对于已形成的海蚀孔洞通常采用柱支撑、嵌补、回填、灌浆等措施进行加固。海

For sea holes formed usually by column support, fill inlay, backfilling, grouting reinforcement measures. <br>When sea cave large thickness and can rock fracture development, supported at its reinforced concrete disposed at a weak, for span, more fractures by column region, a combination of the expansion of the supporting plate surface. <br>Cave can be shorter near stone, masonry fill inlay support.

The formed sea erosion hole is usually reinforced by measures such as column support, inlay, backfilling, and grouting.<br>When the sea cavity body is large, it can set the reinforced concrete support in its weak point according to the thickness of the rock body and the degree of development of the crack, and expand the support surface by combining columns and plates in areas with large span and more cracks. The shorter hole body can be used to take the near-to-stone, pulp inlay to complement the support.

For the formed sea erosion holes, column support, inlay, backfill, grouting and other measures are usually used for reinforcement.<br>When the cavern is large, the reinforced concrete support can be set at the weak part according to the thickness of the rock mass and the degree of crack development. For the area with large span and more cracks, the support surface can be expanded by the combination of columns and plates.<br>For the shorter tunnel body, stone can be taken from the nearest place and grouted for inlaying and supporting.<br>
