Embodiment Construction
[0021] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0022] A pile sinking device based on inclined piles in shallow sea dredging and filling areas, the device includes two sets of triangular support frames 1 parallel up and down, the rear end of each set of support frames is fixedly installed on the ship's side 2, and the top of the triangular support frame Shaft sleeves 3 are installed, and a rotary shaft 4 is installed between the upper and lower shaft sleeves. The upper end of the rotary shaft protrudes from the upper end surface of the upper shaft sleeve, and a polygonal shaft head 4-1 is provided on the protruding part. The shaft head is equipped with a detachable wrench; the middle position of the rotary shaft 4 is fixedly installed with an inclined bracket sleeve 5, and a locking screw 6...

The invention relates to a pile sinking device based on shallow sea reclamation area inclined piles. The pile sinking device based on shallow sea reclamation area inclined piles is characterized by comprising two triangular supporting frames, a shaft sleeve and a revolving shaft, wherein the upper end of the revolving shaft extends out of the upper end surface of the upper shaft sleeve, a polygonal shaft head is arranged at the extending part and provided with a detachable spanner, an inclined supporting frame sleeve is fixedly installed in the middle of the revolving shaft, and the shaft sleeve is provided with a locking screw in a penetrating mode. The pile sinking device is used for finishing a pile sinking method of the inclined piles, and the pile sinking method comprises the steps of (1) construction preparation, (2) positioning of a flat barge, (3) positioning of the inclined piles through the pile sinking device, (4) in-place pile sinking through an excavator after positioning. The process of the construction method is easy, convenient and high in maneuverability, effectively resolves the problems that pile driving barges and other equipment can not carry out construction in shallow waters, can effectively carry out pile driving of the inclined piles on the seabed, and largely saves construction cost at the same time. In addition, the pile sinking device has the advantages of being simple in structure, being convenient to install and use, improving work efficiency, lowering labor intensity and the like.
Description
technical field [0001] The invention belongs to the technical field of pile sinking for inclined piles in shallow sea dredging and reclamation areas, in particular to a pile sinking device and a pile sinking method for inclined piles in shallow sea dredging and reclamation areas by using a flat barge and an excavator. Background technique [0002] Slanting pile sinking is a common operation method in offshore operations. When setting the inclined pile, the angle of the inclined pile cannot be controlled. Therefore, the inclined pile can only be constructed according to the inclined pile construction method after determining the plane position of the inclined pile head, and then the excavator is used to adjust the inclined pile. If the angle meets the requirements, not only the construction is cumbersome, but the construction quality cannot be guaranteed. When the angle of the inclined pile is adjusted by the excavator, the disturbance of the mud layer by the inclined pile wil...
