Water-seepage-preventing construction method for garage roof

Abstract

The invention discloses a water-seepage-preventing construction method for a garage roof. The water-seepage-preventing construction method comprises the following construction steps: 1, surveying andsetting out are conducted on the built garage roof, and a blind ditch layout line is determined; 2, after a surface layer of the garage roof is subjected to waterproofing treatment, a blind ditch cushion layer is laid on the surface layer of the garage roof to make the cushion layer have a certain gradient in the water collection direction according to the blind ditch layout line; 3, a blind ditchnetwork constituted by a plurality of blind ditches is formed on the blind ditch cushion layer in a bricklaying mode through solid bricks according to the blind ditch layout line, water falling holesor drainage openings are formed in the tail ends, in the water collection direction, of the blind ditches, the water falling holes communicate with a water-collecting well through pipelines, or the drainage openings communicate with a municipal drainage pipe network; and 4, concrete cover plates used for sealing the blind ditches are poured above the blind ditches, and then after earthwork backfilling is conducted on the garage roof, a terrace is formed.

Description

technical field [0001] The invention relates to the technical field of house and residential construction, in particular to a construction method for preventing water seepage on the roof of a garage. Background technique [0002] When building the floor of a real estate, it is necessary to construct drainage ditches. Generally, open ditches and water collection wells are used for drainage. However, since the open ditches are formed by backfilling earthwork or the ground is directly broken, when working on open ditches, on the one hand, It is not conducive to the tamping of the formed backfill. On the other hand, when the ground is broken, the ground formed by the backfill will be greatly disturbed, which will easily lead to poor safety protection performance. [0003] Moreover, the above-mentioned process of building drainage is carried out after the floor surface is formed, so that it is easy to cause the delay of the entire construction process, and the construction operat...

[0002] When building the floor of a real estate, it is necessary to construct drainage ditches. Generally, open ditches and water collection wells are used for drainage. However, since the open ditches are formed by backfilling earthwork or the ground is directly broken, when working on open ditches, on the one hand, It is not conducive to the compaction of the backfill soil. On the other hand, when the ground is broken, it will greatly disturb the ground formed by the backfill soil, which will easily lead to poor safety protection performance.

[0003] Moreover, the above-mentioned process of building drainage is carried out after the floor surface is formed, so that it is easy to cause the delay of the entire construction process, and the construction operation will cause a large amount of labor. Like this, not only the cost is high, but also the installation of the open ditch cover The operation is cumbersome, and at the same time, due to the limitation of the location of the ditch, it is not conducive to the overall layout of the open ditch drainage, which greatly increases the cost of the construction operation
