Construction device and method for reinforcing loose soil body
The invention relates to a construction device and method for reinforcing a loose soil body, a grouting steel pipe is used as a pile formwork for reinforcing the loose soil body, after the grouting steel pipe is inserted into the soil body, grouting is conducted in the grouting steel pipe, grout extends towards the soil body around the grouting steel pipe through a grouting hole, and after the grout is solidified, the grouting steel pipe and the surrounding soil body form a reinforcing pile; therefore, the fastening degree of the loose soil body is increased; vertical and inclined reinforcing piles are inserted in the position of a loose soil body of the side slope, so that the loose soil body is extruded in the horizontal direction and the inclined direction, and the reinforcing effect of the loose soil body is improved; the method is not only suitable for reinforcing loose soil bodies, but also can be used for reinforcing muddy soil bodies. By means of the construction mode that the inner sleeve is additionally arranged in the grouting steel pipe, it is avoided that when the grouting steel pipe is inserted into a soil body, surrounding loose soil enters the grouting steel pipe through the grouting holes, the grouting effect is influenced, and when the length of the grouting steel pipe meets the length requirement of a reinforcing pile, the inner sleeve is taken out, and slurry is not influenced to be diffused to the periphery through the grouting holes.
本发明涉及一种加固松散土体的施工装置和方法，注浆钢管作为加固松散土体的桩模板，注浆钢管插入土体后，向注浆钢管内注浆，浆液通过注浆孔向注浆钢管周围土体延伸，待浆液凝固后，注浆钢管和周围土体形成加固桩，从而增加松散土体的紧固程度；在边坡松散土体位置插设竖向和斜向的加固桩，使松散土体的水平方向和斜向均受到挤压力，从而增加松散土体的加固效果；本发明不仅适用于加固松散土体，还可用于加固淤泥质土体。通过在注浆钢管内增设内套管的施工方式，避免注浆钢管在插入土体时，周围散土通过注浆孔进入注浆钢管中，影响注浆效果，在注浆钢管长度达到加固桩长度要求时，取出内套管，不影响浆液通过注浆孔向四周扩散。
