湖北省随县车水沟灌区的经验车水沟灌区的干渠上架有木渡槽六座,防漏的主要办法是:(1)选用适当的木材:槽板选用当地出产的松木制造,以降低造价,板、横梁等重要构件则选用桑槐等坚实木料,延长使用时间,以免时常更换。(2)渡槽安装前,先在槽板、梁板、夹板等单件上,涂热桐油两遍,架好后再涂油一遍,并用臭油嵌缝。这比装好后再涂油的防漏防腐效果高。(3)槽板先用枣角钉(两端尖形状象枣核)拼接成大块,然后再成块地钉在横梁或侧夹板上。侧槽板和底扳拼接时,仿照造木船的办法,用压较将侧板压紧,每公尺宽压窄四公分,然后用钉钉牢,这样比用单板直接钉在横梁上,接缝严密,并防板子错动变
The experience of Suishuogou Irrigation District in Suixi County, Hubei Province There are six main wooden aqueducts in the main canal of Chengtu Irrigation District. The main ways to prevent leakage are as follows: (1) Appropriate wood is selected: Grooved boards are made of locally-produced pine wood to reduce the cost , Boards, beams and other important components are selected solid wood sampan timber, extended use of time, so as to avoid frequent replacement. (2) Before installing the aqueduct, apply tung oil twice on the trough, beam, plywood and other single pieces, and apply the oil again after it has been erected. This is better than the leakproof and anti-corrosion effect after being coated. (3) slot board with the first date angle nail (both ends of the tip shape like jujube) spliced into large pieces, and then block into the beam or side of the splint. Side slot board and the bottom pull the splicing, follow the method of making wooden boats, the pressure will be compared with the side panels, each meter wide and narrow pressure of four centimeters, and then nail nailed, so than the veneer directly nailed to the beam, Seams tight, and anti-Board wrong move
