水穩(wěn)攤鋪施工過程需要注意的事項(xiàng)

來源：http://apdetong.cn/ 日期：2023-06-19

濟(jì)南水穩(wěn)料開始拌合前，拌合場(chǎng)的備料應(yīng)滿足3~5天的攤鋪用料。每天開始攤鋪前，應(yīng)檢查場(chǎng)內(nèi)各處集料的含水量，計(jì)算當(dāng)日的配合比，外加水與天然含水量的總和要比佳含水量略高1個(gè)百分點(diǎn)。

Before the mixing of Jinan water stabilized materials, the preparation of materials at the mixing plant should meet the paving requirements of 3-5 days. Before starting paving every day, the moisture content of the aggregates in various parts of the site should be checked, and the mix ratio for that day should be calculated. The total amount of added water and natural moisture content should be slightly higher than the optimal moisture content by 1 percentage point.

每天開始攪拌之后，出料要檢查是否符合設(shè)計(jì)配合比，進(jìn)行正式生產(chǎn)之后，每1~2小時(shí)檢查一次拌合情況，抽檢其配合比、含水量是否變化。高溫作業(yè)時(shí)，早晚與中午的含水量要有區(qū)別，要按溫度變化及時(shí)調(diào)整。

After starting mixing every day, the discharge should be checked for compliance with the designed mix ratio. After formal production, the mixing condition should be checked every 1-2 hours, and the mix ratio and water content should be randomly checked for any changes. During high-temperature operations, there should be a difference in water content between morning and evening and noon, and adjustments should be made in a timely manner according to temperature changes.

拌合機(jī)出料不允許采取自由落地、裝載機(jī)裝料運(yùn)輸?shù)霓k法，采用由漏斗出料直接裝料運(yùn)輸。裝車時(shí)車輛應(yīng)前后移動(dòng)，分三次裝料，避免混合料離析。

The method of free landing and loading and transportation by loader is not allowed for the discharge of the mixer, and direct loading and transportation by funnel discharge is adopted. When loading, the vehicle should move forward and backward, loading in three stages to avoid segregation of the mixture.

一、攤鋪前應(yīng)將下層適當(dāng)灑水潤(rùn)濕。二、混合料運(yùn)至施工現(xiàn)場(chǎng)后，采用攤鋪機(jī)攤鋪的方法按照掛設(shè)的高程控制線進(jìn)行攤鋪。三、掌握好松鋪厚度與壓實(shí)后厚度的關(guān)系，進(jìn)而嚴(yán)格控制好水穩(wěn)層的壓實(shí)厚度和高程，確保壓實(shí)厚度滿足設(shè)計(jì)要求。好是配備基于北斗定位的智能攤鋪系統(tǒng)，可以大大提高工程質(zhì)量以及降低人工成本。

1、 Before paving, the lower layer should be properly moistened with water. 2、 After the mixture is transported to the construction site, it is spread using a paver according to the elevation control line set up. 3、 Master the relationship between the loose paving thickness and the compacted thickness, and strictly control the compacted thickness and elevation of the water stable layer to ensure that the compacted thickness meets the design requirements. The good thing is to equip an intelligent paving system based on Beidou positioning, which can greatly improve project quality and reduce labor costs.

混合料攤鋪時(shí)采用兩個(gè)工作面梯隊(duì)作業(yè)，一前一后應(yīng)保證速度一致、攤鋪厚度一致、松鋪系數(shù)一致、路拱橫坡一致、攤鋪平整度一致、振動(dòng)頻率一致等。攤鋪時(shí)注意接縫平整。在攤鋪時(shí)每個(gè)工作面應(yīng)設(shè)專人消除混合料離析現(xiàn)象，特別要鏟除局部粗集料“窩”，并用新混合料填補(bǔ)。嚴(yán)格按照交底控制攤鋪寬度，超寬或者不夠?qū)?，追究施工單位及現(xiàn)場(chǎng)管理人員的責(zé)任。

When paving the mixture, two working faces are used in a cascade operation. The first and the second should ensure consistent speed, paving thickness, loose paving coefficient, crown slope, paving smoothness, and vibration frequency. Pay attention to the smoothness of the joints during paving. During paving, a dedicated person should be assigned to each working surface to eliminate the phenomenon of mixture segregation, especially to remove local coarse aggregate "pits" and fill them with new mixtures. Strictly control the paving width according to the disclosure, and hold the construction unit and on-site management personnel responsible for exceeding or not exceeding the width.
