Soil body material reinforced grille

Abstract

The invention relates to a soil body material reinforcing grid in the field of civil engineering. The soil body material reinforcing grid is composed of at least one set of soil nails constructed in an upper body and staggered with each other in a soil body; and provides bearing capacity by the combined action of the grid soil nails and the soil body. The soil body material reinforcing grid gives full play to the mechanical properties of the soil body and the soil nails; overcomes the very low tensile strength shortcoming of the soil body by the high tensile strength of the soil nail grid; has distinct upper body reinforcing effect and low reinforcement cost; and can be used in engineering fields such as slope protection, foundation trench supporting, foundation treatment, etc.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to slope protection, foundation pit support and foundation treatment engineering. Background technique [0002] Existing soil nail slope protection, soil nail wall foundation pit support methods and composite soil nail wall support methods all construct soil nails in the soil, and then connect the soil nails with the reinforced concrete on the slope to form soil nails. In the form of wall support, the nails of the existing nail wall support are generally arranged in parallel or approximately parallel in the soil, although in the patent application of "Soil Nail Support Method for Soft Soil Slope" (application number: CN03112359. 7) The practice of using vertical anchor rods at the excavation surface is disclosed, but because the existing upper nails do not cross in the upper body, the reinforcement effect of the soil nails on the soil is relatively poor. During protection, the suit...

[0002] Existing soil nail slope protection, soil nail wall foundation pit support methods and composite soil nail wall support methods all construct soil nails in the soil, and then connect the soil nails with the reinforced concrete on the slope to form soil nails. In the form of wall support, the nails of the existing nail wall support are generally arranged in parallel or approximately parallel in the soil, although in the patent application of "Soil Nail Support Method for Soft Soil Slope" (application number: CN03112359. 7) The practice of using vertical anchor rods at the excavation surface is disclosed, but because the existing upper nails do not cross in the upper body, the reinforcement effect of the soil nails on the soil is relatively poor. During the protection, the suitable depth of foundation pit support is relatively shallow, which is subject to certain restrictions in engineering applications.
