45m/s.Flood discharging tunnel intake tower emergency repair gate to the runner periphery between main gate sets steel plate lining shield, flow-passing surface bottom plate bottom
Steel lining size 19m × 15m（It is long × wide）.The bottom concreting of design requirement steel lining is closely knit firm, it is ensured that high-velocity flow excessively stream
The erosion resistance in face, it is ensured that construction quality and operation safety.Higher requirement is proposed to pouring quality.Steel lining bottom area
And be four sides closing space, conventional concrete pours means and is difficult to the requirement that steel lining bottom pours density.
Utility model content
The utility model provides a kind of device for ensureing that steel lining bottom concreting is closely knit, and the device can be solved effectively
Certainly steel lining and concrete surface are also easy to produce the problem of gravity comes to nothing, and prevent steel lining to be deformed in concreting and position
Move, improve concrete pouring quality, it is to avoid vibrating fatigue that high-velocity flow is produced to steel liner structure is destroyed, it is ensured that construction quality and
Operation safety.
In order to solve the above-mentioned technical problem, the utility model proposes following technical scheme：One kind ensures steel lining bottom coagulation
Soil pours closely knit device, and it includes equidistantly being machined with multiple holes of vibrating on steel lining, the steel lining, is fitted with vibrating on hole
Flexible tremie pipe, the flexible tremie pipe and coagulation are provided with the top of multiple blanking funnel devices, the blanking funnel device
Native pumping installations is connected.
The blanking funnel device includes infundibular body, and the bottom of infundibular body is connected with pipe, the pipe and steel lining
Hole of vibrating is engaged carry out blanking.
Vibrating spear is additionally provided with the hole of vibrating, the vibrating spear is connected by power line with supply unit.
The exterior lateral sides of the steel lining are provided with plasma discharge hole, and the plasma discharge hole is with waiting that pouring top storehouse is connected.
The utility model has the advantages that：
The device is through practice test, first, can avoid completely traditional means steel lining is caused to lift and displacement risk.Its
It is secondary, inner air and concrete laitance are replaced using minute-pressure method realized and pour closely knit, and secondary phenomenon of coming to nothing will not be formed, really
The density of concrete one-time-concreting filling is protected, effect is obvious.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is blanking funnel apparatus structure schematic diagram of the present utility model.
In figure：Steel lining 1, hole 2 of vibrating, plasma discharge hole 3, wait to pour top storehouse 4, blanking funnel device 5, infundibular body 6, pipe 7,
Pouring area 8, flexible tremie pipe 9, the concrete pump set 10, vibrating spear 11, power line 12.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
Embodiment 1：
As shown in Figure 1-2, a kind of device for ensureing that steel lining bottom concreting is closely knit, it includes steel lining 1, the steel lining
Multiple holes 2 of vibrating equidistantly are machined with 1, multiple blanking funnel devices 5 are fitted with hole 2 vibrating, the blanking funnel dress
The top for putting 5 is provided with flexible tremie pipe 9, and the flexible tremie pipe 9 is connected with the concrete pump set 10.
Further, the blanking funnel device 5 includes infundibular body 6, and the bottom of infundibular body 6 is connected with pipe 7, the circle
Pipe 7 is engaged carry out blanking with the hole 2 of vibrating on steel lining 1.
Further, vibrating spear 11 is additionally provided with the hole 2 of vibrating, the vibrating spear 11 passes through power line 12 and power supply
Device is connected.
Further, the exterior lateral sides of the steel lining 1 are provided with plasma discharge hole 3, and the plasma discharge hole 3 pours the top phase of storehouse 4 with waiting
Connection.
Embodiment 2：
In order to solve the problem of steel lining bottom self-compacting concrete pours compactness, following methods are taken to be solved：
Utilize the hole 2 of vibrating set on steel lining 1, design specialized blanking funnel device 5, as shown in figure 1, blanking funnel device
5 set height control 1.2m, setting length suitable for reading and width 1.0m × 1.0m, and lower mouth sets diameter 110mm pipes 7 to be vibrated with steel lining
Hole grafting.The size of blanking funnel device 5 determines that lower port diameter can meet self-compacting concrete diffusion requirement by field experiment,
Material head pressure energy, which is met, pours density requirement.
Control principle, as shown in Figure 1：Steel lining bottom pours self-compacting concrete, first certain with conventional pumping means filling
The concrete of volume forms pouring area 8, and pump concrete is poured to be stopped pumping from steel lining bottom 20cm or so, utilizes the device
The reserved hole blanking of vibrating at the top of the steel lining, is gradually extended to untill steel lining bottom is all filled with by blanking order from side.
Using the device in last space filling process, note observing the exhaust at plasma discharge hole 3 and arrange laitance fully, blanking is completed
