Description

[Detailed Description of the Invention] The present invention relates to a water leakage prevention device used to treat water leakage from concrete poured joints, joints, etc. in tunnels, subways, etc.

Conventionally, this type of water leakage treatment involves installing a pair of base members on the surface of the concrete lining between the leakage points, etc., and bolting a cover member such as a steel plate or synthetic resin to the base members to cover the space between the base members. There were many things to do.

However, once this water leak prevention device is installed, it cannot be easily removed, so free lime, dissolved soil, water scale, etc. adhere to the cover member that serves as the water guide gutter, causing leakage to overflow and prevent it from achieving a complete water guide function. It was often hot.

Additionally, in cold regions, overflowing water would freeze, causing problems for trains and automobiles.

Therefore, the inventors of the present invention first attached a pair of base members to the surface of a structure so as to face each other, and provided these base members with engagement grooves whose entrance portions were smaller than the inside of the grooves, thereby forming the engagement grooves of the base members. proposed a water leakage prevention device in which the end of a cover member made of a single piece of rubber is fitted into the body, a wedge member is fitted into the engagement groove, and the cover member is held between the wedge member and the base member. (1981 Utility Model Application Publication No. 6560
issue) to resolve the above drawbacks.

The present invention is an improvement of the previously proposed invention, and its purpose is to further prevent water leakage and to firmly fit the cover member into the engagement groove.

Next, embodiments of the present invention will be described based on the drawings.

In the drawings, 1 and 2 are base members, 3 is a cover member, 4 is a reinforcing member for preventing deformation of the engagement groove, and 5 is a wedge member.

A pair of base members 1 and 2 are attached to the structure A by sandwiching the water leakage point B, but one base member 1 is attached to the attachment part 21 of the base member 1 and the other base member 2, and between both base members 1 and 2. A sheet-like cover member 3 that can be covered is made of the same material or a different material and is integrally continuous, and the cover member 3 is made to cover the mounting bolt hole 11 of the base member 1 on one base member 1. The sheet-like material is made of a rubber material or the like and extends in the direction of the other base member 2 facing each other, and an engaging portion 33 that easily engages with an engaging groove 22 of the base member 2, which will be described later, is provided at the extended end. and an engaging piece 34. The other base member 2 has a mounting part 21 having a bolt hole 24 in the side direction facing the one base member 1, which is continuous with the same material or a different material,
An engagement groove 22 smaller than the inside of the groove is provided at the entrance portion where one end of the cover member 3 is fitted on the outside. Note that 23 is a concave portion for engaging the engaging piece 34, and 25 is an uneven portion for adapting to unevenness on the surface of the structure.

The reinforcing member 4 for preventing deformation of the engagement groove has a shape such that it comes into close contact with the side of the other base member 2 facing the one base member 1, that is, in this embodiment,
Since the side portion of the other base member 2 has a tapered shape, the bolt hole 42 is formed into a tapered shape 41 that matches the tapered shape, and is located in the bolt hole 24 of the mounting portion 21.
is drilled. This member can be used as it is in the gap when the base member 1 and the cover member 3 connected thereto cover the base member 1. The wedge member 5 has a shape that can be driven into the engagement groove 22 of another base member 2 when the end of the cover member 3 is fitted into the engagement groove 22 of the other base member 2. Note that the reinforcing member 4 may be formed by being embedded in the mounting portions of the base members 1 and 2. Furthermore, it goes without saying that the shapes of the reinforcing members adjacent to the mounting portions of the base members 1 and 2 may be different from each other.

The present invention is composed of the various parts as described above, and has the following configuration.

That is, a pair of base members 1 and 2 are attached to the surfaces of structures A and A with water leakage point B in between, and one base member 1 is attached with an attachment portion 11 of the base member,
21 and a sheet-like cover member 3 that can cover between both base members 1 and 2 is continuous, and the other base member 2 has an attachment part 21 in the side direction facing one base member 1. An engaging groove 22 is provided on the outside with an entrance portion smaller than the inside of the groove, and a reinforcing member 4 for preventing deformation of the engaging groove is installed in the side attachment part 21 facing one base member 1. After fitting the end of the cover member 3 that is continuous with the base member 1 into the engagement groove 22 of the other base member 2, the wedge member 5 is fitted to that part, and one end of the cover member 3 is inserted into the engagement groove 22 of the other base member 2. The water leakage prevention device is configured to be held in the engagement groove 22 by the member 5. Here, the reinforcing member 4 is placed on both the base members 1 and 2, and the bolts 6 are inserted into the respective bolt holes 11, 42 and 25, 42 to be fixed to the structure. Note that the base members 1, 2 and the cover member 3 are usually made of rubber, and the reinforcing member 4 for preventing deformation of the engagement groove is made of a material that is more rigid than the base member due to its nature, such as hard synthetic resin steel.

Since the present invention is constructed as described above, it can be easily attached to the required part of the structure as needed, and has good workability.In addition, the base member of the cover member can be attached and detached by attaching and detaching the wedge member. Since the cover member is free, it is easy to clean and repair the inside of the water guide gutter formed by the cover member.

Particularly, in the present invention, by connecting the reinforcing member for preventing deformation of the engagement groove, it is possible to prevent the entrance portion of the engagement groove from widening when the cover member is pulled by water pressure, etc. It can prevent unnecessary removal from the pipe and can withstand the water pressure inside the water guide gutter. Further, the fact that one base member and the cover member are continuous also contributes to this effect. Furthermore, by having the cover member cover the attachment part, there is also an effect that water leakage from the attachment part can be guided to the water guide gutter.
