Prestressed grid anchorage technology for side slope governance

Abstract

The invention relates to prestressed grid anchorage technology for side slope governance, in particular to a prestressed grid anchorage structure for side slope governance and a construction method thereof. Pressure dispersion type anchor ropes are adopted, and each two anchor ropes are butted and tensioned with steel stranded wires from vertical, horizontal and opposite anchor holes in a middle part so as to save outer anchor pier and tension repeatedly. The non-bonded steel stranded wires are longitudinally and transversely crossed and arranged to form a grid, and a node is an anchorage endor a tensioning end. The composite side slope anchorage structure is simple and convenient to construct, overcomes the defects that the prior reinforced concrete framework beam anchorage structure iseasy to crack and deform, is difficult to construct and the like, and makes full use of the strength of the high-strength and low-looseness non-bonded steel stranded wires to combine the light and flexible tensioned grid and the pressure dispersion type anchor ropes into a whole so as to obtain more effective and safer anchorage effect. Moreover, the side slope governance and green ecological protective measures are combined.

Description

technical field [0001] The invention relates to the engineering technology of side slope stability treatment, and in particular provides a prestressed grid anchoring technology for side slope treatment. Background technique [0002] At present, with the large-scale infrastructure construction in our country, the slope stability management project occupies a considerable proportion in the construction and maintenance management projects of highways, railways, reservoir dams, etc. In recent years, various types of slope landslide accidents have occurred one after another. Therefore, the technical requirements for slope treatment projects are getting higher and higher. Generally speaking, the technical level of slope engineering that has been treated and has not been treated is still relatively low compared with foreign countries, including survey, design, construction and safety monitoring and forecasting. As for the combination of slope management and green environmental prot...

Problems solved by technology

High-strength steel strands are connected in series with ordinary reinforced concrete beams, and the material strength does not match, resulting in waste of materials

And the section of the frame beam 8 is relatively large, 40-60cm. In addition to adding extra self-weight load, the disadvantage of this method is that the force system is not reasonable, the construction is difficult, and the cost is high, thus limiting its application range
