Collapsible loess foundation reinforcement method
The embodiment of the invention provides a collapsible loess foundation reinforcement method. The collapsible loess foundation reinforcement method comprises the following steps that a vibration rod is vertically positioned above a collapsible loess foundation to be reinforced; the vibration rod is controlled to vibrate according to the preset vibration frequency, and meanwhile, high-pressure gasinjection is started to enable high-pressure gas to inject from the lower part of the vibration rod to the transverse direction; the vibration rod sinks in the vibration process, the high-pressure gascuts a soil mass, and the soil mass structure is broken; and after the vibration rod sinks to the preset depth, high-pressure gas injection is closed, and the vibration of the vibration rod is kept to densely vibrate to reinforce the loess foundation. According to the collapsible loess foundation reinforcement method, the technical problems of low efficiency and poor reinforcing effect of a traditional vibration rod dense method being applied to the collapsible loess foundation reinforcement construction are solved.
本申请实施例提供了一种湿陷性黄土地基加固方法，包括如下步骤：将振动杆竖向定位于待加固的湿陷性黄土地基之上；控制所述振动杆按照预设振动频率进行振动，且同时开启高压气体注入使所述高压气体从所述振动杆的下部向横向方向喷射；其中，所述振动杆在振动过程中下沉，所述高压气体切割土体，破坏土体结构；在所述振动杆下沉到达预设深度后，关闭高压气体注入，并保持所述振动杆的振动以振动密实加固黄土地基。本申请实施例解决了传统的振杆密实法应用在湿陷性黄土地基加固施工中效率低，加固效果差的技术问题。
