High-resistance hammering pile sinking system
The invention discloses a high-resistance hammering pile sinking system. The high-resistance hammering pile sinking system comprises a pile body with the conical bottom, a middle pipe is arranged in the pile body, an upper pipe communicates with the upper end of the middle pipe, the upper pipe communicates with the outside, a lower ball communicates with the lower end of the middle pipe, and the lower ball is located at the bottom of the pile body; and the pile body is wrapped with a layer of metal net, a plurality of side pipes are embedded in the position, close to the outer wall, of the pile body, a plurality of side holes are formed in the upper sides of the side pipes in a lateral communication mode and communicate with the outside, and the gap between the metal net and the outer wallof the pile body is 1-3 mm. The high-resistance hammering pile sinking system has the advantages that the middle pipe is filled with water, a large amount of heat generated by friction of the outer wall of the pile body can be absorbed, when the pile cone impacts the pile body, the water in the middle pipe can move into an external water tank through the upper pipe, the heat-absorbed water can beexchanged with the outside, obvious temperature rise of the pile body is avoided, and the pile body is prevented from generating gaps with soil to reduce resistance.
本发明公开了一种高阻力锤击沉桩系统，包括底部设置成锥状的桩体，所述桩体内开设有中管，所述中管的上端连通有上管，所述上管与外界连通，所述中管的下端连通有下球，所述下球位于桩体的底部；所述桩体外包裹有一层金属网，所述桩体靠近外壁处埋设有多根边管，所述边管上侧向连通有多个边孔，所述边孔与外界连通，所述金属网与桩体外壁的间隙为1～3mm。优点在于：中管内灌有水，可大量吸收桩体外壁摩擦产生的热量，且桩锥撞击桩体时，中管内水会经上管运动至外界的水箱中，可将吸收热量的水与外界进行交换，避免桩体温度明显升高，避免桩体因温度升高导致其与土壤产生缝隙降低阻力。
