Slope protection structure for broken rock cutting side slope

Abstract

The invention discloses a slope protection structure for a broken rock cutting side slope. The slope protection structure comprises an overall hole window type slope protection wall located on a slope. Hole windows are transversely and longitudinally formed in the hole window type slope protection wall at intervals. The slope protection structure is characterized in that longitudinal strip-shapedditches are longitudinally downwards indented in the slope and transversely arranged at intervals, a plurality of longitudinal strip-shaped bases are arranged on the bottom face of the hole window type slope protection wall, and each longitudinal strip-shaped base is correspondingly embedded in the corresponding longitudinal strip-shaped ditch. By organically combining the longitudinal strip-shaped bases and the hole window type slope protection wall, in the presence of the longitudinal strip-shaped bases, the meshing force of the protection slope and the slope is greatly improved; by formingan organic whole with the hole window type slope protection wall and the broken rock cutting side slope, the defect that an existing hole window type slope protection wall is prone to creeping along aslope and is prone to emptying and cracking damage is overcome.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering slope reinforcement, in particular to a slope protection structure for breaking rocky cutting slopes. Background technique [0002] Broken rock cutting slopes are very common in railway and highway engineering in mountainous areas, and the slope surface is often poorly shaped, uneven, and full of broken stones and sediments. In order to meet the anti-scour and stability requirements of the slope, protection is required. The traditional protection types mainly include the following types: (hanging net) shotcrete (or mortar) slope protection, solid slope protection, anchor frame beam combined with plant protection, substrate vegetation , Hole and window slope protection combined with plant protection, etc. [0003] The main disadvantages of traditional protection types are as follows: (1) (hanging net) shotcrete (or mortar) slope protection, solid slope protection slope surface is ...

AI Technical Summary

Problems solved by technology

[0003] The main disadvantages of traditional protection types are as follows: (1) (hanging net) shotcrete (or mortar) slope protection, solid slope protection slope surface is completely closed, without greening, which conflicts with the construction concept of green environmental protection, and has been phased out; ( 2) Anchor frame beams combined with plant protection projects have high cost and large investment; (3) The plant protection effect of the base material is good, and it is suitable for slope protection with high aesthetic effect, but its engineering cost is high; (4) Hole windows The combination of plant protection and plant protection takes into account the aesthetic and economical requirements, but the existing hole-and-window type slope protection only sets the foundation at the foot of the slope, and is directly laid on the slope surface. Due to the sediment on the broken rock slope surface It is difficult to remove during the process. Due to the existence of sediment between the bottom surface of the hole-and-window slope protection and the excavated slope surface, the closeness is poor, and the integrity is not good. After seepage and erosion, there will be a void between the slope protection and the excavation slope, which will lead to cracking, damage and even failure of the hole-and-window slope protection wall.
