Roadbed construction method for preventing uneven settlement of spliced road

Abstract

The invention discloses a roadbed construction method for preventing uneven settlement of a spliced road, which comprises the steps of roadbed excavation, construction of a drainage system in a roadbed construction period, step treatment, water seepage treatment of an old roadbed, reinforcement construction of a hydraulic dynamic compactor, reinforcement construction of a heavy road roller and settlement deformation observation. A reverse slope is arranged to ensure the compactness of the old roadbed, slope slippage is effectively avoided, and good drainage engineering measures and temporary drainage facilities near a construction site are established in roadbed construction to keep the roadbed in a dry, firm and stable state frequently. A layer of geocell is respectively laid on the bottom surface of the roadbed, the bottom surface of the embankment and the steps in the middle of the roadbed and the embankment, so that the roadbed has higher lateral limitation, skid resistance and deformation resistance, the bearing capacity and the load dispersing effect of the roadbed are effectively enhanced, the junction of the new roadbed and the old roadbed and the new roadbed are reinforced by adopting two modes of dynamic compaction and rolling compaction, and the construction efficiency is improved. And the stability of the roadbed is effectively enhanced.

Description

technical field [0001] The invention relates to the technical field of precision machining methods for semiconductor motion slides of military industry, semiconductors and medical equipment, in particular to a roadbed construction method for preventing uneven subsidence of spliced ​​roads. Background technique [0002] In recent years, with the rapid development of science and technology, aerospace, home appliances, public transportation, biomedical and other fields require high-precision parts with higher precision, lighter weight, and impact resistance.
