Construction method of urban railway traffic bolster type steel spring floating slab ballast bed turnout junction
The invention discloses a construction method of an urban railway traffic bolster type steel spring floating slab ballast bed turnout junction. Firstly, an SCP measurement control net is arranged within the construction range, steel rib control piles are implanted into a junction tail bottom plate, retest identification is carried out on pile positions, and during casing of basement concrete, the basement flatness is precisely controlled according to the identification; the mileage and the offset distance of a steel spring vibration isolator are converted into SCP control net coordinates; a total station is utilized for carrying out precise lofting and fixing on a basement, according to the junction position, bottom layer steel ribs are bound firstly, and middle layer steel ribs are arranged in advance; a turnout junction erection part is spliced and roughly adjusted, middle layer junction position ballast bed steel ribs and upper layer junction position ballast bed steel ribs are arranged, and then a fine tuning trolley is adopted in the SCP measurement control net to be utilized for precisely controlling the whole turnout junction to be in place; and fine adjustment is carried out on junction position steel ribs and a vibration isolator outer sleeve, a mold plate is mounted, and floating slab ballast bed concrete is cast.
