A construction method for a rockfall retaining structure on a slope dangerous rock

Abstract

The invention relates to the technical field of geotechnical engineering, and discloses a construction method for a rockfall retaining structure on a slope, which adopts a double-layer cement blanket, a profiled steel support and an anchor rod to form a retaining wall structure for reinforcing piles and piles, replacing traditional steel bars. The concrete retaining wall structure uses a single-layer cement blanket, a horizontal fixed frame and a vertical fixed frame to form the concrete construction formwork of the retaining plate, and the concrete construction formwork of the corresponding part of the reinforcement pile on the ground, replacing the traditional construction formwork. The construction method proposed by the invention has the advantages of simple operation, high construction efficiency, environmental protection and low safety risk, greatly reduces the number of construction personnel entering and leaving the site, reduces the demand for concrete and the curing time of concrete pouring, and controls the construction cost of the blocking structure. Conducive to popularization and application, especially suitable for high and cold plateau slope environment.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a construction method of a rockfall retaining structure for a slope dangerous rockfall. Background technique [0002] Dangerous rocks and rockfalls are widely distributed on the high and steep slopes in mountainous areas, especially in the southwestern mountainous areas of my country, where there are a large number of dangerous rockfalls and high and steep slopes. When the road construction passes through difficult and dangerous mountainous areas, the reinforcement and protection of dangerous rocks and rockfalls becomes the key to the safe operation of the road. The key is that the construction of pile-plate retaining wall is a common construction method in the protection of dangerous rockfall. [0003] The air oxygen content in the plateau area is low, the labor efficiency of personnel is low, and the construction safety risk is high. The construction and mainten...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method of pile-slab type retaining wall construction method in the prior art, which has insufficient practicability and is very difficult to construct in the environment of high plateau, high cold and high steep slopes, and to provide a method for rockfall on dangerous rocks on slopes. A construction method for a retaining structure, which is convenient for construction, high in construction efficiency, low in safety risks, and conducive to popularization and application. The retaining structure formed by this method is easy to maintain and has good economic efficiency, and is especially suitable for dangerous slopes in plateau, high, cold, high and steep areas.
