Construction joint water stop construction method

LIU YUANYUAN

A construction joint water stop construction method comprises the following steps that steel bar construction of a bottom plate is completed, steel bars comprise vertical steel bars perpendicular to the bottom plate, the vertical steel bars are partially embedded in the bottom plate, and the other parts of the vertical steel bars are higher than the bottom plate; batten back ridges are bound on the vertical steel bars; formwork erecting operation is conducted on the bottom plate to form a pouring space, the batten back ridges and the vertical steel bars are located in the pouring space, and the batten back ridges are located on the edge of the pouring space; concrete pouring is conducted in the pouring space, a water stop plate is pre-buried during pouring, and the height of the water stop plate is larger than that of the batten back arris; and the batten back edges are dismantled, so that the table-shaped water stop seam is formed. According to the construction joint water stop construction method, preliminary water prevention is conducted through the water stop plate, after water flow permeates and overflows the water stop plate, the water flow flows to the table-shaped water stop joint, the table-shaped water stop joint can increase the water flow leakage difficulty, and therefore the effect of reducing wall corrosion is achieved.

一种施工缝止水施工方法，包括如下步骤：完成底板的钢筋施工，其中，所述钢筋包括垂直于所述底板的竖直钢筋，所述竖直钢筋部分预埋在底板内，所述竖直钢筋另一部分高出于所述底板；在所述竖直钢筋上绑扎木方背楞；在底板处进行支模作业以形成浇筑空间，其中，所述木方背楞及所述竖直钢筋位于浇筑空间内，且所述木方背楞处于所述浇筑空间边缘；向所述浇筑空间内进行混凝土浇筑，并在浇筑时预埋止水板，且所述止水板的高度高于所述木方背楞；拆除所述木方背楞，以形成台型止水缝。该施工缝止水施工方法，通过止水板进行初步防水，当水流渗溢过止水板后，流动至台型止水缝，台型止水缝能够增加水流渗漏难度，从而减小墙体腐蚀的效果。
