Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a pricking device which is laterally mounted on the surface of a soil retaining plate.

[Conventional technology]

Generally, when earth-cutting the root-cutting, as shown in FIG. 4, the earth-holding plate 12 such as a sheet pile is driven into the side of the root-cutting to prevent the earth and sand around the root-cutting from collapsing. Board
12 attaches the tube 1 for abdomen to the side of this to prevent it from bending.

Conventionally, the abdomen waving tube 1 is made of this single substance, and is used as an earth retaining plate.
Each of them is attached to the surface of 12 with a burrs 13 while overlapping the end portions 1a with each other.

[Problems to be solved by the device]

However, in the construction in which the belly-raising pipes 1 are attached one by one with the beam 13, the ends of the belly-raising pipe 1 at least in the longitudinal direction, which are to be overlapped, are not detached. Since it is necessary to press the position near the portion 1a with the cut-outs 13, at least two cut-outs 13 must be used for each abdomen rising tube 1.

Therefore, the number of the cut-outs 13 required for the belly-raising construction using a large number of belly-raising tubes 1 is very large,
It was a cause of a decrease in soil retaining work efficiency. Further, if the cutouts 13 are often used, the cutouts 13 become an obstacle to the work at the bottom of the root cutting, for example, when deepening the root cutting or burying a communication cable. In particular, as shown in Fig. 4, when earth-cutting a root excavation excavated in a curved shape, the ends 1a and 1a of the abdominal waving pipe 1 attached along the inner circumference of the earth-cutting should intersect each other. However, in this case, the end portion 1a projects out, and it is difficult to work at the root cutting bottom in this respect as well.

In addition, the length of one of the tube 1 for abdominal recoil is large (usually 3
m), and because the number of cutting beams 13 used is large, it was also inconvenient for transporting them.

The present invention has been made to solve these problems, and by giving one belly rising device a function capable of bending more than two folds or three folds and a function capable of changing the length thereof, The purpose is to reduce the number of cuttings used and to ensure work safety and efficiency.

[Means for Solving the Problems]

As shown in the illustrated example, at least two or more abdominal waving pipes 1 according to the present invention have end portions 1a, 1a of the abdominal waving pipes 1, 1 joined by a joint 2 so that they can be bent and expanded. And The joint 2 includes two joint pipes 3 and 3 and a pair of joint links 4 both ends of which are flexibly pivotally connected to one end 3a of the joint pipe 3 3 by a joint pin 5 respectively. 4 and the other end 3b of the joint pipe 3 is inserted into the end 1a of the belly-raising pipe 1 so as to be freely inserted and removed. The end 3b of the joint pipe 3 and the end 1a of the abdominal rising pipe 1
Locking means 6 is provided for locking and retracting. The locking means 6 includes a pin hole 7 provided at the end 3b of the joint pipe 3 at a predetermined pitch in the longitudinal direction thereof, and a pin hole 8 provided at the end 1a of the belly-raising pipe 1 with respect to each other. The lock pin 9 is configured to be inserted into and removed from the matching pin hole 8 and the pin hole 7, and the lock pin 9 is attached to the joint 2 with the connecting member 10.

[Action]

At that time, since the abdominal rising tubes 1 and 1 can be bent at an arbitrary angle with the joint 2 as a node, a shape along the curve can be applied to the earth retaining plate 12 that is excavated in a curved shape. It can be installed easily.

In addition, the length of the belly-up device along the circumference is longer than the length of the belly-up device along the inner circumference of the curve,
At this time, expansion and contraction can be adjusted according to the difference in length.

When the cut-off beam 13 is laid horizontally between the inner peripheral side bellows raising tube 1 and the outer circumferential side bellows raising tube 1 opposite thereto, the adjacent belly raising tubes 1 are arranged next to each other. Since the end portions 1a and 1a of 1 are connected to each other by the joint 2, it is sufficient for the cutout 13 to hold one central portion in the longitudinal direction against one bellows raising tube 1.

When the joint 2 is straightened to straighten the belly-raising pipes 1 and 1, it can be applied to earth retaining of excavated roots.

〔Example〕

An embodiment of the earth retaining clenching implement according to the present invention will be described with reference to FIGS.

In FIG. 3, this abdominal riser comprises at least two abdominal rise tubes 1 and end portions 1a of the abdomen rise tubes 1.1.
1a Combined with the joint 2 that connects them. The belly-raising tube 1 is made of, for example, a rectangular steel tube having a length of 1 m. The joint 2 has two joint pipes 3 and 3 made of a rectangular steel pipe or the like having an inner diameter smaller than the inner diameter of the end 1a of the abdomen rising pipe 1, and the one ends 3a and 3a of the joint pipes 4 and the joint pin 5 are connected to each other.・ It is flexibly pivotally connected at 5. The pair of joint links 4 and 4 have both ends thereof respectively overlapped with the one ends 3a and 3a of the joint pipe bodies 3 and 3 and are pivotally connected by a joint pin 5 so as to be bendable.
In this joint 2, the end portion 3b of the joint pipe body 3 is reentrantly inserted into the end portion 1a of the pipe body 1 and the end portion 1a is
On the other hand, it is provided with a locking means 6 that locks in a telescopic manner. As the locking means 6, a pin hole 7 is provided at the end 3b of the joint pipe body 3.
Are provided at a constant pitch in the longitudinal direction thereof, while one pin hole 8 is provided at the end 1a of the tube 1 for abdomen uplifting, and the lock pin 9 which can be freely inserted into and removed from the pin hole 8 is provided in any one of the pin holes 7. By inserting it in, the ends 1a and 3b are restricted from expanding and contracting. The lock pin 9 is attached to the joint link 4 with a connecting member 10 such as a chain so that the lock pin 9 is not lost.

A cutout beam receiver 14 is superposed and fixed to the central portion in the longitudinal direction of the upper surface of each of the bellows raising tubes 1, and a fastening bolt 15 is screwed into the cutoff beam receiver 14. On the other hand, as shown in FIG. 1 and FIG.

The abdomen erector thus constructed is used in the following manner. As shown in Fig. 1, root cutting that excavates the ground in a curved shape
Earth retaining plates 12 such as steel sheet piles are intermeshed around the inner circumference and the outer circumference of 11 so as to be closely attached and driven. The abdomen erection tool is attached by shavings 13 laying sideways with respect to the respective surfaces of the earth retaining plate 12 on the inner and outer sides thereof, at this time,
Since the belly-raising device can rotate the belly-raising tubes 1 and 1 with the joint 2 to bend the belly-raising tube 1 at an arbitrary angle, the belly-raising tube can be applied so as to properly follow the arched surface of the earth retaining plate 12. .

In addition, the cut-off beam 13 is horizontally laid between the inner circumference abdominal rising tube 1 and the outer peripheral abdominal rising tube 1, but in this case, the belly rising tube 1 is formed. .1 end 1a
-Since 1a is connected by a joint 2 and cannot be disengaged, it suffices to pass one tube between the inner and outer bellows raising tubes 1 and 1 only in the central portion in the longitudinal direction.

At this time, as shown in FIG. 1, both ends of the cut-off 13 are butted at right angles to the central portion in the longitudinal direction of the bellows raising tubular body 1 on the inner peripheral side and the outer peripheral side, and the ends of the cut-off 13 are attached. The plate 13a is placed on the cut-out bridge 14 and tightened with the tightening bolts 15. To this end, by making the length of the abdominal riser on the outer circumference side longer than the length of the abdomen riser on the inner circumference side, the abdomen riser tube 1 of the inner circumference side abdominal riser and the bellows rising pipe on the inner circumference side are opposed to this. It is necessary to align the both ends 1a and 1a with the abdominal riser tube 1 of the abdominal riser on the outer peripheral side, but at this time, the lock pin 9 is pulled out and the end 1a of the abdomen riser tube 1 is pulled out.
The length can be easily adjusted by adjusting the insertion depth of the joint 2 relative to each other.

It can be applied to a root excavated earth retaining plate that has been excavated straight by straightening the joint 2 of the abdominal rising tube 1, 1 of the abdominal rising device.

[Effect of device]

According to the earth retaining bellows raising device of the present invention, since the ends 1a of the plurality of belly raising tubes 1 are connected to each other by the joint 2, the bellows raising tube is attached to the surface of the earth retaining plate 12. End of body 1
With 1a, there is no need to press the cuts 13 further, and the number of cuts 13 used can be reduced accordingly. As the number of cut-offs 13 decreases, the abdominal work can be performed efficiently, and the work at the root cutting can be performed safely.

In addition, since the belly-raising pipes 1 and 1 are connected to each other via the joint 2 so as to be bendable and expandable, not only straight root cutting but also curved root cutting soil. The retaining plate 12 can also be properly attached along the curve so as to ensure the safety work without protruding the end portion 1a of the tube body 1 for raising the abdomen, and moreover, the inner periphery and the outer periphery of the curve can be attached. It is convenient to handle because it is possible to use the same structure by adjusting the length without having to use different pouchers.

Further, the length of one tube 1 for abdominal rising can be set shorter than that of the conventional one, and the joint 2 has the joint tube 3/3.
While being inserted into the tube 1 for upsetting, or withdrawn, the joint tubes 3 and 3 are refracted via the pair of joint links 4 and joint pins 5 to be compact so as to overlap each other in parallel. Since they can be folded, they are also advantageous in transporting them all at once. Further, the lock means 6 for locking the joint tube 3 and the bellows raising tube 1 has pin holes 7 provided at the end portion 3b of the joint tube 3 at a predetermined pitch in the longitudinal direction, and the bellows raising tube 1 of the bellows raising tube 1. Since one pin hole 8 provided in the end portion 1a is made to match each other and the lock pin 9 can be inserted / removed into / from this, the joint pipe body 3 and the abdominal rising pipe body 1 can be manually operated without using any tools. The workability is excellent because the and can be easily adjusted for expansion and contraction. In addition, the lock pin 9 attached to the joint 2 with the connecting member 10 is not lost, which also contributes to improvement in workability.
