What should be paid attention to when using the combi wallCombi-walls are piling walls that are comprised of high modulus structural components inter spaced by lighter sheet piles. The high modulus components known as king piles can be tubular, box, bearing or other types of fabricated piles. Here i

What scenarios are interlocked pipes applied toIn the process of excavating large-section tunnels, firstly, interlocked pipe must be driven into the geotechnical section to form a pipe curtain as the initial support structure. Then, earth excavation and tunnel support are carried out in the protecti

what is interlocked pipesInterlocked pipe, a composite concrete pipe in which both the inner and outer surfaces are plastic. The interlocked pipe may be formed of any diameter by forming the inner and outer plastic surfaces from helically wrapped interlocking plastic strips to form the diameters des

What are the types of interlocked pipesThe interlocked pipe means pipe with a certain clutch or interlock to connect with each other, or connect with sheet piles to form a combined wall.For the interlock, we could provide both hot-rolled SLZC9 interlocks and cold-rolled interlocks. The hot-rolled in

What are the characteristics of combi wallsCombi-walls are walls created using a mix of steel pipe and sheet pile. They can be temporary or permanent, and they’re a good alternative to traditional retaining wall structures such as secants or sheet pile walls. Here is the content list:l Notes on the

The history of interlocked pipesToday, with the advancement of industry and technology, interlocked pipes can meet all these requirements. Due to its high strength and shock resistance, interlocked pipe can be used as a highly reliable foundation. Therefore, they are widely used as foundation piles

How to use interlocked pipesThe 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. Here is the content list:l What is the main design of the interlocked pi

How to maintain interlocked pipesInterlocked pipe is used to create a strong foundation for large, heavy structures such as buildings, bridges and roads. The interlocked pipes are made of steel pipe that’s driven or drilled deep into the ground in order to help distribute the weight of a structure d

how to maintain combi wallsFor quay-wall construction of ports, in tunnels or river crossings combi-walls are used as retaining walls. The system consists of tubular piles equipped with connectors (named also interlocks, locking bars or clutches) compatible with U or Z type infill sheet piles. combi

The main concern for people using the cold-formed sheet pile is its waterproof function at the interlock.
However, whatever it is cold-formed sheet pile or hot-rolled sheet pile, both of them could not be 100% waterproof. So it is quite necessary to use the sealant at the interlock if the project has a very high waterproof requirement.
