Slurry filling interlayer method building fertilizer tank backfilling construction method
The invention provides a slurry filling interlayer method building fertilizer tank backfilling construction method. A cement slurry pump is used for pouring and tamping stirred and filtered slurry into waste residues which are virtually filled in a fertilizer tank, a layer of waste residues is filled, a layer of slurry is poured, the slurry flows and permeates into the waste residues, a compact waste residue and slurry mixture is formed, the mixture is solidified to form a cement waste residue solidified body, and the functional requirements for the strength, the seepage resistance, the shrinkage resistance and the falling resistance of fertilizer tank filling can be met. The slurry comprises cement slurry, double-liquid slurry or chemical slurry. The method has the advantages that the construction speed is high, and the construction cost is low; the crushed waste residues in the fertilizer tank are easily poured, permeated and solidified to form the cement waste residue solidified body, the functional requirements for the strength, the seepage resistance, the shrinkage resistance and the falling resistance of fertilizer tank filling can be met, and the strength of the cement waste residue solidified body can reach 0.4-2.0MPa; and the permeability coefficient reaches 1.0*10<-6>cm/s; steel beams can be disassembled and recycled on the premise of ensuring safety, and economic and environmental protection benefits are obvious.
一种浆填夹层法建筑肥槽回填施工方法，利用水泥浆泵，将搅拌并过滤好的浆液向肥槽内的虚填的废渣进行浇灌夯填，填一层废渣，浇灌一层浆液，通过浆液的流动并渗透进废渣内，形成密实的废渣与浆液的混合体，该混合体凝固后形成水泥废渣固结体，能够满足肥槽填筑的强度、防渗性、防收缩、防陷落的功用要求；所述的浆液包括水泥浆液、双液浆液或化学浆液。本发明的优点是：施工速度快，施工成本低：很容易将肥槽内的粉碎后的废渣，浇灌渗透，凝固后形成水泥废渣固结体，可满足肥槽填筑的强度、防渗性、防收缩、防陷落等功用要求，水泥废渣凝结体强度可达0.4～2.0MPa；渗透系数达1.0*10‑6cm/s；可以实现在保证安全前提下钢梁拆除回收，经济环保效益明显。
