Analysis of the causes of sinking of drainage pipes

Underground pipelines are an important infrastructure to protect the city's production date. If there are some accidents, it will cause inconvenience to people's lives. Therefore, the construction quality of the pipeline needs to be strictly controlled. In addition, the needs of drainage pipes are regularly inspected and protected, problems are found and solved in a timely manner, and incidents are prevented from developing in a serious situation. This can not only ensure the normal operation of the pipeline, but also save the cost of maintenance and repair of the drainage pipeline.

What are the detailed reasons for the drainage pipe sinking?

The drain professional explained the following analysis with us:

Drainage pipeline construction quality and not in place

During the construction of the drainage pipeline, if a comprehensive quality inspection is not done, or if the item of closed water test is omitted, the leakage may appear during the delivery pipeline operation.

The main reason for the formation of leakage is due to the inadequate contact between the tube wiper interface and the inspection well. Leakage for a long time is not prevented, which will cause the loss of formation soil or the formation of quicksand, which will cause the sinking and damage of the pipeline, and the ground will be broken in severe conditions.

Mishandled at interface

Inappropriate treatment of data, form, structure and installation orientation at the interface will cause leakage of the pipeline. The rigid interface lacks rigidity, the semi-rigid interface becomes rigid again, and the rigid interface is added to the flexible interface, so that the flexible characteristics cannot be brought into play. These unreasonable treatment methods will all become factors for the pipeline to sink.

Lack of ground geological considerations

The drainage pipe is a linear structure, and the geological conditions along the length of the pipe are relatively chaotic. There is no consideration of the deformation of the foundation. During the implementation of the drainage pipeline, the foundation may be more just a check of the bearing capacity, and the issues of foundation expansion joints and settlement joints have not been considered in detail. This will cause the foundation to deform under certain circumstances, for example, the groundwater will rise, making the soil more viscous and deforming, causing the pipeline to sink.

Thinking of Drainage Pipeline Project Operation

Necessary check before using the drainage pipe

A thorough inspection is required before the drainage pipe enters the site. When cracks and scale problems are found, they will not be used. In terms of impermeability, the nozzle can be modified with appropriate water glass to enhance its impermeability.

Selection and cushion treatment of pipes

The selection and laying requirements of pipelines are reasonably arranged according to the characteristics of the foundation. When the foundation is rock, it is not suitable to lay the pipeline directly on it. This may cause uneven pressure on the pipeline and cause damage to the pipeline. At this time, the correct method is to choose a sand cushion layer of 15-500px. On some foundations where the soil is not too sticky, gravel cushion is generally used.

Strengthen non-excavation correction of drainage pipes

From the perspective of urban development, when the drainage pipeline is damaged, the non-excavation modification can minimize the impact of the project on the daily production of urban residents.

Underground pipelines are an important infrastructure to protect the city's production date. If there are some accidents, it will cause inconvenience to people's lives. Therefore, the construction quality of the pipeline needs to be strictly controlled.

In addition, the needs of drainage pipes are regularly inspected and protected, problems are found and solved in a timely manner, and incidents are prevented from developing in a serious situation. This can not only ensure the normal operation of the pipeline, but also save the cost of maintenance and repair of the drainage pipeline.
