Application Of Steel Sheet Piles in Construction Projects

With the development of the times, the speed of infrastructure construction has also become a symbol of our national strength. Both hot-rolled AZ type and cold-bent U type are popular in the market. The following is a brief explanation of the application of steel sheet piles in construction projects.

1. Temporary shallow excavation foundation operation 

It 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 ranges from 6 meters to 15 meters, and excavators are often used to install vibrating hammers. Whenever you see an excavator working nearby, you will see steel sheet piles being used!

2. Waterproof cofferdams in rivers

Usually use wider No. 6 piles. The length of the lock mouth is between 15 and 24 meters, and it is driven by a 416L hydraulic vibrating hammer. For more complex soils that may contain gravel, a medium-sized hammer such as 815C can be selected. The cofferdam can provide a dry dock for the construction of concrete foundations. After the bridge tower is built, it will be taken out and reused. 

3. Deep foundations where mud and watertight walls need to be avoided

Sometimes it is used in conjunction with casing piles to obtain greater lateral bearing capacity. These applications require AZ sheet piles in lengths of 24-36 meters. For excavation depths up to 20 meters, these wide sheet piles are economical and can provide great lateral bearing capacity. The medium-sized 815C or the larger 1412C are often selected to complete these environmentally friendly construction projects.

4. AZ steel sheet pile harbor wall

It is also often used as a harbor wall. These harsh working conditions require the selection of high-grade steel that is rust-proof. Special coatings can be applied to sheet piles that are more corroded by seawater and wind. Due to the large length and weight of this type of wall, it is recommended to use a large vibrating hammer, such as 82NF or 1412C, and often an NL-type impact hammer is required to complete the pile sinking. 

5. Construction of underground urban integrated pipe corridors

The excavation work when constructing underground urban integrated pipe corridors is protected by steel sheet pile walls. The resonance-free hydraulic hammer allows you to construct next to existing buildings without disturbing people with noise or damaging buildings with low-frequency vibrations.

6. Concrete sheet piles

On the banks of rivers and waterways, concrete sheet piles are low-cost and pleasing to the eye. Standard-strength concrete piles can be driven with a hydraulic vibratory hammer, but thinner concrete sheet piles are easily damaged by resonance and must be driven with a resonance-free hydraulic hammer.
