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 in a kind of architecture foundation pile engineering the job practices of boring cast-in-situ concrete pile tube and composite foundation, especially relate to and a kind ofly once accomplish a kind of method that pile foundation construction and composite foundation are constructed with duplex tube helix drilling tool pore-forming, cast.
Technical background:
Common bored pile technology has received extensive use, but it exists slagging, mud off at the bottom of the hole, the hole of collapsing, and boring back underwater pouring makes complex process and not environmental protection.; Cast-in-place concrete tube stake is sunk to underground pile through vibrating hammer with bitubular drilling tool, and environmental protection, quick is difficult to sink to the bottom but meet than the 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, influences construction quality.The appearance of this boring cast-in-situ concrete pile tube has solved to meet than hardpan creeps into difficult problem; Solved the soil compaction effect problem; Work progress does not have sediment at the bottom of having mud off, hole, reaches construction effect economic, quick, environmental protection, and makes the scope of application of perfusion pile tube more extensive.
Summary of the invention:
The objective of the invention is to: a kind of speed of application job practices and implement the construction drilling tool of the special-purpose boring cast-in-situ concrete pile tube of this method efficiently is provided for being embedded in boring cast-in-situ concrete pile tube in the ground.
The present invention is achieved in that the job practices of boring cast-in-situ concrete pile tube of the present invention, it is characterized in that:
1. the alloy serrated knife with the duplex tube helix drilling tool is placed on the interior pipe, and inner tubal wall is provided with upper and lower key, and the upper end connects tapered cap, and tapered cap is provided with the casting mud pipe.The external surface of said drilling tool outer tube is mounted with conveyor screw; Be provided with upper and lower keyway in the outer tube pipe; Be connected with key about the interior pipe, (also can < see accompanying drawing 4>with dividing plate is connected outer tube with interior pipe), outer tube connects bottom through pivot pin; Bottom is formed by many lobes body, (bottom also can be connected < seeing accompanying drawing 4>through pivot pin with the bottom of interior pipe).Outer tube top is provided with external key, and drill power head can drive drilling tool and rotate.Outer tube top connects the cast lid, and the cast lid is placed on the cast support, and the cast lid is connected revolution and supports, and revolution is supported to go up and connected the sprue gate.
When 2. constructing, the drilling tool bottom is built in the align piles position, and drill power head rotates the drive duplex tube helix drilling tool that pressurizes simultaneously downwards and pierces desired depth in the hole;
3. start concrete pump and through gate spool concrete is got in the space of interior pipe and outer tube formation, the limit pulls up drilling tool limit fluid concrete.
When 4. pulling up the duplex tube helix drilling tool; Take part soil on the conveyor screw out of, the soil compaction effect that drilling tool is pierced produce in the process obtains discharging, and forms the concrete tubular pile of the crowded native part casting of a part; Be embedded in the ground, this plain concrete pile tube also can be used as in the ground processing of composite foundation.
5. when needs are made reinforced concrete pipe pile, can be behind casting complete reinforcing cage be inserted the cast-in-place concrete tubular pile of formation in the concrete 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: existing crowded soil has casting again when 1. creeping into, and has both improved the bearing capacity of stake, has solved undergauge broken pile problem in the work progress again; 2. because of drilling tool is that the hollow mode of being screwed into is crept into, can accomplish does not have sediment at the bottom of the hole; 3. because of not having mud off in the construction, so the construction plant is clean, quick; 4. because of being the pile tube of hollow and annular, middle cubsoil need not to get out, and under the little and drilling tool of the resistance that pierces serrated knife is housed downwards, can creep into than hardpan friction, noiselessness in the work progress; 5. because of being the ring-type pile tube, can practice thrift concrete in a large number.
