Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 2, the embodiment of the present invention comprises:
A kind of anchor jacked pile counterforce device, be mainly used in construction of Static Pressure Pile in existing basement, comprise: be arranged in both sides, piling hole and symmetrically arranged two counter-force supports, described counter-force support comprises two upper plates 2 being fixed on the column support 1 on basement bottom board and 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 no longer described in detail here.
This counterforce device also comprises the lower shoe 3 between two counter-force supports, there is in the middle part of described lower shoe 3 one and generally adopt pre-manufactured steel pile tube for preformed pile 9() through hole 4 that passes, the lower shoe of described through hole 4 both sides is respectively fixed with a jack 5, 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, because upper plate position is fixed, lower shoe can be driven when starting jack to rise or decline.
Lower shoe around described through hole 4 is also provided with at least two with the through hole of through hole axis being parallel, screw-thread steel 6 is equipped with in described through hole, preferred fining twisted steel, the top and bottom place described screw-thread steel 6 being positioned at lower shoe is respectively undertaken spacing by a screens nut 7, thus fixes screw-thread steel; The end face of described preformed pile 9 is placed with a cover plate 8, described screw-thread steel is through this cover plate 8, and upper surface place screw-thread steel being positioned at cover plate is undertaken spacing by a screens nut, said structure makes when lower shoe declines, cover plate can be driven to move downward, thus by preformed pile to pressing down, realize piling object.
The face that described cover plate 8 and preformed pile contact has a groove (not shown) matched with preformed pile top, during piling, preformed pile top is arranged in described groove, makes piling process more stable, improves piling efficiency and quality.
Present invention also offers the construction method of above-mentioned anchor jacked pile counterforce device, comprise following concrete steps:
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 installs lower shoe, jack and screw-thread steel respectively;
C, hang in piling hole by preformed pile, preformed pile is through lower shoe;
D, install cover plate at preformed 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 preformed pile to move downward, and realizes piling;
F, treat that preformed pile is pressed onto projected depth, unload lower cover, hang another root preformed pile and splice with last preformed pile, then install cover plate and continue piling, so repeat until preformed pile total depth reaches design load.
In method of the present invention when hanging preformed pile, specifically be divided into following two kinds of situations, when through hole is when through hole is far away, namely the space between two adjacent screw-thread steels is comparatively large, and enough preformed piles pass through, then only need detachable cover plate to get off, can hang, this method, owing to not needing to tear screw-thread steel open, facilitates comparatively speaking, but during piling, stability is slightly poor;
When through hole is when through hole is nearer, namely the space between two adjacent screw-thread steels is less, not enough preformed piles pass through, cover plate is then needed to disassemble 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 better.
The invention has the beneficial effects as follows: anchor jacked pile counterforce device of the present invention and construction method thereof, simple and reasonable, there is the advantage of safe and reliable, economical rationality, easy construction, effectively can save the duration, and little on surrounding enviroment impact.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
