Title:
CONSTRUCTION STRUCTURE FOR COMMUNICATION AND CONNECTION BETWEEN NEWLY ADDED MINED CHANNEL AND EXISTING STATION HALL LAYER
Document Type and Number:
WIPO Patent Application WO/2021/223573
Kind Code:
A1
Abstract:
A construction structure for communication and connection between a newly added mined channel and an existing station hall layer (1). A reinforcing ring beam (21) and a newly added surface layer (107) are provided at a connection port of a newly added mined hall (2), such that the newly added underground hall (2) communicates with and is connected to the existing station hall layer (1). Reinforcing structure main bars (109) and a reinforcing structure stirrup (110) are arranged in the reinforcing ring beam (21) and the newly added surface layer (107). A bonding agent is applied at an old-structure side of a new-old structure interface (104) so as to improve bonding between the old structure and the newly added structure. The connection structures are connected in a horizontally symmetrical manner, such that the connection between the structures is stable and aesthetically pleasing, and the effective connection between the new connection structure and the old connection structure ensures consistency between the new and old structures. The connection port is effectively and stably connected by means of the newly added reinforcing ring beam (21) and the newly added surface layer (107), thereby ensuring that no protrusion or water seepage occurs during subsequent use.
