Method for filling high-filled embankment with rock blocks with superlarge particle size

Abstract

The invention discloses a method for filling a high-filled embankment with rock blocks with superlarge particle size. The method includes the following steps: (1) foundation treatment; (2) laying of the rock blocks with superlarge particle size: the rock blocks with superlarge particle size are separated out; a minimum height of the super-size rocks from the top surface of a foundation is determined; a laying solution for the rock blocks with superlarge particle size is determined, including the determination of the number of laid layers and the determination of the paved length of the foundation; a laying sketch for each layer is determined, and in order to ensure that the embankment containing the rock blocks with superlarge particle size does not ununiformly settle, a method of stagger layering is adopted for laying; laying construction of the rock blocks with superlarge particle size is carried out, and the laying construction is a flow process, which includes three construction links, i.e., loading of the rock blocks with superlarge particle size, unloading of the rock blocks with superlarge particle size and laying of the rock blocks with superlarge particle size; (3) pavement and leveling of the embankment with the rock blocks with superlarge particle size; (4) layer-by-layer compaction of the embankment with the rock blocks with superlarge particle size; (5) dynamic compaction of the embankmen with the rock blocks with superlarge particle size t.

Description

technical field [0001] The invention relates to the technical field of road construction in mountainous areas, in particular to a method for filling high-fill embankments with super-large-sized rocks. Background technique [0002] When the height of the embankment filled with fine materials is more than 6 meters, and the height of the embankment filled with soil or stone in other areas is more than 20 meters, it is called a high-fill embankment. [0003] The high-fill embankment shall be constructed by layered filling and layered compaction, and the thickness of each layer of filling shall be determined according to the filler used. If the sources of fillers are different and their properties are quite different, they should not be filled in sections or vertically. The high-fill embankment located in the submerged road section should use fillers with high water stability and good water permeability, and the slope ratio should not be less than 1:2 to avoid slope instability....

Problems solved by technology

At the same time, a large number of super-large-sized rocks produced by tunneling and excavation are discarded and waste due to their large particle size, which damages the ecological environment.
