Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] refer to figure 1 , figure 2 and image 3 , a rapid-construction lightweight anti-seismic subgrade structure of the present invention includes a reinforced concrete base 20 , a reinforced concrete rib column 10 and a prefabricated reinforced concrete panel 40 . Reinforced concrete bases 20 are arranged at intervals along the longitudinal direction of the subgrade in the foundation pit S on the outer side of the subgrade. The lower ends of the reinforced concrete rib columns 10 are consolidated with the reinforced concrete bases 20, and fixedly arranged on each reinforced concrete base 20 are connected with the reinforced concrete rib columns 10. Steel plate limit pier 30. A fixed reinforced concrete prefabricated panel 40 is installed between two adjacent reinforced concrete rib columns 10, and a shock-absorbing buffer filter layer 50 is arra...

The invention discloses a lightweight earthquake resistance roadbed structure rapid in construction and a construction method of the lightweight earthquake resistance roadbed structure, to greatly improve the through capacity and the construction speed of railway roadbeds in dangerous mountain areas, effectively reduce the occurrence rates of bridges and tunnels and also reduce the construction cost of traditional large retaining structures. The lightweight earthquake resistance roadbed structure comprises steel reinforced concrete bases, steel reinforced concrete rib columns and steel reinforced concrete prefabricated plates, wherein the steel reinforced concrete bases are arranged in foundation pits outside the roadbed at intervals and distributed in the longitudinal direction of the roadbed; the lower ends of the steel reinforced concrete rib columns are fixedly connected with the steel reinforced concrete bases; steel plate limit piers connected with the steel reinforced concrete rib columns are fixedly arranged on the steel reinforced concrete bases. One steel reinforced concrete prefabricated plate is fixedly mounted between the two adjacent steel reinforced concrete rib columns, a damping buffer layer is arranged on the back side of the steel reinforced concrete prefabricated plate, and foamed lightweight soil is poured on the back side of the damping buffer layer for forming the roadbed on the slop of the mountain.
Description
technical field [0001] The present invention relates to civil engineering, in particular to a fast-constructed lightweight anti-seismic subgrade structure and its construction method, especially suitable for steep-slope subgrade projects of railways and highways in high-intensity earthquake areas, and can also be applied to subgrades in areas where landslides and debris flows occur frequently The project was quickly repaired. technical background [0002] Construction of railways in difficult and dangerous mountainous areas, the terrain is steep, and the cantilever of the subgrade support structure is high. Under the action of earthquake load, the economy is poor, and the subgrade filling and construction of the support structure in the steep slope area are difficult, resulting in many similar sections being passed by bridges. , so that the railway-bridge-tunnel ratio in mountainous areas remains high. The invention proposes a low-cost, quick-constructed, safe and reliable ...
