Intelligent grouting device and process for post-grouting of cast-in-place pile
The invention discloses an intelligent grouting device and technology for post-grouting of a cast-in-place pile, and belongs to the technical field of construction grouting. Comprising a limiting frame, an auxiliary half frame is slidably connected to the surface of the limiting frame, a driving mechanism is arranged on one side of the auxiliary half frame, a rectangular hole is formed in the position, located at the lower end of the driving mechanism, of one side of the auxiliary half frame, an air compressor is fixedly connected to the other side of the auxiliary half frame, and a matching mechanism is arranged at the top end of the auxiliary half frame; through the arrangement of the driving mechanism, the matching mechanism, the auxiliary semi-frame body and the air compressor, when the device works, a certain degree of separation cracks can be generated in a hole wall through impact force, then cement paste can permeate into a soil layer like a tree root state, and the cement paste rises layer by layer to separate the cracks and throw the cement paste; and the cement paste and the soil body are fully mixed and permeated to form a concrete column or a reinforcing body with higher strength, so that the bonding strength of the pile body and the foundation is obviously enhanced, and the bearing capacity and the stability of the foundation are improved.
一种灌注桩后注浆智能注浆装置及工艺，属于施工注浆技术领域。包括限制框架，限制框架的表面滑动连接有辅助半框体，辅助半框体的一侧设置有驱动机构，辅助半框体一侧处于驱动机构的下端开设有矩形孔洞，辅助半框体的另一侧固定连接有空压机，辅助半框体的顶端设置有配合机构，通过驱动机构、配合机构、辅助半框体和空压机的设置，使得装置在工作时，可以让洞壁内部通过冲击力产生一定程度的分离裂隙，随后使得水泥浆可以像树根状态渗透进土层，且逐层上升进行裂隙分离以及投放水泥浆，水泥浆与土体的充分混合和渗透，能够形成强度较高的混凝土柱或加固体，从而显著增强桩体与地基的结合强度，提高地基的承载力和稳定性。
