Description
Technical Field
The invention belongs to the technical field of urban beautification construction, and particularly relates to a rapid construction method of a bridge guardrail with a flower bed and a prefabricated external flower bed.
Background
The edges of two sides of the bridge are generally provided with anti-collision guardrails for ensuring the driving safety of the bridge. As the development of cities enters a new stage, the construction of cities has not been limited to the pure functional construction in the past. At present, the requirements for landscapes are becoming higher and higher in the design of urban bridges. In order to improve the landscape effect along the bridge, the most common method is to arrange a flower pond for planting landscape plants outside the anti-collision guardrail and plant the plants for landscape greening in the flower pond.
In the prior art, the construction method of the anti-collision guardrail of the bridge generally adopts a cast-in-place method, namely, after necessary reinforcing steel bars are bound, an inner side template and an outer side template are selected and fixed, and then concrete is poured between the inner side template and the outer side template. And after the concrete is solidified, cured and molded, the previously fixed inner side template and the outer side template are dismantled. The assembling and disassembling of the template in the actual construction process are quite complicated processes, time and labor are consumed, and great inconvenience is brought to the construction of the anti-collision guardrail. And the flower bed is added on the basis of the guardrail, so that the construction complexity is further increased.
The flower bed that sets up in the anticollision barrier outside at present has several kinds of different common forms:
① the first one is a conventional concrete cast-in-place flower bed, which is made of 8-10 cm thick concrete, and the flower bed in this form is the most common at present and is cast in situ like an anti-collision guardrail, and has the advantages of good durability, integrated casting and forming, good landscape effect, capacity of hilling up the flower bed and placing flowerpots, but the disadvantages of the first one are that extra templates and extra steel bars need to be built for the flower bed in the construction process, so that the construction process becomes more complicated, the second one is that the flower bed has a narrow construction space, and the common steel bars need to be arranged, so that the chamfers are more, the templates are complicated, and the construction is more unfavorable, and the third one is that the material is common concrete, and the flower bed structure is heavy (the volume of the part is about 0.35 m)3The weight is about 9.1 kN/m), and is at the outer side of the anti-collision guardrail, the stress on a cantilever panel of the structure is relatively adverse, and the distribution of the supporting and reacting force of the structure is influenced.
② the second is a conventional concrete prefabricated flower bed, the thickness of the concrete is 8-10 cm, the anti-collision guardrail is divided into two parts, one part of the anti-collision guardrail and the flower bed are prefabricated together, then the anti-collision guardrail is hung to a corresponding position on site to be installed, and the anti-collision guardrail and the other part of the anti-collision guardrail are cast together to form a whole through embedded steel bars.
③ the third one is a steel structure flower pool, which is made of steel structure and decorated outside with aluminum-plastic plate, etc. this kind of form is usually used on overpasses, and the weight is light, and the landscape effect is good, but the flower pool of this steel structure is fixed by implanting anchor bolt or steel bar after the anti-collision guard bar is poured, the implanting method is troublesome, and the reliability is low.
