Method for highway or railway to pass through large and medium congelifraction clastic flow areas

Abstract

The invention discloses a method for a highway or a railway to pass through large and medium congelifraction clastic flow areas, and relates to a method for a highway or a railway to pass through special geological disasters. The method comprises the steps that the positions of a traffic project planned route in the clastic flow areas are determined; a first row of concrete column foundation is arranged on the upper portion of the slope of the traffic project planned route, and the depth of the lower end, entering a stabilizing bed rock, of each protecting net pile foundation is no less than 10 m; a protecting net is installed at the upper end of the first row of concrete column foundation, and each protecting net pile foundation obliquely pulls and fixes a corresponding gravel retaining pile through a plurality of anchor cables; and bridge abutments are arranged on the two sides of each clastic flow area correspondingly, two rows of reinforced concrete column foundations are arranged in the clastic flow areas, bridge plates are erected on the bridge abutments and the two rows of reinforced concrete column foundations, and highway facilities or railway facilities are laid on the bridge plates. By means of the method, the highway or the railway can be laid in the clastic flow areas, and geological disasters of congelifraction clastic flows to highway or railway traffic projects are effectively avoided.

Description

technical field [0001] The invention relates to a method for roads or railways to pass through special geological disaster bodies, in particular to a method for roads or railways to pass through large and medium-sized frozen weathered debris flow areas. Background technique [0002] In my country's Tibet, Xinjiang Tianshan and other alpine mountainous areas, there is a special geological disaster body - frozen weathered debris flow. The geological disaster body is in a loose structure, mainly composed of gravel and a small amount of debris. With the advancement of the western development, the above-mentioned alpine mountainous areas ushered in the spring of social and economic development, and many projects are in the preliminary planning and design work, including some major national and local engineering projects, such as Yunnan-Tibet railway, power transmission and transformation For engineering projects such as large reservoirs and hydropower stations, except for railway...

AI Technical Summary

Problems solved by technology

[0004] At present, there are no precedents of road or railway engineering on the accumulation of frozen weathered debris flow at home and abroad. How to arrange road or railway engineering on the accumulation of frozen weathered debris flow safely, effectively, economically and reasonably is an important topic worthy of research
