Description

Manhole frame height and inclination control room {omit}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a valve chamber embedded in the ground for maintenance of a pipeline such as a sewer, a sewer, a gas pipe, and a water pipe, And a manhole frame on a sloping road, and it is possible to reduce the manufacturing cost and to shorten the construction time by improving the stability and workability by greatly simplifying the technical structure for achieving the slope. And a valve chamber capable of adjusting the inclination.

Generally, a pipe used for a sewer, a water pipe, a pipe used for a pipeline or a gas pipe, or a pipe used for a water intake or the like is buried in the ground. In order to control various kinds of fluid flowing in the pipe, (Hereinafter collectively referred to as "valve facilities") are equipped with valves, air valves, pressure reducing valves, ito valves, fire hydrants, flow meters, pumps, etc., As shown in FIG.

Such a valve chamber is provided with a manhole cover which can be accessed by an operator for maintenance of the valve facility. The manhole cover is installed through a manhole frame.

Most of the valve rooms are installed in the underground of the road for easy access to the vehicle or operator, and the manhole cover is exposed to the road. In this way, the manhole cover can be adjusted to the height of the road surface by adjusting the height from the valve chamber as required, and the manhole cover can be adjusted to the road surface slope in the inclined road.

A height adjustable valve chamber of Korean Patent Registration No. 10-0928469, a valve seat capable of height adjustment of Korean Registered Patent Publication No. 10-0949710 and a valve chamber having a height adjustment device of Korean Patent Registration No. 10-0988800 'Is a structure capable of adjusting the height of the manhole frame in the vertical direction from the valve chamber by using several height adjusting screws.

Korean Patent Laid-Open Publication No. 10-2010-0091478, in the case of a "valve seat of a simple installation type", two sheets of height-adjusting sheets having a slope are overlapped with each other and are flattened or inclined according to their laying directions, And the inclination can be adjusted.

Korean Patent Registration No. 10-0661049 discloses a manhole repair method using a manhole height adjusting device and a height adjusting method in which an adjusting bolt is installed on the side of a manhole cover to adjust a height and an inclination of a manhole cover for a manhole cover And the lower end of the adjustment bolt is supported by a manhole slab, which is a fixture, as a free end.

In the prior art, when the manhole cover is mounted on an inclined road at an inclined angle, the adjusting bolt is installed on the manhole cover so that the adjusting bolt is inclined at the same angle as the inclination of the manhole cover, There is a fatal defect that the manhole cover is caught from the road surface due to cutting or bending deformation of the adjusting bolt due to the load of the vehicle passing through the vehicle.

In the case of the "valve chamber capable of adjusting the inclination and height of the manhole" of Korean Patent Laid-Open Publication No. 10-2012-0016566, the weighted manhole frame is installed between the upper plate of the valve chamber body and the screw for adjusting the height and inclination The height of the manhole frame and the inclination of the manhole frame are adjusted by adjusting the screw.

First, in order to adjust the height or inclination of the manhole frame by adjusting the height of the screw, and to maintain the fixed state of the adjusted screw, it is necessary to unscrew and tighten the nut screwed on the lower part of the lower flange part of the manhole frame The nut is disposed at the lower flange portion of the manhole frame at the lower portion thereof, which makes it difficult to use a tool such as a spanner to unscrew and unscrew a nut at a construction site, thereby deteriorating workability and workability.

The lower end portion of the screw for adjusting the height is directly installed through the female thread portion formed on the upper surface plate of the valve chamber body and the upper end portion of the screw is connected to the weight hole of the manhole frame so that the load of the vehicle passing through the manhole cover is transmitted through the screw The screw is directly transmitted to the upper surface plate of the valve chamber main body, or the screw is deformed, or the upper surface plate of the valve chamber main body is affected, and leakage may occur at the screw connection portion with the upper surface plate.

On the other hand, in the case of the prior art, there are many components for controlling the height and inclination of the manhole, and there is a problem that the manufacturing cost is increased due to a lot of processing.

Therefore, in adjusting the height or inclination of the manhole frame, it is possible to perform the height and inclination adjustment function of the manhole frame through the height adjusting bolt, and by mounting the manhole frame through the height adjusting bolt adjusted in height or inclination There is still a need for a new technique to reduce installation costs and improve workability by completing installation.
