Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower construction technology, and in particular to a grouting device. Background Technology

[0002] Slope anchors are mainly used to reinforce soil and rock masses and prevent slope deformation and instability. They are commonly found in engineering fields such as mines, tunnels, and dams. The construction process of slope anchors generally includes: drilling and positioning, hole cleaning and anchor installation, and grouting and curing. During grouting, pressure needs to be controlled to ensure that the grout fills the soil densely, and the curing period should not be less than 7 days.

[0003] Existing grouting devices, such as the one disclosed in patent publication number CN222962902U, which improves grout fullness, include a connecting part and a conical part. The maximum outer diameter of the conical part is smaller than the diameter of the anchor bolt hole. During grouting, the grout exerts a reaction force on the conical part, causing the device to automatically retract. Grout is then replenished to the hole through a through-hole in the conical part, thereby improving the grout fullness. However, this device cannot meet the requirements for grouting pressure, grouting volume, and grouting uniformity under various working environments, resulting in poor grouting effect and reduced pull-out resistance and anchoring effect of the anchor bolt. Utility Model Content

[0004] The purpose of this invention is to provide a grouting device that better meets the pressure required during grouting and improves the grouting effect.

[0005] The technical solution of this utility model is: a grouting device, including a material cylinder, one end of which is provided with a feed inlet sealed by a cover plate, the other end of which is provided with a discharge outlet, a cover assembly installed at the end of the material cylinder near the feed inlet, the cover assembly being provided with a connecting rod that can extend and retract axially to abut against the cover plate, and an air inlet communicating with the inside of the material cylinder on the side wall.

[0006] In the above scheme, an air inlet is provided on the material cylinder to allow airflow, and the cover plate is sealed by a sealing assembly to generate the pressure required for grouting inside the material cylinder. The pressure increase ensures the uniformity of grouting, thereby improving the grouting effect and ensuring the pull-out resistance and anchoring quality of the anchor rod.

[0007] Preferably, the capping assembly includes a gantry frame, the lower end of which is connected to the material cylinder, and the upper end of which is equipped with the connecting rod.

[0008] Preferably, the gantry includes two fixed frames vertically connected to the diagonal of the material cylinder and a first support rod horizontally connected between the two fixed frames. The first support rod is located above the cover plate, and the connecting rod is installed on the first support rod.

[0009] Preferably, the gantry frame is provided with a connector, and the connecting rod is threadedly connected to the connector.

[0010] Preferably, the connecting rod is a screw rod, and the connecting rod is threadedly connected to the cover assembly.

[0011] Preferably, the lower end of the material cylinder is provided with a cone, and the bottom of the cone is provided with the discharge port.

[0012] Preferably, the discharge port is equipped with a valve.

[0013] Preferably, the cover plate is provided with a sealing ring that contacts the material cylinder.

[0014] Compared with related technologies, the beneficial effects of this utility model are as follows: I. The present invention provides an air inlet on the material cylinder that allows airflow to pass through, and uses a sealing assembly to seal the cover plate, so that the pressure required for grouting is generated inside the material cylinder. The pressure increase ensures the uniformity of grouting, thereby improving the grouting effect and ensuring the pull-out resistance and anchoring quality of the anchor rod. Second, the connecting rod acting on the cover plate is threaded, which makes operation simpler, the resistance to the cover plate more effective, and the locking effect better. Third, this utility model has a cone at the lower end of the material cylinder. The inclined surface on the cone facilitates the smooth flow of concrete and prevents concrete from accumulating in the material cylinder. Fourth, this utility model has a valve installed at the discharge port, which can control the amount of mortar and grouting according to the set amount of mortar. Attached Figure Description
