The junction of rotating shaft is provided with some rotating shaft pressing plates, and described rotating shaft pressing plate is respectively arranged with pressing plate cambered surface, described pressing plate cambered surface with
Semicircle axial trough is arranged on concentric circular, and described rotating shaft pressing plate is fixed on step-down substructure by some bolts respectively；Institute
State and wedge shape dam body is provided with rotating shaft, be equipped with support arm after described wedge shape dam body, described support arm is connected with formed triangle
The hydraulic jack supporting.This utility model semicircle axial trough diameter be slightly larger than shaft diameter, with rotating shaft insert after its lower camber side with
Semicircle axial trough fits like a glove and is advisable.After bolt fixed rotating shaft pressing plate, pressing plate while rotating shaft pressing plate countershaft is spacing
Cambered surface guarantees the flexibility ratio of rotating shaft operation；" P " shape sealing rod increases rotating shaft side seal near water, reduces rotating shaft and semicircle axial trough
Contact surface leak；Contact surface using dam body after the technical scheme of wedge shape dam body and rotating shaft reduces, operation during wedge shape dam body folding
Resistance face reduces, and realizes the more flexible beneficial effect of folding.It is in engineering finishing phase that rotating shaft pressing plate of the present utility model is installed
Implement, such as dismounting dam, then need first to dismantle rotating shaft pressing plate.
Preferably, described rotating shaft two ends are provided with thin spindle nose, and the thin spindle nose joint portion of adjacent shafts is provided with sealing ring.Adopt
After this technical scheme, rotating shaft junction sealing improves, and can be prevented effectively from rotating shaft immersion corrosion it is ensured that rotating shaft operation is clever
Live, extend dam body service life.
Preferably, described rotating shaft is set to cavity, fill concrete in cavity.Its anti-riverbed and hillside tumble stone punching
Hit, be unlikely to deform it is ensured that the motility of dam body folding.
To sum up, this utility model structure is simple, overcomes the drawbacks of existing hydraulic pressure dam sealing is poor, and service life is short, its
Operation is stable, it is strong to retain function.
Brief description

Fig. 2 is the partial structural diagram of semicircle axial trough and rotating shaft pressing plate；
Fig. 3 is the structural representation of sealing ring working condition.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described：
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of earth axis type of this utility model High Strength Hydraulic dam, including step-down substructure 1,
Described step-down substructure 1 is tilting in the changeover portion of side near water semicircle axial trough 1b, if being provided with described semicircle axial trough 1b
Dry rotating shaft 3；Described step-down substructure 1 is provided with " P " shape sealing rod 2, described step-down substructure with the junction of side rotating shaft near water 3
1 is provided with some rotating shaft pressing plates 5 with the junction of land side rotating shaft 3, and described rotating shaft pressing plate 5 is respectively arranged with pressing plate cambered surface 5a,
Described pressing plate cambered surface 5a is arranged on concentric circular with semicircle axial trough 1b, and described rotating shaft pressing plate 5 is respectively by some bolt 5c
It is fixed on step-down substructure 1；Wedge shape dam body 4 is provided with described rotating shaft 3, after described wedge shape dam body 4, is equipped with support arm 6, institute
State the hydraulic jack 7 that support arm 6 is connected with formed gusseted.
Described rotating shaft 3 two ends are provided with thin spindle nose 3a, and the thin spindle nose 3a joint portion of described adjacent shafts 3 is provided with sealing ring
8.
Described rotating shaft 3 is set to cavity, fill concrete in cavity.
As shown in Fig. 2 before rotating shaft pressing plate 5 is fixing, spacing i.e. half of the left end point 1a to right endpoint 1c of semicircle axial trough 1b
Circular axial trough 1b diameter, now facilitates rotating shaft 3 to insert；After rotating shaft pressing plate 5 is fixing, left end point 1a is little to pressing plate upper extreme point 5b spacing
In the diameter inserting rotating shaft 3, realize the spacing of rotating shaft pressing plate 5 countershaft 3.
Rotating shaft 3 of the present utility model is fixed in semicircle axial trough 1b, and the rotating shaft changing conventional hydraulic pressure dam is arranged on base
Seating face, rotating shaft lower camber side and base contact face are little and cause the drawbacks of sealing is poor, structural strength is low；Rotating shaft of the present utility model
3 half are arranged in semicircle axial trough 1b, and after both increase contact surface, sealing and structural strength are obviously improved, and bearing capacity is more
By force.Pressing plate cambered surface 5a is arranged on concentric circular with semicircle axial trough 1b, guarantees the spirit of its axial rotation while countershaft 3 is spacing
Activity.Wedge shape dam body 4 effectively reduces the faying face with rotating shaft 3, and it is more flexible that dam body folding is reduced in operation resistance face.
Before operation, first in rotating shaft 3 fill concrete to strengthen its structural strength.Step-down substructure 1 mistake in side near water
Cross the semicircle axial trough 1b of setting in section, semicircle axial trough 1b becomes tilting state according to gesture；Afterwards, rotating shaft 3 connects wedge shape dam body 4 and incites somebody to action
Rotating shaft 3 is fixed in semicircle axial trough 1b.After wedge shape dam body 4 installs support arm 6 and hydraulic jack 7, adjacent thin spindle nose 3a is tied
Sealing ring 8 is set at conjunction.Aforesaid operations complete, and rotating shaft pressing plate 5 is fixed on step-down substructure by some bolt 5c respectively
1, a usual rotating shaft 3 is correspondingly arranged four rotating shaft pressing plates 5 and ensures its stability；Afterwards, the rotating shaft 3 of side near water and staged base
Seat 1 junction setting " P " shape sealing rod 2 is simultaneously fixed by sealing bolts 2a, can achieve and retain water after completing to install.
When being related to wedge shape dam body 4 dismounting as engineering, staff need to first dismantle the dismounting of rotating shaft pressing plate 5 row remaining structure again
Work.
From this, this utility model structure is simple, and each structural member cooperation is tight, water-impervious excellent performance.In severe ring
The long-life enabling hydraulic pressure check dam under border uses.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have been shown and described above.One's own profession
