Abstract
The utility model discloses a slag fishing barrel for a rotary drill, which comprises a barrel body and a drill stem fixing sleeve. The drill stem fixing sleeve is fixed above an opening of the barrel body through a connection plate, a slag inlet is arranged at the bottom of the barrel body, an inclined opening is arranged on one side of the slag inlet, a slag blocking plate is positioned in the barrel body on the other side of the slag inlet, and a plurality of water seeping holes are disposed at the bottom of the barrel body. The slag fishing barrel uses the working principle of the rotary drill, the bottom of the slag fishing barrel is designed into a flat plate structure with the slag inlet, sediment slag is placed in the slag fishing barrel through rotation to be lifted out, and accordingly the problem that the thickness of sediment slag at the hole bottom cannot meet requirements of design and standard is effectively resolved.
Description
Technical field
The utility model relates to construction engineering technical field, particularly a kind of revolve to dig to bore drag for the slag tube.
Background technology
Characteristics such as rotary drilling rig is used for the bridge pile foundation construction in a large number at present, and it is fast that this rig has speed of application, and hole expansibility is little; But after the brill stake finished, the quarrel of sinking at the bottom of the hole was removed difficult, is difficult to reach design and code requirement; Because before the perfusion, the heavy quarrel of pile foundation utilizes the drill bit of Spiral digging machine to drag for quarrel, and the heavy quarrel of designing requirement pile foundation thickness must not be greater than 5cm; And the tooth tile height of the drill bit of Spiral digging machine bottom is 18cm, i.e. the stake end sinks quarrel thickness greater than 18cm, ultra design far away and code requirement; Utilize the rotary drilling rig drill bit to drag for the uncontrollable heavy quarrel of quarrel and be not more than 5cm, the sedimentation of bridge is difficult to be guaranteed.Can remove the heavy quarrel of part though adopt mud to follow slurry, also be difficult to remove for bigger heavy quarrel particle, heavy quarrel thickness is difficult to reach design and code requirement at the bottom of the hole; To not adopting mud to follow the pile foundation boring construction of slurry, except that adopting artificial the removing, do not have other effective ways at present and can use, but there is bigger potential safety hazard in artificial clear hole.
The utility model content
The goal of the invention of the utility model is: to the problem of above-mentioned existence, provide a kind of and can effectively solve at the bottom of the hole heavy quarrel thickness and be difficult to satisfy revolving of design and code requirement and dig to bore and drag for the slag tube.
The technical scheme of the utility model be achieved in that a kind of revolve to dig to bore drag for the slag tube; It is characterized in that: comprise cylindrical shell and drilling rod fixed cover; Said drilling rod fixed cover is fixed on the top of cartridge openings through junction plate, has slag inlet in said cylindrical shell bottom, and said slag inlet one side is an angle; Its opposite side, in cylindrical shell, be provided with slag trap, be provided with hole, some Qinshuis in said cylindrical shell bottom.
The utility model is described to be revolved to dig to bore and drags for the slag tube, and the barrel of its said cylindrical shell is provided with at least one group of Qinshui mouth, is provided with filter screen at said Qinshui Kou Chu.
The utility model is described to be revolved to dig to bore and drags for the slag tube, and the Qinshui mouth on its said barrel is four groups, and said four groups of Qinshui mouths are evenly distributed on around the barrel of cylindrical shell.
The utility model is described to be revolved to dig to bore and drags for the slag tube, and it is provided with the filtration silk screen at said cylindrical shell inner bottom part, and the filtering holes aperture of said filtration silk screen is less than the aperture in hole, Qinshui.
The utility model is described to be revolved to dig to bore and drags for the slag tube, and its said filter wire Netcom crosses reinforcing bar and is pressed in the cylindrical shell inner bottom part.
The utility model is described to be revolved to dig to bore and drags for the slag tube, and its said drilling rod fixed cover is provided with the drilling rod fixing hole.
The utility model utilizes the operating principle of Spiral digging machine, drags for the slabbed construction that the slag tube bottom is set to bring into cinder notch, through rotation sediment is packed into and drags for the slag tube and propose, thereby effectively solved the difficult problem that sediment thickness at the bottom of the hole is difficult to satisfy design and code requirement.
