Larssen steel sheet pile installation is crucial for both watertightness and safety, and is one of the most critical steps in construction. During installation, the following requirements must be observed:

1. Larssen steel sheet piles are installed using a crawler excavator. Before installation, the conditions of underground pipelines and structures must be carefully assessed, and the exact centerline of the support piles must be carefully laid out.

2. Before driving, inspect each steel sheet pile individually. Remove any severely rusted or deformed sheet piles at the joints. Repairs to ensure proper alignment are in place before use. Sheets that remain unqualified after repair are prohibited.

3. Before driving, grease the inside of the steel sheet pile's locking groove to facilitate insertion and removal.

4. During the installation process, measure and monitor the inclination of each sheet pile. If the inclination is excessive and cannot be corrected by pulling the piles into line, the piles must be pulled out and re-driven.

5. Ensure the steel sheet piles are tightly packed and at least 2 meters deep into the ground after excavation to ensure smooth closing. In particular, check that corner steel sheet piles are used at the four corners of the well site. If these are not available, seal the gaps with auxiliary methods such as old tires or rags to prevent leakage and the carryover of sediment, which could cause ground collapse.

6. During foundation trench excavation, monitor the steel sheet piles at all times. If any significant tilting or heaving is observed, immediately add symmetrical supports to the tilted or heaved areas.
