Problems solved by technology
[0004] The purpose of the present invention is to provide a road marking and positioning device that is convenient for night construction, so as to solve the problem that the existing night marking proposed in the background technology requires the erection of lighting facilities, which is relatively cumbersome, and because the lighting of lighting facilities The angles are different, and there is a phenomenon of crossing shadows. It should be the problem of the construction personnel's positioning and marking of the road.

The invention discloses a road marking and positioning device convenient for night construction, and belongs to the technical field of road construction. The device comprises a positioning box body Iand a positioning box body II, the positioning box body II is arranged on the right side of the positioning box body I; a fixing ring is welded on the outer wall of the positioning box body I; a take-up and pay-off roller is fixed on the outer wall of the positioning box body II through a bolt. According to the invention, an infrared emitter and an infrared receiver cooperate with each other; thepositioning box body I and the positioning box body II can be in an aligned state so that a positioning marked line is in a straight line state; the phenomenon of positioning deflection is avoided; meanwhile, fluorescent hanging plates which are uniformly hung above the positioning marked lines have a fluorescent light-emitting function; by means of the fluorescent hanging plate, lineation personnel can conveniently conduct lineation positioning work according to the position of the fluorescent hanging plate, lighting facilities do not need to be erected again, the lineation construction complexity is reduced, and meanwhile the situation that the lineation personnel conduct lineation positioning work due to shadows is avoided.
Description
technical field [0001] The invention relates to the technical field of road construction, in particular to a road marking and positioning device convenient for night construction. Background technique [0002] According to the scope of service and its status and role in the national road network, it is divided into: national roads (national roads), including expressways and main trunk lines; provincial roads (regional roads); county and township roads (local roads) ;city road. The first three are collectively referred to as highways, which can be divided into five technical grades according to the annual average day and night vehicle traffic volume, usage tasks, and nature. Different grades of roads are represented by different technical indicators. These indicators mainly include calculation of vehicle speed, number and width of lanes, subgrade width, minimum flat curve radius, maximum longitudinal slope, sight distance, road surface grade, bridge and culvert design load,...
