How to Use Spiral Piles and an Overview of the Processing Technology

How to Use Helical Piles

Ensure a high mud level in the borehole to enhance the pressure on the hole walls.

In the soft clay and loose areas with high groundwater levels locally, it is crucial to ensure the quality of the mud to meet construction specifications and provide adequate wall protection. To maintain the mud level within the borehole, a dike is constructed at the borehole mouth to connect with the mud inside. When removing the drilling tools, mud from the dike is replenished into the borehole, ensuring the mud level remains above the groundwater level. The higher the mud level, the greater the pressure on the borehole walls, thus increasing stability.

2. Regulate the drilling speed to prevent the occurrence of mud cake on drill bits.

When working on soft-plastic soil, the pile is designed to prevent penetration into the strata. During operation, it records the depth of each hole and drills from that point. It controls the drilling speed to minimize excessive disturbance to the layer.

3. Controlling the Length of Production

During the soft plastic soil stage, the rate of footage advancement is slower than usual to prevent or reduce the resistance caused by the piston effect during drilling retrieval.

Ensure the drill bit surface is smooth to prevent or reduce sticking in soft plastic soil. During each lift, the drill bit's circumference often adheres to some sticky soil. It is essential to clean it promptly to reduce adhesion between the drill bit and the surrounding sticky soil, preventing sticking.

5. Reduce the link gap between drill bits and drill rods.

Regularly inspect the connection of the drill bit and drill rod for wear, and address it promptly to reduce the link gap.

Over-sizing is a common issue in rotary drilling on soft-plastic and loose soils, which necessitates a proactive approach. This requires the drilling machine managers and operators to recognize the hazards of over-sizing, and to formulate preventive measures in advance for all strata to avoid significant losses during construction.

Secondly, Introduction to the Processing Technology of Photovoltaic Spiral Steel Piles

Photovoltaic spiral steel piles are widely applicable across various industries due to their high load-bearing capacity, stability, anti-settlement, and tensile resistance, which have garnered favor within and outside the industry. Let's take a look at the processing technology of photovoltaic spiral steel piles.

The processing level of photovoltaic helical steel piles directly determines the service life of metal piles. Factors such as the quality of the welded pipes used, the welding quality standards, the presence of sand holes or cold joints, the width of the weld, all impact the future service life and subsequent processing quality of the photovoltaic helical steel piles. Pickling is an essential anti-corrosion foundation process, and the quality of hot-dipping, such as the duration of hot-dipping and the effectiveness of surface treatment, also affects the quality of the anti-corrosion treatment for the photovoltaic helical steel piles.

Under normal circumstances, photovoltaic helical steel piles can be used for 40-80 years. The environmental conditions during use and the methods of operation also affect the lifespan of photovoltaic helical steel piles, such as the acidity or alkalinity of the soil, the appropriateness of the operation process, and improper use can lead to the damage of the metal pile surface, the destruction of the metal protective layer, and accelerated corrosion of the metal piles, reducing their lifespan.

Photovoltaic spiral steel piles typically undergo processes such as cutting, shaping, welding, acid washing, and hot galvanizing to produce qualified products. Acid washing and hot galvanizing are crucial anti-corrosion treatments, directly impacting the lifespan of photovoltaic spiral steel piles.
