[0025] When in use, first, after the first steel bar 22, the second steel bar 23 and the third steel bar 24 are woven, the template is attached to the first steel bar 22, the second steel bar 23 and the third steel bar 24, and concrete is poured to realize the formation of the second fixing plate 41, and the installation port 42 formed inside the second fixing plate 41 realizes the installation of the drain port, and the template is fixed to the side of the connecting mechanism 4. After the template is placed on the side of the connecting mechanism 4 to form the first fixing plate 11, the internal hollow of the first fixing plate 11 realizes the installation of the grouting mechanism 5, and the first fixing plate 11 with a hollow interior realizes grouting after the installation is completed, which is convenient for transportation and reduces the weight of the overall structure; then, during installation, if it is found that the steel bars of another wall to be installed do not correspond to the fixing rod 66 or the connection holes of another wall do not correspond during manufacturing, after determining the distance between each steel bar, slide a number of slide plates 65 according to the measured data to determine the position of the steel bars to be connected, and then fix the nuts 62 to ensure that the steel bars to be connected can be inserted into the fixing rod 6 6, the range of movement of the fixed cylinder 61 is between the two third steel bars 24; finally, after the position of the slide plate 65 and the position of the steel bars to be connected are determined, a plurality of springs 53 are inserted into the outer side of the fixing rod 66, and the fixing cover 52 is further threadedly connected to the fixing rod 66, and slurry is injected into the second fixing plate 41 to realize the casting of the grouting groove 12 with the second fixing plate 41 as the template. During grouting, a vibration pump can be placed in the vibration groove 54 to realize the sliding of the fixing rod 66 in the fixing cylinder 61, and the vibration page 55 fills the grouting hole 25 with mortar. When the mud is injected to the top position of the fixing cylinder 61, the injection of concrete is stopped. At this time, the fixing cover 52 and the spring 53 are removed for the convenience of the next use. The installation method of this method solves the problem of the mismatch of the connecting holes between the two walls on the one hand, and reduces the weight of the overall structure on the other hand, facilitates the installation of the transport box, and speeds up the construction speed. After the two units are installed, the template is attached to the junction of the two connecting units, and concrete is injected to fix the two units.

[0026] It should be noted that, taking the construction of a certain dam as an example, after the dam is filled at a certain height, the concrete core wall is constructed in the transition material area by the slotted concrete anti-seepage wall method. Before the wall concrete is poured, the grouting steel pipe for the curtain grouting construction under the wall is pre-buried. The upper part of the slotted concrete anti-seepage core wall can be connected with the lower slotted concrete core wall by steel bars. In other words, the lower part of the core wall is drilled and excavated, and the hole depth of tens of meters cannot be formed by the template process. After the construction of the lower core wall of the construction platform is completed, the core wall above the construction platform uses the original slotted concrete, and this part can use the template to explain the scope of use of the first and second embodiments.

[0027] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
