Emergency repair method for road tunnel collapse damage

Abstract

The invention discloses an emergency repair method for road tunnel collapse damage. According to the rapid treatment construction method for the road damage, a corresponding construction scheme is formulated through on-site survey and cause analysis according to a rapid, efficient, scientific and safe emergency principle; stonework and earthwork accumulation bodies are removed through blasting ormachinery; dangerous rock is cleaned mechanically and manually, and roadbed internal supporting is carried out to guarantee passage; emergency rehabilitation of bridges is conducted by erecting temporary steel bridges, floating bridges, culvert bridges or aqueduct bridges and the like; emergency rehabilitation of tunnels is conducted by mechanical excavation of the accumulation bodies and steel support reinforcement and the like; resource allocation is reasonably carried out; necessary safety measures are ensured; and monitoring and early warning in the process are ensured. According to a program starting plan, a task disposal command mechanism is established, the smoothness of command issuing is ensured, delay caused by factors such as fuzzy command functions and information judgment errors is greatly reduced, and the disposal efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of natural disaster accident treatment, in particular to an emergency repair method for road tunnel collapse damage. Background technique [0002] At present, frequent natural disasters have caused different degrees of damage to roads. The existing road emergency emergency treatment technologies are as follows: excavation and filling, excavation and filling leveling: those with less serious disasters can generally pass directly, and serious road sections can adopt the method of repairing damaged parts. Excavate and fill with new materials, or directly fill with earth and stone materials on it to ensure smooth flow. For road sections that have less impact on the stability of the subgrade, mechanical backfilling, leveling, and compaction of subsidence road sections will be used. For large cracks and dislocations in the subgrade, mechanical excavation and filling can be used to level them or the subgrade can b...

Problems solved by technology

[0003] However, after the disaster occurred, the road damage information obtained at the first time was not sufficient, and the judgment of the disaster situation was not accurate enough, such as the type of disaster, the topography of the disaster area, geological conditions, and the scope and degree of road damage, damage type, damage form, and estimated emergency repairs. The amount of engineering, etc., has added a certain degree of difficulty to the formulation of emergency plans
