Description
Technical field
The present invention relates to a kind of lining-up construction joint anticracking bridging arrangement and lining-up construction joint lapping construction methods, belong to railway
Tunnel especially Railway Tunnel construction field.
Background technique
In today that national economic development flourishes, high-speed railway has become the important pushing hands promoted economic development,
High-speed railway traffic also has become the important mode of transportation of national trip.Essential group as high-speed railway of Tunnel Engineering
At part, occurs many lining cutting chip off-falling phenomenons in recent years, high risk is brought to the safe operation of high-speed railway.
Currently, Tunnel Second Lining, which is all made of hydraulic lining trolley, pours completion, there is following operating condition in the construction process:
1, it is provided at the vertical, horizontal construction joint between secondary lining, between secondary lining and inverted arch parapet circumferential and vertical
The buried rubber fastening band in, according to lining cutting inside edge 200mm, after being centrally located, embedment front and back each 150mm of lining cutting paragraph, in
Buried rubber fastening band cuts the lining cutting at construction joint, weakens to lining cutting globality at construction joint.
2, after the completion of upper group of secondary lining concreting, lining trolley demoulding is just completed after about 18~20h, through live strong
Degree verifying, lining concrete intensity about 5~7Mpa when demoulding, concrete strength be not high.
3, after the lining of the following group two trolley is in place, rigid overlap joint, the lap of splice about 100mm, to prevent from applying are taken with upper group of lining cutting
Spillage in casting process at work seam often takes the pressure for increasing hydraulic cylinder, makes lining trolley upper group of lining cutting closely connected as far as possible,
In the case where upper group of strength of lining be not high, constantly pressurization will cause group concrete at construction joint and be crushed, and form crescent
Crack after coming into operation, under the effect of the power brought by train high-speed cruising Repeated Compression air, is cut by crescent crack
Concrete there can possibly be formed chip off-falling, jeopardize traffic safety.
Summary of the invention
It is an object of the invention to: a kind of lining-up construction joint anticracking bridging arrangement and construction method are provided, it is existing to solve
Lining-up construction joint in tunnel overlaps firmly easily leads to generation crack at construction joint, and traffic safety, trolley are seriously threatened after coming into operation
Upper end master module overlaps firmly with casting concrete, lap-joint's leakiness, is also easy to produce spillage, and hard overlap joint will cause trolley upper end
The problems such as master module deforms, and lap-joint is caused to generate faulting of slab ends.
To solve the above problems, such a lining-up construction joint anticracking bridging arrangement of proposed adoption, including lining-up trolley main mould
Plate, the tail portion of lining-up trolley master module are fixed with supporting table, the upper surface of supporting table and the upper surface phase of lining-up trolley master module
In parallel, and the upper surface of supporting table is lower than the upper surface of lining-up trolley master module, is equipped with rubber strip on the upper surface of supporting table,
And the thickness of rubber strip is greater than the difference in height between supporting table and lining-up trolley master module upper surface.
In aforementioned lining-up trolley, the width of the rubber strip is 100-150mm, with a thickness of 40-60mm；
In aforementioned lining-up trolley, the upper surface of supporting table is set in the horizontal direction with the upper surface of lining-up trolley master module
It sets, and there are the difference in height of 20mm between the upper surface of supporting table and the upper surface of lining-up trolley master module, the rubber strip is
With a thickness of the rectangular rubber item of 40mm, the compressible amount of rubber strip is at least the 50% of rubber strip thickness；
In aforementioned lining-up trolley, the supporting table is that the design radian circumferential direction along lining-up trolley master module tail portion welds installation
Angle steel or channel steel, one end of supporting table is fixedly welded on the tail portion of lining-up trolley master module, is provided on the downside of supporting table tiltedly
Support, one end of diagonal brace are fixedly welded on the other end of the supporting table, and the other end of diagonal brace is also fixedly welded on lining-up trolley master
The tail portion of template；
The present invention also provides a kind of lining-up construction joint anticracking lapping construction methods, and the specific method is as follows:
When tunnel lining-up is constructed, mobile lining-up trolley makes lining-up trolley master module be moved to the underface of the following group lining-up, rubber
Adhesive tape is located at the underface of upper group of lining-up, slowly jacks lining-up trolley hydraulic cylinder, rubber strip and lining-up trolley master module are gradually
Rising, rubber strip is first in contact with upper group of lining-up, then continues to jack, until lining-up trolley master module rises to design position,
At this point, rubber strip is compressed, and closely overlaps with the lower end of upper group of lining-up, that is, realizes and handled with the soft overlap joint of upper group of lining-up, institute
Stating group lining-up is the upper group of secondary lining-up concrete poured, and the following group lining-up is the secondary lining-up coagulation of the following group to be poured
Soil.
In the above method, when tunnel lining-up is constructed, lining-up trolley is moved first, so that between upper group of lining-up and the following group lining-up
The side flush of construction joint and lining-up trolley master module；
Preferably, two side lower part of trolley and the overlap joint of inverted arch parapet are also constructed according to the method described above.
Compared with prior art, advantage of the present invention is as follows:
1, it is handled using soft overlap joint, lining trolley is effectively avoided effectively to evade platform with the direct overlap joint of casting concrete
Vehicle Leading Edge Deformation avoids that faulting of slab ends occurs, meanwhile, it can also be effectively prevent the generation in crescent crack, deposited when eliminating high-speed rail operation
Security risk, guarantee high-speed rail operation security；
2, it after compressible rubber strip is compressed, is closely overlapped with the upper group of concrete poured, construction can be effectively controlled
Seam is in spillage in casting process, it is ensured that construction joint does not occur honeycomb or chip off-falling, guarantees closely knit at construction joint；
3, compressible rubber strip is reusable, low in cost.
