Three-axis stirring stiff pile continuous wall foundation pit supporting structure and construction method thereof
The invention provides a three-axis stirring stiff pile continuous wall foundation pit supporting structure and a construction method thereof. The three-axis stirring stiff pile continuous wall foundation pit supporting structure is composed of a crown beam, a three-axis cement soil stirring pile, a prefabricated pile and a reinforcement cage, wherein the prefabricated pile is arranged in the three-axis cement soil stirring pile; the crown beam is arranged on the top of the three-axis cement soil stirring pile; the top of the prefabricated pile is embedded in the crown beam; the reinforcement cage is arranged between the prefabricated pile and the crown beam; and the three-axis stirring stiff supporting pile is composed of the three-axis cement soil stirring pile and the prefabricated pile. According to the three-axis stirring stiff pile continuous wall foundation pit supporting structure and the construction method thereof, the three-axis cement soil stirring pile and the prefabricated pile are combined, soil around the three-axis cement soil stirring pile, the three-axis cement soil stirring pile and the prefabricated pile form a whole, the soil retaining and water isolating functions of the three-axis stirring stiff pile continuous wall foundation pit supporting structure are brought into full play, the stability of the soil around a foundation pit is guaranteed, and meanwhile the coordinated composite function of the three can be brought into play.
本发明提供了一种三轴搅拌劲性桩连续墙体基坑支挡结构及其施工方法，由冠梁，三轴水泥土搅拌桩，预制桩、钢筋笼组成；三轴水泥土搅拌桩内设置预制桩，三轴水泥土搅拌桩的顶部设有冠梁，预制桩顶部嵌入冠梁，预制桩与梁冠之间设置有钢筋笼。三轴搅拌劲性支护桩由三轴水泥土搅拌桩和预制桩组成，本发明通过三轴水泥土搅拌桩与预制桩结合，将三轴水泥土搅拌桩周围土体、三轴水泥土搅拌桩、预制桩形成整体，充分发挥三轴搅拌劲性桩连续墙体基坑支挡结构的挡土和隔水作用，保证基坑周围土体的稳定性，同时能发挥三者的协调复合作用。
