A method for emergency repair of roadbed in mountainous areas

Abstract

The invention discloses a method for urgently repairing a roadbed in a mountainous area. The method includes the following steps that pneumatic picks or mechanical pneumatic picks can be used by hands for drilling and forming holes in a collapse surface, and root piles are distributed; a supporting structure is arranged on the outer edge, and a formwork is erected; foamed light soil is poured in a layering mode; a road surface is laid. The method has the effect of pile foundations taking root anti-skidding piles into account, upper vehicle loads and loads of the foamed light soil itself are transmitted to a lower good rock-soil body, the anti-skidding effect is achieved by backfilling the contact surface position, the light soil is backfilled to play a certain role in skid resistance at the contact surface position of the light soil and the soil body, the features of being light in soil weight and high in intensity of the foamed light soil are simultaneously taken into account, and therefore the function of rapidly urgently repairing the high and steep collapsed roadbed in the mountainous area is excellently achieved. In addition, the method is suitable for rapidly urgently repairing the collapsed roadbed in an ordinary region and for rapidly urgently repairing a narrow working face of the high and steep collapsed roadbed in the mountainous area, and the method for urgently repairing the roadbed in the mountainous area is convenient to operate, rapid, high in reliability, and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of emergency repair of roads, in particular to a method for emergency repair of roadbeds in mountainous areas. Background technique [0002] Mountainous roads are the life passages for mountain people to travel, especially in the southwestern region, which is affected by geological conditions. Mountainous roads have the characteristics of high, steep, and narrow, and in many places this kind of road is the only way to travel. Affected by geological factors, rainfall and other disturbances, the road is often broken, and the southwest side sometimes lasts for several months. At present, the commonly used emergency repair methods include permanent repairs such as gravity retaining walls, pile slab retaining walls, mortar block stones, building bridges, and temporary repairs such as erecting steel bridges and temporary elevated steel structures. These technologies are such as gravity retaining walls, The applic...
