Enclosing structure 1 in the present embodiment includes the enclosing panel 11 of half-oval shaped, be single layer thin walled steel structure (
Multi-layer compound structure can be used)；The arcuate surface of enclosing panel 11 is upstream face, and support reinforcing bar 12 is arranged at the top of concave surface, together
When can be used as lift support rod；One group is respectively set on the inside and outside wall surface of enclosing panel 11 for being fixedly connected with the card of floating drum
Button 13.
Water sealing structure 2 in the present embodiment is made of card slot 21, bag 22, flexible water stop 23 and pressure pump 24；Such as Fig. 2
Shown, card slot 21 is the bottom for being set to enclosing panel 11 and downwardly open groove body, its cross sectional shape is square in the present embodiment
Shape；Bag 22 is the tubulose that one end is equipped with the sealing of valve one end, along the elongated inner cavity top for being arranged in card slot 21 of card slot 21；It is soft
Property waterstop 23 along the elongated inner cavity lower part for being arranged in card slot 21 of card slot 21, the present embodiment its cross sectional shape be it is up-narrow and down-wide
Inverted trapezoidal；Pressure pump 24 is for being filled with gas or liquid into bag 22.
By one group of floating drum 31(, it is closed tubular or box-like structure to buoyancy adjustment structure 3 in the present embodiment) and row
Supply mains road 32, water inlet/discharge pipe line 33, air inlet pipeline 34, water pump 35 and air pump 36 form.Floating drum 31 can be fast by buckle 13
Fast ground is fixedly connected with enclosing panel 11；In order to enable buoyancy is balanced, the floating drum 31 on the concave surface and upstream face of enclosing panel 11
Preferably it is symmetrical arranged.When in use, 32 one end of main sewer road is connect with water pump 35, and one end is free；Water inlet/discharge pipe line 33 1
End is connect with floating drum 31, is connected in the middle part of one end and main sewer road 32；34 one end of air inlet pipeline is connect with air pump 36, one end and floating
Cylinder 31 connects.
When needing to carry out cofferdam construction operation, the installation in above-mentioned monoblock type cofferdam can be followed the steps below:
Step 1: floating drum 31 is fixed on enclosing panel 11, and the valve end of bag 22 and pressure pump 24 are tightly connected,
Floating drum 31, main sewer road 32, water inlet/discharge pipe line 33, air inlet pipeline 34, water pump 35 and air pump 36 are tightly connected, and empty bag
Capsule 22 and floating drum 31.
Step 2: monoblock type cofferdam is carried near construction point using loop wheel machine or ship, into the water, cable is then used
It is artificial further to draw to exact position.
Step 3: water pump 35 is placed on the inside of the concave surface of enclosing structure 1, start water pump 35, it is past by main sewer road 32
The outside of enclosing structure 1 drains, while so that cofferdam is gradually sunk to 31 water-filling of floating drum by water inlet/discharge pipe line 33, falling within slope
Face.
Step 4: being pressed into air or water to bag 22 by pressure pump 24, make its volume expansion, squeezes out flexible water stop
23, it is adjacent to flexible water stop 23 with slope surface.
Step 5: step 3 and step 4 are repeated, until cofferdam good seal, without obvious percolating water.
Step 6 continues to use water pump 35 and is drained by main sewer road 32 toward the outside of enclosing structure 1, until cofferdam is enclosed
It is clean to keep off region internal water accumulation pump drainage.
After completing the construction operation in cofferdam enclosing region, cofferdam can be removed according to the following steps:
Step 7: opening the valve pressure release of bag 22 in card slot 21 after the completion of operation, so that bag 22 is let out water/gas and bounce back, in channel
Water leak in enclosing structure 1.
Step 8: be pressed into air into floating drum 31 using air pump 36, make water in floating drum 31 by water inlet/discharge pipe line 33 by
It is gradually discharged, cofferdam is gradually floated with floating drum 31, until emerging.
Step 9: removing cofferdam, carrying is left.If nearby there is working face, can virtue of buoyancy manually drag rope will
Monoblock type cofferdam shifts in water；If completed or working face farther out, be hung on automobile using truck-mounted crane, be transported to next working position
It sets.
Monoblock type cofferdam of the invention overcomes previous cofferdam sealing and to form the technologies such as equipment anti-floating after dry ground operation difficult
Topic has very strong operability and applicability, while can shorten in place, the disassembly and assembly time in cofferdam, simplifies operating procedure, saves
It operating time, shortens the construction period, improves all transfer efficients of device.It the composite can be widely applied to similar water channel, dykes and dams have in this way
There is the hydraulic engineering of lining cutting slope surface, has a good application prospect.
