水泥穩(wěn)定碎石的施工工藝和設(shè)備有哪些

來(lái)源:http://www.mjcgs.com.cn/ 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(zhǔn)備:

  Construction preparation:

  對(duì)原材料水泥、碎石、水進(jìn)行質(zhì)量檢驗(yàn),確保質(zhì)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(yàn)室進(jìn)行配合比試驗(yàn),確定混合料的最優(yōu)含水量和最大干密度,并報(bào)監(jiān)理批準(zhǔn)。

  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(duì)參與施工的現(xiàn)場(chǎng)管理人員、施工技術(shù)人員、作業(yè)人員進(jìn)行技術(shù)交底和培訓(xùn)。

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

  對(duì)下承層表面進(jìn)行檢查和修補(bǔ),清除浮土和雜物,整型壓實(shí),確保表面平整、堅(jiān)實(shí),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(duì)拌和站及攤鋪設(shè)備進(jìn)行調(diào)試、檢查和保養(yǎng)。

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

  根據(jù)路面干濕情況,如比較干燥則用水車(chē)霧狀噴灑,使工作面濕潤(rùn)且無(wú)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(shè)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(shè)一個(gè)斷面控制點(diǎn),曲線或彎段每5m設(shè)一個(gè)斷面控制點(diǎn)。

  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(jī)施工選用Φ23mm的鋼絲作為基線,張拉長(zhǎng)度100200m為佳,且須在兩端用緊線器同時(shí)張緊,避免因鋼絲不緊而產(chǎn)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(shè)置電子稱量?jī)x并確保其合格。

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

  在拌料前進(jìn)行配合比的調(diào)試并進(jìn)行試拌,確定各料倉(cāng)的皮帶轉(zhuǎn)速,嚴(yán)格控制各料倉(cāng)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(shí)觀察并檢測(cè)含水量,控制最佳含水量。若遇到大風(fēng)和高溫天氣,應(yīng)上調(diào)混合料的含水量1~2%,使混合料運(yùn)到現(xiàn)場(chǎng)攤鋪后碾壓時(shí)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(yùn)輸:

  Transportation of mixed materials:

  采用自卸汽車(chē)運(yùn)輸拌好的混合料,必要時(shí)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(yùn)料設(shè)備要充足,確保拌和后的混合料能及時(shí)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(shí),運(yùn)料車(chē)在攤鋪機(jī)前方一定距離(如20~30cm)停車(chē),防止碰撞攤鋪機(jī)。卸料速度與攤鋪速度相協(xié)調(diào)。

  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(jù)基層試驗(yàn)段數(shù)據(jù)確定松鋪系數(shù),并及時(shí)根據(jù)實(shí)際情況調(diào)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(guò)程中要保持?jǐn)備仚C(jī)的速度恒定,保證攤鋪機(jī)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(jī)攤鋪混合料時(shí),因故中斷或一天的工作段結(jié)束時(shí)必須設(shè)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(dòng)壓路機(jī)進(jìn)行碾壓。

  Choose a vibratory roller with a larger tonnage for compaction.

  遵循初壓、輕振動(dòng)碾壓、重振動(dòng)碾壓、收面碾壓的程序進(jìn)行。

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

  壓路機(jī)碾壓時(shí)應(yīng)重疊1/2輪寬,速度控制在一定范圍內(nèi)(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(yán)禁壓路機(jī)在剛完成的或正在碾壓的路段上調(diào)頭和急剎車(chē)。

  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(shí)度經(jīng)檢驗(yàn)合格,強(qiáng)度初步形成后,即開(kāi)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(rùn)狀態(tài),養(yǎng)生結(jié)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(shè)備,主要包括:

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

  拌和設(shè)備:如WCB800型穩(wěn)定土拌合機(jī),用于混合料的拌和。

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

  運(yùn)輸設(shè)備:如自卸汽車(chē),用于混合料的運(yùn)輸。

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

  攤鋪設(shè)備:如攤鋪機(jī),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(shè)備:如振動(dòng)壓路機(jī)、雙鋼輪(或三鋼輪)壓路機(jī)、膠輪壓路機(jī)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(shè)備,如灑水車(chē)(用于施工前的下承層濕潤(rùn)和施工后的養(yǎng)生保濕)、測(cè)量放樣設(shè)備(如全站儀、緊線器、鋼絲繩等,用于施工放樣和標(biāo)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(shè)備是確保施工質(zhì)量的關(guān)鍵要素。在施工過(guò)程中,應(yīng)嚴(yán)格遵循施工工藝要求,選用合適的設(shè)備,并加強(qiáng)施工管理和質(zhì)量控制,以確保施工質(zhì)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.
