[0009]

【Example】

 The manhole device of the present invention is composed of a base sheet 1, an adjustment sheet 2, a fixed frame 3 having a cross hole, a cover 4, and a support block 6.

As shown in FIG. 1, the inside of the base sheet 1 is one accommodation space for accommodating the adjustment sheet 2, and a symmetric hole 11 is horizontally formed near the bottom end, and the bottom end is formed. The base sheet 1 is stably fixed on the debris by inserting fixing bolts 13 into flanges provided outwardly of the base, and the debris is placed around the base sheet 1 after the protective cover 12 is provided. Can be

A plurality of upper and lower support frames 21 are formed on the inner edge of the adjustment sheet 2, and a bolt block 22 is accommodated between the support frames 21, and adjustment bolts 23 inserted from the bottom end of the support frame 21. Pass through the bolt block 22. Separately, there is provided a fixed frame 3 having a cross hole 32 provided with a cross hole 32 through which the bolt 31 penetrates in a horizontal direction, which is combined under the adjustment sheet 2, and the bolt 31 is inserted after passing through the cross hole 32. It is inserted into the hole 11 of the base sheet 1.

The cover 4 is fitted to the upper end of the inner hole of the adjustment sheet 2.

The present invention has the above structure. The form of the large distance adjustment will be described first. Please refer to FIGS. A plurality of support frames 21 are provided on the inner edge of the adjustment sheet 2. At the time of adjustment, a bolt block 22 is accommodated between the support frames 21, and an adjustment bolt 23 is passed through. By rotating, the adjustment sheet 2 can be raised and lowered smoothly. In this way, when the drop between the installation position of the base sheet 1 and the road debris 5 is relatively large, the height of the adjustment sheet 2 is adjusted with the adjustment bolts 23 to adjust to the road surface, and the adjustment is completed by placing the cover 4. The large distance adjustment method of the present invention has been described above.

The present invention also provides another embodiment, that is, a small-distance adjustment mode, in which a fixed frame 3 with a cross hole is symmetrically combined with the bottom end of the adjustment sheet 2 and a bolt 31 is provided. Is inserted into the hole 11 through the cross hole 32 so that the adjustment sheet 2 is supported. The fixed frame 3 with a cross hole is provided with a cross hole 32, so that the distance adjustment operation is limited to the range of the cross hole 32. This adjustment operation is performed with the cover 4 opened in a situation where the head from the road is very large.

As shown in FIGS. 6 and 7, the support block 6 is a member placed on the bottom end of the adjustment sheet 2, and has a top stepped portion 61, which is connected to the adjustment sheet 2. The bottom end is fitted to the bottom end step-like portion 25.

When the top step 61 of the support block 6 is combined with the bottom step 25 of the adjustment sheet 2, the adjustment sheet 2 is stably positioned above the support block 6, and its inclination and tilt are adjusted. Position shift is prevented. Also, after the support block 6 is placed and positioned, even if the upper end surfaces of the adjustment sheet 2 and the cover 4 receive gravity due to the traffic of the vehicle, the support block 6 is completely supported by the support block 6, and the upper end surface is provided. The strength of the gravitational force received by the vehicle can be completely received, and the manhole device and the road surface can be maintained in a flat condition, and the seat supporting the cover does not collapse.

FIG. 8 shows another embodiment of the adjustment sheet 2 of the present invention. In this embodiment, the adjustment sheet 2 is formed to have a slope so that the adjustment sheet 2 is applied to a special situation, for example, a slope or a sloped road, so that a perfect leveling state with the road is ensured.

[0018]

[Effect of the invention]

 The manhole device according to the present invention provides a large distance adjustment, a small distance adjustment, and an inclination adjustment for a head that can occur between the manhole device and the road surface. It has the effect of securing the vehicle, and has the effect of increasing the safety of people and vehicles by leveling the entire road because the installation of the support block can receive heavy pressure.
