Grouting method and press-in type hollow grouting anchor pipe
The invention discloses a grouting method and a press-in type hollow grouting anchor pipe. The press-in type hollow grouting anchor pipe comprises a hollow anchor rod, wherein grouting holes are formed in the peripheral side of a rod body of the hollow anchor rod, one end of the hollow anchor rod is in a pointed tail shape, the other end of the hollow anchor rod is detachably connected with an anchor head, and one end of the anchor head is inserted into the hollow anchor rod. The invention further discloses the grouting method, which is applied to the press-in type hollow grouting anchor pipeand is characterized in that the hollow anchor rod provided with the anchor head is mechanically pressed into a rock-soil foundation to be constructed, then the anchor head is taken down, grout is injected into the hollow anchor rod from the position, provided with the anchor head, of the hollow anchor rod, and the grout is enabled to flow out of the grouting holes and fill the periphery of a rodbody and a rock-soil foundation hole drilled by the hollow anchor rod. In conclusion, by the adoption of the press-in type hollow grouting anchor pipe, two steps of hole forming and anchor pipe press-in can be combined into a whole, the construction process is simplified, the construction period is shortened, the press-in type hollow grouting anchor pipe is particularly suitable for construction of loose and soft layers such as blast furnace slag, soil layers and sand layers, in addition, the anchor head can be repeatedly used, and the construction cost is reduced.
本发明公开了一种注浆方法及压入式中空注浆锚管，该压入式中空注浆锚管包括杆身周侧设有注浆孔的空心锚杆，空心锚杆的一端呈尖尾状，空心锚杆的另一端可拆卸地连接有锚头；锚头的一端插入空心锚杆内。本发明还公开了一种注浆方法，应用于上述压入式中空注浆锚管。将装有锚头的空心锚杆机械压入待施工的岩土地基内，再取下锚头，从装设锚头的空心锚杆处向空心锚杆内注入浆液，浆液从注浆孔内流出并填充再杆身外周与空心锚杆所钻出的岩土地基孔内，综上，采用上述压入式中空注浆锚管可将成孔、锚管压入这两个步骤的合二为一，简化了施工工艺，节约工期，尤其适用于高炉碴体、土层、砂层等松散软弱层的施工；此外，锚头可重复使用，降低了施工成本。
