Description

[Detailed description of the invention] [Industrial application field] This invention is used, for example, to drive glass fiber-reinforced plastic supports into the seabed, which are used when cultivating seaweed, fish, and seaweed. This invention relates to an improved structure of a position fixing tool for keeping the depth of penetration constant and maintaining and stabilizing the position after being driven into the ground.

[Conventional technology] Conventionally, when building this type of aquaculture support, the depth to which it would be driven into the ground was determined entirely by intuition.
If the ground is soft, such as sandy soil, it may be difficult to determine the depth at which it will be driven into the ground, leading to over-driving. Furthermore, the driven state will not be fixed and will be unstable, causing the support to sink or fall. There may be times when the situation goes up or goes up again.

For this reason, some devices have been devised to stabilize the front support by wrapping a rope around the support or attaching protrusions, but these methods require time and effort to wrap the rope or attach protrusions. Moreover, when storing the prop, the rope and protrusions were bulky and difficult to handle.

Therefore, the applicant proposed that the lower half of a flat plate made of a flexible material, which has a width equal to the length that goes around the lower outer circumferential surface of the support column and a vertical width equal to the required length, can be opened at any angle by vertically cutting the lower half of the flat plate made of a flexible material. He devised a position fixing device in which a large number of hanging pieces were formed, and a hook piece and an engagement hole for locking the hook piece were provided at the upper end of the flat plate, and he filed an application earlier in Utility Model Application No. 1983-7810. . Attach this positioning fixture to the bottom of the column,
If you stand this prop upright in the sea and hammer the top,
When the position fixing device is in contact with the ground and driving is continued, each hanging piece opens, and by coming into contact with the ground in the open angle state, each hanging piece functions as a stopper. In this case, each hanging piece curves upward in the ground as it is driven further and functions as a resistor. However, depending on the geology, each hanging piece has a high rigidity, so it cannot be opened sufficiently when driving the support. Even if the rigidity was increased, it was sometimes difficult for each hanging piece to open properly even when the support was driven into soft ground.

[Purpose of the invention] The present invention is to provide a position where the intermediate part can be installed in a state where it is reliably expanded wider than the outside diameter of the support, and the bulge does not disappear even when the support is driven in, and functions as a resistor. It provides a fixing device.

[Structure of the invention] The central part of a flat plate made of a flexible material has a width equal to the length that goes around the lower outer circumferential surface of the support for aquaculture and a length equal to the required length, and the central part of the flat plate is made of a flexible material. A large number of strip-like pieces are formed by cutting and bending, and a hook piece is formed at one end of the left and right sides at the upper and lower ends of the flat plate, respectively, and an engaging hole for locking the hook piece is provided at the other end. Configure.

[Function] Attach and fix either the upper end or the lower end of the position fixing device to the aquaculture support by locking the hook in the engagement hole, and then bring the other end close to the end and attach each strip. By bending or bending each part outward and locking the hook piece on the other end into the engagement hole, a protruding part with a diameter larger than the outer diameter of the column is formed, and this column is placed upright in the sea. When the strips protruding from the outside of the positioning fixture touch the ground, they function as stoppers and securely fix the column. In addition, if the place where the pillar is driven is soft ground, by driving it further, each strip part will be buried in the ground with protruding parts and function as a resistor, and it will involve mud, causing the pillar to sink, fall down, or fall out. It can be stabilized so that it does not rise.

Furthermore, if either the upper end or the lower end of the positioning fixture is left free during storage, the positioning fixture will have a size close to the outside diameter of the column and will be in a state without any protruding parts, thereby increasing storage efficiency.

[Example] In the figure, reference numeral 1 denotes a flexible flat plate such as a rubber plate, which has a horizontal width that approximately goes around the lower outer peripheral surface of the aquaculture support column 2, and a required vertical width. Cutting lines 3 are provided at equal intervals in the longitudinal direction in the central portion of the belt 1 to form a large number of bendable band-like pieces 4.

Projecting pieces 5, 5' are provided on the upper and lower ends of the flat plate 1, respectively, at the left and right side ends, and hook pieces 6a, 6b are provided on the inner surface of each projecting piece 5 on one side, and each protruding piece 5' on the other side. have engaging holes 7a and 7 for locking hook pieces 6a and 6b, respectively.
b, and further extend the knob pieces 8a, 8b to the tip of each protruding piece 5', so that the respective knob pieces 8a, 8b
An uneven anti-slip layer 9 is formed on the side surface.
Further, on the inner surface of the upper and lower ends of the flat plate 1, a large number of horizontal protrusions are arranged in a row to form a non-slip portion 10.

Next, to explain the use of the position fixing device of the present invention constructed in this way, the position fixing device A applies the flat plate 1 to the outer circumferential surface of the support column 2 at the position where it is driven into the ground. By pulling one of the knob pieces 8a (the upper end in FIG. 3), the hook piece 6a is engaged with the engagement hole 7a and fixed in position. Next, the other (third
(lower end in the figure) is pulled upward to bring it close to the one side, and in that state, the hook piece 6b is locked and fixed in the engagement hole 7b, and each strip part 4 is moved outward as shown in FIG. Bend it so that it sticks out.

Then, the aquaculture support 2 with the position fixing device A attached thereto is stood upright in the sea, and the upper end is hammered into the ground E. As this driving progresses, the lower side of each strip portion 4 bent outward touches the ground, and the fifth
It functions as a stopper as shown in the figure.

In addition, if the place where the pillar is driven is on soft ground,
If the pillar 2 is driven into the ground from the state shown in Fig. 5, each strip 4 becomes a resistor in the ground as shown in Fig. 6, and the resistance force causes the pillar 2 to It can be stabilized and firmly fixed without sinking, falling over, or slipping out.

In addition, when attaching and fixing the position fixing device A to the pillar 2, if the driving place is soft or hard ground, install it in a state where each strip part 4 is inflated to a curved extent as shown in Fig. 7, and then drive it. If the ground is soft or soft, better resistance can be exerted by mounting each strip 4 so that it protrudes enough to bend as shown in FIG. 8.

In the case shown in FIG. 9, the position fixing device for the aquaculture support is formed into a substantially parallelogram by tilting both left and right ends of the flat plate 1 in the same direction, and each separation line 3 is set at the left and right ends. Each strip portion 4 is formed in an inclined shape by being provided parallel to the inclined side of the strip portion 4 . Since each strip portion 4 formed in an inclined shape has a twist when bent outward, it becomes easy for mud to enter the inside, and the projecting state is maintained by being clogged with mud. It exhibits torsional rigidity even in a state where it is not clogged, making it possible to increase resistance during use.

Furthermore, as shown in FIG. 10, when ribs 11 are provided protrudingly on the surface of each strip portion 4, the elasticity and shape retention of each strip portion 4 are enhanced by these ribs 11. It can exhibit strong resistance when used.

Note that a plurality of position fixing tools A can be installed in multiple stages and used.

[Effect of the invention] As described above, the aquaculture support position fixing device of the present invention is attached to a predetermined position at the bottom of the support, and the support can be hammered in exactly the same way as normal hammering. Then, as the driving progresses, each protruding strip portion of the position fixing tool can function as a grounding stopper to fix the support column. In addition, if the driving location is soft ground, the position fixing device is driven until it is buried in the ground, and each bent strip part functions as an underground resistor to prevent subsidence, lodging, and uplift. It is possible to stabilize the pillar without causing it to rise.
