Effective foundation reinforcement area judgment method based on EICP technology
The invention discloses an effective foundation reinforcement area judgment method based on an EICP technology, and the method comprises the steps: forming a reinforcement hole in a to-be-reinforced foundation, forming a plurality of detection holes in one side of the reinforcement hole, and inserting a rusted rod piece into the plurality of detection holes; then urea and urease are added into the reinforcing holes, so that the rusted rod piece reacts with an intermediate substance NH < 4 + > of a urease induced calcium carbonate deposition reaction in the detection holes; the method comprises the following steps of: reacting a rusted rod piece with urea, weighing the rusted rod piece before and after the reaction, calculating the amount of carbonate ion substances generated by hydrolyzing urea by using the corresponding urease by using a difference value between the initial mass Mj and the final mass Mj'of the rusted rod piece, and then calculating a point at which the amount of carbonate ion substances generated by hydrolyzing urea by using urease is zero by using an interpolation method, further, the corresponding effective foundation reinforcement distance based on the EICP process is obtained; the technical problem that when the EICP technology is implemented through an in-situ pouring method, the effective reinforcing area of the foundation to be reinforced is difficult to judge accurately, and therefore the positions of reinforcing holes are difficult to arrange accurately can be solved.
本发明公开了一种基于EICP工艺的有效地基加固区域判定方法，通过在待加固地基上开设加固孔，并在加固孔的一侧开设多个检测孔，并在多个检测孔中插入锈蚀杆件；然后在加固孔中加入尿素和脲酶，使锈蚀杆件在检测孔内与脲酶诱导碳酸钙沉积反应中间物质NH4+发生反应；并对反应前后的锈蚀杆件进行称重，利用锈蚀杆件的初始质量Mj和末态质量Mj′之间的差值计算出对应的脲酶水解尿素产生的碳酸根离子物质的量，然后利用插值法，计算出脲酶水解尿素产生的碳酸根离子物质的量为零的点，进而得出对应的基于EICP工艺的有效地基加固距离；本发明能够解决采用原位灌注法实施EICP工艺时，难以准确判断待加固地基的有效加固区域，从而难以准确的布置加固孔位置的技术问题。
