Abstract
A chair type pile sheet wall structure for a slope subgrade helps to effectively solve problems that cantilever reinforcement piles are high outside a high embankment project in a slope area, especially when the edge width of the pile is small in a steep slope, the deformation of the pile top is large, and engineering investment is great and the like. The chair type pile sheet wall structure for the slope subgrade comprises cantilever reinforcement piles (1) arranged longitudinally along the road line at an interval and breast boards (4) fixedly arranged at inner side of the middle of the adjacent cantilever reinforcement piles (1). The dangling and exposed parts of the cantilever reinforcement piles (1) are provided with transverse articulated beams (3). Dangling and exposed parts are rigidly connected with the transverse articulated beams, and connected with embedded reinforcement piles (2) at the backing side of the road line, wherein the embedded reinforcement piles are arranged at an interval. The chair type pile sheet wall structure for the slope subgrade is characterized by being large in rigidity, high in integrity and convenient in construction and economic.
Description
Technical field
The utility model relates to slope course engineering road structure, particularly the road structure of slope railway station or piece of smooth land engineering.
Background technology
China's mountain road engineering fast development in recent years, because mountain area geology orographic condition is relatively poor, when the embankment engineering of building is positioned on the slope, sometimes be difficult to adopt and put the problem that the slope mode of filling solves road, station and piece of smooth land width deficiency, receive the slope and reinforce thereby roadbed or embankment engineering bottom retaining structure need be set.When the filled height of slope embankment engineering is big, it is higher that the cantilever of sloping retaining structure is received in the bottom, it is stressed big and horizontal distortion is very big, it is very high often to be difficult to engineering demands or construction costs, if adopt bridge to pass through, when the filling body wider width (as railway station, the piece of smooth land etc.), the one, construction costs is higher, the 2nd, body bridge inboard, slope may also need to arrange the roadbed retaining structure, and the 3rd, when running into the railway station switch area, all there are big difficulty in bridge engineering design, construction.Therefore, a kind of novel structure of active demand solves the problem that the high embankment engineering in slope exists, and meets environmental protection requirement.
The utility model content
Technical problem to be solved in the utility model provides a kind of slope roadbed chair form stake slab-wall structure, it is higher to reinforce the stake cantilever with the high embankment engineering of the effective solution slope land section outside, particularly problems such as little, the stake top distortion of the safe flap hem width degree of stake greatly and construction investment is big when the slope is steep.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
Roadbed chair form stake slab-wall structure in slope of the present utility model, comprise the cantilever reinforcing stake that arranges along circuit longitudinal separation, and adjacent two cantilevers are reinforced between the stake breast boards that side within it fixedly installs, it is characterized in that: the unsettled exposure that described cantilever is reinforced stake partly arranges rigidly connected horizontal tie-beam with it, and is rigidly connected with the corresponding buried reinforcing stake that arranges at interval in circuit backer side.
The beneficial effects of the utility model are, it is higher to efficiently solve location, slope high embankment engineering outside reinforcing stake cantilever, problems such as particularly the safe flap hem width degree of stake is little when the slope is steep, the distortion of stake top is big and construction investment is big, this structure has that the rigidity of structure is big, good integrity, easy construction, economic dispatch characteristics, and compliance with environmental protection requirements, have wide popularizing application prospect.
Description of drawings
This manual comprises as next width of cloth accompanying drawing:
Fig. 1 is the schematic cross-sectional view of the utility model slope roadbed chair form stake slab-wall structure;
Member spare shown in the figure, toponym and corresponding mark: cantilever is reinforced stake 1, buried reinforcing stake 2, horizontal tie-beam 3, breast boards 4, bearing plate 5, filling body 6.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, roadbed chair form stake slab-wall structure in slope of the present utility model, comprise the cantilever reinforcing stake 1 that arranges along circuit longitudinal separation, and adjacent two cantilevers are reinforced between the stake 1 breast boards 4 that side within it fixedly installs, the unsettled exposure that described cantilever is reinforced stake 1 partly arranges rigidly connected horizontal tie-beam 3 with it, and is rigidly connected with the corresponding buried reinforcing stake 2 that arranges at interval in circuit backer side.The part of horizontal power of utilizing horizontal tie-beam 3 that cantilever is reinforced stake 1 passes to buried reinforcing stake, reduce its horizontal distortion and reduce its stressed cantilever height, it is higher to have solved location, slope high embankment engineering outside reinforcing stake cantilever effectively, problems such as particularly the safe flap hem width degree of stake is little when the slope is steep, the distortion of stake top is big and construction investment is big, this structure has that the rigidity of structure is big, good integrity, easy construction, economic dispatch characteristics, therefore has wide popularizing application prospect.
With reference to Fig. 1, can bearing plate 5 be set at the top of horizontal tie-beam 3, filling body 6 fills on bearing plate 5.Utilize bearing plate 5 to bear other external load of filling body 6 and top on it, can make its underpart exist part unsettled, be conducive to improve the stress condition that cantilever is reinforced stake 1.Utilize breast boards 4 filling body 6 of blocking, when adopting bearing plate 5, laterally tie-beam 3 bottom breast boardss can not arrange.
The spacing that described cantilever is reinforced stake 1 and corresponding buried reinforcing stake 2 with it is generally 5～7m.Because laterally tie-beam 3 suffered bending moments are bigger, can adopt prestressed reinforced concrete to build, two ends are connected with cantilever reinforcing stake 1 and the buried reinforcing bar of reinforcing stake 2 should strengthen design.
Some principles of the above the utility model slope roadbed chair form stake slab-wall structure that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
