Description
Technical field
The present invention relates to shield tunnel, more particularly to a kind of large diameter shield tunnel concrete pipe sheet connecting structure.
Background technology
China's shield tunnel is in High Speed Construction period, and shield method construction is generally referred under the protection of shield machine shield shell
The assembled so as to form tunnel permanent support system of precast block section of jurisdiction is carried out, it is generally certain using having between section of jurisdiction and section of jurisdiction
The bolt connection of rigidity.The way more commonly used at present mainly has straight bolt, oblique bolt and several forms of curved bolt.
Straight bolt connection form is simple, and stress system is clear, but because it assembles principle limitation, tunnel segment structure is especially mixed
The weakening of solidifying soil tunnel segment structure is larger, is whether difficult to by the way of big hand hole or by the way of preset stud
Quality is high takes into account for small on structure influence of assembling；Oblique bolt and seam formation certain angle, stress system are unintelligible, although because
It assembles principle, and the weakening to tunnel segment structure is relatively small, but needs pre-buried thread bush, and its durability and assembling convenience are difficult to simultaneous
Turn round and look at, and do not applied to when section of jurisdiction wall thickness is smaller；Curved bolt preferably combines the advantage of straight bolt and oblique bolt, durability, by
Power system, structure is weakened, it is more balanced in terms of assembling complexity, but with the change of China's shield tunnel construction demand
With the development of Shield-type machinery technology, in major diameter, big piecemeal section of jurisdiction, weakening of the curved bolt to structure is still larger, and big face
The bolt hand hole that integration is distributed in section of jurisdiction intrados is made troubles to the design and use of vacuum cup.
To solve the above problems, study and propose it is a kind of both can guarantee that in large diameter shield tunnel concrete pipe sheet it is durable
Property reliable, assembling is convenient, it is small that structure is weakened, can try one's best again and reduce part hand hole, more spaces are provided for vacuum cup,
The section of jurisdiction connection solution for ensureing to improve hoisting safety while stress system is clear again is to adapt to China's shield law technology
Current situation is simultaneously beneficial to its.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of large diameter shield tunnel concrete pipe sheet connecting structure, with
Weakening of the connecting structure to pipe of concrete chip architecture is effectively reduced, and durability is reliable, assembling facility, increase lifting operation peace
Quan Xing.
The technical solution adopted for the present invention to solve the technical problems is as follows：
Large diameter shield tunnel concrete pipe sheet connecting structure of the present invention, including the first pipe of concrete positioned at seam both sides
Piece and the second concrete pipe sheet, and the connecting elements being integrated is connected, it is characterized in that：The first concrete pipe sheet tool
There are the first hand hole, the first straight hole and the second straight hole, the outer end of the first straight hole connects with the first hand hole, it is the first straight hole, second straight
The axis in hole is staggered, and the outer end of the second straight hole and the seam side wall of the first concrete pipe sheet connect；Second pipe of concrete
Piece has the second hand hole and arc-shaped hole, and one end of arc-shaped hole connects with the second hand hole, the other end and the second pipe of concrete
The seam side wall of piece connects；The straight hole of seam both sides second, arc-shaped hole port it is corresponding；Second straight hole,
The head rod with straight section and circular arc section is penetrated in arc-shaped hole, the second connecting rod penetrates the first straight hole by the first hand hole
Interior, its rear portion is through the connecting hole on head rod and is attached thereto；The head rod front portion has thread segment, nut
With floor clip component in the second hand hole be arranged on the thread segment on.
The beneficial effects of the invention are as follows stress system is clear, and durability is reliable, assembling facility；With section of jurisdiction diameter and wall
Thick increase, it is only necessary to adjust the hand hole size at head rod nut, it is smaller on hand hole influence at the second connecting rod, in reality
In, the second connecting rod side can be arranged on the piecemeal of intrados limited area (such as small block that binds), thus can made true
The adsorbable area of suction disk is greatly increased, and can effectively improve the security of lifting operation；Whole linked system is without pre-buried stress structure
Part, and a full set of connectivity kit later stage can also safeguard replacings, its durability is easy to be ensured using routine coating measure etc.；Even
The more oblique bolt of calculation of joint kit is more directly perceived and is easy to judge, it is easy to popularization and application in the design.

Embodiment
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 7 is the skiagraph of existing shield tunnel concrete pipe sheet connecting structure, in the first concrete pipe sheet 10
Hand hole 72, the inner and the insertion of hand hole 72 of straight hole 73, outer end and the seam A side walls of the first concrete pipe sheet 10 are set in cambered surface
Connect.Seam A opposite side, along the axis of straight hole 73 in setting service sleeve 71 in the second concrete pipe sheet 20.Tilting company
Connecting bolt 70 passes through straight hole 73 by hand hole 72, and its rear portion is connected with the spiral of service sleeve 71.This following three aspect of connecting structure
Deficiency：One is due to the demoulding and the reason for assembly difficulty, the generally plastic material of service sleeve 71, its durability especially with
The engagement capability of the tilting screw thread of connecting bolt 70 has aging to loosen after permanent use causes the risk of Joint failure；Two be to set
Tilting connecting bolt 70 at tunnel vault has the risk dropped, influence train peace after loosening is engaged with service sleeve 71
Entirely；Three be due to the limitation for assembling principle, and the required precision to service sleeve 71 is higher, and the service sleeve 71 has certain give up
Rate is abandoned, and its impaired or destruction situation is difficult to check have an impact the risk of local pipe sheet assembling quality in advance.
