Abstract

PURPOSE:To form a structure which is strong for penetrating of water in the sea and large in solid properties by forming a block filled with building waste into an uneven shape engaged with each other and providing a hole capable of inserting reinforcing steel connected to an anchor to this block. CONSTITUTION:Building waste is filled into a pontoon made of reinforced concrete. The blocks 4, 5 filled with building waste are formed by applying topping concrete to the upper part thereof and settled into the bottom of the sea and accumulated. These blocks 4, 5 are formed into an uneven shapes 1, 3 engaged with each other. Holes 2 capable of inserting reinforcing steel connected to a temporary anchor are provided to the blocks 4, 5. As a result, it is possible to manufacture a structure which is strong against water penetration and large in solid properties even when many pieces of blocks 4, 5 are overlapped in the sea or connected in the horizontal direction and a building easy to construct and having various shapes.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to marine treatment technology for construction waste. In other words, it relates to a structure in which concrete blocks made of construction waste are piled up, and more specifically, it relates to a structure in which a reinforced concrete ark is filled with construction waste and a construction waste filling block with concrete topping is placed on top of the ark. It is something.

(Prior Art) Various studies have been conducted on the treatment of construction waste because the treatment methods are limited due to the coarseness of the waste, the scale of generation, and the large amount of waste. This is the current situation.

Conventional methods for disposing of construction waste include processing and processing for reuse, use as material for land development and landfill, and dumping in mountainous areas.

(Problem to be solved by the invention) As mentioned above, there is no definitive method for disposing of construction waste, and the conventional technology has its advantages and disadvantages, and the current situation is that the treatment itself is a problem. It is.

Even if it is recycled through processing, there are certain limits because it is waste, and there are also certain limits or restrictions when it comes to landfilling, creating artificial islands, or even dumping it on vacant land.

The treatment of construction waste is now a socially important issue, and the current situation is that there is a desire for the development of large-scale waste disposal means.

Therefore, the inventors of the present invention previously proposed a method for disposing of construction waste in Japanese Patent Application No. 193896/1996. When stacking a large number of construction waste filling blocks consisting of treated materials underwater or connecting them horizontally, if the external shape of the blocks is a cube or rectangular parallelepiped consisting of just a flat surface, the joint surface Since it is susceptible to water penetration, it is not possible to obtain a strong structure, and it also causes various inconveniences during construction, and also causes various inconveniences such as a simple structure and shape.

The present invention has been made in view of the above problems, and its purpose is to provide a structure that is resistant to water penetration even when a large number of the blocks described above are stacked underwater or connected horizontally, and is highly compact. To provide a block-laid structure for processing construction waste, from which a structure can be obtained, which is easy to construct, and can be constructed in various shapes.

(Means and effects for solving the problem) The present inventors
After conducting various studies in an attempt to solve the above problems, we found that the construction waste filling block described above has a concave and convex shape that fits into each other, and that the block has holes through which reinforcing bars to be connected to the anchor can be inserted. We focused on using a device with a

That is, the gist of the present invention is to provide a construction waste filling process consisting of a reinforced concrete ark filled with construction waste and topped with concrete.
In the block stack structure, which is built by sinking to the seabed,
This is a construction waste disposal block structure characterized by a combination of blocks that have concave and convex shapes that fit into each other and have holes through which reinforcing bars connected to temporary anchors are inserted.

The block in the present invention is filled with construction waste, and its manufacturing method is to fill a reinforced concrete ark with a predetermined shape with construction waste, and then top it with concrete. Since the purpose of the present invention is to dispose of construction waste at sea, it is desirable that the size of each block ranges from several hundred tons to several tons.

Next, regarding the shape of the block according to the present invention, the upper and lower surfaces are flat, and the side surfaces have an uneven shape that fits into each other. This makes the block structure and horizontal connections tighter, making the joint surfaces stronger. The shape of the unevenness may be either angular or arcuate. Further, the position of the uneven shape is not particularly limited, and there may be various configurations such as having concave portions or convex portions on four sides, having concave portions on one side and forming a convex portion on one side. The shape of this block as a whole may be either a square or a rectangle.

Next, it is preferable that this block is provided with holes in the upper and lower directions of the block, through which reinforcing bars (tension members) connected to temporary anchors embedded in the support layer under the seabed are inserted. As a result, the structure can be constructed by lowering the blocks to a predetermined position, and the block stack structure can be constructed in an orderly manner using the reinforcing bars connected to the anchors as guide rails. Furthermore, by applying tension by tightening the reinforcing bars connected to the anchors with bolts, etc., the rigidity and solidity of the structure will be improved, and watertightness will be ensured to prevent water from penetrating the joint surfaces.

Furthermore, when joining the blocks in the horizontal direction in the present invention, instead of simply fitting the uneven surfaces, it is also possible to grout the fitting surfaces with cement or resin, or use a joining mechanism using various joining fittings.

The block structure of the present invention can be used for constructing walls of various shapes, breakwaters, artificial islands, underwater waste dumps, and the like.

The present invention will be explained below based on examples.

(Example) FIG. 1 is a plan view of a construction waste filling block used in the present invention. In FIG. 1(a), 4 is a block having a recess 1 on its four sides, and 2 is a hole through which a reinforcing bar connected to an anchor is inserted.

Further, in FIG. 1(b), 5 is a block having a shape having convex portions 3 on four sides. And Fig. 1(a),(b)
') The upper and lower surfaces of both blocks are flat. Then the second
The figure shows the state in which the blocks 4.5 shown in (a) and (b) of Fig. 1 are connected and joined, and the block 4 and the block 5 are fitted together. It is. By stacking these connected blocks one above the other, a continuous wall of any height can be constructed. FIG. 3 is a three-dimensional perspective view of the block 5 shown in FIG. 2(b).

The block 6.7 shown in FIGS. 4(a) and 4(b) has a concave portion on one side and a convex portion on the other side, and FIG. 5 shows the block 6.7 shown in FIG. 4(a). , (b), the concave and convex portions of the block 6.7 are connected in a fitted state.

And Figure 1 (a), (b) and Figure 4 (a) (b)
By appropriately combining and connecting blocks of the shape of , it is possible to construct a structure as shown in 8 in Figure 6. You can also throw things in and cover the surface with blocks to create an artificial island.

(Effects of the Invention) According to the present invention, construction waste filling blocks can be constructed in an orderly manner using anchors as guide rails, and since uneven blocks are fitted and joined, many blocks can be stacked underwater or joined horizontally. It is resistant to water penetration and provides a highly solid structure. Since it is easy to construct and structures of various shapes can be obtained, it is extremely effective as a marine treatment technology for large-scale construction waste.
