Mouth, aluminum alloy holding cuffs, upper manhole, the column being connected with side wall；
The open caisson two sides have been provided with the biggish mouth that punches of height difference great disparity, and respectively cable laying disengaging open caisson is passed through
Comb punch mouth and push pipe punches mouth, upper manhole is that the hole to punch at the top of open caisson is arranged in, the cantilever support and Gao Li
Column is connected with, and the cable anchor ear and fixed two connecting assemblies of T-type fishplate bar are connected with cantilever support, institute
It states fixed bracket to be connected with low column, aluminum alloy holding cuffs, the high column and bottom is provided on the fixed bracket
Plate is connected by built-in fitting, and built-in fitting is made of column fixed plate and expansion bolt, and the low column and bottom plate pass through built-in fitting
Connection, the connected column of the side wall and pre-embedded steel slab are welded to connect, and pre-embedded steel slab is the steel plate for being embedded in side wall.
Further, the high column root joints cement mortar protective cap.
Further, the low column root joints cement mortar protective cap.
Compared with prior art, the utility model has the beneficial effects that the cable bearer of the open caisson uses a kind of overhanging type
Bracket, this overhanging type bracket can make cable raising compared with big corner, substantially reduce the length of open caisson, reach reduction construction and make
The purpose of valence, and open caisson also more adapts to the demand of larger depth than conventional cable work well.
