For traffic tunnel, Hydraulic Tunnel, municipal tunnel, mining tunnel.The tunnel that Organisation for Economic Co-operation and Development in 1970 is held
Meeting combines various factors, to tunnel definition is：" specify shape with certain purposes, in any method of subsurface effect
The cavern that the basal area of shape and size build is more than 2." with China's expanding economy and infrastructure construction scale expansion
Greatly, Tunnel Engineering has become the important engineering in the mega projects such as highway, railway, municipal administration；And due to surrounding enviroment, geology bar
Part limits, or in order to better meet growing traffic flow, transportation condition, or the spacious effect for pursuit large space
Really, the tunnel of shallow buried covered excavation big cross section form is increasing, these tunnels construction when, due to the impact of tunnel substrate, its
When support structure is not enough, the service life in tunnel and the equal difficult to reach of support strength require.
Content of the invention
In view of the shortcomings of the prior art, the technical problem to be solved is to provide a kind of support of tunnel knot
Structure, support effect is good, improves the service life in tunnel.
For solving above-mentioned technical problem, the present invention adopts the technical scheme that, a kind of support of tunnel structure, including tunnel,
Concrete ejection basic unit is provided with tunnel inner wall, the inwall of concrete ejection basic unit is provided with silica gel waterproof layer, silica gel is prevented
It is provided with some nylon wires in water layer, nylon wire is provided with some nylon balls；It is equipped with nonwoven on described waterproof layer inner surface
Layer of cloth, nonwoven layer inner surface is provided with inner concrete injection basic unit, is provided with some in inner concrete injection basic unit
Anchor pole, anchor pole passes through the tail end of nonwoven layer, silica gel waterproof layer and concrete ejection basic unit and anchor pole to be arranged at tunnel substrate
In；It is equipped with lining segment layer on described inner concrete injection basic unit inwall, lining segment layer inner surface is provided with decorative layer.
Optimize, above-mentioned support of tunnel structure, in described concrete ejection basic unit, be provided with some stators, stator
One end is connected with pre- pole, and one end of pre- pole is arranged at tunnel Medium Culture.
Optimize, above-mentioned support of tunnel structure, described anchor pole is provided with some agnails.
Optimize, above-mentioned support of tunnel structure, in described inner concrete injection basic unit, be provided with steel pipe support.
It is an advantage of the current invention that the drawbacks of it can overcome prior art, reasonable in design novelty.The design of the application
It is provided with some nylon wires in silica gel waterproof layer, increased the resistance to tension of silica gel waterproof layer, the setting of nylon ball makes nylon
Line and silica gel waterproof layer internal friction, improve the supporting function for silica gel waterproof layer for the nylon wire.Anchor pole can improve silica gel to be prevented
The degree of being connected firmly of water layer, concrete ejection basic unit and tunnel substrate and silica gel waterproof layer, concrete ejection base can be improved
Degree of being connected firmly in layer support, improves support effect and the service life of supporting construction.Lining segment layer forms external support,
Tunnel Landslide is prevented by the squeezing action between lining segment.The effect of stator and pre- pole can improve concrete further
Injection basic unit and the bonding strength of tunnel substrate and the firmness of concrete ejection basic unit, prevent concrete ejection basic unit from sliding
Take off and affect the supporting role of exterior layers.
