The article aims at searching new structural and engineering ways to improve the efficiency of pile pressing. The study object is presented by machines and pile pressing units. The study subject is supposed to be the efficiency of pile pressing equipment and the ways to improve it. At present this problem is considered to be one of the most important and urgent issues when constructing and reconstructing foundations. Constant complication of both forms and building parts of modern structures increases the requirements to their basements and foundations to a great extent. According to the building experience, it is the foundation construction field that has the biggest potential to increase the construction efficiency and quality. Moreover, the significance of this problem is explained by a growing volume of works connected with the reconstruction of old buildings and structures, as well as industrial enterprises where a high level of dynamic and noise effects is not acceptable. The application of the existing equipment is restrained due to its structural elements imperfection and insufficient process development of industrial piles installation. Investigating and justifying of pile pressing rational technologies with the help of new equipment make the following article rather urgent. The authors provide a review and a detailed analysis of some methods and ways to increase the performance of pile pressing units. In particular, there are considered methods based on executing special technologies according to a certain sequence of sheet piling operations, as well as ways to increase the machines performance with the help of additional equipment. Special attention is paid to mechanisms comprising different anchoring systems and extra counterweight. The authors give some examples of pile pressing units that meet the requirements of high productivity, speed and efficiency under different soil and climate conditions and can be used during pile-driving works on construction sites. The pile pressing equipment structure, its operation principles and fields of application are described in the course of this study. The conclusions on the development prospects of pile pressing machines and increasing pile pressing efficiency are made. The study also reveals the most perspective systems and methods that meet the requirements of modern construction technologies.
