Abstract
The utility model discloses a waterproof concrete box culvert, it includes box culvert main part (1), box culvert main part (1) constitute by integrated into one piece roof (11) and curb plate (12), and roof (11) and curb plate (12) constitute confined rectangle cavity (13), the junction of roof (11) and curb plate (12) be provided with arc surface (14), and all scribble on the lateral wall of roof (11) and curb plate (12) and be equipped with waterproof coating (2). The beneficial effects of the utility model are that: it has long service life, the mounting cost is low and reliably spend high advantage.
Description
Technical field
This utility model relates to the box culvert that in city integrated piping lane, cable duct, cable tunnel, sewers, aqua storage tank, cross-section underpass, road railway culvert, cable distribution is used, particularly a kind of water-proof concrete box culvert.
Background technology
Nowadays in national basis Facilities Construction, the piping lane i.e. box culvert used by municipal engineering pipeline such as electric power, water supply and drainage, combustion gas, electric power is flourish.But many Urban Underground water levels are shallow, and summer is rainy.Box culvert water proofing property just becomes box culvert gut line the key factor of normal orderly function, as there being the situation of infiltration to occur in box culvert, box culvert itself will be greatly shortened service life, and the maintenance being necessary for carrying out in advance box culvert is installed, and cause civil engineering and pipeline to install the increase of investment.Secondly seeping water in box culvert, the internal multiple pipeline of box culvert will be not normally functioning, and by causing the cutting off the water supply of urban inner region-by-region, suspension, power-off, the situation appearance such as stop the supple of gas or steam, cause the inconvenience that people's day lives.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of service life length, good endurance and the high water-proof concrete box culvert of reliability.
The purpose of this utility model is achieved through the following technical solutions: a kind of water-proof concrete box culvert, it includes box culvert main body, described box culvert main body is made up of integrated top board and side plate, and top board and side plate constitute the rectangular cavities closed, described top board and the junction of side plate are provided with arc surface, and are all coated with waterproof coating on the lateral wall of top board and side plate.
Described waterproof coating is epoxy resin waterproof coating.
The arc radius of described arc surface at least 10cm.
Described box culvert main body is poured by water-proof concrete to be made, and the seepage-resistant grade of box culvert main body is at least P6.
This utility model has the advantage that
1, can ensure that the service life of box culvert, reduce box culvert later stage civil engineering and the input of mounting cost；
2, reduce the probability seeped water by box culvert top board and side plate, it is to avoid the corrosion of box culvert main body reinforcement in concrete, thus improve the durability of box culvert, make the reliability of box culvert be protected.
3, the various pipelines run in avoiding box culvert are not normally functioning because of box culvert infiltration.

In figure, 1-box culvert main body, 2-waterproof coating, 11-top board, 12-side plate, 13-rectangular cavities, 14-arc surface.
Detailed description of the invention
Being further described this utility model below in conjunction with the accompanying drawings, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, a kind of water-proof concrete box culvert, it includes box culvert main body 1, described box culvert main body 1 is made up of integrated top board 11 and side plate 12, and top board 11 and side plate 12 constitute the rectangular cavities 13 closed, described top board 11 and the junction of side plate 12 are provided with arc surface 14, and on the lateral wall of top board 11 and side plate 12, all it is coated with waterproof coating 2, thus constitute top board 11 and the side plate 12 anti-water surface as box culvert main body 1 outer wall, described box culvert main body 1 is made up of concreting, and the seepage-resistant grade of box culvert main body 1 is at least P6.
In the present embodiment; described waterproof coating 2 is epoxy resin waterproof coating; the waterproof membrane formed after this waterproof coating 2 is cured has certain extensibility, elastoplasticity, crack resistance, impermeability and weatherability; can play and waterproof, anti-blend protective effect; and waterproof coating 2 has good thermal adaptability; easy and simple to handle, it is easy to safeguard.
In the present embodiment; the arc radius at least 10cm of described arc surface 14; top board 11 and box culvert side plate 12 plate section thickness are not less than 250mm; upstream face cover to reinforcement degree is not less than 50mm; in order to ensure box culvert top board 1 and the anti-permeability performance of box culvert side plate 2, the cement consumption of slab culvert concrete is not less than 265kg/m3, water-cement ratio is not more than 0.45.
Operation principle of the present utility model is as follows: the top board 11 that waterproof box culvert is made up of peripheral hardware waterproof coating 2 and water-proof concrete is constituted with side plate 12; water-proof concrete originally has stronger impermeability; in addition waterproof coating 2 is arranged at top board 11 and side plate 12 outer wall; intercept the infiltration of external water source completely; thus play a good waterproof effect, in order to preferably protection box culvert structure and box culvert internal pipeline facility.
