Currently at the bottom of the structure, due to the pouring depth, the bottom of the bar is too dense, easy to produce due to the construction of the leakage of honeycomb, tendon phenomenon, grouting is also more difficult. This paper introduces a grouting method which is grouted from the top of the roof or the combination of the roof and the side buried pipe. The method has the advantages of simple equipment, convenient operation and low cost, and the treated concrete building meets the design requirements. 1 Technical requirements Roof grouting is in
