Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a force transmission device which utilizes an underground continuous wall as a permanent force transmission belt. Background Art

[0002] During the construction of a group pit in a soft soil area, when the overall area of the foundation pit is large or the requirements for surrounding environmental protection are high, the foundation pit will generally be divided into multiple pits for sequential construction. The partition walls between the foundation pits are generally underground continuous walls. The partition walls here need to be demolished only after the basement structures on both sides are constructed to zero.

[0003] Traditional construction methods generally use the structural base plate as the force transmission belt, and often set up force transmission steel sections, which leads to an unstable connection between the force transmission belt and the underground continuous wall, which can easily cause the underground continuous wall to collapse and damage the foundation pit.
