Description
Technical field
The utility model relates to building pile foundation device field, and specifically a kind of building is revolved and dug pile foundation construction clear hole target drill.
Background technology
Building pile foundation revolve drilling construction technique receives the favor of engineering circles soon because of its pile-forming speed, but present stage, there is its larger problem in revolve drilling construction, pile foundation heavy quarrel thickness is difficult to control, and has exceeded the regulation of existing standards of acceptance more, has very easily caused static load test.
Therefore, the purpose of this utility model is that a kind of building pile foundation revolve drilling construction scouring bit of research and development is guaranteed that hole sinks quarrel clearly and met code requirement.
Utility model content
In view of this, the purpose of this utility model sinks the requirement of quarrel thickness acceptance criteria at the bottom of to be that development is a kind of guarantee to reach.Effectively avoid because pile foundation hole cleaning is not in place, the pile foundation revolve drilling construction scouring bit of the pile foundation quality problem that heavy quarrel thickness exceeds standard and causes.
A kind of pile foundation revolve drilling construction scouring bit of the present utility model, the drilling rod comprising scouring bit body and be coaxially fixedly connected with described scouring bit body; Described scouring bit body comprises outer barrel, inserts the center-pole in described outer barrel and be fixed on described center-pole external cylindrical surface and the helical blade be contained within described outer barrel vertically; Described drilling rod is fixed on described center-pole;
Further, described center-pole one end is provided with square-section slot, and described drilling rod one end is provided with the linkage section that coordinates with this slot and this linkage section is fixedly connected with center-pole by a steady pin;
Further, described outer barrel lower surface is provided with breast hole; Described helical blade extends outer barrel from described breast hole;
Further, described center-pole is provided with terminal pad, is provided with trip bolt between described outer barrel upper surface and described terminal pad;
Further, described center-pole lower end is provided with top for what thrust in boring mud.
The beneficial effects of the utility model: pile foundation revolve drilling construction scouring bit of the present utility model, the device highly versatiles such as the drilling rod arranged with existing rotary drilling rig, during use, can replace at any time and creep into and scouring bit, clear hole fast, be applicable to the construction technology such as holing with slurry wall protection and dry drilling, and at the bottom of guaranteeing to reach, sink the requirement of quarrel thickness acceptance criteria.Effectively avoid because pile foundation hole cleaning is not in place, the pile foundation quality problem that heavy quarrel thickness exceeds standard and causes.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is drill bit helical blade schematic diagram of the present utility model;

Detailed description of the invention
Fig. 1 is drill bit helical blade schematic diagram of the present utility model, Fig. 2 is drill bit baseplane of the present utility model schematic diagram, as shown in the figure, the pile foundation revolve drilling construction scouring bit in the present embodiment, the drilling rod 1 comprising scouring bit body and be coaxially fixedly connected with described scouring bit body, described scouring bit body comprises outer barrel 6, inserts the center-pole 7 in described outer barrel 6 and be fixed on described center-pole 7 external cylindrical surface and be contained within the helical blade 5 in described outer barrel 6 vertically, described drilling rod 1 is fixed on described center-pole 7, pile foundation revolve drilling construction scouring bit of the present utility model, the highly versatile such as device such as drilling rod 1 grade arranged with existing rotary drilling rig, during use, can replace at any time and creep into and scouring bit, clear hole fast, be applicable to the construction technology such as holing with slurry wall protection and dry drilling, and at the bottom of guaranteeing to reach, sink the requirement of quarrel thickness acceptance criteria, boring mud is screwed in the clear quarrel of realization in outer barrel 6 by rotating forward of drill bit by scouring bit, reversely rotate drill bit after being elevated above the soil by scouring bit the boring mud in scouring bit is cleared out, so repeatedly realize scarfing cinder.Effectively avoid because pile foundation hole cleaning is not in place, the pile foundation quality problem that heavy quarrel thickness exceeds standard and causes.
In the present embodiment, described center-pole 7 one end is provided with square-section slot 3, described drilling rod 1 one end is provided with the linkage section 2 that coordinates with this slot 3 and this linkage section 2 is fixedly connected with center-pole 7 by a steady pin 11, during connection, this linkage section 2 is inserted in slot 3, linkage section 2 and slot 3 sidewall are established wearing connecting hole, and steady pin 11 achieves a fixed connection through this connecting hole.
In the present embodiment, described outer barrel 6 lower surface is provided with breast hole 12; Described helical blade extends outer barrel 6 from described breast hole 12, and after rotating scouring bit, the helical blade stretched out utilizes the principle of helical feed to be delivered in outer barrel 6 by boring mud.
In the present embodiment, described center-pole 7 is provided with terminal pad 4, trip bolt 10 is provided with between described outer barrel 6 upper surface and described terminal pad 4, stretch in boring carry out clearly hole time, trip bolt 10 can be utilized outer barrel 6 and center-pole 7 to be fixed, after boring mud being filled up outer barrel 6, dismountable trip bolt 10, center-pole 7 and outer barrel 6 are relatively rotated, thus the boring mud in outer barrel 6 is discharged, or directly outer barrel 6 removed from center-pole 7, artificial deslagging, described urceolus upper surface is provided with for discharging air and mud steam vent 9.
In the present embodiment, described center-pole 7 lower end is provided with for thrusting top 8 in boring mud, utilizes this top 8 scouring bit body can be thrust in boring mud completely.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
