Abstract
The utility model discloses one for elevated road ramp approach road section Retaining Structures, comprise both sides retaining wall, the inner side of described both sides retaining wall all arranges wall heel slab, it is characterized in that both walls heel slab couples together and forms entirety.The utility model has the advantage of: excavation face during wall-retaining structure construction can be reduced, reduce the destructiveness on Subgrade of old road road surface; Basis links together, can be jointly stressed, is conducive to structure anchorage, structural integrity is good, and structure stress system is more reasonable; When ring road width is little, wall height is higher, concrete and number of steel bars can be saved.
Description
Technical field
The utility model relates to urban elevated road design field, is specifically related to a kind of for elevated road ramp approach road section Retaining Structures.
Background technology
Along with the development in city, urban traffic contacts demand quickly and easily and proposes requirements at the higher level to the key road network in city, and the mode of transportation of long distance continuous stream, becomes the best behavior of urban traffic undoubtedly.Therefore, each metropolis is progressively planned one after another, is transformed and build Expressway Net System.The one that elevated road becomes urban freeway network shell system gradually mainly lays pattern.Elevated ramp is the basic connected mode of a kind of elevated road and ground level road.
Usually, elevated ramp is positioned between ground maneuver track and outside roadway (motor vehicle and the mixed row of bicycle), so the safeguard structure of ring road approach road section generally adopts retaining wall structure pattern.Soil property is weaker, the not abundant area of stone material adopts L-type reinforced concrete retaining wall mostly.When through street be newly-built road or reconstruction road build up the time for a long time, road conditions are poor, excavate will not utilize time, ring road retaining wall can adopt conventional structure pattern, sees Fig. 1.Namely wall heel slab is set, arranged outside toe of wall plate inside retaining wall.Toe point is the center of circle that overturning of retaining wall is rotated, and suitably long toe of wall plate can increase the overturning or slip resistance analysis arm of force and obtain larger resistance to tipping moment; Roomy heel slab can be accepted more soil body weight and form larger resistance to tipping moment.
But when through street is when the rapid transformation of present situation road, existing road road conditions are good, underground utilities are abundant, the toe of wall part intrusion present situation road of ring road retaining wall is more, large to present situation road damage, now conventional ring road retaining wall structure form is also not suitable for, and needs the ring road retaining wall structure taking row.
Utility model content
The purpose of this utility model is to provide a kind of for elevated road ramp approach road section Retaining Structures, reduce the construction and excavation face of ring road approach road section soil-baffling structure, reduce the destruction of road surface, present situation old road and pipeline, greatly saved engineered expense, reduced construction working difficulty.
To achieve these goals, the technical solution of the utility model is as follows: a kind of for elevated road ramp approach road section Retaining Structures, comprise both sides retaining wall, the inner side of described both sides retaining wall all arranges wall heel slab, it is characterized in that both walls heel slab couples together and forms entirety.
Form entirety owing to being coupled together by described retaining wall structure both walls heel slab in the utility model, its stress system is changed, plays jointly stressed effect, therefore can cancel the toe of wall plate of ring road both sides retaining wall.And eliminate the toe of wall plate of retaining wall, just can reduce the excavation face of ring road section road construction, avoid the destruction of present situation road surface structure and underground utilities, effectively utilize present situation structure, reduce construction infection degree.Because retaining wall basis, both sides links together, play jointly stressed effect, be beneficial to structure anchorage, the good integrity of structure, structure stress system is more reasonable.The utility model has the advantage of: excavation face during wall-retaining structure construction can be reduced, reduce the destructiveness on Subgrade of old road road surface; Basis links together, can be jointly stressed, is conducive to structure anchorage, structural integrity is good, and structure stress system is more reasonable; When ring road width is little, wall height is higher, concrete and number of steel bars can be saved.

Detailed description of the invention
Figure comprises: retaining wall 1, toe of wall plate 2, wall heel slab 3, original pipeline 4.
As shown in the figure, the utility model proposes one for elevated road ramp approach road section Retaining Structures, comprise both sides retaining wall 1, the inner side of described both sides retaining wall 1 all arranges wall heel slab 3, it is characterized in that both walls heel slab 3 couples together and forms entirety.The utility model, at the ring road approach road section of elevated road, cancels the toe of wall plate of ring road both sides retaining walls, is coupled together by wall heel slab to be formed overall, and both walls heel slab couples together formation unsplit bed(-)plate.When U-shaped retaining wall width is larger, base plate mid portion can be removed and disconnect with the consumption saving concrete and reinforcing bar, but be connected with binder at spacing intervals, binder spacing regulates at 2 meters according to the length and force request that often save barricade within the scope of 2.5 meters, width is 40 ~ 60 centimetres, base plate hollows out width range and need determine according to the stressed demand of monolithic barricade, hollow out width in the middle of the wide monolithic retaining wall of 8m and be no more than 2.5 meters, as higher in retaining wall height and ring road width is little time do not consider that base plate hollows out.Usually, monolithic retaining wall width be 6 ~ 10m, the most economical when being highly 1.5 ~ 5m.
The feature of this retaining wall structure pattern is: because eliminating the toe of wall plate of retaining wall, reducing the excavation face of ring road section road construction, avoiding the destruction of present situation road surface structure and underground utilities, effectively utilize present situation structure, reduces construction infection degree.Because retaining wall basis, both sides links together, play jointly stressed effect, be beneficial to structure anchorage, the good integrity of structure, structure stress system is more reasonable.Meanwhile, because base plate mid portion is designed to the structural shape of binder, greatly save reinforcing bar and concrete quantity, engineering construction cost is reduced to minimum.When ring road width is less, wall height is higher, economical more obvious.
The retaining wall structure applicability that the utility model proposes is: when existing road carries out rapid transformation, when present situation road structure and underground utilities are utilized, can adopt the monolithic retaining wall structural shape that this excavation face is minimum; In addition, if present situation road is laid with the important pipeline such as gas pipe, petrochemical industry, needs in work progress to ensure certain safe distance etc. in particular cases, also can adopt the monolithic retaining wall structural shape that this excavation face is minimum.The utility model is existing road when carrying out overhead rapid transformation, if the old road underground utilities of newly-built elevated ramp section both sides more, destruction should not be excavated or underground utilities are important, construction safety required distance provides a kind of reasonably solution when high.
