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. Rockfall to block

Embodiment

[0065] In this embodiment, for a complete optimization method, such as figure 2 As shown, the reinforcement pile 1 is installed on the slope 18, the reinforcement pile 1 and the soil retaining plate 17 cooperate to block the rockfall 19 on the dangerous rock of the slope, the overall height of the reinforcement pile 1 is 4m, and the cross section of the pile well 2 is 2m*2m Rectangular, the depth of pile well 2 is 2m, and shaped steel support member 6 is a square bar member, and the construction method of a kind of side slope dangerous rock falling rock retaining structure of the present invention comprises the following steps:

[0066] A. Reinforcement pile 1 plane positioning, excavation of a section of pile well 2 of reinforcement pile 1; the depth of a section of pile well 2 excavation is 1m, then excavation of a pile well 2 needs to be carried out twice;

[0067] B, laying thickness at the sidewall of pile well 2 is 4cm cement blanket-3, and cement blanket-3 is fixed on ...

Abstract

The invention relates to the technical field of geotechnical engineering, and discloses a construction method of a side slope dangerous rock falling blocking structure, which adopts a double-layer cement blanket, a profile steel supporting piece and an anchor rod to form a retaining wall structure of a reinforcing pile well to replace a traditional reinforced concrete retaining wall structure. A single-layer cement blanket, a transverse fixing frame and a vertical fixing frame are adopted to form a concrete construction formwork of a breast board, and a concrete construction formwork of a corresponding part of a reinforcing pile on the ground is adopted, so that a traditional construction formwork is replaced. The construction method is easy to operate, high in construction efficiency, environmentally friendly and low in safety risk, the number of times that constructors enter and exit the site is greatly reduced, the demanded quantity of concrete and the maintenance time of concrete pouring are reduced, the construction cost of the blocking structure is controlled, application and popularization are facilitated, and the construction method is particularly suitable for the high-cold and high-steep slope environment of the plateau.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a construction method for a slope dangerous rockfall retaining structure. Background technique [0002] A large number of dangerous rockfalls are distributed on the high and steep slopes of mountainous areas, especially in the southwestern mountainous areas of my country. When the road project built passes through difficult and dangerous mountainous areas, the reinforcement and protection of dangerous rockfalls become the key to safe road operation. The key point is that the construction of pile-slab retaining wall is a common construction method in the protection of dangerous rockfall. [0003] The oxygen content in the air in the plateau area is low, the labor efficiency of personnel is low, and the construction safety risk is high. The construction and maintenance of concrete structures in the alpine area are very difficult, and the transportation of materials ...
