Dynamic direction slidably connects clump weight 41, and linkage lead screw 42 is threadedly coupled with clump weight 41.
When feed screw 37 drives sliding rack 32 and anchor rod main body 34 moves, the foundation pit support system entirety center of gravity can be made
Position shift, to cause what bottom plate 13 cannot stablize to be supported on the bottom surface of soft base landform foundation pit.Feed screw
37 during rotation, by driving gear 43 and driven gear 44, linkage lead screw 42 is driven to rotate.Meanwhile it being intermeshed
Driving gear 43 and 44 rotation direction of driven gear on the contrary, make feed screw 37 and link lead screw 42 rotate direction on the contrary,
To make sliding rack 32 and clump weight 41 move in the opposite direction.The foundation pit support system is adjusted using clump weight 41 integrally to weigh
The position of the heart prevents 13 stress of bottom plate unstable and run-off the straight, can play the role of improving stability.
Specific implementation mode：Foundation pit side-wall is supported using support stake 11, bottom of foundation ditch is supported using bottom plate 13, energy
It effectively prevent supporting stake 11 to sink caused by the soil property of bottom of foundation ditch is excessively soft.Actuating sleeve 23 is rotated by handle 24,
Actuating sleeve 23 drives the telescopic rod 22 being threadedly coupled with it sliding in telescopic 21, and bottom plate 13 is made to be rotated on holder 12, from
And realize the angle adjusted between support plate 14 and bottom plate 13, support plate 14 and bottom plate 13 can be enable to touch the side wall of foundation pit respectively
And bottom wall, play the role of improving stability.Feeding motor 36 drives feed screw 37 to rotate, and feed screw 37 drives sliding rack
32 and anchor rod main body 34 move, so that augers 35 is abutted with foundation pit side-wall.Anchor pole motor 33 drives anchor rod main body 34 to rotate, and makes
Augers 35 pierces foundation pit side-wall, to which automatic anchor pole 31 is squeezed into foundation pit side-wall.Sliding rack is driven in feed screw 37
While 32 movement, drive linkage lead screw 42 to rotate by the transmission of driving gear 43 and driven gear 44, make clump weight 41 to
Opposite direction movement, so as to adjust the foundation pit support system entirety center of gravity, and then can effectively improve the foundation pit support system
Stability.
