Combined rock fall shed tunnel and installation method thereof

Abstract

The invention discloses a combined rock fall shed tunnel and an installation method thereof. The shed tunnel is formed by combining a cast-in-situ pile foundation arranged below a pavement with prefabricated parts, wherein the prefabricated parts comprise a pile foundation arranged below the pavement, a support pillar arranged above the pile foundation, a support beam arranged above the support pillar, and a protection plate arranged above the support beam. The invention has the advantages that: the shed tunnel has a simple structure, low cost, light weight and good protection effect; and more importantly, the parts are made of prefabricated materials, so during use, the shed tunnel can be quickly transported to a construction site by a vehicle or manually, is installed in a combined mode, has high installation speed and can meet the requirement of emergently erecting the shed tunnel to ensure traffic under critical conditions such as continuous mountain landslide and the like caused by earthquake.

Description

technical field [0001] The invention relates to a shed cave, more specifically to a combined rockfall shed cave and an installation method thereof. technical background [0002] my country is a mountainous country, with mountains and hills accounting for more than 2 / 3 of the country's total land area. It is one of the countries with the most severe rock collapse disasters in the world, especially in western regions such as Tibet, Sichuan, Gansu, Xinjiang, Yunnan, and Chongqing. There are hundreds of millions of dangerous rock masses with serious safety hazards along highways, mines and urban areas. In the process of highway construction, it is inevitable to encounter landforms along rivers and mountains. The road construction in the traditional concept is mainly based on excavating road cuttings, but in areas along rivers and mountains, this will inevitably lead to high and large cut slopes. Geological disasters such as dangerous rocks and falling rocks often occur on cutti...

Problems solved by technology

However, the traditional shed hole is constructed of reinforced concrete, which not only has a high cost, but also has a long construction period; after the structure is completed, long-term maintenance is required

[0003] For areas with unstable geological structures, traditional sheds are also vulnerable to damage due to geological changes

Moreover, areas that suffer from severe geological disasters such as earthquakes are often accompanied by continuous aftershocks. Traditional sheds and caves are often not able to be erected in a short period of time, which seriously affects the smooth flow of traffic, which in turn affects the disaster relief and reconstruction of the disaster area. Huge loss of life and property
