This invention discloses a method for transporting tall, long arch ribs on complex mountain roads. The core process includes road surveying and transportation simulation, a proportional arch rib transportation passability test, precise loading and locking of the arch ribs and installation of attitude monitoring devices, transportation along a preset trajectory and point-of-care inspection, and three-level graded acceptance and control. This invention employs a self-righting, low-center-of-gravity counterweight vertical transport scheme, equipped with prefabricated tooling that can adapt to longitudinal slopes and small-radius turns, and features a gravity balance sensor to automatically adjust the arch rib attitude. A dedicated braking system is customized for the transport vehicle. This invention effectively lowers the transportation center of gravity and road traffic requirements, reduces road widening projects, saves costs, protects the environment, solves the problem of transporting tall, long arch ribs on complex mountain roads with steep longitudinal slopes and small-radius turns, improves transportation safety, avoids arch rib deformation and damage, and ensures construction quality.

This invention discloses a roadbed survey unit, detection system, and analysis method for addressing road hazards. The unit includes a survey box with a settlement detection mechanism inside for detecting roadbed settlement depth. A horizontal adjustment unit is located diagonally at the bottom of the survey box. The settlement detection mechanism includes a detection plate, the top of which is driven downwards by a pneumatic component. This invention relates to the field of road surveying technology. This roadbed survey unit, detection system, and analysis method for addressing road hazards, by incorporating a settlement detection mechanism, utilizes a pneumatic component to move the detection plate vertically downwards. The moving plate moves synchronously through the pulling of a traction rope and the cooperation of a support component. This not only enables subsequent roadbed settlement detection but also improves the accuracy and efficiency of the detection process by cleaning the test surface with a sweeping plate before settlement detection.

This invention relates to the field of image data processing technology, specifically to a digital highway surveying method and system based on machine vision. The method includes: acquiring multimodal data collected by a vehicle-mounted mobile scanning system; obtaining a hazard type matching deviation value under the current sampling based on the multimodal data; obtaining the feature vector of the multimodal data in the neural network under the current sampling, and determining the identifiable impact performance value under the current sampling based on the hazard type matching deviation value; obtaining random coefficients under the current sampling based on the identifiable impact performance value; determining the hazard type saliency under the current sampling based on the identifiable impact performance value and the random coefficients; dynamically adjusting the attention weights of the neural network using the hazard type saliency under the current sampling, and outputting the highway hazard identification result. This invention can improve the accuracy of edge feature extraction for multiple types of highway hazards.

The utility model provides a kind of measuring device for highway reconnaissance design belongs to road surveying equipment technical field.The utility model embodiment provides the measuring device for highway reconnaissance design, including staff component, drill, direct current motor, power component and support and adjusting mechanism, by rotating and setting drill in the end of staff component, direct current motor and the power component of power supply to direct current motor are built-in in the inside of staff component, when needing to insert staff component into the soil of ground survey point, only need to insert drill into the soil of ground survey point, then start direct current motor, make drill automatic drilling into the soil of ground survey point by direct current motor drive drill rotation, simultaneously, drill drives staff component to insert into the preset position in ground soil, so as not to need to insert staff component into the ground survey point by measurement personnel manually, save work time and improve measurement efficiency, can greatly reduce the labor intensity of measurement personnel, not easy to cause measurement personnel to appear fatigue.
