Abstract
The invention discloses a cable trench seal cover plate and belongs to the field of a cable trench waterproof technology. The cable trench seal cover plate comprises a cable trench and a cover plate. The cover plate covers the cable trench. Two sides of the upper end of the cable trench are provided with waterproof grooves. Two sides of the cover plate are equipped with bosses corresponding to the waterproof grooves. Meanwhile, two ends of the cover plate are respectively provided with an upper groove and a lower groove. The upper groove and the lower groove can be in snap-fit connection with each other. According to the technical scheme, easily-waterlogged gap positions between a cover plate and a cable trench and between a cover plate and a cover plate undergo structure improvement. The side surface of the cover plate is provided with the waterproof grooves for sealing, and junction of adjacent cover plates is sealed for watertightness by lap joint. Thus, anastomosis degree between a cover plate and a cable trench and between a cover plate and a cover plate is enhanced. Water can be effectively prevented from flowing into the cable trench so as to keep the cable trench dry. Corrosion of water flowing into the cable trench to a cable holder and harm of the water to cables are reduced. The cable trench seal cover plate is beneficial to safe and stable operation of a power station.
Description
Technical field
The invention belongs to cable trough waterproof technique field, relate to cable trench cover structure, especially relate to a kind of cable trough seal cover board.
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 seal cover board, 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.
Summary of the invention
In order to solve the problem, the invention provides a kind of cable trough seal cover board, thus reaching the effect preventing cable channel cover plate four side from intaking.
The present invention is achieved by following technical solution.
A kind of cable trough seal cover board, 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 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 invention has the beneficial effects as follows:
A kind of cable trough seal cover board of the present invention, 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.

Embodiment
Technical scheme of the present invention 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 seal cover board of the present invention, 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.
