Description
Technical field
The present invention relates to railway, Reinforcement of Highway structure, particularly to a kind of high steep embankment reducing differential settlement
Reinforce.
Background technology
In recent years, infrastructure construction enters the high-speed developing period, and railway, road event are built on a large scale, are positioned at mountain area
Railway, highway, due to the violent fluctuating of landform, inevitably need to drop into filling of walking along the street dike at steep slope section.In landform
The low-lying place of landforms, because long-term charge for remittance or farmland planting need, is commonly formed soft foundation, and its sedimentation is higher much larger than physical features
The embankment of side.
At present, railway, the desin speed of highway have had and have been substantially improved, and higher design speed per hour not only needs to control embankment
Bulk settling, for preventing the cracking of pavement structure, the differential settlement of embankment is also the factor needing to control.For such both sides
The high steep embankment that hypsography is bigger, currently mainly uses the embankment to hypsography low-lying side to carry out basement process, reduces work at this
Rear sedimentation, does not considers the lateral variation sedimentation that embankment difference in embankment both sides causes.Landform is the highest compared with the embankment raising of downside, due to
The impact of soft foundation discharging consolidation, settling amount will be much larger than landform upper side.Due to embankment both sides height of embankment difference, certainly will
Cause the relative settlement of embankment both sides, i.e. differential settlement.Differential settlement is the biggest, will result in the cracking destruction of pavement structure,
Impact operation comfortableness, excessive differential settlement is also possible to cause security incident.Therefore, rise and fall for both sides landform height
High steep embankment, needs to seek a kind of bottom stab ilization structure that can effectively control embankment differential settlement.
Summary of the invention
The technical problem to be solved is to provide a kind of high steep embankment ruggedized construction preventing differential settlement, suitable
For the bottom stab ilization structure of the bigger high steep embankment of both sides hypsography, provide a gear reliably for the high steep embankment in mountain area, have
Effect avoids excessive differential settlement, improves highway or the running comfort of high-speed railway, it is to avoid security incident occurs.
The technical solution adopted for the present invention to solve the technical problems is as follows:
A kind of high steep embankment ruggedized construction preventing differential settlement of the present invention is bigger including filling in both sides hypsography
Embankment embankment in side slope, is characterized in that: in described embankment embankment, longitudinally, laterally interval arranges reinforcing pile, under each reinforcing pile
Portion is anchored in embankment embankment；Rigid structural layer, rigid structural layer and each reinforcing pile are set on the end face of described embankment embankment
Stake top consolidation；Fill bed course on described rigid structural layer, on bed course, construct pavement structure.
The invention has the beneficial effects as follows, below road surface structare layer, laid adding of bed course, rigid structural layer and its underpart
Gu stake, the settlement after construction that the high steep embankment of tunable is horizontal, it is greatly reduced the differential settlement on embankment top, is effectively improved at a high speed
Highway or the running comfort of high-speed railway, it is to avoid security incident occurs.
Accompanying drawing explanation
This specification includes following two width accompanying drawings:
Fig. 1 is the cross-sectional view of a kind of lateral pile slab structure being applicable to steep rocky slope embankment of the present invention；
Fig. 2 is the enlarged drawing of A local in Fig. 1
Component shown in figure and corresponding labelling: pavement structure 1, bed course 2, rigid structural layer 3, reinforcing pile 4, embankment is filled out
Side 5.
Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Seeing figures.1.and.2, a kind of high steep embankment ruggedized construction preventing differential settlement of the present invention, including filling in two
Embankment embankment 5 on hypsography larger skirt slope, side.In described embankment embankment 5, longitudinally, laterally interval arranges reinforcing pile 4, respectively adds
Gu the lower anchor of stake 4 is in embankment embankment 5, embankment embankment is reinforced, make embankment form overall stress, it is to avoid roadbed entirety is horizontal
To the difference of rigidity.Rigid structural layer 3, rigid structural layer 3 and each reinforcing pile 4 are set on the end face of described embankment embankment 5
Stake top consolidation, effectively to control the displacement at pile top of reinforcing pile 4, improves stability and the reliability of ruggedized construction.Described rigidity is tied
Fill bed course 2 on structure layer 3, construct pavement structure 1 on bed course 2 and reduce the differential settlement of roadbed.
Described bed course 2 usually permeable structure layer, is filled formed by crushed-gravel or sheet rubble, thickness 0.8～2.5m, depending on
Depending on the roadbed work area degree of depth of highway or railway, for undertaking the additional stress that vehicular load produces.
Described rigid structural layer 3 generally can use armoured concrete slab, thickness 1～2m, by longitudinal length be 5～7m vertical
Constitute to plate, between each longitudinal plate, set expansion joint.The length that the stake top of described reinforcing pile 4 is stretched in rigid structural layer 3 is not less than
100mm。
Described reinforcing pile 4 is the one in reinforced concrete pile, mini pile, reinforced anchor bolt or aggregate pile, depending on high steep embankment
Depending on height of embankment, both sides topographical elevation difference and embankment lateral stability.
Certain highway high roadbed work point, left and right sides hypsography is obvious, and left side landform is high, and right side landform is low, in embankment
Heart raising 10.63m.Left side height of embankment 5.5m, right side height of embankment 20.5m, both sides embankment slope height difference 15m.Right side base
The end is soft foundation, silty clay, soft moulds～stream moulds shape, weak soil thickness about 6m, uses cement mixing pile to process.Left side substrate is covered
Cap rock is relatively thin, about 0.3～0.8m, and subterrane is system Soil Developed From Suining Group sand shale on sieve dwarf.
Scheme 1: traditional design, is layered cape rammer to high side slope of embankment.
The non-soft foundation part in left side, owing to height of embankment is relatively low, base property is good, and the settling amount of filler and substrate is relative
Less.Right side soft foundation is after complex ground treatment, and under the compaction banketed up, substrate discharging consolidation will produce relatively
Big sedimentation；Owing to right side height of embankment is higher, the sedimentation of its filler is also the biggest.Toe, center and slope, right side on the left of embankment
The settling amount of foot is respectively 1.35cm, 4.62cm and 10.4cm, and differential settlement is obvious.
Scheme 2: use the technical scheme of the application
Roadbed part below road surface structare layer, changes back-up sand gravel blanket, and sets armoured concrete slab below bed course, under it
For mini pile, in stake-middle spacing 3m.On the left of embankment, the settling amount of toe, center and right side toe is respectively 1.25cm, 4.24cm
And 7.51cm, differential settlement is greatly reduced.Separately it is arranged at below road surface structare layer due to this structure, uneven in the range of roadbed
Sedimentation, much smaller than 1cm, can effectively prevent the pavement cracking caused due to differential settlement from destroying.
The above a kind of Steep Slope Embankment being applicable to prevent differential settlement of the present invention that simply explains through diagrams adds consolidation
Some principles of structure, are not intended to the present invention be confined in shown and described concrete structure and the scope of application, therefore every institute
The corresponding amendment being likely utilized and equivalent, belong to the apllied the scope of the claims of the present invention.
