Embodiment Construction

[0039] The following is attached Figure 1-8 The application is described in further detail.

[0040] The embodiment of the application discloses a deep foundation pit enclosure structure. Such as figure 1 and figure 2 , the deep foundation pit enclosure structure includes a number of concrete piles 1 distributed along the periphery of the foundation pit, the concrete piles 1 are arranged in a rectangular shape, and a reinforcement cage 11 is pre-embedded in the concrete pile 1, which is used to increase the strength of the concrete pile 1, and the reinforcement cage 11 It is cylindrical, and the reinforcement cage 11 includes vertical bars 112 and horizontal bars 111. There are several vertical bars 112 distributed along the circumference. A crown beam 2 is connected to the top, and the concrete piles 1 corresponding to the row are connected in series to improve the support effect of the concrete piles 1 on the soil.

[0041] The vertical bars 112 in each concrete pile 1...

Abstract

The invention relates to a deep foundation pit support structure and a construction method thereof, and belongs to the technical field of foundation pit support. The deep foundation pit support structure comprises a plurality of concrete piles distributed along the periphery of a foundation pit, reinforcement cages are pre-buried in the concrete piles, the reinforcement cages comprise transverse ribs and vertical ribs, the vertical ribs penetrate out of the concrete piles, top beams are arranged on the concrete piles, and each top beam comprises a plurality of building blocks, each building block is provided with a through hole allowing the vertical rib to be inserted therein, the vertical ribs are fixed to the building blocks through first connecting pieces, and every two adjacent building blocks are fixed through second connecting pieces. According to the deep foundation pit support structure, the structure has the effects of saving resource waste, and being green and energy-saving.

Description

technical field [0001] The present application relates to the field of foundation pit protection technology, in particular to a deep foundation pit protection structure and a construction method thereof. Background technique [0002] The foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, and the support, reinforcement and protection measures adopted for the side wall of the foundation pit and the surrounding environment. [0003] The Chinese patent with the notification number CN210712863U discloses a foundation pit enclosure structure, which includes a side retaining structure for the foundation pit. , a second crown beam is constructed on the side of the first crown beam far away from the foundation pit, and a number of prestressed anchor cables are stretched between the first crown beam and the second crown beam; An anchor-stay foundation is provided, and the anchor-stay foundati...
