Ground anchor structure of cable-stayed buckling and hanging cable hoisting system and construction method

Abstract

The invention discloses a ground anchor structure of a cable-stayed buckling and hanging cable hoisting system and a construction method. The ground anchor structure of the cable-stayed buckling and hanging cable hoisting system comprises a lower weight and an upper weight arranged at the top of the lower weight, wherein the upper weight comprises a plurality of weight layers which are verticallystacked together; each weight layer comprises a fence arranged on the periphery of the weight layer and a soil body filled in the fence; the fence is formed by piling ecological bagged soil; a geogridis further arranged on the edge of each weight layer; and the geogrids are folded on the upper surfaces of the weight layers after wrapping the fences from the lower surfaces of the weight layers. According to the ground anchor structure, the soil body upper weight is adopted, the effect of the ground anchor structure is the same as that of a traditional concrete upper weight, earthwork excavatedby a foundation pit is reused to replace concrete for weight, a large amount of materials are saved, the construction cost is low, and the workload of later ground anchor disassembly and the influence on the surrounding environment can be reduced.

Description

technical field [0001] The invention relates to the field of cable hoisting construction, in particular to a ground anchor structure and a construction method of a cable-stayed buckle-hanging cable hoisting system. Background technique [0002] In the cable-stayed buckle-hanging cable hoisting system, it is necessary to build a large underground anchor structure (referred to as "ground anchor"), which is used to fix the load-bearing rope, hoisting rope and traction rope in the cable hoisting system. And buckle cables during the installation of arch ribs, etc. The ground anchor structure forms include gravity type, pile anchor type and anchor cable type, etc., and the commonly used ground anchor structure is gravity type. Gravity ground anchor includes lower ballast and upper ballast, in which the lower ballast is located below the ground and is mainly reinforced concrete or plain concrete structure, while the upper ballast is located above the lower ballast and is mainly pl...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a cable-stayed buckle-hanging cable hoisting system ground anchor structure for the problems in the prior art that the ground anchor adopts concrete upper weight, the amount of poured concrete is large, the construction cost is high, and it is inconvenient to dismantle later. The construction method, the ground anchor structure adopts the pressure on the soil body, the construction cost is low, and after the cable hoisting system is completed, the demolition workload is small, and the surrounding environment is not affected
