Fast construction method for embedded turnout system

Abstract

The invention discloses a fast construction method for an embedded turnout system. The fast construction method comprises the steps that a base is poured on a construction site, positions of a road center line, an outline of a turnout plate and an outline of a slab joint are marked on the top surface of the base, and an isolation layer is paved on the top surface of the base; the turnout plate ispaved in a precast factory, a plate adjusting tool for adjusting the horizontal position and elevation is installed on a lifting position; an elastic pad plate and a height adjusting pad plate are installed in a rail bearing groove of the turnout plate; a steel rail part is placed in the rail bearing groove of the turnout plate and installation and welding are completed; after a rail waist of thesteel rail part is bonded with a damping block, a geometric form and position is adjusted, and the steel rail part is fixed temporarily; a switch rail is installed; macromolecule composites are poured; a point machine is connected with a traction point of the tip of the switch rail by a screw rod; positioning and fixation of the embedded turnout system is performed; and a mortar layer is poured. According to the fast construction method for the embedded turnout system, most of the steps can be completed in the factory, the construction speed on the site is extremely fast, and the whole construction process is scientific and reasonable.

Description

technical field [0001] The invention relates to a rapid construction method for an embedded turnout system, belonging to the technical field of rail transit road construction. Background technique [0002] The embedded track uses polymer materials to continuously support and lock the rail parts, which has a good effect of shock absorption and noise reduction. The vibration and noise generated by the train running have little impact on the living environment of residents near the line. The turnout is the most important in the entire line. One of the weak links, its construction quality has a great impact on the efficiency of line use and the safety, stability and comfort of train operation, especially in sections with large traffic and passenger flow, the construction efficiency of the line is also highly affected Pay attention to. In the existing patent literature, there is no related construction method about the embedded track turnout system. At present, only the patent ...
