Problems solved by technology

[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. Wall support form, the soil nails of the existing soil 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 soil nails do not cross in the soil, 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.

Abstract

The invention relates to a soil nail grid, which is formed by at least one group of soil nails in the soil. The invention uses grid soil nail and the soil to provide carrying force, to utilize the physical character of soil and soil nail; and it uses the anti-drawing strength of soil nail grid to compensate the defect as low soil anti-drawing strength, with low cost and wide application.

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. Wall support form, the soil nails of the existing soil 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 soil nails do not cross in the soil, the reinforcement effect of the soil nails on the soil is relatively poor. During protection, the suitable de...
