Description
Technical Field
The invention relates to a method for repairing a damaged road of a construction site, and belongs to the technical field of repairing of damaged roads of the construction site.
Background
For roads in construction sites, because heavy-duty vehicles and heavy engineering vehicles for transporting building materials frequently drive through and are generally high in speed, road pavements are damaged quickly. In order not to influence the construction progress, the damaged and heavy road surface needs to be repaired. The traditional repairing method is to dig out the damaged road surface and clean it thoroughly, then repair it according to the standard of building cement road surface, the repairing method is not only slow and seriously affects the construction progress of the construction project, but also for the construction site with narrow construction road, the repairing method can not be realized at all. In order to reduce the damage of the heavy-duty vehicle and the heavy-duty engineering vehicle to the road, it is considered to provide a deceleration strip on the road to slow down the speed of the heavy-duty vehicle. A common deceleration strip for urban roads is also called a deceleration ridge and is a traffic facility which is arranged on a highway and used for decelerating passing vehicles. The shape is generally strip, the cross section is arc or isosceles trapezoid, and the strip is arranged on a road to slightly arch the road surface so as to achieve the aim of reducing the speed of the vehicle; the material is mainly rubber and also metal. The special traffic safety setting is generally arranged on road junctions, industrial and mining enterprises, schools, residential community population and other road sections requiring vehicle slow down and traffic accidents are easy to cause, and is a novel special traffic safety setting for reducing the running speed of motor vehicles and non-motor vehicles. However, the ordinary deceleration strip for the urban road has little effect on heavy-duty vehicles. Therefore, the problem of how to reasonably repair the damaged road concrete on the construction site becomes a problem.
Disclosure of Invention
The invention aims to provide a method for repairing damaged roads in a construction site, which has small influence on the construction progress of construction engineering, can quickly repair damaged roads, can repair narrow construction site roads and has high pavement durability after repair.
The technical scheme provided by the invention is as follows:
a method for repairing a damaged road in a construction site is characterized by comprising the following steps: 1) manufacturing a deceleration strip; the deceleration strip comprises a deceleration strip main body, the deceleration strip main body is a strip-shaped right-angle steel beam, the cross section end of the deceleration strip main body is composed of a long right-angle side and a short right-angle side, a bottom plate is welded at the end part of the long right-angle side, and the surface of the bottom plate is superposed with the plane where the hypotenuse of a right-angled triangle composed of the long right-angle side and the short right-angle side is located;
2) dividing the damaged road section into two parts along the midline of the length direction of the damaged road section to be repaired, repairing one part, and using the other part for continuously passing the vehicle;
3) cleaning a part of the pavement to be repaired, directly repairing the part of the pavement to be repaired on the original pavement, firstly beating a cushion layer by using concrete with common labels, then paving a reinforcing mesh on the cushion layer, and finally paving fine concrete on the reinforcing mesh;
4) respectively arranging deceleration strips in the step 1) at two ends of the repaired road section;
5) pouring concrete in a gap between the speed bump and the end of the repaired road section;
6) and (5) after the concrete of the road section to be repaired is cured to the strength capable of passing through the vehicle, repairing the other part of the damaged road section according to the steps 3), 4) and 5).
The invention has the advantages that: the construction method has the advantages that the damaged road is repaired quickly, the construction progress of the building engineering is influenced little, the narrow construction site road of the available construction road can be repaired, the repaired road surface has high durability, and vehicles are not damaged.

Detailed Description
Referring to the attached figures 1 and 2, the method for repairing the damaged road of the construction site comprises the following steps:
1) manufacturing a deceleration strip; the deceleration strip comprises a deceleration strip body 1, the deceleration strip body is a long-strip-shaped right-angle steel beam, the cross section end of the deceleration strip body is composed of a long right-angle edge and a short right-angle edge, a bottom plate 2 is welded at the end of the long right-angle edge, and the plane of the plate surface of the bottom plate coincides with the plane where the hypotenuse of a right-angled triangle is formed by the long right-angle edge and the short right-angle edge. The deceleration strip can be made of 18 cm channel steel, the length of the channel steel is cut according to the length required by the deceleration strip, a flange plate at one end of the cut channel steel is cut off to form a deceleration strip main body, then the end part of the long edge of the deceleration strip main body is chamfered, the cut flange plate is used as a bottom plate to be welded at the end part of the long edge, and finally bolt holes are punched in the bottom plate at uniform intervals;
2) dividing the damaged road section into two parts along the midline of the length direction of the damaged road section to be repaired, repairing one part, and using the other part for continuously passing the vehicle;
3) cleaning the pavement to be repaired, directly repairing the pavement on the original pavement 3, firstly using concrete with common labels to beat a cushion layer 4 (the cushion layer can also be constructed by fine concrete with the label of C35), wherein the thickness of the cushion layer is 110 mm, then laying a reinforcing steel bar mesh 5 with the reinforcing steel bar interval of 150mm multiplied by 150mm on the cushion layer, and finally laying fine concrete 6 with the thickness of 40 mm and the label of C35 on the reinforcing steel bar mesh;
4) respectively arranging deceleration strips in the step 1) at two ends of the repaired road section;
5) pouring concrete 7 with the reference number C35 in a gap between the speed bump and the repaired road section end;
6) and (5) curing the concrete of the road section to be repaired for more than 24 hours, and repairing the other part of the damaged road section according to the steps 3), 4) and 5) after the concrete reaches the strength capable of passing through the vehicle.
In order to make the repaired road section more durable, roughening treatment can be adopted on the surface of the concrete layer on the uppermost layer, and secondary concrete pouring is carried out when the concrete is damaged again and does not reach civilized construction conditions after being used for a period of time.
The method for repairing the damaged road section has high repairing speed, but the repaired new road surface is higher than the original road surface. If a heavy-duty vehicle running at high speed directly impacts a new road surface, the vehicle is easily damaged, and the new road surface is quickly damaged. However, after the deceleration strips in step 1) are respectively arranged at the two ends of the repaired road section, when a heavy-load vehicle comes, the vehicle is decelerated when meeting the deceleration strips, and then the vehicle smoothly runs on the newly repaired road surface under the guidance of the inclined surface of the deceleration strips, so that the vehicle is not damaged, and the new road surface is well protected due to the fact that the running speed of the vehicle is reduced.
Example (b):
the project of reforming the grain-carrying riverside shed house area in the city of the week opening is characterized in that the whole underground garage is adopted, the usable construction road is narrow, the construction road can only be arranged along the loop line of the deep foundation pit, and under the repeated rolling of a heavy engineering vehicle, the influence of the precipitation of the deep foundation pit on the road foundation is added, the road concrete is seriously damaged, and how to reasonably restore the construction is difficult. The method is successfully applied to the project engineering of improving the grain-carrying riverside shed house area in the Zhou city, and achieves a very good effect.
