Description

Safety diagnosis facility for checking sinking of manhole in water and sewage pipes {Check-up device for confirmed sinking of manhole water pipe}

The present invention relates to a safety diagnosis facility for checking the settlement of the manhole of the water supply and sewage pipe, and more specifically, is installed in the lower part of the manhole in the ground to check the settlement of the manhole substantially finely and at the same time to settle the manhole more than a predetermined scale. The present invention relates to a safety diagnostic facility for confirming settlement of manholes that can be prevented.

It is a well-known fact that manholes are buried in the middle of water and sewage pipes, gas pipes or various cables which are generally buried in the ground.

Such a manhole is provided at the upper part of the entrance to contact with the ground to enable the worker's access for maintenance of the cable or the like.

This manhole is a concrete structure, which may gradually sink into the ground due to its own weight. As a result, the sewage pipes connected to the manhole are also settled together, so that the manhole has a problem that is the primary reason for cracking or breakage of the sewage pipe. It would be desirable to provide a structure that can confirm subsidence.

The present invention is to solve the problems as described above, installed in the lower part of the manhole in the ground to substantially check the manhole sinking, and at the same time, the sinking of the sewage pipe manhole that can prevent the manhole sinking more than a predetermined scale in advance. The purpose is to provide a safety diagnostic facility for verification.

In order to achieve the above object, the present invention is formed in the bottom support ring plate which is a horizontal ring-shaped plate body in the ground, the fastening pipe having the inner screw portion is fixedly coupled to the left and right and front and rear sides of the lower support ring plate, the fastening tube center side A through hole is formed on the upper surface, and a plurality of flowing holes are formed on the upper surface of the lower support ring plate, and the outer thread portion corresponding to the inner screw portion is fastened and fixed to the lower surface, and has a through hole on the through extension line, and the upper end is opened. A vertical tube having vertical holes is formed on the body side of the lower support ring center side and vertically vertically. The tube is seated inside the vertical tube and has a corrugated portion stretched up and down on the outer circumferential surface thereof and protrudes downward through the through-hole and through-hole at the bottom. The outflow pipe protrudes and a corrugated tube is formed therein, and the antifreeze is filled therein. Is fastened to the bottom of the bolt which is fixed a circular plate having a vertically standing on the upper surface of the anchor bolt center formed of a circular plate to prevent separation of the pleated tube support frame and a work;

A flat bar having a cross bar, each end portion of which is positioned inward through a vertical pipe vertical hole of the lower support frame, respectively, and is mounted on the top surface of the corrugated tube;
