Interpretation of the characteristics and installation methods of siphon drainage pipes

Siphon drainage is a drainage method for building roof drainage. It plays an important role in the drainage of rainwater in large buildings and artistic buildings, and siphon drainage pipes are used in this.

Features of Siphon Drain

1. The siphon drainage pipe is more suitable for the artistic modeling of modern buildings, and it is easy to meet the rainwater discharge of irregular roofs.

2. It has the characteristics of large displacement of single bucket and few openings on the roof, which can reduce the probability of roof water leakage, reduce roof waterproof pressure, and reduce structural load.

3. The number of siphon drainage pipes is small and the diameter is small, which meets the aesthetic requirements of modern buildings and the drainage of large landmark buildings, various large-span roofs and high-rise buildings.

4. Without affecting the function of the building and the use of space, the siphon drainage pipe can meet the rainwater discharge of modern large-scale shopping plazas, supermarkets, factories and metal roofs with various grid structures. In addition, the system safety of the siphon drainage pipe is very high.

5. The siphon drainage pipe has the advantages of efficient drainage and low noise, which can perfectly meet the acoustic requirements of modern theaters, theaters, convention centers, schools and hospitals.

Installation method of siphon drainage pipe

1. According to the requirements of the drawing, combined with the actual situation, measure the size according to the position of the reserved mouth, and draw the processing sketch.

2. Measure the pipe size according to the sketch, and cut the pipe, and the fracture must be flush.

3. Before bonding, the socket should be inserted into the test first, and it should not be fully inserted. Generally, it is 3/4 of the socket.

4. During the installation of the drainage pipe, lead wire can be temporarily suspended for pre-installation, and the coordinates, position, pipe elevation, and slope of the spout can be adjusted to meet the design requirements for bonding, and the position and height of the spline coordinate can be corrected in time.

5. Inspection openings shall be provided at the lowest and highest levels of the drainage riser, and the center of the inspection opening shall be 1.0 m from the ground.

6. After the pipeline is installed, the pipe hole should be plugged in time, and the mold should be plugged in accordance with the requirements of the specification.

Points for Attention in Siphon Drain Pipe Installation

In the installation process, the connection of stainless steel pipes and steel pipes can be welded, flanged and grooved; the connection of cast iron pipes should be clamped as much as possible. Among them, welded and flanged connections should be galvanized twice.
