Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a template supporting structure for a wall body at an underground continuous wall in a basement. Background Art

[0002] The underground continuous wall is a foundation project that uses a trenching machine on the ground to dig a long and narrow deep trench along the peripheral axis of the deep excavation project under the condition of mud wall protection. After the trench is cleared, a steel cage is suspended in the trench, and then underwater concrete is poured using the conduit method to form a unit trench section. This process is carried out section by section to build a continuous reinforced concrete wall underground as a water interception, anti-seepage, load-bearing and water retaining structure.

[0003] A basement refers to a room whose floor is more than half of the room's clear height below the outdoor ground level. Multi-story and high-rise buildings require a deeper foundation. To make use of this height, a basement is built under the ground floor of the building. This can not only increase the usable area, but also save the backfill soil in the center of the house, which is relatively economical. Building a basement below the ground floor of a house can improve the efficiency of building land use. Some high-rise buildings have a great burial depth, and making full use of this depth to build a basement has both good economic and usage effects.

The walls of the basement need to be supported by formwork during construction. The traditional formwork support method is double-sided mold clamping. However, double-sided mold clamping will make the formwork on one side close to the underground continuous wall, which will lead to a narrow space that is not conducive to formwork support construction. After the wall is cast, it is extremely inconvenient to remove the formwork. There will be a gap between the wall and the underground continuous wall, which is difficult to meet the construction requirements and has many defects.
