Description
Technical field
The utility model is related to shield tunnel engineerings, more particularly to shield segment assembling construction and connectivity kit device.
Background technology
Generally use has the bolt connection of certain rigidity more common at present between shield tunnel prefabricated pipe section lining cutting
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, especially to tunnel segment structure
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
It is so relatively small to the weakening of tunnel segment structure, but pre-buried threaded sleeve is needed, durability, yields and assembly convenience are difficult to simultaneous
It cares for, is especially not suitable for when section of jurisdiction wall thickness is smaller；Curved bolt preferably combines the advantages of straight bolt and oblique bolt, durability,
Stress system, structure is weakened, assembly complexity etc. it is more balanced, 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, curved bolt hand hole is still larger to the weakening of structure,
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 qualities such as degree, leak problem is more prominent, to solve this problem, has done different type in the industry
Trial, research and design gone out miscellaneous positioning device or structure construction.Positioning device used by domestic at present connects
The rebate in seam face constructs, and exists and requires height to section of jurisdiction template, needs to repeat trepanning to tunnel segment structure except bolt hole, to pipe
To promoting tunnel cyclization mass effect unobvious while chip architecture weakens big, pipe sheet assembling difficulty is big, and is easy to section of jurisdiction
Structure causes the problems such as secondary dominant or recessive damage.
To solve the above problems, study and propose that a kind of durability is reliable, assembly is convenient, it is smaller to weaken to tunnel segment structure,
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.
Utility model content
