What Are The Applications Of Steel Sheet Piles?

There is a good steel sheet piles for sale in China, whether it is hot-rolled AZ type steel sheet piles or cold-formed U-type steel sheet piles, they are all sought after in the market. Here are seven applications of steel sheet piles you might use in your construction projects!

1. Temporary shallow excavation foundation work

Temporary shallow excavation foundation work and road projects. Usually, No. 3 and No. 4 sheet piles with locks can keep the excavation work dry and the environment unaffected. The length of steel sheet piles varies from 6 meters to 15 meters, and excavators are often used to drive vibratory hammers. Whenever you see an excavator working nearby, you are bound to see sheet piles in use!

2. Waterproof cofferdam in the river

Waterproof cofferdam in the river. Usually, the wider No. 6 pile is used. The interlocking sheet piles are between 15 and 24 meters in length and are driven by a hydraulic vibratory hammer Model 416L. For more complex soils that may contain gravel, choose a medium-sized hammer such as the 815C. The cofferdam provides a dry dock for the construction of concrete foundations. After the pylons are built, the steel sheet piles will be taken out and reused.

3. Avoid mud and bulkheads

Deep foundations with mud and diaphragm walls need to be avoided. Sometimes steel sheet piles are combined with casing piles for greater lateral load bearing capacity. These applications require AZ type sheet piles in lengths of 24-36m. For excavation depths up to 20 meters, these wide sheet piles are economical and provide great lateral load bearing capacity. The mid-size 815C or larger 1412C are often chosen for these environmentally friendly construction projects.

4. AZ type steel sheet piles harbor wall

AZ-type steel sheet piles are also commonly used as permanent harbor walls. These harsh working conditions require the selection of high-grade steels that are rust-resistant. Special coatings can be given to steel sheet piles which are most subject to seawater and wind corrosion. Due to the relatively large length and weight of the steel sheet piles for this type of wall, it is recommended to use a large vibratory hammer, such as 82NF or 1412C, and often an NL-type impact hammer is required to complete the last few meters of pile sinking.

5. Construction of underground urban comprehensive pipe gallery

The excavation work during the construction of the underground urban comprehensive pipe gallery is protected by the steel sheet pile wall. Resonance-free hydraulic hammers allow you to work next to existing buildings without disturbing residents with noise or damaging structures with low-frequency vibrations.

6. Permanent load support structure

AZ type steel sheet piles can also be used for permanent load supporting structures of railways, expressway overpasses, and garages. It can obtain two functions of good soil retention and good bearing capacity. The medium 815C and larger 1412C hammers are often chosen for these construction projects.

7. Concrete sheet piles

Concrete sheet piles are on the banks of rivers and waterways, and the cost of concrete sheet piles is low and eye-catching. Standard-strength concrete piles can be driven with a hydraulic vibratory hammer, and thinner concrete sheet piles are easily damaged by resonance, so a resonance-free hydraulic hammer must be used.
