The existing foundation pit support device is generally composed of a base, an angle adjustment component and a side panel. Although the support of the angle adjustment component can adapt to the adjustment of the side panel at different angles, the side panel generally adopts a whole panel structure with a fixed height.

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0024] like Figure 1-3 As shown, the utility model proposes a foundation pit support device for construction engineering, including a base 1 and a side plate. The base 1 is fixed to the ground by ground nails 11. A support frame 2 is provided at the right end of the base 1. The support frame 2 includes two support rods and two connecting rods 34. The bottom of the support rod is vertically rotatably installed on the base 1. The support rod includes a sleeve rod 32 and a telescopic rod 31 that are slidably sleeved. The sleeve rod 32 is provided with a locking member for fixing the telescopic rod 31. The locking member includes a fastening bolt 33. The fastening bolt 33 passes through the side wall of the sleeve rod 32 and abuts against the telescopic rod 31. By tightening the fastening bolt 33, the telescopic rod 31 after the length is adjusted can be effectively locked and fixed.

[0025] The right side of the sleeve rod 32 and the telescopic rod 31 is provided with a clamping part 30 along its length direction, and the side plate includes a plurality of splicing plates 5 spliced ​​and matched up and down, and the splicing plate 5 is longitudinally provided with a clamping groove 50 near the side of the support rod, and the clamping groove 50 is slidably clamped and matched with the clamping part 30. In this embodiment, the clamping part 30 is a T-shaped structure, and the clamping groove 50 is a T-shaped groove matched with the clamping part 30, so that the splicing plate 5 can be stably clamped on the support rod. In specific implementation, since the telescopic rod 31 is slidably sleeved in the sleeve rod 32, the diameter of the splicing part on the sleeve rod 32 is larger than the splicing part on the telescopic rod 31, and the size of the clamping groove 50 on the splicing plate 5 is larger than the splicing part on the sleeve rod 32, so that the clamping groove 50 on the splicing plate 5 can be effectively clamped on the sleeve rod 32 and the telescopic rod 31.

[0026] According to the depth of the foundation pit during construction, the extension length of the telescopic rod 31 on the support rod is adjusted, and a certain number of splicing plates 5 are vertically installed on the right side of the support rod from top to bottom through the cooperation of the clamping part 30 and the clamping groove 50, so as to adapt to the support use of foundation pits of different depths.

[0027] The bottom of the sleeve rod 32 is fixed with a support plate for supporting and positioning the splicing plate 5 to improve stability. A connecting rod 34 is horizontally fixed between two adjacent sleeve rods 32 and two adjacent telescopic rods 31; the base 1 is fixedly installed with a fixing frame, and two supporting assemblies are correspondingly arranged between the fixing frame and the two connecting rods 34. The supporting assembly includes an adjusting sleeve 21 and two threaded rods 22 with opposite thread directions. One end of the two threaded rods 22 is hinged on the fixing frame and the connecting rod 34 respectively, and the other end of the two threaded rods 22 is threadedly sleeved on both ends of the adjusting sleeve 21 respectively. By rotating the adjusting sleeve 21 in the middle, the two threaded rods 22 are telescoped to change the overall length of the supporting assembly, and then the inclination angle of the supporting frame 2 and the side plate is adjusted, which can adapt to the use in different construction environments.

[0028] The fixed frame includes a U-shaped frame 12 and two cross bars 121. The cross bar 121 is horizontally arranged in the middle of the U-shaped frame 12 and its two ends are slidably sleeved on the vertical part of the U-shaped frame 12. A plurality of adjustment holes 120 are evenly spaced on the vertical part of the U-shaped frame 12. The cross bar 121 is fixed to the U-shaped frame 12 by adjusting bolts 122 and the adjustment holes 120. The ends of the threaded rods 22 are hinged to the corresponding cross bars 121. By changing the height of the cross bars 121 on the U-shaped frame 12 and locking them with the adjusting bolts 122, the support height of the support assembly at the fixed frame end can be adjusted, so that it is more convenient to adjust the support assembly for the support frame 2 and the side panels when they are tilted.

[0029] Sockets are provided on the top and bottom surfaces of the splicing board 5, and a plug-in block 6 is inserted and fixed in the corresponding sockets between the upper and lower adjacent splicing boards 5. The plug-in block 6 includes a positioning portion 61 in the middle and plug-in portions 62 at both ends. The socket includes a groove 51 that cooperates with the positioning portion 61 and a slot 511 provided at the bottom of the groove 51, and the plug-in portion 62 is inserted in the slot 511. The cooperation between the plug-in block 6 and the socket on the splicing board 5 can significantly improve the connection stability between the two adjacent splicing boards 5. In addition, the diameter of the positioning portion 61 in the middle of the plug-in block 6 is larger than the plug-in portion 62, and the positioning portion 61 can just be snapped into the groove 51 of the upper and lower splicing boards 5, which can effectively position the insertion depth of the plug-in block 6.

[0030] A limit plate 4 for limiting the top splicing block is detachably mounted in the middle of the connecting rod 34 on the telescopic rod 31. The limit plate 4 is an L-shaped structure, inserted into the mounting hole opened in the middle of the connecting rod 34, and fixed by the limit bolts on the connecting rod 34. The horizontal part of the limit plate 4 is pressed against the edge of the top splicing plate 5, and the vertical part of the limit plate 4 blocks the front side of the splicing plate 5, thereby effectively limiting and fixing the top splicing plate 5 and improving the structural stability.

[0031] When using the new invention, the base 1 is fixed on the ground, the length of the support rod is adjusted according to the depth of the foundation pit, and a certain number of splicing plates 5 are installed to form side panels, and the sleeve rod 32 and the telescopic rod 31 are fixed by fastening bolts 33, and then the uppermost splicing plate 5 is fixed by the limiting plate 4; then the height of the cross bar 121 on the U-shaped frame 12 and the length of the support frame 2 are adjusted to effectively adjust the inclination angle of the side panel.
