Pipe network multi-section division pipe laying process

Abstract

The invention discloses a pipe network multi-section type labor division pipe laying process, relates to a municipal pipeline construction technology, and aims to solve the problems that the construction difficulty of people is increased today due to the fact that water is accumulated in a ditch in light rain weather, and after people wait for a sunny day and pump away water in the ditch, subsequent construction steps such as pipe arrangement can be started again, so that the construction cost is reduced. According to the technical scheme, the method is characterized by comprising the steps that firstly, a pipe network path is divided into a plurality of construction sections by adding 50-100 cm to the integral multiple length of a nodular cast iron pipe; 2, an initial ditch is dug in the earthwork at the initial position of the construction section, wherein the length of the initial ditch is 1.2-1.6 times that of the nodular cast iron pipe; and 3, the nodular cast iron pipe is placed in the initial ditch through an excavator, and gaps exist between the nodular cast iron pipe and the two ends of the initial ditch in the length direction. The working efficiency of pipe laying can be improved, pipe laying work can be carried out even in rainy days, and the situation that construction cannot be carried out due to slight weather influence is avoided.

Description

technical field [0001] The invention relates to municipal pipeline construction technology, more specifically, to a multi-section division-type pipe laying process of a pipe network. Background technique [0002] Rainwater and sewage diversion is a drainage system that separates rainwater and sewage, and transports them with a pipeline for discharge or subsequent treatment. The rainwater is directly discharged to the river through the rainwater pipe network, and the sewage is collected through the sewage pipe network and sent to the sewage treatment plant for treatment, so as to prevent the sewage from directly entering the river and causing pollution. Moreover, the collection, utilization and centralized management and discharge of rainwater can reduce the impact of water volume on the sewage treatment plant and ensure the treatment efficiency of the sewage treatment plant. [0003] Before rainwater and sewage diversion, it is necessary to set up rainwater pipes and sewage...

Problems solved by technology

[0004] However, once it encounters rainy weather, not to mention heavy rain, even in light rain, water accumulation in the ditch will increase the difficulty of construction. People wait for sunny days and drain the water in the ditch before they can start again. Start the subsequent construction steps such as pipe placement, and the work efficiency is low
