Abstract
The utility model discloses a constructing device for building foundation, in particular to a novel immersed tube for buildings. The novel immersed tube for building is formed by a hollow tube-shaped tube body (1) and bottom portions (2) of at least two guide wings (3) which are arranged circumferentially, the bottom portions (2) is arranged at the lower end of the tube body (1), 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) is movably connected with the bottom portions via screw bolts (7). The novel immersed tube for buildings is extremely convenient and flexible in using, and is extremely suitable for construction and using.
Description
Technical field
The utility model relates to a kind of construction foundation working equipment, particularly a kind of construction foundation working piling immersed tube.
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.
Have a kind of immersed tube at present, this immersed tube and the guide vane that is provided with on it are integrally formed, and it is very accurate to locate, and are suitable for the demanding situation of construction precision and use; Also there is at present a kind of immersed tube that does not have guide vane of using under the less demanding situation of construction precision of being suitable for.But, if can combine these two kinds of immersed tube just better.
The utility model content
The problem that the utility model exists at above-mentioned prior art, and a kind of novel architecture immersed tube is provided, thereby purpose provides between a kind of simplified structure, guide vane and the immersed tube stability that the fastness that flexibly connects, increases bearing capacity of single pile, reduces cost, increases the junction improves equipment.
The utility model realizes that the technical scheme of purpose is: a kind of novel architecture immersed tube, it constitutes by the pipe shaft of hollow tubular with along the bottom that at least two guide vanes circumferentially are set, the pipe shaft lower end is located in the bottom, the cross section of pipe shaft is circular, pipe shaft is a multi-segment structure, connect by rivet between adjacent two sections pipe shafts, be movably connected by bolt between guide vane and the bottom.
The bottom of described bottom is provided with pin-and-hole.
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, the bottom of guide vane and immersed tube is for being threaded, so under the demanding situation of construction precision with the guide vane connection on; Under the less demanding situation of construction precision, guide vane is removed, thereby enhanced productivity, save production cost.The utility model is implemented in engineering easily, is beneficial to apply.
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, pin-and-hole; 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, a kind of novel architecture immersed tube of the utility model, it constitutes by the pipe shaft 1 of hollow tubular with along the bottom 2 that at least two guide vanes 3 circumferentially are set, pipe shaft 1 lower end is located in bottom 2, guide vane 3 is provided with bolt 7, the bottom wall week be provided with the screw thread that is complementary with bolt 7, be movably connected by bolt 7 between guide vane 3 and the adopted portion 2.The cross section of pipe shaft 1 is circular, and pipe shaft 1 is a multi-segment structure, rivets by rivet 6 between adjacent two sections pipe shafts 1.The bottom of bottom 2 is provided with to be convenient to combine and the pin-and-hole 5 of throwing off usefulness with its matching used metal pile head 4.
Claims (2)
1, a kind of novel architecture immersed tube, it constitutes by the pipe shaft (1) of hollow tubular with along the bottom (2) that at least two guide vanes (3) circumferentially are set, pipe shaft (1) lower end is located in bottom (2), the cross section of pipe shaft (1) is circular, pipe shaft (1) is a multi-segment structure, connect by rivet (6) between adjacent two sections pipe shafts (1), it is characterized in that being movably connected by bolt (7) between described guide vane (3) and bottom (2).
2, a kind of novel architecture immersed tube according to claim 1 is characterized in that the bottom of described bottom (2) is provided with pin-and-hole (5).
