The specific embodiment
Below in conjunction with specification drawings and specific embodiments the present invention is used for supporting caisson structure in open caisson construction interior supporting pile is described in further detail.
As shown in Figure 2, supporting pile is made up of several stake joints 21 in the present invention, is installed together by dismountable mode between each joint 21.Need to prove in the present invention, the cross section of adjacent two stakes joint 21 should be congruent, promptly ledge can not occur,, can sink cause certain resistance by internal supporting pile because ledge is unfavorable for the interior sinking of supporting pile in soil layer in the position of two stake joints combination.Provided a kind of detachable mounting means among Fig. 2, Fig. 3 a and Fig. 3 b, in the present embodiment, stake joint 21 flanges 212 that comprise round steel pipe 211 and be installed in the round steel pipe two ends, the shape of steel pipe 211 is not limited to be circle in the specific implementation, also can select the steel pipe of other shapes (as rectangle) as the case may be.Be fixed together by the bolt 213 that passes circular hole 214 on the flange 212 between adjacent two stakes joint 21, inboard at flange 212 is fixed with nut 215 corresponding to each flange hole 214, in the present embodiment, before mounting flange 212, nut 215 is welded on flange 212 inboards in advance.Lower end of saving at lowermost end is equipped with stake point 22.Habitual flange arrangement is adopted at stake joint 21 two ends in the present embodiment, the two ends of the round steel pipe 211 that flange 212 can directly be welded, and structure is very simple, processing and manufacturing easily.
Be shown supporting pile in the present invention as Fig. 4 and be applied in schematic diagram in the caisson structure, in this figure, by being positioned at supporting pile 2 and the 4 controlled sinkings of jack 3 supporting caisson structures below the interlaced beam in length and breadth.During construction, at first squeezed into the interior supporting pile 2 of predetermined quantity in advance, in the process of piling, needed earlier several joints 21 to be combined at underground.The structure and the geological condition of open caisson depended in the submergence depth of interior supporting pile 2, quantity and distribution.After supporting pile 2 is squeezed into desired depth in treating, reserve a part of length on the ground, and in each jack 3 is set on the supporting pile 2, all jack 3 all are in elongation state, and then on jack 3, make up caisson structure 4, the shoveling of can in open caisson, constructing after caisson structure 4 makes up and finishes.
In the present invention, for the convenience of describing, jack on the interior supporting pile 3 is divided into two batches, with its difference first jack of called after and second batch of jack, as for which first jack of jack called after, which jack called after is second batch of jack, and it is different and divide to look concrete construction environment.But, when dividing, can not divide arbitrarily, guarantee caisson structure 4 when first jack is removed, the second batch of jack be supporting caisson structure 4 with security and stability.Equally, when second batch of jack was removed, first jack is supporting caisson structure 4 with security and stability also.
When needing after waiting to construct to a certain degree for the first time to sink caisson structure, operate the stroke height that whole jack shortens a setting simultaneously, caisson structure 4 has just been realized sinking for the first time.
When needing after waiting to construct to a certain degree for the second time to sink caisson structure, at first shorten first jack disengaging load and displacement and abdicate the space, from the interior supporting pile corresponding 2 dismountings one joint stake joint 21, can adopt the box spanner dismounting during dismounting with first jack; Again first jack is installed on the interior supporting pile 2 and keeps first jack to keep elongation to hold out against and accept load.Make second batch of jack shorten the disengaging load and be shifted again and abdicate the space, from the interior supporting pile corresponding 2 dismountings one joint stake joint 21, in again second batch of jack being installed on the supporting pile 2 and keep second batch of jack to keep elongation to hold out against accepting load with the second batch of jack.Whole jack all was in to extend and held out against state this moment, operated the stroke height that whole jack shortens a setting simultaneously, and open caisson 4 has just been realized sinking for the second time.
So cycling can sink to the predetermined degree of depth with caisson structure 4.In order in caisson structure sinking process, can effectively to control the each distance of sinking of caisson structure to make things convenient for the construction under the caisson structure, preferably above-mentioned stake joint 21 is made into the stake joint of equal in length, so just guarantee that the distance of the each sinking of caisson structure is identical.
During above-mentioned construction, the process of dismounting stake joint 21 is compared the existing concrete pile that blocks, and its operating process is very quick, has shortened the construction period greatly.And the stake recyclable profit of joint under the dismounting also can be had enough to meet the need use in other object of construction production, compare the reinforced concrete pile that blocks and go out of use, and supporting pile has reduced the wasting of resources in the present invention.Technique scheme is particularly useful for the more shallow geological conditions of bearing course at pile end.
Fig. 5 and the structural representation that Figure 6 shows that the another kind of preferred implementation of supporting pile in the present invention, in the present embodiment, stake joint 21 comprises steel pipe 211, is installed in second flange 42 that has internal thread that steel pipe one end has first flange 41 of flange 411 and is installed in the steel pipe other end, described flange 411 is provided with external screw thread, and the first adjacent flange 41 cooperates so that stake joint 21 is installed together with the mode of second flange 42 by screw thread.Comparing stake joint structure recited above needs to install a plurality of bolts when mounted, and the stake joint installation and removal in the present embodiment are more quick, only needs to use the roll grip pipe wrench dismounting to get final product, and helps more shortening the engineering time., this thread connecting mode is specially adapted to the compound pile of circular cross-section but not fitting into the square-section.
Yet in some soil environment, for example in the weak soil layer in area, Nansha, Guangzhou, because the creep properties of weak soil can not steady in a long-termly effectively support the caisson structure that sinking puts in place, therefore the not all stake joint of supporting pile can both be recycled in above-mentioned, in order to guarantee the long-term safety stability of caisson structure, interior supporting pile 2 is generally squeezed into the ground degree of depth up to contacting with geology ground bearing stratum, after caisson structure sinks to putting in place, stake festival-gathering between caisson structure precalculated position and geology ground bearing stratum is used for supporting caisson structure by nonvolatil staying in weak soil, this nonvolatil interior supporting pile of general title is a foundation pile 25, as shown in Figure 7.Simultaneously, after caisson structure sinks to the precalculated position, concrete bearing platform 6 can also be set between interior supporting pile and caisson structure, cushion cap 6 links together caisson structure 4 with foundation pile is permanent.Make foundation pile can bear vertical downward pressure or the pull out force that makes progress.
Owing to need to reserve in one section supporting pile supporting caisson structure permanently after caisson structure sinks to putting in place in weak soil construction, as shown in Figure 8, the interior supporting pile 2 of another structure is provided again among the present invention, and it specifically comprises foundation pile 25 that is made of PHC pile tube (prestressed high-strength concrete pile) and the compound pile 20 that adopts dismountable mounting means to form by plurality of sections stake joint 21; Wherein, supporting pile 2 in above-mentioned foundation pile 25 and compound pile 20 are fixed together and constitute.Foundation pile 25 is prefabricated PHC pile tube or reinforced concrete pile or steel pipe pile, and the length of foundation pile 25 is generally determined by designing institute by various parameters.Certainly when prefabricated PHC pile tube, must simultaneously prefabricatedly in the top can the structure that cooperate be installed, will be shaped on sharp 31 a sinking in advance with supporting pile in helping 2 in its lower end with compound pile 20.The using method of interior supporting pile 2 in open caisson construction of this structure is substantially the same with the using method of the interior supporting pile that is combined by the stake joint fully, repeats no more here.After treating that caisson structure sinks to the precalculated position, directly on foundation pile top, build concrete bearing platform to be connected caisson structure and foundation pile are nonvolatil.Make foundation pile can bear vertical downward pressure or the pull out force that makes progress.This technical scheme is particularly useful for the darker geological conditions of bearing course at pile end.
Be illustrated in figure 8 as the structural representation of the third preferred implementation of above-mentioned interior supporting pile, its underpart is a foundation pile 25, upper end at foundation pile 25 is shaped on metal foil 251 in advance, fixedlying connected by the mode of welding bottom of metal foil 251 and compound pile 20, and with the stake joint 21 of the lowermost end of foundation pile 25 welding in be provided with stress diffusion rib 252 with diffusion-induced stress and reduce stress intensity.The lower end of foundation pile 25 is a stake point 31.Certainly, foundation pile 25 is not limited to being connected of welding manner with the mounting means of compound pile 20, also can adopt other mode to connect, for example: the time with concrete prefabricated foundation pile, can be embedded with bolt in the top in advance or have the flange of nut, the flange for the treatment of bolt after the concrete setting or having a nut also is fixed thereon end, and foundation pile and compound pile just can be installed together by dismountable mode like this, so just can be with the dismounting of the joint of all piles on the foundation pile down.And the stake joint structure of compound pile can adopt the structure of the interior supporting pile of Fig. 2 or Fig. 5, repeats no more here.
Here need to prove, because the complexity and the non-horizontality of foundation pile bearing stratum of geotechnical engineering, the error that when engineering construction, inevitably has construction and design during the submergence depth of supporting pile, be after supporting pile sinks, the top absolute altitude of foundation pile may be higher than design elevation (being superelevation), also may be lower than design elevation (promptly owing high).For the situation of the top absolute altitude superelevation of foundation pile, as long as along with the pile body of the sinking amputation superelevation constantly part of open caisson, because the distance of cutting not is very long, so can't produce too much influence to construction speed.For the pile body of owing high part, just do not remove remaining stake joint 21, as long as in stake joint 21, insert reinforcing bar, penetration concrete, form the concrete filled steel tube pile body, reach design elevation and get final product, owing to be that error of calculation causes, this segment distance generally can be not oversize, and generally 1 to 2 joint stake joint gets final product compensating error.
Above disclosed only is the preferred embodiments of the present invention, can not limit the present invention's interest field certainly with this, and therefore the equivalent variations of being done according to the present patent application claim still belongs to the scope that the present invention is contained.
