Pludge closed water construction method influenced by seawater tides
The invention relates to a closed water construction method for a ponding pit influenced by seawater tides. The method comprises the following steps: assembling and welding a steel plate caisson, welding a lifting ring, preparing in the ponding pit in advance, and lifting the steel plate caisson into the ponding pit. The steel plate caisson is formed by assembling and welding steel plates with the thickness of 10 mm, the caisson is divided into a bottomed caisson method and a bottomless caisson method, the bottomed caisson method is adopted for the ponding pit foundation without the pile foundation, and the bottomless caisson method is adopted for the ponding pit foundation with the pile foundation. The vertical external corner and the bottom external corner of the steel plate caisson are both made of 75 * 75 * 6 mm angle steel, the rigidity of the caisson is enhanced, a water stop steel plate with the width of 150 mm and the thickness of 3 mm is welded to the middle of the caisson, in order to hoist the caisson conveniently, 20 round steel hanging rings with the length of 650 mm are welded to the positions, 500 mm away from the edges, of the tops of the four corners of the caisson, and the welding length is 400 mm. The steel plate caisson construction can improve the working efficiency, save the site, shorten the construction period and reduce the cost.
本发明涉及一种受海水潮汐影响的积水坑闭水施工方法，组装焊接钢板沉箱，焊接吊环，积水坑内预先准备，将钢板沉箱吊入积水坑内。钢板沉箱采用10mm厚钢板组装焊接而成，沉箱分为有底沉箱、无底沉箱2种做法，积水坑基础无桩基的采用有底沉箱做法，积水坑基础有桩基的采用无底沉箱做法。钢板沉箱竖向阳角、底面阳角均采用75×75×6mm角钢，加强沉箱的刚度，在沉箱中间部位焊接150mm宽，3mm厚止水钢板，为方便吊运沉箱，在沉箱四个角顶部距边500mm处部位焊接650mm长圆钢20吊环，焊接长度为400mm。采用钢板沉箱施工能够提高工作效率、节约场地、缩短工期、降低成本。
