Embodiment
The present embodiment is only an optimal technical scheme, wherein each involved building block and annexation are not limited
The setting and connection of each building block in a kind of this following embodiment described by the embodiment, the preferred scheme
Relation can carry out arbitrary permutation and combination and form complete technical scheme.
As Figure 1-3, a kind of detection pipe for Tunnel Second Lining vault concrete construction, including body 1 and rubber
Plug 2, one end of body 1 is provided with cross-shaped aperture 3, and rubber stopper 2 is sleeved at cross-shaped aperture 3, the depth of cross-shaped aperture 3
No more than 3cm, the depth of the parcel body 1 of rubber stopper 2 is no more than 1cm, and the bottom thickness of rubber stopper 2 is 1cm, effectively to prevent
The contact wear of the detection pipe and splash guard.Including detachable supporting steel plate 5, the other end of body 1 and detachable support
Steel plate 5 is connected.Including the first fixation steel plate 6 and the second fixation steel plate 7, the both sides of detachable supporting steel plate 5 pass through first
The bolt 9 of bolt 8 and second is connected with the first fixation steel plate 6 and the second fixation steel plate 7 respectively.The bottom of body 1 is provided with valve
Door 4.Rubber stopper 2 can use fluorubber or silicon rubber or nitrile rubber.
As shown in figure 4, illustrating for the existing detection pipe mounting structure for Tunnel Second Lining vault concrete construction
Figure.When being constructed using existing detection pipe 11, two serve as a contrast vault leakiness probability up to 65%.
The utility model is able to ensure that detection pipe can directly withstand splash guard in work progress, because splash guard has one
Fixed slackness, can also overflow directly by splash guard top to first branch face finally by the position for being not more than 2cm apart from first branch face
Slurry, so as to realize Tunnel Second Lining vault concrete compaction, the technique effect do not lost gap, do not stay dead angle.Through construction verification,
It is only 5% using the leakiness probability after the utility model, the two uncompacted quality problems of lining vault concrete is greatly reduced,
Technique effect is obvious.
The secondary lining is the form concrete or armored concrete applied on the inside of tunnel construction supporting in the early stage
Lining cutting, composite lining is collectively constituted with preliminary bracing.The general provision of the secondary lining：Tunnel Second Lining structure coagulation
Soil should closely knit, surfacing be smooth, curvilinear circular is suitable, meets design strength, waterproof and life requirement.Secondary lining coagulation soil application
Cement, fine aggregate, coarse aggregate, mixing and maintenance is tackled before work to be tested with raw material such as water, additive, admixtures, it is every
Technical indicator should echo the relevant regulations of acceptance criteria.According to the concrete condition at scene, it should suitably increase the outer of secondary lining and put
Value（Construction positive error）, in order to avoid invade limit.Tunnel arch backbreak part should use with secondary lining with strength grade concrete once
Pour.The order of Second Lining Construction is that inverted arch is advanced, wall, arch one-piece casting.The position of abutment wall height of foundation（Divergence
Seam）The maximum section of shearing should be avoided, and makees water-proofing treatment by design requirement.Concrete production, which should be used, has automatic gauge dress
The blending station put, mix and stir waggon, concrete pump, plug-in type the machanized line vibrated is combined with adhesion type.It is secondary
The concrete of lining cutting, from the inspection and selection of raw material, the proportioning of concrete and mixing, the control of placing temperature and vibrate, to
The each operation of lining cutting maintenance must be operated on request, prevent the generation of Lining Crack.
The secondary lining applies condition：（1）Secondary lining, which applies general deformed in country rock and preliminary bracing, tends to be steady
Carried out after fixed.（2）In tunnel portal section, Shallow Section, country rock loose crushing section, secondary lining should be applied as early as possible, and answer reinforcing line
Build structure.（3）Carry out preliminary bracing, waterproof layer, ring longitudinal drainage system of operation section of secondary lining etc. and check and accept conjunction
Lattice；Waterproof layer surface dust has been removed totally.（4）Splash guard paving location answers advanced Second Lining Construction.（5）Secondary lining is applied
Tunnel center line, elevation and cross dimensions are checked before work, it is necessary to meet design requirement.（6）Packed layer or shop fixtures on inverted arch, which are adjusted, to be looked for
Flat bed, which has been constructed, to be finished；Underground water reasonable ejectment；Construction joint handles qualified by design requirement；Basic part no-sundries, product
Water.（7）The illumination of secondary lining operating area, power supply, water supply, drainage system can be met in lining cutting normal construction requirement, tunnel
Ventilation condition is good.Inverted arch and construction of bottom plates：（1）The empty slag of Tunnel Base, debris, mud, ponding etc. are cleaned out before construction,
And with high-pressure blast by tunnel bottom blowing wash clean, part of backbreaking is using concrete backfill at the same level.（2）During inverted arch one-piece casting, done to be anti-
Disturb operation and use trestle, to ensure that working space and young concrete structure are without damage.（3）Tunnel bottom is applied in time after excavating
Inverted arch or screed-coat, inverted arch or underplate concrete answer one-piece casting, once-forming, and fill concrete should be in inverted arch concrete final set
After carry out.（4）Inverted arch construction joint and movement joint should make water-proofing treatment.
The fluorubber has heat-resisting quantity, can be used in -30 DEG C -+250 DEG C environment, powerful oxidation corrosion resistance agent, oil resistant, resistance to
Soda acid.It is generally used in high temperature, high vacuum and hyperbaric environment, is suitable for oils environment.The silicon rubber has prominent resistance to height
Cryogenic property, what holding was good within the temperature range of -70 DEG C -+260 DEG C uses elasticity, and has resistance to ozone, Weather-resistant etc.
Advantage.The nitrile rubber has a performances such as excellent oil resistant and aromatic solvent, but intolerant to ketone, ester and chlorination through etc. medium, because
This oil resistant sealing article is based on use nitrile rubber.
