Device for reducing pile sinking side friction resistance of PHC pipe pile
The invention discloses a device for reducing pile sinking side friction resistance of a PHC tubular pile, which comprises a tubular pile body, a first soil breaking ring, a second soil breaking ring, a plurality of soil breaking tips, a reinforcing ring, a resistance reducing device and a supporting ring, the first soil breaking ring is arranged at one end of the tubular pile body, and the multiple soil breaking tips are arranged on the first soil breaking ring; the multiple soil breaking tips are fixedly connected with a first soil breaking ring, a second soil breaking ring is arranged between the first soil breaking ring and the pipe pile body, a reinforcing plate is arranged between the second soil breaking ring and the first soil breaking ring, the front end of the reinforcing plate is also a soil breaking tip, and the size of the front end of the reinforcing plate is matched with that of the soil breaking tip. The size of the pipe pile body is matched with the size of the first soil breaking ring and the size of the second soil breaking ring. Through the first soil breaking ring and the second soil breaking ring, the soil breaking capacity of the pile head is greatly improved, through the vibration pile hammer, the pile sinking side friction resistance is greatly reduced, and the working efficiency is improved.
本发明公开了一种减少PHC管桩沉桩侧摩阻力的装置，包括管桩本体、第一破土圈、第二破土圈、破土尖端、加固圈、减阻装置以及支撑圈，所述管桩本体的一端设有第一破土圈，所述第一破土圈上设有多个破土尖端，多多个所述破土尖端与第一破土圈固定连接，所述第一破土圈与管桩本体之间设有第二破土圈，所述第二破土圈与第一破土圈之间设有加固板，所述加固板的前端也为破土尖端，且所述加固板前端的尺寸与破土尖端的尺寸相适配，所述管桩本体的尺寸与第一破土圈以及第二破土圈的尺寸相适配。本发明通过第一破土圈以及第二破土圈，大大增加桩头的破土能力，通过震动桩锤，极大减少了沉桩侧摩阻力，提高了工作效率。
