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. Then the block stones are pressed and compacted, the soil is removed, the reinforcement is laid, and the plank is erected Re pouring place.

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 piling on one side of the trench shall not be more than 2 meters, and the distance from the trench edge shall not be less than 1 meter. 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, facilitate construction, and ensure the safety of various embedded pipelines, Support protection measures shall be taken for exposed pipelines.

2、 Why the price of reinforced concrete cement pipe fluctuates. In economics, an important factor affecting the price is people's demand for this product. This is an important factor. When the demand is greater than the supply, the supply falls short of demand, and the price will naturally rise; But when the demand is less than the supply, when the supply exceeds the demand, the price will naturally decline, but the rise and decline will not be too high or too low. The higher the value, the higher the price. The lower the value, the lower the price. This supply is affected by many factors.

In the existing market, cast-in-place pipe sinking piles, precast concrete piles, bored cast-in-place piles and prestressed concrete pipe piles are widely used. Among the above pile types, prestressed concrete pipe piles are widely used due to the advantages of factory prefabrication, high concrete strength, convenient construction, and fast cycle, while cast-in-place pipe sinking piles are difficult to ensure their quality due to the need for on-site production, Due to serious environmental pollution, it is not suitable for geological conditions with thick soft soil layer, which is prone to necking, and the construction period is very long, so it has gradually been eliminated by the market. For example, the Guangdong Provincial Construction Commission has clearly stipulated that the use of immersed cast-in-place piles is not allowed, and the Zhejiang Provincial Department of Construction has also restricted the use of immersed cast-in-place piles.
