Avalanche impact resistant shed with prefabricated retaining wall and assembled arch structure and its construction method

Abstract

The invention provides an anti-avalanche impact shed with a prefabricated retaining wall and an assembled arch structure and a construction method. There are several prefabricated assembled arch structures between the opposite reinforced concrete retaining walls, and energy dissipation buffer layers, several color steel plates are arranged on the several reinforced concrete retaining walls and several prefabricated assembled arch structures, and the energy dissipation buffer layer and some A waterproof layer is laid between the color steel plates; the prefabricated assembled arch structure forms a flexible curved arch ring according to its own weight during the hoisting process; the joints of the reinforced concrete retaining walls, and the joints of the reinforced concrete retaining walls and the roadbed are fixedly connected with grouting sleeves. . The present invention adopts the segmental prefabrication and assembling method to carry out the construction of the shed hole, which is convenient for construction and simple in the operation process, effectively reduces the difficulty of on-site construction, increases the construction efficiency, and more importantly, can resist the huge impact of the avalanche.

Description

Technical field [0001] The present invention belongs to the field of road construction, relates to the construction technology of the shed hole, in particular to the avalanche impact-resistant shed with prefabricated retaining wall and assembled arch structure and the construction method. Background [0002] With the rapid development of China's economic construction, the construction of transportation infrastructure has also extended to the plateau alpine areas, avalanches as a natural phenomenon that often occurs in the cold areas of the plateau, after the disaster snow accumulation pavement, seriously affecting the smoothness of the road, so that the social economy has been greatly affected and lurking a variety of threats. In order to avoid road closures caused by avalanches, sheds are usually set up in avalanche-prone areas to ensure that the roads are smooth. At present, there are two types of sheds: rigid sheds and flexible sheds. Rigid sheds usually have the following def...

AI Technical Summary

Problems solved by technology

Rigid shed holes usually have the following defects: First, cement concrete is used for cast-in-place, which has a long construction period and high cost

Although the flexible shed can use its strong deformation ability to absorb part of the kinetic energy, the instantaneous impact energy of the avalanche is extremely large, and the flexible shed itself has poor snow removal ability, resulting in prolonged impact. huge impact
