Abstract
The utility model discloses a lateral pile plate structure applicable to a rocky steep embankment. According to the structure, reliable supporting and retaining can be provided for the mountainous steep embankment, the coordination of the transverse stiffness of a subgrade is effectively controlled, differential settlement is avoided, the running comfort of highways or high-speed railways is improved, and safety accidents are avoided. The lateral pile plate structure comprises cantilever piles (3), reinforced concrete slabs (2) and fill, wherein the cantilever piles (3) are arranged on the lower side of the steep embankment at intervals in the embankment extension direction, and lower parts of the cantilever piles are anchored in a rock mass; the reinforced concrete slabs (2) are laid under a pavement structure layer (1), and outer ends of the reinforced concrete slabs are fixedly connected with tops of the cantilever piles (3); the fill is arranged behind the cantilever piles (3), and geogrids (4) are vertically laid in the fill in a layered manner.
Description
Technical field
The utility model relates to railway, Reinforcement of Highway structure, particularly a kind of side direction stake plated construction that is applicable to steep rocky slope embankment.
Background technology
In recent years, the design speed of railway, highway has had significantly lifting, and high-speed railway, speedway are built on a large scale in mountain area.Because mountain area cheuch is steep, topographic and geologic is complicated, inevitably need on abrupt slope, build roadbed, and higher design speed per hour is also had higher requirement to the integral rigidity of roadbed.For mountain area Steep Slope Embankment, the main stake board wall that adopts is reinforced at present.When natural horizontal wall inscription is steeper, stake board wall jib-length is larger, and malformation and stability are difficult to control, and the whole lateral stiffness of roadbed is uneven, causes the cracking of differential settlement and road structure, causes investment and security risk to be difficult to control.For steep rocky slope embankment, especially cut-fill subgrades, the rigidity that excavation side rock matter substrate rigidity and embankment side are banketed is inconsistent, there is larger difference, for speedway or high-speed railway, the difference of rigidity will cause differential settlement, thereby affect running comfort, and excessive differential settlement also will cause security incident.Therefore, in the urgent need to seeking a kind of reinforcing retaining structure that can solve high steep slope subgrade integral rigidity coordination.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of side direction stake plated construction that is applicable to steep rocky slope embankment, for mountain area Steep Slope Embankment provides a gear reliably, effectively controlling roadbed lateral stiffness coordinates, avoid differential settlement, improve the running comfort of speedway or high-speed railway, avoid occurring security incident.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
A kind of side direction stake plated construction that is applicable to steep rocky slope embankment of the utility model, comprises road surface structare layer, it is characterized in that it also comprises: cantilever pile, at Steep Slope Embankment downside, along embankment bearing of trend interval, arrange, and its underpart is anchored in rock mass; Armored concrete slab, is layed under road surface structare layer, and its outer end is fixedly connected with cantilever pile stake top; Embankment, fills after cantilever pile stake, vertical layered laying geo-grid in it.
The beneficial effects of the utility model are, in road surface structare layer below, have laid armored concrete slab, have avoided the difference of the whole lateral stiffness of roadbed, prevent the differential settlement of roadbed.Meanwhile, armored concrete slab is connected with embankment side cantilever pile stake top, can effectively control cantilever pile stake top displacement, improves stability and the reliability of ruggedized construction, effectively improves the running comfort of speedway or high-speed railway, avoids occurring security incident.

Member shown in figure and corresponding mark: supporting and protection structure 5 between road structure 1, armored concrete slab 2, cantilever pile 3, geo-grid 4, stake.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of side direction stake plated construction that is applicable to steep rocky slope embankment of the present utility model, comprising: cantilever pile 3, at Steep Slope Embankment downside, along embankment bearing of trend interval, arrange, and its underpart is anchored in rock mass; Armored concrete slab 2, is layed under road surface structare layer 1, and 3 tops in its outer end and cantilever pile are fixedly connected with; Embankment, fills after 3 of cantilever piles, and vertical layered laying geo-grid 4 in it, to guarantee a rear soil stabilization, avoids a rear thin unstability of banketing, and necessary drawing-resistant function is provided.In road surface structare layer 1 below, lay armored concrete slab 2, avoided the difference of the whole lateral stiffness of roadbed, prevented the differential settlement of roadbed.Meanwhile, 3 tops of armored concrete slab 2 and embankment side cantilever pile are connected, and can effectively control 3 top displacements of cantilever pile, improve stability and the reliability of ruggedized construction, effectively improve the running comfort of speedway or high-speed railway, avoid occurring security incident.
See figures.1.and.2, between described cantilever pile 3, be fixedly installed supporting and protection structure 5 between stake.Between stake, supporting and protection structure 5 can be the breast boards being fixedly hung on adjacent two cantilever piles 3, or applies shotcrete layer or soil nail wall on embankment lateral surface between adjacent two cantilever piles 3.
Generally speaking, cantilever pile 3 pile body cross sectional dimensions are 1.5m * 1.75m～2.5m * 3m, and the middle spacing of adjacent two cantilever piles 3 is 5～7m; The span of armored concrete slab 2 is 7～12m, and thickness is 0.4～1.5m, and the length that 3 tops of cantilever pile are goed deep in armored concrete slab 2 is not less than 100mm; The length of geo-grid 4 is preferably 4～6m, or elongated laying, the interlamellar spacing 0.6～1.8m of geo-grid 4 in embankment.
A kind of some principles that are applicable to the side direction stake plated construction of steep rocky slope embankment of the above the utility model that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore the corresponding modify being likely utilized every and equivalent, all belong to the scope of the claims that the utility model is applied for.
