Method of regulating the practice of settlement of the road

The construction of the subsidence slips requires that the structures on both sides of the slits be free to settle and tightly prevent water leakage. Therefore, the settlement slits must pass through the entire section (including the foundation). Settlement of the specific construction methods are as follows:

The basic part: the original foundation of the construction of embedded asphalt wood or asphalt sand board left, as a waterproof use. Such as the basic construction without wood, can also be filled with clay tamping, and in the edge of the surface to 1: 3 cement mortar packing, the depth of about 15cm.

Body part: seam outside the hot asphalt impregnated linen tamponade, the depth of about 5cm, the inside to 1: 3 cement mortar packing, the depth of about 15cm, depending on the thickness of the masonry at the settlement suture may be. Sewing can be filled with asphalt hemp tendons and cement mortar; if too thick, the middle part can also be filled with clay.
