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.
Details >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:
Details >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.
Details >Shanghai strong foundation soil strength composite pile technique by using proprietary cut pulverizer, combining with the intelligent control system, the soil cutting to pieces after injecting cement such as curing agent grout, according to a preset grouting quantity and for high speed cutting, cutting frequency mixing fully mixing, forming mud flow water, instant implants, precast pile formation strength composite pile
Details >Preparation before construction of vibrating immersed tube gravel pile & NBSP; The vibration-immersed tube gravel pile method is a method that uses the vibration-immersed tube to form holes, and adds hard particles to the tube, and forms the gravel pile after the pipe is pulled out and vibration-sealed to treat the foundation. The pile diameter can reach 1200mm, and the pile length can reach more than 40m.

The pile diameter can reach 1200mm, and the pile length can reach more than 40m. Vibration immersed tube gravel pile test pile construction
Details >The vibration-immersed tube scree pile method adopts the vibration-immersed tube to form holes, and adds hard particles to the tube, and forms the scree pile after pipe drawing and vibration compaction to treat the foundation. The pile diameter of Shanghai strong foundation large-diameter vibration-immersed tube scree pile can reach 1200mm, and the pile length can reach more than 40m.
Details >Considering the characteristics of the surrounding environment and the stress of the horizontal support system of this project, the principle of excavation of foundation pit supporting construction is as follows: 1. Before earthwork excavation of foundation pit supporting construction, detailed earthwork excavation construction organization design should be prepared. 2, foundation pit supporting construction earthwork excavation should strictly implement the principle of "stratification, segmentation, symmetry and balance".
Details >Quality assurance measures for biaxial mixing pile construction: 1. Hole setting out error is less than 50mm, pile vertical error is less than 1/100.
Details >1. Surveying and laying out according to the coordinate reference (control) point provided by the owner (or the general contractor), carry out the setting out positioning and engineering survey according to the design drawing, and make the permanent point and temporary point marks. The survey technology review list shall be completed after setting out and line, and the next procedure shall be carried out after the general contractor and supervision unit check and pass.
