Energy-absorbing, water-guiding and waterlogging-preventing structure for urban road

Abstract

The invention belongs to the technical field of urban highway comprehensive facilities and particularly relates to an urban highway energy-absorbing water-guiding waterlogging-preventing structure. A rainwater well is arranged between the water-permeable asphalt pavement and the water-permeable concrete sidewalk, a well grate is arranged on the rainwater well, a curb is arranged at the end, close to the rainwater well, of the water-permeable concrete sidewalk, and a water-permeable gravel filling layer is arranged below the water-permeable concrete sidewalk and the curb; and meanwhile, a plurality of vertical supporting rib plates are arranged below the pervious concrete pedestrian, a cement mortar leveling layer is arranged below the vertical supporting rib plates and the pervious gravel filling layer, and a pervious sound absorption layer is arranged below the pervious asphalt pavement. The structure can give full play to the combination of energy absorption, water diversion, pier retaining and pavement drainage, rainwater falling on the energy-absorbing road water guide fender pier and rainwater on a permeable asphalt pavement and a permeable concrete pedestrian path can be urgently dredged, and occupation and consumption of excessive manpower and material resources are reduced.

Description

technical field [0001] The invention belongs to the technical field of urban highway comprehensive facilities, in particular to an urban highway energy-absorbing, water-conducting and water-logging prevention structure. Background technique [0002] Most of the isolation piers used at the present stage have poor buffering and energy consumption. When the car loses control and hits it, it can only rely on its own deformation, damage and energy absorption. The deformation ability and energy absorption ability are limited, which often causes car crashes, especially ruptures. The fragments of the fragments hurt people more seriously and cannot effectively prevent the danger from happening. With the massive construction of expressways and urban overpasses and the substantial increase in global car ownership, the incidence of traffic accidents is also showing an upward trend. In addition, both sides of the road isolation pier are often When it rains, it will form ground water or u...

Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the present invention provides an energy-absorbing, water-conducting and water-logging prevention structure for urban roads, which can simultaneously solve the work pressure of sanitation workers to water vegetation, the degree of risk of construction work on roads, and the serious problems of road water accumulation in rainy seasons. 1. The gradual reduction of green plants on urban roads leads to the increase of noise generated by the vehicle body and the increased impact of exhaust gas on the surrounding environment, the frequency of municipal sprinkler vehicles and excessive workload, and the problem of a significant decrease in driving safety due to the weak anti-collision buffer capacity of road abutment piers. The present invention Both sides of the pier adopt multi-through energy-absorbing aluminum plates with a large number of hollow through-holes, and the outer surface is covered with high-density polyurethane foam. After an impact, it is difficult for the multi-through energy-absorbing aluminum plates to break and cause secondary damage to the car body. At the same time, the water-permeable and sound-absorbing layer can absorb a large amount of friction noise generated by the car body running on the permeable asphalt road, reducing the occupation and consumption of excessive manpower and material resources. Compared with the existing technology, the product has prominent substantive features and Significant progress
