Section, can also partially be set as stop section.The stop section, which is arranged, can facilitate the entrance elevator of the orderly safety of vehicle
Structure steadily can efficiently reach rear gentle slope section.Shown flat slope section can fill water penetration and gather materials, and be set as water-permeable pavement.
Shown water-permeable pavement can prevent pavement of road ponding.Waterproof layer can be laid in the substrate of flat slope section.Due to preceding gentle slope section
The gradient be able to satisfy dewatering needs, may be configured as waterproof pavement, water flow is led by the lateral sulcus of cutting two sides or the side slope of embankment
Out.And the flat slope section gradient is not to be able to satisfy longitudinal drainage demand close to 0 or equal to 0, therefore be designed as water-permeable pavement help
Draining, moisture are easy intrusion roadbed substrate, are laid with waterproof layer in flat slope section substrate.
More than, in order to further increase vehicle transhipment safety, flat slope can be located in the vehicle approaching side of elevating mechanism
Security mask door 16 is arranged in section road surface.Some vehicles enter after elevating mechanism, reach elevating mechanism carrying capacity or
When elevating mechanism is currently running, shield door can be closed.The height of the shield door can be according to the height of driving vehicle
It is adjusted, for example, the height of shield door can be set to 2~3 meters.
In the present embodiment, since downward grades are delayed in -2% when, length of grade is unrestricted, and in order to meet draining need
It asks, downward grades are preferably suddenly in -0.5%.Therefore, the gradient of the rear gentle slope section can be -2%~-0.5%.Further, after
The gradient of gentle slope section can be set to -1.9%~-0.6%, for example, the gradient of rear gentle slope section can for -1.5% or -
1.0%.The length of grade of gentle slope section can be determined according to actual landform situation afterwards.
In the present embodiment, the flat slope Duan Lu between high and low fall formed between the section of the gentle slope flat slope Duan Yuhou in order to prevent
There is avalanche in base, influences the normal operation of elevating mechanism, as shown in Figure 1, being provided with earth-retaining layer 17 between high and low fall.It is shown
The key dimensions such as thickness, height and the area of earth-retaining layer 17 can carry out true according to the soil pressure distribution result of real road
It is fixed.The top surface of shown earth-retaining layer can be flushed with road surface, and elevating mechanism can be can smoothly enter by being conducive to vehicle.Shown earth-retaining layer
It can be metal structure or reinforced concrete structure.Certainly, the material of retaining wall of the invention is without being limited thereto, other can prevent
The material that only soil layer collapses also may be used.In order to keep earth-retaining layer more firm, earth-retaining layer bottom base can be set in the bottom of earth-retaining layer
Plinth 18, as shown in Figure 1.
More than, the stability of earth-retaining layer in order to further increase, if can be arranged inside earth-retaining layer 17 equally distributed
Dry drain hole 21, as shown in Fig. 2 (a) (18 in figure be earth-retaining layer base foundation).The drain hole 21 can be spaced certain
Distance is set in earth-retaining layer.The drain hole 21 can naturally release the flowing water in roadbed, ensure the stability of roadbed, with
Exempt from the soil pressure that ponding increases earth-retaining layer.The size of the scale visual water discharged amount of drain hole is configured.For example, the ruler of drain hole
The very little circular hole that 100mm × 100mm, the square hole of 150mm × 200mm or diameter 50mm~150mm can be respectively adopted.Drain hole
Spacing between drain hole can be 2m × 3m, and the spacing between certain drain hole can be carried out according to the actual amount of water at scene
It determines.For example, the pitch of holes of arid area can suitably increase, the pitch of holes of area of heavy rainfull can suitably reduce.Drain hole
It can be staggered up and down between eyelet.Drain hole and draining blockage in order to prevent, can be in drain hole and roadbed

Loaded filter can add cobble or synthetic material using the sand of 200mm~400mm thickness.In order to preferably sluice, drain hole can
Gradually tilted to the ground along the direction of water flow using tilting drain hole (such as Fig. 2 (a) shown in), the inclined gradient can be with
It is 3.5%~6.5%, for example, the inclined gradient can be 5%.
Vertical drainage pipeline 23 and transverse drainage duct 24 can also be either internally or externally arranged in the earth-retaining layer.It is shown
One end of vertical drainage pipeline connects with the water outlet of the drain hole, and the other end is connect with the transverse drain.It is described perpendicular
To drainpipe along the side (for example, side far from flat slope section roadbed) for being set to earth-retaining layer perpendicular to ground direction, can incite somebody to action
Water inside drain hole is guided to the bottom of earth-retaining layer or by the position of lower part, by being set to bottom and along road Cross Section
The transverse drain discharge of direction setting.The radical of vertical drainage pipe can be according to the quantity of drain hole, arrangement and water discharged amount
It is configured.For example, can be by the drain hole for being located at same row arrangement and a vertical drainage Guan Lian for being provided with multiple apertures
It connects.
As shown in Fig. 2 (b), vertical drainage pore position 25 can also be arranged in the side of the earth-retaining layer.The vertical drainage
Pore position 25 can be used for installing the vertical drainage pipe 23.The drainpipe hole location 25 along perpendicular to ground direction, every
Certain distance is configured.Vertical drainage pore position is mutually coordinated with drain hole plan-position, so as to drain hole and vertical drainage pipe
Connection.
Another aspect provides a kind of domatic road staged longitudinal plane structure design methods.Of the invention
In one exemplary embodiment of domatic road staged longitudinal plane structure design method, the domatic road staged vertical section
Structure can refer to the staged longitudinal plane structure recorded in the above exemplary embodiments.The design method may include:
Step S01 obtains ground elevation information.According to the ground elevation information by the domatic road set gradually for
