Abstract

The invention provides an upper-span existing line construction safety protection device and a construction method thereof, and relates to the technical field of upper-span existing line construction.The protection device comprises a base assembly, a plurality of groups of protection assemblies and a first fixing piece, wherein the base assemblies are respectively arranged on two sides of an existing line; a plurality of groups of protection assemblies are bridged and arranged on two groups of base assemblies; the first fixing piece is used for fixing two adjacent groups of protection assemblies; a sliding assembly is arranged between the base assembly and each group of protection assemblies; each group of sliding assembly comprises a slide rail arranged on each group of base assembly; aplurality of pulleys are rotationally arranged at the bottom end of each protection assembly and can slide along the slide rail; and an anti-slip block is arranged on the slide rail and is used for fixing the pulleys. When in use, the base assemblies are buried on the two sides of the existing line, the sliding rails are arranged on the base assemblies, the protection assemblies in each group arearranged in sequence, the protection assemblies are hoisted and arranged on the sliding rails by a crane, and the multiple groups of protection assemblies are pushed to be spliced and fixed in sequence. The upper-span existing line construction safety protection device and the construction method thereof have the advantages of convenient disassembly and assembly and labor-saving.

Description

technical field [0001] The invention relates to the technical field of over-spanning existing line construction, in particular to a safety protection device for over-spanning existing line construction and a construction method thereof. Background technique [0002] Existing lines refer to the lines that have been built before, including railways, expressways, subways, etc. With the development of my country's economy, the total mileage of expressways, subways, and high-speed rails has also developed by leaps and bounds. With the increase of the mileage, it is inevitable that the lines will cross each other, and some construction debris may fall into the operation area of ​​the existing line during the crossing construction process, which will pose a certain threat to the existing line, which is very dangerous. When constructing a new line that crosses an existing line, in order to reduce the impact on the existing line, if the construction of the new line is carried out duri...
