Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing.

[0026] figure 1 A first embodiment of the soil reinforcement fiber 10 according to the invention is schematically shown. Such as figure 1 As shown, the soil reinforcement fiber 10 includes a linear fiber body 1 and a plurality of beads 2 arranged on the fiber body 1 at intervals.

[0027] After soil reinforcement fiber 10 is mixed with plain soil 50 to form fiber soil (as Figure 4 As shown), a plurality of fiber bodies 1 can be overlapped with each other, and beads 2 of different soil reinforcement fibers 10 can be entangled with each other to form a three-dimensional network. The three-dimensional network can make it difficult for the soil particles 51 to move, which shows that the cohesion between the soil particles is stronger macroscopically. After the fiber net soil is used to construct the roadbed, the soil particles of the roadbed (or other structures) are diffi...

Abstract

The invention discloses a soil body reinforcement fiber, a roadbed and a roadbed construction method. The soil body reinforcement fiber comprises a linear fiber body and a plurality of bead bodies arranged on the fiber body at intervals. The soil body reinforcement fiber is added into pure soil to form a roadbed. Slopes of the roadbed have high overall stability. Accordingly, the roadbed can resist scouring of rainwater.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a fiber for reinforcing soil. The invention also relates to a roadbed constructed from such a reinforced soil body and a method for constructing the roadbed. Background technique [0002] Usually, railways, highways, especially high-speed railways, expressway embankments, and roadbed slopes of road cuttings are very prone to landslides, slides and other diseases under the erosion of rainwater. In the northwestern region where the vegetation is poorly developed, this situation is even more serious, and it may even cause damage to the foundations of high-speed railways and highways, seriously affecting the safety of vehicles. Contents of the invention [0003] In view of the above problems, the present invention proposes a soil reinforcement fiber. After adding the soil reinforcing fiber of the present invention to the plain soil and constructing the roadbed, the side slope of ...
