Abstract:
In combination:a main sewer pipe located below a surface of the ground; a lateral sewer pipe below the surface of the ground and connected in fluid communication with the main sewer pipe, the lateral sewer pipe having an interior bore, a surrounding pipe wall, and an outer peripheral surface to the surrounding pipe wall; an access hole in the surrounding pipe wall of the lateral sewer pipe providing communication from outside the lateral sewer pipe into the interior bore of the lateral sewer pipe; an excavated hole in the ground providing communication from the access hole in the lateral sewer pipe to the surface of the ground; an access assembly within the excavated hole and having a saddle surrounding a portion of the outer peripheral surface of the lateral pipe and an access pipe extending upwardly therefrom, the access pipe having a lower end extending through the saddle and having an upper end adjacent the surface of the ground; the access pipe also having an internal bore providing communication from the upper end thereof to the lower end thereof to the access hole in the lateral sewer pipe, whereby the internal bore of the access pipe provides access from the upper end thereof to the interior bore of the lateral sewer pipe; the saddle of the access assembly comprising a curved plate conforming to the outer peripheral surface of the lateral sewer pipe, the outer peripheral surface of the lateral sewer pipe extending in a circle 360 degrees, the curved plate surrounding more than 180 degrees of the outer peripheral surface of the lateral sewer pipe; the curved plate comprising a flexible material that permits the curved plate to flex in an outward radial direction and then snap back to its original curved configuration in response to downward pressure applied to the access pipe from above the surface of the ground during the connection of the curved plate to the outer peripheral surface of the lateral sewer pipe.
