Special lifting appliance for dual-I-shaped water-permeable framework

Abstract

The invention discloses a special lifting appliance for a dual-I-shaped water-permeable framework, relates to a novel bunching fixed-point throwing lifting appliance for a dual-I-shaped water-permeable framework, and particularly relates to a lifting appliance for suspending the water-permeable framework for realizing the purpose that the framework can fall off automatically. The special lifting appliance for the dual-I-shaped water-permeable framework consists of an upper truss, a lower truss and bolts, wherein the upper truss and the lower truss are combined to form an integral structure; the upper truss comprises an upper truss framework, upper truss cross beams, upper truss bolt holes, upper truss spacing pipes, upper truss lifting buckles and upper truss spacing rings; the upper truss framework is a Sudoku-shaped framework formed through welding I-shaped steel; the upper truss cross beams are welded below the upper truss framework; the upper parts of the upper truss cross beams are positioned in the middles of the squares on two sides, and are welded with the two upper truss lifting buckles; the upper truss spacing rings are welded below the upper truss cross beams; the upper truss bolt holes are formed in the upper truss framework, and are welded with four upper truss spacing pipes; the lower truss comprises a lower truss framework, lower truss cross beams, lower truss bolt holes, lower truss spacing pipes, lower truss lifting buckles and lower truss spacing rings.

Description

technical field [0001] The special sling for duplex-shaped permeable frames of the present invention relates to a sling for fixed-point throwing in groups of novel duplex-shaped permeable frames, and in particular to a sling for hanging the permeable frames and automatically falling off. Background technique [0002] In waterway improvement projects, laying interlocking row construction underwater is one of the most commonly used methods to prevent water erosion and protect the river bed, and has the best bottom protection effect. However, due to the influence of various factors such as tide, water depth, water flow velocity, and flow direction, the underwater paving construction will form various flows such as cross-dive flow, flow along the embankment, and flow around the embankment. state, causing the gold-plated blanket surface of the embankment to be scoured, which has an impact on the stability and safety of the structure. Although soft row protection is laid around t...

Problems solved by technology

[0004] In order to ensure the effect of protecting the beach and bottom of the project, the role of the traditional concrete tetrahedral permeable frame can no longer meet the needs of the project, so a method that can better improve the water flow structure near the bottom and protect the area is developed. A new type of permeable frame that can form better energy dissipation and beach protection effects, has better stability, durability and economy, and is convenient for construction

[0005] At the same time, for the new permeable frame researched, traditional manual throwing can no longer give full play to its own advantages, so only fixed-point throwing can realize its own value
