Pier cushion cap foundation grouting construction technology
The invention discloses a pier cushion cap foundation grouting construction technology which comprises a hole drilling step and a grouting step. According to the grouting step, grouting materials and a grouting method are included. According to the grouting materials, main materials are complex portland cement, the water cement ratio is 0.4-0.45 : 1, underwater non-dispersing type additives according to a certain ratio of cement content are mixed for use, the weight ratio of the underwater non-dispersing type additives based on the formula is that high-performance water reducing agents : nonionic polyacrylamide : cellulose ether = 6-10 : 1 : 1, finished products are powder, and according to the weight ratio, the mixed quantity of the underwater non-dispersing type additives is 0.4%-0.6% of the cement content. According to the pier cushion cap foundation grouting construction technology, the stability of grouting thick liquid under a dynamic water environment can be guaranteed, the grouting thick liquid is not diluted and does not run off, and accordingly grouting effect is guaranteed.
