Problems solved by technology

Most of the cable covers currently used are steel bars or other cement covers with internal reinforcement, and the covers are separated from each other and spliced ​​together. The disadvantages of this cable cover are: 1. The weight of the cement cover is too heavy. 2. The cover plates are separated from each other, which is easy to dislocate during long-term use, which is not conducive to the protection of cables in the trench; 3. The cement cover plate is hard and brittle, resistant to pressure difference, and easy to break after long-term use; 4. , Reinforced concrete cover plate cost is high, the situation of theft is serious
An application number is 200620027343.8, and the Chinese invention patent named cable cover has made some improvements to the existing reinforced concrete cover, which has played a certain role, but its disadvantages are: 1. The invention still uses cement-based materials as cable cover material, so the cable cover is heavy in weight, hard and brittle, and the shortcomings such as pressure difference have not been solved; It is suitable for the laying of complex terrain, especially not suitable for the turning and branching of cable trenches
3. The cement-based material cover plate is easily damaged due to bumps during construction, and its service life is short

preparation example Construction

[0066] The preparation method of well cover of the present invention comprises the following steps:

[0067] 1) Add unsaturated polyester resin and low-shrinkage additives into the reactor, close the switch and start stirring at a stirring speed of 600-800 rpm;

[0068] 2), add heavy calcium carbonate to the reactor that has started to stir, then add zinc stearate, continue stirring for 50-80 minutes after adding;

[0069] 3) After stopping stirring, put the raw materials in the reaction kettle into the mixing bucket, add active magnesium oxide, curing agent, carbon black into the mixing bucket, then push the mixing bucket under the secondary mixer, and stir for 10-15 minutes , the stirring speed is 500-700 rpm, so that the raw materials are evenly mixed into a resin paste, and then the resin paste is divided into four upper paste barrels;

[0070] 4) Add non-alkali glass fiber roving to a sheet molding compound molding machine, adjust the gap between the scraper and the tabl...

Abstract

The invention relates to a novel cover plate for a cable trench. The novel cover plate comprises a cover plate body; the front end of the cover plate body has a convex arc shape, while the rear end has a concave arc shape; a hasp which has a convex arc shape is arranged in the middle of the front end; a rear hasp beam which has a concave arc shape is arranged at the rear end; a rear gap which hasa concave arc shape is formed between the rear hasp beam and the cover plate body; and the hasp is matched with the rear hasp beam, and the length of the rear hasp beam is greater than that of the hasp. A side hasp beam which has a concave arc shape is arranged in the middle of two sides of the cover plate body; a side gap which has a concave arc shape is formed between the side hasp beam and thecover plate body; and the length of the side hasp beam is equal to or greater than that of the hasp. Compared with the prior art, the cover plate has the advantages that: the cable cover plates can be randomly connected with each other horizontally or longitudinally; the cover plates are integrated into a whole after completely paved, so the entire compressive strength of the cover plates is improved and the damage of external force to the cable is reduced; and moreover, the pavement requirements on future increase of cable branches and the turning direction of the cable trench can be met.

Description

technical field [0001] The invention relates to a cover plate, in particular to a novel cable trench cover plate. Background technique [0002] The laying of cables is to dig out a ditch for placing cables on the ground, lay the cables in the ditch, cover the ditch with a cable cover plate, and then cover it with soil to ensure the safety of the cables. Most of the cable covers currently used are steel bars or other cement covers with internal reinforcement, and the covers are separated from each other and spliced ​​together. The disadvantages of this cable cover are: 1. The weight of the cement cover is too heavy. 2. The cover plates are separated from each other, which is easy to dislocate during long-term use, which is not conducive to the protection of cables in the trench; 3. The cement cover plate is hard and brittle, resistant to pressure difference, and easy to break after long-term use; 4. , Reinforced concrete cover plate cost is high, the situation of theft is se...
