水泥穩(wěn)定碎石的施工工藝和設備有哪些

來源:http://m.sybloom.com/ 日期:2025-02-15

  水泥穩(wěn)定碎石的施工工藝主要包括以下步驟:

  The construction process of cement stabilized crushed stone mainly includes the following steps:

  施工準備:

  Construction preparation:

  對原材料水泥、碎石、水進行質量檢驗,確保質量合格并做好備料工作。

  Conduct quality inspections on raw materials such as cement, crushed stone, and water to ensure they meet quality standards and prepare materials properly.

  由試驗室進行配合比試驗,確定混合料的最優(yōu)含水量和最大干密度,并報監(jiān)理批準。

  Conduct mix proportion tests in the laboratory to determine the optimal moisture content and maximum dry density of the mixture, and report to the supervisor for approval.

  對參與施工的現(xiàn)場管理人員、施工技術人員、作業(yè)人員進行技術交底和培訓。

  Provide technical briefing and training to on-site management personnel, construction technicians, and operators involved in construction.

  對下承層表面進行檢查和修補,清除浮土和雜物,整型壓實,確保表面平整、堅實,符合規(guī)定的高程、寬度、橫坡度。

  Inspect and repair the surface of the underlying layer, remove floating soil and debris, compact and shape it to ensure a smooth and solid surface that meets the specified elevation, width, and cross slope.

  對拌和站及攤鋪設備進行調試、檢查和保養(yǎng)。

  Debugging, inspection, and maintenance of mixing stations and paving equipment.

  根據路面干濕情況,如比較干燥則用水車霧狀噴灑,使工作面濕潤且無積水。

  According to the dry and wet conditions of the road surface, if it is relatively dry, use a water truck to spray in mist to keep the working surface moist and free of water accumulation.

  施工放樣:

  Construction layout:

  設置道路控制線,至少保證邊線、中線三條控制線。在直線段每10m設一個斷面控制點,曲線或彎段每5m設一個斷面控制點。

  Set up road control lines, ensuring at least three control lines: the edge line and the center line. Set a section control point every 10m in straight sections, and every 5m in curves or bends.

  攤鋪機施工選用Φ23mm的鋼絲作為基線,張拉長度100200m為佳,且須在兩端用緊線器同時張緊,避免因鋼絲不緊而產生撓度。

  The construction of the paving machine uses a Φ 23mm steel wire as the baseline, with a preferred tensioning length of 100200m, and must be tensioned simultaneously at both ends with a tensioner to avoid deflection caused by loose steel wire.

  水泥穩(wěn)定碎石拌合:

  Cement stabilized crushed stone mixing:

  在拌和站設置電子稱量儀并確保其合格。

  Install electronic weighing devices at the mixing station and ensure their compliance.

  在拌料前進行配合比的調試并進行試拌,確定各料倉的皮帶轉速,嚴格控制各料倉的材料用量。

  Before mixing, adjust the mix proportion and conduct trial mixing to determine the belt speed of each silo, and strictly control the material consumption of each silo.

  隨時觀察并檢測含水量,控制最佳含水量。若遇到大風和高溫天氣,應上調混合料的含水量1~2%,使混合料運到現(xiàn)場攤鋪后碾壓時含水量接近最佳含水量。

  Observe and monitor the moisture content at any time to control the optimal moisture content. If encountering strong winds and high temperatures, the moisture content of the mixture should be increased by 1-2%, so that the moisture content of the mixture when transported to the site for paving and rolling is close to the optimal moisture content.

  拌和站拌和混合料必須連續(xù)、均勻。

  The mixing station must mix the mixture continuously and evenly.

  混合料運輸:

  Transportation of mixed materials:

  采用自卸汽車運輸拌好的混合料,必要時加覆蓋以防水分蒸發(fā)。

  Transport the mixed material by dump truck and cover it if necessary to prevent water evaporation.

  運料設備要充足,確保拌和后的混合料能及時攤鋪。

  The material transportation equipment should be sufficient to ensure that the mixed material can be spread in a timely manner.

  卸料時,運料車在攤鋪機前方一定距離(如20~30cm)停車,防止碰撞攤鋪機。卸料速度與攤鋪速度相協(xié)調。

  When unloading, the transport vehicle should stop at a certain distance (such as 20-30 cm) in front of the paver to prevent collision with the paver. The unloading speed is coordinated with the paving speed.

  攤鋪整形:

  Laying and shaping:

  根據基層試驗段數(shù)據確定松鋪系數(shù),并及時根據實際情況調整。

  Determine the coefficient of loose paving based on the data from the grassroots experimental section and adjust it in a timely manner according to the actual situation.

  攤鋪過程中要保持攤鋪機的速度恒定,保證攤鋪機的夯錘或夯板的震搗頻率均勻一致。

  During the paving process, the speed of the paver should be kept constant to ensure that the vibration frequency of the paver's hammer or plate is uniform and consistent.

  攤鋪機攤鋪混合料時,因故中斷或一天的工作段結束時必須設置橫縫。

  When the paver is spreading the mixture, a transverse joint must be set at the end of the day or at the end of the working period due to unforeseen circumstances.

  碾壓:

  Rolling:

  選擇配備較大噸位的振動壓路機進行碾壓。

  Choose a vibratory roller with a larger tonnage for compaction.

  遵循初壓、輕振動碾壓、重振動碾壓、收面碾壓的程序進行。

  Follow the procedures of initial compaction, light vibration compaction, heavy vibration compaction, and finishing compaction.

  壓路機碾壓時應重疊1/2輪寬,速度控制在一定范圍內(如初壓1.51.7km/h,后續(xù)碾壓1.82.2km/h)。

  When the road roller is rolling, it should overlap by half the wheel width and control the speed within a certain range (such as initial rolling of 1.51.7km/h, subsequent rolling of 1.82.2km/h).

  嚴禁壓路機在剛完成的或正在碾壓的路段上調頭和急剎車。

  It is strictly prohibited for the road roller to turn around or apply sudden brakes on newly completed or rolling road sections.

  覆蓋養(yǎng)生:

  Coverage of health preservation:

  每一段碾壓完成并且壓實度經檢驗合格,強度初步形成后,即開始養(yǎng)生。

  After each section of rolling is completed and the compaction degree is inspected and qualified, and the strength is initially formed, the curing process begins.

  養(yǎng)生期間要保證基層保持濕潤狀態(tài),養(yǎng)生結束后將覆蓋物清除干凈。

  During the health preservation period, it is necessary to ensure that the grassroots is kept moist, and after the health preservation is completed, the covering should be removed completely.

  至于水泥穩(wěn)定碎石施工所需的設備,主要包括:

  As for the equipment required for cement stabilized crushed stone construction, it mainly includes:

  拌和設備:如WCB800型穩(wěn)定土拌合機,用于混合料的拌和。

  Mixing equipment: such as WCB800 stabilized soil mixer, used for mixing materials.

  運輸設備:如自卸汽車,用于混合料的運輸。

  Transportation equipment: such as dump trucks, used for transporting mixtures.

  攤鋪設備:如攤鋪機,用于混合料的攤鋪整形。

  Paving equipment: such as pavers, used for spreading and shaping mixtures.20230327054955655

  碾壓設備:如振動壓路機、雙鋼輪(或三鋼輪)壓路機、膠輪壓路機等,用于混合料的碾壓。

  Rolling equipment: such as vibratory rollers, double steel wheel (or triple steel wheel) rollers, rubber wheel rollers, etc., used for rolling mixtures.

  此外,還可能需要一些輔助設備,如灑水車(用于施工前的下承層濕潤和施工后的養(yǎng)生保濕)、測量放樣設備(如全站儀、緊線器、鋼絲繩等,用于施工放樣和標高控制)等。

  In addition, some auxiliary equipment may be required, such as sprinkler trucks (used for pre construction wetting of the underlying layer and post construction maintenance), measurement and layout equipment (such as total stations, tighteners, steel wire ropes, etc., used for construction layout and elevation control), etc.

  綜上所述,水泥穩(wěn)定碎石的施工工藝和設備是確保施工質量的關鍵要素。在施工過程中,應嚴格遵循施工工藝要求,選用合適的設備,并加強施工管理和質量控制,以確保施工質量和工程安全。

  In summary, the construction process and equipment of cement stabilized crushed stone are key elements to ensure construction quality. During the construction process, it is necessary to strictly follow the construction process requirements, select suitable equipment, and strengthen construction management and quality control to ensure construction quality and project safety.
