Abstract
The invention discloses a kind of design methods of side steel Basalt fiber concrete shield duct piece, and the basic figure of the shield duct piece selected first according to tunnel design carries out the prefabricated of section of jurisdiction ontology, are poured when prefabricated using the concrete that basalt fibre configures；During 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, 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.The invention has the advantages that effect is similar to clean steel section of jurisdiction, but compared with reinforced concrete segment, Basalt fiber concrete section of jurisdiction can not only reduce the steel content of shield duct piece, but also eliminate rubber water-proof, more preferable using welding technique water-stagnating effect, tunnel structure durability is higher.
Description
Technical field
The present invention relates to the designs of tunnel shield duct piece, more particularly, to side steel Basalt fiber concrete shield duct piece
Design method.
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
Hole section uses clean steel section of jurisdiction, but with the appearance of great burying, long range tunnel, the structure stress condition of tunnel becomes increasingly complex,
The brittleness of concrete material also allows its defect to be gradually exposed.Reinforced concrete segment edge in transport and installation process holds
Cracky and generation crack, lead to leakage and corrosion phenomenon, have an adverse effect to the safety and durability of tunnel structure.Cause
This, high security, high usability, high application property, high-environmental, high maintenance and high-durability shield duct piece structure be future
The core strategy of Structural Engineering development and the only way of sustainable development.It is good enough that tunnel lining requires shield duct piece to have
The performances such as toughness, impact resistance, impermeability, corrosion resistance.Currently, common reinforced concrete segment is installed in tunnel lining
When, the linking seam between adjacent section of jurisdiction needs to be arranged rubber water-proof item to meet the sealing of tunnel or only slurry requires, and rubber stops
Water bar is easy aging, greatly affected the safe handling in the later period of tunnel.
Summary of the invention
It is an object of that present invention to provide a kind of design methods of side steel Basalt fiber concrete shield duct piece.
To achieve the above object, the present invention takes following technical proposals:
The design method of steel Basalt fiber concrete shield duct piece in side of the present invention, the shield selected first according to tunnel design
The basic figure in structure section of jurisdiction carries out the prefabricated of section of jurisdiction ontology, is poured when prefabricated using the concrete that basalt fibre configures；Institute
State section of jurisdiction ontology it is prefabricated during, in section of jurisdiction the circumferential interface of ontology and intrados junction it 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 are connected with the circumferential direction of section of jurisdiction ontology
Face 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.
The placing intensity grade of the concrete is C30 ~ C60；The diameter of the basalt fibre is 5 ~ 50 μm, length is
10 ~ 50mm, basalt fibre volume volume are 0.2 ~ 0.3%.
The invention has the advantages that effect is similar to clean steel section of jurisdiction, but compared with reinforced concrete segment, basalt fibre is mixed
Solidifying soil section of jurisdiction can not only reduce the steel content of shield duct piece, but also eliminate rubber water-proof, utilize welding technique water-stagnating effect
More preferably, tunnel structure durability is higher.Meanwhile the design method is easy to operate, the shield duct piece suitable for various types.
Detailed description of the invention
Fig. 1 is the side steel Basalt fiber 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 Basalt fiber concrete shield duct piece in side of the present invention, first basis
The basic figure of the selected shield duct piece of tunnel design carries out the prefabricated of section of jurisdiction ontology, using the mixed of basalt fibre configuration when prefabricated
Solidifying soil is poured；The placing intensity grade of used concrete is C30 ~ C60；The diameter of basalt fibre is 5 ~ 50 μm, grows
Degree is 10 ~ 50mm, and basalt fibre volume volume is 0.2 ~ 0.3%.
During in section of jurisdiction, ontology is prefabricated, the circumferential interface 1 of ontology and the pre-buried thickness in 2 junction of intrados in section of jurisdiction
For 5mm ~ 10mm, the stainless steel angle 3 that One-sided Widths are 5cm ~ 15cm, the shape of stainless steel angle 3 and the circumferential direction of section of jurisdiction ontology
Interface and intrados shape are adapted；Section of jurisdiction ontology after the completion of prefabricated enters tunnel installation, and simultaneously slip casting is steady for end to be installed
After fixed, corner weldering 4 is carried out to the pre-buried stainless steel connecting sewing of adjacent section of jurisdiction ontology joining place, to ensure that section of jurisdiction ontology
Between sealed connection.
