土留装置の改良に関するものである。[Detailed explanation of the invention] (Field of industrial application) This invention relates to earth retaining equipment, which is used when burying various types of pipes such as water and sewage pipes, gas pipes, oil pipes, and cable storage pipes in the ground. This invention relates to improvements to earth retaining devices that prevent the collapse of ditches.

させるものがある。(Prior Art) Conventionally, various types of pipes are buried underground using various means to prevent the excavated trenches from collapsing. In particular, various large-scale earth retaining devices have been proposed for use in main pipe construction or soft ground, but on the other hand, they cannot be used in narrow spaces, narrow side streets, or within structures such as station premises, where it is difficult to bring in large machines such as cranes. The reality is that earth retaining devices that can be assembled manually, such as those used, are not necessarily satisfactory in terms of assembly work, strength, and other aspects. For example, an earth retaining means that supports a sheet pile such as a steel plate that is supported in contact with both side walls of an excavation trench with jacks through supporting materials called horizontally arranged Since there is a risk of displacement in the vertical direction, the supported sheet piles may become inverted. In addition, the jack proposed in Japanese Utility Model Publication No. 58-45319 as one of the ground pressure bearing jacks for this purpose is structurally complex and cumbersome to operate, so it is usually not used in places with a lot of earth and sand. Considering this, it had to be handled with care. On the other hand, by arranging frames front to back, left, right, top and bottom and combining them, a steel support in the shape of a rectangular parallelepiped is formed, which is suspended in an excavation trench, and the left and right frames abut and support the sheet piles. There is.

時での拡幅調整は困難であつた。(Problem that the invention aims to solve) However, in this case, the frame itself is bulky and inconvenient to handle, and the spacing adjustment corresponding to the width of the excavation groove is difficult to do between the frames that are fitted twice. Because of the locking pin that penetrates the ground, it was difficult to adjust the width when supporting earth pressure.

It is an object of the present invention to provide an earth retaining device which is robust enough to withstand earth pressure, is lightweight and easy to handle, and has excellent workability.

0 supports a sheet pile W made of wood or steel that is arranged in a standing leg shape on the outside of the upright 30 in order to support the earth pressure received from both side walls in the trench D, and the upright 30 is directly connected to the upright 30. Support this by combining. As shown in FIG. 3, the jack support 40 has a feed screw rod 43 inserted and fixed into an outer cylinder 41 whose one end is closed by a closure piece 42, and one end of the feed screw rod 43 protruding from the closure piece 42. In addition, a feed nut 52 connects a gripping arm 47 having a U-shaped cross section and fits externally to the riser 30, and is screwed to the feed threaded rod 43.
An inner cylinder 51 with a
At the other end of the inner cylinder 51 that goes out from the outer cylinder 41, there is a bulge 3.
It is composed of a gripping arm 54 having a U-shaped cross section that is fitted onto the outside of the nut, and when either the outer cylinder 41 or the inner cylinder 51 is rotated, the screw feeding action of the feed screw rod 43 and the feed nut 52 is activated. Therefore, the inner cylinder 51 protrudes and retracts from the outer cylinder 41, so that the overall length can be freely adjusted. In addition, 44 is the feed screw rod 43
This is a detachment prevention portion formed at the end, and prevents the inner tube 51 from detaching when it comes out from the outer tube 41 due to the screw feeding action.

にしてある。 In the illustration, one of the gripping arms, for example, the outer cylinder 4, is used to enable expansion and contraction adjustment of the overall length even when the left and right belly risers 30 are horizontally fixed between each other.
The gripping arm 47 connected to 1 is rotatable,
Specifically, a connecting ring 45 is attached to the feed screw rod 43 by a plate 46 fixed to the rear surface of the deep bottom of the gripping arm 47, which fits onto one end of the feed screw rod 43, and abuts against the surface of the plate 46 to prevent it from coming off. By fixing it to one end, the gripping arm 47 can freely rotate.

For example, as shown in the figure, the inner cylinder 51, the connecting cylinder 5
3. They are connected by pin means 1 and 2 that penetrate through both. Then, as shown in FIG. 8, a long cylindrical manhole support 56 is attached to the manhole support 5.
6 is connected to the inner cylinder 51 via pin means 1 and 2 by a stepped portion 57 formed on itself, and further connected to the connecting cylinder 53.
By combining the two, it is possible to widen the distance between the uprights 30 in the left and right direction, which has the advantage of being able to be used, for example, to support earth pressure at a large-diameter manhole construction site.

By slidingly inserting the inner cylinder 51 into the inner peripheral edge of the cap 49, it is possible to prevent dirt and other objects from entering the outer cylinder 41. The screw feeding action should be smooth in order to prevent dirt from adhering to the screw. Then, by rotating the cap 49 and furthermore the outer cylinder 41 using the jack handle 60 which has an operation pin 61 that engages with an operation hole 50 formed in the cap 49, the outer cylinder 41 and the inner cylinder 51 are connected to each other. This allows for relative movement of the parts, making the expansion and contraction work easier.
