Embodiment 1

[0031] Embodiment 1: as Figure 1~Figure 3 As shown in the figure, a fast plugging grouting nozzle for large-depth seepage water in a dam includes two grouting pipes 1 and a nozzle body connected to the lower part of the grouting pipe 1;

[0032] The upper part of each of the grouting pipes 1 is respectively provided with a switch 2, and the lower part is respectively provided with a one-way valve 10; the one-way valve 10 prevents leakage water from flowing back during the repair process;

[0033] The nozzle body includes a mixing chamber 3 and a pulping chamber 5, and the inside of the mixing chamber 3 is provided with a stirring member; the bottom of the mixing chamber 3 is connected with a pulping chamber 5 through a threaded pipe 4, and the pulping chamber 5 is conical. Shaped structure, the lower part of the slurry outlet chamber 5 is provided with a slurry discharge hole 6; the mixing chamber 3, the threaded pipe 4 and the inside of the slurry outlet chamber 5 are all co...

Embodiment 2

[0040] Embodiment 2: as Figure 4 Shown, a kind of embankment large-depth seepage water rapid plugging grouting method based on a kind of embankment large-depth seepage water rapid plugging grouting nozzle, comprises the following steps:

[0041] Step 1: Drill the grouting hole, and the drilling depth reaches the leakage position of the embankment;

[0042]Step 2: Connect one end of the two grouting pipes 1 to the nozzle body, and the other end to the grouting equipment;

[0043] Step 3: Deepen the sprinkler body to the leaking position of the embankment;

[0044] Step 4: The grouting equipment transports the two components in the high polymer used for repairing leakage to the nozzle body through two grouting pipes 1;

[0045] It should be noted that before this step, the high polymer used for repairing leakage is divided into grouting liquid containing two components in advance, and the above two components are injected into the two grouting pipes 1 through two grouting equ...

Abstract

The invention relates to a quick blocking grouting nozzle for large-depth water leakage of a dam. The quick blocking grouting nozzle comprises two grouting pipes and a nozzle body connected with the lower portions of the grouting pipes. A switch is arranged on the upper portion of each grouting pipe. The nozzle body comprises a mixing chamber and a slurry outlet chamber. A mixing piece is arrangedinside the mixing chamber. The lower portion of the mixing chamber is connected to the slurry outlet chamber through a threaded pipe. A slurry discharge hole is formed in the lower portion of the slurry outlet chamber. The invention further relates to a quick grouting method for large-depth water leakage of the dam. The quick grouting method comprises the steps that a grouting hole is drilled, and the drilling depth reaches the leakage position of the dam; one ends of the two grouting pipes are connected to the nozzle body, and the other ends of the grouting pipes are connected to grouting equipment; the nozzle body extends into the leakage position of the dam; and two components used in high polymer are transported to the nozzle body through the two corresponding grouting pipes and stirred and mixed and are discharged from the slurry discharge hole of the slurry outlet chamber, and gaps in the leakage position are quickly filled and blocked. By the adoption of the quick blocking grouting nozzle and grouting method for large-depth water leakage of the dam, quick grouting of the high polymer for emergency rescue of high-depth long-distance dam leakage can be realized.

Description

technical field [0001] The invention relates to the technical field of repair and reinforcement of water conservancy facilities, in particular to a rapid plugging grouting nozzle and a grouting method for large-depth seepage water in dykes and dams. Background technique [0002] Dike engineering is an important foundation of my country's flood control system. The total length of 410,000 kilometers of dikes has been built. However, the current dikes in my country are basically heightened and thickened on the previous basis. There are many hidden dangers, complex geological conditions, and frequent dangers during flood seasons. Once disasters occur, The impact is significant. Therefore, it is urgent to improve the level of emergency rescue technology and equipment for hidden embankment hazards in our country. The results of the survey of damage cases of dikes and dams (earth-rock dams) in the world show that damage and accidents caused by seepage stability account for more tha...
