Description

DETAILED DESCRIPTION OF THE INVENTION In the case of underground concrete pipes, they are used for multiple purposes such as sewerage and electric wires, but conventionally, pipes on each side were mainly buried, which was uneconomical.

The present invention has been proposed in order to eliminate such drawbacks, and after a concrete pipe is laid, a mounting plate is installed that has through-holes at the upper and lower open ends of the concave notches arranged in rows along the upper and lower edges. Anchor plugs are set on the upper and lower surfaces of the inner wall of the concrete pipe at positions corresponding to the through holes of the mounting plate in the precast concrete bulkhead, and then the partition wall is carried into the concrete pipe and the mounting plate is inserted into the precast concrete bulkhead. The present invention relates to a method for attaching a partition wall to a concrete pipe, characterized in that a bolt inserted through a through hole is screwed onto the plug.

In the present invention, as described above, a precast concrete partition wall is used in which concave notches are arranged in a row on the upper and lower edges, and each of the concave notches is covered with a mounting plate having a through hole,
After laying the concrete pipe at a predetermined location, anchor plugs are set above and below the inner wall surface of the concrete pipe at positions corresponding to the through holes of the upper and lower mounting plates of the partition wall, and then the partition wall is carried into the concrete pipe. By using the recessed part of the bulkhead, insert the bolt into the through hole of the mounting plate from the concave notch, and screw it into the plug, so that the bulkhead can be easily installed.
Moreover, it can be installed accurately on concrete pipes.

As described above, according to the present invention, it is possible to easily attach a partition wall to a concrete pipe, and the inside of the concrete is divided into a plurality of pipes by the partition wall, which is economical and can be used for multiple purposes. The present invention has many advantages, such as the fact that a plurality of pipeline construction works can be completed only once.

The present invention will be described below with reference to the illustrated embodiments.

The enclosure is a precast concrete bulkhead with a rectangular main plate (1
), and a mounting plate (3) having a through hole (3α) is arranged in a row along the upper and lower edges of the partition wall, and a mounting plate (3) having a through hole (3α) is arranged so as to side the opening end surface of each of the recessed notches (2). It is anchored in the main version (1).

After the concrete pipe (B) is laid in a predetermined position, on the upper and lower surfaces of the inner circumferential wall of the intermediate pipe (B), at locations corresponding to the through holes (3a) of the mounting plate (3) of the partition wall (G). Set the concrete anchor plug (4). The same plug (
4) can be easily set on the inner wall surface of the concrete pipe (B) using commonly available commercially available all anchors and hole-in anchors (both are trade names).

Next, transport the bulkhead into the concrete pipe (B),
Insert the bolt (5) from the recessed part (2) into the through hole of the mounting plate (B) (
3α) and screwed onto the plug (4), fill mortar (6) between the concrete pipe (B) and the mounting plate (3) of the partition wall (4), and attach the partition wall to the concrete pipe. (B)
Attach to.

In addition, if necessary, invert (force concrete placement).

In the illustrated embodiment, the partition wall (A) is installed at the center of the concrete pipe (B), but by shifting it to one side, it can be adapted to various uses by making the left and right spatial areas of the pipe different. For example, when used in a separate sewage culvert, the amount of sewage flowing down is different from the amount of rainwater.

Although the present invention has been described above with reference to the illustrated embodiments, the present invention is, of course, not limited to these embodiments, and can be modified in various ways without departing from the spirit of the present invention. It is.
