Abstract

Disclosed technology relates to a drill device comprising: a pile configured such that same descends to a seafloor surface through a mooring installation device provided in a ship, and a part of the body thereof is fixed in an area of the seafloor surface as the upper surface thereof is pressurized in the vertical direction; a driving pipe configured such that same descends to the seafloor surface through a through-hole formed in the pile, the body thereof is inserted into a seafloor foundation, and same is recovered through the through-hole after excavation is completed; a chain, one end of which is fixed to one side of the pile, and the other end of which is introduced through the through-hole such that same is inserted into the seafloor foundation together with the driving pipe; and a drill bit unit having a drill bit provided on the front portion of the body thereof and having a fastening portion formed on the rear portion of the body thereof such that an end of the driving pipe is fastened thereto, the drill bit unit being configured to insert the driving pipe and the chain into the seafloor foundation while the other end of the chain is connected to a bearing surrounding the body thereof. Accordingly, the drill device is advantageous in that the chain is prevented from being wound around the driving pipe, and the pile remains fixed by fixing the seafloor foundation with the drill bit.

Description

technical field [0001] The disclosed technology relates to a drilling device for excavating the seabed for installation of moorings secured to the seabed. Background technique [0002] Generally, mooring devices for mooring offshore structures in the sea include a mooring method of installing anchors on the seabed, a mooring method of installing driven piles, and a tension leg platform (TLP) method. [0003] These mooring devices are connected to the offshore structure through mooring chains, and play a role in supporting the buoyancy of the offshore structure due to waves. Therefore, moorings installed on the seabed need to be strong and fixed to withstand typhoons and high waves. [0004] Referring to Korean Patent Registration No. 10-1859610 (Title of Invention: Mooring Device), there is disclosed a technique of excavating a seabed using a drill bit to firmly fix a pile and inserting a chain thereon to fix the pile. However, the problem with this technique is that when ...
