近些年來,機制砂的使用在我國大大小小的建設項目中隨處可見,這在前些年是不可想象的,機制砂生產工藝復雜,且含泥量大,遠遠不如天然砂開采后經過簡單的加工就可以使用來的便捷。造成這種局面的原因皆是因為前些年對于天然砂的過度開采使得目前我國的天然砂資源逐漸殆盡,水土流失現象日漸嚴重,為了改善現狀有關部門開始了對天然砂的開采的加強管控,而作為替代品的機制砂因為這些年的生產技術進步,含泥量大的弊端也得到了有效改善,因此逐漸取而代之也就理所當然了。那么,目前機制砂在我國的現代化建設中又具體有哪些應用呢?下面,洗砂機廠家給您進行一下盤點。

      一、建筑工程施工。

      在建筑工程施工中,砂石骨料一直是必不可少的重要原材之一,不管是作為滲水性填料,還是直接用于房屋、隧道、路基、橋梁等的施工中,砂的用量都比較大。如此大的砂石用量,如果是采用遠程運輸的形式進行原料的采購,那肯定會因為昂貴的造價而提高了整個工程的成本,而如果采用就近生產的方式,肯定能大大的降低原料成本。如果附近的天然砂比較匱乏,或者是砂石的配比質量達不到工程要求,那就可以考慮采用硬質山巖經過爆破和初步加工以后,利用制砂機制成一定顆粒級配的機制砂,這樣將大大提高工程效率,減少成本。

      二、高速公路鋪設。

      高速公路屬于高等級公路,為了適應工業化和城市化的發展,我國的高度公路建設一直是重要關注的重點項目,高速公路建設主要是從城市的環路、輻射路和交通繁忙路段開始,逐步的建成以高速公路為骨干的城市交通網絡。因此,混凝土用砂量在原有每年較大幅度增長趨勢下更是陡增,但我國有較多地區天然砂數量已近耗盡,而采取機制砂代替原有天然砂已經成為了大多數項目的選擇。

      三、水利建設。

      出了高速公路的建設外,我國目前對水利建設的關注投入同樣重視,水利建設作為我國的現代化基礎建設之一,一直在不斷地推進。大規模的水利建設同樣是需要大量砂石骨料的,機制砂作為目前應用為廣泛的砂石骨料同樣在水利建設中的使用也不會少。

      四、高鐵建設。

      除了以上介紹的之外,高速鐵路的建設無疑發展的更為迅猛,在近幾年,我國已經新增的多條的高鐵項目已經成功運行,這預示這我國將走進高鐵時代,居民的遠距離出行將更為的便捷。而高鐵的建設是離不開砂石骨料,高速鐵路的建設需要大量的砂子和石子,而現如然砂資源的減少,這對于高鐵建設來說,機制砂石原料將是一中非常好的替代品。

In recent years, the use of machine-made sand can be seen everywhere in large and small construction projects in China, which is unimaginable in the previous years. The production process of machine-made sand is complex, and the mud content is large, which is far less convenient than that of natural sand after simple processing. The reason for this situation is that the overexploitation of natural sand in previous years has gradually exhausted the natural sand resources in our country, and the phenomenon of soil erosion has become increasingly serious. In order to improve the current situation, the relevant departments of the state began to strengthen the management and control of the exploitation of natural sand, and the mechanism sand, as the only alternative, because of the progress of production technology in these years, has the disadvantages of large mud content When it comes to effective improvement, it's natural to gradually replace it. So, what are the specific applications of machine-made sand in China's modernization? Next, the manufacturer of the sand washing machine will make an inventory for you.
I. construction works.
In the construction of construction engineering, sand aggregate has always been one of the essential raw materials. Whether it is used as water permeable filler or directly in the construction of houses, tunnels, subgrade, bridges, etc., the amount of sand is relatively large. If such a large amount of sand and stone is purchased in the form of long-distance transportation, the cost of the whole project will certainly be increased because of the high cost, and if the way of nearby production is adopted, the cost of raw materials will be greatly reduced. If there is a lack of natural sand nearby, or the ratio quality of sand and stone can not meet the requirements of the project, then it can be considered to use the hard rock after blasting and preliminary processing, and use the sand making mechanism to form a certain particle grading machine-made sand, which will greatly improve the efficiency of the project and reduce the cost.
II. Expressway laying.
Expressway belongs to high-level highway. In order to adapt to the development of industrialization and urbanization, the construction of high-level highway in China has always been a key project of national attention. The construction of Expressway mainly starts from the ring road, radial road and busy traffic section of the city, and gradually builds the urban traffic network with expressway as the backbone. Therefore, the amount of sand used for concrete is increasing sharply under the trend of large annual growth, but the amount of natural sand in many areas of our country is nearly exhausted, and the replacement of the original natural sand with machine-made sand has become the choice of most projects.
3. Water conservancy construction.
In addition to the construction of expressways, China pays equal attention to the investment in water conservancy construction. As one of China's modern infrastructure, water conservancy construction has been continuously promoted. Large scale water conservancy construction also needs a lot of sand and stone aggregate, and machine-made sand, as the most widely used sand and stone aggregate, is also used in water conservancy construction.
4. High speed railway construction.
In addition to the above, the construction of high-speed railway is undoubtedly developing more rapidly. In recent years, many new high-speed railway projects in China have been successfully operated, which indicates that China will enter the era of high-speed railway, and the long-distance travel of residents will be more convenient. The construction of high-speed railway is inseparable from sand and stone aggregate. The construction of high-speed railway needs a lot of high-quality sand and stone. Now, the natural sand resources are reduced, which is a very good substitute for high-speed railway construction.
