and no additional layer is missed.

The construction shall be carried out according to the requirements of the specification, and the length of the coils shall be strictly controlled.

Leakage prevention measures and construction points of the surrounding wall of the pipeline out of the roof:

① The hole repairing work of the roof pipe should be completed before the roof waterproof layer, including the hole repair of the pipe. And a special person is responsible, and no plumber can make up holes to ensure repair quality.

The four-wall loose pumice stone is reserved for chiseling, and the rubbish is removed. The bottom mold must be firmly supported to ensure that the leakage slurry is not dropped.

② After wetting with water in advance, pour 20㎜1: 2 cement slurry to grout, and top up with C20 and micro-expansion agent fine stone concrete, and require compacting.

③ Use waterproof grease to caulk the surface the next day, and then use 1: 2 cement mortar to level the roof, and make a hoe around the pipe. It is better to fill in sealing material between the hoe and pipe Waterproof treatment.
