[0054] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Combine the following Figure 1 The present invention describes a method for casting a prefabricated pipe gallery.

[0056] like Figure 1 As shown, the casting method of the prefabricated pipe gallery provided by the embodiment of the present invention comprises the following steps:

[0057] 110. Use the end surface of the second end of the first prefabricated pipe gallery that has been cast as an end mold, and cast the second prefabricated pipe gallery in the prefabrication area, and the end of the second prefabricated pipe gallery close to the first prefabricated pipe gallery is the first end of the second prefabricated pipe gallery;

[0058] 120. After the second prefabricated pipe gallery is cast, the first prefabricated pipe gallery is transported away from the prefabrication area;

[0059] 130. Separate the second end of the second prefabricated pipe gallery from the first end mold, and use the end surface of the second end of the second prefabricated pipe gallery as an end mold to cast the third prefabricated pipe gallery in the prefabrication area.

[0060] Specifically, the first prefabricated pipe gallery 6 is cast in advance, and then the end face of the second end of the first prefabricated pipe gallery 6 is used as the end mold for casting the first end of the second prefabricated pipe gallery 7, and the end face of the second end of the second prefabricated pipe gallery 7 is used as the end mold for casting the first end of the third prefabricated pipe gallery, and the cycle is repeated in sequence.

[0061] When assembling to form the integrated pipe gallery, the first end of the second prefabricated pipe gallery 7 is spliced ​​with the second end of the first prefabricated pipe gallery 6 , and the first end of the third prefabricated pipe gallery is spliced ​​with the second end of the second prefabricated pipe gallery 7 .

[0062] In this way, the assembly connection is carried out according to the prefabrication processing sequence, and during assembly, the two end faces of the adjacent prefabricated pipe corridors are ensured to be consistent with the two end faces matched during the pouring process, which can improve the matching degree between the adjacent prefabricated pipe corridors and enhance the water-stopping effect. This solves the problem of poor water-stopping effect caused by poor matching degree between adjacent prefabricated pipe corridors when assembling to form a comprehensive pipe corridor in the prior art.

[0063] In the embodiment of the present invention, the step of using the end surface of the second end of the cast first prefabricated pipe gallery as an end mold to cast the second prefabricated pipe gallery in the prefabrication area specifically includes:

[0064] 111. Assemble the end surface of the second end of the first prefabricated pipe gallery with the first end mold, a pair of side molds and a first bottom mold to form a first casting mold having a first mold cavity;

[0065] 112. Place the steel cage in the first cavity of the first casting mold and perform a casting operation;

[0066] 113. After the first pouring is completed, a set of inner molds are placed in the cabin of the steel cage to form a second pouring mold, and a second pouring is carried out.

[0067] That is, when the second prefabricated pipe gallery 7 is cast using the end face of the second end of the first prefabricated pipe gallery 6 , it is necessary to cooperate with the first end mold 1 , a pair of side molds 5 , the first bottom mold 2 and a group of inner molds 4 .

[0068] First, the end face of the second end of the first prefabricated pipe gallery 6, a pair of side molds 5 and the first bottom mold 2 are assembled to form a first casting mold, and the first casting mold has a first cavity inside, and the shape of the first cavity is consistent with the external shape and size of the second prefabricated pipe gallery 7.

[0069] Then the steel cage is hoisted into the first cavity of the first casting mold and cast once, wherein the casting once is to cast the bottom plate of the second prefabricated pipe gallery 7.

[0070] After the primary pouring is completed and the primary pouring part is initially solidified, a set of inner molds 4 are placed in the cabin of the steel cage, and the inner molds 4 are connected to the end molds to form a second pouring mold with the first pouring mold. Finally, the secondary pouring is performed, and the secondary pouring here is to pour the side panels and top panels of the second prefabricated pipe gallery 7.

[0071] It should be noted that the number of the inner molds 4 in the above group of inner molds 4 is consistent with the number of the compartments of the steel cage. After the primary casting part is initially solidified, each inner mold 4 can be placed one by one in the compartment of the steel cage.

[0072] In an embodiment of the present invention, the first prefabricated pipe gallery is supported by a second bottom mold. Before the first prefabricated pipe gallery is transported away from the prefabrication area, the following steps are also included:

[0073] 121. Separate a pair of side molds and a group of inner molds from the second prefabricated pipe gallery;

[0074] 122. Separate the end surface of the second end of the first prefabricated pipe gallery from the end surface of the first end of the second prefabricated pipe gallery, and separate the first prefabricated pipe gallery from the second bottom mold.

[0075] That is, before the first prefabricated pipe gallery 6 is transported away from the prefabrication area, the second prefabricated pipe gallery 7 needs to be demoulded and the first prefabricated pipe gallery 6 needs to be separated from the second bottom mold 3 .

[0076] Specifically, a pair of side molds 5 and a group of inner molds 4 can be separated from the second prefabricated pipe gallery 7 respectively, and then the second end of the first prefabricated pipe gallery 6 can be separated from the first end of the second prefabricated pipe gallery 7, and finally the first prefabricated pipe gallery 6 can be separated from the second bottom mold 3 thereunder.

[0077] After the first end of the first prefabricated pipe gallery 6 is separated from the first end of the second prefabricated pipe gallery 7 , the second end of the second prefabricated pipe gallery 7 can be separated from the first end mold 1 .

[0078] In the embodiment of the present invention, before the step of using the end face of the second end of the cast first prefabricated pipe gallery as an end mold and casting the second prefabricated pipe gallery in the prefabrication area, the prefabrication processing of the first prefabricated pipe gallery is also included, which specifically includes the following steps:

[0079] 1001. Assemble the second end mold with the first end mold, the second bottom mold and a pair of side molds to form a third casting mold having a first mold cavity;

[0080] 1002. Place the steel cage in the first cavity of the third casting mold and perform a casting operation;

[0081] 1003. After the first pouring is completed, a set of inner molds are placed in the cabin of the steel cage to form a fourth pouring mold, and a second pouring is performed.

[0082] Specifically, when casting the first prefabricated pipe gallery 6, it is necessary to use the second bottom mold 3 detached from the first prefabricated pipe gallery 6. In addition to the above-mentioned first end mold 1, second bottom mold 3, a pair of side molds 5 and a group of inner molds 4, it is also necessary to cooperate with the second end mold.

[0083] First, the second end mold, the first end mold 1, the second bottom mold 3 and a pair of side molds 5 are assembled to form a third casting mold, and the third casting mold has a first cavity inside, and the shape of the first cavity is consistent with the external shape and size of the first prefabricated pipe gallery 6.

[0084] Then the steel cage is hoisted into the first cavity of the third casting mold and cast once. The casting once here is casting the bottom plate of the first prefabricated pipe gallery 6.

[0085] After the primary pouring is completed and the primary pouring part is initially solidified, a set of inner molds 4 is placed in the cabin of the steel cage, and the inner molds 4 are connected to the end molds to form a fourth pouring mold with the third pouring mold. Finally, the secondary pouring is performed, and the secondary pouring here is to pour the side panels and top panels of the first prefabricated pipe gallery 6.

[0086] It should be noted that the first prefabricated pipe gallery 6, the second prefabricated pipe gallery 7 and the third prefabricated pipe gallery have the same structure and have the same number of cabins.

[0087] On the other hand, the embodiment of the present invention further provides a casting system for a prefabricated pipe gallery. Figures 2 to 9 , the casting system of the prefabricated pipe gallery provided by the present invention is described. The casting system of the prefabricated pipe gallery described below and the casting method of the prefabricated pipe gallery described above can refer to each other.

[0088] like Figures 2 to 9 As shown, an embodiment of the present invention provides a casting system for a prefabricated pipe gallery, including a mold assembly, a second end mold and a walking device. Specifically, the mold assembly includes a first end mold 1, at least two bottom molds, an inner mold 4 and a pair of side molds 5, wherein the number of the inner molds 4 is the same as the number of the cabins of the prefabricated pipe gallery. Figure 2 .

[0089] The second end mold can cooperate with the first end mold 1 , any one of the bottom molds, the inner mold 4 and a pair of side molds 5 for casting.

[0090] The walking device 8 is used to drive the bottom mold to move, and the position of the bottom mold is adjusted by the walking device 8 so that the bottom mold cooperates with the first end mold 1, the inner mold 4 and the side mold 5 for pouring, or drives the bottom mold away from the first end mold 1. This is beneficial to reduce the labor intensity of operators and improve work efficiency.

[0091] When the casting system of the prefabricated pipe gallery provided in this embodiment is used to cast and process the prefabricated pipe gallery, it is necessary to first use the second end mold and the first end mold 1, one of the bottom molds, the inner mold 4 and a pair of side molds 5 to cooperate to complete the casting of the first prefabricated pipe gallery 6.

[0092] The pouring process of the prefabricated pipe gallery is described by taking the case where two bottom molds are provided as an example. For the convenience of description, it is now stipulated that the bottom mold for pouring the first prefabricated pipe gallery 6 is the second bottom mold 3, the end of the first prefabricated pipe gallery 6 that matches the second end mold is the first end of the first prefabricated pipe gallery 6, and the end of the first prefabricated pipe gallery 6 that matches the first end mold 1 is the second end of the first prefabricated pipe gallery 6.

[0093] After the first prefabricated pipe gallery 6 is cast, demoulding is performed to separate the first prefabricated pipe gallery 6 from the second end mold, the first end mold 1, the inner mold 4 and the side mold 5. Then, the second bottom mold 3 and the first prefabricated pipe gallery 6 are driven by the walking device 8 to move in a direction away from the first end mold 1, so that the end surface of the second end of the first prefabricated pipe gallery 6 replaces the second end mold, cooperates with the first end mold 1, the first bottom mold 2, the inner mold 4 and a pair of side molds 5, and jointly completes the casting of the second prefabricated pipe gallery 7.

[0094] After the second prefabricated pipe gallery 7 is cast, demoulding is performed to separate the second prefabricated pipe gallery 7 from the side mold 5, the inner mold 4, the first prefabricated pipe gallery 6 and the first end mold 1. The first prefabricated pipe gallery 6 can be separated from the second prefabricated pipe gallery 7 by driving the second bottom mold 3 and the first prefabricated pipe gallery 6 away from the second prefabricated pipe gallery 7 through the walking device 8. The second prefabricated pipe gallery 7 can be separated from the first end mold 1 by driving the first bottom mold 2 and the second prefabricated pipe gallery 7 away from the first end mold 1 through the walking device 8. After the first prefabricated pipe gallery 6 is separated from the second prefabricated pipe gallery 7, the first prefabricated pipe gallery 6 is separated from the second bottom mold 3, and the first prefabricated pipe gallery 6 is transported away from the prefabrication area.

[0095] For the casting of the third prefabricated pipe gallery, it is necessary to move the second bottom mold 3 between a pair of side molds 5, and then drive the first bottom mold 2 and the second prefabricated pipe gallery 7 to move relative to the first end mold 1 through the walking device 8, so that the second end face of the second prefabricated pipe gallery 7 replaces the second end mold, and cooperates with the first end mold 1, the second bottom mold 3, the inner mold 4 and a pair of side molds 5 to complete the casting of the third prefabricated pipe gallery.

[0096] Similarly, the end face of the second end of the previous prefabricated pipe gallery is used as the end mold of the next prefabricated pipe gallery to cast the next prefabricated pipe gallery, and the two bottom molds are used in turn to cast the subsequent prefabricated pipe galleries.

[0097] During assembly, the assembly connection is performed according to the above pouring sequence, and during assembly, the two end faces of the adjacent prefabricated pipe corridors are ensured to be consistent with the two end faces matched during the pouring process, which can improve the matching degree between the adjacent prefabricated pipe corridors and enhance the water-stopping effect. This solves the problem of poor water-stopping effect caused by poor matching degree between adjacent prefabricated pipe corridors when assembling to form a comprehensive pipe corridor in the prior art.

[0098] In the embodiment of the present invention, the walking device 8 includes a first track 9, a first walking portion 10 and a telescopic support member 11. Figure 3 Specifically, the extension direction of the first track 9 is perpendicular to the plane where the first end mold 1 is located. The first walking part 10 can be connected to the bottom mold, and when it moves along the first track 9, it drives the bottom mold to move. The first track 9 can be a moving guide for the first walking part 10.

[0099] The telescopic support member 11 is arranged above the first walking part 10, and its length can be adjusted. When the position of the bottom mold needs to be moved, the telescopic support member 11 needs to be controlled to extend to lift the bottom mold off the ground. The bottom mold is supported on the telescopic support member 11, and the first walking part 10 moves along the first track 9, which can drive the bottom mold to approach or move away from the first end mold 1.

[0100] Specifically, the telescopic support member 11 can be one of a hydraulic cylinder, a pneumatic cylinder and an electric cylinder. The hydraulic cylinder, the pneumatic cylinder or the electric cylinder is arranged in a vertical direction and connected to a hydraulic circuit, a pneumatic circuit or an electric circuit. The action of the hydraulic cylinder, the pneumatic circuit or the electric circuit can be controlled by the hydraulic circuit, the pneumatic circuit or the electric circuit. The connection between the hydraulic circuit and the hydraulic cylinder, the structural principle of the hydraulic circuit, the connection between the pneumatic circuit and the cylinder, the structural principle of the pneumatic circuit, the connection between the circuit and the electric cylinder, and the structural principle of the circuit are all mature existing technologies and will not be elaborated here.

[0101] The first walking part 10 includes a base, a roller and a driving member. Specifically, the base is used to support the telescopic support member 11, and the roller is arranged on the base so as to be rotatable about a fixed axis. The driving member is arranged on the base, and the driving member is connected to the roller for driving the roller to rotate. The roller is supported on the first track 9, and when the roller rotates, it moves along the extension direction of the first track 9, thereby driving the base to move.

[0102] There are a plurality of the telescopic support members 11 , which are evenly distributed on the base, and there are a plurality of groups of rollers and driving members, which is beneficial for uniform force on the walking device 8 .

[0103] The driving member may be a hydraulic motor, which can convert liquid pressure into torque and speed of its output shaft. The output end of the hydraulic motor is connected to the roller transmission, which can drive the roller to rotate. An electric motor may also be used as the driving member, and the output end of the motor is connected to the roller transmission, thereby driving the roller to rotate.

[0104] In this embodiment, a support leg 12 is provided at the lower end of the bottom mold, and the length of the support leg 12 can be adjusted telescopically. When the telescopic support member 11 is extended to contact with the bottom mold, the length of the support leg 12 can be controlled to shorten, so that the support leg 12 of the bottom mold is out of contact with the ground, and the bottom mold is supported on the walking device 8.

[0105] The support leg 12 includes a fixed part and a movable part. The fixed part is connected to the bottom mold. A threaded hole with an axis in the vertical direction is provided on the fixed part. A screw that can be threadedly connected to the threaded hole is provided on the movable part. The threaded connection between the screw and the threaded hole realizes the threaded connection between the movable part and the fixed part. When the movable part is rotated, the movable part moves in the vertical direction, thereby realizing the extension and retraction of the support leg 12. The structure is simple and reliable, and the cost is low.

[0106] It should be noted that the above-mentioned walking device can be used when the base mold and the prefabricated pipe corridor located on the base mold are moved at the same time; when there is no prefabricated pipe corridor on the base mold, the base mold can be hoisted by a hoist to adjust the position of the base mold, and the base mold can also be moved by the above-mentioned walking device. At this time, it is necessary to set extension rails at both ends of the first rail 9 to form a closed-loop track with the first rail 9.

[0107] In the embodiment of the present invention, multiple groups of mold assemblies are arranged, and the number of second end molds can be the same as the number of mold assemblies, so that the second end molds correspond to the mold assemblies one by one, and each mold assembly simultaneously performs casting processing on the prefabricated pipe gallery.

[0108] The number of second end molds may also be smaller than the number of mold assemblies, or only one second end mold may be provided so that multiple groups of mold assemblies share one second end mold.

[0109] When only one second end mold is provided, the second end mold is first used in conjunction with the first group of mold components to cast the first prefabricated pipe gallery 6. After the first group of mold components casts the first prefabricated pipe gallery 6, the second end mold is no longer needed. The first group of mold components cooperates with the end face of the first prefabricated pipe gallery 6 to cast the subsequent prefabricated pipe gallery. Then, the second end mold is used in conjunction with the second group of mold components to cast the next first prefabricated pipe gallery 6. After the second group of mold components casts the first prefabricated pipe gallery 6, the second end mold is no longer needed. The second group of mold components cooperates with the end face of the first prefabricated pipe gallery 6 to cast the subsequent prefabricated pipe gallery. The second end mold is then cast in conjunction with the third group of mold components, and so on. Multiple groups of mold components share one second end mold, which reduces production costs.

[0110] A plurality of groups of mold assemblies are arranged in parallel, so that the inner molds 4 of the respective mold assemblies are parallel, and the respective first end molds 1 are located in the same plane.

[0111] When multiple groups of mold assemblies share the same second end mold, a moving device for driving the second end mold to move between each group of mold assemblies can be provided. Specifically, the moving device includes a fourth track and a third walking portion that can move along the fourth track. The fourth track is provided at an end of the side mold 5 away from the first end mold 1 and is perpendicular to each inner mold 4.

[0112] The fourth track intersects with the first track 9, and a rotating track is provided at the intersection between the fourth track and the first track 9. By rotating the rotating track, the rotating track can be docked with the fourth track, or with the first track 9. For those skilled in the art, the structure of the rotating track is a mature prior art and will not be described in detail herein.

[0113] The casting system of the prefabricated pipe gallery in the embodiment of the present invention also includes an inner mold installation assembly, which is used to drive the inner mold 4 to move in a direction perpendicular to the plane where the first end mold 1 is located, so as to facilitate the disassembly and assembly of the inner mold 4 on the casting mold.

[0114] Specifically, the inner mold installation assembly includes a second rail 13, a third rail 14 and a second walking portion 15, wherein the second rail 13 is arranged on the side of the first end mold 1 away from the side mold 5, and the extension direction of the second rail 13 is perpendicular to the plane where the first end mold 1 is located, that is, the extension direction of the second rail 13 is consistent with the extension direction of the inner mold 4. After the bottom plate portion of the prefabricated pipe gallery is cast, the third rail 14 is arranged above the bottom plate, so that the third rail 14 is coaxially docked with the second rail 13, and the end of the third rail 14 is detachably connected to the second rail 13.

[0115] The movement and installation of the third rail 14 can be completed by lifting with a lifting tool or the like. The detachable connection between the third rail 14 and the second rail 13 can be achieved by providing a flange at the end of the third rail 14 and the second rail 13 close to each other, providing a mounting hole on the flange, and using bolts and nuts to achieve the connection between the second rail 13 and the third rail 14.

[0116] The second walking part 15 is connected to the inner mold 4, and the second walking part 15 can move along the second track 13 and the third track 14. By docking the end of the third track 14 with the second track 13, the second walking part 15 can reciprocate on the second track 13 and the third track 14, thereby driving the inner mold 4 to move.

[0117] Before pouring, the inner mold 4 is supported on the second rail 13 via the second running part 15 .

[0118] When installing the inner mold 4, first dock the third rail 14 with the second rail 13, and extend the third rail 14 to the second end mold or the cabin space of the first prefabricated pipe gallery. Then, the second walking part 15 is used to drive the inner mold 4 to move from the second rail 13 to the third rail 14, and the inner mold 4 is connected to the end mold after moving to the corresponding position.

[0119] After demoulding, before the preform is transported away, the second walking part 15 is used to drive the inner mold 4 to move to the second track 13, and then the third track 14 is taken out to complete the removal of the inner mold 4.

[0120] The inner mold installation assembly avoids direct handling and hoisting of the inner mold 4 during installation and removal of the inner mold 4. The third rail 14 is smaller in weight and appearance than the inner mold 4. Compared with the moving and transporting of the inner mold 4, the moving and transporting of the third rail 14 can reduce the labor intensity of the workers. The gap between the third rail 14 and the steel cage cabin space is large, and the second rail 13 and the third rail 14 are arranged to guide the second walking part 15, which reduces the difficulty of the inner mold 4 entering the steel cage cabin space, enables the inner mold 4 to quickly enter the steel cage cabin space, and improves the installation efficiency.

[0121] When casting the first prefabricated pipe gallery 6, the two ends of the third rail 14 can be supported on the first end mold 1 and the second end mold respectively. When casting the second prefabricated pipe gallery 7 and subsequent prefabricated pipe galleries, one end of the third rail 14 can be supported on the first end mold 1, and the other end can be supported on the bottom plate of the previous prefabricated pipe gallery. Figure 4 and Figure 5 .

[0122] Specifically, a leg 16 can be arranged on the third track 14, the leg 16 is perpendicular to the third track 14, one end of the leg 16 is connected to the third track 14, and the other end can be supported on the end mold or the bottom plate of the previous prefabricated pipe gallery. The leg 16 is arranged at both ends of the third track 14, and the length of the leg 16 can be adjusted telescopically. By adjusting the length of the leg 16, the horizontality of the third track 14 can be adjusted to ensure the installation accuracy of the inner mold 4.

[0123] A support assembly 17 is also provided on the third rail 14. The length of the support assembly 17 is adjustable. By adjusting the length of the support assembly 17, the support assembly 17 can be supported on the surface of the cabin of the prefabricated part. When the second end mold is removed, the support assembly 17 is used to support the third rail 14 on the surface of the cabin of the prefabricated part, so that the legs 16 are out of contact with the second end mold, thereby making the second end mold out of contact with the prefabricated part, so as to realize demoulding of the second end mold.

[0124] It should be noted that, for those skilled in the art, the structures of the first end mold 1, the second end mold, the bottom mold, the inner mold 4 and the side mold 5 are all mature existing technologies and will not be described in detail here. The movement of the inner mold 4 can also be achieved by lifting and moving it with a sling, and is not limited to being achieved by the inner mold 4 installation system.

[0125] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
