みに採用されるようになってきた。(Prior art and problem to be solved by the invention) One of the construction methods for constructing a piled foundation in soft ground is the pile embedding method, which involves forming pile insertion holes in the ground in advance and then sinking piles into the pile insertion holes. be. This construction method has been increasingly adopted in recent years because it does not generate vibration or noise unlike the pile driving method in which piles are driven into the ground, and it is easy to construct.

ルが沈設される工事現場は、ヘドロ状物の海と化する。However, in this method, the pile insertion hole is formed by excavating the ground while supplying water, and after the pile insertion hole is formed, concrete milk is supplied to the bottom of the insertion hole. After that, the pile is sunk into the pile insertion hole, so as the pile insertion hole is formed, a sludge-like mixture of water and clay soil is sequentially discharged from the upper end of the excavation hole, and when the pile is sunk. As a result, a large amount of sludge containing concrete milk in the pile insertion hole will blow out from the upper end of the pile insertion hole, and the construction site where many piles are being sunk will turn into a sea of sludge. do.

Therefore, in the past, such sludge-like material was removed by sucking it up with a vacuum car and transporting it to another location, or by scattering a large amount of cement on the surface of the sludge-like material after the day's work was completed. The trouble caused by the sludge was eliminated by allowing the cement to absorb the moisture inside and harden the sludge.

ある。(Means for Solving the Problems) A method for dehydrating sludge-like material (hereinafter referred to as a dehydration method) according to the present invention is to remove a large amount of sludge-like material (moisture) into a pressure-resistant storage tank having a large number of drainage holes on the bottom. After accommodating the sludge (soft sludge contained in the tank), the air pressure in the space above the liquid level of the sludge is increased to sequentially push out the moisture in the sludge through the drain hole in the bottom of the pressure storage tank. This is a characteristic feature.

A sludge-like substance is poured into the upper part 2 of the pressure-resistant storage tank 10, which is made up of a required number of internal drainage pipes 9 each having a diameter of about 3 to 4 holes (for example, 3 to 4 holes in diameter). An input port 11 is provided, and the input port 11 can be closed in a sealed state with a lid body 12. Further, a communication pipe 15 connected to the discharge port of the air compressor 13 is connected to the upper portion 2 of the pressure storage tank 10 . The bottom portion 3 is removable by bolt fixing means or the like, and the upper end of the internal drain pipe 9 is fixed to the ceiling of the pressure storage tank 10, for example. Moreover, the side wall portion 5 of the pressure storage tank 10

Air is pumped into 0. Then, air pressure is evenly applied to the liquid level of the sludge-like material 19, and as a result, although the sludge-like material comes out from the drain hole 6 for a while after dehydration starts, the drain hole 6 is clogged with mud etc. After that, the moisture in the sludge-like material is pushed out toward each drainage hole 6 provided in the bottom part 3, side wall part 5, and peripheral wall of the internal drain pipe 9 of the pressure storage tank 1O, It will be discharged sequentially from 6 onwards. At that time, the particles (soil particles, etc.) in the sludge settle out and a precipitate layer gradually becomes thicker, but due to the action of air pressure applied to the top of the sludge, the moisture in the sludge is The water permeates through the sediment layer while being filtered, and is sequentially removed as clean water from the drain holes 6 provided in the pressure storage tank 10 and the internal drain pipe 9. Finally, the air in the pressure storage tank 10 will be blown out from the drain hole 6, and at this point, the water content in the storage tank has been reduced to a considerable extent. after that,
The bottom part 3 is lowered relative to the upper tank 20 to remove dehydrated material from the top of the bottom part 3. As mentioned above, the inner surface 16 of the side wall part 5 of the pressure storage tank and the internal drain pipe 90
If the outer surface portions 17 of the peripheral wall 7 are each formed to have a tapered shape, the bottom surface portion 3 can be relatively lowered easily (the inner surface portion 16, the outer surface portion 17, and the dehydrated material are easily separated). ).

となる。By the way, if the top surface of the sludge-like material is pressed mechanically with a piston rather than with air, not only water but also particles such as soil particles will be discharged from the holes provided in the bottom of the storage tank. , dehydration of the sludge becomes impossible.

The bottom part 3 of the pressure storage tank 10 is not
The drain hole 6 may be provided only in the drain hole 6.

At this time, the particles (soil particles, etc.) in the sludge settle out, and a precipitate layer gradually forms. The water permeates through the sediment layer while being filtered, reaches the bottom of the storage tank, and is successively removed by suction through the drain hole 4. Finally, air is sucked through the drain hole 22, and at this point, the water content in the storage tank has been squeezed out to a considerable extent.
