【考案の詳細な説明】
この考案は、Ｕ字溝の左右側壁上部の突設部に
縦割切欠部を設けたＵ字溝に関するものである。[Detailed Description of the Invention] This invention relates to a U-shaped groove in which vertically divided notches are provided in the protruding portions of the upper left and right side walls of the U-shaped groove.
従来、Ｕ字溝を地中に埋設する場合、該Ｕ字溝
の巾より広い溝を掘削し、溝の底部に砕石及びコ
ンクリート基盤等を敷設し、その上面にＵ字溝を
載置して、相互に連結して一連の下水溝を形成し
ていた。 Conventionally, when burying a U-shaped trench underground, a trench wider than the width of the U-shaped trench is excavated, crushed stone and a concrete base, etc. are laid at the bottom of the trench, and the U-shaped trench is placed on top of it. , which were interconnected to form a series of sewer ditches.
しかし、Ｕ字溝の形状は本体上部に蓋載置部を
設けるために左右側壁の上部が突設しており外周
壁に凹凸を有し、地中で隙間なく一体に固定させ
ることは困難であり、上部外壁部と地表との接続
部より侵入した雨水や排水等がＵ字溝の側壁を伝
わり側壁下部の空洞部に流れ込む恐れがあつた。 However, the shape of the U-shaped groove is such that the upper parts of the left and right side walls protrude in order to provide a lid placement part on the upper part of the main body, and the outer peripheral wall has unevenness, making it difficult to fix it in one piece underground without any gaps. There was a risk that rainwater, drainage water, etc. that entered through the connection between the upper outer wall and the ground surface would travel along the side walls of the U-shaped ditch and flow into the cavity at the bottom of the side walls.
特に民家と道路の間にＵ字溝を隣接して設けた
場合、自動車等の通過振動により、Ｕ字溝と民有
地との接続部との剥離から上記雨水、排水等が流
れ込むことによりＵ字溝付近の地盤を洗い流して
下部空洞部に落下し、隣接する建造物の基礎が陥
没、あるいは傾斜してしまう危険性が生じる。 In particular, when a U-shaped groove is installed adjacently between a private house and a road, the vibrations of passing cars, etc. can cause rainwater, drainage water, etc. to flow into the U-shaped groove from the separation between the U-shaped groove and the private land. There is a risk that the ground near the ditch will be washed away and fall into the cavity below, causing the foundations of adjacent buildings to cave in or tilt.
本考案は上述の事情に鑑み考案されたものであ
り、Ｕ字溝の下部側壁に、正ずる空洞部を発生し
ないようにし、建造物に隣接しても側壁部の土壌
が流れ込むことを防ぐ目的としたものである。 This invention was devised in view of the above-mentioned circumstances, and its purpose is to prevent the formation of a vertical cavity in the lower side wall of a U-shaped ditch, and to prevent the soil from flowing into the side wall even if it is adjacent to a structure. That is.
その構成の実施例を図面に基づき説明するに、
略Ｕ字状の横断面を有するＵ字溝本体１′の一方

縦割切欠部４を設けてなるものである。 An example of the configuration will be explained based on the drawings.
Vertical notches 4 are provided at appropriate locations on a protrusion 3' at the upper part of one side wall 2' of a U-shaped groove main body 1' having a substantially U-shaped cross section.
尚、切欠部４は図２に示すように側壁の端部に
設けることも可能であり、図面のように一方の側
壁部だけではなく、両方の側壁部にも切欠部を設
けることも可能である。 Note that the notch 4 can be provided at the end of the side wall as shown in FIG. 2, and it is also possible to provide the notch not only in one side wall as shown in the drawing but also in both side walls. be.

とができ、埋設後においても土圧等の外部圧に十
分耐え、側壁の土壌も崩れ落ることはない。 The U-shaped groove according to this invention is constructed as described above, and to explain the actual construction, a groove approximately the same width as the U-shaped groove is excavated, crushed stones 7, etc. are laid at the bottom of the groove, and the upper part is A base concrete 8 is filled, reinforcing bars 9 are placed on the base concrete in advance along the notch, and reinforcing bars 11 are stretched parallel to the longitudinal direction of the U-shaped groove in the lower side wall cavity 10 of the U-shaped groove. By connecting the planted reinforcing bars 9 and filling the notch 4 with concrete using the injection port, the cavity 10 at the bottom of the U-shaped groove can be reliably backfilled, and the earth pressure can be maintained even after burial. It can withstand such external pressures, and the soil on the side walls will not collapse.

全に埋るので外観も良好となる極めて実用的な考
案である。 As mentioned above, when conventionally burying a U-shaped trench underground, there is a disadvantage that the cavity cannot be filled in advance unless the trench is excavated wider than the width of the U-shaped trench, especially when it is adjacent to a building. However, with this invention, even if the U-shaped trench is buried closely, it is impossible to excavate at all, leaving a hollow space between the U-shaped trench and the ground. Since it can be filled, it does not create a cavity, and since the notch groove is completely filled, it has a good appearance, making it an extremely practical idea.
