CONSTRUCTION METHOD FOR NOISE ABSORPTIVE BLOCK FOR RAILBED

摘要

Provided is a construction method for sound-absorptive block for a railbed, capable of manufacturing small sound-absorptive blocks in a factory, coupling the blocks in a construction field to install the same on a concrete bed, thus enhancing conveyance and workability of sound-absorptive blocks. The method for constructing a sound-absorptive block on a concrete bed in which a pair of rails are installed on a sleeper, comprises the steps of: installing a plurality of sound-absorptive blocks between a pair of rails by separating the same from the upper surface of a concrete bed such that a plurality of fastening holes of the sound-absorptive blocks, which penetrate from one end of each of the sound-absorptive blocks to the other end thereof, communicate with each other; allowing a linear member to pass through the fastening holes communicating with each other; and coupling an anchorage to both ends of the linear member and coupling the plurality of sound-absorptive blocks.
