Internet of Things knot wraps up the aggregate structure centered on sand particle, and then improves the intensity of cement grouting material.In addition, in cement plasmoid humor
It mixes sand and also brings along negative effect, sand belongs to granular material, has certain peptizaiton, needs to make with modifier
With to solve the problems, such as this.
Compared with existing rich water karst large-cavity strata anti-seepage reinforcing foundation treatment technology, advantages of the present invention has：(1) lead to
It crosses and adds in mineral additive sodium metaaluminate in the cement bonded sand cream slurry of the present invention and adjust the proportioning of modifying agent, it can be achieved that water
The indexs such as proportion, syneresis rate, presetting period, consistency, fluidity, anti-shearing yield strength, viscosity of silt particle cream slurry controllable and
The calculus rate and intensity of Seed harvest are adjustable, while performance is released in stability, thixotropy and water resistant the stream punching for improving cement bonded sand cream slurry
And anti-permeability performance, it is made to meet engineering design requirements.It solves existing plastic viscosity cement mortar early period and yield stress is smaller,
Slurry material setting time is longer, and the deficiencies of weak is released in the punching of water resistant stream；(2) it is in addition, certain by being mixed in cement bonded sand cream of the present invention slurry
The sand of amount, makes its coarse aggregate as cement at, hardness higher the features such as larger for cement volume using sand facies, can be to water
Mud overall structure plays a supporting role, and the hole quantity that can effectively reduce cement mortar can simultaneously play particle metathesis
And the cementation of cement-hydrate, and then improve the intensity of cement grouting material；Mixing sand also has certain technology, economy and ecology
The advantage of aspect, it is higher to solve common rapid hardening slurry material cost, for the basement process of rich water karst large-cavity strata, needs big
The problem of measuring consumptive material.
To sum up, the novel controllable cement bonded sand cream slurry injection material for being suitable for the grouting filling of rich water karst large-cavity strata of the invention
Material takes full advantage of the advantage of mineral additive and sand, be it is a kind of have good pulp stability, adjustable slurry material controllability,
Performance and higher consolidating strength, and environmental protection, cheap preferred grouting material are released in stronger water resistant stream punching.In ground work
In journey, hydraulic engineering foundation treatment engineering, as the solution cavity of the dam foundation, underground power house, tunnel perimeter karst, rivers and lakes dyke class are rich
The anti-seepage reinforcing of water karst large-cavity strata, novel controllable cement bonded sand cream slurry grouting material can be adjusted according to actual requirement of engineering
The volume of corresponding modifying agent and sand, to meet design specification requirement.
