4 ends are connected with circular steel plunger bottom plate 3.Four, 3 surface of circular steel plunger bottom plate angle is equipped with two and sets bolt hole, outermost
Four bolts hole be the positioning bracing piece bolt hole 18 passed through for positioning bracing piece 11, remaining four bolt hole is to be used to connect
Connect the reserved bolt hole 2 of steel arch-shelf 13；
As shown in Figure 2,3, the cylinder barrel 10 is made up of interior casing wall 5, outer casing wall 6, cylinder bottom plate 15, and the outer casing wall 6 is complete
Interior casing wall 5 is covered entirely, and interior casing wall 5, the bottom of outer casing wall 6 and cylinder bottom plate 15 are tightly connected and form cylinder barrel 10；Interior casing wall 5 and outer
Casing wall 6 forms cavity because of sealing；
Four, 15 surface of cylinder bottom plate angle is equipped with two bolts hole 2, and four bolts hole of outermost are to be used to position to add
The positioning bracing piece bolt hole 18 that strong bar 11 passes through, remaining four are to connect the reserved bolt hole 2 of steel arch-shelf 13；
Interior symmetrical inner wall of the casing wall 5 away from bottom 100mm is provided with two row round holes 7 from top to bottom, the circle on interior casing wall 5
Perforate 7 is clogged with round platform rubber stopple 8, the shape of rubber stopple 8 as shown in fig. 7, cylinder barrel 10 built with oil 9；In the cylinder barrel 10
Equipped with 1.5 liters of oil, the volume of the cavity in the cylinder barrel 10 between the volume of charge of oil and interior casing wall 5 and outer casing wall 6 is identical.It is described
The length of round platform rubber stopple 8 is equal with the thickness of interior casing wall 5；
Described 7 liang of row of round hole respectively set 5, and diameter is sequentially reduced from top to bottom, diameter be followed successively by from top to bottom 10mm,
8mm、6mm、4mm、2mm。
So round hole 7 is set to be advantageous in that：For plunger in the presence of external force, extruding oil, oil extrudes each hole again
Plug, because stopple diameter above is bigger than following stopple diameter, when external force is not very big, so stopple is first beaten above
Open, and want that squeezing following stopple then needs bigger external force, so as to improve the bearing capacity of the device.
As a shown in Figure 6, in cylinder barrel 10 of the insertion of circular steel plunger 16 equipped with oil 9, depth 50mm, bracing piece 11 is positioned

15 contact with steel arch-shelf bottom plate 14.The steel arch-shelf bottom plate 14 of the steel arch-shelf 13 is less than circular steel plunger bottom plate 3 and cylinder bottom plate
15。
After installing at the scene, country rock is restrained into footpath, and pressure from surrounding rock is acted on steel arch-shelf, steel arch-shelf 13) extrude and be somebody's turn to do
Device, due to round hole 7) by round platform rubber stopple 8) clog, the device is in stable state, does not produce contracting and moves, works as country rock
Pressure just reaches the round platform rubber stopple 8 that can extrude on cylinder barrel a circle topmost) when, round platform rubber stopple 8) be pressed against in
Casing wall 5) and outer steel wall 6) between cavity, and the volume of cavity and the volume of oil are identicals, cylinder barrel 10) in oil 9) also with
The inflow cavity, while circular steel plunger bottom plate 3), cylinder bottom plate 15) in positioning bracing piece 11) on slidably so as to real
The contracting function of existing device, the device produce that continuous contracting is dynamic, when cylinder barrel 10) in oil after 9) flow through first lap round hole, should
Device stops contracting and moved, by that analogy, until the round platform rubber stopple 8 of the circle of bottom one) be pressed against in cavity, cylinder barrel 10) in
9) oil is all flowed into cavitys, circular steel plunger 16) end and cylinder barrel 10) bottom contacts, shape steel column plug bottom plate 3) and cylinder barrel 10)
Top contact；Device allows pressure amount to exhaust, the part with both ends steel arch-shelf together as Tunnel.Position bracing piece
11) make can the stability of contracting formula device, flexing resistance, torsional property strengthened.
One of ordinary skill in the art will be appreciated that embodiment described here is to aid in reader and understands this reality
