Description

Technical Field

[0001] This utility model relates to the field of concrete pipe gallery technology, specifically a U-shaped concrete pipe gallery outer mold with detachable reinforcing ribs. Background Technology

[0002] U-shaped concrete utility tunnels are concrete structure tunnels with a U-shaped cross-section design. They are mainly used in urban underground integrated utility tunnel projects. They are formed by factory prefabrication or on-site casting and are used to centrally lay municipal pipelines such as power, communication, water supply and drainage, so as to realize the intensive management of underground space.

[0003] Existing factory-prefabricated pipe sections offer controllable quality and high construction efficiency. The assembly error of the segments must be controlled within ±5mm, making joint treatment crucial. Commonly used methods include socket or bolt connections, supplemented by water-swellable sealing strips. While existing pipe sections are formed by pouring concrete into modules inside molds, disassembling these sections requires tools inserted into the connection between the mold and the pipe section, making disassembly cumbersome and time-consuming.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5The present invention provides the following technical solution:

[0027] A U-shaped concrete pipe gallery outer formwork with detachable reinforcing ribs includes a reinforcing device 1 and a sealing template 4. The inner wall surface of the sealing template 4 is fitted with a U-shaped concrete pipe gallery body 3. An inner template 2 is connected to the inner wall surface of the sealing template 4. An outer template 5 is connected to the surface of the U-shaped concrete pipe gallery body 3. The sealing template 4 is bolted to the inner wall surface of the reinforcing device 1.

[0028] The reinforcing device 1 includes a transverse reinforcing rib 11, and a longitudinal reinforcing rib 12 is bolted to the inner side surface of the transverse reinforcing rib 11. The outer formwork 5 is bolted to the inner side surface of the longitudinal reinforcing rib 12. The longitudinal reinforcing rib 12 is connected to the surface of the fastening threaded rod 14. The fastening threaded rod 14 connects the transverse reinforcing rib 11, the longitudinal reinforcing rib 12 and the outer formwork 5, thereby enhancing the stability of the outer formwork 5 and protecting the safety of the U-shaped concrete pipe gallery body 3.

[0029] The left and right ends of the transverse reinforcing rib 11 are connected to the release components 13, and the middle position of the transverse reinforcing rib 11 is connected to the fastening threaded rod 14. The fastening threaded rod 14 is connected to the front and rear ends of the inner formwork 2 and the front and rear ends of the outer formwork 5. The fastening threaded rod 14 locks and fixes the inner formwork 2, the U-shaped concrete pipe gallery body 3 and the outer formwork 5, and protects the stability of the U-shaped concrete pipe gallery body 3.

[0030] The detachment component 13 includes a metal vertical plate 131, which is bolted to the outer surface of the sealing template 4. The inner template 2 is connected to the inner wall surface of the U-shaped concrete pipe gallery body 3, and the outer template 5 is bolted to the inner wall surface of the sealing template 4. The bolts connect the inner template 2, the U-shaped concrete pipe gallery body 3, the sealing template 4, the outer template 5, and the metal vertical plate 131, thereby facilitating the molding of the U-shaped concrete pipe gallery body 3 and increasing the service life of the U-shaped concrete pipe gallery body 3.

[0031] An electric push rod 132 is bolted to the outer surface of the metal vertical plate 131. The piston rod inside the electric push rod 132 is connected to a connecting block 133. A threaded rod 134 is inserted into the outer end of the connecting block 133. The threaded rod 134 is inserted into the outer end of the electric push rod 132, and the threaded rod 134 locks and fixes the connecting block 133 and the electric push rod 132, thereby determining the position of the connecting block 133, facilitating the disassembly and replacement of the connecting block 133, and increasing the service life of the connecting block 133. A fastening bolt 135 is threaded to the inner end of the connecting block 133, and a metal horizontal plate 136 is connected to the surface of the fastening bolt 135.

[0032] A limiting block 137 is welded to the inner surface of the metal horizontal plate 136. The limiting block 137 is slidably connected to the inner surface of the metal vertical plate 131. A connecting block 133 is slidably connected to the front and rear ends of the metal vertical plate 131. An electric push rod 132 pushes the connecting block 133 to move back and forth. The connecting block 133 drives the limiting block 137 to move back and forth. The limiting block 137 drives the transverse reinforcing rib 11 to move back and forth, facilitating the disassembly of the transverse reinforcing rib 11 and the longitudinal reinforcing rib 12. The limiting block 137 is movably connected to the left and right ends of the outer template 5. The connecting block 133 is inserted into the upper and lower ends of the limiting block 137, and the fastening bolt 135 locks the limiting block 137 and the connecting block 133 in place, so that the connecting block 133 can drive the limiting block 137 to move back and forth. The metal horizontal plate 136 is movably connected to the left and right sides of the transverse reinforcing rib 11. The limiting block 137 is inserted into the left and right ends of the transverse reinforcing rib 11. The metal horizontal plate 136 at the bottom of the limiting block 137 is inserted into the left and right ends of the transverse reinforcing rib 11, thus connecting the limiting block 137 and the transverse reinforcing rib 11.

[0033] When in use, the inner formwork 2, sealing formwork 4 and outer formwork 5 can form the U-shaped concrete pipe gallery body 3 inside. It is necessary to disassemble the inner formwork 2, sealing formwork 4 and outer formwork 5 on the surface of the U-shaped concrete pipe gallery body 3.

[0034] Rotate the nut on the inner wall surface of the inner template 2. The nut disengages from the fastening threaded rod 14, loosening the connection between the fastening threaded rod 14 and the inner template 2.

[0035] The electric actuators 132 are activated. There are eight electric actuators 132 in total. Four electric actuators 132 form a group, and the two groups of electric actuators 132 are distributed in a front-to-back manner. The two groups of electric actuators 132 are controlled by a PLC controller, which allows the four electric actuators 132 in the same group to extend together.

[0036] The electric push rod 132 drives the connecting block 133 to move outward through the threaded rod 134. The connecting block 133 drives the limiting block 137 to move back and forth. The limiting block 137 drives the transverse reinforcing rib 11 to move back and forth through the metal horizontal plate 136.

[0037] When the transverse reinforcing rib 11 moves back and forth, the transverse reinforcing rib 11 pulls the fastening threaded rod 14 to move back and forth, allowing the fastening threaded rod 14 to slide inside the U-shaped concrete pipe gallery body 3 and the outer formwork 5, so that the fastening threaded rod 14 can disengage from the U-shaped concrete pipe gallery body 3 and the outer formwork 5.

[0038] The transverse reinforcing rib 11 pulls the longitudinal reinforcing rib 12 back and forth by bolts, so that the longitudinal reinforcing rib 12 pulls the outer formwork 5 by bolts, so that the outer formwork 5 is separated from the U-shaped concrete pipe gallery body 3, making the disassembly of the U-shaped concrete pipe gallery body 3 quick and convenient.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
