Enclosure method for supporting deep foundation pit with reinforced concrete cast-in-place piles internally connected with miniature steel pipe piles
The invention discloses an enclosure method for supporting a deep foundation pit with a reinforced concrete cast-in-place pile internally connected with a miniature steel pipe pile, and the enclosure method for supporting the deep foundation pit with the reinforced concrete cast-in-place pile internally connected with the miniature steel pipe pile comprises the reinforced concrete cast-in-place pile. According to the enclosure method, the problems that a traditional cast-in-place pile enclosure method in the soil-rock combined binary stratum is large in construction difficulty, low in efficiency, high in cost, large in pollution and the like are solved, and meanwhile the problems that a traditional steel pipe pile external suspended pile enclosure method in the soil-rock combined binary stratum is large in occupied space, high in excavation risk of a reserved platform and the like are solved; according to the enclosure method, soil layer cast-in-place piles and rock stratum steel pipe piles are integrally connected, the advantages of the soil layer cast-in-place piles and the advantages of the rock stratum steel pipe piles are combined, and the soil layer cast-in-place piles and the rock stratum steel pipe piles are jointly stressed and cooperatively deformed; the enclosure method has high popularization value and wide application prospect in the deep foundation pit support of the soil-rock combined binary stratum.
本发明公开了一种钢筋混凝土灌注桩内接微型钢管桩的深基坑支护用围护方法，包括钢筋混凝土灌注桩，本发明所述的一种钢筋混凝土灌注桩内接微型钢管桩的深基坑支护用围护方法，该围护方法解决了土岩组合二元地层中传统灌注桩围护方法的施工难度大、功效低、成本高、污染大等难题，同时也解决了土岩组合二元地层中传统的钢管桩外置吊脚桩围护方法的占用空间大、留台处开挖风险高等问题，该围护方法将土层灌注桩和岩层钢管桩整体连接起来，结合二者优点，使二者共同受力、协同变形，具有安全性高、整体刚度大、占用空间小、施工快捷、造价低等优点，该围护方法在土岩组合的二元地层深基坑支护中具有较大推广价值和广阔应用前景。
