RAINWATER AND POLLUTED WATER PIPE HEIGHT CONTROL STRUCTURE OF MANHOLE

摘要

The present invention relates to a manhole connection right and sewage pipe height adjustment structure, and more specifically, to manufacture a hume pipe height adjustment frame on the side of the manhole separately and insert it at the end of the hume pipe and join and assemble the hume pipe height adjustment frame according to the height of the fume pipe. Construction is completed. In particular, it relates to the height adjustment structure of the manhole connecting well and sewage pipes that can precisely install the construction of the sewage / superior pipe and the manhole junction, prevent leaks and defects of the manhole, and reduce the construction date and construction cost by simple construction.;In particular, in the manhole structure that is installed only in the construction or road construction, the body of the manhole 1 is formed with a square groove 10 on the side, and a plurality of anchor bolts 12 outside the square groove 10 The watertight rubber gasket 14 is integrally formed with the watertight rubber gasket 14 and the fume pipe height adjusting frame 18 for preventing leakage in the square groove 10 of the manhole 1. (14) and the insertion groove 16 is formed in the center of the hume pipe height adjustment frame 18, the upper and lower ends of the hume pipe height adjustment frame 18 anchors in a state in which the straight composite member reinforcement 21 is in close contact with each other. The bolt 12 and the nut 14 are fixed to the anchor bolt 12, and the lattice-shaped composite member clip 23 is fixed to the center portion, and the insertion groove 16 formed at the center of the fume pipe height adjusting frame 18 is fixed. The fume pipe 30 is inserted and installed, so that the height can be adjusted according to the positional change of the fume pipe height adjusting frame 18 during construction. It shall be.
