Abstract
The invention discloses a cable working well cover plate, which comprises a bearing layer and an anti-slip layer which is fixedly connected to the surface of the bearing layer, wherein the bearing layer and the anti-slip layer are in an anti-arch bridge shape; the bearing layer is shaped and formed by coating a steel reinforcement framework by employing bulk molding compounds; the anti-slip layer is shaped and formed by the bulk molding compounds; and transverse and vertical anti-slip stripes in a staggered mode are formed on the surface of the anti-slip layer. The cable working well cover plate has the characteristics of low recycling value, high bearing capacity, high durability, moderate weight and anti-slip effectiveness, and a vehicle does not generate noise while driving through the cover plate.
Description
Technical field
The present invention relates to a kind of cable work manhole cover plate.
Background technology
Power cable line is transmission and distribute one of critical element of electric energy in the electrical network.Worker's well is the abbreviation of active well, and it is the underground structure for trailing cable and field joint.The position of worker's well generally at the nonmotorized vehicle lane of urban road, also is located at sidewalk or motorway.Aboveground of cable work is exactly cover plate, and cover plate not only can play the effect of protection cable run, and when cable run need to overhaul, the maintainer can directly open cover plate, and the trouble point segmentation is accurately located.Simultaneously, because the cable work well will be arranged on the road that people's car may pass through sometimes, a solid reliable cover plate can effectively guarantee the safety of passing people's car.
At present, the cable work manhole cover plate that use various places mostly is pouring concrete and forms, and adopts the protection of 10# channel-section steel cornerite all around.Therefore, there are following problems:
1) load capacity is poor, because cement cover board self load is poor, can only be applicable to generally speaking on greenbelt or the sidewalk, rolls and very likely causes the covering plate structure cracking when it is subject to automobile.The cover plate of steel concrete system is rolled by gravity for a long time can produce " digging husky " phenomenon, and after a period of time, concrete desertifies and runs off, and reinforcing bar is partly exposed, and out well lid is uneven, and pedestrian's trip and vehicle pass-through have been caused serious potential safety hazard.
2) steal seriously, because housing has angle steel, inside is bar construction, and the thief often patronizes, and makes the cable work well become genuine " trap ", and passing pedestrian and vehicle have been caused potential safety hazard.
3) noise is serious, because the cover plate manufacture craft is coarse, causes the cover plate excesssive gap, can produce noise when motor vehicle, bicycle and pedestrian's process cable shaft, affects peripheral resident.
4) easily get rusty, perishable because the concrete cable work manhole cover plate processed outsourcing material that uses now is angle steel, its surface only is painting protection, gets rusty easily and is corroded.
5) preponderance, the weight that the cable work manhole cover plate of reinforced concrete system is every generally need 2 to 3 people just can move more than 50 kilograms at least, have greatly tied down the efficient of making an inspection tour and rushing to repair.
Summary of the invention
The object of the invention is to overcome the defective of prior art and provide a kind of recycle be worth little, weight capacity strong, good endurance, vehicle do not cross and can make a noise, weight appropriateness and effective anti-skidding novel cable worker manhole cover plate.
The technical scheme that realizes above-mentioned purpose is:
A kind of cable work manhole cover plate comprises bearing course and the skid resistant course that is fixed in this bearing course surface, wherein:
It is anti-arch-shaped that described bearing course and skid resistant course all are;
Described bearing course adopts Bulk Molding Compound (bulk molding compound, BMC) parcel cage of reinforcement to mould moulding;
Described skid resistant course adopts Bulk Molding Compound to mould moulding, and this skid resistant course surface is furnished with the anyhow anti-skidding striped of alternative form.
Above-mentioned cable work manhole cover plate, wherein, the thickness of described bearing course is 75～85mm.
The invention has the beneficial effects as follows: the present invention adopts Bulk Molding Compound, so cost is moderate, long service life, withstand voltage, corrosion-resistant and almost do not have a recovery value; The present invention further improved the weight capacity of cover plate, and because cage of reinforcement is wrapped up by Bulk Molding Compound, vehicle does not cross and can make a noise by the design of anti-arch-shaped design and Bulk Molding Compound parcel cage of reinforcement.Simultaneously, the anti-skidding striped of the anyhow alternative form of layout can be effectively anti-skidding.Therefore weight appropriateness of the present invention does not exist the problem of tying down the efficient of making an inspection tour and rushing to repair.
Description of drawings
Fig. 1 is the structural representation of cable work manhole cover plate of the present invention;
Fig. 2 is the structure phantom drawing of bearing course among the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, cable work manhole cover plate of the present invention comprises that bearing course 1 and affixed (as bonding) are at the skid resistant course 2 on this bearing course 1 surface, wherein:
Bearing course 1 and skid resistant course 2 all are anti-arch-shaped, thereby have better weight capacity, and anti-arch-shaped concrete size is decided on actual conditions; In the present embodiment, the long 150mm of the present invention, wide 50mm, described anti-arch-shaped be circular arc (as shown in Figure 1), the central angle of this circular arc is 40 degree, and the radius of circle that justify at its place is 220mm;
Skid resistant course 2 adopts Bulk Molding Compound to mould moulding, and the surface uniform of skid resistant course 2 be furnished with the anyhow anti-skidding striped 21 of alternative form, compare other types, the anti-skidding striped 21 of anyhow alternative form as shown in Figure 1 more can effectively prevent from skidding;
Bearing course 1 adopts Bulk Molding Compound parcel cage of reinforcement 11 to mould moulding, and the thickness of bearing course 1 is 75～85mm, the weight capacity of Effective Raise cover plate, and so that vehicle does not cross can make a noise.In the present embodiment, bearing course 1 is 80mm; Cage of reinforcement 11 is to consist of along the curved surface of bearing course 1 and with the cross one another reinforcing bar of specific interval, as shown in Figure 2.
In sum, the present invention have recycle to be worth that little (anti-theft), weight capacity are strong, good endurance, vehicle cross and can not make a noise and effective anti-skidding characteristics, because there is not the problem of tying down the efficient of making an inspection tour and rushing to repair in the weight appropriateness, has very high practical value simultaneously.
Above embodiment is only for explanation the present invention's, but not limitation of the present invention, person skilled in the relevant technique, in the situation that do not break away from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
