Description

Novel waterproof pavement of bridge pavement

Technical Field

The utility model relates to a pavement field specifically relates to a novel bridge pavement waterproof pavement.

Background

At present, bridge sidewalks in China, such as municipal bridge sidewalks, are paved by waterproof materials, such as homogeneous bricks or slates, so that the paving damage caused by rainwater is prevented.

With the rise of the concept of sponge cities in China in recent years, permeable materials such as steel slag permeable bricks are more and more widely applied to pavement of road sidewalks. In order to meet the integrated paving requirement of the road sidewalk and the bridge sidewalk, the bridge sidewalk is also expected to be paved by using the same material under the condition that the road sidewalk uses permeable materials such as steel slag permeable bricks.

However, the bridge sidewalk adopted in China is paved with a permeable material, so that the permeable material is difficult to be used when the bridge sidewalk is paved, firstly, in rainy days, especially in periods with large rainfall, if the permeable material is adopted, once rainwater permeates into the permeable material and further immerses under a sidewalk slab, the rainwater flows outwards along the cross slope of the slab beam, the outermost side of the bridge is generally blocked by a sidewalk handrail base, the rainwater can be gathered at the outermost side of the concrete pavement of the slab beam, namely under the sidewalk handrail base, and is difficult to be discharged finally, the rainwater is retained on the bridge, the pavement of the bridge, the slab beam, the sidewalk base and the like can be damaged as the retained rainwater amount is increased, steel bars inside the bridge can be corroded in serious cases, and the durability of the bridge is influenced. Second, electric power and telecommunication pipelines are usually arranged and laid under a bridge sidewalk board at present, and the pipelines are sensitive to water and need better moisture-proof and waterproof measures to protect the pipelines, for example, the pipelines are inevitably damaged when contacting with immersed rainwater, and normal production and life are further influenced.

In conclusion, the bridge sidewalk pavement adopted in China at present cannot meet the assumption of paving the permeable material. Therefore, in order to simply and conveniently meet the paving integration requirement of the road sidewalk and the bridge sidewalk, people generally adopt a method of simulating the appearance of the road sidewalk and paving substitutes which are similar to the color and the material of the road sidewalk floor tiles on the bridge sidewalk as the bridge sidewalk floor tiles, such as grey homogeneous bricks, a celadon plate and other waterproof materials. However, these alternatives can only be made to look similar to paving materials for road pavements, such as steel slag permeable bricks. Therefore, the method cannot achieve the effect of simultaneously meeting the requirements of paving integration and waterproofing.

The existing bridge sidewalks have the defects.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

In the present invention, the use of directional terms such as "upper, lower and outer" in the absence of a contrary indication generally means upper, lower and outer as shown in the accompanying drawings.

According to the utility model discloses, a novel bridge pavement waterproof pavement is provided, including pavement slab 1 and the body of mating formation 2, the body of mating formation 2 includes first waterproof layer 21 and permeable bed 22, first waterproof layer 21 sets up on the pavement slab 1, permeable bed 22 sets up on the first waterproof layer 21, pavement slab 1 reaches the edge of the body of mating formation 2 forms pavement cross slope 3 towards ground slope.

Through the above technical scheme of the utility model, when meetting weather such as rainwater, the rainwater falls bridge pavement after, at first contacts permeable bed 22, later rainwater can permeate gradually under the permeable bed 22 but can not permeate in the first waterproof layer 21 permeable bed 22 with gather between the first waterproof layer 21 and form the water film, the water film is finally followed 3 outflow bridge pavement of pavement cross slope, the slope of pavement cross slope 3 can set up according to actual need and requirement, consequently, no longer receives to be restricted in can only adopting waterproof material when mating formation, when bridge pavement realized directly laying real permeable material, can guarantee again that the rainwater in time discharges for bridge pavement not only can not receive the influence of weather such as rainwater, has really realized the integration of mating formation of road pavement and bridge pavement again.

Preferably, the permeable layer 22 comprises permeable bricks, and people can select the permeable bricks with corresponding quantity and quality according to actual needs and requirements when paving, wherein the permeable bricks are of the type of permeable bricks which can be used in the prior art. Preferably, the style of the water permeable brick can be consistent with the brick body of the road sidewalk, for example, the steel slag water permeable brick is generally adopted in the current road sidewalk, and the water permeable brick of the water permeable layer is also the steel slag water permeable brick.

In addition, the thickness of the first waterproof layer 21 may be 5 to 60 mm. Preferably, the thickness of the first waterproof layer 21 is 10 mm to 50 mm. Furthermore, the first waterproof layer 21 may be made of waterproof mortar or waterproof fine aggregate concrete, so that the first waterproof layer 21 has a good waterproof effect. When the thickness of the first waterproof layer 21 is 10 mm to 50 mm, the first waterproof layer can be better fixed with the water permeable bricks, and the strength of the first waterproof layer can be better maintained.

In order to ensure that the first waterproof layer 21 is firmer and has a longer service life, a reinforcing anti-cracking device 4 may be further disposed in the first waterproof layer 21. The reinforcing anti-cracking device 4 can be a device or material with a reinforcing anti-cracking effect in the prior art, preferably, a steel wire mesh or a steel bar mesh can be used. Wherein, the 10-mesh steel wire is preferably adopted when the steel wire mesh is used. Through the setting of reinforcement crack control device 4, can prevent that waterproof mortar or waterproof pea gravel concretes etc. from taking place phenomenon such as flexural brittle fracture and shrinkage cracking when daily use, further guaranteed the life of bridge pavement.

Furthermore, in order to enhance the waterproof effect of the bridge sidewalk, a second waterproof layer 5 may be further disposed between the first waterproof layer 21 and the sidewalk slab 1. Preferably, the second waterproof layer 5 may be made of a device or material having waterproof effect in the prior art, such as waterproof roll or waterproof paint. The bridge sidewalk has double waterproof effects.

In addition, novel bridge pavement waterproof pavement can also include pavement curb 6, pavement curb 6 can set up pavement slab 1 one side, because of the bridge pavement when mating formation, pavement slab 1 with there may be tiny gap of mating formation between the pavement slab 1, pavement slab 1 with there may also be tiny gap between the pavement curb 6, consequently, pavement slab 1 with can fill between the pavement slab 1 and have sealed glue, pavement slab 1 with the gap of pavement curb 6 also can fill there is sealed glue. Through the sealing of the sealant, the function of preventing residual undischarged micro-seepage water from leaking into the sidewalk slab from the gap can be achieved, and the safety of the bridge sidewalk and various pipelines paved under the sidewalk slab is further ensured. In addition to the sealant, an article or method having a sealing function which can be used in the prior art can be used.

Preferably, the sidewalk kerbstone 6 can also be paved with water permeable bricks so as to keep consistent with the common reinforced concrete sidewalk kerbstone in appearance and have water permeability.
