Abstract
The present invention relates to immersed tube tunnel, and especially steel drag cable connecting structure for the pipe section joint in immersed tube tunnel. The connection structure includes steel drag cable with extruded ends and end fixing anchor rings on two ends of the cable, and features that the one end of the end fixing anchor ring has positioning eye ring and connecting sleeve jacketing the eye ring. The present invention has the advantage of forming tensile constraint condition between adjacent pipe sections to avoid the drug separation of the pipe section joint and ensure reliable waterproof performance of the joint without generating additional constraint and harmful secondary stress. The present invention has fast construction speed, no need of welding and no negative effect on concrete in the joint.
Description
Technical field
The present invention relates to the immersed tube tunnel class, relate to a kind of steel cable syndeton that is used for the immersed tube tunnel tunnel joint concretely.
Background technology
The joint form of immersed tube tunnel has rigidity and flexible two big classes, and flexible joint allows tunnel joint that an amount of rotation and displacement take place, and when bearing certain pulling force, shearing and moment of flexure, still can guarantee the joint watertightness.Calculate as can be known by concrete analysis the Shanghai City Outer Ring Line Tunnel, as adopt the flexible joint scheme, then the shearing numerical value of bank structure and immersed segment joint only is 44% of rigid joint scheme, and maximal bending moment in the pipeline section and maximum shear are respectively 68%, 97% of the rigid joint scheme that adopts.The main effect one that flexible joint is born is the requirement of satisfying joint waterproofing, the 2nd, allow limited distortion, and in order to reach above-mentioned requirement, flexible joint must have the ability of tension, resistance to compression, shearing resistance and bending resistance, has reliable waterproof measure.The syndeton of the flexible joint between the pipeline section of port, Tokyo deep tunnel as shown in Figure 8, with being Ω shaped steel plate and two adjacent tubular segments end box hat steel plate welding, one of the shortcoming of this structure is to have additional constraint, the additional constraint of shearing resistance and bending resistance promptly can be provided simultaneously in the axial tension constraint that provides design to need, and the inferior internal force that additional constraint produces can cause structure partial stress too high; Another needs a large amount of field Welding, and the localized hyperthermia that welding produces can constitute injury to the concrete of prefabricated tube section; The Ω shaped steel plate need adopt special steel plate to make in addition, and cost is higher, and construction is complicated.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of steel cable syndeton that is used for tunnel joint is provided, the setting of this syndeton by branch sleeve, positioning ring and dependency structure makes steel cable that single tension constraints only is provided and tunnel joint do not caused the functional requirement of other additional constraint.
The object of the invention realizes being finished by following technical scheme:
A kind of steel cable syndeton that is used for tunnel joint, comprise the steel cable cable body, and the fixed end anchor ring that is positioned at the cable body two ends, the cable body two ends are extrusion head, an end that it is characterized in that the fixed end anchor ring is provided with positioning ring, is set with branch sleeve on the positioning ring outer wall.
Adopt between the outer wall of positioning ring and the branch sleeve inwall and be threaded.
Advantage of the present invention is, forms the constraints of tension between adjacent tubular segments, avoid tunnel joint when earthquake takes place owing to tension is opened the waterproof reliability that jeopardizes joint; When forming the tension constraint, tunnel joint is not produced other additional constraints, avoid under the earthquake operating mode, harmful secondary stress being caused at the tunnel joint position; The speed of construction is very fast, need not to adopt welding procedure in the installation process, and the concrete at butt joint position can not produce adverse influence.

Concrete technical scheme
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Shown in Fig. 1-8, label 1-8 represents respectively: P anchor extrusion head (1), fixed end anchor ring (2), steel cable cable body (3), positioning ring (4), branch sleeve (5), Ω shaped steel plate (6), pipeline section end box hat steel plate (7), fixed end anchor ring (8).
Present embodiment mainly comprises P anchor extrusion head (1), fixed end anchor ring (2) (8), steel cable cable body (3), positioning ring (4), branch sleeve (5), Ω shaped steel plate (6), fixed end anchor ring (2) (8) is positioned at cable body (3) two ends, cable body (3) two ends is a P anchor extrusion head (1), positioning ring (4) abuts against an end of fixed end anchor ring (8), on positioning ring (4) outer wall, be set with branch sleeve (5), adopt between the outer wall of positioning ring (4) and branch sleeve (5) inwall to be threaded.
One end face of positioning ring (4) can be made the inclined-plane for the ease of construction and installation.
Usually the external diameter of fixed end anchor ring is less than the internal diameter of branch sleeve.
The present invention in use, during whole syndeton tension, fixed end anchor ring (2) near steel cable cable body (3) outer end is held on the built-in fitting end plate, then be held on the positioning ring (4) near middle fixed end anchor ring (8), positioning ring (4) links to each other with branch sleeve (5) by screw thread, therefore, the pulling force that bears in the cable wire cable body (3) passes to positioning ring (4) by fixed end anchor ring (8), pass to branch sleeve (5) by positioning ring (4) again, finally realize the transmission of two ends pulling force.Owing to be not fixedly coupled between fixed end anchor ring (8) and the positioning ring (4), when the utility model product pressurized, near throwing off fully between middle fixed end anchor ring (8) and the positioning ring (4), therefore the cable body in the syndeton both sides can not transmit pressure because of the branch sleeve (5) of centre, in addition, whole steel cable almost do not have bending rigidity.So just realize steel cable that single tension constraints only is provided and tunnel joint has not been caused the functional requirement of other additional constraint.
Claims (3)
1, a kind of steel cable syndeton that is used for tunnel joint, comprise the steel cable cable body, and the fixed end anchor ring that is positioned at the cable body two ends, the cable body two ends are extrusion head, an end that it is characterized in that the fixed end anchor ring is provided with positioning ring, is set with branch sleeve on the positioning ring outer wall.
2, a kind of steel cable syndeton that is used for tunnel joint according to claim 1 is characterized in that being set with on the described positioning ring outer wall adopting between outer wall that branch sleeve refers to positioning ring and the branch sleeve inwall and is threaded.
3, a kind of steel cable syndeton that is used for tunnel joint according to claim 1 is characterized in that the internal diameter of the external diameter of described fixed end anchor ring less than branch sleeve.
