Road system capable of being quickly assembled and constructed

Abstract

The invention discloses a road system capable of being quickly assembled and constructed. The road system comprises a truss structure layer, a grid road surface layer and upright columns. The truss structure layer is supported by a foundation and the upright columns, the grid road surface layer is laid on the upper portion of the truss structure layer and is connected with the truss structure layer by bolts, and truss modules are butted to one another to form the truss structure layer; grid modules are butted to one another to form the grid road surface layer. The road system has the main advantages that the truss structure layer and the grid road surface layer can be modularly produced in factories and can be quickly assembled in construction sites, and accordingly the road construction cycle can be greatly shortened; problems of snow accumulation and water accumulation of existing grid road surface layers and freezing of existing road surfaces can be solved, accordingly, the driving safety can be guaranteed, the gradient of road surfaces can be increased, and bridge construction occupied areas can be saved; the road surfaces can be maintained easily, conveniently and feasibly; the road system is low in construction cost, and as proved by measurement, the construction cost of the road system can be reduced by approximately 1 / 2 as compared with the construction cost of the traditional road structure; the road system is modularly assembled and constructed and further can be modularly detached.

Description

technical field [0001] The invention relates to a road system, which can realize rapid assembly and construction, and is especially suitable for bridge roads. Background technique [0002] At present, the commonly used bridge pavement is a reinforced concrete structure, and the pavement is paved with asphalt or cement. The road system of this traditional structure has the following problems: 1. The construction period is long. The traditional construction method is to build asphalt pavement or cement concrete pavement on the foundation frame of the bridge through the steps of paving, rolling and curing of various layers of building materials. The long construction period not only pollutes the surrounding environment, but also puts great pressure on the already tense urban transportation; 2. The traditional road surface has strict regulations on the slope: the maximum longitudinal slope of the expressway in the frozen and snow-covered area shall not exceed 4% , other roads ...

AI Technical Summary

Problems solved by technology

The road system with this traditional structure has the following problems: 1. The construction period is long

In this way, the construction of the approach bridge requires a large area, and the reconstruction of the old city will greatly increase the cost of demolition and compensation.

At the same time, the distance between intersections in the old city is short, and if the approach bridge is too long, it will miss a certain intersection, causing vehicles to be unable to get on the bridge.

3. Ordinary roads are prone to water, snow or spillage, which poses a safety hazard to vehicles; 4. High construction costs; 5. Road maintenance is time-consuming and labor-intensive, and will also generate dust, construction waste and other pollution

The road closure during the maintenance process aggravated the road congestion and also affected the surrounding commercial areas
