Problems solved by technology
[0004] The disadvantage of the existing technology is that filling the patching material in the pavement depression is equivalent to increasing the self-weight of the patching material there
However, the design value of the stress strength of the road is determined. When the road surface is subjected to external loads such as pedestrians and vehicles, the subgrade is equivalent to being subjected to the external load and also the self-weight of the repair material, so that the load on the subgrade is increased. Slow sinking, resulting in the phenomenon that the road surface at the repaired position will gradually sink with the roadbed during the process of using the repaired new road

Embodiment 1
[0038] Embodiment 1: a kind of road patching construction technique, as figure 1 shown, including the following steps:
[0039] S1, open the working chamber:
[0040] S1-1, cut the reinforcement groove 3, and cut down the damaged position of the original road 8 to form the reinforcement groove 3 in the shape of a cuboid.
[0041] S1-2, cutting the construction groove 4, cutting the groove bottom of the reinforcement groove 3 downward to form a cuboid construction groove 4, and the construction groove 4 and the reinforcement groove 3 are arranged coaxially. A shelving portion 31 is formed between the notch of the construction groove 4 and the bottom of the reinforcement groove 3 , and the shelving portion 31 is arranged around the circumference of the construction groove 4 .
[0042] S1-3, cutting the buffer groove 5, cutting down the groove bottom of the construction groove 4 to form the buffer groove 5, so that the connection between the construction groove 4 and the buffer g...

The invention discloses a road repair construction process and relates to the technical field of road construction. The construction process comprises the following steps: S1, forming a working chamber, namely cutting a construction groove, cutting the original road damage position to form the construction groove, and forming a supporting table at the groove bottom of the construction groove; S2,mounting a stress structure: mounting a fixing seat, namely mounting the fixing seat on the supporting table; mounting anti-arch steel plates, applying reverse bending moment on two opposite sides ofthe steel plate, enabling the middles of the steel plates to be arched, enabling radian of the arched steel plates to be upward, and mounting the steel plates on the fixing seat to be fixed; S3, casting the surface, namely laying the surface, laying mud above the anti-arch steel plates, and curing until the mud is condensed into the surface layer. The upward pre-stress is provided for the surfacelayer by virtue of the anti-arch steel plates, and the effect of reducing the phenomenon that the pavement is recessed after road repair is achieved.
Description
technical field [0001] The invention relates to the technical field of road construction, more specifically, it relates to a road repairing construction technology. Background technique [0002] Road is the infrastructure for all kinds of trackless vehicles and pedestrians, and it connects the lifeline of the whole city. Under the long-term use of the road, the uneven settlement of the bottom foundation of the road will cause local small area depressions on the road surface. [0003] The Chinese patent with the authorized announcement number CN103086649B and the authorized announcement date on December 03, 2014 discloses a method suitable for rapid repair of road engineering, mainly by filling the repair material into the depression of the damaged road surface, and covering the electric heating device to The repair material is cured by heat to achieve the effect of repairing the depressions on the road surface. [0004] The disadvantage of the prior art is that filling the...
