前言苏南南匯县滨海部分,以地形突出,復受潮汐涨落冲积的影响,岸线逐渐东移。前人围筑堤塘,拒潮墾殖,因之该县塘线纵横错雜,每逢夏季暴雨,土塘内之积水无法宣洩,易致泛滥。因此乃计议兴筑磗拱涵洞十二座于预备塘上,籍作该塘内水道排洪之用。沿塘群众仍恐排水不足,又建议县府,筹资增建四座,现共十六座(1.倪家路港涵;2.潘家泓涵;3.界河涵;4.长溝涵;5.水晶宫涵;6.老港涵;7.六灶港涵;8.小窪港涵;9.外三灶涵;10.石皮(氵勒)涵;11中橫港涵;12妙港涵;13二灶泓涵;14七十步头涵;15石乱子港涵;16.四汢港涵)。全部工科费为大米五五二、二一二·○三市斤,其中加固工程工料费,为大米九九、二八○·六八市斤。涵式採用一公尺徑拱式磗涵,长为一三·五公尺,出水口闸门,用圆形动啓闭铁门,以防海水倒灌,进水口闸门用洋松闸板,以资调节港河水位。
Foreword Nanning County coastal part of the prominent terrain, complex tidal fluctuations alluvial impact, the shoreline gradually eastward. The predecessors built dykes, refuse tide reclamation, because of the county Tong line criss-cross, during the summer heavy rains, ponds within the water can not vent, easy to cause flooding. Therefore, it is deliberately proposed to build 磗 arch culvert twelve in the preparatory pond, native to the pond for flood discharge purposes. People along the pond are still afraid of lack of drainage, but also recommended that the county, raising funds to build four, now a total of sixteen (1. Ni Road Lu Han; 2. Panjia Hong Han; 3. Boundary River culvert; 4. Long trench culverts; Culvert; 6. Old Hong Kong culverts; 7. Liuzao harbor culverts; 8. Xiaowa Harbor culverts; 9. Three outer culvert culverts; 10. Stone bark (Lang) Han; Two stoves Hong Han; 14 seventy step head culvert; 15 stone chaos Hong Kong and Han; 16 Sifang harbor culvert). All engineering fees for rice five five two, two one two three three jin, including reinforcement works fee for rice, ninety-nine, two hundred and eighteen sixty-six pounds. Han-style culvert with one meter diameter arch Han, a length of 13.5 meters, the outlet gate, with a circular opening and closing of the iron gate to prevent seawater intrusion, inlet gate with a foreign pine gate to the capital Adjust the port water level.
