Pulse reaming device and pulse reaming construction method
The invention relates to the technical field related to building construction, and aims to provide a pulse reaming device and a pulse reaming construction method, the pulse reaming construction method can meet the reaming requirement of any position of a drilled hole, is low in use cost and small in hole collapse risk, is particularly suitable for reaming construction of soft soil and mucky soil, and can meet the requirement of reaming of any position of the drilled hole. The construction safety is good, and the engineering quality is high. The pulse reaming construction method comprises the following steps: drilling a formed hole at a hole opening position to form a drilled hole; concrete is poured into the drill holes; and performing pulse reaming by using a pulse reaming device to form a reaming section. The pulse reaming device comprises a protective cylinder and at least one electrode assembly, each electrode assembly comprises a backflow cylinder, a positive electrode and a negative electrode, the positive electrodes and the negative electrodes are arranged at intervals, the positive electrodes and the negative electrodes are arranged below the protective cylinders, and the positive electrodes and the negative electrodes are at least partially arranged in the backflow cylinders. The method solves the problems that an existing bottom expanding construction mode adopts a construction mode of first expanding and then pouring, the drilling collapse risk exists, and the construction safety is affected.
本发明涉及建筑施工相关技术领域，其目的是提供一种脉冲扩孔装置及脉冲扩孔施工方法，这种脉冲扩孔施工方法，能满足钻孔任意位置扩孔的需求、使用成本较低，而且塌孔风险小，特别适用于软土、淤泥质土的扩孔施工，施工安全性好、工程质量高。该脉冲扩孔施工方法，包括：在开孔位置钻进成孔，形成钻孔；向钻孔内灌注混凝土；利用脉冲扩孔装置进行脉冲扩孔，形成扩孔段。脉冲扩孔装置包括护筒和至少一组电极组件，电极组件包括回流筒以及间隔设置的正电极和负电极，正电极和负电极置于护筒的下方，并且正电极和负电极至少部分设置在回流筒内。本发明解决了现有扩底施工方式采用先扩再灌的施工方式，存在钻孔塌陷风险、影响施工安全的问题。
