Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a corner drop receiving frame for blocking a water channel such as a sewage treatment plant.

[0002]

2. Description of the Related Art Conventionally, in order to block a water channel of a sewage treatment plant or the like, a plurality of corner cuts having an effective length of about 200 to 600 mm are inserted into receiving frames provided on both side walls in the middle of the water channel. Are stacked to form a waterway blocking wall. In such a conventional corner drop, as shown in FIG. 4, water-tight rubber plates 22 (seal materials) are attached to both sides of the corner drop 21 to secure water tightness, and a seal is formed between the corner plate 21 and the receiving frame 23. I am trying to do it.

[0003]

In the above prior art,
A high construction technique is required to prevent a gap from being formed between the rubber plates 22 attached to the upper and lower corner cuts 21, respectively, and watertightness cannot be secured depending on how the rubber plate 22 is attached to the corner cuts 21. Good waterproofness could not be obtained for the entire shielding wall. Accordingly, an object of the present invention is to provide a corner-dropping receiving frame structure that can be easily constructed while ensuring watertightness.

[0004]

Means for Solving the Problems In order to achieve the above object, the present invention has taken the following technical means. That is, the corner-dropping receiving frame structure of the present invention has a seal member attached to a receiving frame that receives the left and right end portions of the corner-dropping for closing the water channel, and the sealing material is formed of a plurality of corner-dropping piles stacked vertically. It is characterized by being formed in a long shape over the entire length in the vertical direction. According to the present invention, since the sealing material is continuous between the upper and lower corners, good watertightness is ensured, and the mounting accuracy of the sealing material does not necessarily have to be high. Therefore, according to the corner drop receiving frame structure of the present invention, the construction can be facilitated and speeded up.

[0005] In the above structure, the sealing member is formed in a substantially L-shaped cross section from the first band-shaped portion on the downstream front side of the corner drop and the second band-shaped portions on the left and right sides of the corner cut. It is recommended that According to this configuration, the second band-shaped portion may be fixed to the receiving frame or the side wall of the water channel with a fixing means such as an anchor, and the mounting operation can be easily performed from the side opening of the receiving frame, and the main sealing function is performed. It is not necessary to provide a mounting jig that may adversely affect water tightness in one belt-like portion, and it is possible to further improve water tightness.

The sealing member is formed in a substantially U-shaped cross section from a first band portion on the front side on the downstream side and the upstream side of the corner drop and a second band portion on the left and right sides of the corner drop. A configuration that assumes the same is also recommended. According to this configuration, the second band-shaped portion may be fixed to the receiving frame or the side wall of the water channel with a fixing means such as an anchor, and the mounting operation can be easily performed from the side opening of the receiving frame, and the main sealing function is performed. It is not necessary to provide a mounting jig that may adversely affect water tightness in one belt-like portion, and it is possible to further improve water tightness,
Even when the direction of flowing water in the waterway is not constant, watertightness can be ensured without re-squaring in any direction.

Furthermore, if a lip extending in the vertical direction is formed on the surface of the first band-shaped portion which comes into contact with the corner drop, such a lip is also continuous between the upper and lower corner drops, so that a further improvement is achieved. Water tightness can be improved. It is preferable that a plurality of the lips be provided in the left-right direction in order to improve watertightness.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. Receiving frame 2 of corner drop 1 (detour plate) according to the first embodiment of the present invention shown in FIGS. 1 and 2
The receiving frame 2 is provided in a channel closing device 4 provided at a middle or end of the channel 3 for blocking the channel 3.

The receiving frame 2 is provided in a vertical guide groove 6 formed on each of the left and right side walls 5 of the water channel 3. The receiving frame 2 in the illustrated example is made of a steel frame having a U-shaped cross section, and is attached and fixed to the side wall 5 by fixing means (not shown) such as an anchor. The receiving frame may be formed of a flat plate material attached to the inner surface of the guide groove 6, or may be formed of the guide groove 6 formed on the side wall 5.

The above-mentioned channel closing device 4 is provided with a corner drop 1 in which the left and right ends are inserted into the left and right receiving frames 2 from above. The corner drop 1 in the illustrated example is formed in a substantially rectangular parallelepiped shape. This corner drop 1 is made of natural wood, synthetic wood,
Various materials such as synthetic resin can be used, but it is preferable to use a corrosion-resistant plate material. As the corrosion-resistant sheet material, for example, a foam (eg, “Eslon Neo Lumber FFU” manufactured by Sekisui Chemical Co., Ltd.) made of a resin that becomes a hard foam and reinforced with long glass fibers may be used for bolts and nuts. Alternatively, each foam and the skeleton or the foams can be easily bonded by an adhesive.

As the resin to be used as the hard foam, a hard urethane resin, an unsaturated polyester resin or an epoxy resin may be used. As the fiber for reinforcing the resin, it is most recommended to use not only glass fiber but also inorganic fiber such as carbon fiber, metal fiber and ceramic fiber and organic fiber such as aromatic polyamide fiber. The form of the fiber is
The form of long fibers such as yarn, cloth, roving, roving cloth and cross mat is suitable, but if necessary, short fibers such as chips and middle fibers and hollow fillers such as shirasu balloons can be used in combination.

As shown in FIG. 1, the width L of the inner surface of the receiving frame 2 is
The thickness of the angle drop 1 is set to be larger than the thickness d of the angle drop 1 so that the angle drop 1 can be easily dropped in a state where there is no water in the water channel. After the plurality of corner cuts 1 have been dropped, it is preferable that the uppermost corner drop 1 is pressed downward by an appropriate pushing means (not shown) to secure watertightness between the top and bottom of the corner cut 1. As such a pushing means, a weight such as lead or a clamp device can be employed. In addition, in order to improve the watertightness between the upper and lower corner cuts 1, a sealing material covering substantially the entire length in the left-right direction can be provided on the upper surface or the lower surface of the corner cut 1.

The receiving frame 2 for receiving the left and right ends of the corner drop 1
A seal member 7 disposed in a gap between the corner drop 1 and the receiving frame 2 is attached. This sealing material 7 is formed in a long shape over the entire vertical direction of the plurality of corner traps 1 stacked vertically. The length of this sealing material 7 is
It is preferable to extend over the entire length of all corner cuts 1 to be inserted into, for example, in the case where water leakage occurs in some of the corner cuts 1 in the existing channel closing device, the portion is included. It is sufficient that at least two or more corner drops 1 have a length that covers the entire length in the vertical direction. In addition, as a material of the sealing material 7, an appropriate material such as soft rubber or hard rubber can be adopted.

A sealing material 7 shown in FIG. 1 is a first strip 8 which is disposed in front of the corner drop 1 and is long in the vertical direction.
And a second belt-like portion 9 which is long in the up-down direction and which is disposed on the left and right sides of the corner drop 1, is formed in a substantially L-shaped cross section.
Such a long sealing material 7 can be manufactured by extrusion molding, and a watertight structure of a plurality of corner cuts 1 can be obtained by a single sealing material 7, so that cost can be reduced and construction can be performed. The number of steps can be reduced. In the present invention, the sealing member 7 may be constituted only by the first strip.

When the first belt-shaped portion 8 is filled with water after the corner drop 1 is constructed, the corner drop 1 is pressed downstream by water pressure and pressed against the inner surface of the receiving frame 2. With this, a watertight structure can be obtained. Further, in the illustrated example, a plurality of lips 10 extending in the vertical direction are formed on the surface in contact with the corner drop 1 of the first band-shaped portion 9, so that further watertightness can be secured. The lip 10 may have any shape as long as it protrudes toward the corner drop 1.

The sealing member 7 in the illustrated example is attached to the receiving frame 2 by fixing the second belt-like portion 9 through the receiving frame 2 by fixing means 11 such as an anchor embedded in the side wall of the water channel. . Furthermore, in order to improve the mounting stability, the second band-shaped portion 9 is sandwiched between the presser plate 12 having the same width as the width of the second band-shaped portion 9 and the inner surface of the receiving frame 2,
The holding plate 12 is pressed and fixed to the receiving frame 2 by the fixing means 11. The holding plate 12 in the illustrated example employs a bracket having an L-shaped cross section to press and hold the end of the first band-shaped portion 8 against the receiving frame 2 as well, thereby preventing the first band-shaped portion 8 from being turned up. I have.

According to the corner drop receiving frame structure according to the first embodiment described above, the sealing material 7 is continuous over a plurality of corner cuts 1, so that good watertightness is ensured and the vertical corner drop is secured. 1 can prevent water leakage,
The installation of the seal member 7 for the plurality of corner cuts 1 is completed only by installing the anchor 11 from the side opening of the receiving frame 2, so that the number of construction steps can be reduced and the mounting position of the seal member 7 is slightly Even if the seal material 7 is shifted, the sealing material 7 is continuous, so that it is possible to secure reliable watertightness while being easy to construct. Furthermore, it can be easily installed on the existing receiving frame, and the water stopping performance of the existing waterway blocking device can be easily improved at low cost.
