Abstract

PURPOSE:To prevent damage of a flexible cut-off member during and after driving, by a method wherein a pair of laminar parts are intercoupled by means of the flexible cut-off member to form the joint of a steel sheet pile, and a protecting plate part, covering the flexible cut-off member, is provided in series connection to the one side of the laminar part. CONSTITUTION:Fastening parts 2b and 2b' are attached to a pair of laminar parts 2 and 2' having joint parts 2a and 2b for connection of adjoining steel sheet piles with each other. A flexible cut-off member 1 made of rubber is extended between the fastening parts 2b and 2b' and are secured by means of bolt nuts 3 and 4 to form a joint A for the steel sheet pile. Further, thin sheets 5b and 5b' are welded to base parts 5a and 5a' of the one planar part 2 to form protecting plate parts 5 and 5'. This, since the thin sheets 5b and 5b' are not secured to the other planar part 2' prevents disturbance of deformation yielding as the joint, and enables the flexible cut-off member 1 from being damaged.

1 bank, 1 bank, revetment, earth retaining, 7 walls! 7-ei 1 is widely used for all types of 9-degree construction work such as embankments. Conventional steel sheet piles slide at mutual joints and undergo shearing displacement when ground displacement due to soil MK or loosening of the ground due to rainwater occurs.
In order to prevent compression deformation and deformation due to the horizontal connection, the engagement and disengagement of the steel sheet piles (j is the function of the '1l11i sheet pile by causing destruction and deformation of the steel sheet piles, or - It caused damage to structures dependent on the sheet piles.

Therefore, the present applicant previously proposed, with Special Application No. 168333 of 1939, a flexible stop made of rubber, synthetic resin, etc., between the plate-like parts that form the joints with the adjacent steel sheet piles. I proposed a fitting that spanned the water component. Since this joint is installed at the water stop section &7j;Ill of the control sheet pile, it is likely that the steel sheet pile will often retreat due to displacement of the steel sheet pile due to ground movement, etc. Therefore, steel sheet piles do not break or fall down due to ground movement, etc., and steel sheet piles can sufficiently develop their functions and improve their durability. It can be improved.

However, since the steel sheet pile joint proposed above uses a water stopper made of rubber or synthetic wood,
When pouring this joint, there is a problem in construction that it is easy to cause hot water to come out such as cracks in the water stop member due to t = J, and -rl
When constructing a tomb, there is a risk that the flexible water-stopping member may be easily damaged due to contact with sharp rocks, etc. of the temple due to ground movement. In order to do so, it is essential to first solve these interpolations.

Purpose of the invention The invention was made with the aim of solving the above-mentioned various quantities of concrete and pouring screw for the joints of steel sheet piles using iJ Butsu water-stopping members. Although it is a joint that uses the T'J'A water stop part, there is a 'T'H' when installing the joint and at the pouring ridge! The purpose is to provide a sheet pile joint +J6 and its painting method that eliminates the possibility of water supply components being discovered.

DESCRIPTION OF THE INVENTION In order to achieve the above-mentioned object, the inventive joint of steel sheet piles is provided such that both 41111K are adjacent to each other. Rubber/synthetic +?

If it is sufficient to protect only 〇〇1 for the purpose of preventing the use of 6J water-stopping member l due to contact with The protector on the other side can be pulled out.

In this embodiment, the plate-like parts 2 and 2', which are formed by halving a U-shaped steel sheet pile, have two cylindrical parts 1c and lc.
It is connected by J flexible water stop part Iol. - On the 10,000 side of the 10,000 plate part 2, a protection plate part 5 consisting of a base 5a and a thin plate part 5b is connected, and the other plate part 2' is provided with an auxiliary protection plate part 5.
Section 6 is provided in series. On the other side of the plate part 2.2' is a protective plate part consisting of an outer 1111 presser member 14 consisting of an L-shaped plate knife and a corresponding inner 411+1 presser part @'15 in the shape of a round bar. A retaining member 14 is provided. Outside 1i1
11 The holding member 14 has a web portion 14a (1) Water stop member fixing portions 2b, 2'b whose ends are plate-shaped portions 2, 2'.
The flange portions 14b are connected to the outside 11111 of the joint, and the flange portions 14b are 0J (5Vc) connected to the water stop member 1 and the flat material at the same center.

A protective plate I6 made of a U-shaped steel material or the like is mounted between the beams between the outer valve portion M14 of the thus formed plate-like member (fil+) and the inner holding member 15. The protective plate 16 is prevented from moving outward (0 by the unpressing member 14) in the vertical direction outward 114+1 with respect to the surface of the water-reflective water stop member 1, but sliding in the direction of the line 1 of the joint is on the river surface. .

S, inner 111+1 presser member 15 is a steel sheet pile that is momentarily contacted when the flexible water stop member l expands to receive the force that opens the plate parts 2.2' in the direction of separating from each other when pouring the joint. The gap between 1'J'8 of the joint is provided with a groove that prevents the buried position from becoming inaccurate as a result of displacement of the entire joint 114+1 opposite to the side engaged with the joining joint. In order to prevent the protective device 16 from slipping up, it is common to temporarily fix the appropriate openings of the protective device 16 to the plate-like portions 2 and 2' by tightening bolts. Remove the temporary fixing of the protection plate 1 (i) and pull out the plate 16. Since it is restrained by the a-plate 16, it is not necessarily necessary to temporarily fix the protection plate part 5.

It is possible to insert the step into the middle – and also to install the fittings &
We have shown an example where the upper end of joint A is cut into 1, but this
The upper end is opened, and the lid material 13 is attached by a method that allows easy removal, such as bolting, without using the stopper member 12. If it is fixed to the upper end of +A, there is no need to worry about cutting the upper end of the person connecting the pouring steps.

1. A pair of J-shaped braces/4- are fixedly fixed to the stopper member fixing parts 11 and 11, and the foot parts 13a and 13a of the lid member 13 are fixed.
The lid material 13 is stopped on the outside of these stoppers.
If you place the IE part 12, you can stop it without using the IE member 12, and without having to bolt the lid attached to the f15 hitting direction fixing part 11 and 11, without using bolts. This is done by fixing the member fixing parts 11 and II to each other.

The above example of Tanioma and the east side of f are examples of using the inventive joint as a joint for U-shaped steel sheet piles, but the inventiveness is not limited to the large number of U-shaped steel sheet piles. Direct #Jl
It can also be used as a joint for steel sheet piles of shape, Z shape, steel pipe Daikariji, and other types of steel sheet piles.

Therefore, when applying the invention to the joining of inclined steel sheet piles other than U-shaped, the shape of the plate portion 2 is not limited to the U-shaped steel sheet pile cut in half as in each of the above embodiments, Various modifications are possible depending on the type of steel sheet pile.

Since the protective plate part is provided in series to cover the effect of the invention, the protective plate part protects the flexible water-stopping member during and after the joint is cast, and effectively prevents damage such as cracks to the flexible water-stopping member. On the other hand, after the joint is cast, the flexible water stop section 4A, regardless of the presence of the protection plate section, expands and contracts following the displacement of the steel sheet pile due to ground movement, etc.
It is possible to freely bend and shear deformation, thereby significantly improving the durability of the steel sheet pile without causing damage to the steel sheet pile.

1) The construction method of the present invention is to join the bottom of the leading rigid flexible water-stopping member to the lower end of the steel sheet pile joint with the above structure, and to apply a load to the upper end of the joint to sink it into the soil. Because it is installed by pouring and burying, it is possible to protect not only the sides but also the bottom of the flexible water-stopping member during pouring, and there is no damage to the flexible water-stopping member. Push-in embedding is easy because it leads to push-in embedding.
