Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a column for driving into the bottom of the water, which is driven into the bottom of the water and erected in the water.

BACKGROUND OF THE INVENTION There are various uses for props that are driven into the bottom of the water, particularly the seabed and erected underwater. One example is seaweed netting. In the case of struts for spreading seaweed netting, a large number of struts are driven into the seabed, and the seaweed net is pasted between these struts. Conventionally, when driving the nori netting posts,
They used a hammer and manually hammered it from the top of the pillar. This driving work was performed by a worker on board a ship, and therefore lacked stability and was extremely difficult. Further, even when the support pillars are housed, extraction work is difficult for the above-mentioned reasons. The pillar that solved these shortcomings was registered as a utility model.
It is disclosed in No. 1468654 (Utility Model Publication No. 57-19978). This support will be explained with reference to FIGS. 6 and 7. In the figure, reference numeral 61 denotes a support main body, which has a sharp tip 62, and a through hole 63 formed in the center along the longitudinal direction of the support main body 61. Reference numeral 64 indicates a plurality of projecting tubes that protrude in the radial direction from the support main body 61, and a plurality of projecting tubes are provided at arbitrary positions on the outer surface of the support main body 61. The through holes 65 provided in each of these protruding tubes 64 are inserted into the through holes 6 of the support main body 61.
It communicates with 3. These protruding pipes 64 may be molded integrally with the support main body 61, or may be molded separately and fixed by, for example, gluing or twisting. 66 is a blind plug that seals the upper end opening of the support main body 61, and 67 is a blind cap that seals the opening of the projecting tube 64. Further, 68 is a ship, a pressure pump 69 is installed on this ship, the tip of the suction hose 610 of this pressure pump 69 is put into the sea, and the discharge hose 610 is put into the sea.
11 is connected to any one of the plurality of protruding tubes 64. 612 is sea level, 613
614 is a seaweed net stretched between multiple pillars. In a conventional device with such a configuration, the discharge hose 61
1 to the protruding pipe 64, and pressurized water is supplied to the strut main body 61.
When injected into the interior, the pressurized water passes through the through hole 63 and is ejected from the opening at the tip 62. By this, the seabed 6
Since the support can be driven in while drilling a hole in 13, the support can be driven in easily. Furthermore, when pulling out the support column, the work of pulling it out is facilitated by injecting pressurized water.

[Problems with conventional technology]

However, the protruding pipe 64 provided on the support main body 61
Since it protrudes for a long time, the protruding tube 64 and the blind cap 67 are easily damaged during transport to a fishing ground or during work, and there is also a risk that the blind cap 67 may be removed and the powder may be lost. Also, when opening and closing the through hole 65, the blind cap 67
It is troublesome to attach and detach the discharge hose 611, and furthermore, when injecting pressurized water, it is difficult to attach the discharge hose 611 to the protruding pipe 64, which takes time. Furthermore, the protruding tube 64 becomes a nuisance, making it difficult to use the floating ring used to prevent shells and the like from adhering to the support main body 61.

[Purpose of invention]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a driving column that allows pressurized water to be easily injected into the column body even when the operator is in an unstable state, such as when working on a boat. Another purpose of the present invention is to prevent the prop from being damaged by minimizing protrusions on the outside of the prop body, and to prevent the use of floating rings to prevent shells from adhering to the prop body. To provide a driving support that does not cause damage.

[Structure of the idea]

The structure of the invention devised to achieve the above purpose is as follows. That is, the present invention is a driving column that is driven into the bottom of the water and is erected in the water, and the column is provided with a column body, and a through hole is formed along the longitudinal direction of the column body. The lower end is open, and one or more water passage recesses are formed at appropriate positions on the outer surface of the support main body, and a lid body is provided to cover the water passage recesses, and the lid body is provided with a lid body so as to cover the water passage grooves. An external opening for injecting pressurized water is provided between the lid body and the water passage recess, and in a normal state, the external opening provided in the lid body is closed from the inside, and pressurized water is injected from the external opening. When injecting, an elastic valve is provided which deforms to the water passage recess side by water pressure to allow water to pass through.Furthermore, the water passage recess is provided with an injection hole that communicates with the through hole, and the injection hole is provided with an injection hole that communicates with the through hole. The position of the hole is a support for underwater driving that does not prevent pressurized water from flowing into the through hole when the elastic valve is deformed. Function Normally, the elastic valve is tightly attached to the inside of the lid body to close the external opening from the inside, thereby preventing the inflow of seawater. When pressurized water is injected from the external opening, the water pressure deforms the recess toward the water passage recess, allowing water to flow through the hole, allowing pressurized water to be injected into the through hole. Therefore, when the injection nozzle of the discharge hose of the pressure pump is attached to the external opening and pressurized water is injected, the pressurized water released from the injection nozzle deforms the elastic valve toward the water passage recess due to water pressure, and the pressurized water passes through the water passage recess. ,
It is poured into the through hole from the injection hole. Pressurized water is then ejected from the opening at the tip to excavate the seabed, thereby driving the prop into the seabed. Since the external opening is thus closed from the inside by the elastic valve, there is no need to attach or remove a blind cap. In addition, since pressurized water can be injected at any time, it is easy to drive in and remove the support even when the boat is unstable.

In the figure, reference numeral 1 denotes a strut, and the tip 2 is formed into a sharp point. A through hole 3 is formed in the center of the support main body 1 along the longitudinal direction. One or more injection holes 15 are provided at any location on the outer surface of the support main body 1, and a water passage recess 16 that surrounds the support main body 1 and forms a step is provided around the injection hole 15. be. An elastic valve 17 that externally and closely contacts the support body 1 is fitted into the water passage recess 16 , and the elastic valve 17 is provided with an internal opening 17 a that communicates with the injection hole 15 . Furthermore, a lid body 18 that closely contacts the outer periphery of the support main body 1 around the injection hole 15 and covers the elastic valve 17 is provided.
The lid body 18 has an internal opening 17a.
An external opening 18a is provided at a position substantially opposite to. Note that the position of the external opening 18a does not necessarily have to be exactly opposite to the internal opening 17a, and may be offset as long as it does not communicate with the internal opening 17a. The diameter of the internal opening 17a is set to approximately match the diameter of the injection hole 15. Reference numeral 6 is a blind plug that seals the upper end opening of the support main body 1. Function The function of this embodiment will be explained. When injecting pressurized water, as shown in Figures 2 and 3, a pressure pump (not shown) is installed on the ship, the tip of the suction hose of this pressure pump is put into the sea, and the injection nozzle 19 of the discharge hose is inserted. It is attached to the entrance of the external opening 18a and pressurized water is injected. The pressurized water discharged from the injection nozzle 19 in the direction of arrow A is caused by the water pressure to flow through the elastic valve 17.
Push out the elastic valve 1 toward the center of the strut body 1.
A water passage 16a is formed around the entire circumference between the cap 7 and the lid 18. Pressurized water discharged from the injection nozzle 19 passes through this water passage 16a, and the pressurized water flows into the column 1 through the internal opening 17a of the elastic valve 17 provided at a position substantially opposite to the external opening 18a and the injection hole 15 of the column 1 that communicates with the internal opening 17a. It is poured into the through hole 3 (in the direction of arrow B).
Pressurized water is then ejected from the opening at the tip 2 to excavate the seabed, thereby driving the prop into the seabed. In addition, when pressurized water is injected from other injection holes or other than during injection, water pressure is applied to the elastic valve 17 from the through hole 3 of the support 1 through the injection hole 15, as shown in FIGS. 4 and 5. (in the direction of arrow C), the internal opening 17a is also pressed against the lid 18, and the internal opening 17a is closed, thereby preventing water leakage from the support main body 1. It should be noted that the present invention is not limited to the illustrated embodiment, and many modifications can be made within the scope of the claims of the utility model registration.

[Effect of the idea]

The driving post according to the present invention has the above configuration,
It has the following effects. (1) Pressurized water can be injected into the column body simply by inserting the injection nozzle of the discharge hose into the external opening provided in the lid, making it easy to inject pressurized water.
Therefore, even when the worker is in an unstable state, such as when working on a boat, it is easy to drive in and remove the support. (2) A lid is installed on the outside of the pillar body.
The outer diameter of the support is only increased by the thickness of the lid. Therefore, there is no concern that the floating ring for preventing shells and the like from adhering to the support will get caught on the lid, and there will be little difficulty in using the floating ring. Furthermore, since there are no protrusions that could cause damage, damage to the support can be prevented, and the protrusions do not get in the way when storing, making it convenient. (3) If multiple injection holes are provided in the main body of the column,
Since the injection hole can be arbitrarily selected at a position that is convenient for work depending on the state of the seabed or the tidal level, there is no need to consider the ebb and flow of the tide, and work efficiency can be greatly improved. (4) A lid is installed in the water passage recess in the main body of the column. Therefore, it is possible to reinforce the weakening of the mechanical strength of the column main body due to the provision of the water passage recess and the injection hole in the column main body. (5) The elastic valve deforms only when pressurized water is injected, and under normal conditions it tightly fits inside the lid to prevent seawater from entering from the outside. Therefore, it is possible to prevent shells and the like from adhering and growing inside the through hole inside the support main body.
