Fabricated vertical shaft barrel structure and design and construction method

Abstract

The invention discloses a fabricated vertical shaft barrel structure and a design and construction method thereof. The fabricated structure of each layer starts from lap joint inserting ribs, then dense rib column steel bars are bound, lower annular beam steel bars are bound, double-wall-plate standard components are hoisted in place and sequentially assembled into a ring to form a vertical shaftbarrel of the current layer, upper annular beam steel bars are bound, joint bars are reserved at the positions of the upper-layer dense rib columns, annular vertical inner cavity beam column concreteis poured, and a triangular truss scaffold is installed. Compared with a traditional underground deep vertical shaft barrel structure design and the construction method, the fabricated vertical shaftbarrel structure has the advantages that main components and parts are industrially prefabricated in a factory, the standardization degree is high, machining is accurate, production efficiency is high, product quality is easy to guarantee, traditional formworks are replaced with prefabricated parts, an assembly structure is not limited by a working face, an environment-friendly construction mode is achieved, construction is convenient and fast, work efficiency is high, lap joint of all procedures is smooth, no complex staggered support or scaffold system exists on a construction site, and safeand civilized construction is guaranteed.

Description

technical field [0001] The invention relates to the technical field of design and construction of a shaft body structure in civil engineering, in particular to an assembled shaft body structure and a design and construction method. Background technique [0002] With the development of our country's society and economy, the available space on the urban ground is becoming increasingly tight, and the cost of house structure demolition and surface shallow pipeline relocation has risen sharply. The development and utilization of underground space can alleviate traffic congestion, reduce urban air pollution, and improve urban ecological environment. increasingly becoming a social consensus. Underground construction projects such as subways, underground comprehensive pipe corridors, and underground sewage transportation tunnels have become hot spots for a new round of infrastructure investment and construction. The cylinder structure has high rigidity, integrity, good water-retain...
