The box culvert is a culvert with a body constructed by reinforced concrete box-shaped pipe joints, and consists of one or more square or rectangular sections for passing pedestrians and vehicles. After some time after construction, damage is likely to occur, and repair is required. At present, when repairing a box culvert, a layer of polymer plastic plate is fixed on the outermost layer, usually, holes are punched on the surface of the plate, then bolts are used for fixing, but the bolts are exposed in natural environment for a long time and are easy to corrode, so that the service life and safety of the plate installation are affected.
In order to solve the problems, the utility model provides a fixing structure of a box culvert repair liner, which aims to solve the problem that a fixing bolt is easy to corrode when exposed in the natural environment for a long time ， Fig. 1 to 2 are schematic views illustrating an embodiment of a fixing structure of a box culvert repairing liner according to the present utility model.
Referring to fig. 1 to 2, the utility model provides a fixing structure 1000 for repairing a liner of a box culvert, which comprises an impermeable plate 1, a fixing bolt 2 and a cover plate 3, wherein the impermeable plate 1 is provided with a mounting groove 11, the bottom wall of the mounting groove 11 is penetrated with a mounting hole, the fixing bolt 2 is used for fixing the impermeable plate 1, the fixing bolt 2 is penetrated in the mounting hole, and the cover plate 3 is covered on the mounting groove 11 to seal the mounting groove 11.
In the technical scheme of the utility model, the anti-seepage plate 1 is provided with the mounting groove 11 for placing the nuts of the fixing bolts 2, and the mounting groove 11 is sealed by the cover plate 3, so that the nuts of the fixing bolts 2 are prevented from being corroded due to exposure to the natural environment.
It will be appreciated that the bottom wall of the mounting groove 11 and the nut of the fixing bolt 2 are not on the same plane, and the nut of the fixing bolt 2 needs to be avoided when the cover plate 3 is placed, for which purpose, in an embodiment of the utility model, the end surface of the cover plate 3 facing the bottom wall of the mounting groove 11 is provided with an avoiding groove 31 for avoiding the nut of the fixing bolt 2.
