Abstract
The utility model relates to a dentate lined tunnel duct piece whose block surface is provided with a dent which is in strip shape, and the end face of the dent is in arc shape, wherein a spacer bar is disposed in the dent on the block surface of one end of the duct piece, which has the advantages of ensuring the spacing requirement in construction assembly, and at the same time on one hand simplifying the steel mould processing technique, thereby being good for increasing the working accuracy of the steel mould and the production quality of the duct piece, and on the other hand the block surface in the same flat surface, and the effective force transfer area is big, thereby the stress condition of the structure is enormously improved, which is good for improving the construction looping quality of the duct piece.
Description
Technical field
The utility model relates to tunnel-like, relates to a kind of lining-built tunnel piping sheet with groove concretely.
Background technology
When lining-built tunnel piping sheet carries out assembly unit in the shield structure, if end face each contact surface in section of jurisdiction is a plane contact, " faulting of slab ends " phenomenon takes place easily during assembly unit, influence construction assembly unit, structural stress state, waterproof effect, serious entail dangers to safety for tunnel engineering.Therefore, during the design of section of jurisdiction, often design a concavo-convex tongue-and-groove, carry out spacing shown in Fig. 1-2 during with the help pipe sheet assembling at blocking surface.But this kind design is when having made things convenient for the construction assembly unit, and also brought adverse effect for structure design: (1) need carry out a plurality of machine because the section of jurisdiction blocking surface is provided with concavo-convex tongue-and-groove, and this makes the punching block processing technology complicated; (2) the section of jurisdiction blocking surface is made up of 3 planes, and during pipe sheet assembling, blocking surface contact planarization is relatively poor, needs to concentrate generation local cracked at padded coamings such as contact surface medial and lateral stickup splines to prevent bight stress; (3) after padded coaming is sticked in the outside in the section of jurisdiction, not directly contact of rebate position in the middle of the section of jurisdiction, section of jurisdiction axial compression transmission relies on the cushion pad power transmission fully, effectively contact surface is little, the section of jurisdiction stress is undesirable, and to material property, the thickness requirement of cushion pad, pastes the accuracy requirement height of position; (4) cushion pad is pasted operation manually-operated at the construction field (site), and influence such as weather, human factor is big, and constructing tunnel quality stability is not high.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of lining-built tunnel piping sheet with groove is provided, its blocking surface of this section of jurisdiction is provided with groove, spacing when being used for pipe sheet assembling, and the size of the size of this groove rebate in the prior art has solved the deficiencies in the prior art fully.
The utility model purpose realizes being finished by following technical scheme:
A kind of lining-built tunnel piping sheet with groove is characterized in that the blocking surface of this section of jurisdiction is provided with groove.
Groove is a strip, and the groove end face is circular-arc.The groove that wherein is arranged on the blocking surface of section of jurisdiction one end is fixedly connected with locating bar.The material that locating bar adopts can be elastomeric material or rubber-plastics material or plastic material or wood materials.
The utility model has the advantages that, in the spacing requirement that has guaranteed the construction assembly unit, make the punching block simplified processing technology on the one hand, help improving the punching block machining accuracy, improve the section of jurisdiction quality of production; On the other hand, the section of jurisdiction blocking surface in one plane, effectively the power transmission area is also bigger, has improved structural stress state greatly, helps improving the section of jurisdiction and constructs into ring quality.
Summary of drawings
Accompanying drawing 1 is a prior art plane structure schematic diagram;
Accompanying drawing 2 is that prior art A is to structural representation;
Accompanying drawing 4 is that the utility model A is to structural representation;
Accompanying drawing 5 is a section structure schematic diagram behind the utility model pipe sheet assembling.
Concrete technical scheme
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Shown in Fig. 1-5, label 1-7 represents respectively: groove surface 1, section of jurisdiction 2, tenon face 3, groove 4, locating bar 5, section of jurisdiction 6, groove 7.
Embodiment: a kind of lining-built tunnel piping sheet that present embodiment relates to groove, comprise section of jurisdiction 2, section of jurisdiction 6, be positioned at the groove 4,7 that is respectively arranged with strip on the blocking surface at its two ends.
Present embodiment in the specific implementation, before 2,7 prefabricated backs, section of jurisdiction, assembly unit, paste a locating bar 5 with adhesive (super glue) in the groove 4 on the assembly unit blocking surface of section of jurisdiction 2,7 one sides, its wood property generally can adopt elastomeric material, can certainly adopt rubber-plastics material or plastic material or even the plastic material of wood materials or the like, the requirement that its intensity only need satisfy construction assembly unit location gets final product.Groove 4 sizes get final product with the installation requirement that satisfies locating bar 5, and this size is much smaller than prior art concave groove face 1, tenon face 3 sizes.
The cavity geometry size that constitutes when groove 4 docks with groove 7 during assembly unit between section of jurisdiction 2 and the section of jurisdiction 6 and the shape size coupling of locating bar 5.
Claims (7)
