Trench

Abstract

The invention discloses a trench which is formed by sequentially connecting a plurality of trench bodies. The trench body is formed by stainless steel plates through die pressing, the cross section perpendicular to the axial direction of the trench body is U-shaped, the axial end of the trench body is radially and outwards expanded to form an outward expanded portion, the other end is a smooth end, the inner size of the outward expanded portion is not smaller than the outer size of the smooth end, the outward expanded portion of the trench body is in sleeved connection with the smooth end adjacent to the trench body, a sealing part for preventing water leakage of junctures is arranged between the outward expanded portion and the smooth end, riveting holes corresponding in a one-to-one mode are respectively formed in the outward expanded portion and the smooth end, and the adjacent trench bodies are mutually and fixedly connected through rivets in the riveting holes. The butt joint of the adjacent trench bodies is field riveting, the butt-jointjunctures are sealed are by utilizing sealing parts, the technical effect of fireless butt joint is achieved, the riveting speed is higher than welding speed, and welding deformation and other adverse factors do not exist. Therefore, the construction cost can be remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of sewage, and in particular relates to a trench. Background technique [0002] As an underground drainage and sewage facility, floor trenches are widely used in large shopping malls, bathrooms, squares, parks and other places. , the ground trench is a continuous groove with a certain length. Traditional ground trenches include brick trenches, cement trenches, and iron sheet trenches. The construction period of brick trenches and cement trenches is relatively long. The progress is slow and the construction site is relatively complicated. When the iron sheet trenches are laid on site, the progress is fast. However, the iron sheet trenches are formed by welding the first parts of the groove bodies and are laid in deep trenches under the ground. Therefore, the site needs Open flames are used, welding is inconvenient, the construction process is complicated, the welding effect varies from person to person, and ...
