Description
Technical field
The invention belongs to tunnel duct piece technical fields, are hung more particularly to a kind of fire-proof plate equipped with shape memory effect
The duct pieces of shield tunnel of part.
Background technology
Shield duct piece is the main mounting structure of shield-tunneling construction, is the innermost layer barrier in tunnel, carries and resists soil layer pressure
The effect of power, groundwater pressure and some special loads.Shield duct piece is the permanent lining, secondary lining structure of shield tunnel, shield pipe
Tablet quality is directly related to the total quality and safety in tunnel, influences the water resistance and endurance quality in tunnel.
The high-strength water-tight concrete of production generally use of shield duct piece, it is raw to ensure reliable load and water resistance
Production is mainly i.e. plastic after sealing placing concrete using finished product segment die.
The one kind of shield method as boring construction method, due to having：（1）Influence to ambient enviroment is small；（2）Construction not by
The influence of synoptic climate such as strong wind, heavy rain, snow etc.；（3）In entire shield tunneling process, not by the various environment items of morphosequent
The restriction of part, adaptability are good；（4）Mechanization intensity is high, and construction efficiency is high；（5）Automatically controlled using informationization, convenient for into
The advantages that row construction management.In recent years, with the development of urban rail transit in China and the progress of shield technique, increasingly
The traffic tunnels such as more city underground, across rivers sea tunnels are all built using shield technique.
One of most important disaster and the major Safety of social concerns during fire is exactly tunnel operation.Tunnel
Fire once occurs, it will makes quite heavy casualties and huge economic loss, also brings along great social influence；
Meanwhile also can Dui Chen Gun structures cause different degrees of damage, occur so as to cause the bearing capacity of Chen Gun structures and safety
Different degrees of reduction.Dun structure Sui Dao Chen Gun structures be mainly multiple section of jurisdiction components connected by screwed joint it is assembled.The roads Insurance
When fire occurs, mainly section of jurisdiction component is caused greatly to damage, be dropped so as to cause entire tunnel segment structure bearing capacity and safety
It is low.Therefore, how to ensure that the safe and reliable of shield tunnel chip architecture is ground it is necessary to improve and perfect tunnel structure fire-resistance under fire
Study carefully method, keeps security evaluation and repairing and reinforcement after its resisting fire design and fire more scientific and reasonable.
Tunnel concrete structure thermal insulation layer flameproof protection method mainly has sprayed fire proofing coating and laying fire-proof plate.Due to tunnel
The factors such as deformation, the leak of road structure make fireproof coating layer easy to crack and material property reduces, and not only influence flameproof effect,
And influence service life;And laying fire-proof plate scheme is used, and although having adapted to certain deformation requirements, its piece, metal
Partial heat is transmitted to body structure surface by fastener, and surface structure is caused to damage, and construction and subsequent maintenance are inconvenient.
Tunnel recombination fire protection design is a kind of systematic measures for tunnel concrete structure flameproof protection, is hung with special
The flexible way of pendant hanging mental keel is effectively absorbed because of adverse factors such as section of jurisdiction harmomegathus, sedimentation, deformations, make attachment its
On fire proof construction will not be destroyed;It selects simultaneously and has excellent impact strength and anti-folding failing load surface plank, have
Effect absorbs positive and negative pressure shock wave when vehicle high-speed disengaging, meeting.
Therefore, it is necessary to invent a kind of duct pieces of shield tunnel of the fire-proof plate suspender member equipped with shape memory effect, improve
Deformation and recovery capability of the fire-proof plate on tunnel duct piece improve the assembled degree of tunnel duct piece and suspender member.
