Underwater super-large-diameter annular groove construction system
The underwater super-large-diameter annular groove construction system comprises a drilling machine, a drilling jig device and a cable device, the drilling jig device comprises a positioning column, a guide mechanism and a swing mechanism, and a drilling rod of the drilling machine extends out of the lower end of the guide mechanism from top to bottom. When construction is needed, the drill jig device is vertically lowered to a to-be-constructed position through the cable device, and the lower end of the positioning column abuts against the to-be-constructed position. Then the cable device is separated from the drilling jig device, then the drilling machine is started to drill holes in the position to be constructed, the guide mechanism is driven by the swing mechanism to rotate around the positioning column, and a circle of annular groove holes can be constructed. In the construction process, the perpendicularity of the drilling jig device can be adjusted in real time through the mooring rope device, so that the perpendicularity of a drilled hole is guaranteed, the to-be-constructed position is tightly jacked through the positioning column, the stability of the drilled hole can be improved, in addition, leveling operation does not need to be conducted on an inclined seabed surface, the construction efficiency of the annular groove hole can be improved, and the construction difficulty can be reduced.
本申请公开了一种水下超大直径环形槽施工系统，包括：钻机、钻模装置、缆绳装置，其中钻模装置包括定位柱、导向机构、回转机构，钻机的钻杆自上而下从导向机构的下端伸出。当需要施工时，通过缆绳装置将钻模装置垂直下放到待施工位置，定位柱的下端顶紧在待施工位置；然后将缆绳装置与钻模装置脱离，随后启动钻机，以在待施工位置钻孔，通过回转机构驱动导向机构绕定位柱转动，即可施工出一圈环槽孔。在施工过程中，可通过缆绳装置对钻模装置实时调垂，从而保证钻孔的垂直度，而且通过定位柱顶紧待施工位置，可提高钻孔的稳定性，另外无需对倾斜的海床面进行整平作业，可以提高环槽孔的施工效率和降低施工难度。
