Problems solved by technology
[0004] So far, domestic and foreign road traffic repairs on mud-rock flow silted sections are still in the passive defense stage, that is, after each mud-rock flow breaks out, excavators, loaders, and manual methods are used to dredge. The heavy workload and long traffic interruption time cannot meet the needs of emergency disaster reduction

Embodiment
[0039] A kind of preferred scheme that the present invention selects, as attached Figure 6 Shown, the diameter of the upper bottom of the round table is d, the diameter of the lower bottom is D, the length of the side edge (i.e. the bus bar) is R, d gets 20cm, D gets 80cm, and R gets 100cm; then the upper bottom surface perimeter of the bearing umbrella 11 is S 1 = πd, the perimeter of the bottom surface is S 2 = πD.
[0040] see Figure 9 , when the size of the circular platform is determined, the allowable bearing capacity of a single bearing umbrella 11 can be obtained by calculation, take σ s is the allowable bearing strength of the bearing umbrella 11 (kpa), σ r is the allowable bearing capacity of debris flow deposits (kpa). Regardless of the back pressure effect of the debris fluid around the bearing umbrella 11 on the outer wall of the umbrella, if it is used as a safety reserve for improving the bearing capacity of the bearing umbrella 11, then there is

The invention discloses a method for realizing the emergent passing of the traffic on a mud-rock flow-silting road section by adopting a load bearing umbrella, wherein the load bearing umbrella comprises a plurality of metal rods, high-strength waterproof cloth, an anchoring bolt and a vent valve, wherein a circular table with a closed upper bottom face and an opened lower bottom face is formed by enclosing high-strength waterproof cloth; the metal rods are arranged in the direction of the bus of the circular table and are uniformly distributed on the side face of the circular table, and the length of the metal rods is same as that of the bus of the circular table; the anchoring both is arranged in the center of the bottom face on the circular table, and the vent valve is arranged at the position adjacent to the anchoring bolt on the bottom face on the circular table; and the load bearing umbrella can be folded. The invention also discloses a method for realizing the emergent passing of the traffic on the mud-rock flow-silting road section by adopting the load bearing umbrella. The method is suitable for the emergent repairing of the road traffic of the mud-rock flow-silting road section, can effectively shorten the breaking time of the road traffic of the mud-rock flow-silting road section, and can recover the traffic passing within 2 to 3 days after mud-rock flows stop moving.
Description
technical field [0001] The invention relates to a rapid restoration technology for road traffic after a mud-rock flow, in particular to a method for realizing traffic emergency passage by using a bearing umbrella and the bearing umbrella. Background technique [0002] my country is a mountainous country, with mountains and hills accounting for more than 2 / 3 of the total land area. It is one of the countries with the most developed debris flows in the world, especially in western regions such as Tibet, Sichuan, Gansu, Xinjiang, Yunnan, and Chongqing. More than 6,000 large-scale and super-large debris flows have been identified, and tens of thousands of potential debris flow ditches have occurred. Frequent occurrence of debris flow disasters has caused strong impact and silt damage to road traffic, resulting in traffic interruption. With the vigorous development of western my country, the construction of transportation infrastructure has been developed rapidly, but the serious ...
