A predetermined amount of water is metered into the bottom of the hole in the annulus exterior to the pile and then dry sand is added to the water in the annulus. Various means are provided for vibrating either the pile or the external protective casing or the sand and water mixture itself. To maximize the amplitude of vibration, the frequency of vibration is varied during the grouting process to match the ungrouted length of the pile, either by continuously varying the frequency of vibration or in steps along the length of the pile. The sand and water mixture itself can be vibrated by one or more vibrating rods inserted into the mixture or by a multi-fingered sleeve which fits over the pile and into the annulus external to the pile. In some of the embodiments, the vibrated apparatus is removed while vibrating to successively compact the sand and water mixture beginning at the bottom of the hole. When using a pipe pile, the bottom of the pipe pile can be plugged during the compaction of the sand and water mixture and then removed if necessary. Dry sand is used as a ballast to prevent the pipe pile from floating when using a closed end.，下面是Method of grouting a pile in a hole involving the optimized vibration of the grouting material专利的具体信息内容。
