Abstract

The present invention comprises a hollow block by forming a hollow block at the bottom of a slope of the sandstone structure connected to the seabed or riverbed such as a sandstone breakwater, a lake bank, a river embankment, and the like. By blocking the invention is to maintain the solid structure of the dead stone structure for a long time.

Description

The lower column department inclined plane protection structures of riverbed construction}

The present invention is a invention for the structure of the bottom end of the protection surface of the slope of the bottom of the seabed or the bottom of the sandstone structure in contact with the seawater or river water, such as breakwater, lake banks, river banks, etc. When the stone on the lower part of the slope of the sandstone structure is scoured or lost due to the blue or flowing water, the displacement of the stone such as the scour of the sandstone and sinking collapse of the body due to the loss occurs. Displacement occurs regardless of the geology of the ground, so that the upper structure of the sandstone structure has a huge adverse effect on safety.

As described above, the inclined surface 2 of the stone structure 1 by the blue water pressure, wave pressure, or hydraulic pressure of the stone structure continues to crush and lose the stone over time from the lower end portion, and gradually leads to the collapse of the structure. Although the protection of the lower end of the inclined surface is the most important basic construction due to the severe adverse effect on the safety of the stone structure, in order to save construction costs, the attached bottom of the lower surface 2a of the inclined surface of the stone structure 1 is generally attached as shown in FIG. Since the surface jaw 4 is formed with a predetermined width at a predetermined height position from the surface or the lower bed 3, the inclined surface of the dead stone structure 1 is covered with a covering stone 5 so that the dead stone oil chamber is not completely blocked. It is a situation that the lower end of the inclined surface of the stone structure structure (1) is required to be constructed in a structure of a more robust protective hole.

Figure 2 is a cross-sectional view showing the base of the inclined surface of the lower bed structure constructed in accordance with the present invention.

1. Stone structure 2. Slope 2a. Inclined surface 3. Seabed or riverbed

4. Surface jaw 5,5a. Cover Stone 10. Bottom Tip Protector

11. Farmland 11a. Soft bed 12,12a. Hollow block 12b. Front wall

The present invention is an invention for the structure of the lower end of the protective hole to be constructed as a protective structure of a separate structure to protect the lower end of the inclined surface (2) of the stone structure (1) easy to be neglected construction during construction In constructing the structure of the lower end protection hole 10, a unit hollow block in which the bottom or the bottom is a solid body in the case of the hard soil 11, and in the case of the soft soil 11a, is laminated in a plurality of bodies. (A case of 11a)) 12 and 12a are stacked, and the left and right sides of the hollow blocks 12 stacked on top of the hollow blocks 12 and 12a are filled with the sandstone 13. The upper surface of the wall (only one side wall 14 is shown in Fig. 2) is formed into a concave upper surface 15 concaved to a predetermined depth, and the seating surface 13 is also filled in the concave upper surface 15 side. (13a) The sandstone structure (1) the covering laid on the inclined surface of the sandstone structure in the length direction. The blocking jaw body 16 is interposed between the front surface of the blocking jaw body 16 and the front wall 12b of the hollow block 12 via the covering stone 5a through the concrete blocking jaw body 16 through which the lower end side of the wall 5 is blocked. ) Is fixed to the lower end of the lower end of the structure of the riverbed structure to be fixed to the structure to be fixed in accordance with the present invention.

When the construction is made of the protection surface structure of the lower end of the inclined surface of the riverbed structure constructed in the present invention constituted as described above, the tip is made of concrete hollow blocks 12 and 12a, so that it is shielding the sandstone, Since the sandstones 13 are not lost even in running water, the structure is firmly maintained, and the coated stone 5 covering the inclined surface is also disposed on the hollow block 12 by the concrete blocking member 16 at the bottom of the covered stone 5 of the inclined surface 2. Since the shielding stone 5 is prevented from collapsing, there is an effect of providing a solid sandstone structure that does not naturally cause a serious problem caused by collapse of the structure by neglecting the conventional construction.

Claims (1)
