Background

The blind drain refers to a drainage and water interception blind drain which is arranged in a roadbed or a foundation, is filled with coarse-grained materials such as broken pieces and gravels and is paved with a reverse filtering layer. During foundation pit excavation, drainage macadam blind ditches are not formed yet, temporary drainage open ditches are generally required to be excavated in the foundation pit for ensuring foundation pit drainage and earth layering excavation, and the open ditches are used for ensuring drainage effect, so that ultra-wide and ultra-deep drainage ditches can be frequently generated. After the foundation pit is excavated, the open drain ditch in the excavation stage can be generally utilized to be transformed into a blind drain, so that secondary excavation of the groove is avoided. The width and depth of the existing open trench are not consistent with those of the drainage blind trench, if the existing open trench is constructed by adopting the conventional drainage blind trench construction process, on one hand, the implementation is very difficult; on the other hand, if the open trench is directly backfilled for use as a blind trench, a large amount of crushed stone is wasted, resulting in an increase in cost.
