Abstract

The utility model discloses a kind of concrete floral tube slip casting uplift pile, its concrete pile is the concrete pipe (1) that inner sleeve has reinforcing cage (2), has plural injected hole (3) on its tube wall; The interior diameter of described concrete pipe (1) is that 25~45cm, wall thickness are 3~4cm, described injected hole (3) in concrete pipe (1) spacing on be axially 8~12cm, apart from concrete pipe (1) two ends all >=1.5m, number≤3 of described injected hole (3) on the same cross section of concrete pipe (1), described injected hole (3) is rectangle, and described injected hole (3) is circular.It by injecting pea gravel concreten mud jacking in concrete pipe (1), form the uplift pile with cross rib (5), greatly increased contact area, there is extremely strong extraction-resistant behavior, add the humidification of reinforcing cage, firmer, durable; Can be widely used in the resistance to plucking in construction project field.

Description

Concrete floral tube slip casting uplift pile
Technical field
The utility model belongs to pile foundation engineering field, is specifically related to a kind of concrete floral tube slip casting uplift pile.
Background technology
Along with the fast development of China's urban construction, the exploitation of the underground space is more and more paid attention to, and has brought many new technical problems also to the design of engineering, construction simultaneously, and wherein, basement anti-floating problem is particularly outstanding.Due to the effect of buoyancy force of underground water, basement bottom board can produce protuberance in various degree, when serious, also can cause the inhomogeneous floating of building, affects the normal use of building.
The Anti-floating design of existing engineering mainly comprises anchor slab lex fundamentalis, increases the methods such as deadweight and uplift pile, and wherein uplift pile is due to high, the easy construction of stability, applied widely being widely used.
For the resistance to plucking of stake, mainly there is at present following problem: the one, the extraction-resistant behavior of all kinds of stakes is widely different, and particularly CFG stake, does not possess resistance to plucking ability substantially, can not be used as uplift pile; The 2nd, the uplift resistance of each type is often much smaller than vertical limit bearing capacity, can not give full play to the performance of stake.Therefore, the extraction-resistant behavior of raising stake is the important topic of current pile foundation engineering area research.
Utility model content
The technical problems to be solved in the utility model, for overcoming weak point of the prior art, provides a kind of rational in infrastructure, the concrete floral tube slip casting uplift pile that uplift resistance is strong.
For solving technical problem of the present utility model, the technical scheme adopting is: concrete floral tube slip casting uplift pile comprises concrete pile, particularly,
Described concrete pile is concrete pipe, and described concrete pipe inner sleeve has reinforcing cage;
On the tube wall of the concrete pipe of described inner sleeve reinforcing cage, have plural injected hole.
Further improvement as concrete floral tube slip casting uplift pile:
Preferably, the interior diameter of concrete pipe is that 25~45cm, wall thickness are 3~4cm.
Preferably, injected hole in concrete circular tubular axis spacing be upwards 8~12cm, apart from concrete pipe two ends all >=1.5m.
Preferably, number≤3 of injected hole on the same cross section of concrete pipe.
Preferably, injected hole is rectangle.
Preferably, injected hole is circular.
Beneficial effect with respect to prior art is:
One, when concrete pipe lifts to projected depth, in concrete pipe, pour into pea gravel concreten, and by mud jacking by pea gravel concreten in the soil body of injected hole pressure pile end and sidewall, be cemented to entirety with the soil body, formed the uplift pile with cross rib, greatly increased the contact area of pile body and the soil body, thereby make it have extremely strong extraction-resistant behavior, be specially adapted to recent deposit soil and plain fill.
Its two, rational in infrastructure, uplift resistance is strong, pile mode is simple, practical.
Brief description of the drawings
Fig. 1 is a kind of basic structure schematic diagram of the present utility model.
Fig. 2 is a kind of basic structure schematic diagram of the injected hole in the utility model while being rectangle.
Fig. 3 is a kind of basic structure schematic diagram of the injected hole in the utility model while being circle.
Fig. 4 is a kind of view that uses of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, optimal way of the present utility model is described in further detail.
Referring to Fig. 1, Fig. 2 and Fig. 3, being constructed as follows of concrete floral tube slip casting uplift pile:
Concrete pipe 1 inner sleeve as concrete pile has reinforcing cage 2, has 22 injected holes 3 on tube wall; Wherein, the interior diameter of concrete pipe 1 is that 30cm, wall thickness are 3cm, injected hole 3 in concrete pipe 1 spacing on be axially 10cm, apart from concrete pipe 1 two ends all >=1.5m, the number of injected hole 3 on the same cross section of concrete pipe 1 is 3, the rectangle (or being the circle of diameter 3cm) that injected hole 3 is 3 × 5cm.
When use, first utilize long-spiral drilling machine pore-forming, then the concrete pipe 1 in the utility model is lifted to projected depth, again to the interior perfusion pea gravel concreten 4 of concrete pipe 1, and by mud jacking, the pea gravel concreten 4 in concrete pipe 1 is clamp-oned in the soil outside pipe through injected hole 3, after mud jacking, insert immediately reinforcing cage 2, after concrete reaches design strength, form the very firmly uplift pile with cross rib 5 as shown in Figure 4.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model concrete floral tube slip casting uplift pile of the present utility model.Like this, if to these amendments of the present utility model with within modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these changes and modification interior.
