The invention discloses an anti-seepage grouting device and technology for a cast-in-place pile, and particularly relates to the technical field of grouting of the cast-in-place pile, the device comprises a grouting machine and a slurry storage barrel, one end of a connecting pipe is provided with a grouting mechanism used for grouting, differential management of branch pipelines is achieved through the grouting mechanism and an intelligent pressure controller during grouting, and the grouting efficiency is improved. The grouting material can be effectively utilized, so that more slurry is saved, the slurry is diffused more uniformly, the continuity of an impervious layer is better, the slurry is directionally jetted due to compression expansion of the elastic microporous sleeve, the construction time of a single pile can be shortened through a directional jetting technology, the comprehensive manufacturing cost is reduced, and the process is divided into three grouting stages, so that the construction efficiency is improved. A main body impervious layer is formed through first-time grouting, shrinkage cracks are filled for the second time, pressure is maintained for the third time to ensure compactness, the shrinkage cracks are better eliminated through the three-time grouting technology, and the permeability coefficient of a pile-soil interface is reduced.

The application relates to the technical field of solar cells, in particular to a cell piece and a photovoltaic module. The cell piece comprises a welding structure, a busbar fishhook and a busbar electrode. The welding structure comprises an edge welding structure located at the outermost side, the busbar fishhook is connected with the edge welding structure, and the busbar fishhook comprises a fishhook gap. The busbar electrode comprises a first electrode and a second electrode connected with the busbar fishhook, the first electrode is located between the second electrode and the edge welding structure, the first electrode penetrates through the fishhook gap along a second direction, and the second electrode is disconnected at the fishhook gap. The side of the first electrode located at the outermost side and away from the edge welding structure is an edge area of the cell piece, the arrangement spacing of at least part of the auxiliary busbar electrodes in the edge area is smaller than that of the auxiliary busbar electrodes in the remaining area, the number of the auxiliary busbar electrodes arranged in the edge area can be increased, the current collection efficiency can be improved, the electronic transmission path can be optimized, the brightness uniformity of EL test and the output power can be improved.
