摘要： A concrete leveling machine is provided which propels itself over the surface of laid concrete and by use of rotating augers or oscillating stabilizers and a temper, levels and finishes the surface to a prescribed level and condition. A laser reference beam transmitted over the surface is detected by detectors attached to the leveling section of the machine and deviation of the level of the detectors from a reference level is adjusted so that the leveling section is also brought to a level required to produce the desired surface level. The machine is turned by a turntable integral with the main body which lifts the machine allowing it to turn by differential drive to its drive wheels.

摘要： The present invention presents a novel concrete floor finisher comprising a body which supports rotatable trowels with trowel blades through radial support members so that the trowels can revolve around a central shaft of the body, the body being equipped further with a driving means of the rotatable trowels, a range of equipments and a traveling means of the finisher, characterized in that the driving means of each of the rotatable trowels is a hydraulic motor connected to an engine-powered unit, and each of the motor is connected in series by hydraulic piping to be driven equally, and also discloses construction of components in detail to improve its mechanical construction adaptable to various conditions of concrete to finish. The main features of the finisher according to the present appears in the driving system to convert the driving of the rotatable trowels by electric motors or by gasline engines of prior art into a driving of hydraulic motors to eliminate their drawbacks, and moreover, following to the experiences in practical works, in utilizing of the second driving hydraulic system in adjusting the contact pressure on the surface of concrete by raising and lowering the trowels, and as well as controling the revolution of the body around the central shaft positively. That all accomplish the machine to contribute to the workability and offer a construction of the machine from various aspects of the technology. Also in the present invention, according to disclosures of embodiments, various applications and combinations are available within the scope of technical concept.

摘要： A method of placing concrete into a steel encasement. The steel encasement is erected. A plurality of first concrete injection holes are formed through the steel encasement in a heightwise spaced manner. The concrete is injected through the lowest disposed concrete injection hole into the erected steel encasement to a level below another concrete injection hole disposed just above said lowest disposed concrete injection hole. Then, the injection step is repeated in connection with a subsequent first concrete injection hole nearest to the level, to which the concrete has been placed, for placing the concrete into the steel encasement to a predetermined level.

摘要： An improved method and apparatus for placing concrete under water in an easy and effectual manner. The method comprises the steps of: immersing a tremie tube having a special valve device, into water; transferring concrete through the tremie tube; closing the valve device while the outlet of the tremie tube is kept within the deposited concrete; and lifting the tremie tube to move it to another point. The above valve device is provided with a cylindrical elastic valve member fitted in a cylindrical member forming a space to receive a fluid under pressure and, when the fluid space is supplied with a pressurized fluid, the elastic valve member is folded and expanded in inward radial directions to close up the concrete passage of the tremie tube. Another aspect of the invention is to propose the measurement of the state of deposited concrete by means of a concrete surface detecting device.
