Embodiment Construction
[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0037] A deep foundation pit support structure, such as figure 1 As shown, it includes column 1 and supporting wall structure 2. There are eight support wall structures 2 and surround a regular octagon, and the columns 1 have sixteen and are all set vertically.
[0038] Such as figure 2 As shown, each supporting wall structure 2 includes a beam 3 and a baffle 4 , and the thickness of the baffle 4 in the horizontal direction is equal to that of the beam 3 in the horizontal direction. There are four beams 3 and they are arranged horizontally, and there are three baffle plates 4 and they are arranged between two beams 3 . The two ends of the beam 3 beyond the baffle plate 4 form an extended cantilever 5 . The extension cantilevers 5 between two adjacent support wall structures 2 are arranged in a staggered manner, the angle formed by the extension cantileve...

The invention discloses a deep foundation pit supporting structure, and belongs to the technical field of housing construction. According to the key pints of the technical scheme, the deep foundationpit supporting structure comprises vertical columns and five or more vertical supporting wall structures, the number of the vertical columns is twice the number of the supporting wall structures, a polygon is defined by the supporting wall structures, an included angle facing a deep foundation pit and formed by every two adjacent supporting wall structures is greater than 90 degrees, extending cantilevers are arranged on the two sides in the horizontal direction of the supporting wall structures, the extending cantilevers between the adjacent supporting wall structures are arranged in a staggered mode, an included angle formed by each extending cantilever and the corresponding supporting wall structure adjacent to the extending cantilever is a first included angle, the vertical columns arearranged in the first included angles, and the extending cantilevers and the supporting wall structures both abut against the side walls of the vertical columns. The deep foundation pit supporting structure has the effect of more conveniently mounting and demounting pipes.
Description
technical field [0001] The invention relates to the technical field of house construction, more specifically, it relates to a deep foundation pit support structure. Background technique [0002] Deep foundation pit refers to a project where the excavation depth exceeds 5 meters (including 5 meters), or the depth does not exceed 5 meters, but the geological conditions, surrounding environment and underground pipelines are particularly complicated. Deep foundation pit support refers to the support, reinforcement and protection measures adopted for the side wall of deep foundation pit and the surrounding environment in order to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. [0003] At present, the Chinese invention patent with the notification number CN205742224U discloses a deep foundation pit support construction structure based on row piles and anchor cables, including a pile row support structure for suppo...
