Device and method for quick installation of cables in drill pipe based on horizontal directional drilling survey

Abstract

The invention discloses a fast installation device and method for cables in a drill pipe based on horizontal directional drilling survey, comprising a drilling rig, a drilling rig power head and a drilling pipe. A wire disc is fixed on the outer surface, and the front end of the drill pipe is connected with the TV instrument in the hole; a short joint is connected between the drilling rig power head and the drill pipe, and the front end of the short joint connected with the drill pipe is provided with a slot, and the TV wire in the hole is provided with a slot. The inlet section of the cable is drawn out from the slot of the short joint, wound into the wire reel and connected to the electric slip ring, and then connected to the TV data acquisition equipment in the hole through the electric slip ring; the outlet section of the TV cable in the hole After passing through the drill pipe, it is connected with the television equipment in the hole. The device and method for quick installation of cables in drill pipes based on horizontal directional drilling surveys of the present invention solve the problems of wiring and threading of in-hole TVs in the horizontal directional drilling survey holes, and protect the TV cables from being worn by the well wall, Also saves threading time.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering survey, and more particularly relates to a device and method for quickly installing cables in a drill pipe based on horizontal directional drilling survey. Background technique [0002] When using horizontal directional drilling technology to conduct geological survey of tunnel engineering, it is often necessary to combine comprehensive in-hole TV and other equipment to conduct video detection of the surrounding rock lithology, rock fissures, and fracture zone distribution in the horizontal directional drilling survey hole. The surrounding rock parameter information needs to transmit the data obtained by the TV instrument in the hole to the data collection site of the hole through the cable. Therefore, it is necessary to connect one end of the cable to the video data acquisition system at the hole, and the other end of the cable to the TV instrument in the hole and send it slowly a...
