Claims (7)
1. » A trench shoring frame which is adapted to move along the trench when located therein* comprising a pair of side wall structures for engaging toe side walls of a ground ■ trench* said side vail structures being supported in spaced apart relationship so as to be capable of supporting the trench vails* said shoring frame having movably connected thereto a caisson or vertical plate means novable relative to the side wall structures and into and out of the ground below the loner extremities of the side wall structures by one or more fuid pressure operated jacks connected directly to said vertical plate means or caisson.
2. * A trench shoring frame as claimed in Claim 1* wherein said vertical plate means is constituted by a plurality of vertical plates which are disposed substantially parallel to and spaced from said side wall structures*
3. $· A trench shoring frame as claimed in Claim 2, wherein said vertical plate means includes at least one vertical plate located transversely to said vertical plates which are parallel to the side wall structure*
4. « A trench shoring frame as claimed in Claim or Claim 9 wherein said vertical plates are secured individually to the pistons of luid pressure-operated jacks so as to be movable with said pistons upon actuation of said jacks*'
5. * A trench shoring frame as claimed in Claim 4* wherein said jacks are carried by structure of the shoring frame*
6. * A trench ehoring frame as claimed in Claim 1, wherein said caisson is constituted by a three-saded '.wedge-shaped member having a pair of epaced-apart side walls and a front wall* said side walls being ^ivotally secured to structure of the trench shoring frame. 7. A trench shoring frame as claimed in Claim 6, wherein the forward end of said wedge-shaped member is secured to the pistons of two fluid pressure-operated jacks mounted on structure of the shoring frame so as to be movable with said pistons on actuation of said jacks*. 3. A trench shoring frame as claimed in Claim 6 or
7. Claim 7, wherein the upper surface of said wedge-shaped member is adapted to be substantially horizontal when said wedge-shaped member is fully inserted into the ground. 9. A trench shoring frame as claimed in any of the preceding Claims, including a rigid thrust plate structure which is connected to the side wall structures by a plurality of double-acting fluid pressure-operated jacks, whereby upon actuation of the jacks the thrust plate structure and side wall structures may move relative to each other to cause advancement of the shoring frame in the direction of the trench. 10. A trench shoring frame as claimed in any of the preceding Claims, wherein the leading ends of the side wall structures are formed as cutting edges. 11. A trench shoring frame substantially as herein described with reference to and as illustrated in Figure 1 or Figure 2 of the accompanying drawings.
