Method for effectively plugging grouting hole
The invention discloses a method for effectively plugging a grouting hole. The method for effectively plugging a grouting hole comprises a pipe body with two open ends, the pipe body is provided with a horizontal part and a vertical part which are communicated with each other, the horizontal part is used for being inserted into the grouting hole, the vertical part is used for grouting material expansion and backflow, after grouting is completed, the horizontal part of the pipe body is inserted into the grouting hole, the vertical part of the pipe body faces upwards, after grouting material is initially set, whether grouting is full or not is judged through the vertical part of the pipe body, if the grouting is full, the pipe body is dismantled, and if not, grout supplementing is conducted. The method achieves the technical effects that: the grouting material can be prevented from overflowing after expansion, and the grouting material is full after shrinkage and backflow can be guaranteed. The method solves the problems that: in the related technology, the grouting material expands and flows out of the grouting hole without any hindrance due to the fact that hydration heat is generated in the grouting material solidification period of a prestress hole channel; and after the grouting material shrinks and flows back, the grouting material at the orifice part is not full.
本申请公开了一种一种用于有效封堵注浆孔的方法，该用于有效封堵注浆孔的方法包括：两端呈开口设置的管体，管体具有连通的水平部和垂直部，水平部用于插入注浆孔内，垂直部用于压浆料膨胀和回流，在压浆完成后，将管体的水平部插入注浆孔内，并使得管体的垂直部朝上，在压浆料初凝后，通过管体的垂直部判断注浆是否饱满，若饱满则拆除管体，否则进行补浆。本申请实现了既可防止压浆料膨胀后溢出，又可确保压浆料收缩回流后浆液饱满的技术效果，进而解决了相关技术中的预应力孔道在压浆料凝固期间，产生水化热，造成压浆料膨胀，从注浆孔无任何阻碍的流出来；压浆料收缩回流后，易造成孔口部分压浆料不饱满的问题。
