Furthermore, a motor vehicle lane is arranged on the middle bottom plate of the U-shaped groove roadbed, and non-motor vehicle lanes are respectively arranged on the connecting bottom plates on the two sides.
Compared with the prior art, the utility model have following advantage and effect:
1. the utility model vertically installs the connecting bottom plates extending outwards on the top of the lower side walls at the two sides of the U-shaped groove roadbed respectively, the upper side walls are arranged on the connecting bottom plates respectively, and the upper side walls are connected with the road surface section; wherein, on the one hand, the roadbed structure that bottom plate and upper portion side wall constitute is connected to both sides can be used to pedestrian and non-motor vehicles's the current to alleviate road surface traffic pressure, on the other hand, the setting of bottom plate and both sides upper portion side wall is connected to both sides, can effectively avoid when the road width broad, and U type groove roadbed transversely excavates the size too big, has reduced the influence of groundwater buoyancy and outside soil and water pressure to U type groove roadbed structural stability and security then to a certain extent.
2. Road surface changeover portion U type groove roadbed structure compare with current conventional U type groove roadbed structure, when the cutting digs deeply great, can obviously reduce the earthwork excavation volume, just U type groove roadbed and both sides are connected bottom plate and both sides upper portion side wall and are the shaping of pouring as an organic whole, when practical application, the wholeness is good, the engineering volume is little, maneuverability is strong.
3. To sum up, road surface changeover portion U type groove roadbed structure have better wholeness and stability, can reduce the excavation of earth and rockwork in a large number, can realize the effect that people's car reposition of redundant personnel, machine non-branch were walked, have fine popularization and application and worth.
