Below in conjunction with specification drawings and specific embodiments, this utility model is illustrated.
Detailed description of the invention
In conjunction with Fig. 1-2, the tunnel-liner of fire safe type other than ring type section of the present utility model, from tunnel-liner
Cross section sees that its structure includes four tunnel lining structure repetitive A being sequentially connected with, and four connect successively
It is circular tunnel-liner that the tunnel lining structure repetitive A connect constitutes periphery；Tunnel lining structure
The inner circumferential circular arc of repetitive A is diminished to central authorities by edge, and the thickness of tunnel lining structure repetitive A
Degree is diminished to central authorities by edge；The tunnel lining of the annular of routine has been broken in tunnel-liner of the present utility model
The mentality of designing built, is fabricated to radian and the most different structure of thickness by the inner circumferential of tunnel-liner, such
Design is from RELIABILITY INDEX, it is ensured that meet the requirement of basic security after fire 30min, and fire resistance is led to
Cross increase concrete thickness to realize rather than sprayed fire proofing coating, save engineering cost in a large number.
Tunnel lining structure repetitive includes the first arc section A1, the second arc section A2 and three-arc
Section A3, the radius of the first arc section A1 is 350cm, and the radius of the second arc section A2 is 100cm, the
The radius of three-arc section A3 is 350cm.The a length of 171cm of the first arc section A1, the second arc section
The a length of 60cm of A2, a length of 171cm of three-arc section A3.Tunnel lining structure repetitive
The edge thickness of A is 53cm, and the central thickness of tunnel lining structure repetitive A is 33cm；Use
Eight hearts circle designs, it is ensured that each cross section reliability of section of jurisdiction is in fairly horizontal, it is to avoid conventional design
Waste of material, ensures the fire protection requirement of tunnel-liner with the minimum material that makes.
Tunnel-liner is respectively prepared first mounting blocks the 1, second mounting blocks 2 and by tunnel-liner when mounted
3rd mounting blocks 3, the lower half circle of tunnel-liner is sequentially connected with by four the first mounting blocks 1 and forms, tunnel
The upper semi-circle of lining cutting is by first mounting blocks the 1, second mounting blocks the 2, the 3rd mounting blocks the 3, second mounting blocks 2
It is sequentially connected with composition with the first mounting blocks 1.Bolt hole 5, bolt hole is connected between adjacent mounting blocks
The end of 5 arranges installing port 4.
Consider the convenient and section of jurisdiction mechanical characteristic of construction, section of jurisdiction is divided into 9 pieces (such as Fig. 2), one piece the
Three mounting blocks 3 are the block that binds, and two piece of second mounting blocks 2 is adjacent block and six piece of first mounting blocks 4
For calibrated bolck.Calibrated bolck specification is consistent, order entanglement when preventing section of jurisdiction from installing.Between section of jurisdiction with bolt even
Connect.Noting during concrete installation, first installing calibrated bolck, next installs adjacent block, finally pacifies
Fill the block that binds, not only ensure that Fast Installation tunnel-liner, moreover it is possible to ensure that the connection between tunnel-liner is tight
Close.
For lining cutting itself, its vault and bottom are affected relatively big when by fire, and spandrel and limit
Wall position is the most relatively small, therefore can consider that different parts arranges different richnesses when rich thickness design
Abundant thickness, saves the most again part concrete material.
According to the parameter designing tunnel-liner that the utility model proposes, use principle of optimality calculated
Fire-resistant RELIABILITY INDEX such as Fig. 4 of tunnel-liner, it is circular for using conventional design, i.e. Internal periphery, lining cutting
Each section thickness is 50cm, fire-resistant RELIABILITY INDEX such as Fig. 3 of its tunnel-liner.
From ratio result in Fig. 3 and Fig. 4, using tunnel-liner of the present utility model, concrete exists
After 30min, each cross section all can guarantee that RELIABILITY INDEX, in the range of basic security, uses conventional design vault
With the arch end and both sides all it cannot be guaranteed that basic security, and each cross section RELIABILITY INDEX differs greatly.This
The concrete section area of the tunnel-liner of utility model is 7.90m2, the coagulation of conventional design tunnel-liner
Soil area of section is 8.64m2, the more conventional design of the design is saved concrete 9.4%, is being saved material
Also ensure that fire-resistant safety requirements simultaneously, be suitable to engineering is promoted the use of.
