Abstract

The invention belongs to the field of bridge construction, and particularly relates to a roadbed crushing device for road and bridge construction. The device comprises a crushing box, wherein a main crushing chamber and two auxiliary crushing chambers are arranged in the crushing box, two main crushing rollers are rotatably connected into the main crushing chamber, two auxiliary crushing rollers are rotatably connected into each auxiliary crushing chamber, and a screen is fixedly connected into the main crushing chamber and located under the main crushing rollers. Stone can be crushed for thefirst time through the arranged main crushing chamber, the crushed stone can be screened through the arranged screen, unqualified stone is removed, in addition, the unqualified stone can be crushed for the second time through the arranged auxiliary crushing chambers, and therefore the whole device can screen and treat the crushed stone for the second time; and the trouble of later manual screeningand reprocessing is avoided, the manpower is greatly saved, and the working efficiency is improved.

Description

technical field

[0001] The invention belongs to the field of bridge construction, in particular to a road bed crushing device for road bridge construction. Background technique

[0002] Bridge construction is the process of building a bridge according to the design content, mainly referring to bridge construction technology, construction organization, construction management, construction quality, etc. During the bridge construction process, it is necessary to lay a good roadbed, which is the foundation of the track or road surface. Geotechnical structures formed by excavation or filling. The main function of the subgrade is to provide necessary conditions for the laying of tracks or roads and the operation of trains or trains, and to bear the static and dynamic loads of the tracks and rolling stock or the road and traffic loads. The load is transmitted and diffused deep into the foundation, and on the plane, the subgrade and the bridge form a complete line.
