Invert construction apparatus in a manhole and invert construction method using the same

摘要

The present invention relates to a manhole invert construction device and a manhole invert construction method using the same, and more particularly, is formed in a semi-circular or U "shape inside the manhole to form a space in the space spaced from the manhole bottom and side Invert sheet and the front and rear shape of the invert sheet is a semi-circular shape of the same diameter as the inner periphery of the sewer pipe connected to one side of the manhole, or both ends of the semi-circular shape extending upwards to take the form of "U" Fixed posture of the inverted sheet, two or more fixed frame spaced in parallel to each other inside the manhole; improves the construction and increase the reuse rate of the device, and also the input and discharge of the device through the narrow manhole The present invention relates to a manhole invert construction device having an easy advantage and a manhole invert construction method using the same.
