Mouth 4, protection sleeve pipe 5, Grouting Pipe 6, seepage-proofing gasket 7, rubber weather strip 8, through-hole 9, spring 10, gutter 11, rail 12, fastener
13, railway roadbed 14.
Embodiment: the slip casting structure in the floating plate railway roadbed tunnel in the present embodiment, it is ensured that remained to after the completion of the construction of railway roadbed 14
Go on smoothly slip casting operation.
As shown in Figure 1, the slip casting structure includes railway roadbed 14 and tunnel duct piece 3, railway roadbed 14 includes floating plate 1 and floating plate base
Bottom 2.
As shown in Figure 1, 2, wherein rail 12 is fixed on floating plate 1 by fastener 13, and rail 12 is used to guide train
Wheel advances, and bears the pressure of wheel and pressure is transferred to floating plate 1.Fastener 13 is for connecting rail 12 and floating plate 1.Column
Vehicle and rail 12, which are hit, generates vibration, and floating plate 1 bears the pressure for the wheel that the transmitting of rail 12 comes and eliminates in intrinsic frequency
Vibration.
Floating plate 1 is erected in floating plate substrate 2 by spring 10, and pressure is passed to spring 10 by floating plate 1.Spring 10
It bears pressure and pressure is passed into floating plate substrate 2 and the generated vibration of when train of decaying passes through.Floating plate substrate 2 is used
To bear pressure.Floating plate substrate 2 is fixed on the inner wall of tunnel duct piece 3, so that floating plate substrate 2 and tunnel duct piece 3 are linked as one
Body structure, and smooth supporting surface is provided for floating plate 1.
Grouting port 4 is offered on tunnel duct piece 3, and through-hole 9, the size and location of grouting port 4 are offered in floating plate substrate 2
It is corresponding with the size and location of through-hole 9, it is that channel is reserved in the slip casting operation in later period.Protection sleeve pipe 5 is embedded in floating plate 1,
For protection sleeve pipe 5 in being vertically arranged and running through floating plate 1, the position of protection sleeve pipe 5 is corresponding with the position of through-hole 9, makees for slip casting
Industry reserves channel, it is ensured that can still provide for slip casting operation after the completion of the construction of railway roadbed 14.
Grouting Pipe 6 protrudes into protection sleeve pipe 5, protrudes into grouting port 4 after penetrating through-hole 9, after the completion of the construction of railway roadbed 14, leads to
Crossing Grouting Pipe 6 will be in the gap of slurries injection tunnel pipelines 3 and soil layer.Grouting Pipe 6 is connected with grouting port 4, prevents slip casting process
In, the position of Grouting Pipe 6 shifts.There are gaps between protection sleeve pipe 5 and Grouting Pipe 6, it is ensured that floating plate 1 can exist always
It floats up and down under the action of spring 10, reduces vibration.Seepage-proofing gasket is provided in gap between protection sleeve pipe 5 and Grouting Pipe 6
7, since seepage-proofing gasket 7 has deformability, both can ensure that the free floating of floating plate 1, moreover it is possible to avoid due to floating plate 1 from
Protection sleeve pipe 5 is caused to be hit with Grouting Pipe 6 by floating, moreover it is possible to when carrying out slip casting operation, prevent slurries from protection sleeve pipe 5
It is flowed into the gap between floating plate 1 and floating plate substrate 2 in gap between Grouting Pipe 6, further ensures that 1 energy of floating plate
Realize free floating.
As shown in Figure 1, being equipped with the rubber weather strip 8 as sealing element, rubber seal between floating plate 1 and tunnel duct piece 3
Item 8 is adverse effect of the entrance to 1 performance of floating plate in order to avoid usually rubbish and dust.Floating plate substrate 2 is equipped with row
Ditch 11 further ensures that existing without ponding in railway roadbed 14 and tunnel duct piece 3 for the water in floating plate substrate 2 to be concentrated discharge
As.
Floating plate 1 and floating plate substrate 2 are cast-in-place structural, convenient for determining the position of protection sleeve pipe 5 with through-hole 9.
Protection sleeve pipe 5 can be fixed with the reinforcement welding in floating plate 1, realize the precise positioning of protection sleeve pipe 5.
The implementation steps of the present embodiment:
