Abstract
Disclosed are a construction method for drilling cast-in-place concrete pipe pile and a drilling tool for concrete pipe pile. The drilling tool comprises a drilling machine, a power head, an inner pipe, an outer pipe, a screw, a bottom cover, a cast pipe and the like. When in operation, the power head of the drilling machine rotates to drive a double-pipe spiral drilling tool to drill into a hole by a preset depth, a concrete pump is started to lead concrete to enter an annular space formed by the inner pipe and the outer pipe, the screw brings out part of soil while the double-pipe spiral drilling tool is pulled out, and a plain concrete pipe pile partially for compacting and partially for discharging is formed and is embedded into a foundation. Alternatively, a steel reinforcement cage can be inserted afterwards to form a concrete pipe pile with steel reinforcements. The drilling tool solves the problems of hole shrinkage, pile breakage and difficulty in drilling during construction, sediments at the bottom of the hole and mud retaining walls on a construction site can be omitted, vibration and noise during construction is avoided, construction is rapid and environment-friendly, and a large amount of concrete can be saved.
Description
Technical field:
The present invention relates to hole in a kind of architecture foundation pile engineering construction method of cast-in-situ concrete thin-wall pipe pile and composite foundation, especially relates to a kind of a kind of method that once completes pile foundation construction and Composite foundation construction with duplex tube helix drilling tool pore-forming, cast.
Technical background:
Common bored pile technique has been subject to extensive use, but it exists slagging at the bottom of hole, mud off, collapse hole, and after boring, underwater pouring makes complex process and not environmental protection.Cast-in-place concrete tube stake is sunk to underground pile by vibrating hammer by bitubular drilling tool, and environmental protection, quick, is difficult to sink to bottom but meet compared with hardpan drilling tool, and range of application is limited; Also there are the problems referred to above in traditional prefabricated tubular pile, and takes over problem loaded down with trivial details and that soil compaction effect is serious, affects construction quality.The appearance of this boring cast-in-situ concrete thin-wall pipe pile has solved to meet creeps into difficult problem compared with hardpan, solve soil compaction effect problem, work progress without mud off, hole at the bottom of without sediment, reach economical, fast, the construction effect of environmental protection, and it is more extensive to make to pour into the scope of application of pile tube.
Summary of the invention:
The object of the invention is to: provide a kind of speed of application construction method and implement the construction drilling tool of the special boring cast-in-situ concrete thin-wall pipe pile of the method efficiently for being embedded in boring cast-in-situ concrete thin-wall pipe pile in ground.
The present invention is achieved in that the construction method of boring cast-in-situ concrete thin-wall pipe pile of the present invention, it is characterized in that:
1. the alloy serrated knife of duplex tube helix drilling tool is placed in inner tube, on inner tubal wall, be provided with, lower key, upper end connects tapered cap, in tapered cap, be provided with casting mud pipe, the external surface of described drilling tool outer tube is mounted with conveyor screw, in outer tube pipe, be provided with, lower keyway, be connected with the upper and lower key of inner tube, (also can outer tube be connected with inner tube with dividing plate), outer tube connects bottom by pivot pin, bottom is formed by many lobes body, (bottom also can be connected with the bottom of inner tube by pivot pin), outer tube top is provided with external key, drill power head, can drive drilling tool to rotate.Outer tube top connects cast lid, and cast is covered and is placed on cast support, and it is upper that cast lid is connected to revolution support, and upper connection sprue gate is supported in revolution.
2. while construction, drilling tool bottom is built in align piles position, and drill power head rotates simultaneously pressurization downwards and drives double tube spiral drill tool to pierce desired depth in hole;
8. start concrete pump and by gate spool, concrete is entered in the space of inner tube and outer tube formation, limit pulls up drilling tool limit fluid concrete.
4. when pulling up duplex tube helix drilling tool, on conveyor screw, take part soil out of, the soil compaction effect that drilling tool is pierced produce in process is discharged, and forms the concrete tubular pile of part soil compaction part casting, be embedded in ground, this plain concrete pile tube also can be used as in the ground processing of composite foundation.
5. in the time that needs are made reinforced concrete pipe pile, can after casting complete, reinforcing cage be inserted in concrete and form cast-in-place concrete tubular pile in ground.
Good effect of the present invention is: this drilling tool can make the on-the-spot mold of concealed work, and construction quality is fully protected.Be embodied in: while 1. creeping into, existing soil compaction has again casting, both improved the bearing capacity of stake, solved again undergauge broken pile problem in work progress; 2. because drilling tool is that hollow is screwed into mode and creeps into, can accomplish at the bottom of hole without sediment; 3. because of in construction without mud off, therefore construction plant is clean, fast; 4. because being the pile tube of hollow and annular, middle cubsoil is without getting out, and under the little and drilling tool of the resistance that pierces, serrated knife is housed downwards, can creep into compared with hardpan friction, noiselessness in work progress; 5. because being ring-type pile tube, can save in a large number concrete.
