Abstract
Description
Technical Field
[0001] The utility model relates to a waterproof structure for a manhole of a communication pipeline, belonging to the technical field of communication optical cable construction. Background Art
[0002] When laying long-distance communication cables and optical fiber cables underground, a manhole must be installed every few dozen to a hundred meters for testing, laying, maintenance, diversion, and tapping. The manholes must have a certain degree of compressive strength and be leak-proof and water-free.
[0003] For example, Chinese patent publication CN204000937U discloses an integrated communication pipe manhole. A manhole cover with a through hole covers the manhole body. A cable bracket is mounted on the inner wall of the manhole body. A window is provided in the manhole wall, where a pipe base plate is installed. A manhole bottom is located below the manhole body. The bottom plane is slightly inclined toward the drain outlet. The manhole bottom with the drain outlet is connected to the municipal drainage well via a drain pipe. The entire manhole body is waterproofed with a waterproof coating. This design features a simple structure, strong applicability, simple construction, and can significantly shorten construction time.
[0004] However, the manholes for communication pipelines are generally buried underground, and the well bodies of the above manholes are only waterproofed with waterproof coatings. The waterproofing ability and waterproofing effect of the well bodies are relatively poor and need to be further improved. Utility Model Content
