Abstract
The invention discloses a strengthened pile. A core pipe is arranged in a pile body in along the pile length. The core pipe is diverged every other a certain distance. Outlets are formed in the surrounding surface of the pile body. Bearing connectors are arranged at the upper connecting end and the lower connecting end of the pile length, and the core pipe in the pile is communicated with the outlets in the surface of the pile body. After the pile is pressed in a foundation, the high-strength material is pressed into the core pipe, flows out of the outlets in the surface of the pile body through diverging and seeps into a surrounding soil layer of the pile, accordingly, the strength of the surrounding soil body of the pile body is improved, and the bearing force or pulling resisting force of the pile can be improved.
Description
Technical field
The present invention relates to a kind of preformed pile, particularly can improve the carrying of stake or the enhancing stake of breakout capacity.
Background technology
Current, known preformed pile, has square pile, pipe (circle) stake etc., is cylinder or barrel type, pile body surface smoothing.Pile body is at press-in foundation bearing building or stop building sink-float, and pile body moves downward or upward, and the soil body, to the pressure beam power of pile body, stops pile body to move downward or upward, namely produces the friction bearing capacity of stake.Crude or smoothly relevant due to frictional force mainly with area of friction surface and rubbing surface, relevant with rubbing contact-material intensity, stake surface smoothing frictional force is little; The soil strength contacted with stake is low, and pile capacity is just little, is unfavorable for that the effect of stake plays.
Summary of the invention
The object of the invention is to provide a kind of and strengthen stake, it under the condition that stake surface area is constant, changes the intensity contacting the soil body with pile body, namely increases the friction ratio of pile body and the soil body after press-in ground.Reach and improve the bearing capacity of stake or the object of uplift resistance.
The object of the present invention is achieved like this: in preformed pile pile body, arrange core pipe along stake is long, and diverged by core pipe at interval of certain distance, arranges outlet, an inner core tube is communicated with pile body Skin Exit in pile body circumferential surface; For smooth pile extension, at the long upper and lower link of stake, core pipe arranges undertaking interface.After stake press-in ground, Materials with High Strength is pressed into core pipe, by pile body Skin Exit, around Materials with High Strength infiltration stake in soil layer, improve pile body surrounding soil intensity, namely improve the frictional resistance of the soil body to stake, the bearing capacity of stake or uplift resistance are improved.
The present invention is because the outlet on pile body surface, and being be arranged symmetrically with pile body central axis, is at a certain distance, and the layout a pair that rotates to an angle, make the soil strength of a periphery reach even, be conducive to the raising of an intensity and supporting capacity.
Accompanying drawing explanation
Fig. 1 strengthens stake longitudinal plan, comprises core pipe (1), fork (2), outlet (3), interface (4).
Detailed description of the invention
Strengthening stake is a kind of preformed pile, in pile body, core pipe (1) is set along stake is long man-hour adding, and at interval of certain distance by core pipe fork (2), after core pipe fork, be arranged symmetrically with outlet (3) along pile center, an inner core tube is communicated with pile body Skin Exit; At the long upper and lower link of stake, core pipe (1) is arranged accepts interface (4).Stake is prefabricated reaches intensity, needs pile extension during press-in ground, for making an inner core tube communicate, with the special grafting of inserting interface, upper and lower stake core pipe being connected and communicates.After reinforcing pile enters ground, by Materials with High Strength high-pressure pump press-in core pipe, by pile body Skin Exit, around infiltration stake in soil layer, soil strength around enhancing stake is improved, namely improves the frictional resistance of the soil body to stake, the bearing capacity of stake or uplift resistance are improved.
The outlet on pile body surface of the present invention, be be arranged symmetrically with pile body central axis, be advisable with 2 ~ 4 meters along the long spacing distance of stake, be arranged as suitable along the stake ambient separation anglec of rotation with 30 ° ~ 45 °, make the soil strength of a periphery reach even, be conducive to the raising of an intensity and supporting capacity.
