Technical Field
The utility model belongs to the technical field of bridge construction, relates to trestle construction for assisting the construction of an underwater bridge, and particularly relates to a trestle steel pipe pile sinking construction guide frame.
Background
The trestle is a temporary structure commonly used in the construction of underwater bridges. The trestle usually adopts a steel pipe pile inserted and driven on a river bed as a lower support. When piling bridge steel-pipe pile is inserted on the riverbed that rivers are less and have thick overburden, generally need not to set up the leading truck, but great at rivers, perhaps when the overburden is thinner, the steel-pipe pile receives water impact or end opening atress uneven, inclines easily when inserting and beating, and the straightness is wayward that hangs down, need adjust repeatedly in the work progress, influences the construction progress.
Disclosure of Invention
The utility model aims to solve the problems and provides a trestle steel pipe pile sinking construction guide frame which can improve the inserting and driving precision and speed of the steel pipe pile.
The technical scheme of the utility model is as follows:
the utility model provides a landing stage steel-pipe pile sinking construction leading truck which characterized in that: the device comprises an upper positioning frame and a lower positioning frame which are arranged in parallel from top to bottom, wherein each positioning frame comprises a first longitudinal rod, a second longitudinal rod and a third longitudinal rod which are arranged in parallel, a plurality of transverse rods are welded among 3 longitudinal rods, the plurality of transverse rods are used for separating a plurality of square steel pipe pile positioning holes between the second longitudinal rod and the third longitudinal rod, the number and the interval of the plurality of steel pipe pile positioning holes are consistent with the number and the interval of each steel pipe pile span of a trestle, and a guide wheel is arranged in the middle of 4 inner side edges of each steel pipe pile positioning hole; a certain distance is reserved between the upper positioning frame and the lower positioning frame and the upper positioning frame and the lower positioning frame are connected through a plurality of connecting rods in a welding mode; the lower end of the vertical rod is welded with the first vertical rod of the lower positioning frame, and the upper end of the vertical rod extends to a certain height above the first vertical rod of the upper positioning frame.
The Bailey beam is connected and fixed with the mounted trestle bridge by the pin shaft, so that the mounting is simple and convenient; the steel pipe pile to be inserted and driven is limited in a three-dimensional mode through the two layers of positioning holes, and the inserting and driving precision is high; after the insertion of the one-span steel pipe pile is finished, the one-span steel pipe pile can be moved forward to the next-span circular construction, and the erection speed of the trestle can be effectively increased.
