Abstract

The invention discloses a drainage pipeline mounting method free of a hanging hole. The method comprises the following steps of (1) positioning a vertical drainage pipe on site; (2) determining positioning of a lower-layer vertical pipe by a five-line gradienter; (3) conducting beveling and roughening for a hole entrance; (4) painting waterproof paint and mounting a silica gel ring; and (5) plugging waterproof mortar. By means of the method, the problems that during drainage pipeline construction, structural safety is affected by hole forming (preformed holes), floor appearance and leakage areaffected by the hanging hole and the like are solved to a large extent, and the rapid, effective and safe drainage pipeline mounting method free of the hanging hole is achieved.

Description

technical field [0001] The invention relates to the technical field of building drainage, in particular to a method for installing a hanging hole-free drainage pipeline. Background technique [0002] With the improvement of people's requirements for indoor living, working and living environment, due to various design changes and continuous changes in design concepts, there are more and more demands for secondary mechanical openings in the later stage of indoor pipeline construction. The traditional secondary opening (reserved hole) form of the floor slab has a great impact on the structural safety and leakage, and the construction of the hanging hole has a great impact on the appearance of the floor slab, so the requirements for the construction process are also constantly improving. [0003] At present, almost all of the drainage pipe construction in China adopts the form of secondary hanging holes in the floor. As far as the traditional form of the secondary opening (rese...
