Intelligent drill boom of drill jumbo and rock mass quality detection and evaluation method

Abstract

The invention belongs to the technical field of tunnel construction equipment. An intelligent drill boom of a drill jumbo comprises a propelling beam, a drilling assembly, a hydraulic system, sensors and a data acquisition and processing system, wherein the drilling assembly is arranged on the propelling beam and reciprocates along the propelling beam; the hydraulic system is connected with the drilling assembly and drives the drilling assembly to act; the multiple sensors are arranged on the propelling beam, the drilling assembly and the hydraulic system and used for detecting data information in the drilling process; and the data acquisition and processing system is used for recording data information of the sensors and processing and displaying the data. The invention further discloses a rock mass quality detection and evaluation method. According to the intelligent drill boom of the drill jumbo and the rock mass quality detection and evaluation method, the drilling tool response parameters in the rock drilling process can be recorded in real time through the intelligent drill jumbo drill boom, the quality of the rock mass in front of the tunnel face is evaluated, and therefore the efficient and convenient intelligent drilling technology is achieved, and the urgent requirement of tunnel and underground engineering drilling and blasting method construction for quality obtaining is met.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction equipment, and in particular relates to an intelligent drilling arm of a rock drilling jumbo and a rock mass quality detection and evaluation method. Background technique [0002] In tunnel construction, the drill and blast method has become the main method of excavation for large-section tunnels because of its strong applicability, economy and reliability. Drilling and blasting construction can be divided into five main processes: face drilling, charge blasting, slag removal, erection and wet spraying. In the whole construction, drilling is the first step, and the process of drilling The nature of the rock mass in front of the subface is particularly important, and will largely determine the specific implementation process and parameter optimization of subsequent construction. During the construction of tunnels and underground projects, the parameters of the rock samples are often de...

Problems solved by technology

To a certain extent, this method is difficult to ensure the quickness of indoor test results, and it is even more difficult to ensure the identity of the indoor environment and on-site construction conditions.

[0003] Most of the tests in the existing technology are sampling tests, which cannot obtain the same effective results as those on the spot, resulting in low data reliability; although on-site data collection also exists, the collected data is messy, poor in continuity, and the analysis and evaluation methods are unreasonable , both lead to greater uncertainty in the subsequent rock mass quality assessment, and have little guiding effect on subsequent construction operations, often unable to achieve further optimization
