Abstract

(57) [Summary] (with amendments) [Purpose] The purpose is to align the upper end of the cleaning inspection tube with the ground surface with simple construction. [Structure] An upper end frame, which is a tapered cylinder whose diameter decreases upward, is fitted into the cleaning and inspection cylinder. [Effect] Since the upper end frame is a tapered cylindrical body whose diameter decreases upward, it can be tilted in a 360° direction along the slope of the ground surface GL when fitted to the cleaning/inspection tube.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention mainly relates to the upper end frame of the cleaning inspection opening that extends from the drainage basin to the ground surface. It is.

0002

[Conventional technology]

As shown in Figure 10, the pipe connections (2), (3), (4) extending from the side of the drainage basin (1) are connected to the main sewer pipes (6), (7) and branch pipes (8), and the cleaning inspection port (5) at the top is connected to The cleaning inspection tube (9) is connected, the cleaning inspection tube (9) opens to the ground surface GL, and the lid (10) is covered. It is worn.

0003 As shown in Fig. 10, the upper end surface (upper surface of the lid (10)) of the cleaning inspection cylinder (9) If it is not along the GL, one side of the upper end surface may protrude beyond the GL, or the other side may Bury it more. Therefore, in the past, the cleaning inspection tube (9) was temporarily buried and a line was drawn along the GL. The method used was to remove it again at the top and cut it along the line.

0004

[Problem that the idea aims to solve]

However, according to this conventional method, the cleaning inspection cylinder (9) is temporarily buried and aligned along the GL. After drawing a line, remove it again, cut it along the line, and then attach it again to the cleaning point. This would require the extremely troublesome work of backfilling the test tube (9).

[0005]

[Means to solve the problem]

The present invention, as a means to solve the above-mentioned conventional problems, The upper end frame (20) that is fitted into the A cleaning inspection consisting of a cylindrical body (21) and a flange (22) extended from the outer periphery of the cylindrical body (21). It provides the upper end frame (20) of the tube (19).

[0006]

[Effect]

The cylindrical body (21) of the upper end frame (20) of the cleaning and inspection tube (19) of the present invention has a diameter that decreases upward. Since it has a tapered shape, when it is fitted to the upper end of the cleaning inspection cylinder (19), the upper end frame (20) can be tilted in 360° direction. Therefore, the upper surface of the upper end frame (20) Tilt and adjust the upper end frame (20) so that it follows the slope of table GL in any direction. Rukoto can. Also, adjust the depth of fit of the upper end frame (20) to the cleaning inspection cylinder (19). The height of the upper surface of the upper end frame (20) can be adjusted by

[0007] After aligning the upper surface of the upper end frame (20) with the ground surface GL in this way, the cleaning inspection tube (19) When the upper end part is fully buried, the flange (22) of the upper end frame (20) will dig into the surrounding ground. Then, fix the upper end frame (20) so that it does not move.

[0008]

[Effect of the idea]

Therefore, in this invention, the upper end frame is simply tilted and its upper surface is aligned with the ground surface GL. The cleaning and inspection tube can be installed with extremely simple construction, and the height of the top surface of the upper end frame can also be adjusted. Extremely easy to adjust.

【Example】

To explain the present invention with reference to an embodiment shown in FIGS. 1 to 8, the upper end frame (20) a tapered cylindrical body (21) whose inner periphery decreases in diameter upward; and an outer cylindrical body (21). It consists of a flange (22) extending from the upper circumference, and a pad at the lower outer circumference of the cylinder (21). A packing groove (23) is formed in which the cylinder (25) is attached, and the outer periphery of the cylinder (21) is filled with water. A flat scale (24) is attached.

0010 As shown in Figure 3, the upper end frame (20) is connected to a cleaning and inspection tube (1 9) and the lid (26) is attached, but the outside of the cylinder body (21) of the cleaning and inspection cylinder (19) Since the periphery has a tapered shape that decreases in diameter toward the top, the inside of the cleaning inspection cylinder (19) A gap S is formed between the periphery and the outer periphery of the upper end frame (20), whereby the upper end frame (20) can be tilted in 360° directions. Therefore, what kind of surface GL is it? Even if the upper end frame (20) is tilted in the I can do that. Then, the packing (25) of the upper end frame (20) is tightly attached to the inner periphery of the cleaning inspection tube (19). to prevent the odor rising from inside the drainage basin into the cleaning inspection pipe (19) to leak to the outside world. To prevent.

[0011] The installation work of the cleaning and inspection tube (19) using the above-mentioned upper end frame (20) will be explained below. First, as shown in Figure 4, connect the cleaning inspection pipe (19) to a drainage basin (not shown), and The area near the top of the inspection tube (19) should be dug lower than the ground level GL. And the cleaning inspection tube (19) Fit the upper end frame (20) from the upper end. Adjust the fitting depth of the upper end frame (20) and attach it to the upper end frame (20). 0) Adjust the height of the top surface.

0012 Next, as shown in FIG. 5, the upper end frame (20) is tilted so that the upper surface of the upper end frame (20) is GL Adjust to match. At this time, the upper end frame (20) is temporarily fixed due to the friction of the packing (25). It will be done. Then concrete (27) is placed around it as shown in Figure 6. this When the flange (22) of the upper end frame (20) bites into the concrete (27), the upper end frame (20) is fixed in concrete (27). Or the upper end by soil as shown in Figure 7. The area around the frame (20) is hardened, but at this time, a notched annular spacer as shown in Figure 8 is placed in advance. (28) is cut to a predetermined width and fitted into the upper end frame (20). The spacer (28) is attached to the upper end frame (2 The upper end frame (20) is interposed between the flange (22) of 0) and the upper end of the cleaning inspection cylinder (19). Prevent it from falling into the removal cylinder (19).

[0013] Another embodiment of the present invention is shown in FIG. In this embodiment, the outside of the upper end frame (20) is A plurality of wedge grooves (29) are vertically provided around the circumference. Then clean the upper end frame (20). Fit the upper end of the removal inspection cylinder (19), align the upper surface of the upper end frame (20) with GL, and then A wedge is inserted between the upper end frame (20) and the cleaning inspection tube (19) via the wedge groove (29) of the frame (20). drive the screws (30) and temporarily fix the upper end frame (20) to the cleaning/inspection cylinder (19). Then the above Harden the area around the end frame (20) with concrete or soil.
