小型混凝土攪拌機在泵送混凝土結構中的局限性

在小型民用建筑工地上，通?？梢钥吹叫⌒突炷翑嚢柢?，二次拌和穩(wěn)定土攪拌站但是混凝土攪拌車給我們帶來了施工方便和一些局限性

On small civil construction sites, we can usually see small concrete mixer and secondary mixing stabilized soil mixing plant, but the concrete mixer has brought us construction convenience and some limitations

1.除了滿足工程質(zhì)量要求外，混凝土的配合比還應滿足管道運輸?shù)囊?。例如，對于坍落度，混凝土骨料的大粒徑以及水泥和細骨料的比例有一定的限?以農(nóng)村公路建設為例,對于水泥路的建設，通常對使用的水泥量有要求,每米使用的水泥量為4-6包。水泥路需要由車輛駛過，該車輛太小,水泥不具有粘結作用，水泥過多產(chǎn)生的道路太弱而無法承受滾動，并且匹配的混凝土需要能夠經(jīng)受住混凝土攪拌車的要求的測試。

1. In addition to meeting the project quality requirements, the mix proportion of concrete shall also meet the requirements of pipeline transportation. For example, for slump, the large particle size of concrete aggregate and the proportion of cement and fine aggregate are limited Take rural road construction as an example. For the construction of cement road, there are usually requirements for the amount of cement used, and the amount of cement used per meter is 4-6 bags. The cement road needs to be driven by a vehicle. The vehicle is too small, the cement does not have bonding effect, the road generated by too much cement is too weak to bear rolling, and the matched concrete needs to be able to withstand the test required by the concrete mixer.

2.混凝土的輸送距離受輸送管的直徑，混凝土攪拌車分配閥的性能和出口壓力的限制。盡管混凝土攪拌車的遠距離送給施工方省去了很多麻煩，但送距離和送壓力仍然受到限制。普通混凝土攪拌車具有特定的大抽油距離和大垂直抽油。高度。超出此范圍，則需要移動混凝土攪拌車或更換。

2. The conveying distance of concrete is limited by the diameter of the conveying pipe, the performance of the distribution valve of the concrete mixer and the outlet pressure. Although the long-distance delivery of concrete mixer to the construction party saves a lot of trouble, the delivery distance and pressure are still limited. Ordinary concrete mixer truck has specific large pumping distance and large vertical pumping. Height. Beyond this range, the concrete mixer needs to be moved or replaced.

3.混凝土攪拌車操作人員需要具有一定的技術水平，不僅要掌握機械的使用和維護方法，還要了解混凝土施工技術的一些知識，并能夠判斷混凝土的質(zhì)量和可送性。

3. The operators of concrete mixer truck need to have a certain technical level, not only master the use and maintenance methods of machinery, but also understand some knowledge of concrete construction technology, and be able to judge the quality and delivery of concrete.

4.混凝土攪拌車難以運輸干燥的硬質(zhì)混凝土，這限制了混凝土攪拌車的使用范圍。這是目前混凝土攪拌車的局限性，也是未來的創(chuàng)新方向。如果混凝土攪拌車制造商能夠獨立開發(fā)能夠輸送干燥硬質(zhì)混凝土的混凝土攪拌車，那么它將是整個混凝土攪拌車行業(yè)的突破限制5。溫度低于-5℃時，需采取特殊措施。

4. It is difficult for concrete mixer truck to transport dry hard concrete, which limits the application scope of concrete mixer truck. This is not only the limitation of concrete mixer at present, but also the innovation direction in the future. If the concrete mixer manufacturer can independently develop a concrete mixer capable of conveying dry and hard concrete, it will be a breakthrough limit for the whole concrete mixer industry 5. When the temperature is lower than - 5 ℃, special measures shall be taken.
