Concrete leveling apparatus

An apparatus for horizontally casting concrete comprises a horizontally foldable multilink support arm composed of an attachment frame, a proximal boom, intermediate booms, and a distal boom which are pivotally coupled by joint tubes, a drive mechanism composed of worm wheels mounted on the joint tubes and worm gears mounted on the booms and held in mesh with the worm wheels for enabling the support arm to move in articulatory motion, a concrete pressure-feed pipe extending from a pump along the booms and through the joint tubes with swivel joints, and an attachment jig mounted on the attachment frame for being mounted on a column.

An apparatus for treating sludge deposits comprising a girder, first running means for moving the girder in a direction perpendicular to the longitudinal direction of the girder, kneading means held on the girder, second running means for moving the kneading means through a holding frame in a direction perpendicular to the longitudinal direction of the girder and lift means for bringing up and down the kneading means while a chemical is fed from the kneading means is disclosed. The method for treating sludge deposits by using this treating apparatus comprises repeating the step of treating a sludge deposit layer in a band-like area by simultaneously driving the second running means and lift means and the step of driving the first running means, whereby a sludge deposit in a broad region is continuously and promptly treated.

Apparatus and method for treating sludge deposits

Sludge deposit is stored in a sludge deposit receiving hopper, and the stored sludge deposit is fed onto a belt conveyor and transferred to a mixer. A hardener is fed to this mixer from a hardener hopper. A conveyor belt is disposed on the belt conveyor to measure the quantity of the sludge deposit transferred by the belt conveyor. According to this measured value of the transferred sludge deposit, the quantity of the sludge deposit fed from the sludge deposit receiving hopper and the quantity of the hardener fed from the hardener hopper are controlled. The sludge deposit is mixed and kneaded with the hardener, and the sludge deposit is solidified.

Apparatus for treatment of sludge deposit

An apparatus for treating sludge deposits comprising a girder, first running means for moving the girder in a direction rectangular to the longitudinal direction of the girder, kneading means held on the girder, second running means for moving the kneading means through a holding frame in a direction rectangular to the longitudinal direction of the girder and lift means for bringing up and down the kneading means while a chemical is fed from the kneading means is disclosed.

A method for constructing a tubular pile foundation in soft soil formations comprises agitating the soft soil to form an agitated region like a tube with single annular section or tubes with conjugated annular section at a time, injecting chemical hardener and mixing it with the soft soil to solidify the agitated region in situ into a tubular pile or conjugated tubular piles. By repeating the foregoing steps, the structural wall of piles is constructed to provide bearing capacity with the soft soil formations.

Method for constructing a reliable foundation in soft soil formations

The present invention relates to a device for constructing a tubular pile foundation in soft soil formations. Where in use, the device is suspended into the soft soil from a crane or a derrick on the earth or a working barge off shore. The device for stabilizing a body of the soft soil comprises a machine box holding driving means, driving shaft means connected to said drive means, agitating barrel means for stirring the soft soil disposed at the lower end of said driving shaft means, said agitating barrel means having a plurality of agitating blades, and a chemical hardener feeder system for injecting the hardener into the soft soil to form solidified tubular piles, said chemical hardener feeder system including swivel joints, delivery pipes and injection nozzles. The device can be moved upward and downward in course of constructing tubular solid piles in situ by agitating and mixing the soil with the hardener to provide the high bearing capacity to the soil layers.
