Stiff carrier pile and construction process
The invention discloses a stiff carrier pile, and belongs to the technical field of carrier piles. The stiff carrier pile comprises an outer pile body, an inner pile core, a carrier filler and a carrier expansion head, the inner pile core is arranged on the inner side of the outer pile body, and the carrier expansion head is arranged at the bottom end of the outer pile body. The invention further discloses a construction process of the stiff carrier pile. According to the stiff carrier pile and construction process, steel slag or steel slag powder-doped dry hard concrete is used as filler, so that the environment-friendly pressure of zero emission of the steel slag in a steel plant can be solved, wastes can be utilized, and resources can be saved, when the steel slag or the steel slag powder-doped dry hard concrete is used as the filler, a carrier is formed in a soil layer or a saturated soil layer with relatively high water content, water in surrounding soil can be adsorbed to the carrier until hydration balance is achieved, the strength of the carrier can be improved through the hydration reaction, the quality is stable and reliable, the micro-expansibility and the water sealing effect of the steel slag or the steel slag powder-doped hard concrete are good, and underwater construction of the carrier is facilitated.
本发明公开了一种劲性载体桩，属于载体桩技术领域，包括外桩身、内桩芯、载体填充料和载体扩大头，所述外桩身的内侧设置有内桩芯，所述外桩身的底端设置有载体扩大头；本发明还公开了一种劲性载体桩的施工工艺；本发明将钢渣或掺钢渣粉干硬性混凝土作为填充料，可以帮助钢铁厂解决钢渣“零排放”的环保压力，废物利用，节省资源，本发明将钢渣或掺钢渣粉干硬性混凝土作为填充料，在含水量较大的土层或饱和土层中形成载体时，可使周围土体中的水分被吸附到载体上来，直到达到水化平衡为止，水化反应的可使载体强度得到提高，质量稳定可靠，而且钢渣或掺钢渣粉干硬性混凝土的微膨胀性、封水效果好，有利于载体的水下施工。
