Erosion plate thickness accounts for the 0.1%～20% of anticorrosion position gross thickness.Although the utility model has been made certain to steel pipe sheet
Anti-corrosion treatment, but Steel material does not ensure that in complicated underground environment long-time is not exposed to corruption using rear section of jurisdiction
Erosion, therefore, even if which has made certain process to steel pipe sheet, but can not meet growing Tunnel Engineering construction.Right
In concrete material, at this stage mainly based on C50 concrete classifications, there is problems with using process in which：1st, general
Concrete pipe sheet design thickness is the 1/20 of circle diameter, and as Tunnel Engineering develops, circle diameter constantly increases, tunnel segment structure
Size is also increasingly thicker, and weight is also increasing, causes very big inconvenience to construction and installation, while also constantly expand excavating periphery
Diameter, construction cost raise serious；2nd, concrete material is heterogeneous material, occurs internal fine fisssure in the manufacturing process of section of jurisdiction itself
Line causes anti-permeability performance not enough, occurs infiltration phenomenon after causing to install and use, therefore most of engineerings to slip casting outside section of jurisdiction again
Carry out secondary lining-up or carry out water repellent treatment, to increase anti-permeability performance；3rd, occur in the manufacturing process of section of jurisdiction receipts face cracking and
Construction and installation process ftractures, and opposing underground is saline and alkaline to wait corrosive medium performance not enough, needs special surface to process；4th, material itself resists
Fiery poor performance, own material belong to fragile material, and local antiknock, shock resistance are poor, breakage of caving in easily occur.

Further, the Binder Materials is the mixture of alumina cement and portland cement, the alumina cement and silicon
The mass ratio of acid salt cement is 1:5～10.
Alumina cement is also called refractory cement, and, based on calcium chlorate, which generates gel aluminum hydroxide in hydration process for which,
Diaphragm is formed on concrete particle surface, therefore which has preferably corrosion resistance.The early strength of alumina cement is promoted
Rate is considerably beyond portland cement, but its final hydration product occurs crystal transfer and causes intensity decreases.Work as alumina cement
When being used in mixed way with portland cement, which can accelerate the condensation of portland cement, alleviate the heat of hydration, also, select suitable high
Aluminium cement addition and portland cement addition, can cause concrete to obtain satisfied hydrating capacity, both have higher
Early strength, also remains good later strength.
Further, mixture of the mineral admixture for slag, ceramic, silica flour and flyash, the slag,
The mass ratio of ceramic, silica flour and flyash is 1:1～3:3～5:1～2.Alumina cement is in later strength as described above
Decrease, be the reason for important among these, the product that alumina cement was formed under aquation initial stage or low temperature is aluminium hydroxide
Colloid, plays enhanced effect between the crystal that concrete surface forms diaphragm and fills, and after temperature is improved, aluminium hydroxide turns
Be changed into crystal gibbsite, the humidification of colloid is not only reduced in the transition process of this crystal formation, but also discharges knot
Brilliant water and cause porosity increase.Therefore inventor is had found by numerous studies, by slag, silica flour, ceramic and fine coal
The combination of ash, shows gelling property in concrete preparation process, generates hydrated calcium silicate, the aquation aluminium with gelling ability
The compounds such as sour calcium, aquation aluminium calcium sulfate, and be interweaved with the aluminium hydroxide that there is gelling ability equally in generating process,
Form a high intensity gelling system.The gelling system of this high intensity can be prevented when later stage aluminium hydroxide is in crystal transfer
Caused porosity becomes big shortcoming.Additionally, specific with the addition of ceramic, except enabling mineral admixture to be filled in coagulation
In the hole of soil so that grain composition is more reasonable, reaches preferably density state, further reduce water consumption, so as to reduce
The ratio of mud, improves outside the density and impermeability of concrete, and also achieving prevents the aquation of alumina cement and portland cement from producing
Thing causes the unstable disadvantage of the volume that crystal transfer is produced in high temperature and low temperature repeatedly change procedure.

Into structure, and the filling of other components both reduced the porosity in unit volume, more because larger particles material is by less
Granule materials are surrounded, and the structure of a high efficiency high strength is integrally formed, the stress collection that external force can be disperseed when bearing external force to be formed
In, lift opposing of the concrete product to external force.
Further, mixture of the dispersant for high efficiency water reducing agent, air entraining agent, methyl alcohol and triethanolamine, each component
Mass ratio be 1:0.00015～0.0003:0.002～0.005:0.02～0.04.Dispersant can mix the mixing of concrete
In thing, play scattered effect to concrete particle, so as to improve the workability of concrete, improve the packing of concrete and strong
Degree, in addition, although dispersant simply plays an important role in concrete coagulation process, the work risen to the later concrete for hardening
With little, but, inventor is had found by the combination to above-mentioned dispersant and the optimization of consumption, by above-mentioned means, dispersant
Interpolation can also promote alumina cement with the production of other component reactions containing the mineral for combining water, by the quick shape of this mineral
Into, can cause inside concrete at short notice have relatively low residual water, produce because of moisture evaporation so as to reduce concrete
The big contraction of life, prevents from evaporating the cohesive force to form hole and reduce inside concrete.
