Abstract
The utility model relates to an anchor rod static pressure anti-pulling steel pipe pile with a lower portion grouted. The anchor rod static pressure anti-pulling steel pipe pile comprises a pile body and a pile end, wherein the pile end is sealed, an annular steel plate is welded on the inner side of a lower portion of the pile body, a circle of rebar is welded on the outer side of the lower portion of the pile body, a hole is reserved in the middle of the annular steel plate, grouting holes are reserved on the pile wall down from the annular steel plate, and iron barbs are arranged on the grouting holes. Since the pile end is sealed, the grouting holes are reserved on the pile body, and the iron barbs are arranged, the grouting holes can be prevented from being blocked by surrounding particles. An expansion head can be formed by grouting the pile body, and anti-pulling bearing capability of a single pile can be effectively improved. The anchor rod static pressure anti-pulling steel pipe pile has the advantages that construction is facilitated, strength of the pile body can be effectively developed, the anti-pulling bearing capability of the single pile is high, and the like.
Description
Technical field
The utility model relates to a kind of bottom grouted anchor bar static pressure resistance to plucking steel pipe pile, is mainly used in the existing building underpin, solves building anti-floating problem.
Background technology
The building basement uplift pile was lost efficacy or was designed the effect of not considering buoyancy force of underground water fully, and much the situation of the suffered water buoyancy of basement greater than dead load appearred in engineerings, showed as the whole floating of basement, had a strong impact on building safety and normally use.Occur to take effective underpin measure after the problems referred to above, solve basement anti-floating problem by resetting uplift pile, the general mode of anchor jacked pile that adopts is reinforced, but conventional anchor rod static pressure pile anti-pulling capacity is limited, piling quantity can be many, construction costs is high on the one hand, in addition piling perforate on base plate, the number of openings is more, globality and bending resistance impact on basement bottom board are larger, and the construction technology that therefore improves uplift bearing capacity, easy construction remains to be proposed.
The utility model content
But the purpose of this utility model provides the stake bottom grouted anchor bar static pressure resistance to plucking steel pipe pile of a kind of Effective Raise uplift bearing capacity and easy construction.
The purpose of this utility model is achieved in that
A kind of bottom grouted anchor bar static pressure resistance to plucking steel pipe pile, comprise pile body and stake end, described stake end place's sealing, in the bottom of described pile body, the inboard welding of described pile body doughnut-shaped steel plate, outside welding one circle reinforcing bar, the centre of described doughnut-shaped steel plate is a hole, from doughnut-shaped steel plate down, have injected hole at the pile body wall, the angle bar hangnail is set on the described injected hole.
Wherein, described pile body is formed by some joint steel-pipe weldings, and two joint steel pipes weld together by outer steel pipe up and down; Described doughnut-shaped steel plate is arranged on 1.5m place, described stake end top; Described reinforcing bar is arranged on 1.5m place, described stake end top.
Further, described injected hole quantity is six, is respectively arranged with the angle bar hangnail on each injected hole.
The utility model is owing to having adopted technique scheme, compared with prior art have following beneficial effect: a kind of bottom of the utility model grouted anchor bar static pressure resistance to plucking steel pipe pile designs injected hole by the stake end of sealing and at pile body, and the angle bar hangnail is set prevents that injected hole is by surrounding environment Particle Blocking injected hole.By slip casting in pile body, thereby form enlarged footing, but Effective Raise single pile resistance to plucking supporting capacity has easy construction, can effectively bring into play pile strength and uplift bearing capacity high.
Description of drawings
By following embodiments of the invention and description taken together with the accompanying drawings, other advantage of the present invention and feature are shown, this embodiment provides with the form of example, but is not limited to this, wherein:
Fig. 1 is the structural representation of an embodiment of a kind of bottom of the utility model grouted anchor bar static pressure resistance to plucking steel pipe pile;
Fig. 2 is the pile body syndeton schematic diagram of embodiment shown in Fig. 1;
Fig. 3 be a kind of bottom of the utility model grouted anchor bar static pressure resistance to plucking steel pipe pile carry out slip casting the time the work schematic diagram;
Fig. 4 is the effect schematic diagram after a kind of bottom of the utility model grouted anchor bar static pressure resistance to plucking steel pipe pile is finished slip casting.
The specific embodiment
As shown in Figure 1, a kind of bottom grouted anchor bar static pressure resistance to plucking steel pipe pile comprises pile body 1 and stake end 2, the 2 places sealing of stake end, in the bottom of pile body 1, in the present embodiment, for stake end 2 at a distance of the 1.5m place, pile body 1 inboard welding doughnut-shaped steel plate 3, outside welding one circle reinforcing bar 4, the centre of doughnut-shaped steel plate 3 is a hole 31, from doughnut-shaped steel plate 3 down, have six injected holes 5 at pile body 1 wall, angle bar hangnail 6 is set respectively on the injected hole 5.In conjunction with shown in Figure 2, pile body 1 is formed by some joint steel-pipe weldings, and two joint steel pipes weld together by outer steel pipe 7 up and down.
As shown in Figure 3, during work, utilize the anchor rod static pressure steelframe section by section steel pipe pile to be pressed into projected depth, adopt outer steel pipe 7 to be welded to connect when steel pipe pile section and the joint.After putting in place, piling carries out pile end grouting: lower Grouting Pipe 8 in steel pipe pile, Grouting Pipe 8 just in time is stuck in the hole 31, slip casting in the 1.5m scope on 2 is held in slip casting to stake, thereby forms enlarged footing 9(as shown in Figure 4 in the steel pipe pile bottom), but Effective Raise single pile resistance to plucking supporting capacity.
Although the utility model is illustrated hereinbefore according to preferred embodiment of the present utility model; but this does not represent that scope of the present utility model is confined to above-mentioned structure, if by structure that claim of the present utility model covered all within protection domain.Those skilled in the art are reading the equivalent substitution structure that can develop at an easy rate after the above-mentioned explanation, and these equivalent alternative structure also are within the scope that this case requires.
