Abstract

The invention discloses a porthole protective device of a bridge pile hole. The porthole protective device comprises a pair of concave plane frames symmetrically paved in a porthole of the pile hole,expanded metal welded to the top surfaces of the concave plane frames, plate overturning frames arranged at the notches of the concave plane frames, steel wire mesh welded to the plate overturning frames, protective railings arranged at the notch edges of the concave plane frames and moving doors arranged on the protective railings, the plate overturning frames are rotatably connected to the bottom sides of the notches of the concave plane frames through hinged chains, and the moving doors are rotatably connected with the protective railings through hinged chains. According to the porthole protective device, safety and reliability of bridge pier hole construction can be improved, construction mounting and disassembling are convenient, multiple times of recycling using can be achieved, thewhole porthole surface and the stand surface can be protected in a fully-enclosed mode, and construction safety and personal safety are guaranteed. The porthole protective device is suitable for protection of all kinds of pile hole portholes.

Description

technical field [0001] The invention relates to a hole protection device for bridge pile holes, belonging to the technical field of bridge construction protection. Background technique [0002] In the construction of pile holes in bridge engineering, it is usually necessary to protect the pile holes. Prior art is to adopt diameter to be 48mm, and the fastener type steel pipe that wall thickness is 3.6mm builds up the paint of brushing red and white as warning sign, or do not do any protection in the orifice plane scope. Or use reinforced welded steel mesh for protection. The protection measures in the prior art, the opening protection operation is very inconvenient, the plane steel bar protection net is easily deformed when pulled out, and the steel pipe facade protection railing is mostly empty for workers to operate, and cannot form a fully closed protection for the opening. The effect is not good, and the safety risk in the operation process is great. Work that is pron...
