A kind of immersed tube tunnel section disconnector alternating expression fireproof construction, the thickness of every layer of flame barrier are not less than 10mm.
The technical effects of the invention are that when fire occurs, section disconnector cavity inside temperature is in uneven distribution, middle
Portion temperature is higher, and both sides temperature is relatively low.Before this alternating expression fireproof construction meets the needs of segment joint area fire resistance
Put and have necessarily flexible ability concurrently, effectively eliminate the possibility for causing fire proof construction to be destroyed due to the deformation of segment joint area.
Additionally due to the structure center section is due to having the superposition of both sides fire-proof plates and thickness is thicker, so good heat-insulation effect.In addition this is tied
Structure both sides fire-proof plate overlapping area is big, while the rock wool filled in the preset clearance at expansion joint all further improves the close of structure
Effect is sealed, effectively controls high-temperature flue gas channelling, weakens heat transfer, improves immersed tube tunnel section disconnector in fire process
Safety and stability, economically reduces maintenance cost of the tunnel structure after fire, is in time staff in tunnel
Escape and fire fire-fighting rescue provide condition advantageously.
The invention will be further described below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention；
Wherein, 1 be fire-proof plate, 2 be expansion joint, 3 be expansion bolt, 4 be heat-insulated rock wool, 5 be immersed tube tunnel section disconnector,
6 be OMEGA waterstops.
Embodiment
The present embodiment is a kind of sinking pipe tunnel section disconnector fireproof construction, utilizes fire-proof plate and thick rock wool combination installation
Mode, flameproof protection is carried out to the waterstop of immersed tube tunnel section disconnector.
Referring to Fig. 1, the present embodiment is installed on two bottoms for saving disconnected joint location of immersed tube tunnel made of concrete,
Including the multi-layer fireproofing part being fixed on the main body section of section disconnector both sides and heat-insulated rock wool.Flame barrier passes through expanding screw
Bolt is fixed in section disconnector agent structure.Every layer of flame barrier includes two pieces of fire-proof plates and reserved certain interval is as expansion joint,
The expansion joint of adjacent every two layers of fire-proof plate is respectively at different sidewall bottoms, so that expansion joint forms interlaced knot
Structure, while meet tensioning and the needs shunk on longitudinal direction.Stuffed heat insulated rock wool is to ensure to seal heat-insulated effect inside expansion joint
Fruit.
It should be noted that：Two pieces of fire-proof plates in every layer of flame barrier, one of fire-proof plate is from immersed tube tunnel section disconnecting
The bottom of head wherein side side wall extends to bottom opposite side sidewall bottom, and another piece of fire-proof plate is arranged at opposite side side wall bottom
Portion, that is, the lap of flame barrier and section disconnector are greater than the disconnected cavity width of section.In addition, the heat-insulated rock wool in expansion joint
To retain certain redundancy when mounted.
To ensure flameproof effect, the both sides outer rim of every layer of flame barrier is grown with the overlap joint of immersed tube tunnel section disconnector both sides side wall
Degree is more than 20cm, and the both sides outer rim of every layer of flame barrier of the present embodiment is set with the outer rim of immersed tube tunnel section disconnector both sides side wall
To be concordant.Horizontal distance of the expansion joint apart from the inner edge of residing corresponding immersed tube tunnel section disconnector side wall is not less than 5cm.Together
When, the flame barrier of the superiors is equipped with heat-insulated rock wool at the cavity of immersed tube tunnel section disconnector.
To ensure to leave enough extendable rooms, the width at expansion joint is not preferably less than 2cm.
Mounted fire-proof plate should be able to bear the requirement of positive/negative-pressure circular wave caused by air flow in tunnel.
Connector should not be less than 2 layers per side fire-proof plate, can be required increase fire-proof plate quantity or increase single according to fire resistance
Block is prevented fires plate thickness, and to improve heat insulation, but monolithic fire prevention plate thickness is not lower than 10mm, with ensure basic heat insulation and
Structural strength.
The expansion bolt of fixed fire-proof plate and pressing plate uses M6 diameters.The selection of expansion bolt diameter there are certain requirements, mistake
It is big then obvious stress concentration phenomenon occurs, it is too small needed for expansion bolt quantity it is more, add difficulty of construction.
Implantation depth of the expansion bolt in concrete is too short preferably between 4~5cm, easily falls down, long appearance
Reinforcing bar easily is run into, structure is had an impact.
Expansion bolt need to wear gasket, and when construction answers gasket to be contacted with fire shield surface closely.
Expansion bolt should be able to meet the requirement of corrosion resistance.Since air ambient is dirty in tunnel, it should ensure that and designing
Service life endoadaptation corrosive environment.
Inner layer expansion bolt must use intumescent in countersunk head cross, and require expansion bolt outer surface and fire shield surface
Concordantly.
Should not too it exert a force to expansion bolt during construction, in order to avoid produce stress concentration phenomenon.
Thick rock wool is fixed on fire-proof plate waterstop side by expansion bolt and angle steel, and installation will also retain certain redundancy,
With the needs for meeting tensioning and shrinking.And possess the condition for the requirement for meeting seabed tunnel environment, such as the flammability of material
Energy, thermal conductivity factor, water content, water absorption rate, durability, acid and alkali-resistance etc., and it is nontoxic environmentally safe, meet at high temperature
The related request to material.
