Fig. 1 is the structural representation of static pressed pile counterforce device in prior art；
Fig. 2 is the perspective view of this utility model anchor jacked pile counterforce device.
In accompanying drawing, the labelling of each parts is as follows: 1, column support, and 2, upper plate, 3, lower shoe, 4, through hole, 5, jack, 6, screw-thread steel, 7, screens nut, 8, cover plate, 9, prefabricated pile.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 2, this utility model embodiment includes:
A kind of anchor jacked pile counterforce device, it is mainly used in construction of Static Pressure Pile in existing basement, including: it is arranged in both sides, piling hole and symmetrically arranged two counter-force supports, described counter-force support includes two column supports being fixed on basement bottom board 1 and the upper plate 2 being fixed between two column support 1 upper ends, concrete, bottom described column support 1 and anchor connection between basement bottom board, stable connection, concrete anchorage style is prior art, is the most no longer described in detail.
This counterforce device also includes the lower shoe 3 between two counter-force supports, there is in the middle part of described lower shoe 3 one and typically use pre-manufactured steel pile tube for prefabricated pile 9() through hole 4 that passes, a jack 5 respectively it is fixed with on the lower shoe of described through hole 4 both sides, the upper end of described jack 5 is fixed on upper plate 2, concrete, together with described jack upper end is bolted with upper plate, together with described jack lower end is bolted with lower shoe, owing to upper plate position is fixed, lower shoe can be driven to rise or fall when starting jack.
It is additionally provided with, on lower shoe around described through hole 4, the through hole that at least two is parallel with through hole axis, described through hole is equipped with screw-thread steel 6, preferably fining twisted steel, being positioned on described screw-thread steel 6 at the top and bottom of lower shoe respectively carries out spacing by a screens nut 7, thus fixes screw-thread steel；A cover plate 8 it is placed with on the end face of described prefabricated pile 9, described screw-thread steel passes this cover plate 8, and be positioned on screw-thread steel at the upper surface of cover plate and carry out spacing by a screens nut, said structure makes when lower shoe declines, cover plate can be driven to move downward, thus prefabricated pile is pressed downward against, it is achieved piling purpose.
Having a groove (not shown) matched with prefabricated pile top with prefabricated pile on the face that described cover plate 8 contacts, during piling, prefabricated pile top is positioned in described groove so that piling process is more stable, improves piling efficiency and quality.
This utility model additionally provides the construction method of above-mentioned anchor jacked pile counterforce device, including step in detail below:
A, according to the selected good piling hole site of design, and dig out the piling hole of certain depth；
B, counter-force support is installed on the basement bottom board of both sides, piling hole, and has been respectively mounted lower shoe, jack and screw-thread steel；
C, being hung by prefabricated pile in piling hole, prefabricated pile passes lower shoe；
D, install cover plate at prefabricated pile top；
E, startup jack, jack drives lower shoe to move downward, and lower shoe drives cover plate to move downward by screw-thread steel, thus drives prefabricated pile to move downward, it is achieved piling；
F, treat that prefabricated pile is pressed onto projected depth, unload lower cover, hang another root prefabricated pile and splice with previous prefabricated pile, then install cover plate and continue piling, so repeat until prefabricated pile total depth reaches design load.
In method of the present utility model when hanging prefabricated pile, it is specifically divided into following two situation, when through hole at a distance of through hole farther out time, the most adjacent space between two screw-thread steels is relatively big, and enough prefabricated piles pass through, then have only to get off detachable cover plate, can hang, this method tears screw-thread steel open owing to need not, and facilitates comparatively speaking, but during piling, stability is slightly worse；
When through hole is when through hole is nearer, and the most adjacent space between two screw-thread steels is less, is insufficient to prefabricated pile and passes through, then needing to disassemble cover plate together with screw-thread steel, can hang, this method tears screw-thread steel open due to needs, bother comparatively speaking, but during piling, stability is preferable.
The beneficial effects of the utility model are: this utility model anchor jacked pile counterforce device, simple and reasonable, have safe and reliable, economical rationality, the advantage of easy construction, it is possible to effectively save the duration, and little on surrounding enviroment impact.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in scope of patent protection of the present utility model.
