“…(iv) The pressure generated by the oil acts on the base of the elevation cylinder (7). (v) The movement of the oil leaves an empty space (8). (vi) The piston ( 9) is raised due to the internal force L f created by the pressure inside the elevation chamber, which modifies the relationship between the dimensions a, b and c. (vii) The external load S f in contact with the upper end of the elevation cylinder ( 10) is lifted and sustained while the valve is kept in the hold condition.…”

“…Furthermore, the hydraulic jack is one of the most efficient types of equipment for improving traditional construction processes and structural projects. 2 The use of these jacks to lift heavy civilian structures has become relatively common, especially in the field of repair and recovery, 3 specific techniques have been developed for using them with bridges 4 and buildings, 5 including in historic and heritage projects, 6 and even as support tools in constructive/excavation processes, 7,8 rock breaking, 9 and as movement stabilizers. 10 Bottle-type jacks became popular in 1990 following developments in the automobile industry, but are also used in the medical area as components of hydraulic stretchers and inpatient elevators, in the repair of agricultural machinery, and for testing and construction operations.…”

The aim of this work was to assess the capability of a hydraulic bottle jack to control vibrations and the effects of earthquakes. The first stage of the present investigation focused on determining the axial stiffness of the apparatus, in order to relate its behavior to that of a linear elastic element. To do this, uniaxial compression tests were carried out using a manually controlled servo system. In the second stage, a conceptual application based on the field of mechanical vibrations was considered. The experimental results confirmed the hypothesis of linear behavior and showed that the stiffness coefficient had distinct values of magnitude that depended on the cylinder height. Simulations were conducted in which the frequencies and the peak displacements of an idealized SDOF system subjected to earthquake excitation were adjusted based on the experimental stiffness. It was possible to conclude that the equipment analyzed here is an effective tool for controlling vibration and reducing displacement during a seismic event, and can be calibrated according to the specific conditions of operation. This is an important aspect of safety and functionality for mechanical and structural systems.

“…To maintain the properties of the original space continuum to the extent possible, one requires micro-disturbed construction technology and control systems. Examples of micro-disturbed construction technologies include shield tunnels with a new cryogenic sealing process for launch and reception [183] and pneumatic caissons with remote-control technology [184]. According to Zhu et al [185], the system includes three parts, namely survey, prediction, and decision before the construction, monitoring, and feedback control during construction, and longterm prediction and control after the construction.…”

The utilization of urban underground space (UUS) offers an effective solution to urban problems but may also negatively affect urban development. Therefore, UUS development needs better concerted guidelines to coordinate various urban systems and the multiple components of the underground world. Sustainable Development Goals (SDGs), which should be viewed as important yardsticks for UUS development, do not explicitly mention urban underground space, although many of them are affected by both the positive and negative consequences of its development. To fill this gap, this review lays the foundations of relevant UUS concepts and uses exemplary cases to reveal that 11 out of 17 SDGs can be linked with UUS uses. These linkages also manifest that land administration, integrated planning, architectural design, and construction technology are critical dimensions for increasing the contributions of UUS to the realization of SDGs. To achieve multi-disciplinary synergies among these four critical dimensions, a collaborative approach framework based on spatial data infrastructure is required. Thus, this work provides academics and practitioners with a holistic view of sustainable UUS development.

In order to study the mechanical behavior of open caisson foundation in the Wenzhou area, combined with the characteristics of the soil layer in the Wenzhou area, based on the field measurement and investigation of a wide range of engineering cases, this project studies the mechanical properties of open caisson sinking in soft soil stratum and optimizes the construction parameters through the combination of field measurement, numerical simulation, and theoretical calculation, while ensuring the smooth sinking of the open caisson, control the deformation effect of the soil around the open caisson to serve the urban construction. The research results can directly serve the whole process of design, construction, measurement, and control of open caisson engineering. It has engineering practical significance and can be used as a reference for similar projects.
