Abstract
The utility model relates to a glass fiber reinforced plastic and sand included pipe jacking comprising a pipe shaft provided with a sand inclusion layer and a pipe head taking the resin as the base and the glass fiber as a reinforced layer and using for connecting with other pipe jacking. The external diameter of the pipe head is smaller than that of the pipe shaft. One or a plurality of grooves used for covering of a rubber sealing ring is arranged on the external surface of the pipe head; the sand inclusion layer is arranged inside the pipe head, of which the thickness is smaller than that of the sand inclusion layer of the pipe shaft. The thickness of the sand inclusion layer of the pipe head increases progressively in the direction from the pipe head to the pipe shaft; the sand inclusion layer and the sand inclusion layer of the pipe head can be arranged in integral or according to the pipe head section or the pipe shaft section respectively. The distance between the external surface of the sand inclusion layer and the sand inclusion layer of the pipe head is larger than the depth of the groove. Because of the rational design of the sand inclusion layer of the pipe head, the utility model not only guarantees the bearing ability of the jacking force, but also reduces the cost of the glass fiber reinforced plastic & sand included pipe jacking maximally.
