Modularized enclosure cage structure and construction method

Abstract

The invention discloses a modularized enclosure cage structure and a construction method and belongs to the field of bridge construction. The modularized enclosure cage structure mainly comprises a plurality of enclosure cage units and a plurality of crawling ladder units, wherein the plurality of enclosure cage units and the plurality of crawling ladder units are arranged around a bridge pier inan enclosed and closed manner by surrounding the bridge pier in the circumferential direction and being overlapped in multiple layers. The modularized enclosure cage structure has the advantages that1, partial assemblies and single members of the modularized structure can be customized by manufacturers and can be rapidly assembled to be conveniently hoisted in place; 2, the bottom of the enclosure cage structure in the bottom layer is tightened with a plurality of anchoring bolts embedded in a concrete foundation, four corners of the top of the enclosure cage structure in the top layer are fixed by being stayed by a cable and a ground anchor so that the enclosure cage structure can resist strong wind load and is suitable for river, sea, coastal and land constructions; and 3, as the enclosure cage structure is combined with a crawling ladder, the structure is compact and modularized enclosure cage structure is convenient for operators to go up and down and do operations. Therefore, themodularized enclosure cage structure has the advantages of convenient assembling, high universality, safety, reliability, low cost and so on; and by being combined with the corresponding constructionmethod, the modularized enclosure cage structure has the advantages that the structure can be repeatedly used, the stability is high, the energy is saved, the emission is reduced, and the economic benefits and social benefits are obvious.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a modular bridge pier cage structure and a construction method. Background technique [0002] The construction of land and water bridge piers, especially high bridge piers, requires scaffolding as a working platform. At present, the most widely used scaffolds are fastener or bowl-buckle scaffolds assembled from multiple rods, and some combined scaffolds, such as portal scaffolds, etc. . Fastener-type or bowl-buckle-type scaffolding is currently the most widely used and widely used type of scaffolding due to its flexible disassembly and assembly, convenient transportation, and strong versatility; however, this type of scaffolding has poor safety assurance and low construction efficiency. However, some combined scaffolds, such as portal scaffolds, still have defects such as low rigidity, easy deformation during transportation and use, poor versatility, and short service life, so...

Fastener-type or bowl-buckle-type scaffolding is currently the most widely used and widely used type of scaffolding due to its flexible disassembly and assembly, convenient transportation, and strong versatility; however, this type of scaffolding has poor safety assurance and low construction efficiency. However, some combined scaffolds, such as portal scaffolds, still have defects such as low rigidity, easy deformation during transportation and use, poor versatility, and short service life, so it is difficult to meet the needs of bridge construction.
