The invention relates to a method for sinking vertical piles in a shallow sea reclamation area. The method is characterized by comprising steps as follows: (1), construction preparation; (2), positioning of a flat-bed barge: a, a magnetic detector is adopted for detecting the actual walking direction of a pipeline according a pipeline layout drawing, an accurate pipeline location plan is drawn according to detected data, and a background document graph for assisting a GPS (global positioning system) is planned accordingly; b, the barge is stationed and positioned according to the background document graph, a pile location operation point is marked on a board on one side of a working face of the flat-bed barge, and the GPS is guided; c, after the flat-bed barge is positioned, a surveyor's pole is manually inserted for second detection, the location of the pipeline is marked on the spot, and four anchors are adopted for positioning in the direction in which the mark is perpendicular to an axis of the pipeline; and (3), vertical pile sinking: after the flat-bed barge is stationed in place, an excavator is used for lifting the piles, a limiting device on the board of the barge is used for limiting, and the piles are sunk in place row by row by the excavator in the axis direction of a pipeline by shifting the anchors. The construction method is simple and convenient, high in operability and capable of effectively solving the problem that equipment such as a pile driving barge cannot work in a shallower water area and effectively piling the vertical piles into the seabed, and simultaneously, the construction cost is saved greatly.
Description
Technical field [0001] The invention belongs to the technical field of pile-sinking of vertical piles in shallow sea dredger reclamation areas, and in particular relates to a method for pile driving of vertical piles in shallow sea dredger reclamation areas by using a flat barge and an excavator. Background technique [0002] In the shallow sea hydraulic reclamation, wooden piles and cover plates are used to protect the submarine pipelines passing through the hydraulic reclamation area through the method of load graded transition. Because the construction is in the shallow sea hydraulic reclamation construction area, the construction machinery used is greatly affected. Restrictions, the existing construction ships (such as piling ships) cannot play a role in relatively shallow waters, nor can they achieve precise positioning. Especially for this kind of protective construction for submarine pipelines, deviations are likely to occur Due to safety accidents, there is an urgent need...
