Abstract
The invention provides a soft foundation silt curing agent which comprises main gel powder, auxiliaries and a liquid agent, wherein the main gel powder comprises cement clinker, slag, lime, sulfate and vermiculite powder; the auxiliaries include an accelerator, an auxiliary gelling agent, an early strength agent and a water reducing agent; the liquid agent comprises polyacrylamide, polyaluminum chloride, mannitol, lignosulfonate, alkylphenol polyoxyethylene ether, tannic acid and alpha-olefin sulfonate; the accelerator is water glass; the auxiliary gelling agent is one or a mixture of two of fly ash, silicon ash and aluminum ash; the early strength agent is a mixture of sodium sulfate, aluminum sulfate and triethanolamine; and the water reducing agent is a naphthalene high-efficiency water reducing agent. By adopting the soft foundation silt curing agent provided by the invention, the problem that the silt is hard to cure due to the high organic content is solved, the silt strength is greatly improved, and the pavement performance of the silt is improved so as to meet the construction requirements as pavement subbase course and base course packing.
Description
Technical field
The invention belongs to soil treatment chemical technical field, relate in particular to a kind of solidification treatment for different moisture content earth chemical and application thereof.
Background technology
In recent years, the position of highway in the Chinese national economy comprehensive system of transport is more and more important, but be accompanied by the high speed development of highway, environmental pollution, resource scarcity problem also occur in succession, and the measure of seeking to reduce environmental pollution, reduce territory, road Ecological Loss and making full use of waste is the long-term and difficult task of of facing in present stage road construction.China is with a vast territory, and rivers and lakes are numerous, and mud quantity is very huge, but, the engineering characteristic of mud is very poor, and main manifestations is that granule content is high, water ratio is high, compressibility is large, intensity is low, penetrating quality is poor, discharging consolidation is slow, can not be directly as road filling.
Vacuum preloading process mud for make with construction be a kind of more general physics constructional method that improves at present mud bearing capacity.This method reduces mud water content by barometric point.After hydraulic reclamation falls to becoming silted up, application vacuum method is made the history that has at home more than 20 year, and long construction period is that this method is promoted the use of the major cause being restricted.
Traditional road performance method is first to excavate to abandon defective original soil, replaces a large amount of sandstone materials, and its major cause is that the curing unconfined compression strength of original soil is low, and after water suction, intensity is lower.Tradition method of constructing roadway not only will expend ample resources, pays lot of materials and takes and freight charges, also can cause larger destruction to environment.How utilizing existing original soil effective unconfined compression strength and plate body performance that improves original soil is the technical study direction that solves the problem of building the road.
Summary of the invention
The object of this invention is to provide that a kind of addition content is few, silt consolidation body intensity is high, the sludge curing agent of water-tolerant and as desilting solidifying agent, the application of building curing agent of roadbed soil and water bottom mud leakproof solidifying agent, solved that the concretion body strength that existing sludge solidification technology exists is low, sludge dewatering is difficult, external admixture material accounts for heavy shortcoming.
The technical solution used in the present invention is as follows: a kind of soft base sludge curing agent, comprise main gel pulvis, auxiliary agent and liquor, described main gel pulvis comprises cement clinker, slag, lime, vitriol and vermiculite power, wherein cement clinker 20～40 weight parts, slag 7～15 weight parts, lime 3～20 weight parts, vitriol 7～20 weight parts, vermiculite power 1～12 weight part; Described auxiliary agent comprises accelerating chemicals, auxiliary jelling agent, hardening accelerator and water reducer, wherein accelerating chemicals 3～12 weight parts, auxiliary jelling agent 20～50 weight parts, hardening accelerator 0.7～9 weight part, water reducer 0.2～2.0 weight part; Described liquor comprises polyacrylamide, polymerize aluminum chloride, N.F,USP MANNITOL, sulfonated lignin, alkylphenol polyoxyethylene, tannic acid and sulfonated α-olefin, wherein polyacrylamide 2～27 weight parts, polymerize aluminum chloride 7～15 weight parts, N.F,USP MANNITOL 20～32 weight parts, sulfonated lignin 13～20 weight parts, alkylphenol polyoxyethylene 0.02～0.7 weight part, tannic acid 0～13 weight part, sulfonated α-olefin 0.08～2.5 weight part.
Further, described vitriol is saltcake.
Further, described accelerating chemicals is water glass class; Described auxiliary jelling agent is one or both the mixture in flyash, silicon ash and aluminium ash; Described hardening accelerator is the mixture of sodium sulfate, Tai-Ace S 150 and trolamine; Described water reducer is that composition is polymethine sodium naphthalene sulfonate naphthalene series high-efficiency water-reducing agent.
Further, cement clinker is silicate cement.
Further, described slag is the active material through pyroprocess calcining.
