Embodiment
Below in conjunction with accompanying drawing, the embodiment to the present invention is described in further detail, so that technical solution of the present invention is more
It should be readily appreciated that and grasp.
A kind of tunnel, including concrete layer 1, annular girder steel 2 and reinforcement 3, the reinforcement 3 are welded on annular girder steel 2
On, annular girder steel 2 is welded using the girder steel head and the tail of many arcs, keeps easy to assembly, annular girder steel 2 uses quality structure
Steel, this kind of steel must ensure chemical composition and mechanical property simultaneously.Its trade mark represents average carbon in steel using two digits
The number (w с × 10000) very much of mass fraction.Such as 45 steel represent that the mass fraction of average carbon in steel is 0.45%；08 steel is represented
The mass fraction of average carbon is 0.08% in steel, and carbon constructional quality steel is mainly for the manufacture of machine parts.Typically will be through overheat
Handle to improve mechanical property.
The concrete layer 1 is cast in the annular outside of girder steel 2, and the outside of concrete layer 1 is provided with polyurethane film 4, gathered
Urethane film 4 has thermal-insulating waterproof effect, conventional monomer such as toluene di-isocyanate(TDI), '-diphenylmethane diisocyanate etc..It is polynary
3 classes of alcohol point：Simple polyalcohol（Ethylene glycol, glycerine etc.）；Polyester oligomer containing terminal hydroxyl, gathers for preparing polyester-type
Urethane；Polyether oligomers containing terminal hydroxyl, for preparing EU.Polymerization is different with material character.Close
Low molecular weight diol is first prepared during elastomer-forming, then is reacted with excess aromatic or aliphatic isocyanates, isocyanide is generated
Acid group（-NCO）For the prepolymer of end group, then with polyalcohol chain extension, obtain thermoplastic elastomer；If with diamine chain extension and further
Crosslinking, obtains casting type elastomer.Prepolymer hydrazine or diamine chain extension, obtain elastomer, and hot repressing is shaped to film.
It is provided with the annular girder steel 2 in first roadbed 5 and the second roadbed 6, the roadbed 6 of the first roadbed 5 and second
Bar-mat reinforcement 7 is respectively arranged with, concrete is poured into a mould in outside, using strong concrete raw material, is chosen according to following process：Water
The determination of gray scale.The formula for calculating the intensity that can not use normal concrete of the high-strength concrete ratio of mud, should be provided according to experiment
Material is counted, and is proposed the relational expression of concrete strength and the ratio of mud, is then used as Tu Fa or calculating method is obtained and concrete matched
The corresponding ratio of mud of intensity processed.When carrying out concrete strength test using multiple different match ratios, one of them should be
Benchmark match ratio, the ratio of mud of other match ratios preferably increases and reduces 0.02~0.03 respectively compared with benchmark match ratio.Gather materials use
Amount：The rubble consumption VS of every cube of every cube of rubble consumption G0 high-strength concrete is 0.9~0.95m3, then every cube of medium stone
Quality is：G0=VS × rubble loose volume weight, every cube of sand consumption S0S0=[G0/ (1-QS)] QSQS- sand coarse aggregate ratio should be true through experiment
Fixed, general control is in the range of 28~36%.Water consumption：When calculating mix proportion of high-strength concrete, its water consumption can use common coagulation
Corrected on the basis of native water consumption with water-reducing rate method.Deduct and subtract by additive in the concrete water amount for not mixing additive
The diminishing amount that water rate is calculated is the water consumption of concrete when mixing water reducer.Now noting must be outer by testing determination
Plus the water-reducing rate of agent.Cement consumption：When producing high-strength concrete, the consumption of cement is vital, and it directly influences water
The cohesive force of earth rubber sand and aggregate.In order to increase the ratio of colloid ramming material in mortar, cement content is higher, but it is noted that
It is that cement consumption is again unsuitable too high, exotherm rate otherwise can be caused during aquation too fast or the problems such as excessive amount of contraction.It is high-strength mixed
Solidifying soil-cement consumption is general no more than 550 kg/m3.Trial mix is adjusted：To the match ratio result obtained by calculating will by trial,
Trial mix is verified.Mixing high-strength concrete must use forced mixer, want high frequency pressurization to vibrate when vibrating, it is ensured that mix
It is closely knit.It is noted that trial mix amount should be not less than the 1/4 of mixer rated capacity, the agitating mode of concrete and additive mix method,
The method used when preferably with actual production is consistent.The determination of match ratio：When mix actual density and calculated value difference it is absolute
When value is no more than calculated value 2%, it can not adjust.Pressed during more than 2%《Design of common concrete proportioning code》JGJ55—2000
Regulation is adjusted correspondingly.After concrete mix is determined, the repetition that should be carried out to match ratio no less than 6 times, which is tested, to be carried out
Checking, its average value is not lower than the intensity level of preparation, it is ensured that its stability.
