Collapsible loess strengthening method and strengthening piling machine for strengthening construction of collapsible loess
The invention discloses a collapsible loess strengthening method which comprises the following steps: adopting a vibratory hammer to drive a vibrating rod to vibrate, enabling loess around a vibratingpoint to be destroyed and densely recombined through action of an auxiliary medium to eliminate collapsibility of loess and form dense piles, and strengthening the dense piles and the surrounding loess to meet the strength requirement, wherein the auxiliary medium is a high-pressure gaseous phase medium and/or liquid phase medium. The collapsible loess strengthening method is convenient in construction and simple in operation, reflects the concept of environmental protection and energy conservation, reduces the construction cost, and has the following main advantages: the collapsible loess strengthening method does not use material, is low-carbon, environmentally-friendly, energy-saving, high in construction efficiency and low in construction cost; after construction, the collapsibility of loess is completely eliminated, the strength is high, next procedure can be immediately carried out without the waiting age, and the construction period is saved; and intelligent operation can be carried out, the labor cost is reduced, and the construction quality is ensured.
一种湿陷性黄土的加固方法，通过振动锤带动振动杆振动，并通过辅助介质的作用，使振点周围黄土的结构破坏并密实重组，使黄土的湿陷性消除，形成密实桩，对密实桩及周边黄土进行加固，以满足强度要求，所述辅助介质为高压的气相介质和/或液相介质。该方法施工方便、操作简单，体现了环保、节能的理念，降低了工程造价，其优点主要有：该施工方法不用材料，低碳、环保、节能；施工效率高，工程造价低；施工后，黄土的湿陷性完全消除，强度高，可以立即进行下一道工序，无需等待龄期，节约工期；可进行智能化操作，降低人工成本，保证施工质量。
