Description

Technical Field

[0001] The utility model relates to the technical field of pile sinking construction, in particular to a pile holding device for sinking large-diameter steel pipe piles. Background Art

[0002] Steel pipe pile driving is a key process for bridge foundation construction at sea or in waters. Steel pipe piles are used for positioning, installation and support of large-tonnage prefabricated parts such as prefabricated bridge piers and pier bodies. They have the characteristics of high construction accuracy, complex working conditions, and a large number of piles. Due to the harsh construction environment at sea or in waters, and most of them are far away from the coastline, affected by wind, waves, currents and tides, the steel pipe pile driving construction will cause certain errors or position deviations. However, the design requirements for steel pipe pile driving required for pier foundation construction are: the relative deviation of the plane is not more than 5cm, and the verticality deviation is not more than 1 / 400.

[0003] The patent specification with announcement number CN204662444U discloses a large-diameter steel pipe pile sinking fixed guide device, which includes support piles, which are distributed around the steel pipe pile sinking position, and a fixed platform is fixed on the upper part of the support piles. A three-dimensional guide frame is installed on the fixed platform, and a hydraulic pile gripper for limiting and positioning the steel pipe pile is installed on the guide frame. The large-diameter steel pipe pile sinking fixed guide device has a reasonable structural design and is easy to operate. It can meet the precise positioning and stable piling of steel pipe pile sinking construction through a simple structure. It is very convenient to install and dismantle, and can be used repeatedly, with high construction efficiency and construction stability.

[0004] However, in the implementation of relevant technologies, it was found that the large-diameter steel pipe pile driving fixing and guiding device designed above has the following problems: the above-mentioned technical solution can meet the precise positioning and stable piling of steel pipe pile driving construction through a simple structure, and is very convenient to install and remove, and can be used repeatedly. However, it is not convenient to adjust the device during use. For example, after the pipe pile is clamped, the guide roller in the device does not contact the outer wall of the pipe pile, which causes the pipe pile to easily shift during pile driving, and has poor practicality. In view of this, a pile holding device for large-diameter steel pipe pile driving is provided to overcome the above-mentioned defects. Utility Model Content

When the bidirectional screw rotates, it drives the threaded connecting block to move, and the slide groove can ensure the normal movement of the connecting block, so that the two connecting blocks respectively drive the first pile holding member and the second pile holding member to approach each other.

[0010] As a further description of the above technical solution: a hydraulic cylinder is fixed to the upper surface of the device base by bolts, and the telescopic end of the hydraulic cylinder passes through the device base and is connected to a clamping plate. The arranged hydraulic cylinder can drive the clamping plate to move, thereby facilitating the clamping and fixing of the device.

By turning an adjusting bolt, a guide member can be pushed to move, so that a guide wheel contacts an outer wall of the pipe pile, thereby ensuring the guided pile sinking operation on the pipe pile and preventing the pipe pile from being easily offset during pile sinking. Through the guide rod and the connecting bearing, it can be ensured that the guide member will not be driven to rotate when the adjusting bolt is rotated.

[0015] The utility model designs a pile holding device for large-diameter steel pipe pile sinking. When the bidirectional screw rod rotates, it drives the threaded connection block to move.
