[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-2 The utility model provides a technical solution: a clamp-type jacking operation platform, comprising a clamp 2 arranged on the outside of a pier 1, the clamp 2 is composed of two semicircular rings, a fixing plate is integrally formed at the contacting position of the two semicircular rings, a through hole is opened on the side surface of the fixing plate, and a fixing bolt Ⅰ3 is arranged in the through hole; a Bailey piece 6 is connected to the clamp 2 through a supporting portion 4, square wood 7 is evenly arranged on the upper surface of the Bailey piece 6, a connecting plate 8 is horizontally arranged on the upper surface of the square wood 7, a template 10 is arranged on the upper surface of the connecting plate 8, and an operating platform 11 is arranged on the inner side of the template 10. By utilizing the steel box beam pier structure and combining the pier cap beam clamp-type construction method, the jacking operation platform is clamped on the pier, which can greatly reduce the construction cost of the bracket, does not require piling operations, and the safety of the permanent structure is also relatively reliable.
[0018] The preferred technical solution is that the support part 4 is a sand cylinder, which is a common temporary support. The steel pipe, steel plate and sand used in the sand cylinder have high compressive strength and are not easy to deform.
