Document Type and Number:
WIPO Patent Application WO/2017/206411
Kind Code:
A1
Abstract:
A full-prefabricated superimposed assembly-type underground pipe gallery and a connection node thereof. A bottom plate of the underground pipe gallery is a prefabricated superimposed bottom plate (5), side walls or side walls and a middle wall are prefabricated sandwiched superimposed walls (3), and a top plate is a prefabricated superimposed plate (4). The bottom plate, the side walls or side walls and the middle wall, and the top plate are connected into an integral underground pipe gallery in a cast-in-situ mode. By means of prefabricating a part of the pipe gallery in factory and superimposing and casting the remaining in situ, the defects of low production efficiency and small freight volume of conventional prefabricated pipe galleries are overcome, and thus the purposes of template-free cast-in-situ construction, environmental protection, material saving, high quality and high efficiency are achieved, and the underground pipe gallery has desirable water-proof performance.
