Pile foundation protection formwork for bridge construction

Abstract

The invention discloses a spliced pile foundation protection formwork convenient to disassemble for bridge construction. The spliced pile foundation protection formwork comprises a base formwork, transverse supporting seats, a belt pulley, a straight rack and a plane gear, wherein a pile foundation supporting seat is arranged right above the base formwork, first supporting column formworks are arranged right above the pile foundation supporting seat, a second supporting column formwork is connected between the first supporting column formworks, reinforcing ribs are welded and fixed to the outer side of the second supporting column formwork, the transverse supporting seats are connected to the outer sides of the first supporting column formworks in an attached mode, a positioning sleeve is connected between the transverse supporting seats in a clamped mode, and a top cap formwork is arranged right above the second supporting column formwork. According to the spliced pile foundation protection formwork convenient to disassemble for bridge construction, locking concave blocks and stress supporting blocks are arranged, the left side and the right side of the second supporting column formwork are clamped and locked through the locking concave blocks, then the joints of the second supporting column formwork and the first supporting column formworks are sealed, and the convenience of formwork assembly and disassembly is improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a spliced ​​and easy-to-remove pile foundation protective formwork for bridge construction. Background technique [0002] In the process of bridge construction, the bridge supports and limits the bridge deck through the pile foundation, and the cylindrical rods embedded in the soil are used to transfer the load of the superstructure to the deep hard and less compressible soil layer or rock layer. , due to different problems in the foundation during the construction of different bridges, when the foundation belongs to soft subsidence soil, it is necessary to manually pour the pile foundation to ensure the stability of the bridge during the construction process, and use spliced ​​pile foundation protection templates that are easy to dismantle Yes, it mainly protects the surface of the pile foundation to avoid damage or deterioration during the concrete curing stage; ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a spliced ​​and easy-to-remove pile foundation protection formwork for bridge construction, to solve the problem that the existing formwork proposed in the above-mentioned background technology is generally fixed by welding or binding, and it is difficult to adjust different types of formwork according to the diameter of the concrete. The formwork is assembled and locked, and the joints of the formwork are prone to loosening or water seepage. The pile foundation formwork itself needs to be driven and locked vertically, and it is difficult to adjust the distance between multiple groups of pile foundation protection formworks according to the needs of pile foundation support.
