Abstract
The invention discloses a method for assembling segments of shield tunnels with internal water pressures. The method is implemented by the aid of a pair of connector embedded components. The connector embedded components comprise anchor plates and a plurality of connecting anchor bars, and the connecting anchor bars are perpendicularly distributed on the outer sides of the anchor plates. The method includes steps of S1, symmetrically arranging the pair of connector embedded components, connecting one of the connecting anchor bars with one segment and connecting another connecting anchor bar with another segment; S2, connecting the two anchor plates to completely assemble the two corresponding segments. The method has the advantages that the integral strength and rigidity of connectors of the tunnels can be improved, and adverse load impact due to the internal water pressures born on the water delivery, water storage and water drainage tunnels and the like can be resisted.
Description
Technical field
The present invention relates to pipe sheet assembling method, more particularly to a kind of pipe sheet assembling side for the shield tunnel for having interior hydraulic pressure
Method.
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.
The content of the invention
It is an object of the invention to provide a kind of pipe sheet assembling method for the shield tunnel for having interior hydraulic pressure, 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.
In order to realize the above object the present invention is achieved by the following technical solutions：
A kind of pipe sheet assembling method for the shield tunnel for having interior hydraulic pressure, it utilizes a pair of joint built-in fitting, described joint
Built-in fitting is included：Anchor slab, vertical distribution are characterized in several connection dowels in the outside of anchor slab, comprise the following steps：
S1, a pair of joint built-in fitting is symmetrical arranged, and the connection dowel described in one of them is connected with one piece of section of jurisdiction, another institute
The connection dowel stated is connected with another piece of section of jurisdiction；
S2, the anchor slab of connect setting two completes two pieces of assembly of section of jurisdiction.
Two anchor slabs are symmetrical arranged in described step S1.
It is specially in described step S2：Several bolts hole are offered in anchor slab, by bolt passing through bolt hole, makes one
Anchor slab 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.
Also included before described step S1：In the process segment, joint built-in fitting is fixed on section of jurisdiction hand hole location.
The present invention 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 and is brought
Unfavorable load influence.
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.
