[0033] Embodiment 2

[0034] The difference between this embodiment and Embodiment 1 is that the adjustable support assembly 4 includes a lifting support plate 41, end plates 42, fixed screws 43, openings 44, sleeve plates 45 and rotating nuts 46. A lifting support plate 41 is provided on one side of the support plate 1. A sleeve plate 45 is connected to one side of the lifting support plate 41. Openings 44 are provided on the support plate 1 at positions corresponding to the sleeve plates 45. End plates 42 are connected to both ends of the side wall of the support plate 1 where the openings 44 are located. A fixed screw 43 is connected between the two end plates 42. Rotating nuts 46 are connected to both sides of the outer side wall of the fixed screw 43 where the sleeve plates 45 are located.

[0035] When this embodiment is in use, when the depth of the deep foundation pit is relatively high, first move the sleeve plate 45 along the opening 44. The movement of the sleeve plate 45 drives the lifting support plate 41 to move up and down. When the lifting support plate 41 moves to an appropriate height, stop moving the sleeve plate 45, and then rotate the upper and lower rotating nuts 46 to make them rotate and move along the fixed screw 43. When the two rotating nuts 46 move and fit against the two side walls of the sleeve plate 45, stop rotating the rotating nuts 46. Under the action of the two rotating nuts 46, the sleeve plate 45 can be fixed, and further the lifting support plate 41 can be fixed. Under the action of the lifting support plate 41 and the support plate 1, the support effect of the entire device can be improved.

[0036] The structure and principle of the extension mechanism 3 composed of a support rod, a hinge plate, a telescopic diagonal support plate, a positioning block, a driving handle, a positioning hole, a fixing hole, a positioning strip, and a storage groove in the present utility model have been disclosed in a building deep foundation pit support structure disclosed in Chinese Patent Application No. 202223463439.7. Its working principle is as follows: The support rod is hinged to one side of the middle part of the support plate 1, the support rod is fitted inside the support plate 1, the outer wall of the support rod is parallel to the outer wall of the support plate, the fixed bottom plate 2 and the support plate 1 are connected by a hinge plate, the telescopic diagonal support plate is limited and slides at the bottom inside the support rod, the bottom end of the telescopic diagonal support plate is hinged to the middle end of the top of the fixed bottom plate 2, a positioning block is connected to the outer wall of the support rod, a driving handle is connected to the side wall of the positioning block, the side of the positioning block connecting the support rod penetrates through the outer walls of the telescopic diagonal support plate and the support rod, two sets of symmetric positioning holes are provided on the outer walls of the support rod and the telescopic diagonal support plate, two sets of symmetric positioning strips are fixed on the side of the positioning block connecting the support rod, the positioning strips are inserted inside the positioning holes, a storage groove is provided at the position where the support plate 1 connects the support rod and the fixed bottom plate 2, and the two ends of the support rod and the fixed bottom plate 2 are respectively hinged to the upper and lower ends of the inner wall of the storage groove. When in use, place the support plate 1 on the inner wall of the foundation pit. Then, hold the driving handle and pull out the positioning block from the inside of the positioning hole and insert it into one end of the support rod close to the fixed base. When inserting, make the positioning strip on the bottom surface of the positioning block penetrate into the inner side of the top surface of the support rod, and do not allow the positioning strip to enter the inner side of the telescopic diagonal support plate. Apply a pushing and pulling force to the lower rear side of the support rod, and the fixed bottom plate 2 can be rotated. When the fixed bottom plate 2 rotates, the telescopic diagonal support plate hinged to the top of the fixed bottom plate 2 will slide out from the inside of the support rod, and at the same time, the telescopic diagonal support plate will drive the support rod to rotate, so that the support rod forms an inclined support. When the bottom surface of the fixed bottom plate 2 is in contact with the ground, press the driving handle, press the positioning block to insert the positioning strip into the inner side of the telescopic diagonal support plate, and the support rod and the telescopic diagonal support plate can be supported and fixed.

[0037] Working principle and usage process of the utility model: When the utility model needs to support a deep foundation pit, place the support plate 1 inside the deep foundation pit, and then use the extension mechanism 3 to drive the fixed bottom plate 2 to rotate and unfold to fit the bottom wall of the deep foundation pit. The operator then inserts the hand into the rotation hole and applies force to drive the rotating rod 552 to rotate. The rotating rod 552 drives the rotating screw 553 to rotate. The rotation of the rotating screw 553 drives the threaded sleeve 551 to move. The movement of the threaded sleeve 551 drives the connecting rod 554 to move. The movement of the connecting rod 554 drives the mounting plate 51 to move. The movement of the mounting plate 51 drives the ground anchor 52 to move and be inserted into the bottom wall of the deep foundation pit. Under the action of the ground anchor 52, the fixed bottom plate 2 can be fixed to the ground, ensuring the stability of the placement of the fixed bottom plate 2, and further ensuring the stability of the placement of the entire device, and thus ensuring the support effect of the entire device. When the depth of the deep foundation pit is relatively high, first move the sleeve plate 45 along the opening 44. The movement of the sleeve plate 45 drives the lifting support plate 41 to move up and down. When the lifting support plate 41 moves to an appropriate height, stop moving the sleeve plate 45, and then rotate the upper and lower rotating nuts 46 to make them rotate and move along the fixed screw 43. When the two rotating nuts 46 move and fit the two side walls of the sleeve plate 45, stop rotating the rotating nuts 46. Under the action of the two rotating nuts 46, the sleeve plate 45 can be fixed, and thus the lifting support plate 41 can be fixed. Under the action of the lifting support plate 41 and the support plate 1, the support effect of the entire device can be improved.

[0038] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
