湖北水利水电公司整理的堤防工程主要注意的施工方法

一、堤(di)防工程(cheng)主要注意(yi)的施(shi)工方法

1、设计压实度(du)要根据《堤防工程设计规范》来(lai)确定。

2、施(shi)工(gong)含水量按土料试验所确定(ding)的值(zhi)控(kong)制。

3、土料的施工压实(shi)(shi)度、干(gan)密度是根据土场多(duo)组代表性(xing)的土样(yang)进(jin)行击实(shi)(shi)试(shi)验所得(de)。

二、堤(di)(di)(di)(di)(di)(di)防(fang)(fang)(fang)工(gong)(gong)程:沿河、渠、湖(hu)、海岸(an)或(huo)行(xing)洪(hong)(hong)区(qu)、分(fen)(fen)洪(hong)(hong)区(qu)、围(wei)垦(ken)区(qu)的(de)(de)边缘修筑的(de)(de)挡(dang)水建(jian)筑物称为堤(di)(di)(di)(di)(di)(di)防(fang)(fang)(fang)。堤(di)(di)(di)(di)(di)(di)防(fang)(fang)(fang)是世界上较早广(guang)为采用的(de)(de)一种重要(yao)防(fang)(fang)(fang)洪(hong)(hong)工(gong)(gong)程。筑堤(di)(di)(di)(di)(di)(di)是防(fang)(fang)(fang)御(yu)洪(hong)(hong)水泛滥,保护居民和(he)工(gong)(gong)农业生产的(de)(de)主要(yao)措施。河堤(di)(di)(di)(di)(di)(di)约束洪(hong)(hong)水后,将洪(hong)(hong)水限制在行(xing)洪(hong)(hong)道(dao)内,使同等(deng)流量的(de)(de)水深增加(jia),行(xing)洪(hong)(hong)流速增大,有利于泄洪(hong)(hong)排沙(sha)。堤(di)(di)(di)(di)(di)(di)防(fang)(fang)(fang)还可(ke)以抵挡(dang)风浪及(ji)抗(kang)御(yu)海潮。堤(di)(di)(di)(di)(di)(di)防(fang)(fang)(fang)按(an)(an)其修筑的(de)(de)位置不(bu)同,可(ke)分(fen)(fen)为河堤(di)(di)(di)(di)(di)(di)、江(jiang)堤(di)(di)(di)(di)(di)(di)、湖(hu)堤(di)(di)(di)(di)(di)(di)、海堤(di)(di)(di)(di)(di)(di)以及(ji)水库、蓄滞洪(hong)(hong)区(qu)低洼地区(qu)的(de)(de)围(wei)堤(di)(di)(di)(di)(di)(di)等(deng);按(an)(an)其功能可(ke)分(fen)(fen)为干堤(di)(di)(di)(di)(di)(di)、支堤(di)(di)(di)(di)(di)(di)、子堤(di)(di)(di)(di)(di)(di)、遥堤(di)(di)(di)(di)(di)(di)、隔堤(di)(di)(di)(di)(di)(di)、行(xing)洪(hong)(hong)堤(di)(di)(di)(di)(di)(di)、防(fang)(fang)(fang)洪(hong)(hong)堤(di)(di)(di)(di)(di)(di)、围(wei)堤(di)(di)(di)(di)(di)(di)(圩(wei)垸)、防(fang)(fang)(fang)浪堤(di)(di)(di)(di)(di)(di)等(deng);按(an)(an)建(jian)筑材料可(ke)分(fen)(fen)为:土堤(di)(di)(di)(di)(di)(di)、石堤(di)(di)(di)(di)(di)(di)、土石混合堤(di)(di)(di)(di)(di)(di)和(he)混凝土防(fang)(fang)(fang)洪(hong)(hong)墙等(deng)。
