Description

Technical Field

[0001] The utility model belongs to the technical field of brick fetal membranes, in particular to a structure for enhancing the stability of brick fetal membranes. Background Art

[0002] Brick formwork is a method of using brick masonry to replace wooden formwork or steel membrane board for formwork. It is mainly used in places where the side formwork is not easy to remove, such as basement foundations and pedestals. In foundation pit projects, in order to bury the raft foundation of the main building and the foundation of equipment such as elevators, the large foundation pit is usually dug deeper to form a "pit in a pit". At present, the side formwork of the drop-deep foundation in the "pit in a pit" widely uses brick formwork constructed in the pit as the base layer of external waterproofing and the side formwork of the drop-deep foundation. However, conventional brick wall structures are difficult to meet the needs of deeper and deeper foundations. The brick formwork cannot withstand the pressure of the backfill soil and collapses from time to time. Therefore, we proposed a structure to enhance the stability of the brick formwork. The pit side engineering piles are connected to the brick formwork ring beam by planting reinforcement to increase the brick formwork's ability to resist tilting, so as to achieve the purpose of high efficiency and cost saving.
