Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a deep foundation pit supporting device. Background Art

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Construction engineering includes factories, theaters, hotels, shops, schools, hospitals, and residences, etc., to meet people's needs for production, residence, study, public activities, etc. Construction engineering has the unity of comprehensiveness, sociality, practicality, technology, economy, and architectural art. Compared with the scope of construction engineering, the scope of construction engineering is relatively narrow. It specifically refers to the installation of various types of buildings and their ancillary facilities and supporting lines, pipelines, and equipment, so it is also called housing construction engineering. According to the different construction environments, auxiliary devices need to be adjusted according to the construction environment, so various types of auxiliary devices are derived. Among them, the foundation pit engineering mainly includes the design and construction of the foundation pit support system and earthwork excavation. It is a highly comprehensive system engineering. It requires close cooperation between geotechnical engineering and structural engineering technicians. The foundation pit support system is a temporary structure, which is no longer needed after the underground engineering construction is completed. The foundation pit and foundation trench are both used to build the foundation of the building, but the plane shape is different. The foundation pit is square or close to square, the foundation trench is long and sometimes quite long. What you need to grasp is the difference in their shapes. The foundation pit refers to a foundation pit with a bottom area of ​​27 square meters or less (not 20) and the long side of the bottom is less than three times the short side. The foundation trench refers to a trench with a bottom width of 3 meters or less and the length of the trench is greater than 3 times the width. In other words, the general definition of a deep foundation pit is: a bottom area of ​​27 square meters or less (not 20) and the long side of the bottom is less than three times the short side, the excavation depth exceeds 5 meters (including 5 meters) or there are more than three basement floors (including three floors), or the depth does not exceed 5 meters, but the geological conditions, surrounding environment and underground pipelines are particularly complex.

[0003] A Chinese patent discloses a deep foundation pit support device, the publication number of which is CN207160019U. The deep foundation pit support device is proposed in the article. Although a plurality of reinforced concrete piles are pre-buried at intervals around the inner side of the deep foundation pit to be excavated, a plurality of prefabricated reinforced concrete blocks are arranged from top to bottom between the outer sides of each two adjacent reinforced concrete piles and the edges of the deep foundation pit. The length of the prefabricated reinforced concrete blocks is greater than the spacing between the two adjacent reinforced concrete piles. This deep foundation pit support device enables the plurality of prefabricated reinforced concrete blocks to form a retaining wall inside the plurality of reinforced concrete piles, effectively supporting and protecting the surrounding geological structure sections from beginning to end, and can continuously carry out foundation pit excavation construction, effectively solving the phenomenon of disturbance and quicksand collapse during continuous excavation construction of shotcrete support construction, and ensuring the construction period, quality and safety. However, when facing the two sides inside the deep foundation pit, it is necessary to adjust the inclined surfaces of different angles to resist the possibility of collapse on both sides. The use of a square structure is not conducive to the support of the walls on both sides, and the utilization is relatively limited. Utility Model Content
