                                             Abstract:Using the non-water reacted type two-component foam polyurethane polymer as soil anchor grouting materials have 
clear superiority compared with the traditional cement mortar. Through the contrast test of in situ stretch-draw of anchor cable, 
the results show that the solidified polymer materials will not shrink and the expansion characteristic of the materials have a 
obvious role in expanding the size of the hole which makes the ultimate pullout force of the bolt nearly double the increase; 
Polymer materials are not permeable to prevent the steel reinforcement from corrosion;Polymer materials can reach 90 % of its 
strength in 15 minutes,and do not need to maintenance,which will reduce the construction period greatly.
