Technical Field

The invention belongs to the technical field of building construction, and particularly relates to a novel assembly type underground pipe gallery.

Background

The utility model relates to a comprehensive pipe gallery (Japan called 'common ditch', Taiwan called 'common pipeline'), namely an underground city pipeline comprehensive corridor, namely, a tunnel space is built underground, various engineering pipelines such as electric power, communication, gas, heat supply, water supply and drainage and the like are integrated, a special overhaul port, a lifting port and a monitoring system are arranged, unified planning, unified design, unified construction and management are implemented, and the utility model is an important infrastructure and a 'lifeline' for guaranteeing city operation. Utility tunnel should divide into trunk utility tunnel, branch utility tunnel and cable piping lane. The main line comprehensive pipe gallery is used for accommodating a comprehensive pipe gallery constructed by city main engineering pipelines in an independent cabin division mode. The branch comprehensive pipe gallery is a comprehensive pipe gallery which is used for accommodating urban distribution engineering pipelines and is constructed in a single-cabin or double-cabin mode. The cable pipe gallery is built in a shallow-buried channel mode, is provided with an openable cover plate, but the inner space of the openable cover plate cannot meet the normal passing requirement of personnel, and is used for accommodating the power cables and the communication cables. The utility tunnel system not only solves the problem of urban traffic jam, but also greatly facilitates the maintenance and overhaul of municipal facilities such as electric power, communication, gas, water supply and drainage and the like. In addition, the system also has a certain shockproof and disaster reduction effect. For example, in 1995, during the great earthquake of Osaka, Japan, a large number of houses in the Shenhu city collapse and roads are damaged, but most of local underground comprehensive pipe galleries are intact, so that the difficulty of post-earthquake disaster relief and reconstruction work is greatly reduced. The utility tunnel plays an important role in meeting the basic demands of the civilian life and improving the comprehensive bearing capacity of the city.

The construction of the common ditch avoids the influence and interference on traffic and resident trip caused by frequently digging roads for laying and maintaining underground pipelines, and keeps the road appearance complete and beautiful. The cost of repeated repair of the road surface and the maintenance cost of the engineering pipeline are reduced. The integrity of the pavement and the durability of various pipelines are maintained. Is convenient for laying, increasing, decreasing, maintaining and daily managing various pipelines. Because the pipeline arrangement is compact reasonable in the ditch, effectively utilized the space under the road, practiced thrift urban land.

But current assembled underground pipe gallery still has the structure complicacy to lead to the concatenation installation inconvenient, connects insecure security performance lower and the longer problem of construction cycle.

Disclosure of Invention

In order to solve the technical problems, the invention provides a novel assembly type underground pipe gallery to solve the problems that the existing assembly type underground pipe gallery is inconvenient to splice and install, not firm in connection, low in safety performance and long in construction period due to complex structure.

The technical scheme adopted by the invention is as follows:

the invention discloses a novel assembled underground pipe gallery, which comprises: the pipe gallery comprises a pipe gallery body, a first pipe gallery piece and a second pipe gallery piece, wherein a rectangular bulge and a triangular bulge are arranged at the lower part of the first pipe gallery piece, an outer extending rib is arranged on the rectangular bulge, and reserved main rib holes are formed in two sides of the rectangular bulge; the upper part of the second pipe gallery piece is provided with a rectangular groove and a triangular groove, the rectangular groove is provided with a reserved main rib hole, and two sides of the rectangular groove are provided with outer extending ribs;

a rectangular groove is reserved on the pipe gallery piece, and reinforcing steel bar holes are formed at two ends of the rectangular groove reserved on the pipe gallery piece; the length and width of the rectangular steel plate are consistent with those of the reserved rectangular grooves on the pipe gallery pieces, and reinforcing steel bar holes are formed in the two ends of the rectangular steel plate;

inner side thickening blocks are arranged inside the first pipe gallery piece and the second pipe gallery piece, and tensioning holes are formed in the middle positions of the inner side thickening blocks;

the external extending ribs are matched and spliced with the reserved main rib holes, and the external extending ribs are fixed at the rectangular main rib connecting openings; the rectangular steel plate is placed on the pipe gallery piece, and the first pipe gallery piece, the second pipe gallery piece and the rectangular steel plate are connected into a pipe gallery body through the joint connecting ribs; after the adjacent pipe gallery bodies are matched with the sockets through the sockets, the steel strands are tensioned through the tensioning holes and then fixed through an anchorage device.

Further, bellmouth and socket set up respectively in the left and right sides both ends of piping lane body.

Furthermore, the rectangular protrusion and the triangular protrusion are respectively matched with the rectangular groove and the triangular groove.

Furthermore, the waterproof sealing gasket is glued on the inner side of the socket or the spigot.

Further, the waterproof roll material layer is glued to the connecting surface of the adjacent pipe gallery bodies.

Furthermore, the diameter of the tensioning hole is 5mm-8 mm.

The invention has the beneficial effects that:

the invention has the advantages of simple assembly operation, convenient construction, reduced labor intensity of operators, convenient transportation, greatly shortened construction period, firm connection part, safe and reliable structure and stronger waterproof sealing performance.
