Old cement pavement disease treatment construction process and drilling device

Technical Field

Background

With the acceleration of road construction, concrete pavement has many advantages that make it widely used in road construction. As the traffic increases, some plastic deformation of the underfloor base occurs. After the load is driven off, the plastic deformation of the part cannot be completely recovered, and the local supporting condition is weakened or void is formed. When the cement concrete pavement slab has the void condition, a gap is formed between the pavement slab body and the base layer, and the slab corners or edges of the pavement slab are easy to be bent under the action of load, at the moment, the working state of the pavement slab is similar to that of a cantilever beam, and under the action of load, the slab corners or edges generate excessive stress and bending. Under the repeated load, the transverse fatigue cracking of the pavement slab is very easy to cause. Many diseases such as cracks, broken plates and the like of cement concrete pavement during use are almost all related to the void of the plate bottom; and some of the slabs, even though they appear to be neither broken nor cracked, may still have void at their bottoms. The disease caused by the void road surface is hidden, but the damage is very large, and potential safety hazards exist for pedestrians and vehicles on the road.

The current method for treating the cement pavement slab void comprises the following steps: expanding the crack, supplementing repairing materials such as cement concrete and the like into the crack, and flattening the surface. But the repairing effect is not very good, the repairing material can not completely flow to the void of the pavement slab body and the base layer to form stable connection, and the condition that the slab body of many pavements is again void or the slab body is broken within 2 and 3 years after repairing seriously affects the pavement performance of the pavement, and the service life of the cement concrete pavement is prolonged, so that huge economic loss is caused.
