Specific embodiment
Below in conjunction with attached drawing, the technical solution of the utility model embodiment is described.
As shown in Figure 1, a kind of for wearing the structure of shutting off in river under shield tunnel, including be arranged on shield tunnel 1 with
The vertically disposed twice in river 2 cutout cofferdam 3, cutout cofferdam 3 are fixedly mounted along boring direction of the shield tunnel 1 under riverbed
On riverbed.
As shown in Fig. 2, cutout cofferdam 3 includes foundation pile 301 and water fender 302.By pile driving barge along design on river 2
The trend in cutout cofferdam 3 squeezes into foundation pile 301 in riverbed, and two lateral edge foundation pile of outer surface, 301 length direction of foundation pile 301 is symmetrically opened
Equipped with fluting 4, the fluting 4 between two neighboring foundation pile 301 is oppositely arranged, and is inserted between two adjacent foundation piles 301 by fluting 4
Be connected to two neighboring 301 distance length of foundation pile match water fender 302, water fender 302 by hang ship hang in it is two adjacent
Between foundation pile 301.
In conjunction with Fig. 2 and Fig. 3, water fender 302 includes overhead gage 3021 and lower baffle plate 3022.By hanging ship first for lower baffle plate
3022 hang between two adjacent foundation piles 301, then lower baffle plate 3022 is squeezed into riverbed along 4 directions of fluting by pile driving barge
In, then overhead gage 3021 is hung between two adjacent foundation piles 301 by hanging ship and is compressed with lower baffle plate 3022.Overhead gage 3021
On be provided with through-hole 8,8 upper flange of through-hole is connected with water service pipe 9.It is provided with valve 10 on water service pipe 9, is installed in overhead gage 3021
When, valve 10 is closed.
As shown in Fig. 2, running through between twice cutout cofferdam 3 has more perpendicular overflow pipes 7 excessively and is provided with more
The strut 11 that both ends are abutted with cutout cofferdam 3.Overflow pipe 7 and water service pipe 9 are crossed by flanged joint, will be divided by crossing overflow pipe 7
Every river 2 be connected to, prevent river water stretch into cutout cofferdam 3 in, influence to construct.Strut 11 is bolted with lower baffle plate 3022,
It is supported on by strut 11 on two pieces of opposite lower baffle plates 3022, provides supporting for cutout cofferdam 3, reinforce the steady of cutout cofferdam 3
Solidity.
As shown in figure 3, the lower section of lower baffle plate 3022 and riverbed junction have been bolted stiffener plate 12, by lower block
Plate 3022 and riverbed junction are provided with stiffener plate 12, and on the one hand the ability of river water impact is resisted in enhancing cutout cofferdam 3, another
Aspect reduces the infiltration of 3022 lower section of lower baffle plate.
As shown in figure 4, the edge of overhead gage 3021 and the edge of lower baffle plate 3022 have only by multiple 6 nail joints of steel nail respectively
Water bar 5, when overhead gage 3021 and lower baffle plate 3022 between adjacent company foundation pile 301 after the installation is completed, it is swollen that sealing rod 5 meets water
It is swollen, so that sealing rod 5 fills up the gap formed between water fender 302 and fluting 4, reduce the leakage of water.
Specific work process: when wearing river 2 under shield tunnel 1, the riverbed to this section of river 2 is needed to reinforce.Base
Stake 301 is beaten in the riverbed above shield tunnel 1 by boring direction of the pile driving barge along shield tunnel 1 under riverbed
Stake squeezes into foundation pile 301 according to the arrangement of the even width in river 2.Again by 9 flanged joint of water service pipe overhead gage 3021 through-hole 8
On, close the valve 10 on water service pipe 9.Then successively by lower baffle plate 3022 and overhead gage 3021 by hang ship hang in two it is adjacent
Foundation pile 301 between in opposite fluting 4, then by pile driving barge the overhead gage 3021 and lower baffle plate 3022 of splicing are hit
It beats, so that baffle protrudes into riverbed, reduces leak.Stopping for nail joint is distinguished on upper and lower 3022 side of baffle in 3021 side of overhead gage
5 water-swellable of water bar.When foundation pile 301 and two sides riverbank, which form gap, to be inconvenient to install baffle, filled up by sandbag.
Stop after the completion of the construction of the periphery of cofferdam 3, drain the river water in cutout cofferdam 3 with water pump, clear up river bed mud and
Sundries, then lifted strut 11 outside cutout cofferdam 3 by hanging ship, it is bolted under 3 both sides of cofferdam that stop
On baffle 3022, supporting is provided for cutout cofferdam 3, improves the stability in cutout cofferdam 3.
Construction personnel enters in cutout cofferdam 3, is bolted reinforcing rib in the lower section of lower baffle plate 3022 and riverbed junction
Plate 12, then lifted overflow pipe 7 by hanging ship, cross water flowing of the overflow pipe 7 by flanged joint on cutout 3 both sides of cofferdam
It is multiple to cross overflow pipe 7 after the installation is completed on pipe 9, valve 10 is opened, the river 2 of separation is connected to.At this point, cutout cofferdam 3
It basically forms, construction personnel, which can enter inside cutout cofferdam 3, carries out bed stabilization construction.
