Jinhua forest area in order to solve the spring and summer wood flow process, the safe mooring of the raft and flooding head flood impact of wooden accidents, according to local conditions to build two kinds of cement chain pile, are as follows: 1. Large cement pile. It is a one-time pouring poured into reinforced concrete chain pile, the safety of each chain pile hanging capacity for a paste large rows of 120 cubic meters of wood. 2 medium-sized cement chain pile. It is a grade two reinforced concrete chain pile, first prefabricated row cylinder, and then pound chain pile body, the safety of each chain pile displacement of six rows, accounting for 50 cubic meters of wood. The construction site of these two types of cement chain pile, requires the selection of a solid loess layer or rock layer.
