Backer side lateral sulcus bottom.
Preferably, the guarded drainage layer by be located below the first medium-sand seam, middle composite water drain-proof plate and on
The second medium-sand seam composition in face, the guarded drainage layer are arranged to weathering of the ratio of slope not less than 4%, guarded drainage from backer is laterally outer
The inner side of layer overlaps with the bottom of draining the region between the heart and the diaphragm ditch.
Preferably, the thickness of first medium-sand seam is 0.05m, the thickness of the second medium-sand seam is 0.1m.
Preferably, thickness of the bottom layer of subgrade in roadbed wire center position is thick not less than high-speed railway bottom layer of subgrade
Spend h.
Preferably, the bottom layer of subgrade and surface layer of subgrade bed backer side vertical cut fill, side base of going down the hill bed structure uses
Full dew form, ratio of slope 1：1.5.
Preferably, the delivery port of the draining the region between the heart and the diaphragm ditch sets elevation consistent with guarded drainage layer drainage channel.
Beneficial effect：The utility model can effectively solve high-speed railway swelled ground and reveal expansion caused by formula chasm structuref entirely
Soil excavates Reinforcing High Slope difficult problem, and can meet the functional requirement of high-speed railway subgrade, has economy, construction is simple, ring
The features such as guarantor, there is wide popularizing application prospect.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the utility model one.
Fig. 2 is the structural representation of guarded drainage layer.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in Figure 1 and Figure 2, high-speed railway swelled ground slope chasm structuref of the present utility model includes：Guarded drainage layer 1, paving
It is located on the expansive soil foundation of subgrade bed bottom；Bottom layer of subgrade 2, fill at the top of guarded drainage layer 1；Surface layer of subgrade bed 3, is filled
The top of bottom layer of subgrade 2；Lateral sulcus 4, it is arranged on roadbed both sides；Reinforcing pile 5, it is arranged on excavation cut slope A backer's side slope pin；Draining
The region between the heart and the diaphragm ditch 6, it is arranged on the bottom of backer side lateral sulcus 4.Wherein, guarded drainage layer 1 by be located below the first medium-sand seam 11, middle answer
Close drainable waterproofing plate 12 and the second medium-sand seam 13 above forms, the thickness of the first medium-sand seam 11 is 0.05m, the second medium coarse sand
The thickness of layer 13 is 0.1m, and the guarded drainage layer 1 is arranged to weathering of the ratio of slope not less than 4%, guarded drainage layer 1 from backer is laterally outer
Inner side and draining the region between the heart and the diaphragm ditch 6 bottom overlap joint it is good, draining connection, delivery port and the drainage channel of guarded drainage layer 1 of draining the region between the heart and the diaphragm ditch 6
Set elevation consistent；Thickness of the bottom layer of subgrade 2 in roadbed wire center position is not less than high-speed railway bottom layer of subgrade thickness h, base
Bed bottom 2 and the backer side vertical cut of surface layer of subgrade bed 3 fill, and side base of going down the hill bed structure uses full dew form, ratio of slope 1：1.5.
As shown in Figure 1 and Figure 2, using the water proof and drainage of guarded drainage layer 1, the infiltration of roadbed top layer and underground water are arranged
Go out outside road structure, influence the intensity of expansive soil foundation so as to avoid roadbed surface water seapage, avoid depositing for ground underground water
Influenceing the intensity of subgrade bed structure；By the use of bottom layer of subgrade 2 and surface layer of subgrade bed 3 as the structure stress layer of roadbed, meet high
Fast railway requirement；Railway bed surface and the domatic surface water of excavating cut slope are quickly discharged using lateral sulcus 4；Made using reinforcing pile 5
For the reinforcing force structure of swelled ground excavating cut slope；Using draining the region between the heart and the diaphragm ditch 6, collect backer's dypass base and infiltrate surface water and ground base
