Abstract

The invention discloses an urban operation subway heaving control structure and a control method thereof. The urban operation subway heaving control structure comprises a plurality of uplift piles, a bottom-carrying cable pipe and back pressure prestressed tendons, wherein the uplift piles are buried in foundation pits to be excavated on the two opposite sides of an underground structure of an operation subway correspondingly, and the burial depth of the pile tops of the uplift piles is located between the top burial depth and the bottom burial depth of the underground structure; the bottom-carrying cable pipe is supported at the bottom of the underground structure, and the two ends of the bottom-carrying cable pipe are connected to the upper parts of the uplift piles on the two opposite sides of the underground structure correspondingly; the back pressure prestressed tendons abut against the upper part of the underground structure, and the two ends of each back pressure prestressed tendon are connected to the upper parts of the uplift piles on the two opposite sides of the underground structure correspondingly. According to the urban operation subway heaving control structure, the problems that new building products developed on the two sides of an operated metro station easily cause upheaval or settlement of an operated metro structure, and the safety of the operated metro structure is seriously affected are solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an urban operation subway heave control structure and a control method thereof. Background technique [0002] Under the background that urban land resources are becoming increasingly scarce and rail transit promotes urban development, enhancing the charm of hub nodes is the key to increasing the value of land along the line. The station space is no longer simply used as a mobile space connecting the station body and the city, but a burden to reflect the city. characteristic role. As a result, a high-end business district with a station-city integration complex centered on public transport hubs and stations has gradually been derived. [0003] New construction products are developed on both sides of the already operating subway stations, and the foundation pits of new construction products are excavated and unloaded on both sides of the operating subway. Therefore,...
