A pile driving system having a body, a body connection arrangement connecting the body to construction equipment, two arms on the body at least one of which is movable, and a jaw at the end of the arms having a jaw recessed connection surface formed at the inner portion of the jaw, and at least one shoe having the shoe recessed connection surface creating a symmetric profile so as to overlap the jaw recessed connection surface and corresponding to it when attached.

An electrically-driven vibratory hammer is provided, which has a power supply, is wirelessly controlled, can increase the vibration amplitude and can detect the data of the vibratory hammer in real time. Through the arrangement of storage batteries, workers can also directly work through the built-in storage batteries during construction in some remote areas, without laying additional lines, and the cost is reduced. Furthermore, a movable toothed plate previously driven by a hydraulic cylinder is changed into a clamping electric cylinder capable of directly working through the storage batteries, so that a pile body can be directly clamped without an external hydraulic pump station during working. Through the improvement, the workers can directly work without additionally laying basic equipment during construction in construction sites with incomplete facilities, the construction period is shortened, the construction cost is saved, intelligent control is achieved.

A pile press-in machine that receives reaction force from an existing pile to press in a new pile, includes: a reaction force block that grips the existing pile by a clamp to receive the reaction force; a platform that is horizontally movable relative to the reaction force block; and a press-in block that is coupled to the platform, supported to be freely lifted up and down with respect to the platform at a front of the clamp, and grips and presses in the new pile, wherein a plurality of kinds of the reaction force blocks each according to a kind and size of the existing pile are freely attachable to and detachable from one platform.

A trough plate for constructing a locked polymer anti-seepage wall includes a plate body, a guide tube, a grouting pipe and an anti-blocking head. A construction method of the locked polymer anti-seepage wall includes the steps of positioning an N.sup.th trough plate and then pressing the N.sup.th trough plate into ground, wherein N is a natural number larger than and equal to 1; engaging an (N+1).sup.th trough plate with the N.sup.th trough plate, and then pressing the (N+1).sup.th trough plate into the ground; connecting a grouting pipe of the N.sup.th trough plate with a grouting machine, pulling out the N.sup.th trough plate, and simultaneously grouting through the grouting pipe of the N.sup.th trough plate by the grouting machine; and repeating the steps (B) and (C) till the locked polymer anti-seepage wall is completed, wherein the steps (B) and (C) are repeated every time, N is automatically increased by 1.
