Preferably, the actuator is circumferential several cylinders that guide rod side is arranged in, the piston rod of the cylinder
It offsets with the bottom of portable pillar.
By using above-mentioned technical proposal, by setting cylinder for actuator, the piston rod promotion of cylinder be can be achieved with
The lifting of motion bar.
Preferably, the locating rod is provided with four, and four locating rods are equally arranged with motion bar.
By using above-mentioned technical proposal, four locating rods are uniformly distributed in motion bar surrounding, can keep preferable
Simplify structure while structural stability, and achievees the purpose that reduce overall structure weight.
Preferably, the activity interval is the through slot of width and support rod equivalent width.
By using above-mentioned technical proposal, by setting activity interval to the through slot of width Yu support rod equivalent width,
It can be avoided support rod to swing in activity interval, improve the stability of support rod.
Preferably, the one side of the support plate towards foundation pit side-wall is arcwall face.
By using above-mentioned technical proposal, arcwall face can adapt to the abutting of foundation pit side-wall, to improve the branch to foundation pit
Support effect.
Preferably, the support plate is rubber slab.
By using above-mentioned technical proposal, buffering effect can be played, support plate is avoided to damage the side wall of foundation pit.
In conclusion the utility model has the following beneficial effects:
After foundation pit is opened up and is finished, it is only necessary to support construction be put into the center of bottom of foundation ditch, then pushed away by cylinder
Dynamic portable pillar rises, and the one end of support rod far from portable pillar can be rotated by activity interval, so that support rod is connected with
One end of support plate moves to support plate diagonally downward and offsets with foundation pit side-wall, it will be able to fast implement the support to foundation pit.
