The novel base layer paving elevation control device comprises a steel chisel, an adjusting assembly is arranged on the outer surface of the steel chisel, and a stabilizing assembly is arranged at the bottom end of the steel chisel; the adjusting assembly comprises a sleeve in sliding connection with the outer surface of the steel chisel, the outer surface of the sleeve is fixedly connected with a first nut, the inner side of the first nut is in threaded connection with a first bolt, and the end, away from the first nut, of the outer surface of the sleeve is fixedly connected with a horizontal rod; the end, away from the sleeve, of the horizontal rod is fixedly connected with a second nut, the inner side of the second nut is in threaded connection with a second bolt, and the top end of the second bolt is rotationally connected with a top plate. According to the novel base layer paving elevation control device, the adjusting assembly is arranged on the outer surface of the steel chisel, the adjusting assembly can conduct coarse leveling and fine leveling, the adjusting precision is improved, meanwhile, adjustment can be conducted in the paving process of the paver, operation is easy, precision is high, and use is convenient.
Description
technical field [0001] The invention relates to the technical field of highway construction, in particular to a novel base-level paving elevation control device. Background technique [0002] Highway construction refers to the general term for highway network planning, highway survey and design, highway construction, maintenance, management, etc. The scale of highway construction in a country is based on the role of highway transportation in the comprehensive transportation system, and its The importance of the aspect is determined in combination with the geographical environment conditions. [0003] The road base and surface mainly bear the action of the transmitted vertical force of the wheels, and spread it into the cushion and soil foundation. The top surface elevation reflects the flatness index, which affects the driving comfort (reflected to the surface layer). ) and the consumption of surface layer materials, the elevation control device is required when paving the ...
