はこの外砕前浚渫や発破浚渫も知られている。[Prior Art] A dredging method is conventionally known as a method of dredging the muddy soil of a port or a river or digging the bottom of the water. This dredging method is 3
It is roughly divided into two types, and the appropriate method is determined depending on the soil quality. General dredging does not involve crushing rocks and uses a general dredger and accounts for the majority of dredging work. These dredgers include a pump boat that sucks up sand and mud along with water and sends it to the destination using pipes floating on the water, a day plow boat that scrapes up sand and mud with the tip of a shovel, and many baguettes lined up in a chain. There are two known types of boats: the get boat, which uses the upper end of a rudder to scoop up dirt and mud one after another into a mud tank, and the grab boat, which uses a grab to grab dirt and mud. Other known dredging methods include pre-crushing dredging and blasting dredging.

いう問題があった。[Problem to be solved by the invention] - Generally, when dredging polluted soil from the bottom of a port or river, as mentioned above, the soil and mud are sucked up along with water by a vacuum installed on a dredger and transported to the destination through a pipe. However, with a ratio of 10 parts water to 171 parts water, 10 times more water than the sludge is being sucked up at the same time, making suction dredging difficult.
There is a problem that equipment efficiency is poor because it requires large-scale equipment such as jars. In addition, in non-seaworthy baguette boats and club boats that scoop up and pick up sand and mud, the dirt and mud are transported to the soil carrier with a number attached to its side. There is a problem in that the earth, sand, mud, etc. must be transported to the destination or a port near the destination, which increases transportation costs.

しがった。Furthermore, when using excavated earth, mud, etc. for reclamation, mud generally contains a large amount of water at -3=, so it is less efficient at solidifying the ground for reclamation.
Furthermore, it was difficult to reuse it as civil engineering or construction material.

設備効率に劣るという問題がある。Therefore, in order to improve the solidification efficiency of the mud, it is possible to install a treatment facility at the landfill site that separates water from the mud and makes it easier to solidify the mud. Setting up a facility is likely to be subject to site constraints, and in cases where the reclaimed land is located in the same lake, river, port, etc. as the dredging site, a treatment facility is purposely built on land near the reclaimed site to remove mud. Once transported to the above-mentioned land-based processing facility and treated, it must be transported to a landfill site such as a lake, river, two ports, etc., which inevitably increases the transportation cost. There is a problem that the efficiency of the equipment is inferior.

An object of the present invention is to provide a method and apparatus for the treatment. The second purpose is to reduce the cost of transporting dug mud, and to provide a treatment method and device that does not require installation of treatment facilities on land and has excellent equipment efficiency. The third object is to provide a method and an apparatus for removing water from lakes, rivers, ports, etc. and removing only sand and mud to improve the efficiency of mud treatment later.

Then rotate the back four 5 and use the primary vibrating screen 10.
The packet 7 is opened at the top, and the mud 3 falling from inside the packet 7 is crushed by the vibrating primary vibrating screen 10 into trees,
Solids such as vinyl are separated and then passed through screen 10.
The mud 3 that has passed through is transferred to both driven screw conveyors 1
2.13, it is sent to the opening 9A and falls onto the vibrating secondary vibrating screen 15. This secondary vibrating screen 15 separates uncrushed solids such as gravel contained in the mud 3, and the mud 3 is stirred from the communication pipe 19 by the tfM20.
Water, sand, etc. in the mud 3 are uniformly sent to the mud treatment device 23 by the stirring rotor 21 which falls inward and rotates. The mud 3 is mixed with the solidification agent 24 sent from the solidification agent supply device 27 by the mixer 29, and then discharged to the hopper 33 by the belt conveyor 32. Then, the treated mud 3 mixed with the solidification agent 24 is pumped by a piston type high pressure pump 35 through the transfer pipe 34 to the pressure feed pipe 49)\ and sent to the landfill 461\.

の往復による移送に比べて移送コストの低減が図れる。In this way, in this embodiment, the water is drained from the earth, sand, mud 3, etc. on the bottom of the water, the dredging is carried out, and the dredging is carried out on the dredger 1.
Since the mud 3 etc. obtained after dredging contains less water, it is not necessary to remove the water when processing the mud afterwards, and the curing period of the mud 3 after the treatment is also shortened, thereby improving the processing efficiency. Also, before crushing, solids such as gravel are separated from the mud 3, etc., and after the mud 3 is stirred, it is mixed with a solidification agent 24, and the mud 3 mixed with this solidification agent 24 is pumped from the dredger 1 through a pipe to a destination. This means that the cost of transport can be reduced compared to the conventional method of reciprocating transport using soil transport vessels or the like.
さらに目的地に送られな泥土3は固化剤24と混合済で

設備効率に優れたものとなる。Therefore, if there is no space for this installation on land, the mud 3 mixed with the solidification agent 24 can be transported directly to the destination, which is an excellent effect, and furthermore, the cost of transporting the mud 3 can be reduced. Further, by providing the dredging means 8, the separation means 18, the mud treatment device 23, and the piston-type high-pressure pump 35 on the dredger 1 on the water, the equipment has excellent efficiency in terms of installation space on land.

合でも70〜.80%の金泥率の泥土が得られる。In addition, in this embodiment, since the mud 3 at the bottom of the water is dredged using the sealed hydraulic grab bucket 7, the mud with a gold mud ratio of 90% is dredged compared to the mud with a gold mud ratio of 10 to 15% given by the conventional vacuum method. ~95% of the mud 3 can be obtained, and the water removal step before processing the mud 3 can be omitted, increasing processing efficiency. Also, by using the sealed hydraulic grab bucket 1 to 7, the mud 3 can be collected. At this time, the diffusion of mud 3 into the water is reduced, and water pollution can be kept to a minimum. Also, even when using a regular grab bucket, it is 70~. A mud with a gold content of 80% is obtained.

広く有効利用することがでる。In addition, solids such as wood, vinyl, pebbles, etc. are separated from the mud 3 with a high gold mud ratio using the primary vibrating screen 10 and the secondary vibrating screen 15, and water is separated from the mud 3 by the stirring rotor 21 in the stirring tank 20. By stirring the mud 3 with a high gold mud ratio and sending it to the mud treatment device 23, the amount of solidifying agent 24 used can be reduced, and the mud 3 mixed with the assimilating agent 24 has a low moisture content, so it can be cured. The period is short,
It is possible to improve mud treatment efficiency and reduce waste by 1~1. Furthermore, the piston-type high-pressure pump 35 that pumps the mud 3 mixed with the solidification agent 24 separates the oil C and the mud 3 in the pressure vessel 40 into upper and lower parts due to the difference in specific gravity, and fills the cylinder 37 with the oil C and the mud 3. Since the reciprocating motion of the piston 38 applies hydraulic pressure to the mud 3 and pumps the mud 3 under high pressure, the mud 3 mixed with the solidification agent 24 is sent not only to the dredging site A but also to the land through the pressure feed pipe 49. Can be transported over long distances. Moreover, the mud 3 mixed with the solidifying agent 24 can be widely and effectively used for embankments, roadbeds, construction, backfilling, backfilling, etc. other than reclamation.

Further, as a means for pumping the mud through a pipe, air pumping or the like may be used, and various types of pumps can be used. Alternatively, a silo or the like for storing the stirred mud 3 may be provided near the stirring tank 20, and the mud 3 may be supplied from the silo 1-7 to the mud processing device 23.
