Description

Technical Field

[0001] The present application relates to the technical field of water conservancy projects, and in particular to a grouting device for a protective dam. Background Art

[0002] Protective dam structures are often needed in water conservancy facilities to construct canals or clearly define the boundaries of rivers, lakes, etc., so that river protection belts can be repaired on the shore and clear roads and buildings can be planned. During the construction of the protective dam, it is generally necessary to first pile up a gravel slope, then cover it with a transition layer, and then fix it with a concrete pouring layer. The layers may be supplemented with seepage layers, etc. At the bottom edge of the dam, a vertical concrete curtain layer needs to be poured as a foundation to prevent the dam body from shifting, and also to prevent river water from penetrating through the shallow layer to the outside of the dam.

[0027] See also Figure 1 and Figure 2 The upper end of the grouting pipe 11 is fixedly connected with a connecting pipe 14, and a pressure gauge and other instrument auxiliary equipment can be installed on the upper end of the connecting pipe 14 for grouting work. The inside of the grouting pipe 11 is connected with a feeding pipe 15, and the grouting material can be easily introduced into the inside of the grouting pipe 11 through the provided feeding pipe 15.

[0028] See also Figure 4 and Figure 5 The lower fixing ring 3, the two upper fixing rings 2 and the connecting ring 1 are all made of stainless steel. The stainless steel material is used to increase the stability of the pipeline and prevent the water in the slurry from corroding the pipeline. The upper surface of the lower fixing ring 3 and each connecting ring 1 is fixedly connected with a plug plate 9, and the plug plate 9 can facilitate the connection between the connecting rings 1.

[0029] See also Figure 3 and Figure 4 A slot 10 is provided at the bottom of each upper fixing ring 2 and each connecting ring 1, and the inner wall of each slot 10 is plugged into the corresponding plug-in plate 9. The slot 10 can be plugged into the plug-in plate 9 to facilitate the connection between the connecting ring 1 and the upper fixing ring 2.

[0030] Please refer to 3. Figure 4 and Figure 5The lower fixing ring 3, the two upper fixing rings 2 and each connecting ring 1 are all provided with a socket 5, and a bolt 6 is inserted into each socket 5.

[0032] The implementation principle of a protective dam grouting device in the embodiment of the present application is as follows: when using the device, firstly, an appropriate number of connecting rings 1 are selected according to the length of the grouting hole, and then the lower fixing ring 3, the multiple connecting rings 1 and the upper fixing ring 2 are connected by connecting the bolts 6 and the connecting plate 7, and the connected pipeline is placed inside the grouting hole, and then the grouting pipe 11 is passed through the upper fixing ring 2 into the connected pipeline, and the slurry is allowed to enter the grouting pipe 11 through the feeding pipe 15, and the slurry will be discharged from the lower end of the grouting pipe 11, and at the same time, the pressure of the slurry will lift the lower fixing ring 3 and the scraper ring 1 3 rises, the scraper ring 13 clears the slurry on the inner wall of the lower fixing ring 3. When the lower fixing ring 3 drives the connecting ring 1 and the upper fixing ring 2 to rise and move out of the grouting hole, the corresponding connecting plate 7 is separated from the sliding groove 4 by removing the bolts 6 inside the upper fixing ring 2. At this time, the upper fixing ring 2 can be removed from both sides of the grouting pipe 11, and then the connecting ring 1 will be moved out of the grouting hole in turn. The bolts 6 and the connecting plate 7 are repeatedly removed to separate the connecting ring 1. When the lower fixing ring 3 is moved out of the grouting hole, the lower fixing ring 3 can be removed by moving it downward, so that the device can be conveniently disassembled according to needs.
