  CFG桩是水泥粉煤灰砾石桩的缩写。 它由水泥,粉煤灰,碎石,碎石或沙子和水制成,形成高粘结性桩,桩,桩和土壤垫层以及复合地基的地基处理方法。
  CFG pile is the abbreviation of cement fly ash gravel pile. It is made of cement, fly ash, crushed stone, crushed stone or sand and water to form high cohesive pile, pile, pile and soil cushion as well as foundation treatment method of composite foundation.
  CFG桩的应用范围:
  Application scope of CFG pile:
  CFG桩适用于支撑基础桩和基坑的支撑桩,也可以用作复合地基或防水帘。 适用的地层为混合填土,平原填土,塑料至软塑料粉质粉质,粉质粘土,软土,沙质粘土,粉砂,卵石层等。 也可以使用特殊的钻头进入强风化和中风化的岩层。 不受地下水位的限制,即使在潜水面以下的中间粗砂层中,由于连续的压力灌浆混凝土过程,也可以顺利地堆放。 它特别适用于复杂的地质条件,例如钻孔桩,沉管桩和静压桩,不适用于坍塌,膨胀和收缩,砂流,地层扰动,可湿陷的黄土。
  CFG pile is suitable for supporting foundation pile and foundation pit, and can also be used as composite foundation or waterproof curtain. The applicable stratum is mixed fill, plain fill, plastic to soft plastic silty, silty clay, soft soil, sandy clay, silty sand, pebble layer, etc. Special drills can also be used to enter strongly and moderately weathered rock layers. Without the limitation of groundwater level, even in the middle coarse sand layer below the phreatic water level, it can be stacked smoothly due to the continuous process of pressure grouting concrete. It is especially suitable for complicated geological conditions, such as bored pile, immersed pipe pile and static pressure pile, and it is not suitable for collapsing, expanding and contracting, sand flow, stratum disturbance and collapsible loess.
  CFG桩技术特点:
  Technical characteristics of CFG pile:
  1,适应性强,适用范围广。 它不受地下水位的限制。 它特别适用于复杂且难以处理的地质条件,例如软,硬夹层,流动的沙层和深层回填。
  1. It has strong adaptability and wide application range. It is not limited by the groundwater level. It is especially suitable for complex and difficult geological conditions, such as soft and hard interlayer, flowing sand layer and deep backfill.
  2,桩的质量好,桩端无虚土,不易出现桩头折断,缩颈,塌陷等质量问题。
  2. The quality of the pile is good, and there is no virtual soil at the end of the pile, so it is not easy to have quality problems such as breaking of the pile head, necking reduction, collapse, etc.
  3,高承载力,可充分发挥基础土的端承载力和摩擦阻力。 在施工过程中,水泥浆将桩端土和虚拟土渗透,压实和固结。 桩周围的土壤充满水泥浆,通过超流动混凝土渗透,压实并横向挤出,这提高了桩端的阻力,桩的侧向摩擦力大大提高了单桩的承载能力。
  3. High bearing capacity, which can give full play to the end bearing capacity and friction resistance of foundation soil. In the construction process, the cement slurry will penetrate, compact and consolidate the pile end soil and virtual soil. The soil around the pile is full of cement slurry. Through the infiltration of superfluid concrete, compaction and lateral extrusion, the resistance of the pile end is increased, and the lateral friction of the pile greatly improves the bearing capacity of the single pile.

  4,采用各种掺合料配制的超流动混凝土,摩擦系数低,流动性好,桩基分散性好,细石可以悬浮在混凝土中而不会下沉,钢筋笼易于放置,施工方便。
  4. The superfluid concrete made of various admixtures has low friction coefficient, good fluidity and good dispersion of pile foundation. The fine stone can be suspended in the concrete without sinking. The reinforcement cage is easy to place and the construction is convenient.
  5.桩身强度高。 可以根据设计要求配制超流动混凝土的强度等级。 绒头直径可以有选择地选择。 当前,存在各种桩直径,例如400、600、800、900、1000mm等,并且桩是柔性的。  。
  5. The pile body has high strength. The strength grade of superfluid concrete can be prepared according to the design requirements. Pile diameter can be selected selectively. At present, there are various pile diameters, such as 400, 600, 800, 900, 1000mm, etc., and the pile is flexible.
  6,可以紧跟其他建筑物的基础施工,而不影响原建筑物。
  6. It can follow the foundation construction of other buildings without affecting the original buildings.
  7.施工环境友好,噪音低,振动小,对人无干扰。 无需泥浆墙保护,无污水排放,无降水,并且建筑工地文明。
  7. The construction environment is friendly, the noise is low, the vibration is small, and there is no interference to people. No mud wall protection, no sewage discharge, no precipitation, and civilized construction site.
  8,施工效率高,速度快,综合经济指标好。
  8. High construction efficiency, high speed and good comprehensive economic index.
