High-roadbed low-riverbed water damage prevention and control structure

Abstract

The invention discloses a high-roadbed low-riverbed water damage prevention and control structure, and relates to the field of highway water damage prevention and control. A foundation toe apron, a step protection slope and a road shoulder wall are connected into an integrated protection structure, and the local foundation structure style is changed, so that the situation that a river does not easily scour the foundation toe of the structure is guaranteed, the roadbed stability is guaranteed, and the instability of a single protection mode under the working condition of a high breakwater and alow riverbed is effectively avoided. Therefore, scouring damage of rivers, floods and the like to a road is effectively controlled from bottom to top, engineering cost and maintenance cost are saved,and repeated water damage is avoided; and compared with other previous single protection structures, the anti-scouring effect is better, the stability and the overturning resistance are higher, engineering is more durable, investment is saved, the drainage function requirements of different scales of fluid (debris flow or flood) of a riverway can be met, the increasingly various transportation safety requirements of oversized heavy vehicles can also be met, and a certain use prospect is achieved.

Description

technical field [0001] The invention relates to the field of highway water damage prevention and control, in particular to a high roadbed and low river bed water damage prevention and control structure. Background technique [0002] Water damage is one of the main disease types of mountainous roads. It is widely distributed and seriously harmful. In addition to directly destroying roadbeds and bridges and culverts, water damage can also induce secondary disasters such as suspended roadbeds, deformation of retaining walls, and cracks in road surfaces, resulting in Road breaks and traffic jams seriously affect and endanger the operation of transportation, and even directly threaten the safety of life and property. In recent years, with the deepening of my country's western development, highway construction will usher in a new round of great development, and highway flood disaster management will become the top priority of highway traffic safety and smoothness, and it is increa...

Problems solved by technology

[0005] How to effectively avoid the local damage and overall instability caused by this form of protection under extreme water erosion, to implement the overall stability of the protection structure and ensure the safety and smoothness of road driving will become the focus of attention this time. The previous roadbed protection structure has shoulder walls , mortar rubble slopes, etc., they often can only deal with flood and debris flow disasters with small water impact and low destructive performance to a certain extent, and cannot play a good role in disaster prevention and control of high subgrade and low water level conditions. Under such working conditions, if the previous subgrade protection method is still used for treatment, it will cause problems such as high engineering cost and repeated repairs. Therefore, we propose a high subgrade and low riverbed water damage prevention structure
