Title: Foamed resin member installed along member pressured by earth pressure
Inventor: MURASE HIROYUKI
IPC: E02B13/00
Filed: 1989-08-07
Abstract: PURPOSE:To relieve earth pressure in the case where frost heave occurs to the ground by providing foamed resin members to the sides whereto the earth pressure is applied from lateral sides of a built-up stepped ditch, U-shaped ditch or the like, and by making the upper ends covered with fire-resistive material. CONSTITUTION:A drainage ditch 1 is formed over a foundation 4. The ditch is made up of concrete blocks made from U-shaped blocks 5, and the outside of the block is covered with a foamed resin member 6 up to its upper end faces. The upper parts of the foamed resin members 6 are then covered with fire-resistive layers 10 made of a fire resistive material. Thereby earth pressure in case of frost heave can be relieved, while damage by burning in case of burning the dead grass in field can be prevented.

Abstract: PURPOSE: To improve the accuracy of the execution of works by connecting the lateral plate of a bottom plate and a vertical plate by a curved section while the underside of the bottom plate and the underside of a tooth are formed in the same surface and specifying the ratio of the length of the underside of the bottom plate to the length of the upper and lower sections of the opening section of a bucket. CONSTITUTION: Since a bucket body 10 is formed of a pair of side plates 11, a rear plate 12 and a bottom plate 13, the number of parts is reduced. B/A>=-0.55 holds in the length A of the underside 13a of the bottom plate 13 and the length B of the upper and lower sections of the opening section of a bucket 10, and the length of the bottom plate 13 is lengthened and the accuracy of finishing of linear excavation and correction operation is improved. Intrusion to an excavating surface and a correcting surface of the rear end section of a lateral plate 17 is prevented by the curved section 19 of the rear end section of the lateral plate 17, thus enhancing the accuracy of finishing.  Smooth linear excavation is enabled because the underside 13a and the undersides 20a of teeth 20 are formed in approximately the same surface while excavation resistance is reduced because the projecting sections 22 of the bottom plate 13 are projected among the adjacent teeth 20. Accordingly, the bucket can be manufactured easily, and the accuracy of finishing and working speed can be improved.
