Summary:Provided is a foundation pit bracing water stopping structure with a support pile and a three-axis stirring pile arranged in a cased drilling manner. The support pile is constructed on the outer side of a foundation pit; the stirring pile is constructed in a support pile area in a three-axis stirring manner; and the support pile directly cuts a pile body on the three-axis stirring pile for construction, and the whole bracing water stopping structure is formed. The three-axis stirring pile is large in power, and can perform stirring in strong-weathered rock and the above stratum. Compared with a conventional small diameter cement stirring pile, the beneficial effects of being small in number of lap joints, good in water stopping effect, high in construction efficiency, high in stratum adaptability and the like are achieved; and compared with a jet grouting pile, the beneficial effects that the water stopping effect is good, and price is low are achieved. According to the foundation pit bracing water stopping s
