Embodiment 1
[0017] The overpass concrete external hanging cantilever type flower bed of the present embodiment is as follows: figure 1 As shown, the reinforced concrete rib 2 extends upwards from the edge of the width direction of the horizontal bridge deck 1 . The top of the reinforced concrete sidewall 2 fixes the anti-collision guardrail 4 through pre-buried foundation feet, and the bottom extends outward and upward to form an arc-shaped outer altar edge 5. The outer circular arc surface of the outer altar edge 5 extends to cover the edge end surface of the horizontal bridge deck 1, which not only makes the overpass more beautiful in appearance, but also helps to enhance its strength. Between the outer altar edge 5 and the reinforced concrete retaining edge 2, an upper large lower altar cavity 6 with a cross-section approximately trapezoidal is formed. Because it is made of concrete, it is integrated with the bridge, and the overall structure is good. At the same time, the function of...

The invention relates to an overpass concrete outside-hanged cantilever type flower bed, simultaneously relates to a construction method thereof, which and belongs to the technical field of building construction. The flower bed comprises a reinforced concrete flange extending upwards from the edge of the horizontal bridge width direction. The bottom of the reinforced concrete flange further extends outwards and upwards to form an arc-shaped outer bed edge. A bed cavity with big end up is arranged between the outer bed edge and the flange, the section of the bed cavity is similar to a trapezoidal shape, and a broken stone cushion layer is overlaid at the bottom of the bed cavity. A horizontal water pipe extending along the length direction of the bed cavity is supported on the upper surface of the broken stone cushion layer, and penetrating water drainage pipes penetrating from the upper surface of the broken stone cushion layer of the bed cavity to a bridge floor water drainage pipe are distributed on the concrete flange at intervals. The construction method comprises arranging supports, assembling reinforcing steel bars, installing pipelines, constructing molds, pouring concrete, clearing and completing. The overpass concrete outside-hanged cantilever type flower bed has the advantages of greening bridges, beautifying cities and occupying little area, and simultaneously has an effect of enhancing strength of overpasses and preventing people from knocking at walls.
Description
technical field [0001] The invention relates to a partial structure of an urban overpass, in particular to a cantilever-type flower bed with a concrete overpass and a construction method thereof, belonging to the technical field of building construction. Background technique [0002] According to the applicant's understanding, most of the flower beds on the existing urban overpass adopt the structure that the hanging box is connected with the anti-collision wall bar, and then the greening flower box is put into it. This structure has many problems such as cracks between the connecting support of the external hanging box and the cement, some fixing bolts are easily corroded, rusted and loosened, the shell of the plastic container is brittle and damaged, and the water supply and drainage facilities are not perfect. [0003] The Chinese patent application with the application number CN201010137605.7 discloses an assembled three-dimensional flower bed and a manufacturing method ...
