Grouting leaking stoppage construction method
The invention relates to a grouting leaking stoppage construction method. The grouting leaking stoppage construction method comprises the following steps that S1, a test area is selected; S2, a test grouting hole is drilled in a crack of the test area, water is injected into a water stop needle head through a high-pressure grouting machine, the water outlet time of a water outlet point is recordedas T1; S3, air is introduced into the water stop needle head; S4, grouting liquid is poured into the water stop needle head, the time for the grouting liquid to reach the water outlet point is recorded as T2, the ratio of T2 to T1 is calculated as N; S5, a grouting hole is drilled in the crack, water is injected into the water stop needle head through the high-pressure grouting machine, the wateroutlet time of the last water outlet point is recorded as T3; S6, other water outlet points are blocked through a mortar waterproof agent; S7, grouting liquid is poured into the water stop needle head, the pouring time is T3 * N; and S8, the water stop needle head is detached, and the detaching position is coated with a leaking stoppage material. The grouting leaking stoppage construction methodhas the effects of improving the wall leaking stoppage effect and prolonging the water stop time.
本申请涉及一种注浆堵漏施工方法，包括如下步骤：步骤S1，选取试验区；步骤S2，在试验区的裂缝处钻制试验注浆孔，通过高压灌浆机向止水针头内注水，并记录出水点的出水时间为T1；步骤S3，向止水针头内通气；步骤S4，向止水针头内灌注注浆液，记录浆液到达出水点的时间为T2，计算T2与T1的比值为N；步骤S5，在裂缝处钻制注浆孔，通过高压灌浆机向止水针头内注水，记录最后一个出水点出水的时间为T3；步骤S6，将其他出水点通过砂浆防水剂封堵；步骤S7，向止水针头内灌注注浆液，且灌注时间为T3*N；步骤S8，将止水针头拆下，在拆除位置涂抹堵漏材料，本申请具有改善墙体堵漏效果、延长止水时间的效果。
