Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in further detail.
Shown in Figure 1, this utility model embodiment provides a kind of for clad steel truss bridge Drainage system, including some central drainage mouths 1 and some direct discharge outlet 9, see Fig. 2 and Shown in Fig. 3, central drainage mouth 1 is distributed on upper deck of bridge 2 and lower floor's bridge floor 3 of bridge, Directly discharge outlet 9 is distributed in the upper deck of bridge 2 of bridge, and central drainage mouth 1 and direct draining Mouth 9 interlaced arrangement, the end face of central drainage mouth 1 is less than the height of corresponding bridge floor, direct draining The end face of mouth 9 is higher than bridge floor height, and central drainage mouth 1 is all provided with the top of direct discharge outlet 9 It is equipped with trash rack 11.
Collection pipe 4 is concentrated on one upper strata, and upper strata concentrates collection pipe 4 to be positioned at upper deck of bridge 2 and lower floor Between bridge floor 3, and it is positioned at the central drainage mouth 1 of upper deck of bridge 2 by a central drainage pipe 5 Collection pipe 4 is concentrated to connect with upper strata.
One lower floor concentrates collection pipe 6, and lower floor concentrates collection pipe 6 to be positioned at the lower section of lower floor's bridge floor 3, And it is positioned at the central drainage mouth 1 of lower floor's bridge floor 3 by central drainage pipe 5 and lower floor's concentration charge for remittance Pipe 6 connects.
Upper strata is concentrated collection pipe 4 and lower floor to concentrate between collection pipe 6 and is provided with some in line charges for remittance Pipe 8, upper strata concentrates collection pipe 4 to concentrate collection pipe 6 to be connected by line collection pipe 8 with lower floor Logical, and directly discharge outlet 9 concentrates collection pipe 6 to be connected by line overflow pipe 10 with lower floor.
One collection device 7, upper strata concentrates collection pipe 4, lower floor to concentrate collection pipe 6, in line remittance Water pipe 8 all converges into collection device 7.
Water on bridge can be passed sequentially through central drainage pipe 5 and concentrate remittance by central drainage mouth 1 In water pipe 4 collection device 7, it is to avoid directly drain into polluted-water in waters, compare environmental protection.
And upper strata concentration collection pipe 4 and lower floor concentrate and are provided with some in line remittances between collection pipe 6 Water pipe 8, has certain differential water pressures between top and the bottom of in line collection pipe 8, and then can Form impulse force and wash away dirt, it is to avoid dirt blocks corresponding pipeline.
When rainwater is bigger, owing to collection pipe 4 is concentrated on quantity, the upper strata of central drainage mouth 1 Space is the most limited, it is difficult to discharged by the rainwater on bridge floor in time, rainwater after bridge floor collects, meeting The load causing bridge is overweight, in this utility model, owing to direct discharge outlet 9 is higher than bridge floor, When rainwater did not had direct discharge outlet 9, it is possible to by direct discharge outlet 9 by rainwater via in line Overflow pipe 10 enters lower floor and concentrates in collection pipe 6, and then can speed up the discharge of rainwater, subtracts The load of the light excessive bridge caused of upper deck of bridge 2 rainwater is overweight.
And the drainage system in this utility model can be used for monolayer bridge, monolayer bridge only needs Upper deck of bridge 2 to arrange some central drainage mouths 1 and some direct discharge outlet 9, then Enter upper strata by corresponding central drainage pipe 5 and concentrate in collection pipe 4, direct discharge outlet 9 Corresponding central drainage pipe 5 enters upper strata and concentrates in collection pipe 4.
In actual use, central drainage mouth 1 be arranged on car shape to and footpath (maintaining roadway) Both sides, and along vertical bridge to setting.
This utility model is not limited to above-mentioned embodiment, for the ordinary skill of the art For personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvement And retouching, within these improvements and modifications are also considered as protection domain of the present utility model.This explanation The content not being described in detail in book belongs to prior art known to professional and technical personnel in the field.
