A construction method of a floor drain in a room with water in a high-rise building and a composite floor drain used therein

Abstract

The invention discloses a construction method for a floor drain in a room with water in a high-rise building and a composite floor drain used. The invention adopts a composite floor drain. The composite floor drain is composed of a lower floor drain 1, an upper floor drain 2 and a movable sleeve 3. Specifically, the construction is carried out according to the following steps: installation Lower floor drain 1 and slope finding layer 6 → waterproof and pipeline construction → filling layer construction → install movable casing 3 and lower floor drain 1 → lay face brick 11 . The invention can conveniently adjust the height between the lowering plate and the face brick through the movable sleeve, and is applicable to rooms with different depths of the lowering plate. The upper and lower floor drains are equipped with sinking tanks, which can prevent the air in the drainage system from turning up, and can also prevent the water on the facing bricks from leaking to the lower floor. The invention adopts the composite floor drain to better solve the leakage problem of the water-filled rooms of high-rise buildings.

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 ...
