Abstract

PURPOSE:To perform solidifying processing over a wide range, by a method wherein a ship's hull, loading a soft ground solidifying processing device, is coupled to coupling levers, each having floats at both ends through reciprocating mechanisms, through moving mechanisms. CONSTITUTION:When a working place is varied after completion of a solidifying work of a sludge layer, with reciprocating mechanisms 5 contracted, floats 6 are floated from a sludge surface, and coupling levers 3 are moved in either right or left direction through the working of moving mechanisms 4. When the reciprocating mechanisms 5 are expanded after the stop of the coupling levers 3, the floats 6 are lowered and seated on a water surface, and with the reciprocating mechanisms further expanded, the coupling levers 3 are raised to float a ship's hull 1. After the ship's hull 1 is moved in the conveying direction of the coupling levers 3 along the coupling levers 3, the reciprocating mechanisms 5 are contracted to lower the ship hull 1, which is seated on a water surface. Further, after a rotary mechanism 7 is driven to turn the coupling levers 3 around the ship hull 1, a solidifying work is effected.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an apparatus for moving a soil solidification treatment machine for soft ground, generally referred to as sludge, over sludge.

(Prior Art) Soft ground (sludge) deposited in rivers, lakes, etc., if left as is, causes various problems such as causing water pollution and adversely affecting the growth of animals and plants.

Sludge treatment methods include dredging and methods that directly inject and stir a solidifying agent into the sludge layer to solidify the entire sludge.

The latter floats the hull carrying the solidification processing machine on top of the sludge.
A plurality of stirring blades are inserted into the sludge layer and the solidifying agent is injected while stirring, and the hull is movable to enable the solidifying process of the sludge.

(Problems to be Solved by the Invention) The above-mentioned movement of the ship's body has been accomplished by connecting the ship's body and land with a wire and moving the ship's body along the wire by operating a winch, for example.

However, depending on such moving means, the hull can only be moved in one direction along the wire, which naturally limits the range of solidification processing.

In view of the above-mentioned conventional ship body movement technology in the sludge solidification process, the present invention enables the ship body and the floats connected thereto to be moved alternately in the same direction, so that the whole ship can move by itself. It is an object of the present invention to provide a moving device for solidifying soft ground that enables solidification treatment over a wide range by making it possible to rotate the direction of movement.

(Means for Solving the Problems) Means for achieving the above object will be explained with reference to FIGS. 1 and 2, which correspond to embodiments.

The present invention connects a hull 1 capable of loading a conventionally used solidification treatment machine for soft ground with a connecting rod 3 on which floats 6 are installed at both ends via a reciprocating mechanism 5, and connects the hull with a moving mechanism 4. A rotating mechanism 7 is installed between the connecting rod 1 and the connecting rod 3.

(Function) The function of the present invention configured as described above will be explained with reference to FIGS. 3 and 2.

FIG. 3(A) shows a state in which the stirring blade tI8 is suspended over the sludge layer, and the sludge is stirred and solidified while injecting the solidifying agent. To finish the solidification process in this range and change the solidification location, ), the same figure (
As shown in B), the reciprocating mechanism 5 is retracted to lift the float 6 on both sides from the sludge surface, and the moving mechanism 4 moves the connecting rod 3 in either the left or right direction in the drawing, e.g.
Move it in the direction of the arrow (see figure 0).

After the connecting rod 3 has moved a certain distance, it is stopped, and the reciprocating mechanism 5
By extending the float 6, the float 6 descends and lands on the water as shown in the figure (D).If the reciprocating mechanism 5 is further extended, the connecting rod 3 rises and the hull 1 floats above the sludge surface (Fig. E). reference).

In this state, the hull 1 is moved along the connecting rod 3 in the transfer direction of the connecting rod 3, and when it reaches a predetermined position, the reciprocating mechanism 5
When contracted, the hull 1 descends together with the connecting rod 3 and lands on the water.
The hull 1 can move a certain distance in the X direction from the position shown in FIG. 3(A).

Then, after the stirring blade 8 is suspended over the sludge layer and solidification work is performed, the hull 1 may be moved in the same manner as described above.

□.

In addition, under normal conditions, the hull 1 and the floats 6.6 on both sides are in a parallel state, but first, the floats 6.6 on both sides are floated above the sludge surface in the same manner as shown in FIG. 3(B), and the rotation mechanism 7 is driven. If the connecting rod 3 is turned to either the right or the left with respect to the hull 1 on the sludge and stopped, for example, at the position shown by the chain line in Figure 2, the sludge can be solidified in this state. Moreover, the solidification process can be performed while moving in the length direction of the connecting rod 3 which is inclined with respect to the hull 1.

(Example) Next, one embodiment of the present invention will be described.

In FIGS. 1 and 2, I denotes the hull, which can carry a conventional solidification treatment machine (not shown) that solidifies soft ground by injecting a solidification agent while stirring with stirring blades. This hull 1 connects a pair of floats 2.2 arranged in parallel, with the space between the floats 2.2 serving as a solidification processing work space.

Two parallel long connecting rods 3.3 are connected on the hull 1 so as to be movable in the left and right direction in the drawing by a moving mechanism 4.4. A float 6.6 is installed via a reciprocating mechanism 5.5.

Furthermore, a rotation mechanism 7 is installed between the hull 1 and the connecting rod 3.3, so that the connecting rod 3.3 can rotate in either direction to the left or right in FIG. 2 with respect to the hull 1. - the movement mechanism 4.4 can for example use a rank and pinion gear. That is, each connecting rod 3.3 has a rack 9 formed in its length direction, and a pinion gear 10 that meshes with the rack 9 is installed on the hull 1 side, and the pinion gear 10 is rotated by a motor (not shown).

Alternatively, an endless chain may be circulated on the hull 1, and the chain may be directly connected to the connecting rod 3.3 so as to be movable.

In any case, the hull 1 and the connecting rod 3.3 are not fixed, and the connecting rod 3.3 is movable relative to the hull 1, or the connecting rod 3.3 is moved along the length of the hull 1. As long as 1 is movable, the mechanism is not limited.

The reciprocating mechanism 5.5 may be installed for each connecting rod 3.3, or it may be fixed between both ends of both connecting rods 3.3 by a connecting plate, and one unit may be installed between this connecting plate and the float 6.6. A reciprocating mechanism 5.5 may be installed, and a hydraulic or pneumatic cylinder may be used as the reciprocating mechanism 5.5.

In addition, the rotation mechanism 7 described above has a concentric guide rail 11 installed on both floats 2.2 forming the hull 1, and a roller 12 mounted on the guide rail 11 on the top of each connecting rod 3.3. It is sufficient if the connecting rod 3.3 is rotatably provided by a motor without L2, so that the connecting rod 3.3 can turn along the guide rail 11.

In order to prevent the roller 12 from coming off the guide rail 11 and to maintain the connection between the hull 1 and the connecting rod 3.3, an auxiliary guide 1 is provided between the connecting rod 3.3 and the guide rail 11.
Set up 3.

(Effects of the Invention) The present invention has the configuration and operation described above, and allows the entire device to move by itself by floating the float 6 and the hull 1 alternately from the sludge surface and moving them intermittently in a fixed direction. becomes possible.

In particular, by floating the floats 6 on both sides, the moving mechanism 41'□・
1 Ya, □1, 14th. fart,. Kayo. □, it does not move due to frictional resistance (therefore, the connecting rod 3 moves and the float 6 can be transferred. Also, after the float 6 lands on the water,
If the moving mechanism 4 is operated with the hull 1 afloat, only the hull 1 will move along the connecting rod 3 while the float 6 is fixed on the sludge.

Therefore, after the hull 1 finishes solidifying the sludge layer in a certain area, it can move by itself and can solidify the sludge layer over a wide area.

Furthermore, since the connecting rod 3 can be rotated within the range by the rotation mechanism 7, the direction can be changed after solidifying a straight area to perform solidifying work on an area adjacent to the area where solidification has already been completed. This makes it possible to solidify a wider area.

The moving mechanism 4, the reciprocating mechanism 5, the rotation mechanism 7, etc. may be operated by an operator on the hull 1, or may be operated remotely from land.
