Description
Technical Field
The invention relates to a tunneling system, in particular to a vertical combined type tunneling system applied to drilling operation in a marine operation environment, and belongs to the technical field of offshore wind power construction.
Background
At present, in the ocean wind power construction, a large-diameter single-pile rock-socketed drilling mode carried out by a vertical combined type tunneling system is widely applied, and factors for determining the performance of the vertical combined type tunneling system comprise ① bit pressure applied to a working face, ② efficiency of removing drilling slag of the working face by ⑤ with the maximum lifting capacity of a torque ③ drill bit provided for a drill bit, ④;
at present, the performance of the conventional tunneling system is found to have the following defects in the actual use process, namely ① bit pressure is insufficient, the bit pressure is less than or equal to 150T, ② torque is insufficient, the torque is less than or equal to 1000KN.m, ③ slag discharging efficiency is low, and only one suction port is formed;
meanwhile, in the drilling process, a plurality of sections of drill rods need to be assembled to lengthen the drilling tool so as to realize the continuous expansion of the drilling depth. After drilling is finished, the drilling tool needs to be lifted and taken out by disassembling one section of the drill rod; therefore, the drill rod is disassembled and assembled, which is a high and important link in the drilling construction.
Moreover, the conventional rock-socketed drilling equipment is operated by a crane and a manual mode, so that the efficiency is low, and the assembly effect is unsatisfactory; meanwhile, in conventional rock-socketed drilling equipment, a plurality of sections of drill rods are usually stacked on a deck platform in a horizontal mode, and can be disassembled and assembled only after being turned to a vertical state during hoisting, so that the construction efficiency is further reduced undoubtedly; the safety performance of the transverse stacking mode is poor, and particularly under the condition of severe wind and waves, the drill rod is easy to roll, so that the construction progress is influenced;
meanwhile, the conventional drilling machine adopts the principle of reduced pressure drilling to perform drilling work, namely the bit pressure of the working face of the drill bit on the rock surface is generated by completely utilizing the dead weight of the drill bit, and the bit pressure of the drill bit is often insufficient; the conventional drilling machine adopts a plurality of hydraulic motors to provide torque for the drill bit, and the torque provided by the conventional drilling machine is generally low, so that the tunneling speed of the rock-socketed drilling hole is influenced;
in addition, for the drill bit structure on the drill rod, the problems of large tool abrasion and low rock breaking efficiency are found in the practical use of the conventional drill bit in a mode of adopting one slag discharge port; due to the relationship of one slag discharge port, the distance for mud to travel to the slag discharge port of the cutter head is longer, so that the ineffective crushing of the drill bit cutter on the drilling slag is increased, the abrasion of the cutter is increased, the service life is prolonged, and the service life is shortened; meanwhile, when the conventional drill bit faces different geological environments, different cutters need to be replaced, such as a hob is needed for a rock layer, a scraper is needed for a clay layer, once the conventional drill bit meets a stratum with unknown geological conditions, the geological structure needs to be judged according to drilling parameters, and the cutters are replaced in due time, so that the construction efficiency is seriously influenced.
