Example 1
As shown in fig. 1-4, the present embodiment provides a foundation pit supporting device, which includes at least 1 group of baffles 110 and a supporting mechanism disposed between the at least 1 group of baffles 110, wherein the supporting mechanism includes at least 4 threaded rods 120, sleeves 130 are slidably disposed at two ends of the threaded rods 120 along a length direction thereof, blind holes 210 are disposed at edges of the baffles 110, and handles 220 are disposed at end surfaces of the blind holes 210 on the baffles 110. The sleeve 130 is provided with a connector 410 which is in clearance fit with the blind hole 210 of the baffle plate; an adjusting nut 140 for adjusting the position of the sleeve 130 is provided at the threaded rod 120.
In use, the baffles 110 are placed at two side walls of the foundation pit, then the threaded rod 120 is placed between the two baffles 110, the adjusting nut 140 is rotated, the connector 410 at the sleeve 130 extends into the baffles 110, and the baffles 110 are supported by the threaded rod 120 and the sleeve 130, so that the support of the side walls of the foundation pit is completed.
The foundation pit supporting device in the embodiment supports the baffle 110 by arranging the supporting mechanism at the edge of the baffle 110, so that the supporting of the side wall of the foundation pit is realized, and the foundation pit supporting device is compared with the conventional common foundation pit supporting device, and the supporting mechanism cannot interfere the construction of staff at the bottom of the foundation pit, so that the smooth progress of foundation pit construction is facilitated. And after the construction is finished, the adjusting nut 140 is loosened, and then the connector 410 is pulled out of the blind baffle hole 210 to complete the disassembly of the foundation pit supporting device, so that the foundation pit supporting device is convenient to install and disassemble by staff.
Referring to fig. 3 and 4, the inner wall of the blind hole 210 expands to form a bar-shaped groove 310, the end of the connector 410 is provided with a protruding block 420 in clearance fit with the bar-shaped groove 310, the bottom end of the blind hole 210 expands outwards to form a limit groove 320, and the end of the protruding block 420 can extend into the limit groove 320 and rotate in the limit groove 320.
