Description

Technical Field

[0001] The utility model relates to a device for controlling the positioning accuracy of inclined pile sinking. Background Art

[0002] Slanted piles are a common type of wharf foundation. These piles must be driven into the seabed to a certain depth. To ensure their slope and relative position deviation meet the designed values ​​after sinking, their positioning accuracy must be controlled both before and during the sinking process.

[0003] When carrying out inclined pile driving operations, an auxiliary platform temporarily fixed to the sea is required. A guide limit device is generally installed around the inclined pile mouth on the top floor of the auxiliary platform. The guide limit devices currently on the market are mainly suitable for inclined piles of a single diameter. When the diameter of the inclined pile changes, the guide limit device needs to be modified before it can continue to be used. The modification of the guide limit device is relatively complicated, the cycle is relatively long, and the construction difficulty is relatively large. In addition, the guide limit devices currently on the market are at a high height above the auxiliary platform, and the height direction is generally composed of multiple assemblies. At the end of the pile driving process, the upper assembly needs to be disassembled to lower the height of the device before continuing to drive the pile. The operation is cumbersome and the pile driving efficiency is low. Utility Model Content
