高州工区今年新建的小跨径石(砖)拱桥,在拼搭拱架方面学习了“土牛拱胎”代替拱架的办法,在施工中工人又作了一些改进,创造出一种结构简单、施工方便既节约木材又能在经常有水的河道上采用的拱胎。介绍如下:(一)方法(1)在两端桥台基础上竖立立柱(直径14～16公分)每隔1.5公尺一条立桂上用直径18公分帽木,帽木与立柱用码钉连接。(2)在帽木上密铺直径10公分圆木(可利用旧桥面木),圆木在桥孔两端各五枝,用0.6×22直钉与帽木钉定,其余都不加钉,从利以后折除。(3)木台搭好后,在桥孔两端按拱圈的设计内半径利用暂不使用的石料或砖以粘土浆砌,厚度为40～30公分的拱形墙,作为拱模。
Gaozhou work area this year, the newly built small-span stone (brick) arch bridge, in the spell to take the arch frame learning “Tuo cattle” instead of arch way, workers in the construction and made some improvements to create a simple structure, Construction is easy to save timber and can be used on the often watery arch. (1) Methods (1) Erecting upright columns (14-16 cm in diameter) on both ends of abutment base with an 18 cm diameter capped wood at every 1.5 meters, and the cap wood and column are connected with a code . (2) in the hat wood paved diameter of 10 cm roundwood (the old bridge can be used wood), round wood in the bridge ends of the five, with 0.6 × 22 straight nail and hat wood nails, the rest without the nail Dismissed from Lee later. (3) After the wooden platform is set up, the inner radius of the arch ring at both ends of the bridge hole shall be arch-shaped with clay or brick whose thickness is 40-30 centimeters using temporarily unused stone or brick.
