Description
Technical field
The present invention relates to a kind of basement supporting and protection structure, be particularly with the main building basement supporting and protection structure of annex.
Background technology
Along with the development of urban construction, highrise building occurs like the mushrooms after rain, and for the highrise building of commercial function, main building is usual and podium is interdependent and build, and main building can be communicated with annex basement.When basement construction, excavation area can be very large, and the tau-effect of cutting the earth on the one hand clearly, can there will be the bad phenomenon such as the earthwork protuberance during shoveling; On the other hand, the time of shoveling can be very long, and the main building construction period can be corresponding very long.Because the main building duration is controlling node, the main building construction period determines delivery time of whole engineering.Construction period can be very long traditionally, and construction safety is difficult to obtain guarantee.
Summary of the invention
The present invention is to provide a kind of main building basement supporting and protection structure with annex, solves the problem of prior art.
For this reason, the present invention arranges interim enclosure wall between basement main building and annex, makes main building basement and annex basement form two independently spaces.Because the main building basement construction time is controlling node, first to construct after interim enclosure wall completes main building basement, main building basement adopts along method construction, namely first to construct basement bottom board, construct from the bottom to top again, to construct again after main building basement roof completes annex basement, annex basement adopts inverse method construction, namely first to construct basement roof, construct from top to bottom again, object is in order to the construction of basement annex does not disturb main building deck to construct, and synchronously carries out main building basement construction during the construction of basement annex.
