Abstract
The utility model relates to a skewed tooth stake point tubular pile belongs to construction technical field. This tubular pile includes pipy steel pipe pile body, the fixed horizontally stake point base plate of front end of pile body, the fixed centering stake point in lower extreme center of the sharp base plate of stake, all corrals of the sharp base plate of stake have profile of tooth stake point, each prong of profile of tooth stake point is in the coplanar that becomes the inclination with stake point base plate, the size at inclination with wait to drive piles supporting course scar angle of inclination unanimity. Like this, when carrying out piling operations, profile of tooth stake point can be in the prelocalization of slope basement rock supporting course onlap profiling to it slides or the broken pile accident effectively to prevent the stake end.
Description
Technical field
The utility model relates to a pile tube, and especially a kind of helical teeth pile top pile tube, belongs to technical field of building construction.
Background technology
Piling is the crucial operation of building operation. As depicted in figs. 1 and 2, the steel pipe piling body of tubulose 2 times ends are welded and fixed pile top substrate 1 to the cross type pile toe steel pipe piling of prior art, and this plate lower surface dead center point 1-1, the cone back cover 1-2 of the side in cruciform is fixed in the periphery of middle apex of the heart 1-1. At the geologic condition injection steel pipe pile tube of complexity, when bearing stratum is for tilting bedrock surface, adopts conventional cross type pile toe steel pipe piling, when receiving hammer, end slippage or a fracture accident easily occur.
Summary of the invention
The purpose of this utility model is: for above-mentioned prior art Problems existing, by the improvement to pile top structure, it is proposed to a kind of can effectively avoiding is tilting the helical teeth pile top pile tube producing stake end slippage or fracture accident on bedrock surface in piling process.
In order to reach above object, helical teeth pile top pile tube of the present utility model comprises the steel pipe piling body of tubulose, the pile top substrate of the front end fixing horizontal of described stake body, the lower center of described pile top substrate fixing centering pile top, it is characterized in that: the border of described pile top substrate is with profile of tooth pile top, each crown of described profile of tooth pile top is in the same plane becoming inclination angle with pile top substrate, and the size at described inclination angle is consistent with treating piling bearing stratum oblique rock surface angle.
Like this, when carrying out piling work, profile of tooth pile top can be located in advance on inclination basement rock bearing stratum, thus effectively prevents end slippage or a fracture accident.
Further, the cross section of described centering pile top is cruciform.
Further again, described centering pile top is welded by two blocks of right-angle triangle centering muscle plates of the main centering plate of one piece of isosceles triangle and both sides.
Further again, the summit of described main centering plate lower than the sharp point of centering muscle plate, and higher than described plane.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the perspective view of prior art steel pipe piling.
Fig. 2 is the partial cutaway TV structure schematic diagram of Fig. 1.
Fig. 3 is the structural representation of the utility model embodiment.
Fig. 4 is the partial cutaway TV structure schematic diagram of Fig. 3.
Embodiment
Embodiment one
The helical teeth pile top pile tube of the present embodiment as shown in Figure 3 and Figure 4, the pile top substrate 1 of the front end fixing horizontal of tubular steel pile tube body 2. The centering pile top 1-1 in the lower center fixed cross shape cross section of pile top substrate 1, this centering pile top is welded by two pieces of right-angle triangle centering muscle plate 1-b of the main centering plate 1-a of one piece of isosceles triangle and both sides, and wherein the summit of main centering plate 1-a is lower than the sharp point of centering muscle plate 1-b. The border of pile top substrate 1 is with the profile of tooth pile top 1-3 of eight equal parts tooth by welding, and each crown of profile of tooth pile top 1-3 is in the same plane P becoming inclination angle A with pile top substrate, and the size of inclination angle A is consistent with treating piling bearing stratum scar 3 pitch angle. The summit of main centering plate 1-a is higher than plane P.
Due in advance to construction field geology situation supplementary investigation, elevation and the vergence direction of bearing stratum bedrock surface are found out, the corresponding pile top structure reforming out the present embodiment, when carrying out piling work, eight equal parts profile of tooth pile top squeezes into bearing stratum in pile tube injection to moving ahead during bearing stratum, advanced location, therefore effectively prevent slippage broken pile when centering pile top encounters scarp basement rock bearing stratum and cannot receive hammer, or pile top embedding ability difference causes the body to be beaten the rotten phenomenon causing useless stake, Reliable guarantee construction quality.
In addition to the implementation, the utility model can also have other enforcement modes. Such as, profile of tooth pile top number change, or non-decile arranges. All employings are equal to replacement or the technical scheme of equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (4)
