摘要： The present invention relates to a pile-driver, comprising a support member arranged or arrangeable in transverse direction at or on a pile, a liquid chamber which is bounded on the underside by the support member and which further comprises one or more side walls and is configured to receive a liquid therein, one or more pressure build-up chambers, an ignition mechanism configured to ignite a fuel present in the combustion space, and wherein the combustion space is configured to expand fuel present therein during combustion such that a pressure build-up takes place above the support member and the liquid present above the support member in the liquid chamber is displaced at least in upward direction away from the support member, whereby a downward force is exerted on the pile via the support member. The invention further relates to a method for driving a pile downward into the ground using such a pile-driver.
