With the continuous development of urbanization, infrastructure construction is accelerating, and the proportion of cement pipeline projects in infrastructure construction is also increasing. In the current construction, because of the widespread use of cement pipes, it is closely related to people's lives. Prevention of common problems with cement pipes is a top priority. Today, Xiaoxin Xiaobian will teach you how to prevent leakage and blockage of cement pipes.
Cement pipeline engineering is a concealed project. In order to prevent the formation of pipeline blockage during the intersecting construction, before the pipeline installation, you should carefully dredge the lumen, remove debris, and properly use drainage fittings in accordance with standard rules. When installing pipelines, you should ensure the slope In addition to the planning requirements and standard rules and the use of cement mortar to seal the drainage pipe mouth, various technical methods must be adopted to prevent pipeline blockage: due to the needs of the building structure, when a B-shaped pipe is installed on the riser pipe, according to the standard It is required that a viewing port should be provided at the upper part of the B-shaped tube for easy maintenance.
When the cement pipeline is installed, the buried discharge pipe and the riser are temporarily not connected. Check the socket end of the riser to support it with a supporting base or other methods, and seal the riser through the second floor floor hole in time. After the tube was reliable, the temporary support was removed. After the civil decoration is completely completed, before the water pipe is set up with a branch pipe device, do irrigation experiments on the ground floor and the pipes above the second floor. During the drainage pipeline construction, after the drainage pipeline filled with water capsule filling inspection is qualified, if the drainage flow rate is found to be slow during the drainage process, it is clear that there is a blockage in the horizontal branch pipe section, the blocked part of the horizontal branch pipe should be identified, and the waste Clean up debris. In order to ensure that floor drains and roof nozzles are protected from yellow sand, stones, waste, etc. from falling into the drainage pipes, all floor drains and rainwater nozzles of vent pipes protruding from the roof should be closed with cement mortar in a timely manner, and frequently check whether the closed nozzles have been Civil workers dismantled.
When the sanitary appliances are in place, first remove the temporary closing parts of the drainage pipe openings, check whether there is any debris in the pipe, and clean up the pipe openings. Carefully check that the rows of sanitary appliances are not blocked, and then place the sanitary appliances in place. . When building a urinal in civil construction, the sewage pipe opening should be blocked with a wooden plug to prevent the mortar and waste from falling into the sewage pipe when the civil mortar is applied to the cement mortar or the decorative tile surface.After the completion of the water permeability test, the hood drainage is installed. Tie and protect it. In the terrazzo ground construction, the temporary drainage method should be confirmed to prevent the drainage pipeline from being used as its drainage channel. Drain plugs, floor drains, and other water storage elbow plugs will not be blocked during the intersecting construction, and the device should be flushed before the water flow experiment.
