Abstract
The utility model discloses a pile-forming device of a driven precast steel concrete belled pile, in particular to a pile-forming immersed tube which is an assorted immersed tube of varieties of immersed precast steel concrete belled piles. The pile-forming immersed tube is formed by a hollow tube-shaped tube body (1), bottom portions (2) of at least two guide wings (3) which are arranged circumferentially and metal pile heads (4), the bottom portions (2) are arranged at the lower end of the tube body (1), the metal pile heads (4) are arranged inside the lower ends of the bottom portions (2), the front end of the metal pile head (4) is equipped with a metal probe (5), the cross section of the tube body (1) is in circular shape, the tube body (1) is in multi-section type structure, two adjacent sections of the tube body (1) are in rivet connection via rivets (6), and the guide wings (3) are movably connected with the bottom portions (2) via screw bolts (7). The pile-forming device is convenient and flexible in using, and is extremely suitable for construction and application.
Description
Technical field
The utility model relates to a kind of pile-forming equipment of pipe sinking prefabricated steel concrete club-footed pile, and particularly a kind of pile-formation sunken tube is the supporting immersed tube of various precast reinforced concrete piles.
Background technology
In the pile foundation engineering of soft foundation, generally adopt tube-sinking cast-in-situ pile, three kinds of preformed pile and large diameter bored piles at present.And what be most widely used is tube-sinking cast-in-situ pile, when executing immersed tube is passed the weak soil layer, takes out metal pile head after reaching the design elevation hardpan, and the bottom-expanding equipment of expanded bore pile being lowered in the immersed tube cuts the earth, fetches earth again forms the expanded bore pile base cavity pocket.Can't detect immersed tube when present immersed tube is constructed at the scene and whether arrive hardpan, a kind of immersed tube is arranged at present, this immersed tube is integrally formed with the guide vane that is provided with on it, and it is very accurate to locate; Also has a kind of immersed tube that does not have guide vane of using under the less demanding situation of construction precision of being suitable at present, this immersed tube high efficiency.But, if it is just better to get up these two kinds of immersed tube structures.
The utility model content
The utility model is at the problem that above-mentioned prior art exists, and provides between a kind of rational in infrastructure, guide vane and the immersed tube to flexibly connect, can detect immersed tube and arrived the pile-formation sunken tube that hardpan, convenient construction and pipe shaft are connected firmly.
The utility model realizes that the technical scheme of purpose is: a kind of pile-formation sunken tube of accurate positioning, it is by the pipe shaft of hollow tubular, along circumferentially the bottom and the metal pile head of at least two guide vanes of setting constitute, the pipe shaft lower end is located in the bottom, metal pile head is arranged on the inside, lower end of bottom, the front end of metal pile head is provided with a metal probe, the cross section of pipe shaft is circular, pipe shaft is a multi-segment structure, by rivet, be movably connected by bolt between guide vane and the bottom between adjacent two sections pipe shafts.
The utility model compared with prior art because guide vane is provided with bolt, the bottom is provided with the screw thread that is complementary with bolt, bottom and guide vane are movably connected.When construction precision is demanding, guide vane is installed, realized accurate positioning; When construction precision is less demanding, guide vane is removed, to increase work efficiency.Easy to use flexible, be fit to very much construction and use.
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Among the figure 1, pipe shaft; 2, bottom; 3, guide vane; 4, metal pile head; 5, metal probe; 6, rivet; 7, bolt.
The specific embodiment
Below embodiment of the present utility model is described in detail in conjunction with the accompanying drawings, but protection domain of the present utility model is not limit by embodiment.
As shown in Figure 1, the structure of the utility model pile-formation sunken tube is as follows, it is by the pipe shaft 1 of hollow tubular, along circumferentially the bottom 2 and the metal pile head 4 of at least two guide vanes 3 of setting constitute, guide vane 3 is provided with bolt 7, the bottom wall week be provided with the screw thread that is complementary with bolt 7, guide vane and bottom are movably connected.Pipe shaft 1 is a multi-segment structure, rivets by rivet 6 between adjacent two sections pipe shafts 1.Pipe shaft 1 lower end is located in bottom 2, and metal pile head 4 is arranged on the inside, lower end of bottom 2, and the cross section of pipe shaft 1 is circular, and the front end of metal pile head 5 is provided with a metal probe 5.
Claims (1)
1, a kind of pile-formation sunken tube of accurate positioning, it is by the pipe shaft (1) of hollow tubular, constitute along bottom (2) that at least two guide vanes (3) circumferentially are set and metal pile head (4), pipe shaft (1) lower end is located in bottom (2), metal pile head (4) is arranged on the inside, lower end of bottom (2), the front end of metal pile head (4) is provided with a metal probe (5), the cross section of pipe shaft (1) is circular, pipe shaft (1) is a multi-segment structure, by rivet (6) riveted joint, it is characterized in that described guide vane (3) and bottom (2) are movably connected by bolt (7) between adjacent two sections pipe shafts (1).
