Description

  The present invention relates to a structure of a breakwater such as a breakwater and a seawall constructed on a coast or a river revetment, and in particular, a see-through window is provided on the embankment wall, and the landscape of the sea or river can be viewed through the see-through window in normal times, and floods, storm surges The present invention relates to a see-through window structure of a levee equipped with a hard-strength transparent plate that can withstand external pressures such as wave pressure and water pressure applied to the levee in the event of a flood such as a tsunami.

  Conventionally, breakwaters and seawalls have been constructed on the coast as countermeasures against tsunamis and storm surges, and riverbanks have been constructed to protect people and houses on land from floods caused by precipitation. The embankment is generally made of reinforced concrete, but there are also revetments, etc., where the main body of the embankment is made of earth or stone.

  When a strong tsunami hit by an earthquake, such as the 2011 Tohoku earthquake that occurred in Japan, the tsunami not only overwhelmed the embankment and flooded the land, but also collapsed the embankment itself, causing enormous damage to people and homes. Damage will occur. In recent years, floods due to high waves and storm surges have frequently occurred due to large typhoons that are said to be caused by global warming.

  In addition, there are frequent situations such as flooding of rivers due to sudden torrential rains, also called bomb lows, and river flooding such as bank breaks. For this reason, with the aim of preserving the land from such floods, laws, rules and specifications related to the construction of embankments have been revised in the technical field of civil engineering, and improvements have been made with emphasis on safety and security. There is a current situation where large dikes are being constructed. However, such a huge embankment not only impairs the surrounding natural scenery, but also obstructs the view from the land side and obstructs the beautiful natural view of the sea and rivers in normal times.

  Therefore, for example, a polycarbonate plate, which is a main see-through plate, is superposed on a levee main body wall with a tempered glass plate and fitted in three layers at a predetermined interval and fixed in a window frame. A see-through structure in which a see-through window body with a protective material attached is incorporated in a dike body and fixed to a dike foundation or a see-through window body structure is incorporated in a wall of a dike (see Patent Document 1). For the purpose of placing the levee body wall structure in the notch of the raised embankment, openable and openable levee breast wall structure with an arc-shaped convex transparent panel arranged on a frame mainly composed of pipe columns and pipe cross beams ( Patent Document 2). A side wall of 10m or more along the coast and a building is built between the side walls at right angles to the coast and connected to the side wall, and the joint between the side wall and the building is sharp, and many side walls An opening is provided, and a waterproof door is arranged on the side wall ground, and the opening and the waterproof door on the side wall are mechanically or manually closed.When a tsunami occurs, the waterproof door is closed. Buildings for tsunami / flood countermeasures (see Patent Document 3), which are free to enter and exit from the waterproof door, are well-lighted from the side walls, and used as wind intakes, have been proposed.

  However, the see-through plates fitted in the window frame in the see-through type dike and the see-through structure of Patent Document 1 are arranged at a predetermined interval in the front-rear direction of the window frame, and the gap is in a hollow state. Yes. Further, since the window frame facing the sea is also arranged in a hollow frame in which a plurality of cross members are arranged, moisture accumulates in the cavity and the hollow portion, and there is a possibility that fogging occurs in the see-through plate. Further, there is a drawback that the visibility is blocked by arranging a plurality of cross members inside the shielding gate.

  The fluoroscopic panel disclosed in Patent Document 2 has a front panel and a back panel that are overlapped with each other. Therefore, the surface may be damaged when the back panel is moved left and right. There is a problem that operation check work is required, and a great deal of labor and labor is required.

  In view of the above-mentioned problems of the prior art, the present invention naturally has sufficient durability against water damage such as tsunami and storm surge, excellent perspective performance, can be easily installed and replaced, maintenance, etc. An object of the present invention is to provide an economical embankment see-through window structure that saves labor.

  For this reason, the see-through window structure of the embankment of the present invention is a see-through window structure of the embankment in which openings that penetrate both sides of the embankment wall are provided and a transparent plate is fitted into the openings to construct a see-through window. A transparent window comprising a pre-embedded window frame embedded in a dike wall, a fixed window frame that is detachably fitted and fixed to the pre-embedded window frame, and a transparent plate attached to the fixed window frame Is provided only on the outside (sea side or river side) of the dike wall, and a bay window-like window stand is formed on the inside (land side) of the dike wall opening. The second feature is that the transparent plate is made of acrylic resin, polycarbonate resin, or tempered glass, and a CR rubber packing is attached to the edge thereof. Further, a third feature is that a fixing bar is fixed to the edge of the pre-embedded window frame, and the fixing bar and the reinforcing bar inside the bank wall are connected. Furthermore, a fourth feature is that a curved transparent plate is attached. In addition, a fifth feature is that the see-through window is provided along the slope of the side of the bank wall. In addition, the sixth feature is that a see-through window is provided on the undercut portion where the raised bank is constructed on the existing built bank. In addition, the seventh feature is that the transparent window is rectangular or circular.

The present invention has the following advantages.
(1) It has sufficient durability against flood damage, and it is of course possible to monitor the disaster situation from the ground and roadbed surface on the land side without raising or lowering the top of the dike at the time of abnormality. Not only can you see the beautiful natural scenery of the sea and river through the perspective window, you can also ensure sufficient lighting. For this reason, even if it is a comparatively huge dike, the blockage feeling surrounded by the dike is eliminated.
(2) By attaching the transparent window to the outside of the embankment wall, that is, only to the sea side or the river side, it is possible to ensure good visibility without clouding due to moisture accumulation. Moreover, a bay window-like window stand is formed inside the bank wall opening, that is, on the land side, and the space of this window stand can be utilized. For example, a landscape from an adjacent road or house can be improved by placing a potted plant of flower buds.
(3) Since the fixed window frame is detachably incorporated in the pre-embedded window frame embedded in advance in the embankment wall, the transparent plate can be easily replaced due to breakage or aging.
(4) At the time of building the levee body wall, the formwork is assembled by welding or tightening the reinforcing bars of the pre-embedded window frame to the reinforcing bars arranged inside the levee body wall, and concrete is placed in this formwork beforehand. There is no gap between the edge of the buried window frame and the wall of the levee body. For this reason, the troublesome operation | work which fills this clearance gap with non-shrink mortar becomes unnecessary.

  Hereinafter, the see-through window structure of the embankment according to the present invention will be described based on the embodiments shown in the drawings. For convenience, the same reference numerals will be given to the same components.

  FIG. 1 shows a state in which openings 1a penetrating from both sides of a levee main body wall 1 according to the present invention, that is, from a sea side or a river side to a land side, are fitted, and a hard strength fixed window 8 is fitted. , The seaside 3 can be seen 5 through the hard strength fixed window 8 from the roadbed / basement surface 4 on the land side 2 of the levee body wall 1. It can also be used as a lighting window to the land side 2. When an abnormal force is generated from the sea side 3 due to a tsunami, storm surge 6 or the like, the wave force 7 gives an impact to the levee body wall 1 at the time of abnormality. In that case, the hard-strength fixed type window 8 receives the impact in cooperation with the levee main body wall 1 and protects a person on land, a work such as a road, or a facility such as a house from water damage.

  As shown in FIGS. 2 and 3, when the levee body wall 1 is constructed, a pre-embedded window frame fixing bar 10 mechanically joined to the pre-embedded window frame 9 by welding or the like is buried, and this pre-buried later. A hard strength fixed type transparent window 8 is fitted into the window frame 9 and fixed to the levee body wall 1. Specifically, first, a hard-strength transparent plate 13 fitted in advance to the fixed window frame 12 is fitted into the pre-embedded window frame 9, and the pre-buried window frame 9 is fastened to the levee body wall 1 with fastening bolts 15. After the fitting is completed, the backup material 21 is inserted into the gap between the pre-embedded mold 9 and the fixed window frame 12, and the caulking material 22 is filled to maintain water tightness. At that time, as will be described later, the caulking material 22a is also filled in a slight gap generated at the edge where the pre-embedded form 9 and the L-shaped steel (small) 18 are abutted. Depending on the external force acting on the transparent plate, economy, and workability of the transparent plate, an acrylic plate with good transparency, durability, and workability, or a polycarbonate plate or high-strength glass plate that is hard to break and resistant to UV rays Can be adopted and achieve the desired effect by itself without multiple layers.

  That is, the gist of the present invention is to provide an opening 1a that penetrates both side surfaces of the levee body wall 1, and a transparent material plate 13 is fitted into the opening 1a to construct a hard strength fixed see-through window 8. It is in the see-through window structure. A pre-embedded window frame 9 embedded in the levee body wall 1 in advance, a fixed window frame 12 detachably fitted and fixed to the pre-embedded window frame 9, and a transparent attached to the fixed window frame 12 By providing a transparent window 8 composed of a plate 13 only on the outside (sea side or river side) 3 of the levee body wall 1, a window-like window is provided on the inside (land side) 2 of the levee wall opening 1a. A table 23 is formed.

  Considering external force acting on the transparent plate 13, economic efficiency, and workability, made of acrylic resin plate with good transparency, durability and workability, or made of polycarbonate resin plate or high-strength glass which is hard to break and resistant to ultraviolet rays A hard and high-strength material such as a plate is preferably used. The pre-embedded window frame 9 and the fixed window frame 12 of the hard-strength fixed see-through window 8 are preferably made of a stainless steel material having a high antirust function. Moreover, it is preferable that the fixed reinforcement 10 of the pre-embedded window frame 9 is also rust-proofed.

  FIG. 4 is an enlarged view of a main part showing a state in which the fixed window frame 12 is fitted into the pre-embedded mold frame 9 according to the present invention and fastened with the fastening bolts 15 and then the backup material 21 is inserted and the caulking material 22 is filled. FIG. An anchor bolt 11 for fastening the fixed window frame 12 is mechanically joined to the rear surface of the pre-embedded mold 9. The fixed window frame 12 has a structure in which a CR rubber buffer packing 14 is attached to both sides and fixed to the four sides of the hard strength transparent plate 13 so as to be integrated with the hard strength transparent plate 13.

  The fixed window frame 12 is configured by connecting an L-shaped steel (large) 16, a deformed T-shaped steel 17, and an L-shaped steel (small) 18. The L-shaped steel (large) 16 and the deformed T-shaped steel 17 are connected by fastening bolts 19. Further, a grub screw 20 is attached to the deformed T-shaped steel 17, and an L-shaped steel (small) 18 is mechanically joined to the tip thereof. Then, by tightening the captive screw 20, the CR rubber buffer packing 14 affixed to the four sides of the front and back surfaces of the hard-strength transparent plate 13 is crimped. Later, the back-up material 21 and the caulking material 22 are filled in the gap between the pre-embedded window frame 9 and the fixed window frame 12, and the slight gap generated at the edge where the pre-embedded form frame 9 and the L-shaped steel (small) 18 are abutted is formed. In addition, the caulking material 22a is filled to ensure watertightness, and the mounting bolt 15 for fixing the window frame 12 is covered and protected. This also prevents mischief.

  Further, in the present invention, when the levee main body wall 1 is constructed, the formwork is assembled by welding or tightening the fixing bars 10 of the pre-embedded window frame 9 to the reinforcing bars arranged inside the levee main body wall 1, and the concrete is attached to the formwork. The gap between the edge of the pre-embedded window frame 9 and the levee body wall 1 is prevented from being generated. In the construction of a conventional general dike wall, there is a gap on the outside of the formwork. First, an opening having a size larger than the outer size of the window frame is provided on the wall surface, and a window frame having an outer size smaller than this opening size is fitted and opened. After the window frame is welded and fixed to the anchor bolt or the like inserted in the field, an operation of filling the gap with non-shrink mortar is required. However, according to the present invention, such a troublesome operation is unnecessary.

  In addition, when replacing the hard strength fixed type see-through window 8, the caulking material 22 is removed, the back-up material 21 is removed, the mounting bolt 15 is removed, the new see-through window 8 is fitted, and the backup member 21 is then re-inserted. The structure can be easily replaced by inserting and refilling the caulking material 22.

  As shown in FIG. 5, the design is appropriately performed according to the construction conditions of the levee main body wall 1, and various shapes of the hard-strength fixed-type see-through window 8 can be considered without departing from the gist of the present invention. For example, FIG. 5A shows a case where a hard-strength fixed type see-through window 8 is fitted in a curved concave shape on a wave return wall such as a coastal dike, and FIG. Fig. 5 (c) shows a case where the wall is fitted to a levee wall constructed of a secondary concrete product on a coastal dike or a river dike. FIG. 5 (d) is a view in which a hard strength fixed type see-through window 8 is fitted to a cut-down portion where a raised embankment is constructed on an existing built embankment.

  Alternatively, the entire hard strength fixed type see-through window 8 may be deformed. For example, as shown in FIGS. 6E and 6F, the hard strength transparent plate 13 is formed in a semi-cylindrical shape, and the levee body wall is formed. You may make it protrude in the sea side 3 of 1 and attach it vertically or horizontally. FIG. 6 (g) shows an example in which a ship's window is imitated into a circular shape and attached.
