Description
Technical Field
The utility model belongs to the technical field of the construction of building bridge is used, concretely relates to is applied to waterproof construction of bridge box girder construction.
Background
The box-section beam bridge refers to a beam bridge with a main beam in a thin-wall closed section form. Long hollow trusses made of steel or concrete are usually used as beams. This makes the bridge light and strong. The bridge constructed by this method is called a box girder bridge.
Waterproofing treatment is needed in the construction of the basement, and if the first concrete layer of the basement needs to be designed into a waterproof structure, the safety of the basement main body building is ensured (the water seepage phenomenon is prevented).
Therefore, based on the above problem, the utility model provides a be applied to waterproof construction of bridge box girder construction.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a be applied to waterproof construction of bridge box girder construction, its reasonable in design, be convenient for construction and with low costs have good leakproofness, water-proof effects after the construction simultaneously, and the practicality is strong.
The technical scheme is as follows: the utility model provides a be applied to waterproof construction of bridge box girder construction, including setting up the first concrete layer on adjacent box girder two sides respectively, the second concrete layer, and set up the polymer waterproofing membrane at first concrete layer outer wall, and set up the supplementary concrete layer that just covers polymer waterproofing membrane on first concrete layer surface, and set up at first concrete layer, the second concrete layer, the eyelet steel sheet net between the cavity that adjacent box girder constitutes, and the symmetry sets up the first main reinforcing bar on eyelet steel sheet net, the second main reinforcing bar, and set up respectively on first main reinforcing bar, a plurality of first arrangement of reinforcement on the second main reinforcing bar, a plurality of second arrangement of reinforcement, and the symmetry sets up on eyelet steel sheet net and is located first main reinforcing bar, the first auxiliary reinforcing bar between the second main reinforcing bar, the second auxiliary reinforcing bar, and set up respectively on first auxiliary reinforcing bar, a plurality of first auxiliary arrangement of reinforcement on the second auxiliary reinforcing bar, And a plurality of second auxiliary reinforcing bars.
This technical scheme's, the first arrangement of reinforcement of a plurality of, a plurality of second arrangement of reinforcement respectively with first main reinforcement, the second main reinforcement become 90 settings between, the first vice arrangement of reinforcement of a plurality of, the vice arrangement of reinforcement of a plurality of second respectively with first vice reinforcement, the vice reinforcement of second become 90 settings between the vice reinforcement of second.
Compared with the prior art, the utility model discloses a be applied to waterproof construction of bridge box girder construction's beneficial effect lies in: the novel waterproof structure is reasonable in design, convenient to construct, low in cost, good in sealing performance and waterproof effect after construction, and high in practicability.
