Abstract

The invention discloses a large unconsolidated soil and stone body slope protection structure and method. Flexible rubble net cage masonries are fixed around rigid anti-slide piles, and a rubble filter layer is arranged on one side. Water in slopes can be rapidly and effectively discharged through the rubble net cage masonries and the rubble filter layer, and therefore landslides are avoided. A rigid and flexible combined protection system is formed by the rigid anti-slide piles and the flexible rubble net cage masonries together, the deformation range of the flexible masonries is large, and therefore sufficient early warning time can be provided. Water accumulated at the deep bottoms of the slopes can be rapidly discharged through filtering and guiding water tanks and anti-slide wall toes of a base, and meanwhile the filtering and guiding water tanks and anti-slide wall toes are importantly arranged for slippage prevention of protective bodies. The large unconsolidated soil and stone body slope protection structure and method are suitable for protecting side slopes and slide slopes of unconsolidated soil (stone) bodies.

Description

technical field

[0001] The invention relates to the technical field of slope protection. Background technique

[0002] Small loose soil (stone) body slopes or landslides are not a big problem no matter what protection method is adopted. However, for large or giant slopes, especially landslides, their protection has always been a difficult problem in the field of geotechnical engineering. The reason why it is a difficult problem is because of the following two points: First, the traditional method is often difficult to effectively solve this problem. In the case of heavy rainfall, the protection time is often limited, resulting in the loss of personnel and property. Second, the traditional method can solve the problem but The cost is too high to be realized at all. How to effectively solve these issues is an urgent problem in the field of geotechnical engineering. Contents of the invention

Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing.

[0017] like figure 1 , figure 2 As shown, the large-scale loose soil and stone slope protection structure of the present invention first determines the base surface, and a group of anti-slide piles 2 are fixed on the base surface, and the anti-slide piles 2 are inserted below the base surface, and piled up around the anti-slide piles 2 Block stone net cage masonry 1. The block stone net cage masonry 1 is made of highly water-permeable materials, for example, six net cage pieces are connected to form a cuboid, and stones are filled therein. The cage sheet is made of flexible material, such as nylon material, high-density polyethylene, etc., which has certain strength and toughness, and has good water permeability. One side of block stone cage masonry 1 is the slope to be protected, and the other side is gravel filter layer 4 . Anti-sliding pile 2 can be made of rigid mat...
