Abstract

The invention discloses a rapid installation device and method for cables in a drilling rod based on horizontal directional drilling investigation. The device comprises a drilling machine, a drillingmachine power head and the drilling rod; an electric slip ring is arranged between the drilling machine and the drilling machine power head; a wire coil is fixed to the outer surface of the drilling machine power head; the front end of the drilling rod is connected with an in-hole television instrument; a short joint is connected between the drilling machine power head and the drilling rod; an open groove is formed in the front end, connected with the drilling rod, of the short joint; an inlet section of an in-hole television cable is led out from the open groove of the short joint, is connected with the electric slip ring after being wound into the wire coil and then is connected with in-hole television data acquisition equipment through the electric slip ring; and the outlet section of the in-hole television cable penetrates through the interior of the drilling rod and then is connected with the in-hole television instrument. According to the rapid installation device and method forthe cables in the drilling rod based on horizontal directional drilling investigation, the problems of wiring and threading of an in-hole television in a horizontal directional drilling investigationhole are solved, the television cable is protected against the abrasion of a well wall, and threading time is saved.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering survey, and more specifically relates to a device and method for quickly installing cables in drill pipes based on horizontal directional drilling survey. Background technique [0002] When horizontal directional drilling technology is used to carry out geological survey of tunnel engineering, it is often necessary to combine comprehensive in-hole TV and other equipment to conduct video detection of surrounding rock lithology, rock cracks and fracture zone distribution in horizontal directional drilling survey holes. Surrounding rock parameter information needs to transmit the data obtained by the in-hole TV instrument to the data collection point of the hole through the cable, so one end of the cable needs to be connected to the video data acquisition system at the hole, and the other end is connected to the in-hole TV instrument to be sent slowly along with the drill pipe. This ...
