Abstract

PURPOSE: A four-part manhole is provided to install a manhole without reinstallation by controlling height rapidly, not to be shook by vibration, to let vehicles pass through except re-pavement or re-construction only and not to give time obstruction. CONSTITUTION: The four-part manhole is formed by assembling a manhole cover(10), inner steps(21), an internal tube(20) having a projection, an external tube(30) having a projection, and a cover for protecting the external tube(30) and projections to outer steps firmly. A vibration and noise control rubber packing is placed on the upper part of the internal tube(20) covered by the manhole cover and coupled firmly by a cam machinery to cover up tight.

Description

Four Parts Manhole Manufacture Method

According to the present invention, the manhole cover height is changed if the ground height is changed around the manhole after adjusting the whole or upper part only to adjust the height of the manhole when reconstructing the road pavement even if the conventional manhole is fixedly installed or separated in the field of construction works. Either dig out the entire manhole or use a dry mortar to smooth the gradient of the ground, or insert a control ring under the lid of the manhole to fit the manhole to the ground height. However, these methods dig a manhole or its surroundings and temporarily block traffic during reconstruction and training, resulting in traffic inconvenience.

Until now, the manhole is generally cast and its manufacturing method is dependent only on manual work. Therefore, the technical improvement and minimum weight suitable for mechanical mass production should be examined for mass production in the future. Although it is fixed, this height adjustment staircase is installed on the outside of the inner pipe and the inside of each of the adjustment screw type projections, so it is possible to adjust the height by raising the height by moving only the inner pipe or lowering the ground.

The height adjustment staircase where the exterior and the inner tube interlock with each other is inclined at the screw angle, and the inner tube and the exterior combined with each other are installed so that they cannot be separated from the last upper part of the stairs by installing projections so that they do not rotate any more at the top end of the stairs. Another feature is that it is a manhole that is easily tilted up and down just by turning, and the lid is also securely closed by the cam device because the staircase that is caught in adjusting the height is inclined and formed in a screw shape.

As shown in Figure 1, the handle 12, which is placed on the lid 10, which is the first part, is attached to the handle box 11, and the hook 12 is hooked up to a small ball (孔) at the top of the handle 12 to lift the handle 12. When the cam device 13 is locked by the cam device 13 formed at the bottom to prevent rust, and the cam device 13 having a triangular shape is erected, the shaft 14 connected to the same line descends and falls off the edge of the manhole to open the lid 10. On the contrary, when the handle 12 is pressed, the cam device 13 is pushed down so that the shaft 14 is pushed upward and contacts the edge so that the lid 10 is not moved.

The handle 12 shown in FIG. 1 is shaped when standing up and the shape when lying down is shown in FIG. 11 and shows that the shaft 14 goes down to the cam device 13 when the locking device shaft 14 is upright. When the handle 12 is laid down, the shaft is raised up due to the cam device 13, and thus the raising and lowering principle is made.

When assembling a manhole divided into four parts into one as shown in Figure 11 cut scene is formed, the exterior 30 is buried in the ground, so as to prevent the movement of the side fixing flange 33 to the side like a horn or bolt It can be tightened with a ball (34), and deeply mounted so that it can be fixed in the ground anyway. The height adjustment stairs (31) are also divided into six equal parts, so that every two halves form the steps, and the length is the height that the road pavement can be rebuilt. This figure explains why it should be.

2 shows a state in which the handle 12 is opened by opening the lid 10, which is the first part, and FIG. 3 shows the configuration of the inner tube 20, which is the second part, in which the locking shaft 14 connected to the handle 12 is located. Because it is locked at a long length, this is a problem when the shaft 14 is inserted into the inner tube 20, so that the gap 15 can be easily placed so that the shaft 14 enters the upper portion of the inner tube 20 so as to facilitate this. In order to make an inner tube staircase 21 on the outer wall, it is possible to adjust the height by arranging the inner tube staircase 21 and the inner tube stairway protrusions 22 by one by dividing the circle into six equal parts. If the rubber plate seat 23 is placed on the surface and the rubber packing is filled there, water does not enter and there is no fear of inundation even if it does not invade dust and water.

5 is the shape of the exterior portion 30, which is the third part, the flange 33 fixed to the ground is mounted in a circular shape, and the exterior stairs 31 are formed with only the projections 32 with the protrusions 32 to be sufficiently applied. The bolt hole 34 is placed on the flange 33 to help fix and the length should be made according to the specifications of the construction engine.

FIG. 6 is a partial cross-sectional perspective view illustrating an exterior stair 31 and a step protrusion 32 formed on an inner wall of the exterior 30.

FIG. 7 is an assembly drawing for explaining the reason why the exterior 30 and the cover are engaged, and FIG. 8 shows that the cover is divided into two.

9 and 10 are descriptions of the lid 10 and for the partial description of the cam device 13.

Therefore, covering the cover 40 is an essential part of protecting the steps and projections between the inner and outer pipes, and when the inner pipe 20 is raised, the second side to prevent impurities from entering between the stairs (21, 31). Between the two steps (21, 31) and the two adjustment projections (22, 32) placed between the inner tube (20) and the exterior (30) only when the cover (40), which is a portion, is covered with the cover fastening frame (41). It is a measure to prevent the stairs 21 and 31 and the protrusions 22 and 32 from being damaged because foreign substances do not enter.

Thus, the lid 10 and the inner tube 20 are in close contact with each other because only three portions are formed of stairs and protrusions, but there is a risk of foreign matter entering between the stairs 30 and the boss 20. In this case, since a single manhole is formed by winding a separate cover 40, this is called a four-portion manhole, which is a feature of this configuration.

According to the present invention described above, once installed, the height can be adjusted quickly without re-installation, and the mass production system is possible in the process, and when installed in concrete culverts, it is quickly installed and the height adjustment 4-position manhole is appropriately adjusted to the inside and the exterior. Next, cover the manhole cover and close it tightly with a cam device, and put it in the upper part of the inner tube to be combined with the vibration and noise prevention rubber boxing.

Cam-mounted manhole cover is an excellent manhole that the lock shaft is fixed to the bottom when the lock shaft is lowered by the action of the cam when the lock handle is upright, and the lock lock is bitten and the handle is locked at 90 degrees. will be.

The cover protects between the exterior and the inner tube from foreign matters, and the flange and bolt ball outside the exterior fix the manhole and fix only the exterior, so the inner tube rises and falls to make the height the same as the road surface without impacting the vehicle You will not receive.

Like this, if the four types are installed in the manhole according to the order in order, there will be no vibration or shaking, and the vehicle can pass immediately except for the moment of repaving or rebuilding the road, and it will not give the effect of time. Can be.
