Reinforcing hoop prestress waste mud curing pile forming method
According to the method, a GURS-501 curing agent is added, and the GURS-501 curing agent has a good curing effect on slurry with the water content of 120%-160%, when the mixing amount of the curing agent is 2%, the strength of the curing agent is increased along with the age, when the mixing amount of the curing agent is 3%-4%, the strength of the curing agent is obviously increased, and when the mixing amount of the curing agent reaches 5%-7%, the strength of the curing agent is obviously increased along with the age. The 28d unconfined compressive strength of the solidified soil reaches 0.25-0.45 MPa and reaches the strength of the compacted engineering soil, so that the bonding effect of the processed pile body is guaranteed, meanwhile, the steel hoop is added, and the steel hoop is transversely added, so that the pile body has the advantages of effectively delaying crack development, improving the anti-seismic property of a component and improving the construction quality. And the shear bearing capacity, the axial pressure bearing capacity and the deformation capacity of the component are improved, so that the service life and the strength of the processed pile body are guaranteed.
本发明公开了一种筋箍预应力废弃泥固化成桩方法，通过添加GURS‑501固化剂，且由于GURS‑501固化剂对含水率120%‑160%的泥浆具有很好的固化效果，当固化剂掺量为2%时，其强度随着龄期的增长幅度相对较低，当掺量为3%‑4%时，其强度增长明显，当掺量达5%‑7%时，固化土28d无侧限抗压强度达0.25‑0.45MPa，达到压实后工程土的强度，从而保障了桩体加工完毕后的粘合效果，同时由于添加了钢套箍，且钢套箍的加入方式采用横向添加的方式，使得桩体具有效延缓裂缝开展，改善构件抗震性能，提高构件抗剪承载力、轴压承载力和变形能力，从而对桩体加工后的使用寿命以及强度起到了保障的作用。
