    1)溝開挖
      1) ditch excavation
      首先,在清理后的挖掘區域內,任何土方工程都不能被移走或運至指定地點。
      First of all, within the cleared excavation area, no earthwork can be removed or transported to the designated place.
      基坑開挖以機械開挖為主,人工開挖為輔。基坑開挖為單坡式,坡度為1:0.33。挖掘機挖至距設計標高20cm處時,需人工清理溝底,溝底兩側需留有排水溝,防止溝底浸泡。
      The foundation pit excavation is mainly mechanical excavation, supplemented by manual excavation. The excavation of foundation pit is of single slope type with a slope of 1:0.33. When the excavator digs to the place 20cm away from the design elevation, it is necessary to manually clean the bottom of the trench. Drainage ditches shall be reserved on both sides of the bottom of the trench to prevent the trench from soaking.
      2)豎向澆筑混凝土基礎
      2) Vertical pouring concrete foundation
      根據道路中心線,技術人員和施工人員共同確定管道位置中心線,然后設置兩側模具。模板采用新的模板。木模需要穩定的立姿和準確的標高,并設置10cm的礫石墊層。墊層對級配礫石表面無風化,基本光滑。基礎板采用C20混凝土澆筑。用平板振搗器對底板混凝土進行兩次振搗后,對底板混凝土進行抹平,并鋪上草袋進行養護。
      According to the center line of the road, technicians and constructors jointly determine the center line of the pipeline position, and then set the molds on both sides. The new template shall be adopted. The wooden formwork needs stable standing posture and accurate elevation, and 10cm gravel cushion is set. The cushion has no weathering on the surface of graded gravel and is basically smooth. The foundation slab is poured with C20 concrete. After two times of vibration of the bottom slab concrete with the plate vibrator, the bottom slab concrete shall be trowelled and covered with straw bags for maintenance.
      3)安裝管道,穩定鋼筋
      3) Installation of pipes, stabilizing reinforcement
      安全管采用機械下管,操作時應輕放,以免損壞底板。兩根管子的連接處應該用絞車拉緊。待管口基本齊平,調整好管底標高后,即可進行下一根管吊裝。

      The safety pipe shall be mechanically lowered, which shall be handled with care to avoid damage to the bottom plate. The connection between the two pipes should be tensioned by winch. After the pipe orifice is basically flush and the pipe bottom elevation is adjusted, the next pipe can be hoisted.
      4)鋼筋混凝土穩定澆筑
      4) Stable pouring of reinforced concrete
      管道吊裝完成后,將配筋穩定的混凝土同時倒入兩側豎向模內。
      After the completion of pipeline hoisting, the reinforced concrete shall be poured into the vertical formwork on both sides at the same time.
      5)和CMC
      5) and CMC
      所有CMC采用磚花園,Φ1000直徑。檢測井嚴格按照市設計院總圖施工。
      All CMC adopt brick garden, Φ 1000 diameter. The inspection well shall be constructed in strict accordance with the general drawing of the Municipal Design Institute.
      6)封閉水(污水管要求)
      6) Closed water (sewer requirements)
      檢查井完成,井口維護。
      Inspection well completed, wellhead maintenance.
      浸泡24小時后,封水試驗前無明顯滲漏現象。
      After soaking for 24 hours, there was no obvious leakage before water sealing test.
      7)、回填
      7), backfill
      回填應在水合格封閉后進行。首先將水箱中的水抽干,在有土地的地段用挖泥船將土壤挖至溝槽邊緣。在無土段,所有的土都要挖出,運至1公里外的溝邊平整,反復翻耕。回填土應由挖掘機回填。回填厚度應為30cm。當回填土達到一定高度時,采用壓路機壓實。
      Backfilling shall be carried out after the water is qualified and sealed. Firstly, the water in the water tank shall be drained, and the soil shall be excavated to the edge of the trench with a dredger in the land section. In the soilless section, all the soil shall be excavated and transported to the ditch 1 km away for leveling and repeated ploughing. The backfill shall be backfilled by excavator. The thickness of backfill shall be 30 cm. When the backfill reaches a certain height, the roller shall be used for compaction.
      1. 電力管道、信息管道走廊建設
      1. Power pipeline and information pipeline corridor construction
      1)測量放樣
      1) Survey and setting out
      根據施工單位提供的導線點和水準點,可以準確地確定基坑的開挖邊線,計算出基坑的開挖深度。
      According to the traverse points and benchmarks provided by the construction company, the excavation boundary of the foundation pit can be accurately determined and the excavation depth of the foundation pit can be calculated.
      2)溝開挖
      2) ditch excavation
      3)管道基礎
      3) Pipeline foundation
      在溝槽內無水的情況下,用墊層打好基礎混凝土,澆筑基礎混凝土,用板式振動器對基礎混凝土進行振動。
      When there is no water in the trench, the foundation concrete shall be laid with cushion, poured and vibrated with plate vibrator.
      4)管道工程
      4) Pipework
      5)動力井建設
      5) Power well construction
      6)管道走廊人孔施工
      6) Pipeline corridor manhole construction
      信息管走廊人孔井身采用磚砌體和混凝土樓板,現澆鋼筋混凝土環梁屋面。砌筑人孔時,應先將磚浸濕,砂漿飽滿,前磚墻澆水濕潤,抹灰面密實。蓋板的施工應符合《鋼精混凝土施工規范》的要求。
      The manhole shaft of information pipe corridor adopts brick masonry and concrete floor, and the cast-in-place reinforced concrete ring beam roof. When building manholes, the bricks shall be soaked first, the mortar shall be full, the front brick wall shall be watered and wetted, and the plastering surface shall be dense. The construction of the cover plate shall meet the requirements of the code for construction of steel precision concrete.
      7)溝渠回填
      7) Trench backfilling
      溝用土壓6%灰土回填多余的土方運輸。電夯應使用在井體及管溝周圍區域內分層,管溝兩側同時回填夯實,防止管材移位。溝槽回填順序按照溝槽排水方向由高到低分層。每一回填層厚度不得大于20cm,管溝頂采用50cm以上的輕型壓路機進行滾壓。
      The ditch shall be backfilled with 6% lime soil with earth pressure for redundant earthwork transportation. The electric rammer shall be used in layers around the well body and the pipe trench, and both sides of the pipe trench shall be backfilled and tamped at the same time to prevent pipe displacement. The backfilling sequence of the trench is from high to low layers according to the drainage direction of the trench. The thickness of each backfill layer shall not be greater than 20cm, and the top of the pipe trench shall be rolled with a light roller of more than 50cm.
