Description
Technical field
The utility model relates to a kind of civil construction structure more particularly to a kind of constructing structures of external hanging type wind pavilion.
Background technique
Metro Station Structure is generally divided into station main structure and accessory structure, wherein accessory structure be generally divided into wind pavilion and
Two class of entrance needs just to need first to apply at this time in the longitudinally parallel setting in main body foundation pit side when wind pavilion uses external hanging type
Do wind pavilion foundation pit carry out again wind pavilion structure return build.External hanging type wind pavilion is generally basement one structure, and excavation of foundation pit depth is general
In 10m or so, width comprehensively considers economy and safety majority in 6~10m, design using engineering method stake building enclosure, together
Shi Shixian sealing effect, is typically provided with twice inner support, and support is respectively arranged at that engineering method stake is gone along with sb. to guard him and former main structure is gone along with sb. to guard him
Crown beam and pile body between.In water-rich sand layer ground, the resultant force that the load that engineering method stake is gone along with sb. to guard him is Water And Earth Pressures is acted on, by
Small in level of ground water height, active earth pressure, hydraulic pressure load will account for very at high proportion.
Branch will be lost by needing to cut the inner support that original is gone along with sb. to guard him pile body, but is arranged at this time when wind pavilion structure progress structure is returned and built
Support point, common way is to stay to set post-cast strip between wind pavilion structure and main structure in engineering, first carry out part backplane, side wall and
Returning for top plate is built, and as support is gradually removed in the construction of part-structure, is then cut pile body between post-cast strip and is hung out, finally carries out
Post-cast strip pours, and completes entire wind pavilion structure time and builds.Such arrangement and method for construction causes pile body to cut time-consuming since post-cast strip space is small
Work consuming and safety is poor, while structure longitudinal direction construction joint is increased, easily lead to later period percolating water.
