Description
Technical field
The present invention relates to a kind of hydraulic engineering soft fascine mattress river bottom protection shore protection, shield beach sand soil solidifying agent and its construction method.
Background technology
The Changjiang river Deepwater Waterway Regulating Projects region top layer basis is loose silty sand ground, and lower sleeping soil layer is high-compressibility, the muck soil of low intensity.Top layer silty sand ground has thin granule, uniform particle sizes, loose feature, easily lifts because of flow action and raises and migrate.The construction of regulating structure necessarily causes the change in periphery flow field again, it will usually makes to develop and aggravate dike side beach and wash away along dike stream, and then jeopardizes stablizing for building.The bed protection structure design and construction of effective control building periphery channel scour is taken to become one of key technology of engineering success construction.
By the investigation to the current soft raft river bottom protection present situation in Yangtze Area, unrealistic using mattress dumped rocks protecting foundation, simultaneously because Engineering Zone upper soil horizon impact resilience is poor, to the globality of bed protection structure and adapt to beach face and wash away change require higher, and isostere ballast material should not be too thick in order to avoid cause the change of isostere ambient water.For the engineering of entrance of Changjiang River, it is required that isostere ballast material is uniformly distributed in isostere, thickness should not be too thick, good integrity, adapt to beach and wash away deformation, and from construction all in all, it is also desirable to the ballast material energy factorial praluction of isostere, accumulating convenience, easy construction, large stretch of sand resource near engineering location can be made full use of.
Content of the invention
The technical problem to be solved in the present invention is to provide hydraulic engineering soft fascine mattress river bottom protection shore protection, shield beach sand soil solidifying agent and its construction method that a kind of technical matters are simple and convenient to operate.
A kind of sand soil solidifying agent, its each component for including and its mass percent：
Cement 65-80wt%,
Flyash 8-16wt%,
Additive 1-5 wt%, specifically nano-calcium carbonate or aerosil etc.；
Gypsum Fibrosum 1-5 wt%,
Sodium sulfate 1-5 wt%,
Nacl 0.5-3 wt%,
Polycarboxylate water-reducer (or powder)
0.5-3 wt%,
Fast hard agent：0.2-1 wt%, specifically lithium salt compound, such as：LiCl or lithium carbonate etc.；
Methyl cellulose ether：0.1-0.6 wt%,
Cellulose ether：0.1-0.6 wt%,
Cellulose ether：0.1-0.6 wt%.
Apply above-mentioned sand soil solidifying agent to hydraulic engineering soft fascine mattress river bottom protection shore protection, protect the construction method on beach, including：By taking river silt and/or fluvial sand on the spot in riverbed bottom, fill silt firming agent, stirring be prepared into self-leveling can mortar, the mortar by pumping equipment Fast Filling rib bag and is constituted isostere then, then by filling after isostere lay and sink to the bottom；
As gravity flowing levelling mortar still has high fluidity, the complicated metamorphosis in bed body surface under water can be adaptive to, make closely to attach between isostere and bed body；Then, with the condensation hardening and strength development of gravity flowing levelling mortar, soft raft is finally consolidated into the higher hardenite of intensity, so as to isostere tight permanent is fixedly arranged at predeterminated position, constitutes mattress sinking, and guarantees the extended protection using effect of mattress sinking.
Relative to the technique effect that prior art, the application are obtained:
（1）
A whole set of technical matters are simple, easy to operate, it is only necessary on the basis of traditional sand ribbed soft mattress construction machinery, increase a blender.
（2）
Special curing agent wide adaptability, is adaptable to the sand of different clay contents（Maximum clay content is up to more than 60%）, sand directly can draw materials in water, need not dry, it is only necessary to add a certain amount of special curing agent（The 1/4-1/5 of about damp sand soil property amount）The high gravity flowing levelling mortar of mobility and pumpability is modulated into by agitated.
（3）
The gravity flowing levelling mortar good fluidity that is modulated, not only can quickly pump and easily fill rib bag, convenient construction；And, the complicated metamorphosis in bed body surface under water can be adaptive to, make closely to attach between isostere and bed body, preferably control current scour and the protection soil body.
（4）
The gravity flowing levelling mortar stability that is modulated and homogeneity are high, will not be layered or isolation problem, after implantation can closely knit molding in water, after molding, up to more than 15MPa, and prolongation over time, intensity can further improve intensity.
（5）
The gravity flowing levelling mortar cohesiveness that is modulated is good, and subparticle will not be excessive from fine and close geotextile or be oozed out, will not polluted-water.
（6）
The raw material of composition special curing agent meets environmental requirement, nonpoisonous and tasteless non-volatile, pollution-free to water body, to no toxic biological.
（7）
The engineering reliability is high, it is achieved that the mutual supplement with each other's advantages of rigid filler and flexible geotextile, and the tension of formed mattress sinking and comprcssive strength are high, resist and lift and stability against sliding height, globality and good endurance, it can be ensured that the extended protection effect of mattress sinking.
（8）
Cost is suitable, and as the raw materials such as silt directly can be gathered materials on the spot and the consumption of firming agent is few, integral construction efficiency high, its integrated cost is less than being protected using precast concrete.
（9）
The technical matters are simple, construct convenient, wide adaptability, reliability are high, form the anti-of mattress sinking lifts, globality higher with stability against sliding and durability is more preferable, the technological merit of traditional sand rib row is not only remained and as the functional requirement of loaded filter, can also be on the premise of engineering cost not be improved, mutual supplement with each other's advantages, the perfect adaptation of rigid filler and flexible geotextile is preferably realized, " soft landing, the hard protection " of isostere is really cleverly achieved.
