Brief description of the drawings
This specification includes such as next width attached drawing：
Fig. 1 is a kind of sectional schematic diagram of non-fragment orbit railway swelling rock chasm structuref of the utility model.
Component name and corresponding mark are shown in figure：Prestress anchorage cable 1, pressure relief vent 2, anchor tie plate 3, bottom layer of subgrade 4,
Surface layer of subgrade bed 5, draining lateral sulcus 6, longitudinal french drain 7, cut slope A, climate influenced layer h.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：
With reference to Fig. 1, a kind of non-fragment orbit railway swelling rock chasm structuref of the utility model includes：Pressure relief vent 2, interval
It is arranged in the swelling rock ground being affected by atmospheric effects in the range of depth h；Prestress anchorage cable 1 and anchor tie plate 3, prestress anchorage cable 1
In a row it is disposed in swelling rock ground, its anchoring section is positioned at the swelling rock being affected by atmospheric effects below depth h scopes
In base, anchor tie plate 3 is arranged on swelling rock ground, and is fixedly connected with 1 tensioning of prestress anchorage cable；Bottom layer of subgrade 4 and bedding
Top layer 5, on anchor tie plate 3, surface layer of subgrade bed 5 fills on bottom layer of subgrade 44 placement in layers of bottom layer of subgrade；Draining lateral sulcus 6,
Chasm structuref both sides are arranged on, 6 bottom of draining lateral sulcus sets longitudinal french drain 7.
With reference to Fig. 1, spaced prestress anchorage cable 1 is used for the expansive force for resisting swelling rock, so as to avoid roadbed from sending out
Raw arch deformation.Pressure relief vent 2 is set in the swelling rock ground being affected by atmospheric effects in the range of depth h, is produced for swelling rock
Expansive force and it is upwardly-deformed by limited time provide deformation space, so as to effectively discharge expansive force, reduce to prestress anchorage cable 1 and anchor
The arch active force of pulling plate 3, so that arch deformation will not be produced to top roadbed.The full foamed glue of spray, can keep away in pressure relief vent 2
Exempt from underground water to enter in pressure relief vent 2, while foamed glue has the function of that deformation is resilient etc. greatly.Prestressed anchor is used as using anchor tie plate 3
The top stress supporting structure of rope 1, while it has larger contact area with swelled rock and soil ground, makes roadbed top roadbed knot
