Description

Box culvert structure for landscape lake Technical Field The utility model relates to the water conservancy field technology, in particular to a box culvert structure for landscape lakes. Background In landscape lake design, box culverts (rectangular section culverts) are common drainage or water delivery structures, and are mainly used for controlling water level, communicating water systems or coping with heavy rain drainage. The box culvert generally controls the water level through the flood discharge gate installed in the box culvert, when the flood discharge gate needs to be overhauled, the water level needs to be reduced below the bottom end of the flood discharge gate, the personnel safety overhaul can be guaranteed in a water-free state, but when the operation of a lake landscape and a mountain village is carried out, the landscape lake needs to maintain the normal water level for a long time, and water needs to be supplemented when the water level is reduced, so that the water cost and the electric charge brought by the operation of a pump station can be increased each time the flood discharge gate is overhauled. Disclosure of utility model In view of the above, the main object of the present utility model is to provide a box culvert structure for a landscape lake, which solves the problems that when a flood discharge gate needs to be overhauled, water level needs to be reduced below the bottom end of the flood discharge gate, no water state is needed to ensure personnel to be overhauled safely, but when a lake landscape and a mountain village operate, the landscape lake needs to maintain a landscape normal water level for a long time, and water needs to be replenished when the water level is reduced, which also causes that water cost and electricity cost brought by pump station operation are increased each time the flood discharge gate overhauls. The technical scheme is that the box culvert structure for the landscape lake comprises a culvert and a flood discharging gate which is arranged at the outlet end of the culvert and can be opened, wherein an overflow weir is arranged in the middle of the inlet end of the culvert, symmetrical concave plates are arranged on the side wall of the overflow weir and the inner wall of the culvert, pluggable water blocking plates are arranged in the concave plates, and the upper ends of the water blocking plates are higher than the upper ends of the overflow weirs. Further, the top of the culvert is provided with an overhaul channel, and one side of the overhaul channel corresponds to the back water surface of the water-blocking plate. Further, the upper end of the water blocking plate is provided with a lifting lug, the upper end face of the culvert is provided with a driving piece, and the output end of the driving piece extends to the inner cavity of the culvert to be connected with the lifting lug. Further, water stop rubber is arranged between the concave plate and the water stop plate. Further, the two side walls of the concave plate are respectively provided with a bolt, one end of each bolt extends to the inner cavity of the concave plate, and moves towards the inner cavity of the concave plate along with one end of each bolt, and the inner wall of the concave plate extrudes water-stopping rubber. Further, the method comprises the steps of, a middle baffle plate is arranged in the middle of the inner cavity of the culvert, the flood discharge gate is arranged between the side wall of the middle partition plate and the inner wall of the culvert. Further, a first distance for a plurality of persons to pass through is arranged between one side of the middle partition plate corresponding to the overflow weir and the back surface of the overflow weir. Further, a fish blocking net is arranged beside the upstream surface of the overflow weir, and the fish blocking net, the concave plate and the water blocking plate are all made of stainless steel. Further, one side of the top of the culvert is provided with a kerf, the kerf is positioned above the overflow weir and the water blocking plate, and a cover plate is paved on the kerf. Further, the access channel is located between the cover plate and the opposite side edge of the culvert. Compared with the prior art, the utility model has obvious advantages and beneficial effects, in particular, according to the technical scheme, the lake water entering the outside of the culvert water inlet is shielded by the cooperation of the overflow weir and the water blocking plate, so that when the lake water outside the culvert water inlet is higher than the bottom end of the culvert, maintenance personnel can enter the culvert to maintain the flood discharge gate in the culvert, and the maintenance has no influence on the lake water level. In order to more clearly illustrate the structural features and efficacy of the present utility model, the present utility model will be described in detail below with reference to the ac
