Abstract

The invention provides a protection method of a high slope of a road, and belongs to the technical field of highway civil work safety. The method comprises the steps of (1) high slope trimming, (2) anchor rod construction, (3) foundation excavation and steel bar colligation, (4) formwork building, (5) concrete pouring, (6) frame beam maintenance and formwork dissembling, (7) grass seed seeding, and (8) slope surface maintenance management, wherein concrete comprises 180-250 parts by weight of cement, 300-400 parts by weight of gravel, 200-320 parts by weight of river sand, 5-7 parts by weightof cotton fiber, 50-80 parts by weight of fly ash, 15-30 parts by weight of active carbon and 100-150 parts by weight of water. The method can well protect the high slope, and is simple, convenient and quick; a built protection facility has high cracking resistance and freezing resistance; and when the high slope of the road is protected, a large space is not occupied, and the attractiveness of the high slope is not influenced.

Description

technical field [0001] The invention belongs to the technical field of road civil engineering safety, and in particular relates to a method for protecting road high side slopes. Background technique [0002] In road construction, due to the large height difference between urban roads and the surrounding terrain due to topography, high slope roadbeds are often formed. With the development of my country's economy, people's demand for road construction is also increasing. Due to the high slope and road Therefore, the protection of high slopes plays an important role in road protection. Usually, geological, hydrological and climatic conditions are the main factors affecting the stability of high road slopes. In response to these factors, people have gradually developed various protection technologies for high slopes, including plastering and beating the surface, planting plants, soil Nail support technology, prestressed anchor technology, anti-slide pile technology and retaining...
