Abstract
The special clay curing slurry has controllable pressure-coagulation and early strengthening times, anti seismic, dilution resisting, dynamic water pressure resisting, antifreezing and other properties. It has high hydroscopicity, good grouting performance, early solidification property and powerful water dilution resistance, and may be used in grouting under flowing underground water, large cave and large cracking. The slurry has its initial coagulation time, final coagulation time and early strength controllable in wide range, so that it may be used in intermittent grouting and repeated grouting. It has strong chemical nonreactivity to resist erosion of underground water, acid and alkali, reliability over 95 % and coagulated body pressure strength up to 2-5 MPa . The present invention may be used in reinforcing engineering and building permeation resisting curtain and other civil engineering.
Description
The present invention relates to a kind of novel clay soil hardening slurry to being adopted in enforcement grouting and reinforcings such as engineering foundation and earthen structure and side slope and the construction seepage proof curtain engineering.Belong to constructional materials.
Mine construction in the construction work and mining engineering, traffic tunnel engineering, side slope training works, city underground engineering, underground people's air defense and defence construction, base pit engineering, dyke seepage control stabilization works and other underground geotechnical engineering etc. mostly all need to adopt the way of slip casting to implement antiseepage water blockoff and consolidation process, to guarantee engineering smooth construction and safe operation in the future.At present, the cement solidification slurries of extensive use both at home and abroad and clay hardening slurry etc. remain in initial setting time and final setting time and are difficult to control and shortcomings such as low, the anti-flowing pressure poor performance of adjustment, antidetonation and anti-permeability performance, anti-underground (mineralising) water and acid, alkali radical ion erosiveness deficiency, and causing ground stabilization, sealing leak stopping, anti-collapse workmanship of preventing sinking etc. and reliability to become has a difficult problem to be solved.The dyke seepage control consolidation process is especially true.Internet according to domestic and international dozens of site databases such as China National Library, china academia JOURNAL ABSTRACTS, CSCD, Chinese science and technology paper statistics and analytical database, CNKI, website, Europe and Univ California-Berkeley library searches the result, there is no the reported in literature similar to the present invention both at home and abroad.
The objective of the invention is to: a kind of clay hardening slurry that early coagulates with early strong (time is controlled), antidetonation, anti-dilution, anti-underground water flowing pressure and characteristic such as freeze proof and construction simple and inexpensive that has is provided, solves difficult problems such as ground stabilization, sealing leak stopping, anti-collapse anti-heavy workmanship and reliability that exist in the civil engineering.
The present invention realizes as follows: by theory analysis and the experimental study to the used raw-material mineralogical composition of extraordinary hardening slurry, chemical composition and mixing back chemical reaction, adopt the mathematical optimization analytical technology to influence size performance and in soil layer the key factor of Diffusion Law and action effect carry out squama and select, thereby, determine material mixture ratio index and the technological process that special clay hardening slurry and corresponding unique construction agent thereof are made with this for special clay hardening slurry and corresponding unique construction agent thereof preparation provides the call parameter that accords with various actual conditions.Again according to on-the-spot slip casting test, research and the construction technology of summing up special clay hardening slurry slip casting and service condition thereof etc.Determine that the slurries compound method is as follows: slurries are made up of unique construction agent and major ingredient and water.The unique construction agent is to be all 0.04～0.20mm by raw material particle size, and raw material weight is than the solid state powder that is mixed with for silica 1 0～37%, calcium oxide 12～43%, calcium aluminate 15～40%, aluminum potassium sulfate 6～54% physical mixed.Major ingredient is to be that the Portland cement of 0.05～0.10mm or slag cements, particle diameter are raw material less than the clay of 0.05mm by particle diameter, by weight being mixed with solid mixt for cement 20～50%, clay 50～80%.Press again! Weight ratio is the slurries that unique construction agent 2～20%, major ingredient 37～50%, water 40～60% mixs evenly are mixed with.When construction is used,, get job site clay allotment slurries sample according to the requirement of concrete engineering design technology index, through maintenance and detect its performance up to standard after, determine the accurate proportioning that is suitable for.
Characteristics of the present invention are: special clay hardening slurry has the water absorption rate height, flow and pumpability is good, it is high and controlled to force the way across in early days, initial setting time and final setting time are adjustable, and characteristic such as Qiang Kangshui dilution.The construction simple and inexpensive.Can be (even in bigger groundwater velocity and higher moving under the Groundwater Flow state
Under the water pressure situation) and cavern and big crack condition under carry out slip casting.Main materials-clay can be gathered materials on the spot, and has reduced the cost of slurry material.The initial setting time of slurries can all can be looked concrete condition to dozens of minutes, final setting time and early stage intensity etc. in several seconds and can be adjusted on a large scale, thereby can carry out gap slip casting, repetition slip casting to improve slip casting effect.Slurries solidify the formed calculus body in back and have good seismic resistance greatly because of plasticity.It is good that the calculus body that congeals into because of slurries has a whole water plugging effect that dilatancy is good, transmission coefficient is little, the good airproof performance characteristics make its grouting curtain.Has the ability that good anti-underground (mineralising) water and acid, alkali radical ion corrode by the calculus body of forming than the clay mineral of extensive chemical inertia.The reliability of slurries surpasses 95%.Ground and dykes and dams etc. adopt the transmission coefficient after special clay hardening slurry slip casting is handled to reduce by 2～3 orders of magnitude.The calculus body compressive strength of slurries (maintenance in 28 days) reaches 2Mpa～5Mpa.Compare with the slurries of existing traditional slip casting (be as water/binder ratio 0.5: 1 cement grout), the unit price of special clay hardening slurry has reduced more than 30%.
Most preferred embodiment of the present invention is as follows:
With Huangshi section river bank, Hunan Province, Chinese the Changjiang river clay soil property is example.In the dam reinforcement seepage control project, select for use: the structural agent raw material particle size is all 0.05～0.08mm, and raw material variety and weight ratio are: silica 1 2%, calcium oxide 31%, calcium aluminate 33%, aluminum potassium sulfate 24%.Major ingredient is to be that slag cements, the particle diameter of 0.06～0.08mm is raw material less than the clay of 0.05mm by grain, by weight be that cement 38%, clay 62% are prepared.Again by weight evenly being mixed with slurries for structural agent 16%, major ingredient 40%, water 44% mix.The reliability of slurries is 98%, and transmission coefficient reduces by 3 orders of magnitude, and slurries calculus body compressive strength is 2.6MPa, and the unit price of slurries reduces by 38%.
