气泡混合轻质填土溶岩地区路基的填筑和泡沫混凝土实现建筑节能

发布时间:2019/3/26 12:31:22 浏览次数:32

我国许多地域处于溶岩散布区,公开溶洞多,散布的范围广且深度不等,溶洞的外表掩盖层多为软土层,承载才能小。在这些路段修建公路时,传统的施工法难于处理路堤根底的承载力缺乏(特别是高填土路堤)及经过大溶洞的桥梁桩基施工等难题。

Many areas in China are located in the karst dispersal area. There are many open karst caves, which spread widely and in varying depths. The outer cover layer of karst caves is mostly soft soil layer, so the bearing capacity is small. When constructing highways in these sections, it is difficult for traditional construction methods to deal with such problems as lack of bearing capacity of embankment foundation (especially high fill embankment) and construction of bridge pile foundation passing through large karst caves.

我省正在修建的某高速公路的某桥梁桩基处的钻孔柱状地质图,地表以下32.2~60.5米为溶洞,溶洞的上外表有近32米的掩盖层,且为软粘土与砂的夹层,原方案在此处修建的一座大桥,因思索到桥梁桩基施工的难度及施工过程中对其左近正在运营的公路桥梁桩基可能带来的负面影响,原修建桥梁的计划不得不改为填筑路基,但由于填土较高,采用常规的填土施工法可能呈现根底的承载力缺乏及软基的工后沉降大等问题;假如应用气泡混合轻质土来停止这段路基的施工,则能够较好地处理其它办法所无法处理的难题:将桥梁改为轻质路堤,原溶洞区域的桩基施工被取消;泡混合轻质土路堤的容重可调整到普通路堤的四分之一,可克制根底的承载力缺乏的问题;大幅度的减少路堤的工后沉降问题;工工期大大缩短。

The bored column geological map of the pile foundation of a bridge on a highway under construction in our province shows that 32.2-60.5 meters below the surface is a karst cave, and the upper surface of the cave has a cover layer of nearly 32 meters, and it is a sandwich between soft clay and sand. The original plan of a bridge built here considers the difficulty of the construction of the pile foundation of the bridge and the possibility of the pile foundation of the highway bridge being operated on the left and near in the construction process. The negative impact brought by the original bridge construction plan had to be replaced by filling roadbed, but due to the high filling, the conventional filling construction method may present problems such as the lack of bearing capacity of the foundation and the large settlement of the soft foundation after construction. If the construction of this roadbed is stopped by mixing light soil with air bubbles, the difficult problems that can not be solved by other methods can be solved better: changing the bridge into a new one. For the light embankment, the pile foundation construction in the original karst cave area has been cancelled; the volume weight of the foamed lightweight soil embankment can be adjusted to one fourth of the ordinary embankment, which can restrain the lack of bearing capacity of the foundation; greatly reduce the settlement of the embankment after construction; and greatly shorten the construction period.

随着泡沫混凝土在其它方面的应用逐渐推行,这一应用比例肯定会降落,但是仍会坚持较高的比例。从开展趋向看,泡沫混凝土在公开回填,挡土墙,渣滓掩盖,地基处置等工程方面的应用量将会日益扩展。它的这些方面的应用虽不 是提高性的,但由于工程量相当大,所以一旦推行,应用总量将很可观。随着泡沫混凝土应用技术的开发和提高,它的应用范围会逐年扩展,前景是非常美妙的。目前有机保温资料占整个保温资料市场的90%以上,这也是招致火灾高发的主要缘由。市场急切需求既节能又防火的建筑保温资料。

With the gradual application of foam concrete in other aspects, the proportion of this application will definitely drop, but it will still adhere to a higher proportion. From the perspective of development, the application of foam concrete in open backfill, retaining wall, trash cover, foundation treatment and other projects will be increasingly expanded. Although its application in these aspects is not improved, the total amount of application will be considerable once it is implemented because of the considerable amount of engineering. With the development and improvement of the application technology of foam concrete, its application scope will expand year by year, and the prospect is very wonderful. At present, organic thermal insulation materials account for more than 90% of the total thermal insulation data market, which is also the main reason for the high incidence of fire. The market urgently needs building thermal insulation materials which are energy-saving and fire-proof.

泡沫混凝土目前的应用虽广,但许多方面的应用仅是起步,大范围应用还需求一定的时间。从目前的实践范围化应用的状况看,它的主体性应用仍是建筑保温,其它方面的应用仍较少。泡沫混凝土应用全是为建筑节能效劳的。这阐明,淮南泡沫混凝土在目前和以后的相当长时期,都是以建筑保温为主。宏观背景来看,目前建筑节能占总能耗的30%,将来十年将超越工业成为第一大能耗行业,而选择节能降耗,平安环保的新型建筑资料尤为重要。“泡沫混凝土可应用于屋面,墙体和空中(地暖)保温等工程范畴,即可现场浇筑,又可与支撑各种制品,在完成建筑节能65%以上的同时,确保防火平安和运用寿命。”

Foam concrete is widely used at present, but the application in many aspects is only started. From the current situation of the application of the scope of practice, its main application is still building thermal insulation, other aspects of application is still less. The application of foam concrete is all for building energy efficiency. This shows that foam concrete is mainly in building insulation at present and for a long time. From the macro background, building energy saving accounts for 30% of total energy consumption. In the next ten years, it will surpass industry to become the largest energy consumption industry. It is particularly important to select new building materials with energy saving and environmental protection. "Foam concrete can be applied to roofing, wall and air (ground heating) insulation and other engineering areas, it can be poured on site, but also with support for various products, while achieving more than 65% of building energy efficiency, at the same time, ensure fire safety and service life."
