Description of the Related Art As a drain casting vessel, a casting pipe is used in which a casing pipe is attached to a leader so as to be vertically movable, a drain material is fixed to a tip of the casing pipe, and the casing pipe is cast into the ground. I have. In that case, it is necessary to supply the drain material in parallel with the casting.However, with a conventional casting ship, the drain material package is temporarily lifted to the top of the casing pipe, and the drain material is stored in the casing pipe. Met.

[0003]

SUMMARY OF THE INVENTION The above-mentioned conventional drainage ship has the following problems. <a> Dangerous and time-consuming operations such as lifting a heavy and heavy drain material package to the top of a high casing pipe must be repeated. <B> In order to avoid such dangerous work, a structure in which the drain material a is set on the turntable b on the deck and pulled out as shown in FIGS. In that case, the tip of the drain material a is wound around the uppermost reel c and then stored in the casing pipe d. In that case, since the casing pipe d moves up and down the distance e from the upper end to the lower end, the drain material a is exposed during that time. The exposed drain material a is easily shaken by the wind and may be damaged by hitting the leader, or may be contaminated with oil and greatly impair the water absorption. <C> A structure in which the space from the uppermost reel c to the upper end of the casing pipe d is protected by a bellows tube or the like is also conceivable. However, the elevating distance e of the casing pipe d is, for example, 4
It is extremely large at 0 to 50 m. Therefore, it is impossible to obtain such an amount of contraction with a bellows, and it is difficult to actually realize such a device.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and does not require the operation of lifting a heavy drain material package to a high place and can supply the drain material accurately. The purpose is to provide a casting vessel.

[0005]

In order to achieve the above object, a drain casting boat according to the present invention has a leader installed on a ship, and a casing pipe is attached to the leader so as to be vertically movable. In a casting vessel where the drain material is fixed to the tip of the pipe and cast into the ground together with the casing pipe, a drain material reel is installed on the deck of the casting vessel, and the drain material unwound from the reel is used as a leader. Characterized in that it is wound around a reel on the upper part of the boat and then drawn into a casing pipe.

[0006]

Embodiments of the present invention will be described below with reference to an embodiment of a drain casting boat according to the present invention.

<a> Reader. In the drain casting ship of the present invention, a leader 1 for driving a drain material is installed on the ship. A casing pipe 2 is attached to the reader 1 so as to be vertically movable. A pulling wire is attached to the upper end of the casing pipe 2 from above, and a pushing wire is attached from below. By winding by the winch of each wire, the casing pipe 2 can be moved up and down. This casing pipe 2
The drain material 3 is fixed to the lower end of the casing, and the casing pipe 2 is cast and the drain material 3 is cast on the water bottom.

<B> Installation of drain material 3 In a drain casting vessel of the type described above, the drain reel 31 is installed on the deck of the casting vessel. That is, the drain reel 31 is installed on a stable deck instead of being lifted and placed above the high and unstable reader 1.

<C> Turning tower. The drain material 3 unwound from the drain reel 31 can be directly drawn out to the upper part of the reader 1. However, the supply length of the drain material 3 is determined by the diameter of the drain reel 31, so if one drain material is consumed, it must be connected to the drain material 3 of the next reel 31. The supply of the drain material 3 must be stopped.

Therefore, a vertically long hollow case is provided as a folding tower 4 near the drain reel 31 in order to increase the connection time by reciprocating the drain material 3 vertically. The elevating reel 41 which rises and falls is stored inside the tower, and the elevating reel 41 is hung from the upper end of the tower 4 and installed so as to be able to reciprocate up and down. Then, the drain material 3 unwound from the drain reel 31 is wound around the elevating reel 41 and reciprocated vertically in the folding tower 4. The lower end of the drain material 3 is pulled out from the lower part of the turning tower 4. Therefore, even if the supply of the drain material 3 from the drain reel 31 side is stopped, by gradually lowering the elevating reel 41,
The drain material 3 can be supplied to the next step at the same speed within a certain time (time until the lifting reel 41 reaches the lower end).

<D> Drawer tower 5. As described above, the leader 1 is installed on the deck of the ship.
Attach the drawer tower 5 at a position adjacent to. An upper end reel 51 is attached to the upper end of the drawer tower 5,
The drain material 3 is always folded back by the upper end reel 51 and drawn downward. The drawer tower 5 is a hollow vertically long tower, but only one surface on the casing pipe 2 side is opened. A flexible split lid 52 composed of, for example, two rubber plates is attached to the release surface over the entire length.

<E> Casing pipe 2 of drain material 3
To supply. At the upper end of the casing pipe 2, two drawer reels 2 are provided.
1, 22 are attached. These two drawer reels 21 and 22 descend together with the casing pipe 2. Then, the drain material 3 returned from the upper reel 51 of the drawer tower 5 is guided from the upper portion of the casing pipe 2 to the inside. The drain material 3 in the drawer tower 5 is pushed out of the flexible split lid 52 to be exposed to the outside, guided by the drawer reel 22 at the upper end of the casing pipe 2, and drawn into the pipe 2.

<F> Pushing mechanism. Pressing of the flexible divided lid 52 is performed by dividing the divided lid 52 with the drain material 3 and the reel 2 so as to be easily understood in FIGS.
The state of pressing with 1 is described. However, in practice, the division of the division lid 52 is performed by the pressing roller 23 attached to the upper end of the casing pipe 2. (FIG. 5) These are rollers that are horizontally arranged rotatably so as to surround the top and bottom of the drawer reel 21 on the drawer tower 5 side.
This roller is rotatably attached to the upper end of the casing pipe 2. Therefore, the divided lid 52 is pushed to both sides by the pushing roller 23 disposed around the drawer reel 21, and the drain material 3 is pulled out from the space between the divided lids 52 in a state where the shape is maintained, and is put into the casing pipe 2. be introduced.

In addition to the embodiment shown in FIG. 5, it is also possible to adopt a configuration in which, for example, a boat-shaped guide member is attached to the periphery of the reel 21 in the vertical direction, and the division lid 52 is pushed open by the guide member.

<G> Arrangement of the drain material 3 The drain material 3 pulled out from the lower part of the folding tower 4 passes through the reel 42 at the lower end of the folding tower 4 and is pulled out of the drawing tower 5.
Pull in. Upper reel 5 at the upper end of drawer tower 5
1 and drain material 3 raised inside drawer tower 5
Is wound around the upper end reel 51 and folded downward.
The end of the folded drain material 3 is drawn into the casing pipe 2 from the upper end of the adjacent casing pipe 2 with the split lid 52 of the drawer tower 5 pressed down. The leading end of the drain material 3 having passed through this pipe is fixed to the lower end of the casing pipe 2. At the time of fixing, as shown in FIG. 6, a lid 2 that opens and closes the middle of the drain material 3 pushed out from the tip extra
3 is pressed and bent by closing, and is completely folded and fixed in the process of being pushed into the ground.

<H> Casting step. The step of driving the drain member 3 fixed to the tip of the casing pipe 2 into the water bottom by the above configuration will be described. The casing pipe 2 lifted to the uppermost part is driven into the water bottom by the downward force of the pushing wire and its own weight. In this step, the casing pipe 2 gradually descends.

On the other hand, the upper reel 51 installed on the upper end of the drawer tower 5 does not descend. for that reason,
The drain material 3 is drawn into the casing pipe 2 while pushing down the split lid 52 in accordance with the lowering of the upper end of the casing pipe 2, but the position where the split lid 52 is pushed down moves downward with the lowering of the upper end of the casing pipe 2. I will do it. For this reason, the drain material 3 has almost no portion exposed to the outside, and is stored in the casing pipe 2 directly from the drawer tower 5 and is not affected by external wind and rain.
As described above, if it is difficult to actually push the split lid 52 with the drain material 3 itself, as described above, the split lid 52 is attached to the pushing roller 23 attached to the upper end of the casing pipe 2 or to the reel. It is also possible to adopt a configuration such as pushing apart by a hull-shaped guide.

The drain member 3 fixed to the lower end of the casing pipe 2 is driven into the ground. After the casting is performed to a predetermined depth, the casing pipe 2 is pulled up. In this case, the cylinder 24 is projected from the end of the casing pipe 2 in accordance with the lifting distance so that the drain material 3 is not lifted at the same time, and the drain material 3 is pressed by the cylinder 24 for a predetermined distance. Drain material 3
When the frictional resistance of the cylinder becomes sufficient,
And collect it.

<Re> Connection of drain material 3 Since the drain material 3 is unwound from the drain reel 31 in parallel with the driving of the drain material 3, when it reaches the limit, it is necessary to connect to a new drain material 3. Until then, the drain material 3 has reciprocated extra in the folding tower 4. However, at the same time as stopping the drawing from the drain reel 31, the lifting reel 41 suspended on the upper end of the folding tower 4.
Is gradually lowered. Then, the drain material 3 can be supplied to the next process at the same speed within a certain time (time until the lifting reel 41 reaches the lower end), and it is not necessary to stop the driving. In this manner, the ground material can be improved by continuously driving the drain material 3 into the underwater ground.

[0020]

According to the present invention, the following effects can be obtained. <A> A drain reel for supplying drain material can be arranged on a deck, pulled out from that position, and can be driven into the ground. Therefore, the heavy drain reel can be safely driven without any unstable and dangerous work of suspending the drain reel up to the upper portion of the high casing pipe. <B> The drain material wound up from the deck level to the upper portion of the casing pipe is inserted from the upper end of the casing pipe almost without being exposed to the outside. Therefore, it is not affected by the weather. For this reason, there is no occurrence of an accident that the device bends on the way and is damaged by hitting the equipment or that the oil is attached and the water absorption performance is reduced. <C> When there is room, the drain material is reciprocated extra inside the folding tower, and when stopping the drawing, the lifting reel suspended at the upper end of the folding tower is gradually lowered. Then, the drain material can be supplied to the next step at the same speed within a certain time (time until the lifting reel reaches the lower end). Therefore, also in the time of the drain material connection step, there is no need to stop the supply of the drain material to the casing pipe, so there is no need to stop the driving operation.
