Description
Technical Field
The utility model relates to the technical field of repair protection structures, in particular to a repair protection structure for a concrete road.
Background
The concrete road can appear big pothole after using for a period, pour into pitch in the pothole in order to repair and pack in order to avoid serious, and the shortcoming of waiting to optimize of current technique is public has:
asphalt has poor durability and is easy to crack, fall off, deform and the like.
Disclosure of Invention
The utility model aims at: in order to solve the technical problems, the utility model provides a repairing and protecting structure for a concrete road.
The utility model adopts the following technical scheme for realizing the purposes:
the utility model provides a repair protective structure for concrete road, includes the concrete foundation layer, lays the asphalt pavement layer at concrete foundation layer upper surface, be equipped with reinforced structure in the concrete foundation layer, reinforced structure includes steel reinforcement strip, connecting strip and expansion bolts, the steel reinforcement strip is established in the concrete foundation layer, is fixed with on the pothole expansion bolts, and the welding has between expansion bolts and the steel reinforcement strip the connecting strip.
Structural principle: the expansion bolts are fixed on the pits, the reinforcing ribs are arranged in the concrete base layer, the connecting strips are used for connecting the expansion bolts and the reinforcing ribs, and the concrete base layer and the concrete on the pits are firmly and stably connected through the design reinforcing structure so as to prevent falling and deformation.
The expansion bolts are three in number and distributed on two sides and the bottom of the hollow. The stability of the concrete base layer and the firmness of the connection between the concrete base layer and the concrete are improved by arranging three expansion bolts to form two triangular structures at the bottoms of the reinforcing ribs, and specifically, two adjacent connecting strips, the expansion bolts and the steel frame strips form a triangular structure.
The surface of the steel bar is coated with an anti-corrosion layer. The corrosion protection layer can prevent water, oxygen and other corrosive substances from contacting the surface of the steel bar, thereby prolonging the service life of the steel bar.
And a lime layer, a fine sand layer and a reinforcing layer are sequentially arranged between the asphalt pavement layer and the concrete base layer from bottom to top. The setting of lime layer increases the bearing capacity and the stability on road surface, and the setting of fine sand layer helps the drainage, reduces the influence of moisture to road surface stability.
The reinforcing layer is a nonwoven layer. The arrangement of the nonwoven layer improves the structural stability.
The beneficial effects of the utility model are as follows:
according to the utility model, the connection between the concrete base layer and the concrete is firmer and more stable by designing the reinforcing structure, so that the falling off deformation is prevented; the stability of the concrete base layer and the firmness of the connection of the concrete base layer and the concrete are improved by arranging three expansion bolts to form two triangular structures at the bottoms of the reinforcing ribs; the corrosion-resistant layer can prevent water, oxygen and other corrosive substances from contacting the surface of the steel bar, thereby prolonging the service life of the steel bar.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1
As shown in fig. 1 to 2, this embodiment provides a repair protection structure for a concrete road, which comprises a concrete base layer 1, an asphalt pavement layer 2 laid on the upper surface of the concrete base layer 1, wherein a reinforcement structure is arranged in the concrete base layer 1, the reinforcement structure comprises reinforcing ribs 3, connecting strips 4 and expansion bolts 5, the reinforcing ribs 3 are arranged in the concrete base layer 1, the expansion bolts 5 are fixed on the pits 6, and the connecting strips 4 are welded between the expansion bolts 5 and the reinforcing ribs 3.
Structural principle: the expansion bolts 5 are fixed on the pits 6, the reinforcing ribs 3 are arranged in the concrete base layer 1, the connecting strips 4 are used for connecting the expansion bolts 5 and the reinforcing ribs 3, and the concrete 11 on the concrete base layer 1 and the pits 6 are firmly and stably connected through the design reinforcing structure to prevent falling and deformation.
The expansion bolts 5 are three in number and distributed on both sides and bottom of the hollow 6. By arranging three expansion bolts 5 to form two triangular structures at the bottoms of the reinforcing ribs 3, the stability of the concrete base layer 1 and the connection firmness of the concrete base layer 1 and concrete are improved, and specifically, two adjacent connecting strips 4, the expansion bolts 5 and the steel frame strips form a triangular structure.
