With the rapid development of economy in China, the living standard of people is continuously improved, and the number of vehicles is increased day by day, so that the construction scale of roads and bridges is continuously enlarged. In the construction of road engineering, the thickness of each structural layer of a road surface directly determines the stress characteristic of the road and the durability of the road surface, and the accurate measurement and lofting of the elevation of each structural layer of the road surface is an important link in the construction process of the road surface. In road pavement construction, the cushion layer, the base layer and the bottom middle surface layer are basically constructed by adopting a wiring method to confirm the elevation, the construction process mainly comprises the steps of embedding deformed steel bar → measuring and marking the high layer → hanging line, and the accuracy of the measurement on the deformed steel bar directly determines the accuracy of the thickness of each structural layer of the pavement, so that how to quickly and accurately determine the hanging line high layer is particularly important for correctly guiding the construction.
From the view of the road surface layer constructed by the traditional wire hanging method in China, the method for confirming the high layer on the deformed steel bar mainly comprises the following two types, wherein the first type is a two-step measuring method, namely, the high layer at the bottom or the top of the deformed steel bar is measured firstly, and the wire hanging position is measured by a measuring tape according to calculation; the second type is suspended measurement, namely, the sliding staff is moved up and down to the high-rise hanging line by manpower on the premise of ensuring the verticality of the sliding staff. Above-mentioned two kinds of methods, there is great measuring error all, to this, the utility model designs this kind of accurately measure high-rise device of hanging wire in road surface work progress.
The method comprises the following two steps: when the method is adopted, because two times of measurement are involved, not only is the accumulated error increased, but also the consumed time is longer, and meanwhile, when the threaded steel is not embedded with enough verticality, the measuring error of the tape measure is particularly large.
Suspension measurement: when the method is used for measurement, the limitation of manpower is caused, the verticality of the sliding staff cannot be guaranteed, and after a high-rise building is measured, the marked position cannot be guaranteed to be a measurement position when marking is carried out due to shaking of hands.
