Abstract
The invention discloses a kind of design methods of side steel concrete shield duct piece, the basic figure of the shield duct piece selected first according to tunnel design carries out the prefabricated of section of jurisdiction ontology, during the section of jurisdiction ontology is prefabricated, the circumferential interface of ontology and the pre-buried stainless steel angle in intrados junction in section of jurisdiction, the shape of the stainless steel angle and the circumferential interface of section of jurisdiction ontology and intrados shape are adapted；Section of jurisdiction ontology after the completion of prefabricated enters tunnel installation, after end to be installed and slip casting are stablized, corner weldering is carried out to the pre-buried stainless steel connecting sewing of adjacent section of jurisdiction ontology joining place, to ensure that the sealed connection between the ontology of section of jurisdiction.The invention has the advantages that effect is similar to reinforced concrete segment and clean steel section of jurisdiction, but compared with reinforced concrete segment, eliminates rubber water-proof, water-stagnating effect is more preferable, and the tunnel structure durability of lining cutting is higher.Meanwhile the design method is easy to operate, the shield duct piece suitable for various types.
Description
Technical field
The present invention relates to tunnel shield duct pieces, more particularly, to the design method of side steel concrete shield duct piece.
Background technique
Using the tunnel of shield formula tunneler construction, the general carry out lining cutting for using prefabricated reinforced concrete section of jurisdiction is special
Clean steel section of jurisdiction can also be used in hole section.With the appearance of great burying, long range tunnel, the structure stress condition of tunnel is more and more multiple
It is miscellaneous, therefore, high security, high usability, high application property, high-environmental, high maintenance and high-durability shield duct piece structure
It is core strategy and the only way of sustainable development of the following Structural Engineering development.Currently, shield duct piece has clean steel section of jurisdiction
And reinforced concrete segment.Clean steel section of jurisdiction is mainly characterized by that intensity is high, ductility is good, light-weight, but overall stiffness is small, corrosion-resistant
Property is poor, cost is higher；When tunnel lining is installed, the linking seam between adjacent section of jurisdiction needs that rubber is arranged reinforced concrete segment
Sealing rod is come the sealing for meeting tunnel or only slurry requirement, and rubber water-proof item is easy aging, greatly affected the later period of tunnel
Safe handling.
Summary of the invention
It is an object of that present invention to provide a kind of design methods of side steel concrete shield duct piece.
To achieve the above object, the present invention takes following technical proposals:
The design method of steel concrete shield duct piece in side of the present invention, the shield duct piece selected first according to tunnel design are basic
Figure carries out the prefabricated of section of jurisdiction ontology, during the section of jurisdiction ontology is prefabricated, the circumferential interface and inner arc of ontology in section of jurisdiction
Face junction is pre-buried with a thickness of 5mm ~ 10mm, the stainless steel angle that One-sided Widths are 5cm ~ 15cm, the shape of the stainless steel angle
The circumferential interface and intrados shape of shape and section of jurisdiction ontology are adapted；Section of jurisdiction ontology after the completion of prefabricated enters tunnel installation,
After end to be installed and slip casting are stablized, corner weldering is carried out to the pre-buried stainless steel connecting sewing of adjacent section of jurisdiction ontology joining place,
To ensure that the sealed connection between the ontology of section of jurisdiction.
The invention has the advantages that effect is similar to reinforced concrete segment and clean steel section of jurisdiction, but with reinforced concrete segment phase
Than eliminating rubber water-proof, water-stagnating effect is more preferable, and the tunnel structure durability of lining cutting is higher.Meanwhile the design method operation letter
It is single, the shield duct piece suitable for various types.
Detailed description of the invention
Fig. 1 is the side steel concrete shield duct piece axonometric drawing implemented according to the method for the present invention.
Fig. 2 is the structural schematic diagram that the adjacent pre-buried stainless steel connecting sewing of section of jurisdiction ontology joining place implements corner weldering.
Specific embodiment
As shown in Figure 1, 2, the design method of steel concrete shield duct piece in side of the present invention, is selected according to tunnel design first
The basic figure of fixed shield duct piece carries out the prefabricated of section of jurisdiction ontology, in the ontology prefabrication process of section of jurisdiction, the circumferential rank of ontology in section of jurisdiction
Junction 1 and 2 junction of intrados are pre-buried with a thickness of 5mm ~ 10mm, the stainless steel angle 3 that One-sided Widths are 5cm ~ 15cm, stainless steel
The shape of angle bar 3 and the circumferential interface of section of jurisdiction ontology and intrados shape are adapted；Section of jurisdiction ontology after the completion of prefabricated enters
After tunnel installation, end to be installed and slip casting are stablized, side is carried out to 3 connecting sewing of pre-buried stainless steel of adjacent section of jurisdiction ontology joining place
Fillet welding 4, to ensure that the sealed connection between the ontology of section of jurisdiction.
