Abstract
The utility model relates to a groove-shaped embankment structure, and aims to solve the problems that the conventional fill section embankment projects mainly adopt trapezoidal embankments which are large in fill quantity, wide in occupied land width, and higher in retaining structure foundation bearing capacity. The groove-shaped embankment structure adopts the structure that a reinforced concrete baseplate is arranged below a ground line; vertical reinforced concrete side walls are arranged at both ends of the reinforced concrete baseplate; the reinforced concrete baseplate and the reinforced concrete side walls form a groove-shaped structure; filling materials are arranged in the groove-shaped structure; geogrids are arranged in the filling material; a formation base layer is arranged on the filling materials; protection shoulders are arranged on two sides of the filling materials; weep holes are formed in the bottoms of the protection shoulders and the reinforced concrete side walls. The groove-shaped embankment structure has the advantages that soil resources are effectively saved; the stress of the foundation is uniform; subgrade settlement is easy to control; the structural integrity is good; the masonry quantity is reduced; the groove-shaped embankment structure can be widely applied to the design of railways, highways and peripheral urban roads, which are limited by terrain features.
Description
Technical field
the utility model relates to the embankment structure in a kind of road construction project, is specifically related to a kind of grooved embankment structure.
Background technology
Plains region landform is smooth, open, and soil is fertile, and the overwhelming majority is high-yielding grain fields, and villages and small towns are intensive, and road is staggered.Be subject to the control of grade separation height, subgrade construction passes through mainly with embankment mode, generally adopts trapezoidal embankment form, and fill yard is large, takes up an area width wide, and removal expense is higher; Adopt retaining structure higher to ground requirement for bearing capacity, engineering cost is large.
Summary of the invention
The purpose of this utility model is to provide a kind of grooved embankment structure that can reduce amount of fill, reduce floor space.
The technical scheme that the utility model adopts is:
A kind of grooved embankment structure, is characterized in that:
Under above-ground route, reinforced concrete floor is set, reinforced concrete floor two ends all arrange vertical steel concrete side wall, and reinforced concrete floor and two ends steel concrete side wall form trench structure, and filler is set in trench structure, are surface layer of subgrade bed on filler.
Filler successively fills, and end face is arranged to downward-sloping weathering to both sides from center line, and the gradient is 2 ~ 4%;
Between each layer of filler, geo-grid is set.
Downward-sloping weathering is arranged on surface layer of subgrade bed surface to both sides from center line, the gradient is 2 ~ 4%;
The shoulder protector that the gradient is 1:1 is arranged in surface layer of subgrade bed both sides, and shoulder protector bottom surface is provided with protruding, downward-sloping spilled water hole, and the spilled water hole gradient is 4%.
The bottom of steel concrete side wall is provided with protruding, downward-sloping spilled water hole, and the spilled water hole gradient is 4%;
The port that is positioned at filler one side of spilled water hole is provided with infiltration sheet material.
Steel concrete side wall top is provided with guard rail.
The utlity model has following advantage:
1, grooved embankment structure, under the prerequisite of assurance stability of slope, can effectively economize the land resource, and can be widely used in the road design of the railway, highway and the cities and towns periphery that are subject to terrain and its features restriction.
2, grooved embankment structure base plate and both sides abutment wall are connected to become an entirety, and structural stress state is good.
3, trench structure embankment base plate can guarantee that roadbed substrate is stressed evenly, and scalable to bearing capacity of foundation soil, subgrade settlement is easily controlled.
4, grooved embankment structure good integrity, roadbed body has good stability, and can effectively prevent embankment slippage or unstability.
5, trench structure embankment form and trapezoidal fill section in the past or both sides divide that to offer retaining engineering different, and structural entity is stressed more reasonable, can reduce quantity of masonry.
6, trench structure embankment side plate both sides can be in conjunction with surrounding environment, and the suitable flowers, plants and trees of planting, reaches the object that greening side slope and surrounding environment are harmonious, can in the subgrade construction such as city suburbs, Scenic Spots, promote the use of.
Accompanying drawing explanation
Fig. 1 is the utility model structure section figure.
In figure, 1-reinforced concrete floor, 2-steel concrete side wall, 3-filler, 4-geo-grid, 5-surface layer of subgrade bed, 6-shoulder protector, 7-guard rail, 8-spilled water hole, the 9-sheet material that seeps water.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in detail.
A kind of grooved embankment structure that the utility model relates to, reinforced concrete floor 1 is set under above-ground route, reinforced concrete floor 1 two ends are provided with vertical steel concrete side wall 2, and reinforced concrete floor 1 forms trench structure with two ends steel concrete side wall 2.Steel concrete side wall 2 tops are provided with guard rail 7.
The bottom of steel concrete side wall 2 is provided with protruding, downward-sloping spilled water hole 8, and spilled water hole 8 gradients are 4%.The port that is positioned at filler 3 one sides of spilled water hole 8 is provided with infiltration sheet material 9.
It is cited that content of the present utility model is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model manual, is claim of the present utility model and contains.
