Description

Technical Field

[0001] This utility model belongs to the field of grouting pushing technology and relates to a portable grouting pushing device. Background Technology

[0002] In numerous engineering fields such as civil engineering, tunnel engineering, and mining engineering, foundation reinforcement and seepage prevention are crucial for ensuring the safety, stability, and long-term performance of engineering structures. Grouting delivery devices inject grout with a specific ratio into the strata, filling pores and cracks, improving strata strength and permeability, thereby effectively solving engineering problems such as foundation settlement, tunnel leakage, and mine water inrush, and have been widely used. With the continuous expansion of the depth and scale of underground space development, engineering practice faces the severe challenge of ultra-deep borehole grouting under complex geological conditions.

[0003] 1. As the drilling depth increases significantly, the complex geological conditions such as uneven hardness, developed fractures, and high groundwater levels in the strata make it extremely difficult to accurately push monitoring instruments such as sensors to the bottom of the borehole.

[0004] 2. Traditional grouting pushers adopt a decentralized layout, with each component scattered, requiring a large construction site to house the equipment. In some space-constrained engineering sites, such as urban underground tunnels and narrow mine roadways, the layout and operation of the equipment are greatly limited. Utility Model Content

[0035] Specifically, such as Figure 2 As shown, it consists of a push rod 1, a first push tube 2, a second push tube unit 3, and a guide tube 4. The second push tube unit 3 includes several limiting push tubes, the number of which is determined by the drilling depth.

[0036] In this embodiment, the heads of several limiting push tubes are provided with annular bosses, and the outer walls of the annular bosses are provided with threads for threaded connection with the first push tube 2. The inner walls of the tails of the limiting push tubes are provided with threads for threaded connection with the next limiting push tube.

[0037] The first pushing tube 2 and several limiting pushing tubes are all hollow structures with bosses inside. One end of each boss is fixedly connected to the inner wall of the first pushing tube 2 and the limiting pushing tubes. It should be noted that a first through hole is provided within the boss, which communicates with the inner wall of the first pushing tube and the second pushing tube unit 3, for installing the guide tube 4. The size of the first through hole is adapted to the guide tube 4. In this embodiment, the first through hole is T-shaped; all other shapes are within the protection range.

Then, a set of guide tube pieces 4 are installed on the first through hole inside the first push tube 2. Using a tool or manually, the guide tube pieces 4 are pushed downwards to move them to the first through hole inside the limiting push tube. Figure 4 As shown, another set of guide tubes 4 is then installed on the first through hole inside the first push tube 2. It should be noted that the two sets of guide tubes 4 in the same direction are on the same horizontal line. Finally, the push rod 1 is inserted from the head of the first push tube 2 and passed to the tail of the limiting push tube, as shown. Figure 6 As shown.

[0048] Push rod 1, first push tube 2, limit push tube, and guide tube 4 can be made of ABS plastic tube or stainless steel. However, the same set of push devices must be made of the same material.

[0049] The method of using the portable grouting pushing device of this utility model is as follows:

[0050] Taking a limiting push tube as an example, firstly, the first push tube 2 and the limiting push tube are fixed together with a buckle. Then, a set of guide tube pieces 4 are installed on the first through hole inside the first push tube 2. Using a tool or manually, the guide tube pieces 4 are moved downwards to the first through hole inside the limiting push tube. Then, another set of guide tube pieces 4 is installed on the first through hole inside the first push tube 2. It should be noted that the two sets of guide tube pieces 4 in the same direction are on the same horizontal line. Finally, the push rod 1 is inserted from the head of the first push tube 2 and passed to the tail of the limiting push tube, as shown. Figure 6 As shown.

[0051] The method of use also includes: taking a limiting push tube as an example, firstly, a set of guide tube pieces 4 are installed on the first through hole of the limiting push tube, then another set of limiting push tubes is installed on the first push tube 2, and then the limiting push tube with guide tube pieces 4 is snapped together with the first push tube 2 with guide tube pieces 4. Then, the push rod 1 is inserted from the head of the first push tube 2 and passed to the tail of the limiting push tube.
