Abstract

The invention relates to a construction method for straight manhole, which comprises the following steps: precasting a manhole, wherein the whole is precast by concrete, which is approximately in shape of a rectangle, and the precast manhole comprises a top cover plate; bracing and excavating a foundation pit according to size of the manhole, for forming a manhole foundation pit; after the manhole foundation pit is finished, grouting the concrete foundation; installing the precast manhole into the manhole foundation pit in way of hoisting via a hoist; and installing the top cover plate and backfilling. The construction method for straight manhole has advantages of short construction period, good tightness, obviously improved intensity, being more durable and capable of reducing probability of safe accidents.

Description

technical field

[0001] The invention relates to a construction method of a man well in communication pipeline engineering. Background technique

[0002] At present, most pipeline projects involve the construction of manholes. Manholes, also known as manholes, are through holes for line maintenance and maintenance personnel to enter and implement line maintenance and repair. In the communication pipeline project, the man well is used as a node of the pipeline for construction personnel to enter and exit, convenient for construction, maintenance, cleaning and repair, etc., and plays a decisive role in the long-term stability of communication quality. The dimensions of manholes are 1.8×1.4×1.8, 2.0×1.4×1.8, 2.4×1.4×1.8, etc. The traditional process of manhole construction mainly includes: foundation pit enclosure and foundation pit excavation, concrete foundation, brickwork and cement Mortar plastering, roof cover installation, backfilling, post-maintenance. The most common s...
