Abstract

The invention discloses a flexible reinforcement combination protection structure for controlling humidification and damage for a soft rock strong weathering zone. In the invention, in a residual soil layer (1) arranged at the upper part of a side slope, an excavated surface is laid with a first layer of geotextile (7) and spread plant loam (6), and is planted with grass; a soft rock of a strong weathering rock zone (2) arranged at the middle part of the side slope is reinforced by a flexible reinforcement retaining structure; and a weak weathering soft rock (3) arranged at the lower part of the side slope is protected by three-dimensional planting grass (5). The flexible reinforcement retaining combination protection structure is capable of stabilizing the side slope and greatly reducing the work amount, is simple and convenient in technology, rapid in construction speed, economical and environment-friendly, and can be used for resisting humidification and damage for the soft rock side slope strong weathering zone.

Description

technical field

[0001] The invention relates to a retaining and protective structure for road cutting slopes, in particular to a flexible reinforced composite protective structure for preventing and controlling wet damage in soft rock strong weathering zone. Background technique

[0002] Red-bed soft rocks are often prone to form a residual soil and strongly weathered rock zone with a thickness of 6m-10m in the suitable weathering position. When the soft rock strong-weathered rock zone contains local water retention, the red-bed soft rock in the strong Wet, once excavated, the strong weathered rock zone is often used as the shear outlet, causing shallow collapse and damage. Sometimes, this type of collapse and damage is also caused by the wetting of the soft rock and strong weathered rock belt after the construction is infiltrated by rainfall. At present, in order to prevent the damage of this type of excavation slope, the anchor frame beam is often used to reinforce the sl...
