Problems solved by technology

However, in recent years, with the rapid development of high-speed and railways, the climate environment has changed. Due to the simple structure and poor hydrophobicity of the conventional skeleton protection structure, when there is a change in cold and heat, cracks may appear on the concrete surface, and the types of planted vegetation are single. keep getting eliminated

Embodiment 1

[0021] The overall skeleton is built with M7.5 mortar masonry rubble 6. The outer arch 1 and the inner lattice structure are arranged in the same vertical row. The two types of inner lattice arches are arranged alternately along the vertical row. The arch frame 1 is blocked by the ground beam, and at the same time, anchor rods 5 are set on the ground beam for reinforcement. The average length of each frame is 2500mm. The planting area of ​​the first diamond-shaped inner lattice structure is 800mm long, and the thickness of the diamond-shaped concrete prefabricated block is 150mm. 7. Plant turf.

[0022] The linear inner lattice structure is 150mm wide, and the outer arch frame 1 is divided into three areas. Different types of turf are planted in each part. Each vertical row of skeletons is blocked by ground beams. The width of the ground beams is 600mm, and the distance between the skeletons along the slope is 600mm. The lower side slope platform is 2000mm long, and the draina...

Abstract

An anchor rod and ground beam grouted rubble lattice slope protection combined structure comprises outer arch frames and inner lattices, the two arch frames with different inner lattices and the sameouter arch frame are separated through ground beams, the rest of the arch frames are covered with M7.5 grouted rubbles, and a whole slope framework is reinforced through anchor rods. A drainage ditchadopts a trapezoidal design, and a 5% lime soil cushion is cushioned below the drainage ditch. By means of the structure, the anchor rod, ground beam and lattice slope protection structure for slope restoration is stable in structure and high in landscape performance, fully exerts reduction of the rainwater flow speed by the framework and fixation of plants to soil, can effectively protect stability of a slope, and can also save cost.

Description

technical field [0001] The invention relates to a combination structure for slope protection of ground beams with anchor rods and masonry rubble, which is suitable for the field of rock slope protection construction in open-pit mines. Background technique [0002] The skeleton protective structure is a spatial structure with a certain window pattern geometry and size, which is artificially constructed with masonry materials such as mortar rubble or concrete. The soil is reinforced to prevent shallow instability caused by rainfall, wind, and climate. However, in recent years, with the rapid development of high-speed and railways, the climate environment has changed. Due to the simple structure and poor hydrophobicity of the conventional skeleton protection structure, when there is a change in cold and heat, cracks may appear on the concrete surface, and the types of planted vegetation are single. problems and are constantly eliminated. Contents of the invention [0003] I...
