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...

Abstract

The invention relates to the field of buildings, and provides an underground structure upper soil body construction system and method. The underground structure upper soil body construction system comprises a dewatering well, a plurality of engineering piles, a simulation analysis system, a field data monitoring system and a regulation and control system, wherein the regulation and control system regulates and controls the water level of the dewatering well, so that the actual vertical lifting deformation value of the underground structure in the unloading process of the upper soil body of the underground structure is smaller than or equal to the simulated vertical lifting deformation value simulated by a simulation analysis system. The regulation and control system is used for regulating and controlling the water level of the dewatering well in real time in the unloading process of the upper soil body of the underground structure by combining effective data acquired by a field data monitoring system and the simulated precipitation depth value and the simulated vertical lifting deformation value simulated by the simulation analysis system, the actual vertical lifting deformation value of the underground structure is smaller than or equal to the simulated vertical lifting deformation value, the vertical lifting deformation amount of the underground structure does not exceed the specified allowable range all the time, and stability and safety of the underground structure are guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a soil construction system and method for the upper part of an underground structure. Background technique [0002] The shortage of land resources brought about by urban development makes the limited land resources need to be fully utilized, and the development and utilization of underground space has become an important development trend. In the development of underground space, the foundation pit project often straddles the existing underground structure (such as the subway tunnel); the excavation and unloading of the foundation pit above the existing underground structure will inevitably have an impact on the existing underground structure. Specifically: the excavation process of the upper soil of the existing underground structure is actually a process of unloading the upper soil of the existing underground structure, which will inevitably cause the gap between ...
