All-casing process prefabricated expanded-base reinforced composite pile and construction method thereof
The invention relates to an all-casing process prefabricated expanded-base reinforced composite pile and a construction method thereof. The all-casing process prefabricated expanded-base reinforced composite pile is composed of a PHC pipe pile prefabricated part, an expanded-head prefabricated part, heterotopic curing powder backfill soil and an end reinforcing body. After the PHC pipe pile prefabricated part and the expanded head prefabricated part are hoisted into the casing pipe, the end reinforcing bodies and the different-position curing powder backfill soil are formed in a recharging mode in sequence, and therefore the prefabricated expanded-base reinforced composite pile manufactured through the full-casing-pipe process is formed. The pile end bearing capacity of the pile foundation can be remarkably improved, construction is convenient and fast, slurry pollution is avoided, disturbance to surrounding soil is avoided, the method is suitable for various soil layers and can also enter rocks, and economic benefits are high.
本发明涉及一种全套管工艺预制扩底加强复合桩及其施工方法，所述的全套管工艺预制扩底加强复合桩由PHC管桩预制构件、扩大头预制构件、异位固化粉回填土和端部加强体组成。所述的端部加强体、异位固化粉回填土在将PHC管桩预制构件、扩大头预制构件吊入套管之后，先、后通过回灌的方式形成，从而形成全套管工艺预制扩底加强复合桩。本发明能显著提高桩基的桩端承载能力，施工便捷、快速，无泥浆污染，对周边土体无扰动，适用于各种土层，也可以入岩，经济效益高。
