Reconstruction and expansion of expressway slope intelligent protection system

Abstract

The present invention proposes the reconstruction and expansion of the highway slope intelligent protection system, including a power cone penetrometer, a plurality of optical fiber sensors and a mobile engineering vehicle. The power cone penetrometer includes a drop hammer, a penetration rod and a plurality of penetration cones head; the mobile engineering vehicle includes a lifting device, a vertical clamping device and a fixed plate of the vehicle body; the fixed plate of the vehicle body is used to fix the mobile engineering vehicle; the mobile engineering vehicle also includes a data storage module and a data analysis module module; the power cone penetrometer performs penetration sampling on the predetermined target area under the control of the mobile engineering vehicle, and the optical fiber sensor sends the data obtained by each penetration sampling to the data storage module; the data acquired by each penetration sampling includes the penetration depth data of the penetration rod; after the intelligent protection system analyzes the sampling data through the data analysis module, it can be obtained that the expressway is at the Describe the slope expansion scheme of the predetermined target area.

Description

technical field [0001] The invention belongs to the technical field of slope monitoring and protection, and in particular relates to an intelligent protection system for the reconstruction and expansion of expressway slopes. Background technique [0002] Due to the rapid growth of traffic volume in recent years, the four-lane expressway built in the early stage in China can no longer meet the traffic demand, and is facing the task of reconstruction and expansion of expressway. The expansion of the side slopes on both sides of the expressway subgrade also needs to be taken into consideration. The side slope of the subgrade refers to the slope with a certain slope on both sides of the subgrade to ensure the stability of the subgrade. [0003] Excavation of steps is currently a commonly used method for subgrade splicing in expressway expansion projects, and its height and width are determined by factors such as the type of subgrade filling and the bearing capacity of the subgra...

Problems solved by technology

[0007] However, in the existing technology, whether it is the subgrade splicing design and construction in the expressway expansion project, or the selection of the existing expressway slope protection scheme, a large number of engineering and technical personnel are required to manually collect relevant data on site, combined with practical experience. The corresponding reconstruction and expansion or protection schemes have low efficiency and are limited by the experience and subjective knowledge of engineering technicians, and are also limited to the accuracy of on-site data collection. Both efficiency and accuracy need to be improved.
