很多人会对我们房子上的那些优美的EPS线条而好奇,他们的应用原理是什么呢?为什么会那么优美漂亮呢?这些都是大家心中的疑惑,原谅小编卖个关子,今天小编给大家带来的就是关于咱们杭州临安田园eps线条为什么会那么优美,为什么会那么漂亮,为什么会让这么多人喜欢,哈哈哈有点自恋了,不过这些都是咱们用实力证明的,今天杭州田园EPS线条就您讲解一下!

1 铺设EPS隔热层、防治路基冻害

在多年冻土地区修筑道路将会引起局部环境的改变,导致多年冻土的融化,使道路产生严重的病害甚至破坏。传统的整治冻害方法如垫板、注盐、换土、铺炉渣等方法效果都不理想。

由于EPS材料中内壁气泡为封闭状,互不相通,吸水率小,抗冻性好,保证了在浸水条件下仍具有良好的隔热性能。青藏公路昆仑山越岭地段EPS板隔热路基试验(1990)研究表明,6cm厚的EPS隔热层可减少地表向深层的热流量,减小地下多年冻土层上限的下移,可减缓多年冻土层的冻融,保持线路结构的稳定和减小变形。该研究成果在楚玛河引道、红梁河桥桥头引道及老温泉地区等路段得到了推广应用。从工程现状看,路面坚实平整,路基稳定,路基、路面整体强度满足设计要求。

2 减小路基沉降、防止或处治路基失稳

在软土地基上修筑路堤,因为普通填料密度大,其自重产生的地基附加应力较大,常会造成路基过大的不均匀沉降和沉降量。由于EPS密度小,具有超轻质特性,在进行一定深度的换填后可有效减小路堤自重,降低地基附加应力,减少软土地基路堤沉降,提高地基的稳定性。填筑10m高的EPS路堤大约相当于10cm高的低填土路堤荷载,路堤荷重大大减小,因此在斜坡地段修筑EPS路堤可有效防止滑坡产生,提高高路堤的抗滑稳定性。

EPS施工不需特殊机械,人力即可施工,速度快,适用于抢险救灾,对于大型机械难以使用的场所更适合,可现场加工切割,以适应场地地形要求。甬台温高速公路台州段一期工程K42+650~K42+800段,1998年8月软土路基施工中因填筑过快,造成路基滑塌,地面上拱60cm。由于工期十分急迫,现场受104国道及外侧厂房的限制,最终选用EPS轻质材料填筑路堤,最厚处为6层,最薄处为1层填筑,共计用量为7295m3,同年10月填筑完毕。该路段自1998年底建成通车至今,沥青混凝土路面平整,使用状况良好。

3 防止桥头跳车、减小桥台的侧向位移

由于桥头(桥台与路基交界处)位置的特殊性,路基填筑施工质量难于控制,并且桥台与路堤结构的差异,使得在桥头处容易产生不均匀沉降, 这对道路寿命、行车舒适性和安全性影响极大。减小或控制桥头处的差异沉降是在软基上修建路堤的难题。由于EPS自重极轻,将其用作桥头处的填料,可有效地减小沉降差;同时因其自立性好,也可大幅减小路堤对桥台的侧向压力,减小桥台的侧向位移。

经过杭州eps线条厂家给您的倾情介绍,大家对EPS线条的应用有了更深刻的理解和认识,希望能帮到你哦!

A lot of people will be curious about those beautiful EPS lines on our house, what is their application principle? Why is it so beautiful? These are all in the heart of doubt, forgive small make up selling imprison son, small make up bring you today is about our hangzhou linan rural eps line why so beautiful, why would be so beautiful, why so many people like, ha ha ha a little narcissism, but these are we prove that, with the strength today hangzhou rural eps line would you explain!

Lay EPS insulation layer to prevent roadbed frostbite

The construction of road in permafrost region will cause the change of local environment, lead to the thawing of permafrost, and cause serious disease or even damage to the road. The traditional methods such as plate, salt injection, soil change and slag laying are not ideal.

Due to the closed air bubbles in the inner wall of EPS material, which are not intercommunicated with each other, the absorption of water is small, and the frost resistance is good, which ensures the good heat insulation performance under the condition of immersion. According to the study of EPS plate thermal insulation roadbed test (1990) in the crossing section of kunlun mountain of qinghai-tibet highway, the 6cm thick EPS thermal insulation layer can reduce the heat flow from the surface to the deep layer, reduce the upper limit of the underground permafrost, slow down the freezing-thawing of the permafrost layer, maintain the stability of the line structure and reduce the deformation. The results of this study have been applied in chuma river approach, hongliang river bridge approach and old hot spring area. From the current engineering situation, the road surface is solid and smooth, the roadbed is stable, and the overall strength of roadbed and road meets the design requirements.

Reduce subgrade settlement, prevent or treat subgrade instability

Because of the high density of the common packing, the additional stress of the foundation caused by its self-weight is large, which often causes the uneven settlement and settlement of the roadbed. Due to the low density of EPS and its super lightweight characteristics, it can effectively reduce the dead weight of embankment, reduce the additional stress of foundation, reduce the settlement of embankment on soft soil foundation and improve the stability of foundation after a certain depth of filling. The construction of EPS embankment with a height of 10m is approximately equivalent to the load of low-filled embankment with a height of 10cm, which greatly reduces the embankment load. Therefore, the construction of EPS embankment in the slope section can effectively prevent landslide and improve the anti-slip stability of high embankment.

EPS construction does not need special machinery, manual construction, fast, suitable for rescue and disaster relief, for large machinery is difficult to use more suitable for the site processing cutting, to adapt to the site terrain requirements. Section K42+650~K42+800 of phase I project of taizhou section of yongtaiwen expressway. In August 1998, too fast filling of soft subgrade caused the subgrade to collapse and 60cm arch on the ground. Due to the urgency of the construction period, the site was limited by the 104 national highway and the outer workshop, so EPS lightweight material was finally selected to fill the embankment, with the thickest part being 6 layers and the thinnest part being 1 layer, with a total consumption of 7295m3. The construction was completed in October of the same year. Since the end of 1998, the asphalt concrete road has been smooth and in good condition.

Prevent the bridge head from jumping and reduce the lateral displacement of the abutment

Due to the particularity of the position of bridge head (abutment and roadbed junction), the construction quality of roadbed filling is difficult to control, and the difference of bridge abutment and embankment structure makes it easy to produce uneven settlement at the bridge head, which has a great impact on road life, traffic comfort and safety. Reducing or controlling differential settlement at bridge head is a difficult problem in building embankment on soft foundation. Because EPS has very light weight, it can be used as filler at the bridge head to reduce the settlement difference effectively. At the same time, the lateral pressure of embankment on abutment can be greatly reduced and the lateral displacement of abutment can be reduced.
