Abstract
It the utility model is related to hydroelectric project field, more particularly to a kind of ring seam construction suitable for pipe of concrete sheet built through seam assembling.Adjacent two pieces concrete lining of the present utility model is bolted at girth joint, and a wherein concrete lining is provided with boss at girth joint, another concrete lining sets fluted, and boss is mutually twisted with groove.The utility model is engaged by boss in lining cutting girth joint and groove, in seam crossing bearing load, obtains bigger frictional resistance or opposition, possesses higher structural stability；Seepage paths is added, is advantageous to structure antiseepage；The constraints of single section of jurisdiction is added, improves the precision of pipe sheet assembling.
Description
Technical field
It the utility model is related to hydroelectric project field, more particularly to it is a kind of suitable for pipe of concrete sheet built through seam assembling
Ring seam construction.
Background technology
Complete-section tunnel boring machine (TBM) is excavated using rotating tool, while country rock and driving in broken hole, is formed whole
A kind of new, advanced tunnel construction machinery of individual tunnel cross-section.Main stress knot of the concrete pipe sheet as TBM drivings tunnel
Structure, the assembled quality of section of jurisdiction are most important.The floating and faulting of slab ends of through seam assembling section of jurisdiction are to perplex the technical problem of tunneler construction,
Easily cause Segment cracking, cause waterproof hidden danger.
Utility model content
Technical problem to be solved in the utility model is：There is provided it is a kind of be readily produced, convenient installation, stability it is higher
Suitable for the ring seam construction of pipe of concrete sheet built through seam assembling.
Technical scheme is used by solve above-mentioned technical problem the utility model：Concrete pipe sheet lining cutting girth joint
Structure, adjacent two pieces concrete lining are bolted at girth joint, a wherein concrete lining at girth joint
Block is provided with boss, another concrete lining sets fluted, and boss is mutually twisted with groove.
It is further：Adjacent two pieces concrete lining is provided with sealing rod in the interface of girth joint.
It is further：Sealing rod is covered with whole girth joint interface.
It is further：Boss height is 50mm~100mm, length is the 1/2~2/3 of concrete lining thickness, width
For the 1/2~2/3 of girth joint width；Groove shapes specification is adapted with projection shape specification.
It is further：Angle between boss surrounding side and seam plane is 40 °~50 °；Groove shapes specification with
Projection shape specification is adapted.
The beneficial effects of the utility model are：By the engaged of boss in lining cutting girth joint and groove, in seam
When locating bearing load, bigger frictional resistance or opposition are obtained, possesses higher structural stability；Add seepage paths,
Be advantageous to structure antiseepage；The constraints of single section of jurisdiction is added, improves the precision of pipe sheet assembling.

Fig. 3 is seaming position schematic diagram of the present utility model；
Marked in figure：1- boss, 2- grooves, 3- concrete linings, 4- sealing rods, 5- bolts, 6- girth joints, 7- bolts
Hole.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in FIG. 1 to 3, adjacent two pieces concrete lining 3 of the present utility model passes through bolt 5 at girth joint 6
Connection, at girth joint 6 a wherein concrete lining 3 be provided with boss 1, another concrete lining 3 set it is fluted
2, boss 1 is mutually twisted with groove 2.
To improve barrier performance, adjacent two pieces concrete lining 3 is provided with sealing rod 4 in the interface of girth joint 6；Only
Water bar 4 is preferably arranged to be covered with the whole interface of girth joint 6, between being stayed at the both ends of the thickness direction of concrete lining 3 necessarily
Gap.
The shape specification preferred arrangement of boss 1 is：Boss 1 (mark is in figure) is highly 50mm~100mm, length
It is girth joint width 6 for 1/2~2/3 (being preferably arranged to 1/2) of the thickness of concrete lining 3, width (mark is in figure)
1/2~2/3 (being preferably arranged to 1/2)；Because boss 1 and groove 2 are mutually twisted, the shape specification of groove 2 and the shape specification of boss 1
It is adapted, correspondingly, groove 2 (mark is in figure) depth is 50mm~100mm, 1/2 that length is the thickness of concrete lining 3
~2/3 (being preferably arranged to 1/2), 1/2~2/3 (being preferably arranged to 1/2) that width is the width of girth joint 6.
For convenience of docking, the surrounding side of boss 1 should be obliquely installed, the angle between the surrounding side of boss 1 and seam plane
For 40 °~50 °, 45 ° are preferably arranged to.Because boss 1 and groove 2 are mutually twisted, the shape specification of groove 2 is advised with the shape of boss 1
Lattice are adapted, and correspondingly, the angle between the surrounding side of groove 2 and seam plane is 40 °~50 °, is preferably arranged to 45 °.
When section of jurisdiction is installed, by the section of jurisdiction erector of manipulator's control, section of jurisdiction is rotated into correct angle, by afterloading tube piece
Boss 1 or groove 2 be directed at the groove 2 or boss 1 of first tubulature piece, in place under the thrusting action of hydraulic jack, pipe sheet assembling
With more constraintss, assembled quality is improved.
In the case where pipe-plate lining is by pressure from surrounding rock, the boss 1 and groove 2 of ring seaming position can be by active forces
It is distributed to by the frictional force between contact surface with the form of pressure on be connected two sections of jurisdiction, can be more compared to plane contact
Good transmission load, improve the stability of liner structure.
In the case where section of jurisdiction is by external water pressure, ring seam construction is grown by extending the surface of contact surface between seam
Degree, effectively extends seepage paths, reduces the infiltration gradient and osmotic pressure of seam crossing.
