Abstract
The invention discloses a laying construction method of a drainage pipeline for sewage disposal, relates to the technical field of sewage discharge, and in particular relates to a laying constructionmethod of the drainage pipeline for sewage disposal. The method comprises the following steps: S1, excavating a foundation pit, namely, excavating the foundation pit for laying the drainage pipeline on the ground through which sewage flows, wherein the opening of the foundation pit faces upwards, and the side wall of the foundation pit is perpendicular to the bottom surface of the foundation pit;and S2, mounting bases, namely, placing the bases used for supporting the drainage pipeline in the foundation pit excavated in the step S1, wherein a plurality of bases are placed, and every two adjacent bases are fixed to the bottom face of the foundation pit at equal intervals. A guide plate is fixed to the top end of each tray, each guide plate is arranged to be of a square-block-shaped flat plate structure, the top end of each guide plate is erected on the ground on the other side of the foundation pit, so that the drainage pipeline can roll to the side wall edge of the foundation pit conveniently, and the drainage pipeline rolls into the trays through guiding of the guide plates.
Description
technical field [0001] The invention relates to the technical field of sewage discharge, in particular to a drainage pipe laying construction method for sewage treatment. Background technique [0002] Sewage refers to the discharged water from life and production that is polluted to a certain extent, and the water that has lost its original function is called sewage for short. It is mainly the water after daily use, which contains more organic matter and is easier to treat. The existing, whether it is rural or urban, has a huge amount of domestic wastewater discharged every day. For urban or rural densely populated places, wastewater is difficult to It is directly used, so it is necessary to use drainage pipes to transport wastewater from densely populated places to another, so as to facilitate the unified purification and utilization of wastewater. [0003] Drainage pipeline refers to the system composed of pipes and channels and their ancillary facilities for collecting a...
