Mountain Causes and Prevention of the damaged roads

Drainage facilities to ensure smooth road drainage, structural stability and driving safety. Vertical drainage: Ditch the change of soil or concrete mortar rubble ditch, embankment to prevent the infiltration of surface water; subgrade drainage within: additional blind ditch, sewer, water from the body in a timely manner; subgrade drain off water: water erosion in the roadbed and bridge of the lot increase the number of diversion dike (dam), pick the dam, masonry and foot care, to divert water flow and reduce erosion. 2.3 to restore and protect the ecological environment along the highway planting trees and grass along the road, not only beautify the environment, and strengthening the stability of the embankment slope, water erosion reduced the establishment of shelter-based, supplemented by soil and water conservation projects of ecological protection system; for tall slope, should be combined with the local natural and climatic conditions, plant some roots developed, fast growing trees, and planting grass,[link widoczny dla zalogowanych], increasing vegetation, enhance water and soil conservation, strengthening soil, reduce surface runoff erosion on the slope. 3 damaged mountain road mountain road repair and management of water damage, all sorts of wonders. The restoration project, and some can be simple and direct repair, some are not a simple fix that can solve the problem as is, but according to the actual situation of the place unreasonable amendment to the original structure, targeted to be radical in order to receive the expected results . 3.1 Governance of the damaged road surface elevation of the lower sections of road, water, roads have been damaged, should be raised roadbed; Mud gravel road, low-lying areas may be paved with cement concrete or stone pavement, reduce water erosion. 3.2 roadbed subsidence and the collapse of the embankment settlement governance governance: weak foundation reinforcement, can be used for indigenous, mixed with lime, lime pile method, etc., increasing subgrade strength, to prevent embankment subsidence; Yanhe Road embankment,[link widoczny dla zalogowanych], flood roads and other long-term flooding embankment, setting the embankment, slope protection and other protective measures; sections of high water table, laying sand substrate (gravel) cushion, block capillary water rise; mortar flagstone in the gutter and road pavement structure with dense to prevent rainwater infiltration Foundation ; subgrade springs within the set up blind ditch or sewer, water discharge in a timely manner. Embankment collapse of governance: masonry retaining wall treatment. Masonry retaining wall is a mountain highway embankment collapsed governance the main method, based on actual terrain, the use of different forms of retaining wall: slope is not high, Shouli Bu large, no water can be used directly to the erosion of puzzle pieces of dry stone retaining wall Otherwise, masonry retaining walls to be some need to pouring concrete retaining special section. Puzzle slope, around bamboo cages processing. Susceptible to water erosion of the slope, slope protection should be paved to prevent erosion. The basis of poor and vulnerable to water shocks Linhe subgrade, can be bamboo cages (built-in stone) envelope, such as WINNER beam line at the 5K, Linhe filling subgrade, water year was empty and the cost of large masonry retaining wall, with a diameter 80CM,[link widoczny dla zalogowanych], length 2M in bamboo cages, containing pebbles, close toe stand in rows,[link widoczny dla zalogowanych], filling the inside of compaction, the effect of economic and practical play. Let stone arch, ceiling beam treatment. Collapse inside corner, the higher the slope, the radius of a small section, or lots of rock, stone arch can be resolved. Such as governance and the 17K at the County Government nine lines, steep slopes, other methods are difficult to solve, choose the location for bagging two protruding points, the use of stone arch supporting the road, play the desired results. Rock slope section of reinforced concrete slab can also be used outside the pick processing, such as the Canada Line Shaowu 8K Department, the collapse of one third of the roadbed, retaining the embankment and the slope are rock,[link widoczny dla zalogowanych], set to take the side of reinforced concrete beams into the slope (not less than 50CM), while challenges to the roadbed outside the edges of 2M intervals along the beam reinforced concrete slab poured for the road, play the desired effect. 3.3 The bridge destroyed by the destruction of part of the governance of the bridge repair, but also according to the construction of weirs and other water conditions modulating structures, regulate water flow, ensuring the bridge design will not be destroyed when the flood level. Destroyed parts of the bridge by appropriate reinforcement, such as the bridge empty and application of concrete filling deposits in the society section, then place reinforced concrete reinforced foundation. Mountain road culvert should be a reasonable layout, the diameter culvert (culvert) or wall not less than the height 100CM, sand and debris to facilitate discharge, and artificial dredge cleaning. Culvert construction, the foundation should be prepared to deal with to ensure a solid base culvert; water IZl should be paved mortar rubble, and the establishment of shade well; water IZl big gap, but also laying down water structures or equipment to reduce water erosion. 4 Conclusion damaged mountain road control, to rely on science and technology, combined with characteristics of mountain road, constantly applying new technologies, new knowledge in engineering practice; Although the damaged roads caused by a variety of reasons, but as long as we can learn from design, construction and road preventive maintenance and other side attaches great importance to take effective control measures to prevent the main, combining prevention with control, damaged roads will be effectively controlled.
