JPH0634798U - A frame for deeply filling a septic tank - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a capping frame for deep-filling that can easily adjust the burial depth of the septic tank according to the deep-filling height that changes depending on the installation conditions of the septic tank. [Structure] A spiral groove 8 is provided on the peripheral walls of the cylindrical outer cylinder 4 and the inner cylinder 5, and the inner cylinder 5 is inserted into the outer cylinder 4 by the spiral groove 8 to form the outer cylinder 4 or the inner cylinder 5. The capping frame for rotating the separable tank is arranged between the manhole frame 2 and the rising part 1 of the septic tank body so that the total length can be adjusted, and the capping frame for deeply burying the septic tank is adjusted. .

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cap raising frame used when deeply burying a septic tank.

[0002]

[Prior art]

 Conventionally, when it is necessary to bury the septic tank deeply depending on the installation conditions, a capsular frame 6 is inserted between the manhole cover 3 and the manhole frame 2 and the rising part 1 of the septic tank body as shown in FIG. Was there. When adjusting the height H of the cap raising frame 6, the cap raising frame was cut at an arbitrary position 7 as shown in FIG. 4 using a tool such as a saw and a sander. At this time, waste material 9 is produced. Alternatively, several kinds of capping frames with different heights H of the capping frame 6 are prepared in advance, and a capping frame of the required capping height is selected, or a plurality of capping frames are selected. It was used repeatedly.

[0003]

[Problems to be solved by the device]

 Since the installation work of the above-mentioned frame is carried out at the place where the septic tank is buried, noise and dust will be scattered around when cutting the frame to the required height, which is annoying. There is also a problem that the cutting work is difficult and the waste material must be disposed of. On the other hand, even if several types of capping frames with different heights are prepared, it may not always be possible to provide a matching capping frame, because the septic tanks have different deep filling heights. The present invention is a depth that can easily cope with the burial depth of each septic tank without cutting the above-mentioned raising frame or selecting or combining the required raising frames from several types. It is intended to provide a frame for filling a cap.

[0004]

[Means for Solving the Problems]

 According to the present invention, a spiral groove is provided on the peripheral walls of a cylindrical outer cylinder and an inner cylinder, the inner cylinder is inserted into the outer cylinder by the spiral groove, and the outer cylinder or the inner cylinder is rotated to adjust the total length. The present invention relates to a capping frame for deeply burying a septic tank, in which the enabled capsular frame is arranged between the manhole frame and the rising part of the septic tank main body to adjust the burial depth of the septic tank.

In the present invention, the material of the shade frame is not particularly limited as long as it can bear the weight of the manhole. Usually, plastic or metal is used. The fitting gap between the outer cylinder and the inner cylinder may be such that the inner cylinder can be rotationally moved within the outer cylinder. Either the outer cylinder or the inner cylinder may be rotated to adjust the entire length of the shade frame. In addition, between the cap raising frame and the manhole frame, or between the cap raising frame and the rising part of the septic tank main body, a material having lubricity is used to reduce friction between the rotating cap raising frame and the stationary body. You may interpose the plate-shaped body provided.

[0006]

【Example】

 Next, an embodiment of the present invention will be described. FIG. 2 is a sectional view showing a deep-filling shade raising frame according to an embodiment of the present invention, and FIG. 1 showing a state in which the deep-filling shade raising frame is arranged between a manhole and a septic tank. Reference numerals 4 and 5 are an outer cylinder and an inner cylinder made of plastic, respectively, and a spiral groove 8 is provided in each. Align the mutual spiral grooves 8, insert the inner cylinder 5 into the outer cylinder 4, and arrange between the manhole cover 3 and the manhole frame 2 and the rising portion 1 of the septic tank main body as shown in FIG. The outer cylinder 4 is rotated to raise or lower the entire length of the cap raising frame to adjust the burial depth of the septic tank.

[0007]

[Effect of device]

 According to the present invention, the burial depth of the purification tank can be easily adjusted according to the deep burial height that changes depending on the installation conditions of the septic tank, and the workability can be improved. Moreover, safety is improved because cutting work is unnecessary.
