The telescopic mechanism 4 is telescopic along the axial direction (refer to the left-right direction shown in fig. 1) of the support 3, so that when the telescopic mechanism 4 is axially extended, the telescopic mechanism 4 drives the support 3 to move in a direction away from the support top plate 2, so as to increase the distance between the support top plate 2 and the support base plate 1; when the telescopic mechanism 4 is axially contracted, the telescopic mechanism 4 drives the support 3 to move toward the direction approaching the support top plate 2 to reduce the distance between the support base plate 1 and the support top plate 2.
In particular, referring to the left-right direction shown in fig. 1, the support substrate 1 and the support top plate 2 are set to be opposite to each other in the left-right direction, the support 3 and the telescopic mechanism 4 are set in sequence in the left-right direction and are both located between the support substrate 1 and the support top plate 2, the left end of the support 3 is connected to the support substrate 1, the right end of the support 3 is connected to the left end of the telescopic mechanism 4, and the right end of the telescopic mechanism 4 is connected to the support top plate 2.
For example, when a foundation pit with a larger supporting size is required, that is, when the foundation pit has a larger size in the direction from the supporting base plate 1 to the supporting top plate 2, the telescopic mechanism 4 may be extended in the axial direction at this time, so that the telescopic mechanism 4 drives the supporting member 3 to move leftward, thereby increasing the distance between the supporting base plate 1 and the supporting top plate 2, and thus, the foundation pit with a larger size may be supported.
For example, when a foundation pit with a smaller supporting size is required, that is, when the size of the foundation pit in the direction along the supporting substrate 1 to the supporting roof 2 is smaller, the telescopic mechanism 4 may be contracted in the axial direction at this time, so that the telescopic mechanism 4 drives the supporting member 3 to move rightward, thereby reducing the distance between the supporting substrate 1 and the supporting roof 2, and thus, the foundation pit with a smaller size may be supported.
In summary, according to the foundation pit supporting structure provided in this embodiment, by setting the supporting element 3 and the telescopic mechanism 4, the telescopic mechanism 4 can drive the supporting element 3 to move towards the direction away from the supporting top plate 2 when axially extending so as to increase the distance between the supporting top plate 2 and the supporting base plate 1, or drive the supporting element 3 to move towards the direction close to the supporting top plate 2 when axially contracting the telescopic mechanism 4 so as to reduce the distance between the supporting top plate 2 and the supporting base plate 1, thereby being applicable to foundation pits with different sizes and improving the application flexibility.
