Concrete-filled steel tube lattice pier without bearing platform for deep reservoir area and construction method of concrete-filled steel tube lattice pier
The invention relates to the technical field of bridge substructure construction, in particular to a bearing-platform-free concrete-filled steel tube lattice pier for a deep reservoir area and a construction method thereof.The bearing-platform-free concrete-filled steel tube lattice pier comprises a concrete-filled steel tube pile foundation and a first lattice pier which are connected in a socket-and-spigot mode, and the bearing-platform-free concrete-filled steel tube lattice pier is connected with the first lattice pier in a socket-and-spigot mode. A transverse connecting system is arranged between every two adjacent steel pipe concrete pile foundations, and the two ends of each transverse connecting system are connected with the different first lattice piers correspondingly. According to the lattice pier structure, a pile foundation bearing platform is omitted, the problems that the construction period is too long and the construction difficulty is increased due to cast-in-place of the pile foundation bearing platform are solved, and meanwhile the risk of pollution to a water body in a deep reservoir area is prevented.
本发明涉及桥梁下部结构施工技术领域，特别涉及一种用于深水库区的无承台钢管混凝土格构墩及其施工方法，其中无承台钢管混凝土格构墩，包括钢管混凝土桩基和第一格构墩，所述钢管混凝土桩基与所述第一格构墩承插式连接，相邻所述钢管混凝土桩基之间设置横向连接系，所述横向连接系的两端分别连接不同的所述第一格构墩。该格构墩结构取消了桩基承台，避免了现浇桩基承台导致的工期过长、施工难度加大的问题，同时防止了对深水库区水体造成污染的风险。
