Construction method for strengthening base layer soil body under floor cushion layer
The invention discloses a construction method for strengthening a base layer soil body under a floor cushion layer, belongs to the technical field of building construction, and aims to solve the problem that the floor construction quality is affected since no floor pile is available on a floor of an industrial workshop or warehouse and the base layer soil body under the floor cushion layer partially settles and sinks. The construction method comprises the following steps: firstly selecting a plurality of grouting points on the floor cushion layer and marking; then forming grouting holes at the grouting points and laying grouting pipes; next preparing slurry for later use; next injecting slurry into the grouting holes through the grouting pipes; finally removing the grouting pipes and plugging the grouting holes. According to the construction method, points are arranged in blocks on the floor cushion layer for grouting to form grouting buttresses to support each floor unit, so the carrying capacity and the compactness of the base layer soil body under the floor are improved, and a gap between the floor cushion layer and the base layer soil body is effectively filled; thus settlement produced by factors such as insufficient bearing capacity or non-compactness of the base layer soil body under the floor is effectively prevented, and the construction quality of the floor is guaranteed.
