Abstract
The invention discloses a ladder-shaped rail construction method for urban rail transit, which is characterized in that before a ladder-shaped sleeper is in place, foam plates are used for fully pasting parts among all sections of vibration damping pieces on the bottom and the side of the ladder-shaped sleeper according to the thickness same as that of a bottom vibration damping pad and a side cushion pad respectively; hoisting the ladder-shaped sleeper pasted with the foam plate in place, arranging a support, erecting the ladder-shaped sleeper by the support, installing fastener fittings on the ladder-shaped sleeper, laying a steel rail and setting a track state; then, erecting the mould and pouring support concrete; and manually removing the foam plate after the pouring of the support concrete is completed to form the ladder-shaped track in a floating state. The integral ballast bed is formed at one time, the process is simple, the construction efficiency is high, the ladder-shaped sleeper can effectively float, and the performance of vibration reduction and noise reduction is effectively guaranteed.
Description
Technical field
The present invention relates to a kind of job practices, the job practices of the urban track traffic ladder shape track of more specifically saying so
Background technology
Ladder shape track is the new damper rail structure that occurs in recent years, and as Fig. 1, Fig. 2 and shown in Figure 3, its structure is formed and comprised: rail 1, buckle accessory 2, ladder shape sleeper 4 and " L " shape concrete bearing 6; Between ladder shape sleeper 4 and " L " shape concrete bearing 6, form " L " shape fitting face, on " L " shape fitting face, each section " L " type vibration-damped component that is made of bottom cushion blocking 5 and sidepiece cushion pad 7 is set at interval, ladder shape sleeper is made up of left and right sides strip sleeper and the middle steel pipe 3 that connects, pre-buried nylon sleeve in sleeper, be used for the installing tache accessory, the load that is born after the moulding of ladder shape railway roadbed passes to concrete bearing by " L " vibration-damped component, thereby plays the vibration and noise reducing effect.
For the job practices and the indefinite form of ladder shape track, still there is not ripe construction technology at present.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of urban track traffic ladder shape track construction method is provided so that the site operation of ladder shape track can guarantee location, adjustment, railway roadbed moulding accurately, fast and reliable.Technical solution problem of the present invention adopts following technical scheme
The characteristics of urban track traffic ladder shape track construction method of the present invention are:
At first before ladder shape sleeper is in place, in the bottom of ladder shape sleeper and sidepiece respectively according to the thickness identical with the sidepiece cushion pad with the bottom cushion blocking, use cystosepiment that the part between each strand damping spare is sticked;
To post the ladder shape sleeper hoisted in position of cystosepiment then, support will be set, ladder shape sleeper is set up by support, installing tache accessory, steel rail laying and track condition is set on ladder shape sleeper;
Formwork erection is built the bearing concrete again; The artificial cystosepiment of removing after finishing that bearing is concrete and building forms the ladder shape track of floating state.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, solid concrete roabed disposal molding of the present invention, technology is simple, the efficiency of construction height, per work day, construction speed reached 50m～75m.
2, the present invention is behind ladder shape track construction, and ladder shape sleeper can effectively be floated, and has effectively ensured the performance of vibration and noise reducing.
Description of drawings
Fig. 1 is a ladder shape track schematic top plan view of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 1;
Fig. 4 is assembled into section of track schematic diagram for ladder shape sleeper of the present invention.
Number in the figure: 1 rail, 2 is buckled accessory, 3 and is connected steel pipes, 4 ladder shape sleepers, 5 bottom cushion blockings, 6 and be " L " shape concrete bearing, 7 sidepiece cushion pads, 8 supports
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, according to prior art, the structure of ladder shape track is formed and to be comprised: rail 1, buckle accessory 2, ladder shape sleeper 4 and " L " shape concrete bearing 6; Between ladder shape sleeper 4 and " L " shape concrete bearing 6, form " L " shape fitting face, on " L " shape fitting face, each section " L " type vibration-damped component that is made of bottom cushion blocking 5 and sidepiece cushion pad 7 is set at interval, ladder shape sleeper is made up of left and right sides strip sleeper and the middle steel pipe 3 that connects, pre-buried nylon sleeve in sleeper, be used for the installing tache accessory, the load that is born after the moulding of ladder shape railway roadbed passes to concrete bearing by " L " vibration-damped component, thereby plays the vibration and noise reducing effect.
In the present embodiment, adopt following job practices for trapezoidal formula track:
At first, before ladder shape sleeper 4 is in place, in the bottom of ladder shape sleeper 4 and sidepiece respectively according to the thickness identical with bottom cushion blocking 5 and sidepiece cushion pad 7, use cystosepiment that the part between each strand damping spare is sticked; So that ladder shape sleeper 4 constitutes complete plane in the bottom jointly by bottom cushion blocking 5 and bottom foam plate, constitute complete plane jointly by sidepiece cushion pad 7 and side foam plate at sidepiece;
To post ladder shape sleeper 4 hoisted in position of cystosepiment then, support 8 will be set, and ladder shape sleeper 4 be set up by support 8 keep the location, installing tache accessory 2, steel rail laying 1 and adjust track condition on ladder shape sleeper;
Follow assembling reinforcement, install template, build bearing concrete 6; The artificial cystosepiment of removing after finishing that bearing is concrete and building forms the ladder shape track of floating state, makes the load that is born after the moulding of ladder shape railway roadbed pass to concrete bearing by " L " vibration-damped component, thereby plays the vibration and noise reducing effect.
