Problems solved by technology

[0005] 1. Regardless of whether it is cast-in-place or prefabricated, the cost of labor input is quite expensive;
[0006] 2. The cost of cast-in-place concrete or prefabricated blocks is high;
[0007] 3. The construction progress is slow, time-consuming and labor-intensive, and it is easy to cause safety and quality hazards, and small-area collapses are prone to occur during the construction process;
[0009] 5. Operators need to work on the slope with heavy loads for a long time, and the safety risk is high

Embodiment 1

[0079] This embodiment provides a roadbed slope protection structure, wherein, the schematic diagram of the roadbed slope protection structure is as follows figure 2 and image 3 shown, from figure 2 and image 3 It can be seen that it includes coconut fiber blanket 1, barbed wire 2, mixed base material 3 and several anchor rods 5;

[0080] The coconut fiber blanket is used to be fixed on the roadbed slope, and a planting board 4 is arranged between the coconut fiber blanket and the wire mesh, for supporting the wire mesh and making the wire mesh spaced from the coconut fiber blanket preset distance;

[0081] A plurality of anchor rods can be distributed on the roadbed slope at intervals, and the first end of the anchor rod is inserted into the roadbed slope anchor hole 6 (with a diameter of 5 cm) along the direction perpendicular to the roadbed slope , the distance between the first end of the anchor rod and the bottom of the embankment slope anchor hole is 10cm, and th...

Embodiment 2

[0096] This embodiment provides a high liquid limit soil subgrade slope protection treatment process, wherein the high liquid limit soil subgrade slope protection treatment process uses the subgrade slope protection structure provided in Example 1, and the process includes the following specific steps :

[0097] Fabrication of roadbed slope protection structure:

[0098] Step 1. High liquid limit soil subgrade slope leveling: leveling the slope to be constructed before construction to remove protruding stones and other sundries;

[0099] Step 2. Coconut fiber blanket laying: start from the landfill layer at the top of the slope and spread it smoothly from top to bottom. Use U-shaped rivets to fix the coconut fiber blanket on the slope at the top of the slope, and sew and splice the joints at the head and tail. Or overlap 4cm-8cm and fix it with rivets. The newly laid coconut fiber blanket should be placed underneath when lapping. The rivets used for lapping and fixing are U-s...

Abstract

The invention provides a roadbed slope protection structure, and a manufacturing method and application thereof. The roadbed slope protection structure comprises a coconut fiber blanket, a metal net,a mixed substrate and a plurality of anchor rods, wherein the coconut fiber blanket is used for being fixed onto a roadbed slope; a support body is arranged between the coconut fiber blanket and the metal net, and is used for supporting the metal net and enabling the metal net and the coconut fiber blanket to form a preset distance; the plurality of anchor rods can be distributed on the roadbed slope at intervals; the first end of each anchor rod is inserted into a corresponding anchor hole of the roadbed slope, and the second end of each anchor rod sequentially passes through the coconut fiber blanket and the metal net and is connected with the metal net; and a gap between the coconut fiber blanket and the metal net is fully filled with the mixed substrate, and the mixed substrate extendsonto the metal net. The roadbed slope protection structure provided by the invention uses the coconut fiber blanket and a metal net for substrate spraying and seeding; two layers of anti-flushing protection can be effectively formed on the slope surface; the stability of the high-liquid-limit soil roadbed slope is further and favorably improved; and meanwhile, the improvement effect of the roadbed slope protection structure on the soil is very obvious.

Description

technical field [0001] The invention relates to a roadbed slope protection structure, a manufacturing method and application thereof, and belongs to the technical field of roadbed slope protection. Background technique [0002] With the vigorous development of my country's economy, the construction of expressways has gradually developed to hilly areas. High liquid limit soil is the most common type of bad soil in hilly areas. It is widely distributed in Guangxi, Yunnan, Sichuan, and Guizhou in my country. , Guangzhou, Fujian, Jiangsu, Anhui and more than 20 provinces. The engineering characteristics of high liquid limit soil are as follows: wide distribution area, complicated causes, high liquid-plastic limit, and high natural water content, because of its low permeability, high fine particle content, micro-expansion, low water immersion strength, and water stability. These engineering characteristics of high liquid limit soil lead to high liquid limit cutting slopes, regard...
