Main building basement support structure with podium

Abstract

The invention discloses a basement supporting structure of a main building with a podium building. The basement supporting structure is characterized in that a temporary enclosure wall is arranged between the main building and the podium building, and two high-pressure jet grouting piles are arranged on each of the outer sides of the joints between a main building enclosure wall and a podium building enclosure wall, so that the problem of water seepage at the positions weak in seepage-proof performance is solved; two high-pressure jet grouting piles are used at each of the trough-section seam positions of the main building enclosure wall, the podium building enclosure wall and the temporary enclosure wall for seepage-proof seam filling, and two high-pressure jet grouting piles are also arranged at each of the corner positions of the main building enclosure wall and the podium building enclosure wall; steel plate water-stop belts are arranged at the cross positions of the main building enclosure wall, the podium building enclosure wall and the temporary enclosure wall, a circular-ring brace is arranged on the inner side of the main building enclosure wall, and angle braces are arranged between the circular-ring brace and the main building enclosure wall and are made of concrete or steel; a truss supporting system is arranged in the middle of the main building enclosure wall, supporting columns are arranged on the lower portions of truss girders so as to maintain stability in a plane, concrete outlets are formed in a top plate of the podium building, and flanging beams are arranged at four corners of the concrete outlets additionally.

Description

technical field [0001] The invention relates to a support structure for a basement, in particular to a support structure for a basement of a main building with a podium. Background technique [0002] With the development of urban construction, high-rise buildings have sprung up like mushrooms after rain. For high-rise buildings with commercial functions, the main building is usually built next to the podium, and the basement of the main building and the podium will be connected. The excavation area will be very large during basement construction. On the one hand, the space-time effect of excavation will be obvious, and unfavorable phenomena such as earthwork uplift will occur during excavation; on the other hand, the excavation time will be very long, and the construction period of the main building will be correspondingly long. long. Since the construction period of the main building is a controlling node, the construction period of the main building determines the deliver...
