Road flatness surveying device for building construction

Abstract

The invention relates to the field of road survey, in particular to a road flatness surveying device for building construction. The road flatness surveying device for building construction comprises afixing support, fixing pipes are fixedly connected to the two sides of the middle of the upper end of the fixing support, fixing frames are fixedly connected to the two fixing pipes through adjustingmechanisms, push plates are fixedly connected to the two sides of each fixing frame, and fixing grooves are formed in the fixing frames. Adjusting mechanisms are installed in the lower portions of the fixing grooves, and the fixing support is connected with an installation frame in a clamped mode through two clamping mechanisms. A rotating handle drives a rotating rod to rotate, the rotating roddrives a first bevel gear to rotate, the first bevel gear drives a second bevel gear to rotate, and the second bevel gear drives the connecting rod to rotate, so that two third bevel gears drive two fourth bevel gears to rotate, and the two fourth bevel gears drive two first threaded rods to rotate; therefore, two first threaded rods ascend in the two fixing pipes, the heights of the push plates on the two sides of the fixing frame are adjusted, and workers of different heights can push a survey device to move conveniently.

Description

technical field [0001] The invention relates to the field of road survey, in particular to a road smoothness survey device for building construction. Background technique [0002] Engineering survey, on-the-spot survey and mapping work to find out the geological and geographical environment characteristics in the construction area and other natural conditions related to engineering construction, flatness detection is sometimes called frontal degree detection and coplanarity detection. In the process of highway and building construction, ensuring the flatness of construction is an important technical quality assurance. Use flatness testing equipment to collect construction ground data and detect the flatness of the construction bottom surface. [0003] At present, the road surveying devices used are relatively simple in structure, requiring people to hold tools and place them on the ground to observe and measure with the naked eye.

Problems solved by technology

[0003] At present, the road surveying devices used are relatively simple in structure, requiring people to hold tools and place them on the ground to observe and measure with the naked eye. The bending measurement will also lead to an increase in the labor force of the workers, which is not conducive to the health of the workers, and the results of the direct visual measurement of the workers are not accurate enough, and the large value deviation will affect the subsequent road construction, and the tools are not convenient enough to carry and move , the worker needs to hold the tool and pick it up, which makes it very troublesome for the worker to carry and is not conducive to the movement of the tool
