Description

Technical Field

[0001] This utility model belongs to the field of road engineering technology, and more specifically, it relates to a durable composite drainage pavement structure. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials with mineral materials. Asphalt binder improves the ability of paving aggregates to resist damage to the pavement from traffic and natural factors. However, common asphalt pavement generally has poor drainage. In rainy weather, not only will water accumulate on the road surface, but some of it will also seep into the surface layer of the asphalt pavement. It takes a long time for the accumulated water to evaporate and drain, which not only increases the slipperiness of the road surface, but also easily causes skidding and traffic accidents. Secondly, asphalt pavement is not easy to maintain. After being worn, it needs to be repaired as a whole to keep the road surface smooth. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model relates to a durable composite drainage pavement structure. This structure solves the problems of poor drainage performance of existing common asphalt pavements, where rainwater accumulates on the road surface and some seeps into the asphalt layer during rainy weather. This water takes a long time to evaporate and drain, increasing the road's slipperiness and increasing the risk of traffic accidents. Furthermore, asphalt pavements are difficult to maintain; after wear and tear, they require complete repairs to maintain a smooth surface.

[0004] The first aspect of this disclosure provides a durable composite drainage pavement structure, achieved by the following specific technical means:

[0005] A durable composite drainage pavement structure, comprising:

[0006] The main component includes a lower support layer, which is located at the lowest side; the main component is provided with an external component, the wear-resistant layer of the external component is equidistantly disposed on the upper end of the fixing layer outside the lower support layer, and the limiting block at the outer end of the wear-resistant layer is inserted into the fixing groove in the fixing layer.

[0007] According to some solutions of this utility model, the main component includes: a fixing layer and a fixing groove; the fixing layer is laid on the outer top of the lower support layer; the fixing groove is equidistantly opened at the inner end of the fixing layer.

[0008] According to some solutions of this utility model, the external component includes: a wear-resistant layer and a connecting groove; the wear-resistant layer is a rectangular sheet structure; the connecting groove is disposed around the wear-resistant layer.

[0009] According to some solutions of this utility model, the external component includes: an inner groove and side grooves; the inner groove is opened in the middle position inside the wear-resistant layer; the side grooves are opened on the upper ends of both sides of the inner groove.

[0010] According to some solutions of this utility model, the external component includes: an anti-slip plate and a support block; the anti-slip plate is disposed in the inner groove; the support block is symmetrically disposed on both sides of the anti-slip plate, and the support block is inserted into the side groove.

[0011] According to some solutions of this utility model, the external component includes: a drain hole and a drainage groove; the drain holes are equidistantly opened at the inner end of the wear-resistant layer; the drainage grooves are staggered at the bottom of the wear-resistant layer, and the drainage grooves are connected to the bottom side of the drain hole.

[0012] According to some solutions of this utility model, the external component includes: a limiting block and a connecting plate; the limiting block is located at the bottom four corners of the wear-resistant layer; the connecting plate is located around the bottom of the wear-resistant layer, and the side end of the connecting plate is inserted into the connecting groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this device, an external component is installed. A wear-resistant layer is laid on the upper part of the fixed layer. Circular drainage holes are opened at equal intervals inside the wear-resistant layer, and drainage grooves are staggered at the lower end of the wear-resistant layer, connecting the drainage grooves with the drainage holes. An inner groove is opened inside the wear-resistant layer, and the anti-slip plate is attached to the inner groove through the support block. When it rains, the water will seep through the drainage holes to the lower end of the wear-resistant layer and be guided to both sides of the road through the drainage groove, thereby effectively alleviating the generation of water. By flipping the anti-slip plate so that the side with the curved surface of the anti-slip plate faces upward, the wear-resistant layer can also have an anti-slip function, thereby reducing vehicle skidding caused by wet road surfaces.

[0015] 2. This device includes a main component and an external component. A fixing layer is laid on the upper end of the lower support layer, and a fixing groove is opened in the fixing layer. The wear-resistant layer is laid on the upper end of the fixing layer, and the limiting block at the bottom of the wear-resistant layer is engaged with the fixing groove. Adjacent wear-resistant layers are connected by connecting plates. When a part of the wear-resistant layer is worn and cannot be used, it is only necessary to pry open the local wear-resistant layer for replacement, which can reduce the cost of road maintenance.
