THE APPLICATION OF THE KEY TECHNOLOGY OF THE SINGLE-SIDE FORMWORK OF THE EXTERNAL WALL OF THE BASEMEN
Land resources are scarce in modern cities,and the narrow construction site has become a common problem,and the construction quality of basement exterior walls is becoming more and more popular to the attention of the participating units.In the underground outer wall structure edge line is small from the foundation pit enclosure,according to the traditional method of double-sided formwork support and reinforcement of the outer wall Under the working condition,the construction safety risk of waterproofing in the narrow semi-enclosed space after support is large,and the backfill in the later stage can not be tamped.The backfill is sinking.This can lead to the destruction of the waterproofing layer and increase the risk of leakage on the exterior wall.The unilateral formwork support system of the steel frame formwork can save the construction period,and has the advantages of simple installation,low cost,good impermeability and other characteristics.Combined with the special working conditions of the unilateral formwork support system,this study analyzes the key to the management of single-sided formwork support from the perspective of technical quality and management.Technical problems,put forward the key problems that are prone to occur in construction,conduct detailed analysis,and give solutions.
