Problems solved by technology
[0005] However, at present, none of the domestic high-pressure rotary grouting drilling rigs is equipped with a complete parameter monitoring system; and there is no domestic manufacturer specializing in the complete set of parameter monitoring technology for high-pressure rotary grouting. Parameters such as nozzle depth and nozzle depth are completely dependent on manual observation, with large errors and low efficiency; parameters of background equipment such as mud pressure, mud flow, and air pressure cannot be obtained by front-end drilling rig operators, and they cannot operate the drilling rig reasonably

The invention relates to a high-pressure rotary jet grouting parameter monitoring system and method, and a high-pressure rotary jet drilling machine. The monitoring system comprises a data processing module (4), a drilling parameter detection module (5) and / or a grouting parameter detection module (6), wherein the drilling parameter detection module (5) is used for detecting drilling machine operation parameters in the rotary jet process of the high-pressure rotary jet drilling machine; the grouting parameter detection module (6) is used for detecting fluid parameters in the rotary jet process; and the data processing module (4) is used for receiving and processing detection results from the parameter detection module (5) and / or the grouting parameter detection module (6) to obtain multiple operating parameters of the high-pressure rotary jet drilling machine. The monitoring system can obtain key parameters in the high-pressure rotary jet grouting process in real time to conveniently control the quality of a rotary jet pile; and the accuracy and the efficiency of quality monitoring of the rotary jet grouting pile can be improved, so that adjustment measures can be taken timely when abnormalities occur in the construction process, and therefore, the construction quality is ensured.
Description
technical field [0001] The invention relates to the technical field of high-pressure rotary jet grouting, in particular to a high-pressure rotary jet grouting parameter monitoring system and method, and a high-pressure rotary jet grouting drilling rig. Background technique [0002] High-pressure rotary grouting piles have been widely used in various foundation projects, such as building foundations, foundation pit enclosure, shield entry and exit reinforcement, embankment seepage prevention, existing building foundation reinforcement, slope reinforcement, tunnel advance support, etc. . [0003] The high-pressure rotary grouting drilling rig is the key construction equipment for the high-pressure rotary grouting pile, and it cooperates with the high-pressure mud pump, high-pressure water pump or air compressor to complete the high-pressure rotary grouting construction. High-pressure jet grouting technology is to use a drilling rig to drill a grouting pipe with a nozzle into ...
