How to use interlocked pipes?


The interlocked pipe is a non-watertight pipe for use in stormwater applications. The interlocked pipe itself is used for centering the pipe during laying operations, thus making the process easier.

What is the main design of the interlocked pipes?

Although the interlocked pipe is primarily designed for use in a non-watertight pipe-line, rubber collars can be supplied to facilitate a measure of watertightness. These can be used for instances where ingress of groundwater, etc. must be avoided, and the more expensive rubber ring interlocked pipe is not necessary.

The interlocked pipes are manufactured in 2,44m and 1,22m, but can be manufactured in special lengths to customer specification.The standard strength classes for these interlocked pipes are 50D, 75D and 100D. Special intermediate strengths or heavier loading requirements can be designed and manufactured. These are subject to various material constraints, but will be evaluated by our engineers on an ad hoc basis.

As a pioneer wall of global cold-formed sheet pile industry and joint piling leading company, Jiangsu Shunli Steel Pipe Group is committed to the vast steel industry to make the sheet interlocked pipe industry superior!

How to handle and install interlocked pipes?

When handling any concrete products, it is important to remember that, as concrete is a heavy and somewhat brittle material, bumps or shock loads of any description are liable to damage the product. This applies particularly to sharp edges.


When offloading the products on site, the equipment must not damage the products. Larger diameter interlocked pipes have a lifting hole in the barrel, which can be used to handle the product. A sling with lifting eye and spreader bar must be used in this application. Smaller diameter interlocked pipes have no such lifting-hole, and a 150mm sling passing around the center of gravity of the interlocked pipe must be used.


What are the precautions for using interlocked pipes?

During the installation, the trench or excavation must be prepared to the Site Engineers specification. Once the bedding is in place it is ready for the interlocked pipe.The interlocked pipes are lowered into place using the same handling technique as before. Once the interlocked pipes are lined up, they are put in place. At times it may be necessary to pull the interlocked pipe joint into position to fit into the already laid pipe. This can either be done by hand, or by means of a turfor system, which pulls the pipes together.


If required, the interlocked pipes must be sealed from water ingress by means of a rubber collar or bidum strip. Once this is applied, the next pipe can be lowered into position.Backfilling of the interlocked pipe to the engineer’s specification is of utmost importance, as the pipe strength is designed to suit the installed condition. Care must be taken to compact underneath the interlocked pipe curvature to ensure a good foundation is in place.
