Building water supply and drainage pipeline convenient to install and use method

Abstract

The invention discloses a building water supply and drainage pipeline convenient to install and a use method. The building water supply and drainage pipeline comprises a first mounting pipeline and a second mounting pipeline, a mounting groove is formed in the outer side of the bottom end of the first mounting pipeline, and a plurality of elastic rods are arranged on the inner side wall of the top end of the second mounting pipeline. The top end of the second mounting pipeline sleeves the outer side of the bottom end of the first mounting pipeline, and the bottom ends of elastic rods are embedded in the mounting groove. The use method of the building water supply and drainage pipeline comprises the following steps that S1, first expansion bolt holes are drilled; S2, the first mounting pipeline is fixed through first expansion bolts; S3, the top end of the second mounting pipeline sleeves the outer side of the bottom end of the first mounting pipeline; S4, the bottom ends of the elastic rods are inserted into the mounting groove; S5, a reinforcing sleeve is rotated; S6, second expansion bolt holes are drilled; S7, the second mounting pipeline is fixed through second expansion bolts; and S8, sealant is smeared at the upper end and the lower end of the reinforcing sleeve, and mounting operation of the building water supply and drainage pipeline is completed.

Description

technical field [0001] The invention relates to the field of building water supply and drainage, in particular to a conveniently installed building water supply and drainage pipe and a use method. Background technique [0002] At present, drainage pipes refer to the system of pipes and channels for collecting and discharging sewage, waste water and rainwater and their ancillary facilities, including main pipes, branch pipes and pipes leading to treatment plants, no matter they are built on streets or anywhere else, as long as they are The pipes that play the role of drainage shall be counted as drainage pipes. [0003] In buildings, drainage pipes are mainly used for roof drainage, which are generally installed on the wall surface of buildings. With the different heights of buildings, multiple pipes can be used for splicing, so as to realize the drainage work of buildings; When connecting the pipes, the end thread is generally used for connection. However, due to the high b...

Problems solved by technology

[0003] In buildings, drainage pipes are mainly used for roof drainage, which are generally installed on the wall surface of buildings. With the different heights of buildings, multiple pipes can be used for splicing, so as to realize the drainage work of buildings; When connecting the pipes, the end thread is generally used for connection. However, due to the high building, it is not easy to realize the connection operation of the drainage pipe in the middle of the outside of the building; in addition, sometimes the installation position of the drainage pipe is located at the corner of the building. Rotate the installation of the drainage pipe, therefore, it is necessary to study a drainage pipe that is easy to install to solve the above problems
