Abstract
A kind of reinforcing construction preventing non-fragment orbit basement high, the arch effectively to prevent soft rock heavy cut swell, reduce the risk of secondary protuberance, meet requirement of the high-speed railway to Track regularity.It includes armored concrete loading plate, elastic high compression layer and armored concrete anchoring stake, armored concrete anchoring stake, which lays along reinforced concrete loading plate lateral separation and is partitioned into arrangement along circuit extending direction, to be set, and the upper end is rigidly connected with armored concrete loading plate；The top of the armored concrete anchoring stake passes through protuberance stratum, and slides vertically layer along pile body setting；Armored concrete anchoring stake lower anchor increases the ring that rubs in stablizing in rock stratum along pile body setting stake week, in stake bottom setting stake bottom anchorage head；The elasticity high compression layer is set between armored concrete loading plate bottom surface and protuberance surface of stratum.
Description
Technical field
The utility model is related to a kind of reinforcing constructions preventing non-fragment orbit basement high, can be used for railway engineering, highway
The fields such as engineering, arch pre-reinforcement or training works especially suitable for non-fragment orbit railway soft rock heavy cut.
Background technology
In Mountainous high speed railway construction process, the cross-sectional form of soft rockmass heavy cut is inevitable, and soft rockmass generally has
There are off-load rheological behavior and expansion characteristics, the two that can cause the lasting arch of high speed non-fragment orbit railway to a certain extent, this
Kind arch trend lasts for several years or even many decades.In recent years, it runs or in the disease for building non-fragment orbit soft rock heavy cut protuberance
It frequently occurs, and renovates extremely difficult.It was verified that take the flexible measure such as anchor cable ineffective to resist protuberance, and it is simple
Pile slab structure reinforcement measure the shortcomings of growing up there are the long mistake of stake, and there are the risks of secondary protuberance.Therefore it is badly in need of a kind of novel
Construction solves such problem.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of reinforcing construction preventing non-fragment orbit basement high,
Effectively to prevent the arch protuberance of soft rock heavy cut, the risk of secondary protuberance is reduced, meets high-speed railway to Track regularity
It is required that.
Technical solution is as follows used by the utility model solves the technical problem：
A kind of reinforcing construction preventing non-fragment orbit basement high of the utility model, it is characterized in that：It includes that reinforcing bar is mixed
Solidifying soil loading plate, elastic high compression layer and armored concrete anchor stake, and armored concrete anchors stake along armored concrete loading plate
Lateral separation lays and is partitioned into arrangement along circuit extending direction and sets, and the upper end is rigidly connected with armored concrete loading plate；Institute
The top for stating armored concrete anchoring stake passes through protuberance stratum, and slides vertically layer along pile body setting；The reinforced concrete anchors
Gu stake lower anchor increases the ring that rubs in stablizing in rock stratum, and along pile body setting stake week, in stake bottom setting stake bottom anchorage head；The elasticity
High compression layer is set between armored concrete loading plate bottom surface and protuberance surface of stratum.
The utility model has the beneficial effects that there is the location of protuberance trend for soft rockmass heavy cut, divided into loading plate
Elastic high compression layer is set, the influence of soft rockmass heavy cut substrate off-load rheology and expansion characteristics to non-fragment orbit can be solved；In steel
Setting slides vertically layer on reinforced concrete anchor pile, can eliminate the upward friction effects that arch stratum generates stake；In reinforcing bar
It is arranged on concrete anchor pile and increases rub ring and stake bottom anchorage head in stake week, the breakout capacity of anchor pile can be increased substantially, to solve
The certainly long long problem of stake；
Can not only effectively preventing soft rock heavy cut arch protuberance, reduce the risk of secondary protuberance, meet high-speed railway
Requirement to Track regularity, and economy increases substantially, and has broad application prospects.
Description of the drawings
This specification includes following three width attached drawing：
Fig. 1 is a kind of cross-sectional view for the reinforcing construction for preventing non-fragment orbit basement high of the utility model；
Fig. 2 is a kind of skiagraph for the reinforcing construction for preventing non-fragment orbit basement high of the utility model；
Fig. 3 is a kind of plan view for the reinforcing construction for preventing non-fragment orbit basement high of the utility model.
Component, toponym and corresponding label are shown in figure：Stratum A is swelled, good ground B, armored concrete are held
Support plate 1, elastic high compression layer 2, armored concrete anchoring stake 3, slide vertically layer 4, stake week increases rub ring 5, stake bottom anchorage head 6.
Specific implementation mode
This reality utility model is further illustrated with reference to the accompanying drawings and examples.
Referring to FIG. 1, FIG. 2 and FIG. 3, to prevent the reinforcing construction of non-fragment orbit basement high include steel by the utility model a kind of
Reinforced concrete loading plate 1, elastic high compression layer 2 and armored concrete anchor stake 3, and armored concrete anchors stake 3 along reinforced concrete
1 lateral separation of native loading plate lays and is partitioned into arrangement along circuit extending direction and sets, and the upper end is rigid with armored concrete loading plate 1
Property connection.The top of the armored concrete anchoring stake 3 passes through protuberance stratum A, and slides vertically layer 4 along pile body setting, to disappear
The upward friction effects that armored concrete anchoring stake 3 is generated except protuberance stratum A.3 lower part of the armored concrete anchoring stake
It is anchored in stable rock stratum B, and increases the ring 5 that rubs along pile body setting stake week, in stake bottom setting stake bottom anchorage head 6, to increase substantially
Armored concrete anchors the breakout capacity of stake 3, to solve the problems, such as that stake is long long, reduces project cost.The elasticity high pressure
Contracting layer 2 is set between 1 bottom surface of armored concrete loading plate and the protuberance stratum surfaces A, is unloaded with eliminating soft rockmass heavy cut substrate
The influence of lotus rheology and expansion characteristics to non-fragment orbit.The utility model can not only effectively preventing soft rock heavy cut arch it is grand
It rises, reduces the risk of secondary protuberance, meet requirement of the high-speed railway to Track regularity, and economy increases substantially, have
Wide application prospect.
Referring to Fig.1, the top for sliding vertically layer 4 and being located on armored concrete anchoring stake 3, is made of graphite material,
Or lubricant coating is set between sliding vertically 3 outer surface of 4 inner wall of layer and armored concrete anchoring stake.
With reference to Fig. 2, increase the longitudinally spaced setting in lower part that the ring 5 that rubs anchors stake 3 in armored concrete the stake week.The elasticity
High compression layer 2 usually can be used loose sandstone and fill.
The above is a kind of reinforcing construction preventing non-fragment orbit basement high of the utility model that explains through diagrams
Some principles are not intended to the utility model type being confined in shown and described concrete structure and the scope of application, therefore every
It is possible that the corresponding modification being utilized and equivalent, belong to the apllied the scope of the claims of the utility model.
