First embodiment
As shown in Figure 1-3, the two sides of the railway bed include side slope the embodiment of the invention provides a kind of railway bed And the filler between the side slope of two railway beds.Described Fig. 1, Fig. 2 and Fig. 3 illustrate the feelings of side slope difference ratio of slope Condition, wherein Fig. 3 is high abrupt slope, and ratio of slope can achieve 1:0.5.
Wherein, the side slope includes geotechnical grid 11, support column 21 and toe wall 31.The geotechnical grid 11 is from bottom to top It stacks.Roadbed filling 41 is filled in the cell compartment of the geotechnical grid 11.In the geotechnical grid 11 of neighbouring two Between be filled with preset height roadbed filling 41.The bottom of the geotechnical grid 11 is fixed in the upper end of the support column 21, The lower end of the support column 21 is inserted into the roadbed filling 41 of 11 lower section of geotechnical grid.The toe wall 31 is located at bottom Geotechnical grid 11 side-lower.Specifically, the support column 21 can be steel nail.In this way, support column is firm, service life It is long.
Wherein, in the width direction of roadbed, the outer end of the geotechnical grid 11 of lower section is than the geotechnological lattice of top The length of wide two cell compartments in the outer end of room 11.
Wherein, the geotechnical grid 11 include base layer (being not shown) and the surface layer that is coated on outside base layer (being not shown), the base layer is formed by connecting for steel wire, and the surface layer is plastic material.Specifically, the steel wire Elongation is lower, i.e., the described steel wire is made of the higher steel of tensile strength, such as can be medium carbon steel.Steel wire can be one kind Muscle ability or skeleton, and plastics are covering material.Specifically, the geotechnical grid is two-way geotechnical grid.In this way, can bear multiple The load in direction.
Wherein, the height of the geotechnical grid 11 is 0.15 meter, and the cell compartment width of the geotechnical grid 11 is 0.3 meter;Institute The transverse width for stating the geotechnical grid of roadbed two sides is greater than or equal to 3 meters.It should be noted that attached drawing is not drawn strictly in proportion System.
Wherein, 41 height of roadbed filling of neighbouring two 11 central fillers of geotechnical grid is 0.6 meter.
Wherein, the height of the support column 21 is 2~4 times of 11 height of geotechnical grid.
Wherein, in the longitudinal direction of the roadbed, the spacing of adjacent supports column 21 is 0.3~0.7 meter.
Second embodiment
In order to better understand railway bed, the work progress of the railway bed is described below, the process includes such as Lower step:
Step 501: building toe wall 31 on ground.It is all built in the two sides of roadbed, the distance of two stifled toe walls 31 is roadbed Width.Specifically, toe wall uses M10 mortar flag stone.In this way, stronger.Before building toe wall, smooth location item is answered Part, guarantee roadbed levelling of the land, uniformly.Smooth location and the construction of foot wall are identical as conventional method.
Step 502: roadbed filling 41 is filled between two stifled toe walls 31.The roadbed filled between two stifled toe walls 31 Filler 41 needs to be higher by the certain height of toe wall 31.Geotechnical grid 11 can in this way will not be laid in short transverse too close, Reduce cost.
Step 503: sequentially stacking geotechnical grid 11 on the roadbed filling 41 above toe wall 31.When stacking, in addition to soil It needs to fill outside roadbed filling 41 in the cell compartment of work cell compartment 11, filling roadbed is also needed to fill out between geotechnical grid 11 and geotechnical grid 11 Material 41.It is too close that this can also make geotechnical grid 11 that will not be laid with, and reduces cost.
In addition, when stacking, on the roadbed filling 41 that needs to be fixed on geotechnical grid 11 by support column 21 lower section.That is institute The bottom of the geotechnical grid 11 is fixed in the upper end for stating support column 21, and the geotechnical grid is inserted into the lower end of the support column 21 In the roadbed filling 41 of 11 lower sections.In the geotechnical grid 11 on fixed upper layer, than lower section the geotechnical grid 11 to Roadbed center is retracted preset length.
Pave above geotechnical grid filler when, discharging equipment and panel distance be no less than 1.0m, equipment must not be not It covers and is travelled in the cell compartment of filler.Forbid directly to roll geotechnical grid, forbids to be laid with the soil-shifting of (stress) direction along cell compartment.Meeting in this way Damage geotechnical grid.
Step 504: the 11 roadbed paving filler 41 of geotechnical grid in roadbed the top.It is default to be higher by the geotechnical grid 11 Highly, it is related that it is laid with which kind of rail on this preset height and roadbed, does not repeat.
Step 505: trees 51 are planted in the side slope of the two sides of roadbed.I.e. in the cell compartment that geotechnical grid 11 exposes two sides Plant trees 51.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention, it is all Made any modifications, equivalent replacements, and improvements etc. within the spirit and principles in the present invention, should be included in protection of the invention Within the scope of.
