No pollution, little interference to the surrounding environment, suitable for pile foundation projects in soft soil areas, urban centers or dense buildings, and expansion projects of precision factories, static pile drivers are indispensable heavy-duty in construction projects assistive devices.

When the static pile driver presses the pile, first lift the cement pile, align the pile position, place the top of the cement pile under the beam, then start the hoist to pull the wire rope, gradually tighten the wire rope, make the movable pressure beam downward, and put the whole The self-weight and counterweight load of the pile machine is pressed on the top of the cement pile by the pressure beam to achieve the purpose of pile compression. When the pile is pressed, it must be ensured that the overall direction of the cement pile is pressed down vertically. The existing pile driver only has a pressure beam that applies pressure to the pile, and There is no limit device at the bottom of the cement pile. Manual assistance is required to allow the cement pile to enter the pile vertically. Due to the excessive mass of the cement pile, manual assistance is extremely inconvenient and easily causes errors. It cannot ensure that the pile enters the pile vertically. The position of the cement pile may also be slightly inclined during the pile process. When the inclination of the cement pile is greater than 1%, the pile must be stopped to find a solution. There is no measurement of the inclination angle of the cement pile inside the existing pile driver Mechanism, it is extremely inconvenient and has large errors when manually using instruments to measure, which cannot truly reflect the inclination of the cement pile, increases the error of construction engineering, and reduces the practicability of the pile driver.
