Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a device for treating the end of a discharge pipe that discharges moisture in the ground protected by a retaining wall to the outside.

(Prior art) When constructing a retaining wall, this type of drain pipe is usually installed on the wall together with concrete to be poured, and the end of the drain pipe protrudes regardless of the slope of the retaining wall. In many cases, they are allowed to do so. However, there are some that perform edge treatment, such as Utility Model Publication No. 58-3880,
No. 58-3881 etc. are publicly known.

(Technical Issues) If the end of the drain pipe is unrelated to the inclination of the retaining wall as in the past, the appearance will be impaired, and if it protrudes, the problem remains that the part may be damaged. The above-mentioned known example aims to improve this point, and connects a terminal pipe having an inclined end surface to the tip of a drain pipe, and fits the end pipe to the support frame so that the inclined end surface matches the slope of the retaining wall. do. However, even with this configuration, since the angle of inclination of the inclined end face is constant, it cannot be used if the inclination of the retaining wall changes. Therefore, several types of terminal tubes and support frames are required.

The present invention aims to eliminate this inconvenience by connecting the tip of the drain pipe and the mounting plate attached to the retaining wall using a mechanism that allows the angle to be changed and adjusted freely. An object of the present invention is to provide an end treatment device for a drain pipe for a retaining wall.

(Technical means) The purpose is to connect a drain pipe 1 whose base end communicates with the ground covered by the retaining wall R and whose distal end extends toward the outside of the retaining wall so that water can be drained, and the axis of the drain pipe. A guide plate 2 having an arcuate cross-sectional shape substantially orthogonal to the direction and provided at the tip of the drain pipe 1;
A sliding surface 3 that can be brought into surface contact with the retaining wall R is provided protruding from the back surface, and has an opening 4 communicating with the drain pipe 1 in a part of the sliding surface 3. A mounting plate 5 that is attached to the guide plate 2 and a connecting means 6 that connects the guide plate 2 and the sliding surface 3.
This can be achieved by a configuration comprising:

(Example) To explain with reference to the drawings below, drainage pipe 1
is for discharging moisture in the ground S protected by the retaining wall R to the outside of the retaining wall.The base end 8 opens on the ground S side of the constructed retaining wall R, and the tip end 9 opens outside the retaining wall. It is fixed within the retaining wall with a gentle slope towards the direction to allow drainage. 10 is a cylindrical portion 11 fitted into the base end portion 8
This is a locking member that has a locking plate 12 integrated with the water tank and is provided with an opening 13 for collecting water.

The guide plate 2 is connected to the distal end 9 of the drain pipe 1 through a cylindrical part 14 on the back, and is plate-shaped with an arcuate cross-section perpendicular to the axial direction of the drain pipe 1, and the illustrated arc has a concave outer surface. It becomes the guide surface 15 of the.

Therefore, the slide surface 3 is in a state of protruding toward the guide plate, and the guide surface 15 and the slide surface 3 are in equal contact with each other. The sliding surface 3 has a recess 7a in a direction perpendicular to the circumferential direction, which is the sliding direction.
A large number of protrusions 7 are provided at equal intervals and engage with the protrusions 7.
b are provided on the guide surface 15, and these are the guide plates 2 formed shorter than the slide surface 15.
angle fixing means 7 that slides in the circumferential direction and fixes each central axis at a predetermined angle that is diagonally shifted.
It consists of

Furthermore, the guide plate 2 and the slide surface 3 have approximately the same width, and are slidably engaged and connected by a connecting means 6 consisting of a side edge 6a of the guide plate 2 and a hook-shaped piece 6b that engages with the side edge 6a. It's dark. The opening 4 to be located at the front of the drain pipe 1 is formed to be elongated in the sliding direction of the sliding surface 3.

The mounting plate 5 is formed into a plate shape suitable for the appearance of the retaining wall, such as a circular, rectangular or diamond shape, and is provided with the sliding surface 3 so as to protrude from the rear side. A small hole 16 for fixing the mounting plate 5 to the formwork P is formed. Similar small hole 17
is also provided on the locking member 10. In addition, although the guide surface 15 is a concave surface and the slide surface 3 is a convex surface in the example, this may be reversed. Each component can be manufactured from synthetic resin.

(Function) The above-described drain pipe 1 and its end treatment device are installed using formwork when constructing the retaining wall R. That is, the locking member 10 is fixed to the inner formwork Q, the mounting plate 5 placed in a predetermined positional relationship thereto is fixed to the outer formwork P, and the base end 8 of the drain pipe 1 is fixed to the cylindrical part 11.
Next, the tip portions 9 are respectively engaged with the cylindrical portions 14 of the guide plate 2 to attach the guide plate to the formwork.

At this time, the mounting plate 5
The directions of the orthogonal axes of the guide plate 2 and the slide surface 3 do not match, but are shifted by an angle determined by the slope of the drain pipe and the slope of the retaining wall.
This can be absorbed by shifting the contact position in the sliding direction (Fig. 5). The above case deals with the inclination of the retaining wall R from the vertical plane, but the inclination in the horizontal plane can also be dealt with in the same way (6th
figure).

After demolding, the mounting plate 5 is aligned on the same plane as the outer surface of the retaining wall R, and thus becomes a part of the retaining wall. Regardless of the inclination of the mounting plate 5, its opening 4 is connected to the drain pipe 1, and the rear end of the drain pipe 1 is connected to the ground S, so the drainage performance is equivalent to or better than that of simply sticking a pipe. In good condition.

(Effects) Therefore, according to the present invention, smart end treatment can be performed which allows for installation and drainage without any problems even if the angle of the mounting plate 5 changes in the axial direction of the drainage pipe 1, and it can also directly accommodate changes in the rise angle of the retaining wall and bends in the horizontal plane, which is extremely convenient for construction, does not require the preparation of many different parts, is extremely rational, and has significant effects such as contributing to shortening the construction period.
