Abstract

The invention provides a construction method of a microbial solidified construction waste filler equal-energy deformation compaction pile composite foundation. According to the construction method, construction waste serves as filler, a hole of a pile position is filled with the construction waste filler, meanwhile, a bacterial liquid and cementing liquid mixture is added, the construction waste filler is prepared by smashing waste concrete blocks, the construction waste filler is composed of construction waste of two specifications, and the particle size of the construction waste is 15-25 mm, and the particle size of the construction waste is 3-5 mm; the bacterial liquid is prepared from arthrobacter oxydans, providencia reevesii and bacillus pasteurii. According to the invention, construction waste fillers with different particle sizes are matched as raw materials, and the construction waste fillers are solidified by arthrobacter uric acid, Providencia reevesii and bacillus pasteurii microorganisms, so that the microorganism solidification effect is effectively improved, and the bearing capacity of the formed composite foundation is improved.

本发明提供一种微生物固化建筑垃圾填料等能量变形挤密桩复合地基施工方法。本发明施工方法以建筑垃圾作为填料，向桩位的孔内填入建筑垃圾填料，同时加入菌液和胶结液混合物，建筑垃圾填料为废弃混凝土块粉碎制得，所述建筑垃圾填料由两种规格的建筑垃圾组成，粒径分别为15～25mm和3～5mm；所述菌液由尿酸氧化节杆菌、雷氏普罗威登斯菌与巴氏芽孢杆菌制得。本发明搭配不同粒径的建筑垃圾填料为原料，采用尿酸氧化节杆菌、雷氏普罗威登斯菌与巴氏芽孢杆菌微生物固化建筑垃圾填料，有效提高微生物固化效果，提高所形成复合地基承载能力。
