Detailed implementation manners
[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0027] Please refer to Figures 1-5 , the present invention provides a technical solution: a bridge deck paving structure, including a bridge deck 5, a waterproof component 2 is arranged on the top of the bridge deck 5, and a concrete layer 1 is arranged on the top of the waterproof component 2. The concrete layer 1 of the present device is designed with a certain transverse slope during actual construction, generally 1.5% to 2.5%. On a longer bridge surface, a certain longitudinal slope can also be designed, generally less than 0.3%. The material of the concrete layer 1 is high-performance concrete. By setting the concrete layer 1, it has a better waterproof effect and is also more environmentally friendly. The inner sides of the longitudinal drainage ditch 31 and the transverse drainage ditch 46 are both provided with a third waterproof coating 47; the third waterproof coating 47 of this structure can improve the waterproofness of the longitudinal drainage ditch 31 and the transverse drainage ditch 46; a longitudinal drainage component 3 and a transverse drainage component 4 are arranged on the concrete layer 1;
[0028] The waterproof component 2 includes a waterproof isolation component 22, and an upper bonding layer 21 and a lower bonding layer 23 are respectively arranged at the upper and lower ends of the waterproof isolation component 22;
[0029] The waterproof isolation component 22 includes a waterproof coiled material 222, and a first waterproof coating 221 and a second waterproof coating 223 are respectively arranged at the upper and lower ends of the waterproof coiled material 222; a primer 224 is arranged at the bottom of the second waterproof coating 223. The materials of the second waterproof coating 223 and the first waterproof coating 221 are both waterproof coatings; the second waterproof coating 223 and the first waterproof coating 221 of this structure can strengthen the waterproof effect on the bridge deck 5;
[0030] The longitudinal drainage component 3 includes a longitudinal drainage ditch 31. Both ends of the longitudinal drainage ditch 31 have a certain slope to facilitate the drainage into the transverse drainage ditch 46. An interception net 32 is arranged on the top of the longitudinal drainage ditch 31. Through the longitudinal drainage ditch 31, the accumulated water on the concrete layer 1 can be quickly concentrated towards the transverse drainage ditch 46.
[0031] The transverse drainage component 4 includes a transverse drainage ditch 46. One set is arranged at each end of the concrete layer 1 with respect to the transverse drainage ditch 46. A water tank 43 is installed at one end of the transverse drainage ditch 46. One end of a drain pipe 42 is connected to the water tank 43. An interception net 32 is also arranged inside the drain pipe 42 of this structure to intercept impurities such as leaves. A delivery pipe 45 is connected to one side of the water tank 43. A water pump 44 is arranged on the delivery pipe 45. One end of the delivery pipe 45 is connected to a nozzle 48. The nozzle 48 is installed inside the transverse drainage ditch 46. The water tank 43 of this structure can collect the water discharged from the drain pipe 42 for secondary utilization in the cleaning work. Through the water pump 44, the water can be sprayed out from the nozzle 48 towards the collection tank 41 end, facilitating the impurities to enter the inside of the collection tank 41. A drain pipe 42 is arranged at the bottom of the transverse drainage ditch 46. A collection tank 41 is arranged on one side of the transverse drainage ditch 46. The water inside the collection tank 41 can be directly discharged. One side of the collection tank 41 is open, and the opening corresponds to the position on one side of the transverse drainage ditch 46. The left and right sides of the transverse drainage ditch 46 of this structure are provided with a certain slope towards the drain pipe 42 to facilitate quick drainage. A limiting block 410 is fixedly connected to the inner wall of the opening of the collection tank 41. A baffle 49 is rotatably connected to the inner side of the opening of the collection tank 41. The baffle 49 is located on the left side of the limiting block 410. The collection tank 41 of this structure can centrally collect impurities such as leaves, thereby realizing automatic cleaning and avoiding blockage of the drain pipe 42. By setting the baffle 49, it can be rotated to the left to allow the impurities and water to enter smoothly, while the limiting block 410 can limit the baffle 49, and the baffle 49 cannot be opened to the right to prevent the impurities collected inside the collection tank 41 from running out again.
[0032] Working principle: When using this bridge deck paving structure, first, the accumulated water on the top of the concrete layer 1 enters the inside of the transverse drainage ditch 46 through the longitudinal drainage ditch 31, and then is filtered and discharged into the inside of the water tank 43 from the drain pipe 42. When a certain amount of impurities accumulate at the drain pipe 42, it can be automatically cleaned. The water pump 44 is started. The water inside the water tank 43 is sprayed out from the nozzle 48 through the delivery pipe 45 and sprayed inside the transverse drainage ditch 46, and the impurities at the bottom of the transverse drainage ditch 46 are pushed towards the collection tank 41 end, causing the impurities and water to push the baffle 49 to rotate and open and enter the inside of the collection tank 41. When the cleaning work is completed, the baffle 49 automatically resets under the influence of gravity and is limited by the limiting block 410, so that the baffle 49 plays a role in intercepting impurities.
[0033] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
