Description
Technical field
The present invention relates to shield tunnel engineering, more particularly to shield segment assembling construction and connectivity kit device.
Background technology
The bolt connection that generally use has certain rigidity between shield tunnel prefabricated pipe section lining cutting is more commonly used at present
Have straight bolt, oblique bolt and several forms of curved bolt.
It is straight to be bolted that form is simple, and stress system is clear, but its assembly space is more demanding, to tunnel segment structure especially
The weakening of reinforced concrete segment structure is larger, whether difficult by the way of big hand hole or by the way of preset stud
It is larger to overcome the shortcomings of to weaken structure partial；Oblique bolt forms certain angle with segment joint, and stress system is unintelligible, though
Weakening so to tunnel segment structure is relatively small, but needs pre-buried threaded sleeve, its durability, yields and assembling convenience are difficult to simultaneous
Care for, do not applied to when section of jurisdiction wall thickness is smaller especially；Curved bolt preferably combines the advantages of straight bolt and oblique bolt, durability,
Stress system, weaken structure, assemble complexity etc. more equilibrium, but with the change of China's shield tunnel construction demand
Change the development with Shield-type machinery technology, in major diameter, big piecemeal section of jurisdiction, weakening of the curved bolt hand hole to structure is still larger,
And large area is distributed in the bolt hand hole of section of jurisdiction intrados and makes troubles to the design and use of vacuum cup.
Meanwhile as the experience of China's shield tunnel engineering construction for many years and lesson are summarized, shield duct piece faulting of slab ends, Cheng Yuan
Negative effect caused by the assembling quality problems such as degree, leak is more prominent, to solve this problem, has done different type in the industry
Trial, research and design gone out miscellaneous positioner or structure construction.Positioner or connect used by domestic at present
The rebate construction in seam face, exists and section of jurisdiction template is required high, it is necessary to perforate be repeated to tunnel segment structure outside bolt hole, to pipe
To lifting tunnel cyclization mass effect unobvious while chip architecture weakens big, pipe sheet assembling difficulty is big, and easily to section of jurisdiction
Structure causes the problems such as secondary dominant or recessive infringement.
To solve the above problems, study and propose that a kind of durability is reliable, assembling is convenient, it is smaller that tunnel segment structure is weakened,
Ensure to improve the section of jurisdiction connection of hoisting safety while stress system is clear, tunnel Forming Quality is excellent again and position to solve
Scheme is to adapt to China's shield method state-of-the-art and beneficial to its.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of shield segment assembling construction, to effectively reduce section of jurisdiction connection
The weakening effect that demand brings pipe of concrete chip architecture, increase assembling convenience and lifting operation security, and can be good
Ensure tunnel molding effect.
Technical solution is as follows used by the present invention solves above technical problem：
The shield segment assembling construction of the present invention, including positioned at the section of jurisdiction one of seam both sides, section of jurisdiction two, it is characterized in that：Institute
State section of jurisdiction one, be correspondingly arranged the location notch hole to be extended internally by seam end face on section of jurisdiction two, in setting hand hole, hand in adjacent inner wall
Straight line duct towards location notch hole rear portion is set in hole.
Another technical problem to be solved by this invention is to provide a kind of tenon formula for above-mentioned shield segment assembling construction
Be located by connecting external member, effectively to strengthen shield duct piece connector durability and reliability, improves construction efficiency.
It is as follows that the present invention solves the technical solution that the technical problem is taken：
The tenon formula that the present invention is used for shield segment assembling construction is located by connecting external member, it is characterized in that it includes：Tenon formula positions
Connector, insertion section of jurisdiction one, in two corresponding location notch hole of section of jurisdiction, both sides rear portion has its axis and straight line duct axis phase one
The sleeve of cause；Straight line connector, has straight-bar and a clamp nut, straight-bar be inserted into by straight line duct and with homonymy sleeve connection, end
The clamp nut at end is acted on hand hole bottom surface.
The tenon formula positioning link is made of connecting rod, sleeve and flexible body, and sleeve is fixedly connected on the longitudinal direction two of connecting rod
End, sleeve, connection rod set zoarium are embedded in flexible body, and sleeve arrival end is exposed on flexible body.
The invention has the advantages that stress system is clear, durability is reliable, assembling facility；By tenon formula positioning link
Positioning-shear structure body is cooperatively formed with straight line connector so that the Forming Quality in tunnel is more guaranteed, further strengthens
The waterproof quality in tunnel；Whole linked system is without pre-buried primary structure member, and the durability of its integrated connection is easily in flexible body
Protection under more preferably ensured；Straight line connector is easy for installation, and substantially reduces tunnel segment structure inner surface perforate, thus may be used
The adsorbable area of vacuum cup is greatly increased, the security of lifting operation can be effectively improved；For single positioner,
Positioner and connector are formed one by the present invention, are more easy to judge the installation situation of positioner at the scene when operating, and are ensured
Positioner is installed in place, and jerry possibility is avoided from source；Also, the more oblique spiral shell of calculation of this connectivity kit
Bolt is more directly perceived and is easy to judge, is easy to promote and apply in the design.
