[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0019] like Figure 1 As shown in Figure 5, the utility model provides a support device for a deep foundation pit in construction, including a first support structure 10 and a second support structure 20;

[0020] The first supporting structure 10 and the second supporting structure 20 each include two plate bodies 31 and a supporting rod 32. Two supporting rods 32 are arranged between the two sides of the two plate bodies 31. The two ends of the supporting rods 32 are rotatably connected to the two plate bodies 31 respectively. The supporting rods 32 are adjustable. The upper ends of the two plate bodies 31 of the first supporting structure 10 are respectively provided with fixing nuts 34, and the lower ends of the two plate bodies 31 of the second supporting structure 20 are provided with connecting screws 35.

[0021] During the operation, the length of the support rod 32 is adjusted according to the width of the foundation pit 1, so that the spacing between the plates 31 corresponds to the width of the foundation pit 1, and the two plates 31 in the first support structure 10 are placed at the bottom of the foundation pit 1, and the two plates 31 are respectively in contact with the inner wall of the foundation pit 1, and then the support rod 32 in the second support structure 20 is adjusted to a corresponding length, so that the two plates 31 in the second support structure 20 are placed on the upper ends of the two plates 31 in the first support structure 10, and then the connecting screw 35 is screwed into the fixing nut 34 to connect the first support structure 10 and the second support structure 20 together. When the depth of the foundation pit 1 becomes shallower, the connecting screw 35 is screwed out of the fixing nut 34 to separate the second support structure 20 from the first support structure 10, and the second support structure 20 is taken out of the foundation pit 1. When the depth of the foundation pit 1 becomes deeper, the second support structure 20 is connected to the first support structure 10 through the cooperation of the connecting screw 35 and the fixing nut 34. In this way, the amount of support structure can be reduced or increased, and the flexibility is high.

[0022] Preferably, the support rod 32 includes a first rod body 321, a second rod body 322 and a cylinder body 323, and the first rod body 321 and the second rod body 323 are both provided with a plurality of connecting holes 324, and both ends of the cylinder body 323 are respectively provided with insertion holes 325, and the insertion holes 325 at both ends respectively cooperate with the plurality of connecting holes 324 on the two rod bodies.

[0023] When the length of the support rod 32 needs to be adjusted, the first rod body 321 and the second rod body 322 are moved into the cylinder body 323, or moved outward from the cylinder body 323. After the length of the support rod 32 is adjusted, the bolts 326 are inserted into the corresponding connecting holes 324 from the insertion holes 325 at both ends of the cylinder body 323, and then the nuts 327 are screwed on the two bolts 326 respectively, so that the length of the support rod 32 is fixed at the adjusted length position.

[0024] Preferably, the connecting screw 35 is disposed on a fixing plate 351 , and the fixing plate 351 is connected to the plate body 31 .

[0025] Preferably, fixing nuts 34 are further disposed on the upper ends of the two plates 31 of the second supporting structure 20 .

[0026] By setting fixing nuts 34 at the upper ends of the two plates 31 in the second supporting structure 20, the supporting structure can be connected again at the upper end of the second supporting structure 20, so that when the depth of the foundation pit 1 becomes deeper, the number of supporting structures can be further increased.

[0027] Preferably, a plurality of conical columns 51 are respectively disposed at the lower ends of the two plates 31 of the first supporting structure 10 .

[0028] When the two plates 31 of the first support structure 10 are placed at the bottom of the foundation pit 1, the two plates 31 are pressed downward so that the conical columns 51 at the lower ends of the two plates 31 are respectively inserted into the bottom of the foundation pit 1, further increasing the stability of the first support structure 10 at the bottom of the foundation pit 1.

[0029] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
