挡水围堰和抛石挤淤施工方案和平而布置

挡水围堰和抛石挤淤施工方案和平面布置

 

一、工程概况

本标段在K6+280~K6+500,K6+760~K6+990段的道路路基分别落入老大港河床内,其宽窄不一,以及K7+020处老大港河横贯整个路幅,且在K7+020处有一个横向排水管涵和路基左幅36m处沿道路方向布置有排水箱涵,箱涵断面×m2和×m2。

根据设计图纸和技术交底内容等相关文件,该叁段、处河道内路基全部采取抛石挤淤方案进行施工,抛石工程总量约为40000m3,其中K6+280~K6+510段约为15000m3,K6+760~K6+990段约为15000m3,K7+020处约为10000m3。

二、施工部署及方法

由于该叁段、处不连续,且抛石工作量很大,拟采用逐段施工的方案进行抛石挤淤,即分段截流、抽排河水、抛石挤淤。

1、首先对K7+020处横贯路幅的老大港河进行软基路堤处理。

第一步,两端截流,南端利用已修建好的施工便道,做为挡水围堰,北端在路幅坡脚线处再做一道挡水围堰,具体位置及断面尺寸见平面布置图;第二步,抽排截流段内的河水,河水往北端抽排;第三步,抛石挤淤,和33.6m时,上压路机对其进行充分碾压,要求达到压路机在上面行走不塌陷即可,然后进行管涵施工,待管涵施工完毕,再按照设计图纸抛填至设计标高。

2、再对K6+760~K6+990段进行软基路堤处理,第一步,做挡水围堰,先做K6+990处挡水围堰,待围堰做至能使机械设备跨越河道,而河流又未合拢,河水能自由下泻时止,在路幅坡脚线外开挖排水明渠,将K6+760处老大港河水改道走临时排水明渠,排水明渠的断面尺寸见附图,明渠的纵向坡度按0.5%考虑,以保证排流顺畅。

再进行K6+990处围堰合拢和K6+760处挡水围堰,其布置见平面图;第二步,抽排截流段内的河水;第三步,抛石挤淤,由于路幅左侧36m处有排水箱涵,且箱涵的底口标高分别为33.2m和33.8m,而河床高程分别为33.5m和34.1m,箱涵底口标高低于河床高程约0.3m,决定抛石范围至箱涵边为止。

根据软基路堤处理设计图路施-10,抛石面高程控制在35.5m,用压路机碾压,做到压路机碾压时不塌陷,将挤出的淤泥用挖机堆放在绿化带沿线。

3、后对K6+280~K6+510段进行老大港河的河床内软基路堤处理。

第一步,开挖排水明渠。

虽K6+280处污水从道路右幅横贯路幅至道路左恻,但流量不是很大,开挖排水明渠的断面尺寸可适当根据现场情况决定,以不影响污水排流为宜;第二步,截流。

截流位置见平面图。

第三步,抛石。

抛石顺序为道路右侧向左侧推进,挤出淤泥可用挖机堆放在绿化带位置,施工程序与K6+760~K6+990段相同。

4、抛石时用挖机将大块石料高举下抛,再用挖机斗将石料往下挤压,直至挤压到持力层时止。

三、施工进度

抛石挤淤工作计划从11月15日开始,12月5日完成。

3、材料计划

材料来源:

抛石材料均从场外购买(料进足后再进行抛填)。

五、质量及安全保证措施

1、质量保证措施

为了保证抛石挤淤的施工质量,①首先必须保证抛石材料合符要求,不能将含有垃圾、树根、淤泥等杂物混入其中。

②其次,抛石挤淤的程序要符合设计或规范的规定,设计文件中已有要求:

a、由路基中央向两侧进行,呈“凸”字形前进。

b、先选用较大的石块,用挖机举高再让石块自由下落。

c、用重型压路机碾压,使石块嵌锁挤紧,排挤淤泥。

③最后将挤出的淤泥用挖机清除干净。

2、安全保证措施:

①在整个施工过程中,我部将派出专职安全员阳丽军,对现场的安全全权负责;

②在施工现场要设置醒目的标志,提醒作业人员或外来人员注意安全,防止机械设备或运输车辆伤人。

挖机抛石时,还需设置围栏或增派安全员。

③由于石头的运输是在夜间进行,所以现场的照明工作和车辆的指挥均需有专人负责。

④抽水用电和照明用电需有专职电工负责,施工期间电工要对电线、开关、配电箱等电路、电器元件随时检查,发现隐患及时改正,防止安全事故的发生。
