In the following embodiments, the demolition project does not involve aerial work and deep foundation pit construction, the demolition difficulty is low, the risk is small, but the requirement on safe and civilized construction is high. The breaking method comprises the following steps:
the reinforced concrete pavement or the asphalt pavement is dismantled by cutting a slot with a cutting machine, crushing with a hydraulic crusher, cutting the reinforcing steel bar with oxyacetylene and cleaning, wherein the hydraulic crusher travels backwards, and the large-area concrete pavement is dismantled in blocks according to the field condition so as to ensure the construction progress.
And (3) breaking the road surface, determining the designed elevation, positioning the middle pile, and calculating the dismantling height difference between the existing elevation and the designed elevation by a measurer. And marking the pile numbers according to the calculated height difference. According to the field condition, organizing construction, firstly using a pneumatic drill fleet to carry out point-to-point punching and seam forming on the old pavement to crack the old pavement. Organizing an excavator, and carrying out centralized clearing on the broken road surface lumpy waste residues by a loading vehicle, and transporting to a specified waste soil site.
For narrow road sections and the road surface is a double-layer concrete road surface, a large cutting machine is adopted for cutting the road surface, the cutting depth reaches 0.4m, the large cutting machine is used for transversely cutting after longitudinal cutting, and the road surface is cut into bean curd blocks to be crushed.
