Technical field
The utility model relates to a kind of cable trough and cover plate thereof, especially a kind of cable trough and cover plate thereof that is applicable to flood-discharge atomizing district and heavy showers area.
Background technology
The cables such as the power supply supply between building, signal transmission, communication, the cable that project scale is little is thinner, less, can adopt electric pole to support, but the cable between the hydroelectric project building is thicker, many, heavier, the employing electric pole is dangerous, usually adopts the cable trough of excavation to lay.Cable trough is the underground designated lane of cabling on engineering, comprise base plate, sidewall and cover plate, backplane is generally excavated according to certain gradient along landform, because maintenance needs, cover plate requires and can open, cover plate generally is supported on sidewall, and the crane span structure of cabling is by dowel or be bolted on sidewall.The cable trough base plate is generally comparatively smooth-going, and cover plate also adopts dull and stereotyped, simple in structure usually.
But when laying above-mentioned normal cable ditch in the flood-discharge atomizing district, surface water easily flows into cable trough from the gap between cover plate, will have following point: the first, and a large amount of insulated streams enter cable trough easily destroy by rush of water cable and crane span structure; The second, long-term moist environment is serious to the corrosion failure of cable trough concrete and crane span structure.
How avoiding a large amount of insulated streams to enter cable trough, and reduce as far as possible rainwater and invade cable trough, is the problem that needs solve.
The utility model content
Easily flow into the deficiency of cable trough in order to overcome existing cable ditch surface water, technical problem to be solved in the utility model is to provide a kind of cable trough and cover plate thereof of avoiding a large amount of insulated streams to enter.
The technical scheme that its technical problem that solves the utility model adopts is: cable channel cover plate, be included as the cover board body of slab construction, vertical two ends of described cover board body are respectively arranged with faulting of slab ends and lower faulting of slab ends, the shape of the shape of upper faulting of slab ends and lower faulting of slab ends cooperatively interacts, and lower faulting of slab ends and cover board body adjacent position has the catchment recess that lateral direction penetrating arranges.
Described cover plate is prefabricated reinforced concrete structure.
Described upper faulting of slab ends is the consistent slab construction of longitudinal length with lower faulting of slab ends.
Described upper faulting of slab ends and lower faulting of slab ends are mutually corresponding concaveconvex structure.
Adopt the cable trough of above-mentioned cable channel cover plate, the base plate, sidewall and the cover plate that comprise cable trough, described sidewall is above ground level, cover plate covers on sidewall, described cover plate is included as the cover board body of slab construction, vertical two ends of cover board body are respectively arranged with faulting of slab ends and lower faulting of slab ends, the shape of the shape of upper faulting of slab ends and lower faulting of slab ends cooperatively interacts, the adjacent position of lower faulting of slab ends and cover board body is provided with the catchment recess that lateral direction penetrating arranges, and mutually overlaps by upper faulting of slab ends separately, lower faulting of slab ends between adjacent cover plate.
The sidewall of described base plate and its both sides is integrated the xoncrete structure of building.
The beneficial effects of the utility model are: simple and easy to do, successful, especially be suitable for flood-discharge atomizing district and heavy showers the area.

Be labeled as 1-base plate, 2-sidewall, 3-cover plate, 4-ground in figure, the horizontal arrangement of reinforcement of 11-cover plate, 12-cover plate longitudinal reinforcement, 30-cover board body, the upper faulting of slab ends of 31-, faulting of slab ends under 32-, the 33-catchment recess, 34-cover plate gap, 40-above-ground route, the overhead height of H-sidewall, the longitudinal length of L-faulting of slab ends.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As Fig. 1~shown in Figure 6, cable channel cover plate of the present utility model, be included as the cover board body 30 of slab construction, vertical two ends of described cover board body 30 are respectively arranged with upper faulting of slab ends 31 and the lower faulting of slab ends 32 that cooperatively interacts, the adjacent position of lower faulting of slab ends 32 and cover board body 30 has the catchment recess 33 that lateral direction penetrating arranges, efflux from groove two ends after the surface water that flows down along cover plate 3 is collected by catchment recess 33, the surface water that enters cable trough reduces in a large number, thereby has extended the useful life of cable trough.
Described cover plate 3 is prefabricated reinforced concrete structure, guarantees the globality of cover plate 3, and only need to do simple transformation to existing mold when prefabricated cover plate 3 can obtain corresponding faulting of slab ends and sink structure, and demoulding difficulty does not increase substantially, and the installation of cover plate 3 is convenient too.
As Fig. 1~shown in Figure 5, described upper faulting of slab ends 31 can be the consistent slab construction of longitudinal length with lower faulting of slab ends 32, in general recommendations this moment, the thickness of faulting of slab ends 31 and lower faulting of slab ends 32 is 1/2 of cover plate 3 thickness, and upper and lower faulting of slab ends makes also has certain cross spacing function between its adjacent cover plate.
As shown in Figure 6, described upper faulting of slab ends 31 and lower faulting of slab ends 32 are mutually corresponding concaveconvex structure, catchment recess 33 can be considered as the part of lower faulting of slab ends 32, and the upper and lower faulting of slab ends of such concaveconvex structure makes also has better cross spacing function between its adjacent cover plate, prevent the horizontal sliding of cover plate.
As Fig. 1~shown in Figure 6; Cable trough of the present utility model comprises the base plate 1 of cable trough; Sidewall 2 and cover plate 3; Described sidewall 2 above ground level 4; Cover plate 3 covers on sidewall 2; Cover plate 3 adopts above-mentioned cable channel cover plate of the present utility model; Pass through upper faulting of slab ends 31 separately between adjacent cover plate 3; Lower faulting of slab ends 32 overlaps mutually; To no longer include the gap of direct and cable trough internal communication between cover plate 3; Secondly; Even at upper faulting of slab ends 31; Still there is the gap in lower faulting of slab ends 32; But surface water also more easily flows to catchment recess 33 rather than flows in cable trough; Therefore; The surface water that enters cable trough reduces in a large number; Thereby extended the useful life of cable trough.
Further that for guaranteeing the stabilized structure of base plate 1 and sidewall, best described base plate 1 is integrated the xoncrete structure of building with the sidewall 2 of its both sides.
The cable trough and the cover plate thereof that design like this have the following advantages:
The first, the cable protection performance is good.Cable trough sidewall 2 is above the ground level, and avoids large flow surface water to flow into the cable trough cable that destroys by rush of water, and the protective value of cable is had obvious superiority.
The second, structure durability can be good.The utility model cable trough at utmost avoids surface water and rainwater to flow into, and has reduced oxidation and the erosion damage of water to concrete and crane span structure, has strengthened the durability of structure.
The 3rd, making, construction, maintenance and pedestrian are convenient.Cable channel cover plate is above the ground level, and is interconnected, and all can be used as the walkway during daily and flood discharge heavy showers; Simultaneously, the prefabricated reinforced concrete cover plate all provides convenience preferably at aspects such as processing and fabricating, carrying construction and ordinary maintenances.
