Construction method of deep stirring and jet grouting compound pile waterproof curtain
The invention discloses a construction method of a deep stirring and jet grouting compound pile waterproof curtain, and a construction method of a deep foundation pit waterproof curtain having a waterproof requirement. Firstly, the stirring pile beating construction is performed for a low-strength soil layer above a rock layer by a three-shaft stirring pile machine; then, a drilling machine is used for predrilling the condensed three-shaft stirring pile machine at the upper part and the high-strength soil layer at the lower part and drilling into the rock layer at the bottom; and finally, the high-pressure jet grouting pile construction is performed for the lower end of the three-shaft cement stirring pile to the rock layer through leading jet grouting cement slurry into the predrilled holes by a high-pressure jet grouting pile machine, so that the three-shaft cement stirring pile and the high-pressure jet grouting pile are built to form a waterproof pile body to form a continuous closed wall. It has been found that the method not only solves the waterproof problem of the deep foundation pit (in particular, a deep foundation pit rock socket), but also achieves the effects of saving the cost, rising the construction speed, reducing the labor intensity and shortening the construction period.
