| Abstract: | The chemical pouring technology is to fill the fast-coagulated early-strengthened cement grout into the roadbed by a certain pressure,to extrude the water contained in the roadbed,and to re-coagulate the loose roadbed materials into the whole so as to reach the aim to enhance the bearing capacity.Based on the practical examples,the article introduces the main steps of the chemical pouring technology to reinforce the highway roadbed and the achieved effects,which has a certain reference value for the mainten... |
