Slope Strengthening Method Using High Performance Shotcrete

Abstract

The present invention relates to an integrated slope strengthening method using high-performance sprayed concrete and reinforcing parts, that is, after ordinary concrete with a compressive strength of 21 to 30 MPa can be produced in a concrete mixing plant and transported to the construction site, mixed with the volume relative to 20-40% air bubbles to increase fluidity, form ordinary strength shotcrete, high performance shotcrete, colored shotcrete, that is, mixed with one of fly ash and slag powder or mixed fly ash Low-grade mixed materials made of slag powder to form ordinary-strength shotcrete, mixed with silica fume and metakaolin or advanced mixed materials made of silica fume and metakaolin to form high-performance shotcrete, mixed with oxidation Colored sprayed concrete can be formed by coloring materials such as iron or carbon black, so that the inner layer, outer layer, and surface layer can be sequentially constructed on the slope, so that construction costs can be reduced and high strength and durability can be ensured. Make maintenance easy.

Description

technical field [0001] The present invention relates to a slope strengthening method, and in more detail, relates to an integrated slope strengthening method using high-performance sprayed concrete and reinforcing components, that is, ordinary concrete with a compressive strength of 21-30 MPa can be produced in a concrete mixing plant and fed to the After transfer to the construction site, in the state of increasing the fluidity by mixing 20-40% air bubbles relative to the volume, ordinary strength shotcrete, high performance shotcrete, and colored shotcrete are formed respectively, that is, mixed with fly ash or slag fine powder One of the low-grade mixed materials formed or mixed with fly ash or slag fine powder to form ordinary-strength shotcrete, mixed with one of silica fume and metakaolin to form or mix silica fume and metakaolin. materials to form high-performance shotcrete, and coloring materials such as iron oxide or carbon black are mixed to form colored shotcrete, s...

Problems solved by technology

[0009] Usually, the above-mentioned construction methods are selected by comprehensively considering the use of the slope surface, soil and rock properties, foundation conditions, maintenance conditions, and landscape properties. However, until now, only the functionality has been emphasized, and the landscape features have been ignored, resulting in many damages to the surrounding landscape.

[0010] In order to pay attention to the above-mentioned scenery, artificial rocks are fabricated and installed on the slopes that are existing structures. However, the artificial rocks need to be attached to the outside of the slope for construction, and it is necessary to install and connect the artificial rocks inside the slope. A support member that supports artificial rocks, the inner side of the artificial rocks is coated with a binder, and a primer is used to form an artificial rock slab, but this does not have structural properties

[0011] Also, the artificial rock mainly uses epoxy or polymer as the main binding material, so when the artificial rock is exposed to ultraviolet rays, the brittleness of the artificial rock becomes stronger, resulting in a significant decrease in durability, so it usually has a service life of 3 to 4 years. Years, so periodic maintenance is required, and there is a problem that it is difficult to maintain
