Problems solved by technology
[0002] At present, in the field of building water supply and drainage, the installation of drainage risers must consider the influence of material expansion and deformation. Usually, the method of installing expansion joints on the drainage riser is adopted; in the actual construction process, due to improper reservation of expansion or installation, Water seepage of expansion joints often occurs, which leads to problems in the quality of pipeline installation, which in turn affects the lives of residents; in addition, the pipeline installation method of the prior art must be carried out step by step according to the construction sequence, the construction speed is slow, the efficiency is low, and the maintenance and replacement of the single-layer riser Difficult, prone to leakage

Embodiment Construction
[0012] The technical solution of the present invention will be described in further detail below with reference to the drawings and specific embodiments.
[0013] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown in the figure, there is a telescopic piece specially used for the connection of building drainage standpipe. The telescopic piece includes a water inlet bucket 1, a telescopic plug 2, a supplementary sleeve 3 and a sealing collar 4. The upper part of the water inlet bucket 1 is provided with a pipe socket 5 , the lower part of the water inlet bucket 1 is provided with a pipe intubation pipe 6, the pipe intubation pipe 6 is connected to the pipe socket pipe 5, the telescopic socket 2 is provided at the top of the telescopic plug 2, and the connecting pipe 2 is provided at the bottom of the telescopic plug 2. Pipeline insertion pipe 8, the connecting pipe insertion pipe 8 communicates with the telescopic socket pipe 7, the supplementary sleeve 3 is a cyl...

The invention provides a special telescopic piece for building drainage standpipe connection, which includes a water inlet bucket, a telescopic plug, a patch sleeve and a sealing collar, the upper part of the water inlet bucket is provided with a pipe socket, and the lower part of the water inlet bucket is provided with a pipeline Intubation, the pipe intubation is connected to the pipe socket, the telescopic socket is provided on the upper part of the telescopic plug, and the connecting pipe intubation is arranged on the lower part of the telescopic plug, and the connecting pipe intubation is connected to the telescopic socket pipe, the supplementary sleeve is a cylinder, wherein the pipeline insertion tube is inserted into the telescopic socket insertion tube, the supplementary sleeve is sleeved at the lower part of the connecting pipeline insertion tube, and the sealing ferrule is sleeved at the The lower end of the supplementary sleeve is described; the supplementary sleeve is a round tube body, and a shrinkage opening is opened on the side of the supplementary sleeve along the axial direction. The telescopic part overcomes the problem that the current telescopic joint connection is easy to leak, and at the same time changes the technical problem that the current riser connection must be carried out sequentially, which causes the installation speed to be slow and cannot be replaced.
