Specific implementation mode
River levee cofferdam includes each pedestal and each cofferdam side being fixed on the upside of river levee and riverbed.As shown in Figure 1, steel cofferdam
Lower bottom base and upper bed-plate 3 and cofferdam side plate 7.Fig. 1 only shows the adjustable base assembling structure of steel cofferdam, passes through the assembly
Structure is that can be appreciated that the mounting structure in entire cofferdam.
Specifically, referring to shown in Fig. 1, Fig. 7 and Fig. 8, lower bottom base includes horizontal lower bottom base 1 and tilts lower bottom base 2, and the two is logical
It is hinged to cross shaft 20.Since horizontal lower bottom base 1 and the middle part for tilting lower bottom base 2 are provided with bottom set tankage 13, so
Hinged specific location is happened on the two side of bottom set tankage 13, as shown in figure 8, wearing pin 18 is located at bottom set tankage
On 13 two side.
Fig. 1 can also be seen that upper bed-plate 3 includes horizontal upper bed-plate and tilts upper bed-plate, and the two is fixed as one.Upper bed-plate
3 horizontal upper bed-plate and inclination upper bed-plate is corresponding with the horizontal lower bottom base 1 of lower bottom base and inclination 2 position of lower bottom base respectively.Moreover,
Horizontal upper bed-plate is fixed together by fixed connecting plate 4 and horizontal lower bottom base 1, is tilted upper bed-plate and is passed through movable plugboard
5 are sleeved in the bottom set tankage 13 for tilting lower bottom base 2.Horizontal lower bottom base 1 and the downside for tilting lower bottom base 2 are provided with suction
Attached pedestal 19.Horizontal lower bottom base 1 and the downside for tilting lower bottom base 2 are fixed on riverbed table by corresponding suction base 19 respectively
Face and river levee surface form sealed bottom connection relation.
Together with cofferdam side plate 7 can be sealedly and fixedly connected by means of lower bottom base with the matching relationship of upper bed-plate 3, formation is enclosed
Weir main body.Lower bottom base provides bottom support, and upper bed-plate 3 provides midfoot support, and overall construction intensity is reliable and stable.
Shown in Fig. 4, Fig. 5 and Fig. 6, horizontal lower bottom base 1 and the middle part for tilting lower bottom base 2 are provided with bottom set tankage
13, horizontal upper bed-plate and tilt upper bed-plate in the middle part of be provided with upper socket 16.Cofferdam side plate 7 passes through upper bottom from upper socket 16
After seat 3, its underpart is sleeved on corresponding 13 inside of bottom set tankage, the mutually embedding connection of side male-female of adjacent cofferdam side plate 7.
In cofferdam, the lower section of side plate 7 is provided with grafting location hole 8, while in 4 upside of the fixed connecting plate of horizontal upper bed-plate
Position, and in 5 upper side position of movable plugboard for tilting upper bed-plate side, it is provided with mounting hole 6, and be equipped with and wear pin 18.
It slightly relaxes after wearing pin 18, it can be achieved that cofferdam side plate 7 moves up and down, to keep cofferdam side plate 7 that can also begin with lower bottom base
Sealing is set in together eventually.Each cofferdam side plate 7 can be firmly fixed to 3 inside of upper bed-plate by wearing pin 18.
And positioned at the edge of bottom set tankage 13 and upper socket 16, and it is located at fixed connecting plate 4 and activity
The edge of plugboard 5 is provided with slot gasket 17.Cooperation slot gasket 17 is clamped fixation, intensity to cofferdam side plate 7
High, seal degree height, using effect are good.
It is provided with lifting regulating mechanism between tilting upper bed-plate and tilting lower bottom base 2.The form of lifting regulating mechanism is more
Sample.Such as lifting regulating mechanism as shown in Figures 2 and 3 may be used, it is vertically provided with nut in the end for tilting upper bed-plate
Pipe 9 and Matching installation have screw rod 11, the lower end of screw rod 11 to stretch into the bottom set tankage 13 for tilting lower bottom base 2, screw rod 11 it is upper
End is laterally fixed with horizontal casing 11 and handle.Using the lifting regulating mechanism, can automatically adapt to pacify according to river levee inclined degree
Dress reaches optimal seal installation condition, and realizes fully support connection.No matter how lower bottom base carries out angular adjustment, can
Enough ensure that cofferdam side plate 7 can be sealed with lower bottom base and upper bed-plate 3 to dock.It is adaptable, various river levees can be common to and carried out
Cofferdam construction.
