Maintenance means no steam curing tank. After the cement pipe is made on the cement pipe making machine, it is not necessary to open the grinding tool. Put the cement pipe mold and cement pipe outdoors for regular maintenance. Generally, after the cement pipe is made, it takes one day to carry out outdoor maintenance. The grinding tool can be opened the next day. After the mold is made, it also needs to carry out 4-6 days of regular maintenance, and full-time personnel should spray water on the cement pipe three times a day, The time of sprinkling is usually once in the morning, once in the afternoon and once at noon. The purpose of sprinkling is to maintain the environmental humidity of the cement pipe so that the concrete can gradually coagulate itself. The frequency of sprinkling can also be increased and reduced according to the environmental humidity of seasonal changes in weather conditions. But of course, there are more cement pipe molds required for maintenance.

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.

4) When mixing and sinking, start the rotary table of the deep mixing pile machine. When the speed of the mixing head is normal, the drill pipe can be mixed while sinking along the guide frame. The sinking speed can be adjusted by the gear, and the working current should not be greater than the rated value. 5) When the grout is mixed and lifted and sunk to the design depth, start the mortar pump, send the grout through the pipeline to the grout outlet of the mixing head, start the mixing pile machine and tighten the chain device after the grout is discharged, and lift the drill pipe while spraying and mixing according to the designed lifting speed (0.50~0.8m/min) to fully mix the grout and soil. 6) Repeat mixing and sinking. After the mixing bit is lifted to 500mm above the pile top, turn off the mortar pump, repeat mixing and sinking to the design depth, and the sinking speed shall be in accordance with the design requirements.
