Abstract:In order to make the water-stop curtain play a better effect,the indoor test was firstly used to determine the reasonable cement mixing amount, and then the traditional high-pressure jet grouting pile equipment was improved, and the research results of the indoor test to the field test were applied to form a the utility model relating to a powerful stirring rotary spraying pile. The research results are as follows.In order to ensure the waterproof quality and economy of the water-stop curtain, 11% cement can be added in the actual project. In addition, the powerful agitation and rotary grouting piles formed by the use of new equipment have improved the qualified rate of water-stop curtain pile quality, saved construction costs, accelerated construction progress, and provided a reference for the development of similar projects in the future.
