It should be known that no matter whether it is a highway or an underground tunnel, a tunnel, or various sewage plants, water purification plants, parks, stadiums, etc., drainage pipes are used. In addition, different types of drainage pipes of different types and specifications are used for the installation of underground drainage pipes in different land preparation projects. Furthermore, so many businesses are facing the problem of sewage pipe installation, then the following is a brief introduction to the precautions for sewage pipe installation.

 

1. The surface of the socket, socket and aprons must be cleaned, and all adhesives, such as sand, soil and loose coatings, and attachments that may pollute the water quality and break the aprons, etc., are cleaned and scooped off.

 

2. When wearing the rubber ring, you should wear gloves. Bend the rubber ring into a heart shape and put it into the socket groove to ensure that all parts are not warped or twisted, and check whether the fixing of the rubber ring is correct.

 

3. Clean the outer surface of the socket, whether the socket end is rounded and has a certain taper, so that it is easy to fit into the socket. Lubricate the inner surface of the rubber ring of the socket and the outer surface of the socket. The lubricant can be soapy water, detergent, etc.

 

4. Align the socket with the socket. Pull the hoist by hand to fit the socket into the socket. The deflection angle of each interface should be less than 2 degrees.

 

5. The minimum gap between the counterparts should not be less than 3mm. The maximum gap should not be greater than the specified (maximum gap 5 ~ 8mm), and consider that the interface material will not "jump into the well". When checking the interface, insert the probe into the gap of the bearing interface to determine the position of the aprons.

 

6. The aprons should be stored separately, to prevent heavy pressure during storage and to be separated from oily objects, away from heat sources. During construction on site, cover with canvas to prevent exposure.

 

7. When installing, use the side line or the center vertical line to control the center of the pipeline. The height of the cushion must be accurate to control the height of the safety pipe and check with a level. When installing the pipeline, use 4 wedge-shaped concrete cushions placed on both sides of the pipeline at a 90-degree angle, and its longitudinal distance from the pipe end is 1/5 of the distance. There are full-time personnel to direct the operation; do it gently to avoid damage.

 

The above are the precautions during the technical installation. The personal safety of the construction personnel in the installation process of the steel pipe installation company needs more attention. The sewage pipe network project has deep trenches and long lines, and there are many hidden safety hazards. A little carelessness can easily cause casualties for operators and other personnel. Whether the safety management work is in place will directly affect the construction progress, quality and investment. Therefore, safety management is the top priority in pipeline installation and construction. The main points of the safety management work are as follows: First, the enclosure along the construction line should be done, and safety warning signs should be hung; Second, the slope should be applied according to the specifications, and those who cannot be placed on the slope must be supported; There should be sidewalks no less than 0.8m on both sides of the trench; Fourth, the upper and lower trenches should have ladders with sufficient length and sufficient strength; Fifth, strengthen slope monitoring and discover abnormal conditions such as cracks. Continue construction; Sixth, strengthen safety education and safety disclosure, and do good personal protection; Seventh, strengthen construction safety management in winter and rain to prevent accidents such as collapse of frozen soil or erosion of rainwater.
