Construction method of composite ecological slope protection with assembled anchor rod arch skeleton

Abstract

The invention relates to a construction method for assembled type anchor rod and arch framework combined type ecological slope protection. The method mainly comprises the following steps of construction of anchor rods, excavation of a foundation trench, installation of an arch framework, pouring of connecting bands, tensioning of the anchor rods and transplanting of glass blankets. The construction method has the following characteristics and the beneficial effects that arch rings and arch columns of the arch framework are prefabricated, anchor rod holes and connection ribs are reserved on the prefabricated arch columns and arch rings, the prefabricated arch columns and the prefabricated connection ribs of the prefabricated arch rings are welded together and provided with the anchor rods, concrete is poured into the connecting bands, and therefore the integrity and stability of the arch framework are ensured, field assembly of the arch framework and the anchor rods is also achieved, stability is high, and the construction efficiency is high. A built-in type three-dimensional road foundation drainage system is formed, and the drainage effect is good. The ecological glass blankets are arranged on the bare soil parts in the arch rings and pressed firmly through outwards protruding structures of the arch framework, so that protection of the ecological environment and conservation of water and soil are facilitated.

Description

technical field [0001] The invention relates to a composite ecological slope protection construction method, in particular to a composite ecological slope protection construction method with an assembled anchor bar arched skeleton. [0002] technical background [0003] With the rapid development of my country's transportation industry, the number of high-fill roadbed constructions is increasing. Due to the particularity of the high-fill subgrade itself, the subgrade is prone to landslides, which has a great impact on the safe driving of vehicles. Therefore, higher requirements are put forward for the slope protection of high fill embankment. [0004] Traditional slope protection methods generally use hard materials such as cement, stone, and concrete as the main building materials, and consider slope stability from a mechanical point of view in design. Traditional slope protection can be roughly divided into shallow protection slope protection, stone masonry slope protecti...

Problems solved by technology

Although the traditional anchor arched skeleton slope protection is conducive to improving the safety factor of the soil layer and enhancing the stability of the rock slope, this technology greatly reduces the self-weight of the structure, saves engineering materials and ensures the safety and stability of the project, while absorbing It has the advantages of beautiful appearance and convenient greening for the grass-planting protection of the mortar rubble (concrete block) skeleton, but the traditional arched skeleton slope protection is cast-in-place, and the drainage system is not perfect. It is difficult to construct the high-fill roadbed, and the slope protection is easy to drain Unsmooth leading to slope protection instability
