Description

Large-diameter steel corrugated pipe culvert construction positioning system Technical Field The invention belongs to the technical field of steel corrugated pipe culvert construction, and particularly relates to a large-diameter steel corrugated pipe culvert construction positioning system. Background The steel corrugated pipe culvert is a circular or arched tubular structure formed by rolling and splicing corrugated metal plates, is widely applied to culverts, channels and drainage engineering in infrastructure such as highways, railways, water conservancy and the like, and has the advantages of light dead weight, strong deformation resistance, quick construction, strong adaptability to foundations and the like due to the fact that the large-diameter (generally more than 1 meter in diameter) steel corrugated pipe culvert is particularly suitable for high-filling road sections and soft soil foundations. In the prior art, the on-site butt joint installation of the large-diameter steel corrugated pipe culvert generally depends on that after a pipe joint to be installed is lifted to the vicinity of the end part of the installed pipe joint by large-scale lifting equipment, the repeated lifting and rotation actions of the lifting equipment are completely performed, and in combination with manual use of tools such as a crowbar, a jack and the like, trial fine adjustment is performed so as to align bolt holes of flange plates at the end parts of the two pipe ends. The method has the obvious defects that firstly, the gesture fine adjustment response of the heavy pipe joint in the high air is slow, the operation process is seriously dependent on the cooperation of the experience of a crane driver and a ground worker and Gao Pinci, the efficiency is low, the parallelism and the center height difference of the flange plate are difficult to precisely control, the quality hidden trouble of abnormal installation stress of a connecting bolt or poor interface sealing is easily caused, secondly, the whole leveling and aligning process is long in time, the large-scale hoisting equipment is occupied for a long time to carry out fine operation, the construction economy is poor, and more importantly, a worker carries out high-strength prying correction under the suspended weight, meanwhile, the crane needs to carry out millimeter-level fine motion with higher risk, and the safety risk of man-machine cooperation operation is obvious.
