The application provides a manhole anti-falling net installation construction management system and method, and relates to the technical field of municipal pipe network construction management.The application realizes real-time monitoring of a manhole construction object, collects facility number, spatial coordinates, pre-construction, in-construction and post-construction images and timestamp information, constructs a unique identifier of the construction object and generates a standardized information body;on this basis, the spatial consistency coefficient of the construction object, the construction process integrity coefficient and the construction result reliability coefficient are calculated respectively, and compared with the corresponding threshold value for evaluation;when the evaluation result is unqualified, the control strategies such as automatic repositioning, supplementary shooting and recording, rework or manual review are triggered, the abnormal data flow is suspended, and the update and recording are completed until the evaluation meets the standard.The method realizes spatial verification, process constraint and result quality control of the manhole anti-falling net construction process, and improves the construction authenticity, data reliability and management efficiency.

This utility model relates to a microscopic observation device for soil particles in shaking table tests, belonging to the technical field of civil engineering experimental equipment. It includes a vibrating base that supports the entire device and provides controlled vibration power; a fully transparent model box is mounted on the vibrating base to hold the soil particle sample to be observed, and the bottom layer of the fully transparent model box has symmetrically arranged wave-absorbing sponge layers on its left and right sides; a miniature camera assembly is mounted on the vibrating base, vibrating synchronously with the fully transparent model box; the miniature camera assembly includes a camera with high-speed continuous shooting capability, and the frame rate of the miniature camera assembly is not less than 300fps; a horizontal electric guide rail is mounted on the vibrating base; and a vertical electric lifting column is mounted on the horizontal electric guide rail. This utility model effectively eliminates the relative displacement problem caused by the asynchronous movement of the camera equipment and the model box in shaking table tests.
