Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention is further described: as figure 1 As shown, a reinforcement construction method in the local damage repair of rural cement pavement includes the following steps:

[0026] 1. Excavate the old concrete pavement where the structural damage that needs to be repaired is moderate to severe, and excavate it to the original design elevation of the roadbed. Use a road roller to compact the roadbed until the roadbed no longer settles, and carry out smoothness treatment on the compacted roadbed. Clean the excavated roadbed and old concrete section, and remove the substances that affect the bonding strength between the new concrete and the original roadbed;

[0027] 2. Use a cutting machine to cut the old concrete pavement 1 section along the thickness direction. The cut section and the horizontal plane form an angle of 37°. Remove impurities that affect the overlapping parts of the cement concrete to be poured ...

Abstract

The invention provides a reinforcing construction method in partial failure repairing of a rural cement pavement. The reinforcing construction method comprises the following steps: excavating an old concrete pavement needing to be repaired to the top surface of a roadbed and cleaning; cutting the excavated old concrete pavement and thus cutting the pavement into an inclined plane along the thickness direction of the road surface; respectively paving one layer of steel wire net on each of the bottom and the middle pat of the inclined section; paving thread steel bars and extending to a road surface region needing to be newly poured; pouring concrete into an excavated region of the old road surface to form a new concrete road surface. The invention aims to solve the road surface crushing problem in old cement road surface diseases of rural highways and useful resources including steel wires, steel bars and the like which are usual in villages can be effectively utilized; the engineering cost is saved and a repairing technology is simple, so as to provide a simple, economical and effective method for repairing the road surfaces of rural roads.

Description

technical field [0001] The invention relates to a method for repairing partial damage of concrete pavement, in particular to a reinforcement construction method for repairing local damage of cement pavement in rural areas. Background technique [0002] In the development of highway construction in my country, cement concrete pavement widely exists due to its characteristics of strong base and thin surface, aging resistance, low pollution, high strength, high hardness, and low cost, especially in rural roads and village roads. Cement is basically used pavement. However, with the rapid development of the rural economy and the increase in traffic volume and vehicle load, the damage to the old cement concrete pavement has become more and more serious. Potholes, roadbed subsidence, poor drainage, large-scale fragmentation, and local collapse have occurred in many road sections, making repair work more and more important, although there are many repair methods for old cement concr...
