Embodiment
The utility model is introduced below by way of accompanying drawing.It should be noted that it is only for explanation that these, which are introduced,
Principle of the present utility model and provide, be not so limited the scope of the utility model.
Fig. 1 and 2, which respectively illustrates, to be applied to tunnel according to fixed track usage plan device 100 of the present utility model and refoots the bowing of operation
View and front view.As illustrated in fig. 1 and 2, crossbeam 110 is mainly included according to fixed track usage plan device 100 of the present utility model and is indulged
Beam 120.Wherein, some crossbeams 110 are set up in the lower section of rail 20 in a manner of parallel to each other and be spaced apart, for by rail
20 support.So, sleeper (not shown) can be extracted out from the lower section of rail 20.Spacing between adjacent two crossbeams 110 can
Selected according to actual conditions and experience, the total quantity of crossbeam 110 can select according to the length of operation interval.
Fixed track usage plan device 100 also includes two longerons 120, and they are in a manner of parallel to each other and be spaced apart in each horizontal stroke
The end of beam 110 is set up on crossbeam 110.That is, the base 121 (see Fig. 4) of longeron 120 and the top of crossbeam 110
Side 111 fits (see Fig. 3).As shown in Fig. 2 the both ends of crossbeam 110 usually extend to the drainage channel 50 of the both sides of rail 20
Opening position, drainage channel 50 is interior to be filled and led up (shown in the black bars in Fig. 2) by irrigating slurry.Therefore, two longerons 120 are distinguished
It is roughly parallel to the drainage channel 50 of the both sides of rail 20 and extends.
So, intersecting the fixed track usage plan device 100 formed by two longerons 120 and some crossbeams 110 can be effectively
