Description
Technical field
The utility model belongs to a kind of tunnel-liner end template structure, and in particular to a kind of tunnel with guarded drainage function
Road lining cutting end template structure.
Background technology
To ensure the safety during tunnel operation, generally require incorporation engineering geology and hydrogeologic condition sets perfect
Tunnel waterproof and water drainage system.And conventional engineering experience shows, there is the situation of percolating water in the weakness such as domestic and international construction joint of tunnel
It is of common occurrence, many problems are brought to tunnel operation, and the waterproof and drainage design at construction joint also gradually causes engineering circles
Pay attention to, take many measures.The theory that guarded drainage is formed at current construction joint of tunnel is mainly based on waterproof, takes
Waterproof measure is mainly " splash guard+back-adhering waterstop+middle buried water stop " or " splash guard+middle buried water stop+chance water is swollen
Swollen sealing rod " etc., it is local that the pumping equipments such as ring blind pipe, drain bar are also provided with construction joint.Although these construction joints are prevented
Some effects can be played after pumping equipment completion, and reduces percolating water risk at lining construction seam to a certain extent.But
Because construction working environment is poor in tunnel, the hydrogeologic condition on periphery is again extremely complex so that the construction of construction joint guarded drainage
Quality is not fully up to expectations, be mainly shown as at liner joint that end template is irregular or do not take effectively support and run mould, in bury
Formula waterstop positioning is inaccurate and lining concrete leakiness causes, by pasting type waterstop failure etc., to cause oozing for lining construction seam
Drainage.
The content of the invention
The utility model is proposed to solve the problems, such as prior art, a kind of with guarded drainage work(the purpose is to provide
The tunnel-liner end template structure of energy.
The technical solution of the utility model is：A kind of tunnel-liner end template structure with guarded drainage function, including
The locating pad and the end template at the lining construction seam of secondary lining of Tunnel or waterproof plate surface are arranged at,
The one end of the end template on the inside of tunnel is junction of the edges of two sheets of paper band, and the other end is rhone, and the rhone openend is by positioning
Pad closure forms infiltration flow-guiding channel.
The cross section of the junction of the edges of two sheets of paper band is trapezoidal, and the trapezoidal bottom is near tunnel inner side.
The rhone is half slot.
The end template is by the prefabricated belt structure of ultra high performance cementitious.
The ultra high performance cementitious are a kind of with portland cement as matrix, with alkali-resistant glass fibre, are closed
It is reinforcing material into fiber, ceramic fibre, carbon fiber, aramid fiber, natural plant fibre, mineral fibres one or more of which
Composite.
The locating pad is fitted in preliminary bracing or waterproof plate surface, diameter of the locating pad width more than half slot.
The end template is circumferentially arranged in lining construction seam.
End template side wall, junction of the edges of two sheets of paper band and secondary lining are brought into close contact.
The utility model medial end portions template leans on tunnel using the prefabricated belt structure of ultra-high performance concrete, wherein cross section
Road inner opposite end is trapezoidal junction of the edges of two sheets of paper band, and the other end is the rhone of semicircular in shape, and locating pad is located at rhone openend, pours
Combined closely with secondary lining after the completion of building, seepage resistance demand can be met, and with enough impermeable structure abilities；Can also prevent
The percolating water on water plate or preliminary bracing surface focuses on semicircle rhone after locating pad is filtered, and ejectment is to tunnel drainage
Outside system discharge hole.
The present invention further simplify the construction technology of lining construction seam, improve the globality of construction joint and anti-row
Aqueous energy, reduces construction joint percolating water risk, it is ensured that tunnel operation security.
