Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0028] refer to figure 1 , The present invention provides a simple detection device and method for a drill pipe used in the MJS construction method, which is used to detect whether the pipeline on the drill pipe is unobstructed before the drill pipe is used for construction. The drill pipe used in the MJS construction method is equipped with multiple pipelines to achieve different functions, two of which are oil pipelines, which are used to supply oil to the slurry return valve set on the drill bit to control the flow of the valve. Switch, usually the pile formed by the MJS construction method is about 100m, and the length of a drill pipe is about 1.5m. During construction, the drill bit needs to be connected with many drill pipes. If the oil pipeline on one drill pipe is blocked at this time, It will lead to the inability to control the switc...

The invention relates to a simple detection device of a drill rod for an MJS construction method, which is used for detecting whether a to-be-detected pipeline on the drill rod is smooth or not, and comprises an oil cylinder arranged at one end of the drill rod and connected with a corresponding pipe orifice on the to-be-detected pipeline; the oil supply mechanism is arranged close to the other end of the drill rod, the oil supply mechanism is connected with the other pipe orifice of the to-be-detected pipeline, and oil is supplied to the oil cylinder through the to-be-detected pipeline by the oil supply mechanism so as to drive the oil cylinder to operate. The oil cylinder and the oil supply mechanism are used for detecting the drill rod, whether a to-be-detected pipeline of the drill rod is smooth or not can be efficiently and quickly detected, mounting and dismounting are easy and convenient, only several oil pipes need to be connected, and the detection efficiency is high. The problems that in an existing detection method, installation of an MJS faucet and an MJS drill bit needs to be completed by means of a crane, time consumption is long, detection is inconvenient, and certain potential safety hazards exist are solved.
Description
technical field [0001] The invention relates to the technical field of tool detection, in particular to a simple detection device and method for a drill pipe used in an MJS construction method. Background technique [0002] The MJS (Metro Jet System) construction method, also known as the all-round high-pressure jet construction method, was originally developed to solve the problems of slurry discharge and environmental impact in horizontal rotary jetting construction. Later, due to its unique advantages and engineering needs, it was applied to Inclined and vertical construction. [0003] On the basis of the traditional high-pressure jet grouting process, the MJS construction method adopts a unique porous pipe and front-end forming device (customarily called Monitor), which realizes the forced grouting in the hole and the monitoring of the pressure in the ground, and adjusts the amount of forced grouting To control the internal pressure and greatly reduce the impact on the ...
