Description

A vertical shock absorption underground pipe gallery

technical field

The utility model belongs to the technical field of construction, in particular to a vertical shock-absorbing underground pipe gallery.

Background technique

The underground pipe gallery, also known as the underground comprehensive pipe gallery, is built in the city underground for the centralized laying of electric power,

For public tunnels of municipal pipelines such as communications, radio and television, and water supply, the underground pipe gallery can effectively eliminate the phenomenon of "zipper road", so that technicians do not need to repeatedly excavate the road surface, and can repair, maintain and expand various pipelines in the pipe gallery. At the same time, it has been widely used in the field of urban construction; although there are some prefabricated underground pipe gallery structures on the market, these structures are assembled on-site and installed underground. After digging a deep pit, put the assembled pipe gallery into the deep pit and then backfill. This process is the longest method currently used. The disadvantage is that the construction period is long, the equipment and manpower are used, and the impact on the surrounding buildings is relatively large. The existing prefabricated underground pipe gallery includes a tubular body, the two ends of the tubular body are respectively provided with mutually matching insertion ends and socket ends, and the four corners of the tubular body are provided with installation holes parallel to the axial direction of the tubular body. Hanging rings are arranged on the left front side, right front side, left rear side and right back side of the top of the tubular body; when the existing prefabricated underground pipe gallery is used, the tubular body is hoisted by the hanging rings, and the insertion ends of a group of tubular bodies are inserted into To the socket end of the other group of tubular bodies, connect the multiple groups of tubular bodies, pass the four groups of steel strands through the installation holes at the four corners of the multiple sets of tubular bodies, connect and fix the multiple sets of tubular bodies, and finally pour concrete The joints of adjacent tubular bodies are sealed; in the use of the existing prefabricated underground pipe gallery, it is found that due to the large volume and weight of a single group of tubular bodies, it brings difficulties to the transportation, hoisting and insertion of the tubular bodies. The large difficulty increases the construction difficulty and construction cost; and due to the complex underground environment, the tubular bodies are easily affected by stress and temperature, causing the joints of the tubular bodies to crack, resulting in poor sealing effect; Various pipelines or pipes are installed. Because they are installed in a limited underground space, large-diameter prefabricated pipes are generally used for the water supply and drainage pipes.
