Description

TECHNICAL FIELD

[0001] The utility model relates to a pile sinking positioning device and belongs to the pile sinking positioning technical field. BACKGROUND

[0002] In the sea area with water depth of 30-50m, offshore wind power usually adopts a jacket foundation, which is composed of a jacket and four steel pipe piles inserted into the seabed, and the jacket and the steel pipe piles are connected through grouting. During on-site construction, the four steel pipe piles are usually first driven into the seabed. In order to accurately position the relative positions of the four steel pipe piles, a pile sinking positioning frame is needed to position the four steel pipe piles. During construction, the positioning frame is first placed on the seabed, and then the four auxiliary piles are inserted to fix the positioning frame on the seabed after the positioning frame is adjusted to the right position and level. Then, the engineering pile is inserted into the positioning frame guide cylinder by using a hoisting ship, and the pile is driven into the soil layer by using a hydraulic hammer. When the pile sinking is completed, the top of the jacket engineering pile is about 5m away from the mud surface. However, the hydraulic hammer is too large to pass through the positioning frame guide cylinder, and not all hydraulic hammers can be used for underwater pile driving. Therefore, when the steel pipe pile is driven below the water surface, a pile delivery device is needed to continue the pile driving. The pile delivery device is placed on the top of the steel pipe pile, and the pile driving energy is transmitted to the steel pipe pile by using the pile delivery device to realize underwater pile sinking of the steel pipe pile.

[0003] Generally, the pile delivery device is placed horizontally on the deck of a floating crane, and then it is vertically erected by using a double-machine lifting method when it is used. The pile delivery device is hoisted to the top of the pile to be driven, and then the hydraulic hammer is hoisted to the top of the pile delivery device to realize underwater pile sinking. This process needs a series of operation steps, such as placing the hydraulic hammer on the deck, changing the lifting rigging, hoisting the pile delivery device, fixing the pile lifting device to the top of the pile delivery device, hanging the hook at the tail of the pile delivery device, vertically erecting the pile delivery device by using the double-machine lifting method, removing the tail hook, inserting the pile delivery device into the pile top, detaching the pile clamping device from the top of the pile delivery device, hoisting the pile delivery device back to the deck, removing the hook, re-hoisting the hydraulic hammer, continuing the pile driving, and placing the pile delivery device back on the deck after the pile driving is completed. This process is very time-consuming and labor-intensive, and there are risks in the middle process. CONTENT OF THE UTILITY MODEL
