Technical Field

[0001] The utility model relates to the technical field of I-shaped oblique bracing support devices, and specifically, to an I-shaped oblique bracing support device for a deep foundation pit. Background Art

[0002] The foundation pit is a soil pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings on site, and waterproofing and drainage work should be done. During the construction of the foundation pit, inclined support equipment is required to support the walls around the foundation pit. During use, the existing deep foundation pit I-shaped inclined support device supports the walls around the foundation pit through inclined supports, and the inclined supports in the deep foundation pit have a large inclination and need to be supported by a protective frame. However, due to the different inclination angles of the inclined supports in the foundation pit, the protective frame cannot effectively support the inclined supports, which is inconvenient to use and cannot meet the use requirements.

[0003] After searching, the Chinese patent announcement number is CN218322779U, which discloses a deep foundation pit I-shaped diagonal brace support device. In this patent, by setting threaded holes and support bolts, when the protective frame supports the middle part of the diagonal brace, the staff can rotate the support bolts to make the support bolts move along the threaded holes toward the protective frame and contact with it, so that the protective frame can support the diagonal brace, which is convenient to use and meets the use requirements;
