The Method of Bundling and Mobile Modeling of Ultra-Long Reinforcement Bars in Deep and Narrow Shafts Without Supports

Abstract

The invention relates to a non-bracket overlong steel bar binding mobile molding method of a deep-narrow vertical shaft. A liftable hanging scaffold is taken as a work platform to complete the laying of a reinforcing mesh and the mounting of a lining combined steel mold, wherein the reinforcing mesh is formed by binding vertical reinforcements from top to bottom for a time; the lining combined steel mold is formed by movably assembling steel forms from bottom to top to complete casting. Compared with the prior art, the non-bracket overlong steel bar binding mobile molding method provided by the invention effectively solves the prominent problems of high lining construction difficulty, low efficiency and easiness of occurrence of safety accidents of an existing deep-narrow vertical shaft by adopting a simple optimized design; as a result, the efficient and safe operation in the deep-narrow vertical shaft is realized, the cycle period is greatly reduced, the construction progress is accelerated and the work quality is highly guaranteed; accordingly, the economic cost input to the work is reduced; the non-bracket overlong steel bar binding mobile molding method of the deep-narrow vertical shaft is applicable to popularization and application in the related fields such as corresponding deep-narrow vertical shaft lining construction.

Description

technical field [0001] The invention relates to the technical field of underground engineering construction, in particular to a mobile mold building method for bundling ultra-long steel bars without supports in deep and narrow shafts. Background technique [0002] At present, in the construction of deep shaft lining, the amount of concrete is relatively small. Among them, the sliding form construction is basically not used because of its cumbersome manufacture, inconvenient assembly and disassembly, large investment and high cost; traditionally, floor-standing construction is generally used. Scaffolding is used as the second lining construction operation platform, and combined formwork is used for shaft lining construction. This method is relatively cost-effective and flexible in operation, and is widely used. The operation of deep and narrow shafts often cannot be effectively implemented because of the narrow operating space of such deep and narrow shafts. When the existin...
