The invention provides a marine large-diameter tube-shaking drilling pile driving barge (machine) and a construction technology. A tube-shaking platform is arranged on a pile driving frame on a barge body and installed at the lower portion of the pile driving frame through a pin shaft. A tube-shaking beam is arranged on the tube-shaking platform. Two adjusting cushion blocks are arranged between the tube-shaking platform and the barge body. Two tube-shaking oil cylinders are horizontally arranged between the tube-shaking platform and the tube-shaking beam, and the tube-shaking oil cylinders, the tube-shaking platform and the tube-shaking beam are arranged together in a sleeved mode. A steel tube pile is inserted into a center hole of the tube-shaking beam. A multi-head drill capable of automatically moving is arranged inside the tube of the steel tube pile. A plurality of long-strip keys are arranged on the outer wall. The technology comprises the steps that the pile machine moves to be aligned with the pile position, the steel tube pile is suspended into a center hole of the pile machine, the outer wall of the immersed tube is clamped, a pile driving hammer and the tube-shaking oil cylinders conduct punching and shaking at the same time, meanwhile, the multi-head drill is suspended into the steel tube pile to conduct drilling and soil taking, and slurry stirred by the multi-head drill is discharged. After the designed depth of the pile is reached, the pile machine is withdrawn. According to the marine large-diameter tube-shaking drilling pile driving barge and the construction technology, the pile pressing resistance is greatly reduced, and the small-scale pile machine can efficiently construct the large-diameter immersed tube pile with the low cost.
Description
technical field [0001] The invention relates to a large-diameter offshore pipe pile construction machine and a construction process, in particular to an offshore large-diameter shaking tube drilling piling ship and a construction process. Background technique [0002] All offshore buildings need a good foundation, and the foundation form is mainly a pile foundation, and most of the foundation piles are steel pipe piles. Due to the deep sea water, most of the steel pipe piles used at sea are large-diameter and super-long steel pipe piles. The construction of these large-diameter and super-long steel pipe piles uses offshore piling ships (or called offshore piling machines). The resistance of large-diameter and super-long steel pipe piles is very large. These offshore piling ships are huge, very complicated, and difficult to construct. Large, high construction costs. How to reduce construction resistance, so that small-sized offshore piling ships (machines) can drive larger ...
