Abstract
The utility model discloses a cable pit waterproof cover plate structure belongs to cable pit waterproof technical field, including cable pit and apron, the apron lid is on the cable pit, cable pit upper end both sides limit is equipped with the capillary, apron both sides limit is equipped with the boss that corresponds with the capillary, is equipped with upper groove and low groove respectively at apron both ends head simultaneously, but the lock is connected each other of upper groove and low groove. This technical scheme carries out structural improvement through the gap position to intaking easily between apron and the cable pit and between apron and the apron, the side of apron is established defences the basin and is sealed, simultaneously with the junction between the adjacent apron waterproof through the overlap joint, the goodness of fit between apron and the cable pit and between apron and the apron has been strengthened, can effectively prevent rivers to go into in the cable pit, keep the cable pit dry, reduce because the corruption to the cable support and the harm to the cable in the rivers ditch, be favorable to the safety and stability operation of power station.
Description
Technical field
The utility model belongs to cable trough waterproof technique field, relates to cable trench cover structure, especially relates to a kind of cable trough waterproof cover structure.
Background technology
The power cable, control cables, telecommunication cable etc. in hydroelectric station, cable laying generally by cable testing bridge, cable shaft, cable trough, wear pipe laying etc.During by cable trough cabling, as shown in Figure 1, generally first on roadbed 4, built cable trough 1, then installing cables support 3 in cable trough 1, covers cover plate 2 to cable trough after cable laying is on cable bearer 3.The drawback that this mode exists is adjacent two cover plates 2 contact position, because the cover plate 2 of precast concrete is processed more coarse, contact-making surface coincide bad, and cover plate 2 coincide also bad with the cable trough 1 of building, water is easily caused to flow into cable trough 1, be corrosion cable bearer on the one hand, also make cable for a long time as moist environment on the other hand, be unfavorable for power plant safety stable operation.
At present for solution cable trough water inlet problem, there is the evolutionary approach of some cable channel cover plates, if application number is 201320302284.0 disclose a kind of cable trough and cover plate thereof, by arranging horizontal water leg, water being derived, overlapped by faulting of slab ends between cover plate, strengthen cover plate degree of agreement; Application number is 201420267678.1 disclose the rainproof cable channel cover plate of a kind of transformer station, is overlapped between cover plate by faulting of slab ends, and arranges concavo-convex and strengthen degree of agreement; Application number is that 201420563423.X discloses a kind of cable trough waterproof cover structure, by N-shaped inserting groove, strengthens the degree of agreement between every block cover plate.The problem of these schemes is, it all only considers the degree of agreement strengthened between cover plate and cover plate, do not consider the degree of agreement between cover plate and cable trough edge, the problem causing the gap between cover plate and cable trough often to have water to infiltrate cable trough is not resolved.
Utility model content
In order to solve the problem, the utility model provides a kind of cable trough waterproof cover structure, thus reaches the effect preventing cable channel cover plate four side from intaking.
The utility model is achieved by following technical solution.
A kind of cable trough waterproof cover structure, comprise cable trough and cover plate, described cover plate covers on cable trough, described cable trough upper end dual-side is provided with capillary groove, described cover plate dual-side is provided with the boss corresponding with capillary groove, be respectively equipped with upper groove and low groove in cover plate two ends, described upper groove and low groove can be fastened and connected mutually simultaneously.
Further, sealing strip a is provided with in described capillary groove.
Further, sealing strip b is provided with in described upper groove.
Further, described cover plate adopts armored concrete to make, and the bulge-structure lower surface of boss lower surface and low groove end polishes flat.
Further, described cover plate cross section top margin is arc.
Further, in the middle of described cover plate cross section, the thickness difference of thickness and edge thinnest part is 4 ~ 6mm.
Further, described cover plate is higher than roadbed about 4 ~ 6mm.
The beneficial effects of the utility model are:
A kind of cable trough waterproof cover structure described in the utility model, by carrying out architecture advances to the gap position of easily intaking between cover plate and cable trough and between cover plate and cover plate, tank of being set up defences the side of cover plate seals, waterproof is carried out by overlap joint in junction between adjacent cover plate simultaneously, strengthen the goodness of fit between cover plate and cable trough and between cover plate and cover plate, water can be effectively stoped to flow in cable trough, keep cable trough dry, reduce because water flows into the corrosion to cable bearer and the harm to cable in ditch, be conducive to the safe and stable operation in power station.

In figure: 1-cable trough, 101-capillary groove, 102-sealing strip a, 2-cover plate, 201-boss, 202-upper groove, 203-low groove, 204-sealing strip b, 3-cable bearer, 4-roadbed.
Embodiment
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in figures 1-4, a kind of cable trough waterproof cover structure described in the utility model, comprise cable trough 1 and cover plate 2, described cover plate 2 adopts armored concrete to make, cover on cable trough 1, cover plate 2 cross section top margin is arc, and to avoid ponding on cover plate 2 end face, in the middle of cross section, the thickness difference of thickness and edge thinnest part is 4 ~ 6mm; In addition, higher than roadbed about 4 ~ 6mm, for sinking space reserved by cover plate 2, there is the gap place ponding of sinking afterwards and between roadbed 4 to avoid cover plate 2 in cover plate 2.
Described cable trough 1 upper end dual-side is provided with capillary groove 101, is provided with sealing strip a102, to ensure sealing effectiveness in capillary groove 101; Described cover plate 2 dual-side is provided with the boss 201 corresponding with capillary groove 101, and boss 201 lower surface polishes flat, and fits well with the sealing strip a102 in capillary groove 101; Be respectively equipped with upper groove 202 and low groove 203 in cover plate 2 two ends simultaneously, sealing strip b204 is provided with in upper groove 202, the bulge-structure lower surface of low groove 203 end polishes flat, described upper groove 202 can be fastened and connected mutually with low groove 203, after fastening, the bulge-structure of low groove 203 end coordinates with upper groove 202, fits well with sealing strip b204.
