Description

A kind of pile foundation construction drilling equipment being applicable to karst area
Technical field
This utility model belongs to drilling operation apparatus field, is specifically related to one and is applicable to karst region The pile foundation construction drilling equipment in district.
Background technology
In prospecting boring and pile foundation construction boring procedure, karst area can be run into, typically use Method that first slip casting is holed again or use lower multilayer sleeve drilling process, but complex process, both Increase cost, reduce again effect.
Utility model content
This utility model provides a kind of pile foundation construction drilling equipment being applicable to karst area, it is possible to Once multilamellar karst is passed through in boring, had both saved cost, and had improved again work efficiency, and technique is simple, it is simple to Constructor grasps.
The technical solution of the utility model is as follows:
A kind of pile foundation construction drilling equipment being applicable to karst area, including rig, drilling rod, stake Drill, reaming bit, main sleeve pipe and inner sleeve, described diameter of ream bit is than described main set The big 1-3mm of pipe external diameter;Described main sleeve pipe is used for following reaming bit and passes through rock stratum, until under The seat rock of end solution cavity is completely located;Described inner sleeve puts into described main internal surface of sleeve pipe, is used for watering Build concrete pile;Described main casing recovery reuses.
The described pile foundation construction drilling equipment being applicable to karst area, the wherein said main set thickness of pipe Degree is 10-20mm, and described inner sleeve thickness is 1-3mm.
The described pile foundation construction drilling equipment being applicable to karst area, wherein said main sleeve pipe it Between use screwed connection.
The described pile foundation construction drilling equipment being applicable to karst area, wherein said inner sleeve it Between use and be welded to connect.
The beneficial effects of the utility model are:
1, the pile foundation pore-forming of karst area, particularly multilamellar karst strata, uses pipe-following drilling With reaming bit technique can disposal pore-forming, without solution cavity slip casting, multilayer sleeve, efficiency is high, Cost is low.The pile foundation construction pore-forming preferably solving special multilamellar karst area, karst area is stranded Difficulty, uses the problem that single control measures cannot prove effective.
2, during pile foundation construction, after main sleeve pipe is combined construction formation stake holes with reaming bit, Put into inner sleeve at main internal surface of sleeve pipe, now reclaim main sleeve pipe, then carry out concreting;In Casing wall is thin, connects with welding manner, saves construction cost.

Fig. 1 is to be applicable to the pile foundation construction drilling equipment of karst area to creep into the construction shape of soil layer State figure;
Fig. 2 is to be applicable to the pile foundation construction drilling equipment of karst area to creep into the construction shape of rock stratum State figure;
After Fig. 3 is the pile foundation construction drilling equipment drill-through bottom solution cavity being applicable to karst area Construction State figure;
Fig. 4 be in Fig. 3 A-A to profile.
Detailed description of the invention
As shown in figures 1-4, a kind of pile foundation construction drilling equipment being applicable to karst area, including Rig 1, drilling rod 2, stake holes drill bit 6, reaming bit 7, main sleeve pipe 3 and inner sleeve 4, institute State reaming bit 7 diameter than the described main sleeve pipe 3 big 1mm of external diameter;Described main sleeve pipe 3 for Rock stratum is passed through, until the seat rock of bottom solution cavity is completely located with reaming bit 7;In described Described main sleeve pipe 3 inwall put into by sleeve pipe 4, for casting concrete pile;Described main sleeve pipe 3 Recycle and reuse;Wherein said main sleeve pipe 3 thickness is 15mm, and described inner sleeve 4 thickness is 2mm;Screwed connection is used between wherein said main sleeve pipe 3;Adopt between wherein said inner sleeve 4 With being welded to connect.
The construction procedure of the above-mentioned pile foundation construction drilling equipment being applicable to karst area is as follows:
One, first drilling equipment utilizes stake holes drill bit 6 normally to creep into soil layer, this most main sleeve pipe 3, Artificial or twisting machine down tube, when arriving rock stratum when, changes reaming bit 7 by stake holes 5 hole Footpath expands, and drilling diameter is more than main sleeve pipe 3 external diameter 1mm, it is ensured that main sleeve pipe 3 can be with reamer 7 enter rock stratum.
Two, get into the bottom of bottom solution cavity, if lower rock is complete, recover stake holes drill bit the most again 6 hole diameters are design stake footpath, without pipe-following drilling, until it reaches till absolute altitude at the bottom of design stake.
Three, after stake holes 5 reaches to design hole depth, hole flushing, stake holes drill bit 6 is extracted, by inner sleeve 4 put into stake holes 5 inside main sleeve pipe 3.
Four, after inner sleeve 4 is put into, main sleeve pipe 3 is extracted, disassembles, prepare to recycle.
Five, after bore process is fully completed, descending reinforcing cage, concrete perfusion, implement pile foundation construction Follow-up work.
