Slope surveying and mapping positioning calibration device and use method thereof

Abstract

The invention relates to a side slope surveying and mapping positioning and calibrating device and a use method thereof, and discloses a positioning and calibrating device for positioning an excavation line by using an RTK measuring instrument to position an excavation point and then pulling a scattering barrel to move along a guide groove to scatter white lime powder to the ground along a straight line, and a use method of the positioning and calibrating device. The positioning assembly is arranged on the guiding assembly, the marking assembly is arranged on the guiding assembly, the positioning assembly moves along the guiding assembly to position excavation points, the marking assembly moves along the guiding assembly to connect the excavation points determined by the positioning assembly, and a complete excavation line is positioned.

Description

Technical field [0001] A kind of slope mapping positioning calibration device of the present invention and the method of use thereof relates to a positioning calibration device for mapping the slope and a method of use thereof, which belongs to the field of surveying and mapping engineering technology. Background [0002] In order to prevent the fall of soil and rock masses, on both sides of the road usually need to set up a slope with a certain slope, the current slope excavation usually uses mechanical and manual cooperation to carry out construction operations, specifically, first use excavators and other excavation equipment to excavate the slope to a distance of 20-30cm from the design elevation, and then use manual precision excavation, and finally use manual or rammed earth equipment to flatten and compact the slope, before the slope excavation, it is necessary to use surveying and mapping equipment for construction lofting to obtain excavation lines. The general practice...

Problems solved by technology

[0002] In order to prevent the soil and rock from falling, it is usually necessary to set up slopes with a certain slope on both sides of the driving road. The current slope excavation is usually carried out by means of mechanical and manual cooperation. Specifically, excavators, etc. are used first. The excavation equipment excavates the slope to a distance of 20-30cm from the design elevation, and then uses manual excavation for precise excavation, and finally uses manual or rammed earth equipment to level and tamp the slope. Before excavating the slope, surveying and mapping equipment is required for construction To stake out to obtain the excavation line, the general method is to first use the surveying and mapping equipment to measure the first excavation point, and the surveyors mark and position it, then measure the next excavation point, and then place the two excavation points Connect them together by spraying paint, sprinkling lime, or pulling wires until a complete excavation line is located. However, if the connection method is artificial spraying or sprinkling lime, it is easy to cause bending and deformation of the excavation line, which will affect the excavation of the slope. For the accuracy of excavation, the method of pulling wires can make the excavation line a complete straight line, but it is necessary to bury the setting-out line fixing piles at the excavation point before pulling the wires. The operation is cumbersome, time-consuming and generally cannot be operated by one person.

[0003] Publication No. CN109083152A discloses a construction method for mechanical excavation of slopes, including the steps of: using surveying and mapping equipment to carry out construction lofting to obtain excavation lines; After the instruction, excavate the slope to be excavated to the preset elevation along the excavation line to obtain the rough excavation slope, and use the shovel to trim and compact the rough excavation slope to obtain the standard slope. , first plant control piles on the center line of the well-positioned subgrade, and then excavate along the marked points of the planted control piles. The operation is more cumbersome, takes a long time and generally cannot be operated by one person
