Intelligent system for automatically acquiring instantaneous erosion and deposition topographic data near bridge underwater foundation and surveying and mapping method thereof

Abstract

The invention provides an intelligent system for automatically acquiring instantaneous erosion and deposition topographic data near a bridge underwater foundation and a surveying and mapping method thereof. A supporting platform is fixed to the side wall, located above the free water surface, of the pier. An operation platform is fixed to the outer side of the supporting platform. A transmission device is connected with a surveying and mapping device and then is mounted on a fixed hinge support on the operating platform; a lifting mechanism on the operation platform is connected with the transmission device through a sling and a lantern ring; the terminal computer issues an instruction based on the connection to remotely control the lifting mechanism to adjust the spatial position of the surveying and mapping device and control a stepping motor on the transmission device to drive the long straight steel shaft to rotate; the long straight steel shaft drives the built-in circular pipe torotate through the worm and the concentric turbine; an ultrasonic transducer fixed to the side wall of the built-in circular pipe scans the three-dimensional underwater terrain, then the collected three-dimensional terrain data are wirelessly transmitted to the terminal computer, and then any instantaneous three-dimensional terrain in the scouring and silting development process of the peripheryof the bridge underwater foundation is drawn through a software platform.

Description

technical field [0001] The invention belongs to the technical field of intelligent surveying and mapping of local scouring topography for wading engineering, and in particular relates to an intelligent system for automatically acquiring instantaneous scouring and silting terrain data near the underwater foundation of a bridge. Terrain data is automatically acquired by the surveying and mapping method of the intelligent system. Background technique [0002] With the rapid development of transportation, a large number of wading projects such as bridges across waters have begun to be built, and the number is increasing and the volume is also increasing. The appearance of the bridge disturbs the original normal river flow, which will form a complex three-dimensional vortex system and high-intensity water turbulence, and then form a large three-dimensional local scour pit around the underwater foundation of the bridge. The growth of the three-dimensional spatial scale of local s...
