The chute that connects Dun Bi is all arranged on the Dun Bi of described A abutment pier, middle pier, two slide blocks of described top slice stretch into respectively the chute of A abutment pier, middle pier, be connected with the pulley on being closely against A abutment pier, Zhong Dun service depot inside wall slide rail, when folding weir body lifting, the band movable slider moves in chute, and two pulleys are at the folding weir body lifting top slice of straining all the time in service.
The job practices on a kind of modular folding weir, carry out according to the following steps successively:
(1) setting-out is measured in the location, weir, removes place, location, weir riverbed and two foreign material on the bank, excavation and the processing of weir base, weir shoulder;
(2) build under pump house and weir base plate after the access path in the riverbed, roll the weir base;
(3) build A abutment pier, Zhong Dun, B abutment pier after, build weir base plate and scouring sluice;
(4) build upstream aileron, downstream aileron, guide wall after, build bedding, training for sediment bank, protection-apron;
(5) top slice after assembly unit on the base plate of weir, is arranged on top slice on the hinge of upper hinge pier; Lower weir plate is arranged on lower weir plate on the hinge of lower hinge pier after assembly unit on the base plate of weir;
(6) adopt scaffold and crane the weir crest plate to be installed on the hinge on top slice and lower weir plate top;
