The base net assembly is connected to the base plate assembly and fits the inner wall surface of the foundation pit to play a supporting role inside the foundation pit.

[0023] It can be known that when the substrate assembly is assembled, it will be placed at the bottom of the foundation pit. The substrate assembly can place the base grid assembly in a preset position. The preset position can be understood as the base grid assembly being in a relatively stable state, and will not cause the bottom of the foundation pit to tilt or shift in position due to soft soil. The number of base grid assemblies can be one or more, and the connection method between the base grid assembly and the substrate assembly can be in the form of welding or bonding, or it can be simply placed on the substrate assembly. The base grid assembly can effectively prevent the soft soil from collapsing into the foundation pit.

[0024] See also Figure 1 In some embodiments, the base mesh assembly includes a plurality of mesh plates 3, which are connected to form a receiving cavity having an opening at one end, and the mesh plates 3 are attached to the inner wall surface of the foundation pit and the base plate assembly.

[0034] It can be known that the crushed stone layer 6, the backfill soil layer 7, the steel bar layer 9 and the concrete layer 10 can all improve the overall strength of the foundation. The separation layer 8 can be made of waterproof material, which can prevent moisture from seeping from the upper part of the foundation to the bottom of the foundation pit, and prevent the soil at the bottom of the foundation pit from becoming soft again, thereby improving the overall stability of the foundation.

[0035] See also Figure 3 In some embodiments, the steel bar layer 9 is formed by a plurality of steel bars tied into a mesh structure, and the concrete layer 10 fills and wraps the steel bar layer.

[0036] It can be known that the concrete layer 10 can be directly poured into the steel layer 9, and after pouring, the concrete layer 10 can wrap the steel layer 9, in which case the overall strength can be improved.

[0037] From the above description, it can be known that the foundation auxiliary device and foundation provided by the utility model maintain the base net component in a preset position through the base plate component.
