Introduction of highway slope protection types?

Why do construction enterprises carry out highway slope protection in highway slope protection construction? What about the infrastructure? The following is the basic introduction of slope protection of Zhong Da Consulting and Finishing Expressway:

Highway engineering refers to the survey, measurement, design, construction, maintenance and management of highway structures. Highway engineering structures include subgrade, pavement, bridge, culvert, tunnel, drainage system, safety protection facilities, greening and traffic monitoring facilities, as well as service facilities such as houses and workshops for construction, maintenance and monitoring.

Introduction of highway slope protection types;

Slope protection types and reinforced slope protection types are divided into biological protection and masonry protection. Biological protection includes vegetation concrete, grass planting, turf laying and tree planting. Masonry protection block stone slope protection and facing wall, rhombic grid slope protection, hexagonal hollow brick slope protection, window rib slope protection and shotcrete slope protection. The reinforcement types are divided into toe wall, anti-slide wall, anti-slide pile, prestressed anchor cable, grouting anchor rod reinforcement and drainage reinforcement.

Related expansion of highway slope protection types;

There are many factors affecting slope stability, which can be summarized into two categories, namely natural factors and human factors. Natural factor highway is a special belt structure, and each highway has to cross many areas. Due to the influence of geological structure and topographic conditions, each small area has different geological and climatic conditions, so the natural factors affecting slope stability include geological, topographic, climatic and hydrological conditions.

Human factors The construction and service life management of a highway are all realized by people. According to the construction procedure and content and the situation of the built highway, the human factors affecting the slope stability can be divided into design factors, construction factors and maintenance management factors. Key points and main construction technology of slope protection reinforcement: block stone slope protection and facing wall block stone slope protection are divided into mortar wall and dry wall, which have certain thrust resistance compared with slope protection. Its advantage is that it can use local materials and its technology is simple, but it is too heavy to be suitable for high slopes. Rhombic grid slope protection Rhombic grid slope protection can be prefabricated, cast-in-place concrete and masonry. Grass can be planted in simple grid, but it is only suitable for filling, which is not conducive to slope stability. You should choose carefully. Shotcrete slope protection adopts shotcrete grouting anchor rod to reinforce some weathered rocks of high slope. Simply put, it is a method of injecting cement slurry into the stratum and adding some additives to change the physical and mechanical properties of soil and rock mass, and adding a reinforcement cage or tendon, that is, an anchor column, when necessary to stabilize the slope. The construction equipment is simple, the occupied area is small, the construction period is short, and the effect is quick. The depth of the reinforced stratum can be deep or shallow, but it is difficult to detect the grouting range and judge the consolidation state. Drainage consolidation Drainage consolidation is mainly used for slope reinforcement with more groundwater on the slope. Its methods include dendritic blind ditch, plastic drainage pipe slope and earthwork excavation slope.
