Technical field
The utility model relates in-strong expansive rock or swelled ground engineering, in particular in-strong expansive rock or expansive soils
Non-fragment orbit foundation stabilization construction.
Background technique
In-expansive rock or swelled ground are excavated with strong dilatancy and overconsolidation in chance water or cutting off-load by force
When, biggish arch power can be generated, this is that expansive rock or expansive soils ballastless track of high-speed railway are built and will be faced
One technical problem.Currently, ballastless track of high-speed railway by expansive rock or expansive soils, is generally changed using bedding and is filled out or single
It is pure that substrate is reinforced using anchor cable or anchor pole, but when expansive rock expansive force is larger, level of ground water is shallower, base will be faced with
Bed, which changes, fills out the problems such as depth is big, anchor cable or bolt anchorage are ineffective, bedding is by underground water influence of fluctuations.Therefore, it needs to propose
A kind of novel foundation stabilization construction and construction method, in satisfaction-strong expansive rock or expansive soils ballastless track of high-speed railway
The features such as being laid with and require, and ensuring safe and reliable structure, easy for construction, investment reduction.
Utility model content
The technical problem to be solved by the utility model is to provide in one kind-strong expansive rock or expansive soils non-fragment orbit
Foundation stabilization construction generates top protuberance by expansive rock or expansive soils to avoid cutting, meets high speed railway fragments-free rail
Requirement of the road to ride comfort.
It is as follows that the utility model solves technical solution used by above-mentioned technical problem:
In the utility model-strong expansive rock or expansive soils non-fragment orbit foundation stabilization construction, it is suitable for high-speed iron
Road non-fragment orbit ground including expansive rock or expansive soil foundation and fills bedding square thereon, it is characterized in that: the expansive rock
Or substrate arch bar is set on expansive soil foundation, anchor tie plate is set in the cut slope slope surface of two sides, substrate arch bar and anchor tie plate are adopted
It is integral with reinforced concrete structure and consolidation；In the substrate arch bar, anchor tie plate plate face expansive rock below or swelled ground
The upper end of interval setting anchor cable or anchor pole, anchor cable or anchor pole is fixedly connected with substrate arch bar or anchor tie plate, lower anchor depth position
Below climate influenced layer；The bedding is filled in substrate arch bar plate face.
The utility model has the beneficial effects that substrate arch bar, anchor tie plate and anchor cable or anchor pole are combined into a kind of novel
Resistant heave structure has many advantages, such as that good integrity, Resistant heave ability are strong, waterproof；It is logical to efficiently solve high-speed railway cutting
It crosses expansive rock or expansive soils generates the problems such as top is swelled, meet requirement of the ballastless track of high-speed railway to ride comfort；Knot
Structure is safe and reliable, easy for construction, has broad application prospects.
Detailed description of the invention
Fig. 1 is in the utility model one kind-strong expansive rock or expansive soils non-fragment orbit foundation stabilization construction cross section
Figure.
Shown in figure main member title and corresponding label: substrate arch bar 1, anchor tie plate 2, prestress anchorage cable or anchor
Bar 3, bedding 4, expansive rock or expansive soil foundation D, bedding, which change, fills out depth h.
Specific embodiment
The utility model is further illustrated below by specific embodiment and in conjunction with attached drawing.
Referring to Fig.1, in the utility model-strong expansive rock or expansive soils non-fragment orbit foundation stabilization construction, are applicable in
In ballastless track of high-speed railway ground, including expansive rock or expansive soil foundation D and bedding 4 square thereon is filled.The expansion
Substrate arch bar 1 is set on rock or expansive soil foundation D, anchor tie plate 2, substrate arch bar 1 and anchor are set in the cut slope slope surface of two sides
Pulling plate 2 is integral using reinforced concrete structure and consolidation.The substrate arch bar 1,2 plate face of anchor tie plate expansive rock below or
The upper end of interval setting anchor cable or anchor pole 3 in swelled ground, anchor cable or anchor pole 3 is fixedly connected with substrate arch bar 1 or anchor tie plate 2, under
Portion's anchorage depth is located at climate influenced layer or less.The bedding 4 is filled in 1 plate face of substrate arch bar.
Referring to Fig.1, substrate arch bar 1, anchor tie plate 2 and prestress anchorage cable or anchor pole 3 are combined into a kind of novel Resistant heave knot
Structure, prestress anchorage cable or anchor pole 3 provide biggish withdrawal resistance, can offset the arch power of expansive rock or swelled ground.The substrate of arc
Arch bar 1 and slope surface anchor tie plate 2, which pour, builds up an entirety, when expansive rock or swelled ground swell, substrate arch bar 1 can effectively by
Big power passes to slope surface anchor tie plate 2, and slope surface anchor tie plate transmits the force to slope surface prestress anchorage cable or anchor pole 3 again, so that structure
Whole uniform force effectively offsets the expansive force of substrate expansive rock.Meanwhile substrate arch bar 1 poured with anchor tie plate 2 build up one it is whole
Body can effectively reduce water to railway sub-grade in substrate arch bar 1 and laying water-proof coiled material after anchor tie plate 2 when level of ground water is higher
4 influence.The structure efficiently solves high-speed railway cutting and generates top by expansive rock or expansive soils
The problems such as protuberance, meets requirement of the ballastless track of high-speed railway to ride comfort, and structure is safe and reliable, easy for construction, has wide
Application prospect.
The section of the substrate arch bar 1 is arc-shaped, radius of curvature by width of the subgrade surface, change fill out both depth h determine,
Thickness is preferably greater than 0.5m, and Ying Caiyong armored concrete pours.2 thickness of anchor tie plate should be identical as substrate arch bar 1, main reinforcement
It should be welded with main reinforcement in substrate arch bar 1.Spacing, radical and anchorage length is arranged in the prestress anchorage cable or anchor pole 3 should be according to swollen
The expansive force of swollen rock, which calculates, to be determined, anchorage depth should be located at climate influenced layer or less.
Referring to Fig.1, in the utility model-strong expansive rock or expansive soils non-fragment orbit foundation stabilization construction press following step
Suddenly it constructs:
1. classification excavating cut slope side slope simultaneously carries out reinforcement protection, until 2 elevation of top surface of anchor tie plate；
2. excavating the soil body in 2 range of anchor tie plate, construct in cut slope slope surface prestress anchorage cable or anchor pole 3 are existed side by side
Mould forms prestressed anchor pulling plate structure, in anchor tie plate 2 and the reserved connection reinforcing bar of 1 seam crossing of substrate arch bar；
3. excavating the 4 part soil body of bedding, construct on expansive rock or expansive soil foundation D prestress anchorage cable or anchor pole 3 are existed side by side
Anchor tie plate 1, substrate arch bar 2 are poured and build up an entirety by mould；
4. construct top bedding 4, ditch etc..
The above is only using illustrating in the utility model one kind-strong expansive rock or expansive soils non-fragment orbit
Some principles of foundation stabilization construction, are not intended to shown in being confined to the utility model and described specific structure and applicable model
In enclosing, therefore all corresponding modifications that may be utilized and equivalent, belong to the applied patent model of the utility model
It encloses.
