Description

Technical Field

[0001] The invention relates to the technical field of foundation pit enclosure, in particular to a foundation pit enclosure and diagonal brace connection structure. Background Art

[0002] The foundation pit is ensured to be stable during the construction process by setting up a retaining and supporting system. The retaining is set up around the foundation pit, which can reinforce the soil and prevent the collapse around the foundation pit, playing a stabilizing role. The support system supports the retaining through the purlin, and the other end of the support system is fixed inside the foundation pit to play a supporting role.
