Rock mass quality intelligent sensing small drilling machine system and evaluation method

Abstract

The invention relates to a rock mass quality intelligent sensing small drilling machine system and an evaluation method. The small drilling machine system comprises a drilling machine body, and a power system for providing drilling and rotation for a drilling machine is arranged on the drilling machine body; a walking shifting device for controlling the drilling machine to move and fix is arranged at the bottom of the drilling machine body; a parameter collecting and monitoring system capable of reflecting parameters while drilling is arranged inside and on the surface of the drilling machine body before leaving a factory; and a control system is connected with the parameter collecting and monitoring system, arranged on the drilling machine body, provided with intelligent analysis software and provided with a man-machine operation interface. The small drilling machine system is designed and processed based on the response rule of the drilling process to the rock mass quality, the evaluation method for obtaining the physical and mechanical characteristics and geologic structure characteristics of the rock based on the drilling engineering parameters is provided, so that the defects of long periodicity and high cost of the previous processes of sampling, packaging, sending to a laboratory for testing and the like of the rock are overcome, and the test result is more timely and reliable.

Description

technical field [0001] The present invention relates to the technical field of drilling rig system and fine detection of underground space, and more specifically relates to a small drilling rig system and evaluation method for effective acquisition of drilling machine parameters and rock mass quality evaluation, which can be widely used in tunnels, water conservancy and hydropower, road traffic , mining and other engineering survey fields. Background technique [0002] The physical and mechanical parameters and structural characteristics of rock and soil are the basic basis for the classification, stability analysis and support design of underground engineering surrounding rock. Parameters are very difficult. The current testing method is on-site drilling sampling and laboratory testing of physical and mechanical parameters of rock and soil. This process takes a long time, costs high, and the authenticity of the measured parameters is low. Mechanical parameters and structu...
