The invention provides a large
pipe shed guide wall structure of an underground excavation tunnel and a construction method of the large
pipe shed guide wall structure. The large
pipe shed guide wall structure comprises a guide wall located outside an underground excavation tunnel portal, large pipe shed pre-buried sleeves arranged in the circumferential direction of the arch portion of the inner edge of the guide wall at intervals and longitudinally penetrate through the guide wall, and a large pipe shed constructed from the large pipe shed pre-buried sleeves to
bed rock at the top of an underground excavation tunnel body, wherein the guide wall and a open-
cut structure
fender post are arranged in a nested mode, the width of the guide wall is equal to the
diameter of the open-
cut structure
fender post, main ribs of the open-
cut structure
fender post are anchored and integrally cast to form a whole, the guide wall is supported on the open-cut structure fender post, and the open-cut structure fender post is fixedly fixed in a rock-soil layer below in an embedded mode. According to the large pipe shed guide wall structure of the underground excavation tunnel and the construction method, the large pipe shed guide wall structure is good in integrity, clear in force transmission path, space-saving, safe and reliable, the influence on the main body structure of a working well can be reduced by constructing the guide wall and the large pipe shed in advance, the large pipe shed guide wall structure of the underground excavation tunnel and the construction method can be used for arranging large pipe shed guide walls of subways, railways and municipal subsurface tunnels, and is high in practicability and good in generalizability.
