The utility model content
The utility model is at the defective of prior art existence, main purpose provides a kind of bound edge sawtooth pattern stake point, it has stronger penetration power, can press (beating) to wear very thick layer of sand and little soil (rock) layer of compressibilty, make the stake point reach desirable bearing stratum smoothly, reduce the damage of work progress simultaneously pile body.
For achieving the above object, the utility model adopts following technical scheme:
A kind of bound edge sawtooth pattern stake point, comprise the sharp base plate of stake, the rim of this base plate is provided with binding structure, convexes with plural piece gusset on the base plate front end face, this plural number piece gusset all around the middle mind-set of base plate radiation extend, and this gusset top end face is provided with the ladder sawtooth that sinks successively towards its bearing of trend.
Described bound edge and base plate are conjoined structure.
Described bound edge extends towards the rear end face of base plate, and is formed with the ccontaining recess that is used for ccontaining pile body.
The horizontal external diameter of described bound edge is greater than the tubular pile body external diameter.
Described gusset is the 4-6 piece.
The utility model is compared with technology with existing, its beneficial effect is, by sawtooth pattern stake point in conjunction with binding structure, because bound edge stake point diameter is bigger than pile tube, binding structure has enlarged the aperture of burying of pile tube, utilize the ageing of time difference of exist to shrink recovering in pile tube and the soil (rock) simultaneously, effectively reduce the moment frictional force between pile tube and soil (rock), thereby strengthen the penetration capacity of stake point, can press (beating) to wear very thick layer of sand and little soil (rock) layer of compressibilty thereupon, reduce the piling energy consumption, improve efficiency of construction, make the stake point can arrive desirable bearing stratum smoothly, reduce in the work progress damage simultaneously pile body, also can effectively reduce the vibrations in a machine and place, when reduce pressing (beating) during stake to the influence of other buildings and urban operating mechanism.When especially this bound edge sawtooth pattern stake point was applied to limestone area (karst area), the embedding rock ability that it can strengthen the stake point effectively reduced the breakage rate of playing (pressure) stake.
