2. Establish temporary bench marks: temporary bench marks are often required for pipeline works, which should be set at a stable place that is not easy to be collided, and the spacing should not be more than 30 meters. The closure error of temporary benchmark shall meet the specified standards. 3. Trench excavation is mainly carried out by excavator, supplemented by manual bottom cleaning. Rainwater bucket connecting pipes and branch pipes are manually excavated. During excavation, pay attention to the change of soil quality, and support and enclosure the sections with signs of collapse. 4. Excavate by excavator until the elevation of the trench bottom is about 10cm. Do not excavate the reserved trench bottom soil, and then remove it manually to trim the trench bottom. Manually clean the tank, carefully check the soil at the bottom of the tank for disturbance, and if there is any disturbance, special treatment shall be carried out.

How is Jiaxing cement pipe made? First of all, the items needed for the production of cement pipes: steel bars, fine aggregate concrete, seam slots, steam chambers, reinforced shelves, cement pipe molds. Manufacturing process of cement pipe: first bind the reinforcement of cement pipe on a shelf, then wrap the reinforcement cage with a special mold, then pour fine aggregate concrete from a slot, seal the slot, then turn on the motor, make the rotary shaft in the cement pipe run to drive the cement pipe to rotate, make the concrete gradually dense through centrifugal operation, and then put it into the steam chamber for curing, Take it out when the strength of formwork removal is reached.

4. Excavator shall excavate to an elevation of about 10cm at the bottom of the trench. The soil at the bottom of the reserved trench shall not be excavated, and then it shall be removed manually to trim the trench bottom. Manually clean the trench, carefully check whether the soil at the bottom of the trench is disturbed, and if there is any, handle it. 5. On both sides of the trench and 1m above the bottom of the trench, elevation piles shall be set symmetrically, and elevation nails of equal height shall be nailed on them. The center line of the pipe channel and the elevation of the elevation pile shall be re measured before the bottom of the trench is reached and the pouring is leveled. 6. The height of soil stacking on one side of the trench edge shall not be more than 2m, and the distance from the trench edge shall not be less than 1m. The protection of underground pipelines for trench construction shall be disclosed to the relevant departments first to clarify the basic location of underground facilities. If necessary, sample holes shall be excavated first to find out the exact location, which is conducive to construction, and to ensure the safety of various embedded pipelines. During construction, support and protection measures shall be taken for exposed pipelines. 7. After the installation and connection construction, it is necessary to conduct a water discharge test, carefully observe for a period of time to check whether there is water seepage and leakage, and timely repair the problems found.

More rigorous and standardized measures and construction steps are also proposed for the cement pipeline according to the requirements: first, the surveying and setting out work should be in the charge of a full-time surveyor, and the construction of surveying and setting out records and check filing system should be strictly implemented, using calibrated instruments. According to the design drawings and pile handover records, check the bench marks, establish temporary bench marks, do a good job of protection, and conduct closed resurvey to control the elevation. Secondly, after the trench is excavated in sections, the elevation and elevation shall be reviewed in time to control the elevation of excavation, cushion and foundation surface. Squeeze and compact the stones, remove the soil, lay the reinforcement, erect the plank, and then pour the ground.

Before the cement pipe is laid in the ground, professionals should check whether the cement pipe is in good condition and whether there are cracks. Small cracks can be repaired on the spot. If large cracks affect the construction safety, return to the factory and replace the qualified cement pipe. The foundation for pipeline laying must be strictly controlled. The cement pipe manufacturer shall be responsible for the construction and the quality department shall supervise the construction. The problems must be checked layer by layer. The problems shall not be buried underground, otherwise, the quality will directly affect the later construction, and further maintenance will consume more human and material resources. When laying the pipeline, the manufacturer's construction team shall strictly follow the construction scheme, and shall not change the construction scheme or cut corners without authorization, otherwise the hidden dangers of engineering quality left after laying will be seriously affected.
