Description
Technical field
The present invention relates to the injection material of building concrete antiseepage, ground and Foundation Anti-seepage and reinforcing, be specifically related to a kind ofly be applicable to dealing with foundation project seepage controlling, the acrylate injection material of leak stopping and reinforcing and using method thereof.
Background technology
In dealing with foundation project seepage controlling and consolidation process, the normal acrylate injection material that adopts carries out Anti-seeping technology.At present, the acrylate injection material on market is primarily of host Magnesium Acrylate Prepared, calcium acrylate, and linking agent N, N '-methyne bisacrylamide, initiator ammonium persulfate, promotor trolamine and aqueous solvent form.In these components, easily there is chemical reaction in promotor and host, initiator, product is gone bad, therefore three can not mix common storage between two, cause when transporting and prepare, transport must be stored separately, be prepared by more than three components and just can construct, bring inconvenience to material produce, construction; The linking agent N adopted, N '-methyne bisacrylamide toxicity is comparatively large, limits the range of application of material.The gelling thing formed after adopting said components mixing, intensity is lower, and after water-swellable, anti-plasticating capacity significantly reduces.
China Patent Publication No. CN101265048A, publication date on September 17th, 2008, denomination of invention is acrylate grouting liquid and preparation method thereof, for reducing the toxicity of acrylate injection material, acrylate is adopted to replace N, N '-methyne bisacrylamide as linking agent, reduce the toxicity of acrylate injection material, but acrylate cross linked dose utilizes ester bond to connect, ester bond is easily hydrolyzed at acid or alkaline condition, causes the weather resistance of material to be under suspicion.
