Abstract: Disclosed is a soil blocking method using a new type of raker. According to one embodiment of the present invention, the soil blocking method using the new type of raker comprises: a first step of burying and installing a large number of H-piles and post-piles on the subject ground surface; a second step of primarily excavating the ground surface into a certain depth near the H-pile for forming a horizontal surface, and installing soil blocking members between the large number of H-piles; a third step of excavating down to the final excavation surface to be inclined from a horizontal excavation finish line; a fourth step of forming a raker support unit on the floor surface connected to a lower end of the inclined surface; and a fifth step of connecting the H-piles to the post-piles, installing a horizontal strut along with a wale parallelly to the horizontal surface of the second step, and installing a raker to connect the raker support unit and the horizontal strut around the post-piles. Accordingly, the present invention is able to, in performing a raker method, exclude an excavation height, which has been the weakest part in the conventional methods, to prevent the risk of collapse in advance, to have a structure to install a short strut horizontally on an upper end unit and connect the raker, to secure 3.0-4.0 m of width before constructing the raker, and to prevent the risk of collapse which may occur.

Abstract: The present invention relates to kitchenware. The fine vapor generated when food is placed in a container (30), and initial heat is applied can be discharged through a vapor hole (40a) provided in a lid (40). At this time, a one-side downward bar (81a) of a one-side bar (81) can be fitted into a one-side standard height vertical groove (71a) of a one-side handle (71) (to be safely fitted), and the other-side bar (82) is placed on the other-side standard height flat part (72a) at the same time so that the lid (40) can be safely set in the container (30). When heat is continuously applied to the food and the amount of the vapor increases, the one-side downward bar (81a) of the one-side bar (81) is placed on the other-side standard height flat part (72a), and the other-side bar (82) is placed on the one-side handle (71). By allowing the lid (40) to be spaced apart from the container (30) with an inclined gap (T1), it is possible to more safely eject the vapor through the inclined gap (T1).
