Precast pile with bottom-expanded end plate and construction method thereof
The invention provides a precast pile with an expanded-base end plate and a construction method thereof, and the precast pile with the expanded-base end plate comprises the expanded-base end plate and a precast pile body; the expanded-bottom end plate is connected with the bottom of the precast pile body, the area of the cross section of the expanded-bottom end plate is larger than that of the cross section of the precast pile body, and the expanded-bottom end plate and the precast pile body are coaxially arranged; a through hole matched with the inner hole diameter of the precast pile body is formed in the center of the bottom expanding end plate and used for circulation of concrete or cement mortar or cement soil. According to the configuration, the expanded-base end plate is used for being connected with the bottom of the precast pile body, the cross section area of the expanded-base end plate is larger than that of the precast pile body, the pile end bearing area of the precast pile body is effectively increased, the pile end bearing layer and the pile body strength are brought into play, and the single-pile bearing capacity is improved; meanwhile, material consumption is low, the pile end bearing area is increased, the single-pile bearing capacity is improved, the number of pile foundations can be reduced, and the construction cost is reduced.
本发明提供一种带有扩底端板的预制桩及其施工方法，其中，带有扩底端板的预制桩包括：扩底端板和预制桩本体；扩底端板与预制桩本体的底部连接，其中，扩底端板的横截面面积大于预制桩本体的横截面面积且扩底端板与预制桩本体同轴设置；扩底端板的中心具有与预制桩本体的内孔径相适配的通孔，用于供混凝土或水泥砂浆或水泥土流通。如此配置，扩底端板用于与预制桩本体的底部连接，且扩底端板的横截面面积大于预制桩本体的横截面面积，有效提升了预制桩本体的桩端承载面积，使得桩端持力层和桩身强度得到发挥，提高了单桩承载能力；同时材料耗费少，且桩端承载面积增加，单桩承载能力提高，进而能够减少桩基数量，降低工程造价。
