A reinforcement construction method for channel-shaped slab platforms in operating subway stations

Abstract

The invention discloses a reinforcing construction method for a trough plate platform of an operation subway station and belongs to the technical field of reinforcing construction of operation subwaystation structures. The reinforcing construction method comprises the following steps of S1, construction applying and blockage of a track line, S2, construction preparation, S3, hole forming, S4, mounting of steel bars, S5, mounting of steel formworks, S6, stirring of cement foundation grouting materials, S7, pouring of the cement foundation grouting materials and pressurizing of a high funnel, S8, platform surface recovering and S9, applying of construction completion and removing of line blockage. According to the reinforcing construction method for the trough plate platform of the operation subway station, the two holes with the diameter being 90 mm are formed in a trough plate and serve as the pouring hole and the pressurizing hole correspondingly, and not only can the integrity of the overall structure of the trough plate platform and the safety of the operation station be guaranteed, but also the reinforcing construction requirements can be met; the assembled steel formworks areutilized as a part of the reinforcing structure, and convenience and rapidness are achieved; and the reinforcing construction method has the advantages that safety is high, operation is convenient, applicability is high, and manual operation strength is reduced.

Description

technical field [0001] The invention relates to a reinforcement construction method for a channel-shaped slab platform of an operating subway station, which is used for the structural reinforcement construction of an operating subway station, and is especially suitable for the reinforcement construction of a trough-shaped slab platform for an operating subway station, which can well meet the safety of the operating subway and the reinforcement of the station structure quality, belonging to the technical field of subway station structure reinforcement construction. Background technique [0002] When the bearing capacity of the channeled slab platform of the operating subway station is not enough, it needs to be reinforced. The general reinforcement effect is not good, and the safety risk is high, and the channeled slab reinforcement construction of the operating subway station can only be carried out within three hours after the subway is out of service. , choosing convenient...

[0002] When the bearing capacity of the channeled slab platform of the operating subway station is not enough, it needs to be reinforced. The general reinforcement effect is not good, and the safety risk is high, and the channeled slab reinforcement construction of the operating subway station can only be carried out within three hours after the subway is out of service. , choosing convenient operation, ensuring the quality of reinforcement and the safety of the channel plate structure are the top priorities for channel plate reinforcement in operating subway stations. Reasonable selection of reinforcement technology is the key to ensuring project quality and operational safety. Therefore, how to choose how to strengthen the operation Ease of operation, guarantee of reinforcement quality, safety of channel plate structure and safety of subway operation are the issues that our engineers and technicians need to face
