The invention discloses a method for improving the strength of a cement mixing pile in a sludge area. According to the method, a group of compressive strength formulas is put forward, so that the sandmixing proportion is obtained through calculation so as to finish construction of the cement mixing pile. The invention further discloses a sand mixing device. The sand mixing device can reasonably and effectively finish construction of the mixing pile by combining the calculation result. According to the method, sand with a proper proportion can be mixed on the premise of not adding the cement content and the maintenance period, so that the strength of the cement mixing pile in the sludge area is improved, the cheap and environmentally-friendly cement pile is created, and the effects of reducing the capital investment and shortening the construction period of a project are realized. 本发明公开了种提高淤泥区水泥搅拌桩强度的方法，该方法提出了组抗压强度公式，计算得到需要掺砂的比例，完成水泥搅拌桩的施工；该发明还提出了种掺砂装置，该装置能够结合计算结果合理有效地完成搅拌桩施工，本发明所述方法能够在不增加水泥掺量及养护龄期的前提下，掺入比例合适的
