[0002] The underground pipe gallery is used for public tunnels for centralized laying of water, electricity, gas, communication and other municipal pipelines in the city. The existing underground pipe gallery is generally prefabricated with a square structure with openings on both sides. The steel cables are connected and tightened. The length of the steel cables is limited. An anchor groove will be set in the corner of the prefabricated pipe gallery for the connection and tightening of the steel cables. The tightening process is generally at the tail (or head) of the steel cables. ) to install the outer mold, the outer mold is equipped with a core mold, the inner ring of the core mold is set on the steel cable, the outer mold and the core mold are tightened by the inner taper surface, since the outer mold is set in the anchor groove, the length of the anchor groove Limited, the tightening angle is wrong when the external force is knocked, the tightening effect is not good, and the tail of the steel cable is easy to slip, causing water leakage and settlement of the pipe gallery, increasing maintenance costs and time, and needs to be improved

The invention discloses a wire rope fixing device for an underground pipe gallery. The wire rope fixing device comprises a support block, a pressing plate and an extrusion plate. The support block comprises a first contact plate, a support pipe and a second contact plate. An opening is formed below the support pipe along the axis. The first contact plate and the second contact plate are vertically arranged on the two sides of the support pipe. The pressing plate is arranged on one side of the first contact plate. The extrusion plate is arranged between the pressing plate and the first contact plate. The first contact plate, the support plate and the pressing plate are the same in size. A groove is formed bellow the first contact plate, the support block, the pressing plate and the second contact plate. The wire rope fixing device is simple and scientific in structure, callable of changing the stress direction, convenient to use, good in tightening effect, safe and reliable.
