Construction method of CRTS III plate type ballastless track
The invention discloses a construction method of a CRTS III plate type ballastless track and belongs to the technical field of ballastless tracks. The construction method of the CRTS III plate type ballastless track comprises the following steps: building a track control network; implementing on-site paving construction of a roadbed supporting layer or an over-bridge base; paving a middle isolating layer and steel bar meshes on the supporting layer or the base; primarily regulating and placing an III type track plate; precisely regulating and placing; pouring a self-compacting concrete layer. According to the construction method disclosed by the invention, the ratio of base concrete to the self-compacting concrete and subsequent maintenance measures are controlled, and cracks of the base concrete and floating mortar air bubbles of the self-compacting concrete are controlled to ensure that the base concrete and the self-compacting concrete can be poured in all seasons without being affected by environmental temperature changes; during construction, precision requirements on construction measurement and track plate location are extremely high; process control is extremely strict, so that high comfort of a train in running can be better guaranteed.
