Method and device for quickly forming ballast collecting platform at high and steep slope
The invention discloses a method and device for quickly forming a ballast collecting platform at a high and steep slope. The method is that an open ground being 4 to 6m in width is prepared below the side slope excavating surface before excavating a side slope; a group of concrete piers is arranged in parallel at the outer side of the open ground, and a steel column is embedded into each concrete pier; net rings are welded on the steel columns; a two-layer ballast stopping nets is pulled and tied to be fixed on the net rings and used as a parapet wall for quickly forming the ballast collecting platform on the open ground. With the adoption of the method in the formation of the ballast collecting platform, a small excavating surface is needed; the high and steep slope can be quickly excavated in an elevation-divided manner; the ballast can be conveniently moved out under the coordination of a dump truck and an excavator; the construction costs a short period; the investment is decreased. Meanwhile, the prefabricated steel columns are embedded into a concrete foundation, so that the formed ballast collecting device can effectively resist the impact force of rolling stones, and as a result, the ballast can be avoided falling into a riverbed directly, and the problem of difficult ballast collection at the high and steep slope can be solved.
