Abstract

The invention relates to the technical field of road engineering devices, and particularly discloses a base layer laying device for road engineering. And a lifting base is slidably clamped in a connecting portal frame fixedly connected to one side of the driving platform in the vertical direction. A hopper-shaped stock bin is arranged at the top of the driving platform; the rotating disc is rotationally connected to the bottom face of the lifting base. The bottom face of the rotating disc is vertically and fixedly connected with a scraper in the diameter direction, and rolling cylinders are vertically and rotationally connected to the middles of the front face and the back face of the scraper correspondingly. The bottom end of the rolling cylinder is flush with the bottom end of the scraper. A spiral conveying mechanism with the outer end movably clamped on the top surface of the driving platform is provided with an input port corresponding to the bottom end of the hopper-shaped stock bin. An output port is formed in one end, fixedly sleeved with the lifting base, of the spiral conveying mechanism, a transition groove is formed in the position, corresponding to the output port, of the bottom face of the lifting base, and the elastic telescopic cylinder is connected between the bottom end of the hopper-shaped stock bin and the input port. By means of the device, the problems that in road engineering, the base layer paving efficiency is low, and the base layer material quality is affected during paving are solved.

Description

Technical field

[0001] The present invention relates to the technical field of road engineering apparatus, in particular a base laying device for road engineering. Background technique

[0002] The pavement structure refers to the laying layers constituting the road surface, which mainly has a surface layer, a base layer, and a pad layer according to the layers and effects thereof. The latest "Highway Asphalt Pavement Design Specification" points out that the pavement structure layer consists of three parts: the surface layer, the base layer and the base layer. The previous cushion can be returned to the functional layer or the subgrade. The road is not only affected by the role of the wheel load, but also affected by the natural environmental factors. Due to the effect of driving load and atmospheric factors on the road surface, it is generally gradually weakened with the depth, so the road surface is usually multilayer structure, and the quality of quality materials is laid in ...
