Description

TECHNICAL FIELD

[0001] The utility model belongs to construction equipment technical field, concretely relates to a fixed point piling device for engineering construction. BACKGROUND

[0002] The fixed point piling device for engineering construction (also known as directional piling device or pile foundation piling device) is an equipment for accurately positioning and driving into pile foundation in the construction process. The pile foundation is usually used to support the foundation of buildings or other structures, especially in the geological conditions of uneven or soft soil. The fixed point piling device plays a key role in ensuring the verticality, stability and depth accuracy of the pile foundation. With the progress of technology, the accuracy and automation level of the fixed point piling device are becoming higher and higher, which can meet the construction needs under different complex conditions.

[0003] In the prior art, the fixed point piling device drives the pile into the ground to the predetermined depth by hydraulic, mechanical or electric driving pile hammer or impact pile machine. However, since the pile is not limited or supported and fixed, when the piling device strikes the top end of the pile to drive it into the ground to the predetermined depth, the pile is prone to tilting displacement, which causes the pile to be unable to be vertically driven into the ground. Moreover, the deviation of the pile position will cause the piling point to deviate. In order to ensure the verticality of the fixed point piling, the top end of the pile is generally limited, so that the hydraulic device can exert a vertical downward force on the pile, thereby enabling the pile to be vertically driven into the ground. However, due to the long length of the pile and the lack of fixation at the bottom end, combined with different geological environments, the pile will be subjected to resistance, causing the pile to be tilted and driven into the ground, thereby affecting the stability of the foundation.
