1、概述经过几年五个水厂的施工,针对水厂结构物施工中经常会出现的几个渗水环节进行简单说明,具体表现为对拉螺栓、施工缝、橡胶止水带,预埋套管等。2、几个关键部位2.1对拉螺栓:对拉螺栓是一般采用两端套丝的圆钢螺栓,又称穿墙螺栓,也有用扁钢两端留长孔用楔形铁插入固定楔紧。由于在福建大部分地区,水厂占地面积小,很少有足够的施工场地,因此机械化施工程度较低,在结构物土建施工时不容易采取钢制模板施工,一般采取木质模板施工,这样必然要使用对拉螺栓来加固模板。对拉螺栓(对拉螺杆),用于墙体模板内、外侧模板之间的拉结,承受混凝土的侧压力和其他荷载,
1, Overview After several years of construction of five water works, water structures for the construction of several water seepage often occur a brief description of the specific performance of the pull bolts, construction joints, rubber water stop, embedded sets Tube and so on. 2, a few key parts 2.1 on the pull bolt: on the pull bolt is generally used at both ends of the wire sets of round bolts, also known as wall bolts, but also useful to keep long holes at both ends of the wedge iron fixed wedge tight. Due to the small area of the waterworks in most parts of Fujian and the lack of sufficient construction sites, the degree of mechanized construction is relatively low. Therefore, it is not easy to adopt steel formwork construction in civil construction of structures, and wood formwork is generally adopted so that It is bound to use the pull bolt to reinforce the template. Bolt pull (for the screw), used in the wall formwork, outside the template between the tie-in, to withstand the lateral pressure of concrete and other loads,
