摘要： Disclosed is a chimney access structure which is particularly well adapted for use in grounds subject to freezing. This structure incorporates chimney provided with an upper end on which is mounted an adaptor provided with a vertical through-hole and with a countersink hole of greater diameter that the through-hole. The countersink hole is preferably frusto-conical and extends coaxially within the through-hole at a given depth from the upper face of the adaptor. This countersink hole defines a sleeve with upper portion of the adaptor which is provided with an inwardly projecting flexible sealing ring. A floating head is slidably mounted into the sleeve. This head has a vertical through-hole coaxial with the one of the adaptor. The floating head also has a lower portion provided with an outer lateral surface whose shape and size are selected to fit into the countersink hole of the adaptor and sealingly slide within the same thanks to the sealing ring. A cover-supporting frame and a chimney access cover are fixed on top of the floating head. Thanks to its structure, this chimney access does not suffer from any of the problems presently encountered with the existing chimney access structures, such as unwanted infiltration or jamming of the floating head due to an accumulation of granulates or to a lateral deflection thereof that may occur when the ground is freezing and thawing.
摘要翻译：公开了一种烟囱进入结构，其特别适用于在冷冻的地面中使用。该结构包括设置有上端的烟囱，其上安装有具有垂直通孔的适配器，并具有与通孔更大直径的埋头孔。埋头孔优选是截头圆锥形的，并且在适配器的上表面的给定深度处在通孔内同轴地延伸。该埋头孔限定了具有适配器的上部的套筒，该套筒设置有向内突出的柔性密封环。浮动头可滑动地安装在套筒中。该头部具有与适配器之一同轴的垂直通孔。浮动头还具有设置有外侧表面的下部，其外形和尺寸被选择为适合于适配器的埋头孔，并且由于密封环而在其内密封地滑动。盖支撑框架和烟囱通道盖固定在浮动头的顶部。由于其结构，这种烟囱进入不会受到现有烟囱进入结构目前遇到的任何问题的影响，例如由于颗粒积聚引起的浮动头的不期望的渗透或卡住或其可能发生的横向偏转当地面冻结融化。

摘要： A method for manufacturing, transporting and installing on a building site a prefabricated structure made of reinforced concrete for the replacement of a structure such as a manhole, access chamber, access vault, junction box or other, which is buried in the ground and is part of an underground network such as a sewer, aqueduct, gas, electrical distribution, telecommunications, cable television and the like. In this method, concrete is poured in factory against the external surfaces of an integrated removable handling system, which is used as top part of a mold for manufacturing the prefabricated structure. The handling system is fixed to the prefabricated structure in a removable manner. The handling system remains in place during the subsequent steps of unmoulding, transporting and installing the prefabricated structure to the building site. Finally, once the installation is completed, the handling system is removed from the structure.
