Abstract

The invention discloses a construction method and a system of a roadbed brush slope. The construction method of the roadbed brush slope comprises the following steps of digitally modeling, obtaining spatial positions of tips, comparing the positions, and constructing the brush slope; the construction system of the roadbed brush slope comprises an excavator body, an inclined sensor, a GPS (Global Positioning System) receiving device and a data processor, wherein the inclined sensor, the GPS receiving device and the data processor are installed on the excavator body, the inclined sensor and theGPS receiving device are respectively connected with the data processor, and the data processor is connected with the power output end of the excavator body. According to the construction method and the construction system, an excavator bucket is controlled to move to the reference position of the roadbed brush slope according to the difference between the spatial positions of the tips and the reference position of the roadbed brush slope so as to construct the brush slope, heavy measuring and lofting work and a large amount of labor input in a traditional brush slope method are saved, additionally, the utilization rate of machinery is greatly increased, the construction efficiency is improved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the field of roadbed construction, in particular to a roadbed slope brushing construction method and system. Background technique [0002] Excavator construction is often used for traditional subgrade brush slope, and manual measurement and setting-out auxiliary means are used to control the formation of subgrade brush slope. Although it has been practiced for many years, it still needs to be improved in terms of roadbed forming accuracy, machine utilization, construction cost and efficiency. Especially with the large-scale construction of proving grounds in my country, the inclination angle of some curved high-speed ring roads in some proving grounds is too large, which is a super-large slope road type, which makes such problems more prominent. For example, the high-speed ring road built by Shanghai Volkswagen Automobile Co., Ltd. The road is a 21% transverse single-sided slope curve section with a radius of 1500m. If the trad...
