Preferably, pillar is that the cross section of being made up by HW200 shaped steel and steel plate welding is square cylinder.

Preferably, the weight of rail is 60 kilograms/meter.

Preferably, spring III type fastener is the III type elastic bar fastener with nylon gauge regulating block and rubber mat plate, and the spring of spring III type fastener is with nylon gauge regulating block and rail bilaterally-chucked.

Preferably, the pillar height is a 0.8-1.6 rice, and the longitudinal pitch between pillar and the pillar is less than 1.8 meters, 1.505 meters of horizontal spacings.

Preferably, the inspection trench is arranged on the concrete foundation, described trench is under between the two rails, and is dark 0.7 meter, wide 1.1 meters.

Advantage of the present utility model and beneficial effect are: owing to adopted new connected mode between pillar and the reinforced concrete foundation, and easy construction, when using the back sedimentation on the basis, can the cushioning reparation, have favorable applicability; Simultaneously, owing to adopted spring III type fastener, can insulate and damping, thereby guarantee maintenance activity safety, reduce motor-car walking vibration, and can effectively prevent rail creeping overall structure safety and stability, circuit is smooth-going reliable, and economy is strong.

The specific embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.

As shown in drawings, the concrete technical scheme of implementing of the utility model is:

The viaduct that can be used for checkout equipment under the EMUs car, comprise pillar 7 and rail beam 12, pillar 7 adopts steel structural form, cross section by shaped steel and steel plate welding combination is square cylinder, high about 0.8 meter of pillar, pillar 7 upper and lower sides all are welded with bloom base plate, be fixed with basic built-in fitting 5 in the concrete foundation, as the grooved reinforcing bar U-steel muscle 4 M24 bolts that elevated above the soil, the following seat board 4 of steel work pillar 7 links together by 4 groups of M24 anchor nuts 6 and concrete foundation, be connected with rail iron seat 9 on the pillar upper base plate 3, rail iron seat is the cast steel iron seat of an integral precision casting, the upper and lower plates face is made 1: 40 rail cant, improve rail application life, the lower flat plate face of described rail iron seat 9 is connected with pillar upper base plate 3, respectively there is an installation base at the two ends, the left and right sides of the top vertical direction of rail iron seat 9, this installation base bilateral symmetry, be used to assemble spring III type fastener 8, spring by spring III type fastener 8 is nylon gauge regulating block and rail bilaterally-chucked, thereby rail 12 is fixed on the pillar 7.
