Rotary excavating drill based hole cleaning tool for slag removal in karst area and manufacturing and construction method thereof

Abstract

A rotary excavating drill based hole cleaning tool for slag removal in karst area comprises a circular steel plate, wherein the diameter of the steel plate is equal to that of the bottom of a drill bit of the rotary excavating drill with the drill teeth removed, an open hole with the diameter equal to that of a drill rod on the drill bit is formed in the center of the steel plate, notches are formed on the two sides of the open hole and in the steel plate and correspond to hole-free parts at the bottom of the drill bit, and the steel plate is installed at the bottom of the drill rod through the open hole. A manufacturing method comprises the steps of: all drill teeth at the bottom of the drill bit of the rotary excavating drill are detached; the steel plate is cut into a round shape according to the diameter of the drill bit; a hole is formed in the center of the steel plate according to the diameter of a drill rod on the drill bit, and notches are formed in the steel plate according to a hole-free part in the bottom of the drill bit; and the modified steel plate is mounted at the bottom of the drill bit to form a complete slag extraction tool. The construction method comprises thesteps of: after drilling is completed, the rotary excavating drill based hole cleaning tool for slag removal is used for going deep into the hole bottom; the steel plate rotates repeatedly all the time in the working process of the rotary excavating drill; and when the rotary excavating drill is closed, the steel plate stands still for half a minute and then is slowly lifted out at a constant speed for throwing out the removed slag.

Description

technical field [0001] The invention relates to a tool newly applied in rotary drilling and hole cleaning in karst areas, in particular to geology where karst is strongly developed and hole cleaning is difficult. Background technique [0002] Rotary drilling in conventional karst areas uses a mud circulation hole cleaning frame, but rotary drilling in karst areas has problems such as difficulty in cleaning holes, incomplete hole cleaning, and substandard sediment thickness. Contents of the invention [0003] Aiming at the problems and deficiencies in the prior art, the present invention provides a novel hole cleaning tool for rotary drilling and drilling ceramsite slag treatment in karst areas and a manufacturing method thereof. [0004] The present invention solves the above technical problems through the following technical solutions: [0005] The invention provides a tool for clearing holes by rotary drilling in karst areas, which is characterized in that it includes a...
