Is the construction of the water supply steel pipe a telescopic device?
At the same time in the ditch earthwork construction of the canal, in a timely manner in the construction preparation, construction machinery and personnel enter in time, officials familiar with the construction drawings and the requirements of the technical scheme, pipes and fittings in finished products into the factory inspection, once the pipe forming, timely pipe installation work.
After completion of the individual project, the pipe top elevation and control point coordinate shall be measured before completion of the trench backfill, and the completed measurement result sheet shall be drawn, and the completed drawing shall be drawn accordingly.
When building management personnel to operate, strict inspection, selection of qualified brick factory with the same specification, on the masonry staggered, a brick, mortar and uniform horizontal mortar joint concave mortar, should take 5--8cm, wells and vertical mortar joint width not less than 5mm, while laying on the edge of a mud brick rub a squeeze, the slit into pulp, necking, measuring layers with a ruler, each layer in size, surrounded by flavours of not more than 3cm, three flavours of not more than 4cm, to ensure the quality.
The trench excavation method should be carried out before the investigation and study, fully understand the channel section of the soil, underground water, underground structures, underground trench near building and construction environment, find the problem timely contact with the construction unit, research on treatment measures. In order to prevent over excavation, the groove should be laid out before excavation, and the excavated layer shall be excavated at intervals according to the opening slope, and the excavation depth shall be measured at any time.
The pipe line survey shall be carried out in accordance with the coordinates of the pipe line control points. In order to master the control points of the canal well, the permanent reference piles shall be introduced and set up in the engineering site, and properly maintained, and the project shall be submitted to the owner after completion of the project. After the above work, please check the line of supervision personnel, confirm the ditch excavation work.
