PIPE JOINING METHOD
PROBLEM TO BE SOLVED: To inexpensively provide a pipe joining method which can obtain a grout joining structure having strength characteristics such as desired compression strength, tensile strength and bending strength in a short period of time.SOLUTION: In a pipe joining method which joins a lower end side of a connecting pipe and an upper end side of a foundation pile by filling a grout material between an external peripheral face 3A of the foundation pile 3 and an internal peripheral face 4A of the joining pipe 4 which oppose each other, an underwater non-disjunction grout material (short-fiber mixed underwater non-disjunction mortar 6) is filled into a lower end part which is located in water between the external peripheral face of the foundation pile and the internal peripheral face of the joining pipe, and after the grout material is coagulated, a water component of an upper part of a grout lower layer 6A is discharged to the outside from a clearance between the external peripheral face of the foundation pile and the internal peripheral face of the joining pipe, the grout material 7 is filled between the external peripheral face of the foundation pile and the internal peripheral face of the joining pipe at the upper part of the drained grout lower layer, and a grout upper layer 7A is formed.SELECTED DRAWING: Figure 2
【課題】所望の圧縮強度、引張強度及び曲げ強度等の強度特性を有したグラウト接合構造を、安価かつ短期間で実現可能な管接合方法を提供する。【解決手段】互いに向かい合う基礎杭３の外周面３Ａと接合管４の内周面４Ａとの間にグラウト材を充填することによって、接合管の下端側と基礎杭の上端側とを接合する管接合方法において、基礎杭の外周面と接合管の内周面との間の水中に位置される下端部に水中不分離性グラウト材（短繊維混入水中不分離性モルタル６）を充填して形成したグラウト下層６Ａの水中不分離性グラウト材が凝結した後に、当該グラウト下層の上方の水分を基礎杭の外周面と接合管の内周面との間から外部に排水し、その後、当該排水されたグラウト下層の上方の基礎杭の外周面と接合管の内周面との間に、グラウト材７を充填してグラウト上層７Ａを形成した。【選択図】図２
