Description

[Detailed Description of the Invention] The present invention relates to a side block whose height and inclination are adjustable for use in various sewage basins, manholes, and other underground structures.

This type of underground structure has a waterway buried underground at a predetermined slope, but because the height above the ground changes, it is necessary to adjust the length from the waterway or hall to the ground surface, or to adjust the cover installed on the ground surface. In order to adapt to the slope of the ground, especially roads, it is necessary to perform slope adjustment.
Conventionally, this posed the problem of having to use a special raising frame to adjust the height, and each time making a formwork and pouring mortar to make necessary adjustments. Therefore, there is a drawback that a large number of different types of raising frames for each side mass having different sizes are manufactured, and the period of storage and construction on the site is prolonged.

The present invention was made to solve the above-mentioned problem, and its purpose is to form grooves for separating and cutting directly on the circumferential surface of the side block, and to divide the side block with this groove to increase the height. To provide a side mass whose height and inclination can be adjusted and which can also be adjusted to correspond to the inclination of the ground surface by setting the separation groove at an inclination.

That is, in the present invention, around the cylindrical side mass 1,
a first separation groove 2 in a direction perpendicular to the central axis of the side block 1;
This is a side block whose height and inclination can be adjusted, and which is characterized in that a second separation groove 3 is provided in an inclined direction with respect to the central axis.

Detailed explanation will be given below with reference to the illustrated embodiments.
1 is a concrete side block having a cylindrical shape, 2 is a first separation groove with a substantially V-shaped cross section formed on the outer periphery of the side block in a direction perpendicular to the center axis L, and 3 is also formed in an inclined direction with respect to the center axis L. The former is mainly used for height adjustment, and the latter is used for inclination adjustment. Examples of these first and second separation grooves 2 and 3 are shown in FIGS. 5 to 9. Figures 5 to 7 show examples in which the separation grooves 2 (or 3) are provided on the outer periphery of the side mass 1 not continuously all the way around, but in a manner divided into 2, 3, or 4 parts, and Figure 8 is an example in which the separation grooves 2 (or 3) are provided on the outer periphery of the side mass 1. An example in which it is provided not only at the top or bottom of block 1 but also at the center, Figure 9 shows the first and second blocks.
An example in which the separation grooves 2 and 3 are provided to intersect is shown. Therefore, it is possible to form an optimal separation groove according to the material, structure, size, type, and use of the side block 1. still,
In the illustrated example, the side block 1 is not provided with reinforcing reinforcement, but it may be provided with separation grooves 2 and 3.
It is necessary to cut the reinforcing bars with a cutter or the like when dividing. As illustrated in FIG. 2, when two second separation grooves 3 are formed for one first separation groove 2, the angle of the upper end adjustment surface 1a of the side block 1 is adjusted to the setting of the second separation groove 3. When the inclination angle is θ, 0
The height can be adjusted continuously from 20 degrees to 20 degrees, and the height can be adjusted in three stages using three separate cutting parts 4 ₁ , 4 ₂ and 4 ₃ .

In each figure, 5 is a round frame-shaped adjustment block interposed between the lower block 1' and the upper block 1, and 6 is a disc-shaped bottom block that forms the bottom of the lower block 1'. 7 is an annular groove that supports the lower end of the lower side block 1' and fits in watertightly;
Reference numeral 7a denotes a brim portion that rises up on its outer periphery, and a similar configuration is also provided for the upper block 1 and the adjustment block 5. 8 is a four-part water collection groove 9 formed in the center of the upper surface of the bottom block 6
ridges with a, 9b, 9c and 9d, 10
a, 10b, 10c and 10d are each water collection groove 9a~
A connection port for connecting the conduit P to the side surface of the side block 1' corresponding to 9d, and a main connection port 1 corresponding to the main water collection groove 9a.
Other than 0a which is open, it is a thin closed part 10e that can be opened as needed. Further, the height and size of each of the water collecting grooves 9a and the connecting ports 10a are determined so that the flowing water can be transferred smoothly. 10f and 10g are step portions to which two types of large and small conduits can be selectively connected, 10h is a collar portion, and 11 is a lid receiving frame placed on the uppermost side block 1.

In the above configuration, for example, in order to install the lid receiving frame 11 adapted to the sloped ground G, the necessary installation ground is constructed in a hole excavated in the ground, and the bottom mass 6,
The lowest side block 1' and, if necessary, the adjustment block 5 are stacked one after another, and in order to adjust the inclination of the upper end adjustment surface 1a of the highest side block 1, the surplus portion ₄₁ is divided and adjusted with an appropriate second separation groove 3. Mold (Figure 4). If the slopes of the adjustment surface 1a of the side mass 1 and the ground G obtained by this are approximately equal, leave as is; if they are different, make fine adjustments using mortar, then place the lid holder frame 11 and continue the construction. finish. Incidentally, the joining portions of the stacked members from the bottom mass 6 to the lid receiving frame 11 may be filled with mortar or the like as appropriate.

Therefore, according to the present invention, the first separation groove 2 is provided around the side mass 1 and is perpendicular to the central axis L thereof, so that the difference in bulk with the ground surface of the underground structure can be reduced to the side mass 1.
If the ground surface is sloped, the side mass 1 can be partially divided with the second separation groove 3 inclined with respect to the side mass center axis L to adjust the inclination, and the inclination can be adjusted by dividing the side mass 1. As there is no need to use a raised frame or make adjustments by pouring mortar on site, the amount of materials prepared in addition to the side blocks is significantly reduced.
It has the effect of reducing setup time and shortening the construction period.
