A platform 4 is movably mounted on the rail 3, and a first table 5 tiltable in the left-right direction and a second table 7 tiltable in the front-rear direction are mounted on the platform 4 in an overlapping manner, and a stirring device is mounted thereon. Install 14. Each table is supported by the hydraulic cylinders 6 and 8 so that the tilt angle can be adjusted.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hardening treatment device for hardening soft ground or sludge in a port, a river, a landfill, or the like.

[0002]

[Prior Art]

 When the soft ground is hardened, unevenness of the soft state of the ground and various loads and frictional biases acting on the hull often cause the pontoon hull equipped with the hardening machine to tilt. On the other hand, an agitator equipped with a shaft equipped with a stirring blade that stirs while pouring the hardening agent is fixed to the ship's hull, so the shaft also tilts when the hull tilts, and as a result, the hardening process is performed by the stirring blade. The area to be covered is also inclined. Moreover, since this inclination is not always constant, in the processing work in which the processing device is moved and the curing process is repeated, an uncured portion remains or an uneven curing state occurs. There was a problem of becoming.

[0003]

[Problems to be solved by the device]

 The problem of the present invention is improved so that even if the ship's hull is tilted due to uneven ground or unbalanced load acting on the ship's hull, the vertical hardening process can always be performed without being influenced by the tilt. Another object is to provide a hardening treatment device for soft ground.

[0004]

[Means for Solving the Problems]

 The gist of the present invention, which has solved such a problem, is to provide a platform movably on rails laid on the deck of a barge, and to provide a tiltable table in the front, rear, left, and right directions at the rear end of the platform. Is supported by a support mechanism that can adjust the tilt angle of the table surface in the front-rear direction and the left-right direction, and a stirring device in which a rotating shaft of a stirring blade for pouring and stirring the curing agent is vertically movable is provided. It is a hardening treatment device for soft ground characterized by being installed on a table.

[0005]

[Action]

 In the apparatus for hardening treatment of soft ground of the present invention, an agitator equipped with a rotating shaft of an agitating blade, which is the main body of the hardening operation, is installed on a tiltable table. Since the table is supported by a support mechanism that allows the tilt angle to be adjusted freely, the table can be quickly and easily leveled even if the barge hull is tilted due to ground conditions or load imbalance. Can be That is, since the shaft of the stirring blade can be kept vertical, uniform hardening treatment can be performed.

[0006]

【Example】

 Examples will be described with reference to the following drawings. FIG. 1 is a side view showing an embodiment, and FIG. 2 is a plan view of the same.

In the soft ground hardening treatment apparatus 1 of the present embodiment, the piers 2 and 2 ′ are connected in parallel at a predetermined interval, and the rail 3 is horizontally mounted on the deck of the piers 2 and 2 ′. is doing. A platform 4 is arranged on the rail 3 so that it can run freely. On the platform 4, there is provided a first table 5 which is tiltable in the left and right directions. The first table 5 is tiltably supported by a support shaft 5a at the center of the first table 5, and is supported by the left and right hydraulic cylinders 6. The tilt angle can be adjusted. A second table 7 which is tiltable in the front-rear direction is mounted on the first table 5, and the second table 7 is supported at the rear end of the first table 5 so as to be tiltable in the front-rear direction around a support shaft 7a. In addition, since the front end of the second table 7 is supported by the hydraulic cylinder 8, its angle can be freely adjusted. Further, the second table 7 projects rearward from the barge 2 so that it does not hinder the hardening process. Reference numeral 9 is a traveling motor of the platform 4, 10 is a hydraulic unit for the hydraulic cylinders 6 and 8, 11 is a pump unit, 12 is a driver's cab, and 13 is an agitator tank.

A stirring device 14 is erected on the second table 7, and a shaft 16 of a stirring blade 15 is vertically movable in the stirring device 14. Reference numeral 17 is a stirring motor, and 18 is a vertical movement motor for the shaft 16. At this time, if the stirring device 14 is configured to be divided into upper and lower stages, it is convenient when the processing device is transported.

In the hardening operation, the hardening agent in the agitator tank 13 is pumped out, and the inside of the shaft 16 is used as a flow path to be poured out from the pouring port 19 of the stirring blade 15, and at the same time, it is hardened by stirring with the surrounding soft ground. Let

In the above-mentioned embodiment, the two barges are connected to each other, but of course one ship may be used, or a larger number of hulls may be used. Further, if the shaft of the stirring blade is of a joint type, the height of the stirring device can be kept low.

Further, it is more convenient to provide a control means for detecting the inclination of the hull and automatically controlling the support mechanism of the table so as to keep the table horizontal.

[0012]

[Effect of the device]

 Since the present invention is configured as described above, even if the hull of the pontoon is tilted, the agitator equipped with the shaft for moving the agitator blades up and down can always be maintained in the vertical state. Therefore, it is possible to carry out a uniform curing process without leaving an untreated portion or causing a non-uniform treatment state during the curing process.
