Problems solved by technology

[0007] (3) Due to the poor integrity of loose soil landslides and broken rock and soil slopes, they are easy to deform, and it is difficult to transmit the sliding force to the stable surrounding rock body through the anchor cable
[0008] The above three deficiencies are the fundamental reasons for the poor treatment effect of loose rock and soil slopes and landslide anchoring projects at home and abroad, and there are still serious safety hazards in the treatment projects!

Embodiment Construction

[0027] The present invention can effectively solve the problem of loose rock and soil slope and landslide control. The "nail-anchor composite anti-sliding control structure" consists of reinforced concrete latticework, anchor rods or anchors on lattice beams, and anchors at corner points of latticework. The cable consists of three parts. The technical idea is that the anchors or anchors on the lattice beam can improve the overall rigidity of the loose rock and soil mass of the slope and the landslide mass engineering treatment area, making it a quasi-rigid body and strengthening the rock and soil mass of the lattice foundation. The prestressed anchor cable can anchor the rock-soil mass (quasi-rigid body) with high rigidity in the treatment part in the stable rock-soil mass (surrounding rock), and bear the thrust and earth pressure of the bulk slope and landslide. To achieve anti-skid support effect.

Abstract

The present invention discloses a nail-anchor combined anti-slide treatment method and its treatment structure. Said method includes the following steps: (1), leveling and ramming ground base; (2), setting reinforced concrete lattice, it is made up by combining lattice beams; (3), arranging anchor rods or anchor nails on the lattice beams; (4), setting anchor cable in every lattice corner point position respectively; and (5), applying prestressing force to every anchor cable.

Description

technical field [0001] The invention relates to a technology for treating side slopes and landslides, in particular to a nail-anchor composite anti-skid treatment method and its treatment structure. Background technique [0002] my country is a mountainous country, and the area of ​​mountains and hills accounts for about 70% of the total land area. Taking the western region as an example, in the past 10 years, the rapid development of high-grade highways, mountainous towns, water conservancy and hydropower and other civil and water conservancy projects has produced more and more artificial slopes, such as those along the highways in Chongqing with a height of more than 30m. The cumulative length of high-cut slopes can exceed 300km, and these artificial slopes and a large number of landslides have serious safety hazards (see Figure 1 ~ Figure 4 ). Effective control of these slopes and landslides to avoid geological disasters is of great significance for embodying people-ori...
