Abstract

The invention relates to a jacking pipe joint safety protection device. According to the technical scheme, the jacking pipe joint safety protection device comprises a bottom plate and wheels below thebottom plate, and further comprises two vertical supporting plates; a top cover is connected to the upper side of the bottom plate through supporting columns; the two vertical supporting plates are arranged between the bottom plate and the top cover in a bilateral symmetry mode; the lower ends of the supporting plates are elastically hinged to the bottom plate through the axis in the front-back direction; and the upper ends of the two supporting plates are hinged through an extensible frame. Through connection of the supporting plates and the extensible frame, enough activity space is provided for people and objects; and through mutual linkage between the extensible frame and the supporting plates, the device is actively contracted into a stable supporting state when external force impactis generated, and protection is provided for the people and the objects.

Description

technical field [0001] The invention relates to a safety protection device for pipe jacking construction, in particular to a safety protection device for pipe jacking joints. Background technique [0002] During the pipe jacking construction process, due to the need for joint positioning and grouting of the pipe joints, construction personnel are often required to enter the site for operations. However, since the pipe jacking construction is carried out underground, it is greatly affected by the geology. , pipe jacking collapse accidents are very likely to occur, causing serious on-site accidents; in order to avoid this situation, geological exploration in the early stage of tunnel construction and reinforcement and landfill in unstable areas are essential, but this cannot completely avoid accidents In view of the above situation, the existing technology usually uses the movable equipment in the jacking pipe to guarantee the safety of the construction personnel. However, mos...
