Embodiment Construction
[0061] The following is attached figure 1 to attach Figure 12 The present invention is further described in detail with specific examples.
[0062] The system and method for constructing the upper soil of an underground structure in this embodiment are not limited to tunnels, but can also be applied to other types of underground structures, such as underground structures such as subway stations and basements.
[0063] The unloading of the upper soil body applicable to the upper soil mass construction system and method of the underground structure in this embodiment is not limited to the excavation form of the foundation pit 2, and can also be other forms of soil mass unloading methods, for example, in the upper part of the underground structure The soil is unloaded by drilling.
[0064] Such as image 3 As shown, the underground structure in this embodiment takes a two-way tunnel as an example, and the unloading construction of the upper soil body takes soil excavation con...
