Abstract
A press-in caisson pile device comprises a clamper and a press-in device. The utility model is characterized in that the device is provided with a tool steel pile which is used with the clamper and the press-in device, the tool steel pile is composed of a pile body and a pile tip, the pile body is a pile style hollow barrel which is connected with the taper-shaped pile tip. The superiority of the utility model is that the novel pile of extrusion pore-forming and perfusion molding not only has pile tip bearing capacity of a higher press-in pile which is preformed, but also has higher lateral pile resistance which is intrinsic to a site caisson pile, and the utility model not only has the advantages of rapid construction of a driven pile and no mud pollution, but also has the advantages of the existing caisson pile of simplicity, flexibility and strong adaptability.
Description
(1) technical field:
The utility model relates to a kind of building operations facility, and particularly a kind of static pile press that utilizes is implemented the compact making hole press-in bored concrete pile device of concrete perfusion pile on the spot.
(2) background technology:
At present, the static pile press in the pile foundation engineering can only be used for being pressed into preformed pile.But preformed pile needs prefabricated and transportation, has increased the cost of stake.The length of preformed pile is subjected to the strictness restriction of control of traffic and road in addition, and every length can not surpass 10 meters, for the stake of the degree of depth greater than 10 meters, needs on-the-spot pile extension, and is time-consuming.
(3) summary of the invention:
The purpose of this utility model is to design a kind of press-in bored concrete pile device, and it can overcome above-mentioned shortcoming, realizes concrete cast-in-situ pile, thereby has avoided important steps such as the prefabricated of preformed pile and transportation; The long restriction that is not subjected to communications and transportation of stake; Both reduce the pile foundation engineering cost, and can improve bearing capacity of single pile again.
The technical solution of the utility model: a kind of press-in bored concrete pile device, comprise clamper and press-in device, it is characterized in that one tool-type piling bar being arranged with clamper and the supporting use of press-in device, said tool-type piling bar is to be made of pile body and stake point, pile body is a shape hollow cylinder, is connected with taper stake point with stake shape hollow cylinder.
The above-mentioned said taper stake point that is connected with stake shape hollow cylinder can be a solid concrete stake point, also can be hollow movable stake point; Said hollow movable stake point can be hinged pile shape hollow cylinder bottom, flap tip.
Above-mentioned said pile body side is provided with the hole that flows into for concrete
The section of above-mentioned said tool-type piling bar can be done squarely, circle, annular, cross, polygon or other practical shapes.
Above-mentioned said press-in device comprises oil pressure cylinder, vibrator or vibro driver.
The course of work of the present utility model and operating principle are: this device is to use jointly with pile press, at first, by clamper, piling bar is pressed in the soil.The formed hole of piling bar extrusion soil is filled with concrete immediately.Piling bar continues to be pressed into, and concrete constantly replenishes, until desired depth.Extract piling bar then, solid concrete stake point then solidifies pile jointly together with the concrete that is trapped in the hole in this way; Hinged in this way hollow movable stake point then can be extracted in the lump with piling bar.The function of clamper is that pressure with pile press passes to piling bar in the device, and it is underground that piling bar relies on this pressure just can be pressed into; The effect of vibrator is 1. to reduce soil to the frictional resistance of piling bar, 2. increase the penetration capability of piling bar, 3. vibratory compaction concrete.Piling bar is as instrument, and is reusable, remakes the operation of next pile with it.
Superiority of the present utility model is: 1, the higher sharp bearing capacity of stake of the existing prefabricated pressure pile of novel system stake device of this compact making hole, pour-shaping, have concurrently again in situ pile intrinsic higher pile side friction; 2, existing driven pile rapid construction, do not have the advantage of mud contamination, have simple and easy, flexible, the adaptable strong point of cast-in-plase pile again concurrently; 3, the long restriction that is not subjected to bill transport path of stake, thereby do not need on-the-spot pile extension; 4, can the construct stake in various cross sections; 5, can obtain higher bearing capacity.
