第一章編制說明及依據(jù)

1.1編制說明

1.1.1編制目的

任城路-王母閣路升級(jí)改造綜合管廊工程地處濟(jì)寧市老城區(qū)城市主干路，周

邊建筑物多，地下管線密集，地質(zhì)條件較為復(fù)雜，是全國少有位于中心城區(qū)舊路

改造綜合管廊工程，具有技術(shù)難度高，施工風(fēng)險(xiǎn)大的特點(diǎn)。為保證管廊深基坑開

挖順利進(jìn)行，同時(shí)確保基坑施工過程中周邊建筑物、道路和市政管線不受破壞，

通過認(rèn)真研究設(shè)計(jì)文件并借鑒現(xiàn)有成熟施工經(jīng)驗(yàn)、技術(shù)，綜合考慮綜合管廊周邊

環(huán)境的特點(diǎn)、地質(zhì)條件、機(jī)具設(shè)備配套能力、交通疏導(dǎo)等方面因素編制了本方案

指導(dǎo)施工。本方案編制范圍為任城路-王母閣路升級(jí)改造綜合管廊工程基坑工程，

包括基坑圍護(hù)、止水帷幕、降水、土方開挖等內(nèi)容。

1.1.2編制原則

1、貫徹執(zhí)行國家、行業(yè)和地方的方針、政策及工程建設(shè)標(biāo)準(zhǔn)、制度。

2、確保方案安全可行、針對(duì)性與操作性強(qiáng)、能縮短工期，施工方案經(jīng)濟(jì)合

理、堅(jiān)持技術(shù)先進(jìn)性、科學(xué)合理性。

3、根據(jù)工程地質(zhì)、水文地質(zhì)、場(chǎng)地條件、地下管線、周邊環(huán)境及工期要求

等選擇具有實(shí)用性、最佳的施工方案和機(jī)具設(shè)備。

4、以確保工期并適當(dāng)提前為原則，安排施工進(jìn)度計(jì)劃。

5、以確保質(zhì)量目標(biāo)，選擇專業(yè)化的施工隊(duì)伍，不斷提高施工技術(shù)水平和施

工機(jī)械化、工廠化、標(biāo)準(zhǔn)化、信息化、智慧化水平。
