4.工程特点、难点及相应对策Òì±nlù4q´bbs.3c3t.com«çN/È'n^j

(1)工程特点Òì±nlù4q´bbs.3c3t.com«çN/È'n^j

Òì±nlù4q´bbs.3c3t.com«çN/È'n^j

①本桥处于苏溪及鱼塘范围内,需要涉及改沟,鱼塘及河流处需围堰、抽水,填筑便道等,施工干扰比较大。Òì±nlù4q´bbs.3c3t.com«çN/È'n^j

Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
②该地区属于亚热带海洋季风气候,温和湿润,雨量充沛,雨量多集中在3~9月, 7~9月为台风暴雨期,全年大于25 mm的降雨 日为12.3天~15.8天,给施工带来了很多影响。Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
(2)工程重点、难点Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
①本桥有桩基60根,位于河流及鱼塘中,地质情况复杂。Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
②墩台身及承台砼体积大。Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
(3)相应对策Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
①根据桥位地质情况,钻孔桩采用冲击循环钻机钻孔,以加快施工进度。Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
②大体积墩台身砼施工浇筑时,采用降低水化热的措施,加强温控,避免出现大体积砼温度裂纹。Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
③0#台、1#墩、6#台施工时,先采用草袋围堰,然后筑岛填土分层压实。Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
三、总体施工部署Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
⒈总体施工进度安排Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
桥梁工程由一个桥梁专业施工队担负施工,施工队就近租住砖厂厂房,为生活、生产区。主要负责苏溪大桥下部结构施工。计划 2006年7月12日开工, 2007年1月27日前完工,施工计划工期为6.5个月。桥梁工期计划见桥梁工期要求。Òì±nlù4q´bbs.3c3t.com«çN/È'n^j

3.临时工程建设Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
A. 便道便桥:根据现场调查,从324国道K67+500处下里小学对面有一村庄道路可以进入苏溪大桥桥址,经过一旧砖厂,穿过鱼塘埂大约150m,即可进入1#墩位置。鱼塘埂需要拓宽处理,计划利用旧砖厂费旧砖垫路,加宽至4.5m,并压实处理,以方便今后车辆机械进出。0#桥台位于1#墩对面的鱼塘埂位置,有一条约20m宽的河沟隔开,钻孔机械可从324过道进入柳厝村,穿过村庄和稻田可到达0#台位置,但考虑到施工人员的方便,在河沟上用木头搭设一简易便桥,方便施工。6#台在5#墩所在位置鱼塘埂对面的鱼塘埂上,相隔一条约30m长的河沟,钻孔机械可以从6#台位置附近的乡村便道进入,为了方便施工,在河沟上搭设一简易便桥。Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
B. 变压器:桥址附近电源充沛, 在桥址中央增加一台315KW的变压器,以满足钻孔桩、输送泵等大功率机械设备的正常使用。Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
C. 用水方案:桥址附近水源丰富,可利用河沟的水进行施工用水,生活用水可以从附近村庄解决。Òì±nlù4q´bbs.3c3t.com«çN/È'n^j
