Embodiment Construction
[0045] Attached to the following Figure 1-12 This application will be described in further detail.
[0046] The embodiment of the present application discloses a construction method of a bridge anti-collision retaining wall.
[0047] A method for constructing a bridge anti-collision retaining wall, the steps are as follows:
[0048] Prefab:
[0049] The bridge structure 1 and the prefabricated crash wall 2 are prefabricated.
[0050] refer to figure 1 , the bridge structure 1 is a box girder, and both sides of the bridge structure 1 in the length direction are reserved with rectangular long-striped reserved grooves 11, the reserved grooves 11 are opened on the top wall of the bridge structure 1, and the length of the reserved grooves 11 The direction is the same as the length direction of the bridge structure 1 , and the inner walls on both sides of the reserved groove 11 in the length direction protrude from the extension bars 111 .
[0051] refer to figure 2 , the pr...

The invention relates to the field of bridge construction, in particular to a bridge anti-collision protective wall construction method which comprises the steps that a bridge structure and a prefabricated anti-collision wall are manufactured in advance; the bridge structure which is prefabricated in advance is built; the multiple sections of prefabricated anti-collision walls are installed on the bridge structure, and the multiple sections of prefabricated anti-collision walls are arranged at intervals; a pouring formwork is built between every two adjacent sections of prefabricated anti-collision walls, and the space between every two adjacent sections of prefabricated anti-collision walls is surrounded by the corresponding pouring formwork; concrete is poured into the pouring formwork; and after the poured concrete is solidified to a specified degree, the pouring formwork is removed. The construction method has the effect of reducing the workload of formwork construction and disassembly.
Description
technical field [0001] The present application relates to the field of bridge construction, and in particular, to a method for constructing an anti-collision retaining wall for a bridge. Background technique [0002] In order to make the operation of vehicles on the bridge safer, the bridge structure will be provided with crash barriers. [0003] In the related art, the bridge anti-collision retaining wall is formed by building templates and then pouring concrete to solidify. Because the bridge anti-collision retaining wall is long, the construction personnel need to build a large number of templates. After the concrete is solidified, all the templates need to be removed. [0004] A large number of installation and removal of formwork work, increased the workload of construction workers, but also extended the construction time. SUMMARY OF THE INVENTION [0005] In order to reduce the workload of building and dismantling the formwork, the present application provides a met...
