AI Technical Summary
When using geopolymer grouting to treat asphalt pavements, the grouting pipes lack an overflow prevention structure, resulting in inaccurate grouting volume. This can lead to insufficient or excessive grouting, affecting the repair effect and causing grout waste and pollution.
A grout overflow collection structure around the grouting hole was designed, which includes a grouting mechanism and a collection mechanism. The grouting volume is automatically controlled by a diversion block and an adjusting rod to prevent overflow and collect excess grout, ensuring sufficient grout in the grouting hole.
This allows for flexible control of the grouting volume, avoiding grout splashing and waste, ensuring sufficient grout inside the road surface, and improving the quality and efficiency of repair and treatment.

Abstract
Claims
1. A grout overflow collection structure around a grouting hole, characterized in that, include: The functional components, the collection cylinder (3) and the grip handle (4) are provided, wherein the functional components consist of a grouting mechanism (1) and a collection mechanism (2); The grouting mechanism (1) includes a grouting pipe (101) and a diversion block (102). The diversion block (102) is inserted into the inside of the grouting pipe (101). The collecting cylinder (3) is detachably fixedly installed on the side of the grouting pipe (101), and the holding handle (4) is fixedly installed on the other side of the grouting pipe (101). The collecting mechanism (2) includes a positioning block (201) and an adjusting rod (202). The positioning block (201) is inserted into the inside of the grouting pipe (101), and the adjusting rod (202) is rotatably connected to the top of the grouting pipe (101).
2. The slurry overflow collection structure around the grouting hole according to claim 1, characterized in that, The grouting pipe (101) is provided with a grout channel (111) inside, and the grout channel (111) is a "T" shaped channel. The grout channel (111) consists of a grout inlet channel (1111), a grouting channel (1112) and a grout distribution channel (1113). One end of the grout inlet channel (1111) is connected to the grout supply equipment through a pipe, and the top and bottom of the other end of the grout inlet channel (1111) are connected to the grout distribution channel (1113) and the grouting channel (1112) respectively.
3. The slurry overflow collection structure around the grouting hole according to claim 2, characterized in that, The bottom of the grouting pipe (101) is provided with a rubber plug (1012), and the cross-sectional shape of the rubber plug (1012) is trapezoidal.
4. The slurry overflow collection structure around the grouting hole according to claim 3, characterized in that, The diversion block (102) is located inside the slurry channel (1113), and the inner diameter of the slurry channel (1113) is larger than the inner diameter of the slurry channel (111).
5. The slurry overflow collection structure of claim 4, wherein, The grouting pipe (101) is provided with an overflow channel (1013) inside, and the two ends of the overflow channel (1013) are connected to the grouting channel (1113) and the collection cylinder (3) respectively.
6. The slurry overflow collection structure around the grouting hole according to claim 5, characterized in that, The bottom of the positioning block (201) is provided with a sealing top spring (2011), and the two ends of the sealing top spring (2011) abut against the inside of the positioning block (201) and the top of the grouting channel (1112) respectively. When no grouting operation is performed, under the action of the sealing top spring (2011), the diversion block (102) seals one end of the overflow channel (1013).
7. The slurry overflow collection structure around the grouting hole according to claim 6, characterized in that, The adjusting rod (202) has threads on the outside of its body, and the adjusting rod (202) is screwed into the inside of the positioning block (201) through the rod body threads.
