Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a leakage prevention wall for preventing waste from leaking in a structure that surrounds an oceanic lake or marsh and buries waste inside the structure. .

[Conventional technology]

Structures that enclose the ocean and bury waste inside are strictly regulated to prevent waste from leaking, and in addition to leakage, there is also a serious risk of a decline in the strength of the parts due to corrosion of the parts used in the ocean. This has become a serious problem.

There have been a wide variety of wall bodies to solve this problem, and in particular, there are walls using gravity type caissons, walls using steel pipe piles, and walls using steel sheet piles.

Among these, walls made of gravity-type caissons and walls made of steel sheet piles are often used.

Here, these two types of wall bodies will be explained as prior art.

FIG. 6 is a sectional view showing the first conventional example, and FIG. 7 is a front view of the first conventional example.

In the case of the gravity-type caisson wall shown in the figure, it is necessary to improve the ground 1 where the work is being carried out, especially if the work is on soft ground made of sludge or sand, by constructing rubble or rubble mounds 2 on top of the ground 1. This prevents uneven settlement.

Reference numeral 3 designates a caisson, which is hollow and shaped like a reinforced concrete, and is manufactured at a work base on land, launched, towed, filled with water at the construction site, and sunk above the rubble mound 2.

After that, concrete or gravel is placed inside caisson 3.
Fill it with earth and sand.

In addition, in order to ensure that the installation does not interfere with the work and filling work, the caisson 3 is often of a predetermined standard size that can be adapted to the workability, and the caisson 3 is installed later.
To prevent gaps from forming between the caisson 3 and the rubble mound 2, or to prevent waste material from leaking outside from the rubble mound 2, etc., install a sheet 4 to prevent movement on the back of the caisson 3 and the rubble mound 2. use

FIG. 8 is a perspective view showing a second conventional example.

In the figure, 5 is a steel sheet pile, which is often used because it is lightweight and has great durability and strength.If iron is used in seawater, it will cause electrolytic corrosion and rust, so leave some rust allowance in advance or apply paint. and prevent it.

Generally, the wall of the steel sheet pile 5 is made by cutting the roots deeply to the full extent of the site, and then pouring the support layer 1 to form an integral wall.

[Problem that the invention seeks to solve]

The problem with the above-mentioned conventional technique is that the gravity-type caisson wall of the first conventional example is not stable and sometimes requires ground improvement.

A land-based work base for making caissons is also required;
There is a problem in that large-scale construction work is required, which involves launching the vessel, towing it, and submerging it at the construction site.

In this case, great care must be taken when towing the caisson, and when sinking the caisson, there is a problem in that the hollow part of the caisson must be filled with concrete, gravel, earth, etc.

Furthermore, there would be no problem if the wall was made of a normal gravity-type caisson, but since it is a retaining wall structure that buries waste at a waste disposal site, it is necessary to use suction prevention measures to prevent waste from leaking. It must be laid inside the sheet e.

Therefore, there is a problem in that it is a large-scale construction work and requires a high construction cost.

In the steel sheet pile wall of the second conventional example, all the steel sheet piles must be continuously driven up to the support layer, and backing work is required.

Trenches and steel sheet piles are made of steel, etc., and are easily corroded in seawater due to electrolytic corrosion.In order to prevent this, steel or iron mixed with a small amount of copper, chromium, and nickel is used, but the material cost is high. There is a problem.

Furthermore, there are methods to prevent these, such as by applying paint, but this is not a permanent method, and the problem of preventing waste leakage at waste disposal sites, which is the issue of this issue, is that the prevention effect decreases over time. There is.

The present invention solves the above-mentioned problems by providing a permanent and inexpensive wall that can stand on its own.

[Means for solving problems]

In order to solve the above problems, the present invention makes the support piles self-supporting by driving them into the support ground at predetermined intervals, and each support pile is provided with a joint means.

This joint means is connected to both ends of the bulkhead panel whose cross-sectional shape is bent in an arch shape, and the shielding panels separately installed on the inner side of each bulkhead panel are connected to both sides of the support piles and tightly attached to both bulkhead panels. This feature is characterized in that the gap created at the joint between the support pile and the bulkhead panel is blocked, resulting in a watertight structure as a whole.

[Function] The present invention configured as described above is such that when the supporting piles provided with the joint means are driven into the supporting ground at predetermined intervals, errors occur in the driving angle positions of the supporting piles in the longitudinal and lateral directions. Difficult to connect bulkhead panels.

In order to compensate for this, it is possible to adjust the errors in the longitudinal and lateral directions and connect the parts using a joint means.

Furthermore, since the partition panel has an arched cross-sectional shape in response to pressure from the inside of the wall, it has pressure resistance and stability.

The barrier panel prevents waste from leaking through the gap between the support pile and the partition wall panels connected to both sides of the support pile, and the actions of these parts create a durable wall that is integrated.

〔Example〕

FIG. 1 is a perspective view showing one embodiment, and FIG. 2 is a perspective view showing main parts of FIG. 1.

In the figure, reference numeral 6 indicates support piles, which are driven into the supporting ground at predetermined intervals so as to stand on their own.

A half-split fixing member 7 shaped to abut on the outer surface of the support pile 6 is provided, and connecting portions 8 are formed at both ends of the fixing member 7, and support is provided in line with one of the connecting portions 8. A piece 9 is provided protrudingly, a guide plate 10 is installed between the connecting part 8 and the support piece 9, and a locking piece 11 is movably fitted onto the guide plate 10 to form a joint means 12.

The coupling means 12 are connected in pairs with facing each other and fixed to the support pile. Next, from the sectional view of FIG. 3, reference numeral 13 is a partition wall panel, the iron plate 14 which is a rigid body is used as a stress material, the rubber plate 15 which is an elastic body is used as a covering material, and the iron plate 14 is placed between the rubber plates 15. By burying it, it not only increases its strength but also provides corrosion and rust protection.

Its shape is preformed to a size that matches the predetermined spacing of each support pile 6.

The upper membrane partition panel 13 has a cross-sectional shape bent in an arch shape from a direction of pressure to a direction of decrease due to a pressure difference between earth pressure, etc. inside the disposal site, and water pressure, wave pressure, etc. outside. Dimensional adjustment plates 16 are provided in the longitudinal direction at both ends of the partition panel 13, and the partition panel 13 is fixed to the locking piece 11 of the joint means 12 via the size adjusting plate 16, and the position when the locking piece 11 is subsequently fixed. to fix it to the guide plate 10.

Reference numeral 17 denotes a shielding panel, and as shown in the cross-sectional views and partially cutaway views of FIGS. is buried in between.

Both ends of this barrier panel 17 are brought into close contact with both ends of the partition wall panels 130 from the inside of the disposal site, and the supporting piles 6 and partition wall panels 13
The gaps that occur in the connecting parts are blocked and the entire structure is watertight.

Further, the shielding panel 17 has a bellows structure with ample space.

The operation of the embodiment configured as above will be explained.

When the support pile 6 provided with the joint means 12 is driven into the support ground, errors occur in the driving angle of the support pile 6 in the longitudinal and lateral directions.

Therefore, as shown in the sectional view of the main part in FIG. 5, in order to compensate for these errors, the locking piece 11 is movably fitted into the guide plate 10 provided on the joint means 12, so that the locking piece 11 can be moved back and forth. It can be moved and fixed after adjusting the front and back errors.

In addition, the lateral adjustment can be made by moving the dimension adjustment plates 16 provided at both ends of the partition wall panel 13 and fixing them to the locking pieces 11, which facilitates the work of connecting the partition wall panels 13. The partition wall panel 13 connected to the joint means 12 has a cross-sectional shape bent in an arch shape against pressure from the inside of the wall body, so that pressure resistance can be achieved.

Furthermore, by bringing both ends of the shielding panel 1T into close contact with both ends of both bulkhead panels 13 from the inside, a gap that occurs at the connecting portion between support pile 6 and both bulkhead panels 13 can be blocked, and a watertight structure can be achieved as a whole. Also, since it has a bellows structure, it can withstand tension accompanied by compression.

〔Effect of the invention〕

As explained in detail above, in the wall according to the present invention, supporting piles are driven into the supporting layer at predetermined intervals, and the number of supporting piles used in the usage range is small, and the supporting piles are provided with a joint means having a locking piece. This has the effect of making it possible to adjust the displacement of the driven support piles that occurs during construction, making the work easier.

In addition, the bulkhead panels and shielding panels between the support piles are coated with rubber plates, so even if waste such as gravel or plastic hits directly when the waste is thrown in, the buffering effect will buffer it and further. Since a rigid steel plate is embedded, it can be reinforced against tearing of the rubber plate, preventing leakage at the waste disposal site, and exhibiting long-term stability and durability against seawater. In addition, the partition panel whose cross-sectional shapes are connected in an arch shape has the effect of exhibiting pressure resistance against pressure from the inside.

The shielding panels that cover the support piles and the bulkhead panels on both sides are made of rubber plates made of elastic material with wire mesh, which is a non-directional reinforcing material, buried in the middle, so they are protected against direct hits from stones, etc. It can attenuate impact force and improve durability against tearing.

1. The above-mentioned shielding panel is bent into a bellows structure, which allows it to withstand lateral tensile force.
In addition to blocking gaps, it is possible to connect support piles and bulkhead panels.

The present invention, which has these characteristics, can be expected to have the effect of preventing waste from leaking at a waste disposal site, being able to be constructed in a short period of time, reducing costs, and providing an inexpensive and excellent wall body.
