The invention discloses a segmented construction method for a gravity retaining wall, and belongs to the technical field of building construction. According to the segmented construction method for the gravity retaining wall, a plurality of evenly-distributed anti-seepage balls can be pre-buried in a construction joint, and after a wall body is integrally formed, the caulking action of the anti-seepage balls is triggered through a magnetic field, the anti-seepage balls extend towards pores existing at the construction joint under the traction of magnetically-induced microspheres, after water permeates into the anti-seepage balls, the water is conveyed into the anti-seepage balls through a fiber pipe, a chemical reaction is triggered in a triggering ball to generate a large amount of gas, and magnetic plugging particles are migrated to the pores along with the gas under the guiding action of magnetic force. On one hand, continuously permeating water is blown out, on the other hand, the magnetic plugging particles can obviously expand for plugging after absorbing the water, the air pressure is increased along with continuous generation of gas until an isolation spherical shell is burst, under the extrusion effect, a curing material is forced to migrate to the gap to trigger the curing action, so that high-strength permanent plugging is realized, effective anti-seepage can be achieved, and therefore, the construction quality of the retaining wall is indirectly improved.
本发明公开了一种重力式挡土墙分段式施工方法，属于建筑施工技术领域，本发明可以通过在施工缝处预埋上多个均匀分布的防渗球，在墙身整体成型后通过磁场触发防渗球的嵌缝动作，通过磁引微球的牵引向施工缝处存在的孔隙进行延伸，当水分渗透至内部后，由纤维管将水分输送至防渗球内部，并在触发球内触发化学反应产生大量的气体，在磁力引导作用下磁性封堵颗粒随气体一起迁移至孔隙处，一方面吹出继续渗透的水分，另一方面磁性封堵颗粒在吸收水分后会显著膨胀进行堵塞，随着气体的持续产生气压增大直至撑破隔离球壳，并在挤压作用下迫使固化材料也迁移至空隙处触发固化动作，实现高强度的永久封堵，可以有效防渗，从而间接提高挡土墙的施工质量。
