Double-block precast rail seat

Abstract

A double-block precast rail base includes: a precast concrete product consisting of an elastic base plate and an embedded sleeve; the double-block precast rail base is laid on the track bed surface, and several elastic base plates are fixed to the double-block precast rail base at approximately equal intervals, while the rail is fixed to the several elastic base plates; trains travel on it via two parallel track facilities. The elastic base plate on the top surface of the double-block precast rail base generally includes: an elastic base plate and a rail; the double-block precast rail base is laid on the track bed surface, and the elastic base plates are fixed to the double-block precast rail base at approximately equal intervals, while the rail is fixed to the elastic base plate; trains travel on it via two parallel track facilities. The top surface of the double-block precast rail base must be flat where the elastic base plate is installed. This ensures the elastic base plate maintains structural stability and allows the rail force to be evenly distributed to the double-block precast rail base.

Claims

1. A two-block precast rail base, comprising: Two precast rail seats; and two base bodies, each base body surrounding the bottom surface and surrounding surface of the precast rail seat; the base body includes: a body seat; and a body steel mesh embedded inside the body seat, and the body steel mesh consists of several transverse steel bars and several longitudinal steel bars, and the body steel mesh is pre-embedded inside the precast base body, with some steel bars protruding horizontally from the surrounding surface of the precast base body.

2. The dual-block precast rail base as described in claim 1 further includes: at least two anchor sleeves, which are pre-embedded inside the precast base body and protrude vertically from the bottom surface of the precast base body.

3. The dual-block precast rail base as described in claim 1, wherein the dual-block precast rail base has external dimensions of 485x300x92 (mm).

4. The dual-block precast rail base as described in claim 1, wherein the base body further includes a precast base steel mesh, wherein at least one steel bar of the precast base steel mesh is bent and bridging to the body steel mesh.
