Construction method for floor drain of room with water of high-rise building and used composite floor drain

Abstract

The invention discloses a construction method for a floor drain of a room with water of a high-rise building and a used composite floor drain. The composite floor drain adopted by the construction method consists of a lower floor drain 1, an upper floor drain 2 and a movable sleeve 3; the construction method specifically comprises the following steps: mounting the lower floor drain 1 and a sloping layer 6; performing water prevention and pipeline construction; constructing a filling layer; moveably mounting the sleeve 3 and the lower floor drain 1; paving face bricks 11. According to the construction method and the used composite floor drain, the height between a drop plate and the face bricks can be adjusted conveniently through the movable sleeve, so that the used composite floor drain can be adapted to drop plate rooms with different depths; both the upper floor drain and the lower floor drain are provided with sinking water grooves, so that the air in a drainage system can be prevented from turning upwards; the water on the face bricks can also be prevented from leaking to a drop plate layer. According to the construction method and the used composite floor drain, the problem of seepage of the room with the water of the high-rise building can be better solved by adopting the composite floor drain.

Description

technical field [0001] The invention relates to a construction method for a floor drain in a room with water in a high-rise building and a composite floor drain used, and belongs to the technical field of anti-leakage in a room with water. Background technique [0002] In the construction of high-rise buildings, the structural slabs on the floor of rooms with water such as toilets and kitchens are usually lower than those on the floors of other non-watery rooms, which is called a descending slab structure. According to the traditional construction method, when carrying out the waterproof construction of a room with water, first make a waterproof layer on the descending plate, and then lay drainage pipes on the waterproof layer, and fill the drainage pipes with light aggregate or foamed cement. Then construct the surface layer on top of the light aggregate or foamed cement; and finally carry out the construction of the slope layer and the face brick. [0003] The descending ...
