Abstract

The invention discloses an ultra-deep support-free locking notch ring beam in sea areas and relates to the technical field of engineering construction. By means of the ultra-deep support-free locking notch ring beam in sea areas, the problems that in the prior art, an existing vertical shaft locking notch ring beam is small in construction operation profile and small in depth, and the waterproof design cannot meet the waterproof requirement of coastal regions are solved. The ultra-deep support-free locking notch ring beam in sea areas comprises a first support, a second support, a first locking notch ring beam body and a second locking notch ring beam body. The first support comprises a first side slope, a second side slope and a dual-layer jet grouting pile, wherein the first side slope and the second side slope are connected and supported by the dual-layer jet grouting pile and both adopt side slope supporting. The first support and the second support are arranged symmetrically. The first locking notch ring beam body and the second locking notch ring beam body are arranged between the first support and the second support. The first locking notch ring beam body is adjacent to the first support. The second locking notch ring beam body is adjacent to the second support.

Description

technical field [0001] The invention relates to the technical field of engineering construction, and more specifically relates to an ultra-deep unsupported locking ring beam in sea areas. Background technique [0002] In the construction of existing tunnel shafts, lock ring beams are often set as the early support form of shaft construction. The lock mouth ring beam can prevent wellhead collapse and ensure the safety of subsequent excavation personnel. [0003] The existing locking ring beam is composed of two symmetrically arranged side slope supports and two locking rings, and the two locking rings are arranged between the two side slope supports, and the locking rings are supported and connected by the bottom The bottom support and the top support protruding from the bottom support constitute. [0004] However, the slope of the existing lock ring beam has only one slope and the lock ring structure is simple, so that the construction work section is small and the depth i...
