The objective is to provide a ground insulation method that not only improves frost heaving prevention performance but also has good work efficiency.

遂には地盤が破壊されるＫいたる。°When the temperature drops below 0℃ in winter in cold regions,
Water in the ground freezes, and the growth of ice crystals causes the ground to lift unevenly, causing cracks to form. Furthermore, as the temperature rises, ice crystals melt from the surface side, resulting in a significant decrease in the supporting capacity of the surface layer.
Eventually, the ground will be destroyed.

えない。Can be mentioned. Among these methods, the replacement method involves replacing the subgrade soil within the frozen depth with a material that is less likely to cause frost heave, and there are problems with excavation time and disposal of leftover soil. Additionally, chemical treatment methods that lower the freezing temperature by adding cryogens such as calcium chloride, and methods that lower the groundwater level by installing drainage channels are ineffective unless the construction is done on a relatively large scale and carefully. However, it has various drawbacks, such as the fact that even if it is temporarily effective, it does not last for a long period of time, so it cannot be said to be a fundamental frost heaving prevention method.

となっている。On the other hand, the insulation method involves providing a heat insulating layer between the surface layer and the ground or roadbed to prevent outside air temperature from being conducted underground and to prevent underground moisture from freezing. As this method, a method is known in which a foamed plastic molded plate is used to form a heat insulating layer. This method involves building a sand layer on the roadbed that has been lowered to a depth of 10 tM to 100 crn underground, then laying out foamed plastic molded boards, spreading sand again on top of this, and then applying roadbed material such as crushed stone on top of it. The pavement is finished with asphalt, concrete, etc. However, with this method, it is essential to provide a sand layer on top of the molded board because the foamed plastic molded board is susceptible to misalignment during construction and is easily damaged by the sharp edges of the stones. be. Furthermore, cutting and joining operations are required to suit the shapes of drainage ditches, exposed pipes, manholes, etc. in the excavated roadbed, making the actual operations extremely complex.

が格段に優れている。As shown in Slanted Top, the ground insulation method of the present invention uses amorphous insulation material, so there are no gaps when it is laid like the conventional construction method, and the insulation performance of the material is effectively demonstrated. This provides excellent frost heaving prevention effects. Furthermore, when constructed using a spraying machine, the work efficiency is much higher than that of conventional construction methods.
以下実施例により本発明を詳述する。The present invention will be explained in detail with reference to Examples below.

した以外は、実施例１と同様にして施工した。[Example 3] In Example I, a foamed silica insulation material was used instead of Cell P-Sfiber, and the area density of spraying was increased to Tokyo/
■ [Example 4] A mixture of 20% cement and cellulose fiber was mixed with cellulose fiber at 15% by spraying machine. Construction was carried out in the same manner as in Example 1, except that water was sprayed at the same time as spraying at an area density of rrl, and the thickness of the heat insulating layer after rolling was 4 crn.
〔実施例５〕
セルロースファイバーと鉱滓綿とを７；３の割合に混合
したものを使用した以外は、実施例１と同様にして施工
した。[Example 5] Construction was carried out in the same manner as in Example 1, except that a mixture of cellulose fiber and mineral wool in a ratio of 7:3 was used.
以上の実施例に於いて、施工作業性はいずれも優れてい
た０尚、施工３日経過後サンプリングのために掘削した
ところ、断熱層には亀裂はみられず、断熱性能も良好で
あった〇In all of the above examples, construction workability was excellent. Furthermore, when we excavated for sampling after 3 days of construction, no cracks were found in the insulation layer, and the insulation performance was good.
