る。After this, sacrificial concrete is poured to form the root cut bottom surface 47, one end of the separator 49 is fixed to the exposed surface of the steel core material 45 by welding, etc.
A flame-retardant heat insulating material is sprayed onto the inner wall surface 51 of the inner wall 1, and a smooth outer heat insulating material N53 of a constant thickness is formed in close contact with the inner wall surface 51 of the inner wall surface 51.
次に、外側断熱層５３の内側に、第３図に示すように、

Fresh concrete is poured in this area, and the inner insulation 15
An underground outer wall 65 of the underground structure 63 is formed in close contact with the underground structure 7 .

。Therefore, in the external insulation/external waterproofing method for underground external walls of the present invention, after forming a ridge 14 underground 67 and removing earth from the inside of this ridge 41, on the inner wall surface 51 of the ridge 14, Since the heat insulation layer 53, the waterproof layer 55, and the inner heat insulation layer 57 are formed in close contact with each other in this order, and the underground outer wall 65 is constructed in close contact with the inside thereof, the outer heat insulation layer 53, the waterproof layer 55, and the inner heat insulation layer 57 functions as a heat insulating material and a waterproofing material for the underground outer wall 65, and prevents leakage and inundation of underground water penetrating the underground outer wall 65 of the underground structure 63 and the underground outer wall 65.
It is possible to reliably prevent condensation from forming on the inner surface.
すなわち、従来、地下構造物６３の全部あるいは一部が

漏水，浸水等の防水を確実に行なうことが可能となる。That is, in the past, when all or part of the underground structure 63 was located at a depth below the permanent level L of underground water, there was a risk that the groundwater would penetrate the underground outer wall 63 and leak or flood indoors if only the insulation layer was used. In the present invention, the outer heat insulating layer 53, the waterproof layer 55, and the inner heat insulating layer 57 are in close contact with the inner wall surface 51 of the lock 41.
Since the continuous waterproof layer 55 is formed, it becomes possible to reliably waterproof against underground water leakage, flooding, etc.

ることが可能となる。In addition, conventionally, the insulation performance of insulation materials located at depths below the permanent level L of groundwater deteriorates significantly due to absorption of groundwater, and there is a risk that the effect of preventing condensation on the inside of the underground outer wall 65 of the underground structure 63 may be lost. However, in the present invention, since the waterproof layer 55 is disposed between the outer heat insulating layer 53 and the inner heat insulating layer 57, moisture is not absorbed into the inner heat insulating layer 57, and moisture is absorbed inside the underground outer wall 65. It becomes possible to reliably prevent dew condensation from occurring.

分に確保することが可能となる。In addition, in general, pile-stopping method 4 using the soil pile column method
The exposed surface after scraping off the soil pile 43 in No. 1 becomes a rough surface with many unevenness, so even if you try to form a coating layer by directly spraying waterproofing material on this surface, it will not be uniform in thickness etc. Although it has been difficult to form a good waterproof layer, in the present invention, the outer heat insulating layer 53 is formed in a manner that eliminates the unevenness of the exposed surface of the soil bail ζ3 of the mountain stopper 41, and this outer heat insulating layer 53 is formed on the inside of Ii53. Since the waterproof layer 55 is formed on a smooth surface, it is possible to sufficiently ensure homogeneity and continuity of the waterproof layer 55.

水層５５の破壊が防止され、防水性能を十分に確保する
ことが可能となる。Conventionally, when a waterproof layer is formed by closely contacting the exposed surface of the soil pile 43, the soil pile 43
Alternatively, if some displacement occurred in the steel core material 45, there was a risk that the waterproof layer would break, but in the present invention, the outer heat insulating layer 5
3 is interposed between the exposed surface of the soil pile 43 and the waterproof layer 55, this outer heat insulating layer 53 acts as a buffer material, so even if the retainer 41 is displaced, the waterproof layer 55 Destruction is prevented and waterproof performance can be sufficiently ensured.
さらに、本発明では、従来の外断熱工法のように、外側
断熱層５３，防水層５５および内側断熱Ｎ５７の形成の
ための特別な作業空間を設ける必要がなくなり、土地の
有効利用を図ることが可能となる。Furthermore, in the present invention, there is no need to provide a special work space for forming the outer heat insulating layer 53, waterproof layer 55, and inner heat insulating layer N57, unlike the conventional external heat insulation method, and the land can be used more effectively. It becomes possible.

As a result, the outer heat insulating layer 53,
It becomes possible to easily form the waterproof layer 55 and the inner heat insulating layer 57.

水工法では、地中に山止めを形成し、この山止めの内側
を排土した後、山止めの内壁面に、外側断熱層，防水層
，内側断熱層を順次密着して形成し、さらにその内側に
密着して地下外壁を構築するようにしたので、地下構造
物の地下外壁を貫通しての地下水の漏水，浸水、および
、地下外壁内面への結露の発生を確実に防止することが
できる．
また、請求項２の地下外壁の外断熱・外防水工法では、
請求項１において、外側断熱層および内側断熱層を断熱
材の吹付けまたは発泡材の現場発泡により形成し、防水
層を防水材の吹付けにより塗膜状に形成するようにした
ので、現場において外側断熱層，防水層および内側断熱
層を容易に形成することができるという利点がある。As described above, in the external insulation/external waterproofing method for underground external walls according to claim 1, after forming a pile in the ground and removing earth from the inside of this pile, external insulation insulation is applied to the inner wall surface of the pile. By forming layers, waterproofing layers, and inner insulation layers in close contact with each other in order, and constructing the underground outer wall by adhering to the inner side of the layers, there is no leakage or flooding of underground water that penetrates the underground outer wall of the underground structure. In addition, it is possible to reliably prevent condensation from forming on the inner surface of the underground outer wall. In addition, in the external insulation/external waterproofing method for underground external walls according to claim 2,
In claim 1, the outer heat insulating layer and the inner heat insulating layer are formed by spraying a heat insulating material or foaming a foam material on-site, and the waterproof layer is formed in the form of a coating film by spraying a waterproof material. There is an advantage that the outer heat insulating layer, the waterproof layer and the inner heat insulating layer can be easily formed.
