The invention discloses a local terrace concrete settling treatment method. The local terrace concrete settling treatment method comprises the following steps that firstly, a plurality of cylindricalgrouting pipes are prepared, and an upper flange plate and a lower flange plate are fixedly arranged at the upper end and the lower end of each grouting pipe and the left side and the right side of each grouting pipe correspondingly; secondly, the grouting pipes are arranged in a terrace settling crack at intervals, and the lower flange plates on one sides of the grouting pipes abut against the position below a settled concrete terrace layer; thirdly, after the grouting pipes are rotated, the grouting pipes are used for elevating the settled concrete terrace layer; fourthly, grouting is conducted on grouting ports of the grouting pipes, and grout is pressed into a soil layer; and fifthly, after the grout reaches the strength, all the grouting pipes are taken out after the grouting pipes are rotated, and meanwhile the grout is continuously injected into gaps. The obtained local terrace concrete settling treatment method is simple and fast in treatment manner, and the settling position can be grouted after the settled concrete terrace is elevated.
本发明公开了一种局部地坪混凝土沉降处理方法，包括如下步骤：S1，准备多根呈筒状的注浆管，并在每根注浆管上下两端、注浆管的左右两侧分别固定安装有一块上翼缘板和下翼缘板；S2，将注浆管间隔置于地坪沉降的裂缝中，使注浆管其中一侧的下翼缘板抵在沉降后的混凝土地坪层下；S3，旋转注浆管后通过注浆管抬升沉降的混凝土地坪层；S4，向各个注浆管的注浆口注浆，使浆液被压入土层中；S5，待浆液达到强度后，旋转注浆管后取出所有注浆管，同时，向缝隙内继续注入浆液。本发明得到的局部地坪混凝土沉降处理方法处理方式简单、快捷，能够将沉降混凝土地坪抬升后并对沉降位置进行注浆。
