Abstract
The utility model relates to a pipe pile with the pre-locating function and belongs to the technical field of building construction. The pipe pile with the pre-locating function comprises a tubular pile body. A horizontal pile sealing plate is fixed to the lower end of the pile body. A locating steel core extending downwards is fixed to the position, corresponding to the geometric center of the pile body, of the lower surface of the pile sealing plate. Steel plates which are distributed in a cross-shaped mode are fixed to the outer side of the upper portion of the locating steel core. The outer sides of the steel plates are inclined edges which gradually incline downwards, so that a steel plate pile toe is formed. When the pile is driven into earth, the locating steel core enters a bearing stratum before the steel plate pile toe is located so as to have the pre-locating function, the steel plate pile toe is guided to enter the bearing stratum, and therefore the pipe pile is accurately driven into a preset position. Due to the pre-locating function of the locating steel core, even if the pile toe encounters an inclined rock face, the pile toe can be effectively prevented from sliding, it is guaranteed that hammering is smoothly ended and the pipe pile is well constructed, and the situation that the pipe pile is broken or the pipe pile is damaged and scrapped is avoided.
Description
Technical field
The utility model relates to a kind of pile tube, and especially a kind of leading location pile tube, belongs to technical field of building construction.
Background technology
Applicant finds in building operations practice, at complicated geological conditions injection pile for prestressed pipe, if bearing stratum is inclination bedrock surface, adopt the location piling of common cross-shaped steel plate pile tip, while receiving hammer, easily there is the slippage of stake end, gently affect piling quality, heavy cause fracture accident.
Summary of the invention
The purpose of this utility model is: the problem running into for above-mentioned building operations, and by architecture advances, even if propose a kind of bearing stratum, run into inclination bedrock surface and also can avoid slippage, guarantee the accurately leading location pile tube of location.
In order to reach above object, leading location of the present utility model pile tube comprises tubulose pile body, the lower end fixed level envelope stake plate of described pile body, the fixing location steel core towards downward-extension in the corresponding pile body geometric center of described envelope stake plate soffit position; Described location steel core upper outside is fixedly the steel plate of crossing distribution, and the hypotenuse that the outside of described steel plate is downward gradually closing forms steel plate pile top.
During piling, location steel core was introduced in advance bearing stratum before steel plate pile top is in place, played the effect of leading location, and guiding steel plate pile top enters bearing stratum, and then makes pile tube accurately squeeze into precalculated position.Owing to there being the leading positioning action of location steel core, even thereby run into inclination scar, also can effectively avoid pile top slippage, guarantee that pile tube receives stake hammer out smoothly, stop broken pile or pile body and broken and cause useless stake.
Further, described envelope stake plate soffit is welded and fixed the location steel core towards downward-extension by the steel substrate being connected with it.
Further, the taper of downward gradually closing is made in the periphery of described steel substrate.
Further again, described location steel core reinforcement fabrication, its lower end metal pointing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the perspective view of Fig. 1 embodiment.
The specific embodiment
Embodiment mono-
The present embodiment is located pile tube as depicted in figs. 1 and 2 in advance, comprise columniform tubulose pile body 1, the lower end fixed level envelope stake plate 2 of this pile body 1, the corresponding pile body geometric center of these envelope stake plate 2 soffits---the position of cylindrical axis is welded and fixed the location steel core 3 towards downward-extension by the steel substrate 4 being connected with it, this location steel core 3 can be made of bar reinforcement, its lower end metal pointing.Location steel core 3 upper outside are welded and fixed the steel plate 5 that is crossing distribution, and the hypotenuse that the outside of steel plate 5 is downward gradually closing forms steel plate pile top.The taper of downward gradually closing is made in the periphery of steel substrate 4, can play transition guiding function to pile body like this, more smooth and easy during piling.
During construction, to on-the-spot geological condition supplementary investigation, find out the elevation of bearing stratum bedrock surface, adopt the pile tube of the present embodiment, when pile tube injection approaches bearing stratum, the location steel core of pile top is squeezed into rapidly bearing stratum, leading location, guiding taper steel sheet pile point enters strengthening wind basement rock bearing stratum, and the basement rock bearing stratum of effectively having avoided pile top to encounter inclined plane causes slippage broken pile cannot receive hammer, or pile top embedding ability is poor causes pile body to be battered down causing useless stake, construction quality and construction speed have been guaranteed.
