Embodiment Construction

[0062] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0063] Such as figure 1 As shown, it is a construction method of a drainage pipeline disclosed by the present invention, including S1 measurement setting out, S2 trench excavation, S3 foundation crushed stone cushion layer construction, S4 pipeline installation, S5 inspection well construction, S6 closed water test, S7 trench backfilling, S8 pipeline 2 reinforcement and other construction steps.

[0064] S1 measuring and setting out, release the pipe centerline and well position through the coordinate points and road centerline mileage piles, draw out the benchmark point, determine the excavation sideline of the foundation pit in the longitudinal direction of the pipeline, and measure the excavation depth to strengthen the maintenance of pile points; construction process Care should be taken to protect the measurement control points.

[0065] Such as figu...

Abstract

The invention relates to the technical field of drainage pipeline engineering, and particularly relates to a construction method of a drainage pipeline. The construction method of the drainage pipeline is characterized in that fixing structures, drainage ditches, water collecting wells and the like are additionally arranged on pipelines, and the problems that the pipelines float due to accumulatedwater in a groove, the pipeline butt joint installation, pipeline installation position and like are influenced can be effectively solved. Meanwhile, according to the additionally-arranged fixing structures, a C20 concrete wrapping layer outside the local pipeline can share the pressure of the pipelines from the upper portions of the pipelines, and the pressure resistance of the installed pipelines is improved, and moreover, the convex parts at the tops of the outer walls of the pipelines can facilitate aligned straight connection and installation between the adjacent pipelines; meanwhile, cover plates are matched with the convex parts at the tops of the outer walls of the pipelines, so that the pipelines can be prevented from moving and deviating after being connected, and the two sidesof the pipelines can be backfilled symmetrically and uniformly in the S7 groove backfilling.

Description

technical field [0001] The invention relates to the technical field of drainage pipeline engineering, in particular to a construction method for drainage pipelines. Background technique [0002] The Chinese patent with the authorized notification number CN103883810B discloses a steel mesh skeleton plastic composite pipe and its construction method, including a pipe body, a reinforced skeleton is inlaid in the middle of the pipe body, and adjacent pipe bodies are connected by connecting flanges at the connection positions; the plastic composite pipe Excavation of pipes through pipe trenches, on-site inspection of pipes and pipe fittings, butt joint of pipes and pipe fittings, electrofusion welding, cooling, lowering of pipes, installation and laying of pipes, strength and strict pressure tests, backfilling, project acceptance and other steps for construction. [0003] The above-mentioned existing technical solutions have the following defects: the material of the plastic comp...
