Abstract
The utility model relates to a Y-H composite immersed tube casting concrete pile. The technical matter to solve is that the utility model provides a Y-H composite immersed tube casting concrete pile which can be cast on site and has moderate and over moderate size with strong shearing resistant ability and can be used to construct the continuous retaining wall underground. The technical proposal to solve the problem is that the cross-section of the Y-H composite immersed tube casting concrete pile is in the shape of H. The concrete pile is formed by an upper and lower symmetrical piles which are in the shape of 'Y' and abutted. A sternum is formed at the connection part. The Y-H composite immersed tube casting concrete pile can be used to protect the deep foundation pit such as building the continuous retaining wall underground and a single pile.
Description
Technical field
The utility model relates to the compound tube-sinking cast-in-situ pile of a kind of Y-H.Be applicable to Extra-Deep Foundation Pit, as set up underground continuous retaining wall.Also use as single stake.
Background technology
At present Extra-Deep Foundation Pit mostly adopts cylindrical immersed tube or bored pile colonnade formula retaining wall, but well-known cylindrical cast-in-place concrete pile shearing resistance, bending resistance are poor; Theoretically, shearing resistance, the bending resistance of " H " stake should be the strongest, but adopt put more energy into soil-cement barricade (SMW) rigidity for deep foundation ditch of (by force) of H shape steel still to dislike deficiency in actual use; And construct prefabricated H shape concrete pile barricade than large scale, be subjected to lifting again and the pile sinking condition is limit.
The utility model content
The technical problems to be solved in the utility model is: a kind of Y-H is provided compound tube-sinking cast-in-situ pile, and described compound tube-sinking cast-in-situ pile can cast-in-site, medium and above yardstick, and bending resistance, shear resistance are strong, can construct underground continuous retaining wall.
The technical scheme that the utility model adopted is: the cross section of the compound tube-sinking cast-in-situ pile of Y-H is " H " shape, i.e. stake is formed by the pile body butt joint that is " Y " shape of two symmetries up and down, forms web in the junction.
Each face of stake can be the cambered surface that concaves; Also can be combining of cambered surface and plane.
Its cross section, four stake angles of described stake can be wedge angle, fillet, the straight angle.
The beneficial effects of the utility model are: because the stake that the utility model relates to is to adopt the immersed tube bored method of gradation to be combined into the stake of " H " shape two " Y " shape stakes on the basis of " Y " shape tube-sinking cast-in-situ pile, so it can cast-in-site, it is medium even bigger that yardstick can reach, thereby make gravity or the non-gravity formula barricade of thickness more than one meter be used common immersed tunnelling method to implement.Therefore, the utility model is that a kind of construction cost is low, technology is simple, be shaped after strong, the new worker's method of " H " stake bending resistance, shear resistance with innovative significance.

The specific embodiment
Shown in Fig. 1-5, the cross section of the compound tube-sinking cast-in-situ pile of Y-H is " H " shape, i.e. stake is formed by the pile body that is " Y " shape 1 butt joint of two symmetries up and down, forms web 2 in the junction, and each face of stake all is the cambered surface that concaves.Each face of stake also can be designed to the face that cambered surface combines with the plane as required.
Four stake angles 3 of " H " stake can be wedge angles, also can be designed as the fillet or the straight angle.
The construction technology of present embodiment is as follows:
1) additional groove button 4 on a flange of one " Y " stake mould is squeezed into the stratum with it;
2) additional catching groove 5 on a flange of another root " Y " stake mould, catching groove 5 and groove button 4 fastenings that should be able to slide mutually, the second pile mould is relative with the first pile mould flange and by behind groove button 4 and the catching groove 5 mutual fastenings, also it is squeezed into the stratum;
3) poured concrete in the stake mould in above-mentioned two stake moulds, half pile body 1 of formation " H " stake is extracted a mould;
4) poured concrete in another mould again forms half pile body 1 in addition of " H " shape stake, extracts a mould, and two " Y " shapes stake this moment becomes the stake of " H " shape with regard to one integrated mass ground, and the handing-over position of two piles promptly is the web 2 of " H " shape stake.
The configurable longitudinal reinforcement in tension district at the pile body 1 of described " H " shape stake; And at the configurable circumferential reinforcement cage in the resistance to compression district of pile body 1.Having only at web 2 positions can't arrangement of reinforcement, but both has been that the shear strength of plain concrete can make this stake have suitable bending rigidity.
Owing to adopt mould to irritate the existing precedent of diaphragm wall,, then adopt the combined steel perfusion pile of bracelet groove can implement especially as case histories such as continuous board wall and the stakes of disjunctor tube.Concrete steps (seeing also Fig. 6) are to pour into out earlier the row agitation pile 6 of setpoint distance at interval, be used for sealing, between two agitation piles with part agitation pile overlaid pour into out " H " stake, in other words, just at two wedge angle positions of two " H " shapes stake agitation pile 6 sealings, the stake of a plurality of " H " shape has promptly constituted underground continuous retaining wall.
Also can construct " H " shape pile row wall earlier, churning cement paste between two " H " stake forms waterstop then.
