Highway subgrade maintenance pavement crack pouring method
The invention discloses a highway subgrade maintenance pavement crack pouring method which comprises the following steps that S1, manual cutting is conducted at the starting end of a pavement crack inadvance, a rectangular cutting groove with the set width is obtained, and the width of the rectangular cutting groove is 1.25-2 times of the average value of the actual width of the crack; S2, a maincutter of a grooving mechanism is placed in a groove which is cut in advance, and at the moment, the vertical distance between the highest point of the cutting track of an auxiliary cutter in the groove and a groove opening of the rectangular groove is not smaller than half of the depth of the rectangular groove; S3, when the vertical sliding rotating shaft drives the driving gear to move downwards, the driving gear ejects a pair of driven gears which are symmetrically arranged on the left side and the right side of the driving gear and have the reset function; S4, after cutting is completed,the cutting groove is purged and cleaned, and slag cuttings are removed; and S5, crack pouring glue is injected into the cutting grooves through a sprinkling irrigation device. When crack pouring isconducted according to the construction method, the repairing effect on pavement cracks is extremely good, and durability is longer.
本发明公开了一种公路路基养护路面灌缝方法，包括以下步骤：S1、在路面裂缝的起始端处预先进行人工切割，得到一个既定宽度的矩形切槽，矩形切槽宽度为裂缝实际宽度平均值的1.25‑2倍；S2、将切槽机构的主切刀安置于前面预先切好的切槽之内，此时切槽内副切刀切削轨迹的最高点距离矩形切槽槽口的竖直间距不小于该矩形切槽深度的一半；S3、竖直滑转轴带动主动齿轮下移时，主动齿轮将其左右两侧对称布置的一对具有复位功能的两从动齿轮顶开；S4、待切割完毕后对切槽进行吹扫清理，除去渣滓切屑；S5、利用喷灌装置朝切槽内注入灌缝胶。按本发明的施工方法进行灌缝，对路面裂缝修护效果极好，耐久性更长。
