Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to figs. 1 to Fig. 5, the duct pieces of shield tunnel filleting anti-drop device of the utility model includes: runner component 5, in advance
It is embedded to be placed in the section of jurisdiction 1 of 3 two sides of filleting, there is the T-slot 5a extended along its length, the open end of T-slot 5a be located at
On concordant 5 outer surface of runner component of 1 inner surface of section of jurisdiction；Bolt 7,5 longitudinal gap of component is arranged along the chute, and head is located at T
In type groove 5a and by its vertical constraint, the protruding T-slot 5a of 7 tail portion spiro rod section of bolt covers loading nut 8 and pressing plate 6 thereon；Arc
Shape rubber strip 4, across filleting 3, both lateral sides are compressed by bolt 7, nut 8, pressing plate 6 and cushion block 9 is close to table in section of jurisdiction 1
Face.
Referring to Fig. 5, the expansion entered for 7 head of bolt is set on the runner component 5 along T-slot 5a extending direction interval
Macropore 5b.
There are two types of structure types for runner component 5, and when the filleting 3 for longitudinal spliced seam, runner component 5 is embedded in section of jurisdiction in advance
The inside of 1 longitudinal spliced seam, axis are straight line.When the filleting 3 for circumferential splicing seams, runner component 5 is embedded in section of jurisdiction 1 in advance
The inside of circumferential splicing seams, axis are the radius circular arc consistent with 1 inner surface of section of jurisdiction.
Referring to Fig. 6, the middle part in 4 cross section of arc rubber strip is segmental arc 4a, and two sides have an edge of a wing 4b, outside the 4b of the edge of a wing
Edge raises upward, and groove 4c is formed on the 4b of the edge of a wing.Referring to Fig. 2, the cushion block includes outside cushion block 9, inside cushion block 10, outside
Side cushion block 9 is set between 6 bottom surface of 1 inner surface of section of jurisdiction and pressing plate, and inside cushion block 10 is set to the bottom surface groove 4c and 6 bottom surface of pressing plate
Between.Referring to Fig. 7, the cushion block 9 has a through-hole 9a passed through for bolt 7, and in step-like, inside is press boss for cross section
9c is pressed between boss 9c and through-hole 9a and is raised upward the limiting slot 9b at position to accommodate edge of a wing 4b outer edge.
Referring to Fig. 3 and Fig. 2, when Prefabrication section of jurisdiction 1, runner component 5 is installed in segment die by design position, then
Casting concrete is simultaneously conserved to design strength.It is assembled again after the outside installation elastic sealing gasket 2 of section of jurisdiction 1 after demoulding, it is steady to tunnel
Filleting 3 is performed after fixed.Then arc rubber strip 4 is bent along 11 shape of segment joint, while by bolt 7 from expanded hole 5b
It is put into T-slot 5a, and slides into installation site along T-slot 5a.By 6 sets of loading bolts 7 of pressing plate, the outside arranged below of pressing plate 6
Nut 8 is installed to 7 top of bolt and is tightened by cushion block 9.During tightening bolt 7, the position for adjusting cushion block 9 is paid attention to,
So that the press boss 9c of cushion block 9 contacted always with arc rubber strip 4 it is closely connected.
After tunnel operation, if need to check filleting 3, or discovery arc rubber strip 4 has breakage or reaches design use
When the service life, nut 8 and arc rubber strip 4 can be removed, filleting 3 is checked, arc rubber strip 4 repeats the above process after replacing
Carry out installation fixation.
The utility model, which can be realized, is fully sealed longitudinal seam, circumferential seam, and caulking material is effectively avoided to fall off pair
The influence of tunnel operation, it is ensured that train operating safety.Arc rubber strip 4 adapts to vehicle vibration, tunnel longitudinal direction differential settlement
Deformation, can easily carry out dismounting and change after reaching design service life.
