Embodiment Construction

[0033] As shown in the figure, the specific implementation method is as follows:

[0034]A hydraulic hole reaming system, comprising a water source 1, a connecting pipe 2, a water pump 3, a water supply joint 4, a drill bit 6 and a drill pipe 5, the drill bit 6 and the water supply joint 4 are respectively installed at both ends of the drill pipe 5, and the water supply joint 4 is connected to the On the outlet of the water pump 3, the water inlet of the water pump is communicated with the water source through a connecting pipe. The drill bit 6 includes a drill bit upper body 609, a gauge part 608 and a drill bit crown 607. The gauge part 608 is arranged on the drill bit upper body 609, fixed The cutting teeth 605 on the scraper 601 of the gauge part 608 constitute the drill bit crown 607, and the water pump 3 provides cooling water for the drill bit 6 and flows out from the water outlet 603. The scraper 601 of the gauge part 608 is provided with three sets, and A chip removal...

Abstract

The invention discloses a water conservancy reaming system which comprises a water source, a connecting pipe, a water pump, a water supply connector, a drill bit and a drill rod, wherein the drill bit and the water supply connector are mounted at the two ends of the drill rod; the water supply connector is connected to the outlet of the water pump; the water inlet of the water pump is communicated with the water source through the connecting pipe. According to the water conservancy reaming system, the performance of the whole system is improved by improving parts in the integral structure, and the technical problems caused by specific parts are solved.

Description

technical field [0001] The invention relates to a hole reaming device, in particular to a hydraulic hole reaming system. Background technique [0002] According to the mine gas control plan, the gas concentration in the borehole often fails to achieve the expected effect by using the existing gas drainage measures, mainly because the coal seam has poor air permeability. Through experimental research, the construction essentials of hydraulic punching, hydraulic punching And its anti-burst mechanism, studies have shown that the use of floor rock roadway through-layer drilling and hydraulic punching area anti-burst measures can effectively eliminate outburst stress, greatly increase the air permeability of the coal seam, and ensure safe and efficient mining of the working face. [0003] When adopting hydraulic punching, it is necessary to constantly replace the drill pipe bit, because at the beginning, the drill bit is used to drill the hole with low-pressure water, and then th...
