Wide-span deep buried metro station structure designed through combination of Y-shaped column and anti-pulling pile

Abstract

The invention belongs to the field of underground engineering construction, and particularly relates to a wide-span deep buried metro station structure designed through the combination of a Y-shaped column and an anti-pulling pile. The wide-span deep buried metro station structure is characterized in that the bifurcated top of the Y-shaped column is connected to a top board beam, the middle part of the Y-shaped column is connected with a middle board beam, the lower end of the Y-shaped column is connected with a bottom board beam, the top end of the anti-pulling pile is connected with the lower surface of a bottom board, and the anti-pulling pile is arranged in the Y-shaped column span of the bottom board. The top part bifurcated fulcrum of the Y-shaped column is adopted to design the metro deep buried underground structure to reduce the top board span of the underground structure, the bottom board span is reduced by means of the bottom board anti-pulling pile, a design method for the wide-span user space between the top and bottom boards is created, under the condition that the engineering cost is not increased, the structure force bearing of the top board and the bottom board is reasonably solved and the problem of dense columns and nets in the use space of passengers is solved, and thus improving the use comfortableness of the station.

Description

technical field [0001] The invention belongs to the field of underground engineering construction. The invention relates to a structure for designing a large-span deep-buried subway station in combination with a Y-shaped column and an uplift pile, specifically referring to the use of the top fork of the Y-shaped structural column in the design of the underground structure of the subway. The fulcrum reduces the span of the roof of the underground structure, and uses the floor uplift piles to reduce the span of the floor, thereby creating a design method for a larger span between the roof and the floor. Background technique [0002] With the rapid development of cities and the tight supply of land, more and more attention has been paid to the need for underground space. At present, most major cities in the country are building or planning to build subways. [0003] With the expansion of subway construction scale, there are more and more deeply buried underground stations. Usua...
