Pile foundation equipment capable of dealing with variable loads of foundation
The invention the technical field of pile foundations and discloses pile foundation equipment capable of dealing with variable loads of a foundation. The pile foundation equipment comprises a pile body. Rotary shaft are movably connected to the interior of the pile body. The surface of the pile body are connected with drill pipes. Wrapping posts are movably connected to the interiors of the drillpipes. The bottoms of the wrapping posts are movably connected with spring rods. The two sides of each wrapping post are movably connected with a load-bearing plate. The internal sidewalls of the load-bearing plates are provided with sliding grooves. The surfaces of the sliding grooves are slidably connected with flexible balls. The rotary shafts are manually rotated to tension pull cords, so thatvolute spiral springs are triggered to push out the symmetric load-bearing plates. Meanwhile, the flexible balls are pushed out of the load-bearing plates from the sliding grooves, the contact area of the load-bearing plates with the soil is increased. Moreover, when the drill pipes move downwards to encounter with a rock layer, the resistance of the lower ends of the drill pipes is increased. Therefore, when the drill pipes go deep into the rock layer, support legs extend out continuously, so that the effects of increasing the transverse load of the pile foundation and reducing the resistance during pile driving are achieved.
本发明涉及桩基础技术领域，且公开了一种可应对地基变载荷的桩基础设备，包括桩体，所述桩体的内部活动连接有转轴，转轴的表面连接有钻杆，钻杆的内部活动连接有绕线柱，绕线柱的底部活动连接有弹簧杆，所述绕线柱的两侧均活动连接有载荷板，载荷板的内部侧壁开设有滑槽，滑槽的表面滑动连接有伸缩球。通过人为转动转轴收紧拉绳，故涡卷弹簧被触发而将对称的载荷板推出，且与此同时，伸缩球从滑槽被推出载荷板表面，增加载荷板与土壤的接触面积，且在钻杆向下移动的同时，当钻杆遇到岩石层时，钻杆下端的阻力变大，故随着钻杆深入岩石层内部支脚也不断伸出，从而达到了增加桩基础横向载荷且减少打桩时的阻力的效果。
