Abstract

The invention particularly relates to an adjustable type ballastless track self-compacting concrete filled combined template and solves the problems that the precision is relatively bad, the filling quality is bad, the wastes are serious and the cleaning consumes a lot of time when self-compacting concrete is poured by an existing template. According to the invention, a pressing plate is fixed on the outer end face of a template body and a connection end plate is fixed on the outer end face of the template body; a bolt connection hole is formed in the connection end plate; a pressing plate I is fixed on the outer end face of a template body I and a connection end plate I is fixed on the outer end face of the template body I; a bolt connection hole I is formed in the connection end plate I; a cam-shaped pressing disc is arranged on the outer end face of the template body I; a pressurizing elbow is additionally arranged outside an exhausting opening formed by an arc-shaped template body and a vertical template body; a concrete discharging opening is formed in the horizontal bottom section of the pressurizing elbow; a connection end plate II is fixed on the outer surface of the arc-shaped template body; a connection end plate III is fixed on the outer surface of the vertical template body. The adjustable type ballastless track self-compacting concrete filled combined template has the advantages of portability, durability, flexibility, waste reduction and cost conservation.

Description

technical field [0001] The invention relates to a template for high-speed railway construction, in particular to an adjustable ballastless track self-compacting concrete perfusion composite template. Background technique [0002] Slab ballastless track is one of the important forms of high-speed railway ballastless track. Many high-speed railways (passenger dedicated lines) have been built in my country. Recently, my country has independently developed the CRTSⅢ slab ballastless track structure, which uses self-compacting concrete with better fluidity to replace the original asphalt cement mortar as the filling layer between the track slab and the base, which improves the durability of the track structure and reduces the the cost of the track. [0003] However, in the process of pouring self-compacting concrete, the existing formwork has the following disadvantages: [0004] 1. Affect the laying accuracy of track slabs: the design spacing of longitudinal laying of slab-type...
