[Background Art] Steel sheet piles as sheet piles for quay revetment. However, this steel sheet pile is easily corroded by exposure to seawater, especially in the area between high tide and low tide called slush lean, and the area where seawater is splashed. Corrosion is likely to occur due to repeated contact and contact with oxygen in the air, and it is necessary to carry out two anti-corrosion treatments at this B13 minute. Therefore, conventionally, glass fiber reinforced cement plates (GR
C plate) is placed on the surface of the steel sheet pile, and between this GRC plate and the steel sheet pile, there is a temperature difference between the GRC plate and the steel sheet pile. By pouring it in, the steel sheet piles were prevented from being exposed to river water and were protected against corrosion. However, GRC boards have a specific gravity of 1.9 to 2, which makes them convex and heavy, making it difficult to attach GRC boards to steel sheet piles under difficult conditions such as underwater or offshore. There is a problem that it is difficult, and since it is necessary to prepare and pour mortar on site, dogs have to hunt down small pieces of equipment at the site, making the work very time-consuming. There was also the problem. In addition, GRC
It is almost impossible to perform secondary processing on the board, so the work of I, fJ clearing and drilling is done on site. However, it is difficult to carry out the collection accurately according to the situation at the site, and it is difficult to
It also had the problem of not being able to perform any rituals.

ラス繊維強化熱可塑性樹脂で形成するものである。In the present invention, the cover plate (4) is made of glass fiber reinforced thermoplastic resin. Among the glass fiber reinforced thermal OJ plastic resins, it is most preferable to use glass fiber reinforced vinyl chloride resin (FRV). F
RV has good chemical resistance and has good durability against corrosive liquids such as seawater.Moreover, it is made of paulownia material that is resistant to attack and is difficult to scrape due to the moon lath fibers being inserted vertically and horizontally. ＃There is no need to worry even if it is good. Here, the cover plate (4) can be made of glass fiber-reinforced hardening resin (FRP), but as shown in the table below, the strength of FRP is not much different from that of FRV. In addition, the specific gravity is higher and heavier than FRP (/iF RV), and the workability is poor.
It is said that secondary processing is practically impossible, cutting and drilling work cannot be done on site, and it is difficult to properly attach the protective cover according to the site conditions, and it is also impossible to carry out repairs. Due to various drawbacks, in the present invention, the cover plate +41iFRV is made of a glass fiber-reinforced thermoplastic resin as a representative example.

Next, as shown in FIG. 4(b), at the connecting portion of the adjacent steel sheet piles 11+, a fixture (3) is welded to the surface th of the front connecting piece (15). The fixture (3) is shown in Figure 6 (a) (b).

No l! ! iM'x. In this case, it is difficult to make 6 connections at the side end of the fixture +310 because there is a steel sheet pile +11 that protrudes further to the front side than the mounting bracket (6), so the resistance to the mounting bracket (3) as described above is Bomb hole tI81τ
This allows the welding work to be carried out from the front. Thereafter, a sheet-like or putty-like anti-corrosion a' +51 is pasted on the surface of the steel sheet pile il+ over the entire length. This anti-corrosion layer is preferably coated with petrolatum as its main component. Petrolatum is a type of petrolatum separated from crude oil using vacuum fish meal, and has a white or brown semi-transparent color.

When attached to a metal surface, a corrosion-resistant layer that maintains viscosity is formed semi-permanently.This corrosion-resistant layer does not suffer from cracks or holes caused by vibration or impact, or from deterioration due to sunlight or sunlight, and is suitable for steel sheet piles (4). By using this anti-corrosion layer to separate the fermentation and τ in seawater and air, the physical causes of cormorant corrosion can be completely eliminated. Rust inhibitors 1, tannin, inert silica, etc. are added to this petrolatum, and this is impregnated into non-porous fabric to form a sheet or tape, or it is solidified into a putty to form a corrosion-resistant layer (52f formation AltD Terror). The above tannin is a mixture of phenolic additives, and when it comes into contact with iron, it forms a hard, dense film called tannic ferric acid on the surface of the iron, which has the property of inhibiting the progress of rust. After pasting the anti-corrosion material (5) on the front side of the steel sheet pile fi+ as described above, cover all the cover plates (4) one by one corresponding to the six steel sheet piles il+, and cover the adjacent cover plates (
4) Flange piece t14) (overlap 141' and both flange pieces Q4) (+41 through hole [81t6) f Carry it to the bolt +21 of the cover plate (4) with a fixed window. Furthermore, similar to the flat par 07 in (3) for installation, a push-through hole L1 is formed in the vertically elongated position corresponding to the n-bolt 2).
9) Using the presser plate TSA 7 provided with this presser plate 12
3) through the push-through hole (19) and T-bolt (2), and
As shown in FIG. 3(a), screw the nut (7) onto the bolt (2) from the outside and tighten the nut (7). By tightening, the corrosion-resistant material (5) is attached to the surface of the steel sheet pile fil and the cover &
(4) Make it a dense layer on the entrance surface. The portions of the bolts (2) and nuts (7) that protrude from the cover plate (4) are sealed by applying an underwater hardening type epoxy resin tray as shown in FIG. 3(a). In addition, an earth anchor bolt (21) is attached to a part of the steel sheet pile +11, but in this part, a hole 12zt is provided in the cover & (4) to allow the head of the earth anchor bolt to escape. , Paste-like anti-corrosion material on the head of earth anchor bolt +21+ (5)
As shown in Figure 3(b), apply a plastic protector Q4Jt on the cover plate (4) outer surface at the holes and 12 parts as shown in Figure 3(b). Make sure to seal it with the moon sign (b). In this case, protector 741rFRV or hard p-vinyl chloride resin can be used as a protector.
It may also be pasted on the cover plate (4). Figure 2 (a) (bJ) at the lower end position of the cover plate (4)
As shown in K, seal with rubber tape + 25). Then, the space between the upper end of the cover plate (4) and the concrete 26 above the steel sheet pile (1) is filled with underwater curing type Ehoshiki Gokubutsuoka and sealed as shown in Fig. 4 (C1). In the above example, the anti-corrosion material (5) was pasted on the surface of the steel sheet pile il+ and then the cover plate (4) was covered.

There is no need to bring large swords and sandal equipment to the site.

、構造上簡単なものにすることができるものである。In addition, the cover plate made of glass fiber-reinforced thermoplastic resin has flexibility and can be easily mated with anti-corrosion materials. Or can it be easily processed and repaired at the construction site according to the needs of the site? This is something that can be done easily and has a number of prevention points.
The special feature of the cover plate to protect the 4 sheet piles is that the construction can be done accurately and the anti-demolition system can prevent seawater from collapsing and turning into ashes. As shown in Table 1111J, all the fixtures with protruding bolts are fixed to the surface of the sheet pile, and the bolts of this fixture are used to secure the cover board, so there is no need to attach any parts to the steel sheet piles already installed on the quay wall. The cover plate can be attached to the steel sheet pile without the need for special processing. In addition, the second aspect of the present invention
In the invention, when attaching a plurality of cover plates to a steel sheet pile in which a plurality of cover plates are connected in parallel, the side ends of the adjacent cover plates are overlapped and the >IJj holes of the double-strength bar plates are installed. Pass it through the same bolt and put it through this bolt? Since it is designed to be fastened, all of the fixtures can be used in common for the accommodation of the cover plates and for the installation of the cover plates into the steel sheet piles, making it possible to simplify the structure.
