Roadbed soil and stone mixed filling equipment and method

Abstract

The invention discloses roadbed soil and stone mixed filling equipment and method. The equipment comprises a feeding conveying device, a stone storage device and a stone laying device which are connected in sequence, and the stone laying device comprises a stone arrangement frame, a plurality of stone falling slideways, an arrangement driving mechanism and a pushing mechanism; a large surface of alarge stone faces downwards and is placed on the feeding conveying device; and the large stones move to the stone arrangement frame from a material conveying and storing device under the action of agravity and are driven by the arrangement driving mechanism to be transversely distributed in a horizontal direction, then the pushing mechanism pushes the plurality of arranged large stones to the stone falling slideways together, the large stones fall onto a base layer along the stone falling slideways together, simultaneous laying of the large stones is achieved, and therefore laying efficiencyis improved. The method comprises the steps that the large stones, small stones and soil materials are sequentially laid, and settlement of the roadbed in the future due to gaps existing in the roadbed is prevented.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of roadbed construction, in particular to a roadbed earth-rock mixed filling equipment and method. Background technique [0002] The subgrade is the foundation of the road surface or track, and it is a geotechnical structure formed after excavation or filling. The main function of the subgrade is to provide necessary conditions for pavement or track laying, driving and trains, and to bear road and traffic loads or static and dynamic loads of tracks and rolling stock, while transferring and diffusing the loads deep into the foundation. [0003] A large amount of soil-rock mixture is produced in the process of road construction in mountainous and hilly areas of our country. The soil-rock mixture is used for laying roadbeds. In addition, it is necessary to place the large side of the large stones downwards to ensure that the gaps between adjacent large stones can be filled with small ...

Problems solved by technology

[0005] To this end, the embodiment of the present invention provides a roadbed earth-rock mixed filling equipment and method to solve the problem of low laying efficiency in the prior art due to the large stones at the bottom layer still being laid manually
