Net-shaped supporting and retaining structure of deep soil filling slope

Abstract

The invention relates to the technical field of deep soil filling slope support, and discloses a net-shaped supporting and retaining structure of a deep soil filling slope. The structure comprises a plurality of vertical steel pipes, a plurality of transverse steel pipes and a plurality of inclined steel pipes, wherein the vertical steel pipes are embedded into a slope body along the slope top of the slope to the slope surface of the slope, the transverse steel pipes and the inclined steel pipes are embedded into the slope body from the slope surface of the slope, and the vertical steel pipes, the transverse steel pipes and the inclined steel pipes are subjected to high-pressure grouting respectively to form solidification slurry. The steel pipes are inserted into the slope body and the slope top of the deep soil filling slope from different directions, so that the net-shaped supporting and retaining structure is formed, the steel pipes in three different directions improve the overall stress of the net-shaped supporting and retaining structure, and the bearing capacity of the structure is improved. In addition, pipe bodies of the steel pipes are subjected to high-pressure grouting, so that the effect of reinforcing soil filling is achieved, and the supporting structure with high strength and rigidity is formed. The purposes of supporting and retaining the slope are achieved while the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of deep fill slope support, in particular to a mesh support structure for deep fill slopes. Background technique [0002] In new construction, it is often necessary to fill and level the fill, which will form a fill slope. The structure of the fill slope is loose, and it is prone to collapse during heavy rain or vibration, which has brought great losses to production and construction. Thick fill slopes can be supported by row pile structures or prestressed anchor cables, but for deep fill slopes with greater thickness, cement mixing piles are often used for reinforcement in engineering construction. [0003] At present, the reinforcement treatment of cement mixing piles is to spray cement into the filling soil through the mixing machine and mix it. The soil and cement are mixed to produce a series of physical and chemical reactions, so as to solidify the filling soil and achieve the purpose of support. [0...
