Floating mixing pile construction ship

The above water mixing pile construction ship (DCM ship) is a special engineering ship that assists the construction and installation of DCM pile. It is a highly automatic and intelligent ship that integrates cement storage, cement mixing, spiral conveying, underwater grouting and mixing in one pulp. It can stay underwater for 30. The deep cement mixing in the following places solidifies the deep seabed foundation, which plays an irreplaceable role in the reclamation of the sea.

Quality control measures of vibrating immersed tube gravel pile

Vibration-immersed tube crushed stone pile method is a method that uses vibration-immersed tube to form holes, and adds hard particles to the tube, and forms crushed stone pile to treat the foundation by pulling out the tube and vibration density. Large diameter vibrating immersed tube rubble pile & NBSP; The pile diameter can reach 1200mm, and the pile length can reach more than 40m.

Construction process of vibrating immersed tube gravel pile

The construction sequence of vibration-immersed tube gravel pile is as follows: clearing and leveling the site → laying out the hole position → crane entering the site → vibrator in place → vibrating soil extrusion into the hole → lifting the vibrator and pouring sand and stone into the hole → repeatedly vibrating and injecting sand and stone → piling to the hole opening → shifting to the next point. The key points of construction are as follows:

Construction quality control requirements of vibrating immersed tube gravel pile

Vibration gravel pile sinking pipe is under the effect of the vibration of the vibration hammer, the designed casing down by the provisions of the depth, the casing after the grave, casing surrounding soil compaction, and put the gravel to the tube, to make the rubble in the grave, segmented vibrating close-grained, form a larger diameter of the gravel pile, and will further compaction of soil between piles, after many times cycle into a complete both gravel pile. The piles form a composite foundation with the soil between them, which increases the bearing capacity of the foundation and prevents sand liquefaction.
