Concrete pre-embedded pile for soft foundation reinforcement
The invention discloses a concrete pre-embedded pile for soft foundation reinforcement, and belongs to the technical field of pre-embedded pile reinforcement. According to the concrete pre-embedded pile for soft foundation reinforcement, the scheme is that a pre-embedded pile is pre-embedded into soft soil, and concrete with a temperature is filled into a guide hole, so that concrete is in contactwith a cylindrical gasbag after entering an internal cavity, ammonium hydrogen carbonate in the cylindrical gasbag is heated to decompose and expand and gas pressure at the lower side of the cylindrical gasbag is increased, and therefore, a pre-sealed film is cracked; under return action of an elastic telescopic pole, a deformed rubber bag is extruded towards the outer side, and a contact circular plate is in continuous mutual friction with a spherical gasbag, so that calcium hydrogen carbonate in the spherical gasbag is heated to decompose, the spherical gasbag continuously expands through mutual friction between calcium hydrogen carbonate and quartz sand powder, and a contact area between turned-over deformed rubber bag and soil is increased, and therefore, sink of the pre-embedded pilecan be effectively relieved.
本发明公开了一种松软地基加固用混凝土预埋桩，属于预埋桩加固技术领域，一种松软地基加固用混凝土预埋桩，本方案通过将预埋桩预埋在松软泥土中，向导流孔内灌入带有温度的混凝土，使得混凝土进入到内置空腔内后与圆柱形气囊接触，使得圆柱形气囊内的碳酸氢铵粉末受热分解并膨胀，使得圆柱形气囊下侧的气压增大，从而使得预封闭膜裂开，并在弹性伸缩杆的复位作用下，使得形变橡胶囊朝着外侧挤压，通过接触圆板与球形气囊的持续相互摩擦，从而使得球形气囊内的碳酸氢钙受热分解，并通过其与石英砂粉末之间相互摩擦，使得球形气囊持续膨胀，提高形变橡胶囊翻转完毕后与土壤的接触面积，从而可以有效的缓解预埋桩的下沉。
