Above-mentioned operation adopts artificial construction not only time-consuming but also there is potential safety hazard, if geological conditions is poor residing for station, then very easily occurs that in reinforcing bar cutting process, outside sand pours in station, and causes larger security incident.
Utility model content
For solving the problem, the utility model provides a kind of reinforcement cage structure of station difficulty of coming in and going out for reducing shield structure.
The utility model solves the technical scheme that its technical problem adopts:
A kind of reinforcement cage structure of station difficulty of coming in and going out for reducing shield structure, comprise the vertical glass fiber-reinforced polymer being arranged at tunnel shielding portal construction location perpendicular to shield-tunneling construction direction and the vertical reinforcing bar be arranged at outside tunnel shielding portal construction location, the termination of vertical reinforcing bar is fixed on the two ends of vertical glass fiber-reinforced polymer.
Be further used as the improvement of technical solutions of the utility model, be positioned at tunnel shielding portal construction location and be provided with some and each vertical glass fiber-reinforced polymer all by reinforcing glass fiber-reinforced polymer that fixed point is connected.
Be further used as the improvement of technical solutions of the utility model, each glass fiber-reinforced polymer of reinforcing is arranged perpendicular to vertical glass fiber-reinforced polymer.
Be further used as the improvement of technical solutions of the utility model, be positioned at and be provided with some and each vertical reinforcing bar outside tunnel shielding portal construction location all by reinforced steel that fixed point is connected.
Be further used as the improvement of technical solutions of the utility model, each reinforced steel is all perpendicular to vertical steel-bar arrangement.
Be further used as the improvement of technical solutions of the utility model, be connected by U-bolt between vertical glass fiber-reinforced polymer with vertical reinforcing bar, the both sides of U-bolt are for establishing threaded threaded rod, be provided with the pressing plate be pressed on vertical glass fiber-reinforced polymer and vertical reinforcing bar through both sides threaded rod, nut locking is passed through at the two ends of U-bolt.
Be further used as the improvement of technical solutions of the utility model, the junction being positioned at vertical glass fiber-reinforced polymer and vertical reinforcing bar to being provided with at least two U-bolts less.
The beneficial effects of the utility model: this comes in and goes out reinforcement cage structure of station difficulty in shield-tunneling construction position by the making having arranged reinforcing cage of vertical glass fiber-reinforced polymer for reducing shield structure, reinforcing cage is made not have in shield-tunneling construction position the bar construction that strength and stiffness are all larger, safety during this reinforcement cage structure can ensure to lift, simultaneously, carry out shield structure arrive at a station and process leaving from station in, easily can cut off glass fiber-reinforced polymer, and work progress can be avoided to affect the stressed of other positions of diaphragm wall, this structure is safing while, reduce the difficulty of construction at shield structure discrepancy station.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model embodiment overall structure schematic diagram;
