通滸路雨污水管施工方案

一、 設(shè)計(jì)概況
本工程為蘇州新區(qū)通滸路一期工程，全長(zhǎng)2705.4米。
本工程排水體制為雨污水分流制。
根據(jù)蘇州新區(qū)北片污水方案，通滸路一期：建林路以西的污水管由西向東鋪設(shè)，管徑d800、d1000、途中以過(guò)河管、倒虹管形式過(guò)河，建林路以東的污水管由東往系西鋪設(shè)，管徑d600：兩路污水管匯合后往南鋪設(shè)d1200管，沉管過(guò)滸光河，進(jìn)建林路污水管泵站，本工程到河北岸為止。污水管位于道路北側(cè)公交車道下，管中心距道路中心線16.5米、20米，沿途預(yù)留DN400、d 600、d800的污水支管。
W3-W4，W12-W15的污水干管及d600、d800污水支管、d1200污水橫穿管位于亞粘土夾亞砂土層，管道埋設(shè)較深，須采用井點(diǎn)降水。
為確保位于砂土地基的污水管道質(zhì)量對(duì)W30-W32、W33-W45 d1000污水干管及d1200污水干管進(jìn)行壓密注漿。
雨水管按照就近入河的原則，分別排入路南側(cè)滸光河及9+581處的小河內(nèi)。雨水管二根，分別位于道路南北兩側(cè)公交車道下，管中心距人行道側(cè)石1.5米，雨水管管徑為DN400、d600、d800 、 d1000 d1200，沿途預(yù)留DN400、d 600、d1000雨水支管。
二、 污水管工程施工技術(shù)方案
1、測(cè)量放樣
根據(jù)圖紙和給定控制點(diǎn)，在現(xiàn)場(chǎng)測(cè)
Tong Yu Hu Road sewer construction program

A design overview
This works through Hu Road, Suzhou New District, a project length of 2705.4 meters.
This works for the rain water drainage system streaming.
Suzhou New District North tablets sewage under the program, through Hu Road, 1: Forest Road to the west of the construction of sewers laid from west to east, diameter d800, d1000, on the way to river management, the form of inverted siphon crossing the river, built east of Forest Road sewage pipes laid from east to west line, diameter of d600: Two after convergence south sewer pipe laying d1200, Shen Hu-ray tube over the river into the construction of Forest Road sewer pump station, the project to the north of the river so far. Sewer in the road north of bus lanes, the control center of the center line of 16.5 meters from the road, 20 meters, along the reserved DN400, d 600, d800 sewage branch.
W3-W4, W12-W15 trunk sewers and d600, d800 sewage branch, d1200 sewage pipe located across the sub-folder of Sandy clay layer, pipe laying and deeper, to adopt the well point dewatering.
To ensure that the sewage pipes in the sand foundation of quality on the W30-W32, W33-W45 d1000 d1200 trunk sewers and trunk sewers for compaction grouting.
Rainwater into the river in accordance with the principles of proximity, respectively, into the light River Road, south of Hu and 9 +581 stream within the Department. Rain water pipe 2, respectively, north and south sides of bus lanes in the road, the control center 1.5 m from the sidewalk side of the stone, rainwater pipe diameter DN400, d600, d800, d1000 d1200, along reserved DN400, d 600, d1000 rain branch.
Second, sewer construction technology programs
1, Survey setting
According to the drawings and given control points, measured in the field
