Description

Technical Field

[0001] The utility model relates to the field of water conservancy curtain grouting, in particular to a supporting template for water conservancy curtain grouting. Background Art

[0002] Curtain grouting is a grouting project that injects slurry into the cracks and pores of rock or soil to form a continuous water-blocking curtain to reduce seepage volume and lower seepage pressure. Curtain grouting uses grouting to construct an anti-seepage curtain in the rock or gravel foundation of the dam. The top of the curtain is connected to the concrete sluice floor or dam body, and the bottom is penetrated to a certain depth in the relatively impermeable rock layer to prevent or reduce the infiltration of groundwater in the foundation; working together with the drainage system located downstream, it can also reduce the uplift pressure of the seepage water flow on the dam.

[0003] In water conservancy projects, curtain grouting is an important anti-seepage technology. Water conservancy curtain grouting is mainly used to prevent water leakage and ensure the safe and stable operation of hydraulic structures. It forms a continuous anti-seepage curtain by injecting grouting materials such as cement slurry into the rock and soil, preventing groundwater infiltration and protecting dams, reservoirs and other water conservancy facilities. The height of traditional support formwork cannot be adjusted during construction, and the heights of workers are inconsistent. Taller workers have to bend over to work, while shorter workers have to lift their feet to construct, which not only increases the labor intensity of workers, but also increases the risks of workers during construction. Therefore, a support formwork for water conservancy curtain grouting is proposed to solve the above problems. Utility Model Content

The connecting plate 4 moves toward the top, driving the placement box 1 and the grouting gun 5 to move toward the top. When the grouting gun 5 is adjusted to a suitable position, the bolt 63 can be rotated at this time. The back of the bolt 63 will contact the front side of the adjusting sleeve 61. At this time, the height of the placement box 1 can be adjusted, and then the grouting gun 5 can be placed inside the placement box 1. At this time, the connecting rod 8 will enter the vertical groove 7, and then the front handle of the grouting gun 5 can be rotated up and down. At this time, the rotation of the handle will drive the grouting gun 5 and the connecting rod 8 to rotate up and down, so that the water conservancy curtain can be grouted by swinging up and down. At this time, the front handle of the grouting gun 5 can be pushed left and right. The rotation of the handle will drive the grouting gun 5 to swing left and right inside the horizontal groove 9, so that the water conservancy curtain can be grouted by swinging left and right.
