PURPOSE: A polygonal manhole for a multiplex structure is provided to improve water-tightness, dimensional stability, and resistance to cracks. CONSTITUTION: A polygonal manhole for a multiplex structure comprises an inner diameter member(20), a core layer, a main body(100), a bottom body, and a top body. The inner diameter member has a stopping protrusion, a double fixing protrusion, a connecting groove, a sealing connection unit, a hanging protrusion, and a reinforcing protrusion. The core layer is formed between primary and secondary resins which coat the outer diameter of the inner diameter member. The main body is composed of a fiber coating layer. The bottom body is composed of resin concrete and is integrally connected to the bottom of the main body. The top body is composed of resin concrete and is integrally connected to the top of the main body. |
