Abstract
The utility model discloses the embedding rock cylinder that can shake disconnected core to bore, comprise pedestal, square toes, drilling pipe, weep hole, oblique bar tooth, foundation ring, brill tooth, back-up block, corner block; Pedestal is welded with square toes, lower end is provided with drilling pipe, two centrosymmetric weep holes are provided with in the middle of drilling pipe, be provided with in clockwise acclivitous oblique bar tooth between weep hole, cylinder bores lower end and is provided with foundation ring, and foundation ring is provided with brill tooth, and the inner top side that cylinder bores is provided with back-up block, back-up block is supported with corner block, and corner block is vertical installation wide at the top and narrow at the bottom.The utility model can shake disconnected core while rotary drilling rock, improves operating efficiency.
Description
Technical field
The utility model relates to a kind of cylindrical rock and bores, and the embedding rock cylinder that especially can shake disconnected core bores.
Background technology
Rotary drilling rig is the construction machinery of pore-forming operation in a kind of applicable building foundation engineering.It is the more special drill bit of one that rotary drilling rig cylindrical rock used bores, and major advantage is that drilling depth is very fast.For bedrock formation, large erratic boulder layer and hard permafrost that hardness is larger, need first to go out annular groove by cylindrical rock drilling, coordinate augers or churning driven head just can creep into again, directly use short augers or churning driven head to hole, just more difficult.The cutting element that cylindrical rock bores can be divided into bucket tooth, pick, is applicable to soft rock and middle hard rock respectively.The Main Function that cylindrical rock bores carries out loosening to the surrounding of core in hole emptying, and creates the broken scope of freedom for entering the broken core of rock inserted bit with short screw under follow-up.But usually there will be the core that gets out still very firm, not easily shake disconnected, manually shaking disconnectedly wastes time and energy very much, shake with other machine and disconnectedly also to bother very much.
Utility model content
The purpose of this utility model be shortcoming in order to overcome prior art with not enough, the embedding rock cylinder shaking disconnected core providing simple operation operating efficiency high bores.
The utility model is achieved by the following technical programs:
The embedding rock cylinder that can shake disconnected core bores, and comprises pedestal, square toes, drilling pipe, weep hole, oblique bar tooth, foundation ring, brill tooth, back-up block, corner block; Described pedestal is welded with square toes, lower end is provided with drilling pipe, two centrosymmetric weep holes are provided with in the middle of drilling pipe, be provided with in clockwise acclivitous oblique bar tooth between weep hole, described cylinder bores lower end and is provided with foundation ring, and foundation ring is provided with brill tooth, and the inner top side that described cylinder bores is provided with back-up block, back-up block is supported with corner block, and corner block is vertical installation wide at the top and narrow at the bottom.
The utility model establishes back-up block and corner block by the inner top side of boring at cylinder, while rotary drilling rock, can shake disconnected core easily, thus improves operating efficiency, saved cost.
