Technical Field

The invention relates to the technical field of road maintenance, in particular to a pavement repairing method.

Background

after the highway construction is accomplished and is put into use, through a period of wearing and tearing, road surface damage, hollow phenomenon can appear, need intercept the road when maintaining at present, use the machineshop car to chisel the damaged road surface, fill pitch after clearing up again, it is well known, the cost of machineshop car is very high, this to the routine maintenance of road, undoubtedly greatly increased the maintenance cost, and the required equipment of this kind of repair mode is numerous, area is big, operator's the amount of labour is big, the work period is long, the normal use of road has been influenced. In addition, in the traditional road maintenance, after a damaged road surface is chiseled, concrete is usually filled for treatment, and then asphalt is filled, so that the combination effect of the concrete and the original roadbed is not ideal, and the filled road surface is often damaged again after being used for a long time; the tamping method is also adopted for improving the strength of the filled concrete, but when the filled concrete is tamped, the original roadbed can be damaged, and the service life of the adjacent pavement is influenced.

Therefore, based on the above-mentioned drawbacks, there is still a need for research and improvement of new road surface repairing methods in the field of road maintenance, which is also a research focus and focus in the field of road maintenance at present, and is the starting point and the driving force of the present invention.

Disclosure of Invention

In view of the above-mentioned drawbacks, the present inventors have made extensive and intensive studies and, as a result, have completed the present invention after having paid full inventive efforts.

Specifically, the technical problems to be solved by the present invention are: the pavement repairing method is convenient to operate, can quickly repair damaged pavements, does not affect the service life of adjacent pavements, and shortens the pavement maintenance period.

In order to solve the technical problem, the technical scheme of the invention is to provide a pavement repairing method, which comprises the following steps: measuring the area of the damaged road surface, and drawing a closed ring around the damaged road surface according to the shape of the damaged road surface, wherein the closed ring surrounds the damaged road surface; (2) excavating the damaged base in the closed ring, wherein the distance between the edge of the excavated damaged base and the closed ring is 20-30 mm, and the excavation depth is up to the foundation of the damaged base; (3) manufacturing a steel ring matched with the shape of the closed ring, wherein the height of the steel ring is equivalent to the excavation depth, the steel ring is sunk to the foundation of the damaged base along the closed ring, and the upper top surface of the steel ring is 5-10 mm lower than the road surface; (4) cleaning damaged groups in the steel ring; (5) filling concrete in the steel ring and tamping; (6) laying a reinforcing steel mesh above the concrete in the steel ring; (7) welding and fixing the periphery of the reinforcing steel net and the inner wall of the steel ring; (8) pouring asphalt; and (9) compacting.

In the method for repairing a road surface according to the present invention, as a preferable embodiment, the lower end of the steel ring is provided with a blade edge.

In the road surface repairing method of the present invention, as a preferable mode, the sharp corner of the blade leg is inclined from the outer surface of the steel ring to the inner surface of the steel ring.

In the method for repairing a road surface according to the present invention, as a preferable mode, an annular flange is provided on an inner surface of the steel ring, and the annular flange is located at an upper end of the steel ring.

In the method of repairing a road surface according to the present invention, as a preferable mode, an edge of the concrete abuts against a lower surface of the annular flange.

In the pavement patching method of the invention, as a preferable technical scheme, transverse steel bars are arranged in the concrete.

In the method for repairing a road surface according to the present invention, preferably, the ends of the transverse reinforcing bars are abutted against the inner surface of the steel ring.

in the road surface repairing method of the present invention, as a preferable embodiment, in the step (6), the upper surface of the reinforcing steel net is 5 to 10 mm away from the upper top surface of the steel ring.

In the pavement repair method, as a preferable technical scheme, the concrete comprises the following materials in parts by weight: 20-35 parts of cement, 20-30 parts of sand, 28-45 parts of stones, 14-16 parts of water, 4-6 parts of calcium sulfate whiskers and 7-9 parts of organic silicon resin.

In the pavement patching method of the invention, as a further preferable technical scheme, the concrete comprises the following materials in parts by weight: 20-35 parts of cement, 20-30 parts of sand, 28-45 parts of stones, 14-16 parts of water, 4-6 parts of calcium sulfate whiskers, 7-9 parts of organic silicon resin and 0.5-1 part of sodium percarbonate.

By adopting the technical scheme, the invention has the beneficial effects that:

(1) The invention uses the steel ring to isolate the damaged base from the complete road surface, and only constructs in the steel ring, not only the construction period is short, the repaired road surface after construction has high strength and long service life, but also the service life of the adjacent road surface is not affected during construction.

(2) Because the lower extreme of steel ring is equipped with the sword foot, can make the steel ring sink fast to under the sword foot effect, can concentrate the steel ring intra-annular with the damaged base of reserving in the closed ring, make the steel ring on the one hand sink the route perpendicular to road surface, do not harm peripheral road bed, on the other hand is convenient for clear away the intra-annular damaged base of steel.

(3) Because the edge top of concrete leans on the lower surface of annular flange, is equipped with horizontal reinforcing bar in the concrete, and horizontal reinforcing bar has increased the intensity after the concrete shaping for the wholeness is stronger after the concrete shaping, and the annular flange of steel ring receives the supporting role at the edge of concrete, and the bearing capacity of steel ring also improves by a wide margin, can not sink along with ground pressure's increase and sink, has prolonged the life on repair back road surface greatly.
