Abstract

The invention discloses a vertical combined type tunneling system. The vertical combined type tunneling system comprises a drilling rig chassis (103), a manipulator (101) is mounted on the drilling rig chassis (103), a drill rod moving device (102) is located on the upper part of the drilling rig chassis (103), two sealing platforms (104) are slidably disposed on the drilling rig chassis (103), and a drill pipe assembly (105) is vertically arranged between the two sealing platforms (104) in a clamped mode. A portal frame (106) is mounted on the drilling rig chassis (103), and a power head (108) on the portal frame (106) drives the drill rod assembly (105); and the bottom of the portal frame (106) is hinged to the drilling rig chassis (103) through a hinge pin, and both ends of a turnover cylinder (107) are separately hinged to the portal frame (106) and the drilling rig chassis (103). The vertical combined type tunneling system has the advantages of higher tunneling efficiency, bettereffect, low overall construction cost, high construction efficiency and being capable of constructing under severe weather conditions.

Description

technical field

[0001] The invention relates to a tunneling system, in particular to a vertical composite tunneling system applied to drilling operations in a marine operation environment, and belongs to the technical field of offshore wind power construction. Background technique

[0002] At present, in the construction of offshore wind power, the large-diameter single-pile rock-socketed drilling method carried out by the vertical compound tunneling system has been widely used; for the vertical compound tunneling system, the factors that determine its performance are: ① Applied ② The torque provided to the drill bit ③ The speed of the drilling tool ④ The maximum lifting capacity ⑤ The efficiency of removing drilling slag from the working face;

[0003] Nowadays, in the actual use process, it is found that the performance of conventional tunneling systems has the following shortcomings: ① Insufficient WOB, WOB ≤ 150T; ② Insufficient torque, torque ≤ 1000KN.m; ③ Low slag disc...
