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.

The newly developed hollow square pile has completely overcome this disadvantage by combining centrifugal and prestressed technology with internal hollow. In the market, prestressed concrete pipe piles are used more frequently in industrial and civil buildings. They overcome the shortcomings of the previous pile types and have their own characteristics, but the disadvantages are also obvious: the appearance is smooth and round, especially when used as friction piles, the friction force with soil is small, and many projects have to use pipe piles with large outer diameter or simply use solid square piles, Increased project cost; The bending resistance of thin-walled pipe piles is poor, especially the shear resistance and tensile resistance of the pile body, which has buried hidden dangers in the foundation of the building

With the improvement of people's requirements for living environment, various construction measures have also raised the requirements accordingly. In the construction of drainage and sewage pipelines for urban construction, the requirements for the installation of cement pipelines have also been raised accordingly. This not only makes strict requirements on the quality and material of cement pipes, but also regulates the construction. Corresponding construction management specifications have also been formulated for the installation of cement pipelines. First of all, during installation, it is necessary to measure and set out first, and then dig trenches and earth according to the specifications of cement pipes. When laying the pipeline, the pipeline foundation construction shall be carried out first, and then the cement pipeline shall be cleaned inside the pipe, and then the concrete pouring inspection well and the anchor pouring shall be carried out. After these works are completed, the trench shall be backfilled as required.

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.

The shape of square pile is easier to develop a non welded quick connector, which can truly achieve all-weather construction, and construction is faster, which can avoid cracking of welded pile head in high groundwater level. 1) Positioning, centering and leveling of the pile driver. After the mixing pile position is placed, move the mixing pile driver to the designated pile position, centering and leveling (leveling with a level). 2) Adjust the verticality of the guide frame, and use a theodolite or plumb bob to control the verticality of the guide frame in both directions. According to the design and specification requirements, the verticality is less than 1.0% of the pile length. 3) The slurry is premixed in advance. While the deep mixer is premixing and sinking, the cement slurry is mixed in the background and put into the aggregate hopper before grouting. The cement grade 425 # ordinary silicate cement is used to mix the slurry, the water cement ratio is controlled in the range of 0.45~0.50, and the cement consumption per meter of deep mixing pile is not less than 50Kg according to the design requirements.
