The invention discloses a ship lock water delivery gallery and a construction method thereof.The ship lock water delivery gallery comprises a pouring foundation and a water delivery vestibule arranged on the pouring foundation in the water delivery direction, the water delivery vestibule comprises a UHPC inner vestibule arranged on the pouring foundation and mass concrete wrapping the UHPC inner vestibule, and the UHPC inner vestibule comprises a plurality of UHPC gallery sections spliced in the water delivery direction; every two adjacent UHPC corridor sections are connected through a section splicing seam, a section water stop ring is arranged between every two adjacent UHPC corridor sections, each UHPC corridor section comprises a plurality of UHPC prefabricated vestibules connected in the water conveying direction, and every two adjacent UHPC prefabricated vestibules in the UHPC corridor sections are connected through a UHPC wet seam. According to the ship lock water delivery gallery, the UHPC prefabricated structure is creatively adopted on the ship lock water delivery gallery to serve as the inner formwork, the construction procedures of formwork erecting and dismantling are weakened, temporary supporting construction is reduced, and construction is easy.

本发明公开了一种船闸输水廊道及其施工方法，包括浇筑基础以及沿输水方向设于浇筑基础上的输水通廊，输水通廊包括设于浇筑基础上的UHPC内通廊以及包覆在UHPC内通廊外的大体积混凝土，UHPC内通廊包括多个沿输水方向拼接的UHPC廊道节段，相邻的两个UHPC廊道节段通过节段拼接缝连接，相邻的两个UHPC廊道节段之间设有节段止水环，UHPC廊道节段包括多个沿输水方向连接的UHPC预制通廊，UHPC廊道节段中相邻的两个UHPC预制通廊通过UHPC湿接缝连接。本发明提供的船闸输水廊道，在船闸输水廊道上创造性地提出了采用UHPC预制结构作为内模，减弱了模板搭设和拆除的施工工序，减少了临时支护的施工，施工简单。
