Abstract
The utility model discloses a kind of shield tunnel piecing devices for there is interior hydraulic pressure, for connecting section of jurisdiction, the device includes a pair of joint built-in fitting, and each joint built-in fitting is included：Anchor slab；Several connection dowels, its vertical distribution is in the outside of anchor slab；One of connection dowel is connected with one piece of section of jurisdiction, and the connection dowel described in another is connected with another piece of section of jurisdiction, the anchor slab of connect setting two so that two pieces of sections of jurisdiction complete assembled.The utility model can improve the bulk strength and rigidity of tunnel joint, resist the unfavorable load influence that the suffered interior hydraulic pressure such as water delivery, water storage, outlet tunnel brings.
Description
Technical field
The utility model is related to shield tunnel piecing devices, more particularly to a kind of shield tunnel joint for there is interior hydraulic pressure
Device.
Background technology
At present, during optimization water source supply and propulsion sponge city, the water delivery of China's shield construction, water storage,
Outlet tunnel is more and more, based on use armored concrete prefabricated pipe section.Traditional shield tunnel joint is with straight bolt or tiltedly
The method that bolt butt joint is directly attached is not particularly suited for the tunnel joint of interior influence of hydraulic pressure.To reduce interior hydraulic pressure to tunnel
The influence of road structure, frequently with double-deck lining cutting, but the construction period is long and high cost.
Utility model content
The purpose of this utility model is to provide a kind of shield tunnel piecing devices for there is interior hydraulic pressure, improves tunnel joint
Bulk strength and rigidity, resisting the unfavorable load that the suffered interior hydraulic pressure such as water delivery, water storage, outlet tunnel brings influences.
In order to realize the above object the utility model is achieved through the following technical solutions：
A kind of shield tunnel piecing devices for there is interior hydraulic pressure, for connecting section of jurisdiction, are characterized in, comprising a pair of joint
Built-in fitting, the joint built-in fitting described in each is included：
Anchor slab；
Several connection dowels, its vertical distribution is in the outside of anchor slab；
Connection dowel described in one of them is connected with one piece of section of jurisdiction, the connection dowel described in another and another piece of section of jurisdiction
It is connected, the anchor slab of connect setting two so that two pieces of sections of jurisdiction complete assembled.
Each anchor slab offers several bolts hole.
Anchor slab described in each pair is symmetrical arranged, and by bolt passing through bolt hole, a pair of anchor slabs is connected.
Described connection dowel is connected by bearing with anchor slab.
The thickness of described anchor slab determines according to its distribution of force.
The utility model compared with prior art, with advantages below：
1st, the bulk strength and rigidity of tunnel joint can be improved, the suffered interior hydraulic pressure such as water delivery, water storage, outlet tunnel is resisted
The unfavorable load for bringing influences.
2nd, it is special based on the shield tunnel stress by interior influence of hydraulic pressure from the angle for improving duct piece connector stress performance
Point, it is proposed that this is this kind of to can be used for the joint pre-embedded device of single shell lining.
3rd, poured using cast iron, quickly and easily carry out reinforced concrete segment connecting between block, so as to obtain height
The assembled shield tunnel ring of quality.

Specific embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is done and is further explained
State.
As shown in Figure 1, 2, a kind of shield tunnel piecing devices for there is interior hydraulic pressure, for connecting section of jurisdiction 1, joint dress
Put comprising a pair of joint built-in fitting 2, the joint built-in fitting 2 described in each is included：Anchor slab 21；Several connection dowels 22, it hangs down
The straight outside for being distributed in anchor slab 21；Connection dowel 22 described in one of them is connected with one piece of section of jurisdiction 1, the connection described in another
Dowel 22 is connected with another piece of section of jurisdiction 1, the anchor slab 21 of connect setting two so that two pieces of sections of jurisdiction 1 complete assembly.
Each anchor slab 21 offers several bolts hole 211, and according to the actual requirements, the utility model uses four bolts
Hole.Anchor slab 21 described in each pair is symmetrical arranged, and passes through bolt hole 211 by four bolts 212, a pair of anchor slabs 21 is connected.
Described connection dowel 22 is connected by bearing 23 with anchor slab 21.The thickness of described anchor slab 21 is true according to its distribution of force
It is fixed.
As shown in figure 3, in the component process segment, joint built-in fitting 2 is anchored near section of jurisdiction hand hole 11.Fig. 4 gives and connects
Position of the head built-in fitting in the cross section of section of jurisdiction 1,2 built-in fittings are used per endless tube piece 1.The ring assembly stage in section of jurisdiction, such as Fig. 5 institutes
Show, bolt can be pierced into by embedded part bolt hole by artificial or equipment and nut is tightened into completion assembly again.
In sum, a kind of shield tunnel piecing devices for there is interior hydraulic pressure of the utility model, can improve tunnel and connect
The bulk strength and rigidity of head, resist the unfavorable load influence that the suffered interior hydraulic pressure such as water delivery, water storage, outlet tunnel brings.
Although content of the present utility model is discussed in detail by above preferred embodiment, but it should be appreciated that on
The description stated is not considered as to limitation of the present utility model.After those skilled in the art have read the above, for
Various modifications and substitutions of the present utility model all will be apparent.Therefore, protection domain of the present utility model should be by appended
Claim limit.
