Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a partition block, a block structure using this block, and a method for constructing a simple breakwater and a quay wall construction method using the same.

[Prior art and its problems] (1) Construction of seawalls and breakwaters is being carried out to protect the banks of rivers and oceans from erosion by water currents and waves. In these construction works, after constructing the shore foundation work, anchorage work, or breakwater, foot protection work and wave dissipation work using blocks etc. are constructed adjacently. This conventional construction method not only takes a long time to complete, but also costs a lot of money.

(2) Also, as the block, a strangely shaped block such as a tetrapod is usually used. Irregular blocks are
They are piled up in multiple layers or in random piles in the construction areas of foot protection works and wave dissipation works.

However, conventionally used irregularly shaped blocks have the following problems. In other words, it is difficult to stack irregularly shaped blocks in a stable and orderly manner due to their structure.In other words, irregularly shaped blocks are manufactured on the basis of random stacking, so they are not equipped with connection and fixing means, and it is difficult to secure the blocks together when stacked. is not enough. Furthermore, the gaps between each block are also irregular, and the wave-damping effect is not uniform. Therefore, during long-term use, individual blocks often move due to the impact of water currents and waves, and uneven scour occurs, causing them to collapse, making it impossible to build structures such as platforms on top.

In addition, the irregular and coarse irregularities of the irregularly shaped blocks detract from the scenery, especially in tourist areas.

Furthermore, after construction, fish tend to gather near the irregularly shaped blocks, making them a great fishing spot, but the unstable footing causes many accidents such as anglers falling and falling.

[Purpose of the invention] The objects of the present invention are as follows.

(a) In the construction of seawalls and breakwaters, instead of constructing foot protection works and wave dissipation works using blocks etc. separately after constructing the foundation work and breakwater, To enable simultaneous construction to shorten the construction period and reduce costs.

(b) To be able to assemble blocks orderly and firmly vertically, front to rear, left to right, and to be able to withstand long-term use.

(C) It should be possible to construct a platform or the like on the upper part so as not to damage the scenery, especially in tourist areas, and also to prevent accidents such as anglers falling or falling.

[Structure of the Invention] The structure of the invention requested to solve the above problems and achieve the purpose is as follows.

The first invention is to extend the upper wall body and the lower wall body from the side wall body so that the cross-sectional shape is “C”.
An opening is formed on the opposite side of the side wall, a support is provided between the upper wall and the lower wall, and an insertion hole is provided in the upper wall and the lower wall to allow the shaft to pass through. This is a partition block provided with a partition block.

The upper wall body and the lower wall body may have, for example, a prismatic shape or a flat plate shape. It is preferable to provide fitting parts on the upper surface of the upper wall body and the lower surface of the lower wall body so as not to shift when stacking them, and on the sides of the upper wall body and the lower wall body, as necessary. A groove portion is provided that becomes a water passage portion when other blocks are joined.

The pillars are made of something that can withstand the load of other blocks or structures stacked on top, such as concrete filled with reinforcing bars, or concrete filled with waste tires, whose reuse has been researched in many ways in recent years. It is used after it has been solidified.

The shape of the support portion can be, for example, a curved shape as shown in the embodiment, or a straight shape.

A second invention is the partition block according to the first invention; an upper wall body and a lower wall body are connected by a support, an opening is provided around the periphery, and a shaft can be passed through the upper wall body and the lower wall body. A block body is provided with an insertion hole and has substantially the same external dimensions as the partition block, and the partition block according to the first invention is mounted on the mounting substrate in the same direction in the lateral and height directions. A wall is formed by side wall bodies arranged in several rows as appropriate, and on the opening side of the block, a plurality of block bodies are placed with the opening adjacent to the opening to form a substantially parallelepiped block group. A block structure is formed in which a top plate part is provided on the upper part of the block group, and each block, the mounting board, and the top plate part are integrally connected by a connecting shaft passing through the insertion hole of each block. It is.

As mentioned above, the wall of a block structure is formed by side walls, but block structures identical to the block structure are arranged symmetrically on the outside of the wall so that the side walls are back to back. Alternatively, a single partition block can be provided so that the side walls are back to back.

Partition blocks and block bodies are connected in the height direction by installing connectors such as concrete columns or long bolts in the insertion holes, but connectors are provided at appropriate locations to connect in the length and width directions. That is optional.

The mounting substrate is a plate-shaped body having sufficient strength, and is made of concrete with reinforcing steel inside, for example.

When the above-described partition block and block body are provided with a fitting portion, a fitting portion that is compatible with the partition block and the block body is provided on the upper surface of the mounting substrate as necessary. In this case, the shape of the fitting part is, for example, a protrusion, a protrusion, a fitting groove, etc., and corresponds to the fitting part of the abutting block.

The structure of the top plate is, for example, a structure in which a plate-shaped top plate is placed over the top of a block, or a structure in which the top plate is constructed by pouring concrete. Note that it is optional to provide connection means in each of the length direction and width direction on the mounting substrate and the top plate.

According to this block structure, it is possible to separate the inside and outside of the construction area, for example, the inland sea side and the open sea side in the construction of a breakwater. Furthermore, when used as a seawall, the bank side and extension side can be sealed and separated, eliminating bank erosion, which has the advantage of simplifying foundation work and anti-slip work.

The third invention is: (1) constructing rubble at the construction site of the breakwater; (2) laying a tire mat formed by connecting waste tires on top of the rubble; (3) laying the second invention on the tire mat. This is a simple breakwater construction method in which the block structure according to the above is constructed by arranging the side walls of the partition blocks so as to serve as partition walls between the inland sea side and the open sea side.

The fourth invention is: (1) constructing rubble at the construction site of the quay (2) laying a tire mat formed by connecting waste tires on the rubble; (3) placing partition blocks on the tire mat. Constructing the block structure according to the second invention with the side wall body facing the shore and slightly away from the shore (4) After filling the gap between the shore and the block structure with backfilling stone and installing shoulder stops. This is a quay wall construction method that involves more than just construction.

It should be noted that a road surface 106 is constructed on top of the top plate 3, and the details thereof have already been explained in FIG. 6, so a description thereof will be omitted.

I would like to explain about tire mats and rubble bales here. FIG. 9 is a plan view showing a portion of the tire mat 102. FIG. An arbitrary number of tires 80 are inserted and connected vertically and horizontally by reinforcing bars 81, which are small members, and wheel mounting holes 82 of the tires 80 and gaps 83 between the tires are sealed with a sealing body 84 made by cutting old tires and developing them. There is. This prevents the upper structure from sinking.

FIG. 10 is an explanatory diagram of a rubble bale, and FIG. 11 is an explanatory diagram showing a developed state of a tire sheet constituting the rubble bale. The rubble bale 103 is made by wrapping rubble (not shown) in a tire sheet 90. The tire sheet 90 is formed into a bag shape by arbitrarily connecting waste tire pieces separated into a tread portion 91 and a sidewall portion 92 with bolts and nuts. The waste tires used are preferably steel belt radial tires in which a steel belt is embedded in the tread part from the viewpoint of tensile strength. FIG. 12 is an explanatory diagram of the quay wall construction method according to the fourth invention. The construction method is as follows.

First, rubble 101 is constructed so as to slightly raise the block construction area on the thick side of the construction ground, and tire mat 102 is constructed on top of the rubble 101. Next, the block structure 100 is placed and constructed on the tire mat 102 with a slight distance from the shore. At this time, the side wall body 12 side of the partition block 1 is made to face the shore. And the shore and block structure 10
0 is filled with grouting stone 107, and shoulder stop concrete 108 is constructed from the upper part of grouting stone 107 to the top plate 3 of block structure 100. This structure is Gurishite 107
The structure is substantially the same as that shown in FIG. 6 except for the upper part.

As a result, a quay is built on the shore side and is not eroded by waves or currents. Note that the length of the construction part is set as appropriate. Then, a required number of rubble bales 103 are placed on the oil side end edge of the tire mat 102 to prevent scouring.

Note that the present invention is not limited to the above embodiments,
Various modifications are possible within the scope of the claims.

[Effects of the Invention] The present invention has fewer of the above configurations, and has the following features: (a) il! When constructing a bank or breakwater, the foundation work or breakwater has a structure that has the effect of foot protection and wave dissipation as it is, so it is not necessary to construct foot protection or wave dissipation work separately after the foundation work or breakwater construction as in the past. There's no need to. Therefore, the construction can be completed in a short period of time and the construction cost can be reduced.

(b) Since the blocks can be assembled orderly and firmly in the vertical and horizontal directions, they can withstand long-term use. In addition, the gaps formed by the blocks are regular and even, so construction work can be carried out without waste, taking into account the impact pressure of waves and water currents.

(C) Since the upper part can be constructed flat and platforms etc. can be constructed, the scenery will not be spoiled even in tourist areas, and the footing will be stable, so accidents for anglers can be prevented. In addition, it is possible to dock ships alongside, and it can also be used as a promenade, loading dock, etc.
