In general construction projects, seasonal climate, hydrology, concrete, and site factors can hinder the construction process to a certain extent. These factors affect the efficiency of using hydraulic pile drivers.

Let's analyze how these factors impact the efficiency of hydraulic pile drivers:

Firstly, as described in the "Building Code" and "Deep Foundation Pit Construction" guidelines regarding the selection and specification of pile drivers, different geological conditions are closely related to drilling rig efficiency, construction difficulty, construction plans, mechanical wear, and material consumption. Pile types include cast-in-place piles and prefabricated piles, with prefabricated piles including steel pipe piles and concrete piles. The choice of pile type is mainly determined by geological conditions, building height, noise and pollution restrictions in the construction area, project timeline requirements, quality requirements, economic considerations, and the preferences of the design institute. When selecting piles, the type of pile driver can generally be determined. Recommendations are provided in the guidelines, and the pile driving team’s experience, as well as consultations with rental companies and pile driver manufacturers' customer service, can be beneficial.

From the perspective of the equipment itself, the rationality of the pile driver selection impacts construction efficiency. Additionally, the temperature rise of hydraulic oil affects the operating speed of the guardrail pile driver. Specifically, when sediment blocks the hydraulic oil cooler, the oil temperature can exceed 70 degrees Celsius. At high temperatures, hydraulic oil loses its anti-wear and lubrication functions. Prolonged high temperatures increase mechanical wear and vibration. Furthermore, bubbles increase the contact area between oil and air, accelerating oil oxidation and significantly slowing down the operation speed.
