The invention discloses a positioning device and a positioning method for underwater drilling, and relates to the field of building engineering construction. The positioning device comprises a hydraulic control system, an upper working platform arranged horizontally, a lower working platform arranged horizontally, and a hoisting stand column arranged vertically. A lifting mechanism is arranged onthe upper working platform; the hoisting stand column penetrates through the upper working platform and is connected with the lower working platform; a punching driller is arranged on the lower working platform; and the punching driller and the lifting mechanism are connected with the hydraulic control system. The positioning method comprises the step of assembling the upper working platform, thelower working platform, the punching driller and the lifting mechanism; the hydraulic control system controls the punching driller to drill a hole and controls the punching driller to retreat; and thelifting mechanism adjusts the height of the hoisting stand column, so that a position of the lower working platform is re-positioned. According to the positioning device and the positioning method for underwater drilling provided by the invention, manual underwater operation is not needed, so that hole positioning can be quickly and accurately accomplished, and the working efficiency and the safety are high.
Description
technical field [0001] The invention relates to the field of building engineering construction, in particular to an underwater drilling positioning device and positioning method. Background technique [0002] When concrete structures such as underwater shafts, wharf retaining walls and caissons are dismantled and partially damaged, underwater cutting is usually adopted. This kind of underwater cutting usually needs to be cut by punching, hoisted and hoisted to other areas for processing. Among them, both cutting and hoisting work need to drill holes on the underwater concrete wall structure. The diameter of the holes is generally 80mm to 250mm, and the requirements for drilling positioning accuracy and levelness are relatively high. [0003] At present, conventional drilling positioning methods include: [0004] Method 1: Divers measure underwater and then position the drilling rig. After the divers measure the drilling hole position by hanging wires, steel rulers, etc., ...
