Description

Technical Field

[0001] This utility model relates to the field of foundation pit engineering technology, and in particular to a rapid grouting device for anchor cable hole support. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the situation of nearby buildings, and waterproofing and drainage work should be carried out. For shallow excavations, slope protection can be used to stabilize the soil slope, and the slope should be determined according to relevant construction engineering regulations. For deeper excavations or those near buildings, excavation pit wall support methods, shotcrete wall protection methods, and even large excavation pits may use methods such as diaphragm walls and interlocking column-type bored piles to prevent the outer soil layer from collapsing. If there is no impact on nearby buildings, the well point method can be used to lower the groundwater level and open excavation with slope protection can be adopted. In cold regions, natural cold air freezing methods can be used for excavation, etc.

[0003] Depending on the soil characteristics, foundation pits can be classified into rock foundation pits, soft soil foundation pits, and hard soil foundation pits. For soft soil foundation pits, when using anchor cable support for reinforcement, anchor cable holes need to be opened at predetermined points in the soft soil foundation pit, and then grouting is performed inside the holes for reinforcement. However, most of the grouting devices currently used are transported from the concrete processing plant by concrete trucks to the site for single-point grouting operations inside the anchor cable holes. This method cannot fully mix the concrete raw materials on-site using a combination of high-pressure spraying and auxiliary wall scraping, resulting in incomplete mixing of the concrete raw materials, which affects the concrete support strength of the anchor cable holes. At the same time, it is also impossible to perform simultaneous grouting operations on multiple anchor cable holes, resulting in low efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing grouting devices, which mostly rely on concrete trucks to transport concrete from the concrete processing plant to the site for single-point grouting of anchor cable holes. This approach cannot fully mix the concrete raw materials on-site using a combination of high-pressure spraying and auxiliary wall scraping, nor can it perform simultaneous grouting operations on multiple anchor cable holes, resulting in low efficiency. Therefore, this invention proposes a rapid grouting device for anchor cable hole support.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rapid grouting device for anchor cable hole support includes a frame, a traction frame fixedly connected to the right side of the frame, a pin hole opened on the side of the traction frame away from the frame, a mixing box fixedly connected to the right side of the top of the frame, a feeding hopper connected to the front of the mixing box, a mixing mechanism provided in the inner cavity of the mixing box, and a grouting mechanism for use with the frame provided at the bottom of the mixing box.

[0006] Preferably, the mixing mechanism includes a drive motor, which is fixed to the side of the vehicle frame near the mixing box via a bracket. The output shaft of the drive motor is sequentially fixedly connected to a reducer, a connecting plate, and a hollow shaft from front to back. A mixing rack is fixedly connected to all four sides of the hollow shaft, and a scraper for cooperating with the inner wall of the mixing box is fixedly connected to the other side of the mixing rack. A booster pump is fixedly connected to the side of the connecting plate near the drive motor, and the air outlet of the booster pump is connected to an air pipe that communicates with and cooperates with the hollow shaft. Injection holes for cooperating with the mixing rack are opened on all four sides of the hollow shaft.

[0007] Preferably, the grouting mechanism includes a conveying pipe connected to the bottom of the mixing tank. A control valve and a booster pump are respectively connected to the side of the conveying pipe away from the mixing tank. The outlet of the booster pump is connected to a four-way connector, and the three outlets of the four-way connector are connected to threaded pipes. The other end of the three threaded pipes is connected to a grouting nozzle, and a manual valve is provided on the top of the grouting nozzle.

[0008] Preferably, the injection holes are distributed circumferentially along the transverse axis of the hollow shaft, and an anti-clogging mesh is fixedly connected to the inner wall of the injection holes.

[0009] Preferably, the mixing box has an annular slide rail on the side near the connecting plate, and the annular slide rail is slidably connected to a T-shaped slide frame that is fixedly matched with the connecting plate on all four sides.

[0010] Preferably, a feeding cover is snapped onto the side of the mixing box away from the feeding hopper, and F-type buckles are provided on all four sides of the feeding cover and the feeding hopper facing each other.

[0011] Preferably, the side of the vehicle frame away from the traction frame is provided with a sliding groove from front to back, and the front and rear sides of the vehicle frame near the sliding groove are provided with positioning reserved holes. The inner cavity of the sliding groove is slidably connected to a sliding seat that is fixedly matched with the grouting nozzle, and the front and rear sides of the sliding seat are threaded with positioning bolts that are matched with the positioning reserved holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This grouting device for anchor cable hole support, through the setting of a mixing mechanism, is driven by a drive motor and reducer, and a booster air pump provides a high-pressure air source. The combination of a connecting plate, hollow shaft, mixing frame, scraper strip, air pipe, and injection hole achieves thorough mixing of concrete raw materials on-site through a combination of high-pressure injection and auxiliary scraping. This ensures more complete mixing of the concrete raw materials, enhancing the concrete support strength of the anchor cable holes. The grouting mechanism, with a booster pump providing a high-pressure material delivery source, and the combination of a delivery pipe, four-way connector, threaded pipe, grouting nozzle, and manual valve, allows for simultaneous grouting of multiple anchor cable holes according to site requirements, improving the grouting efficiency of the anchor cable holes.

[0013] This grouting device for anchor cable hole support uses an anti-clogging net to even out the airflow from the injection hole and prevent concrete material from entering the hollow shaft through the injection hole. A ring slide rail and T-shaped carriage provide sliding support compensation for the connecting plate, improving its rotational stability. A feeding cover plate and F-shaped buckle facilitate quick sealing and opening of the feeding hopper. A chute, positioning pre-drilled holes, a sliding seat, and positioning bolts facilitate quick positioning of the three sets of grouting nozzles. Attached Figure Description
