Description

Technical Field

[0001] The utility model relates to the technical field of tunnel casting, in particular to a tunnel casting pipeline system. Background Art

[0002] With economic development and convenient transportation, more and more tunnels are being built. However, during the tunnel construction process, the construction process of the tunnel is to first do initial support, then lay a waterproof layer, and then use a trolley to support the formwork so that there is a casting space between the formwork and the waterproof layer (each formwork generally has three casting ports on both sides), and then cast into the casting space.

[0003] The existing casting system corresponding to the trolley includes a main casting pipe, which first casts the tunnel side A, then moves to the B side for casting; specifically, taking the casting of side A as an example, the worker controls the casting pipe to cast from the first template and the casting port from bottom to top, and then pulls the casting to cast the next template. This method has the following defects: 1. The casting pipe needs to be docked with each template six times (three times on the A side and three times on the B side), and the casting operation cannot be performed during the switching of the casting port, thus restricting the casting efficiency.

[0004] To this end, we designed a tunnel casting pipeline system that can simultaneously cast on both sides of the formwork. Utility Model Content

[0005] In order to overcome the deficiencies in the background technology, the utility model discloses a tunnel casting pipeline system.

[0006] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0007] A tunnel casting pipeline system comprises a main casting pipe, wherein a three-way plate valve is provided at the discharge end of the main casting pipe, and both discharge ends of the three-way plate valve are connected to branch casting pipes;

[0008] The three-way plate valve comprises a valve body, a feed connector is provided at the bottom of the valve body, discharge connectors are provided on both sides of the valve body, a valve plate capable of blocking any discharge connector is rotatably connected to the middle of the valve body, and a driving motor for driving the valve plate to rotate is provided on the outer side of the valve body;

[0009] Wherein, a stop block is provided on the inner wall of the valve body corresponding to a position between the discharge connector and the feed connector, and the outer end of the valve plate is correspondingly located on a side of the two stop blocks away from the feed connector.

[0010] Preferably, it also includes a fixed pipe arranged on the side of the template and connected to the three casting ports on the side of the template.

[0011] Preferably, the fixed pipeline includes a main pipeline, and the main pipeline is connected with three fixed branches at intervals from top to bottom, and the lowest fixed branch is connected to the lower end of the main pipeline, and the outer ends of the three fixed branches are connected one by one with the three casting ports on the corresponding sides of the template.

[0012] Preferably, the fixed branch pipe is arranged to be inclined up and down, and the end corresponding to the main pipe is the upper end.

[0013] Preferably, a flexible stopper is provided on the inner wall of the valve body at a side of the discharge connector away from the feed connector, so as to prevent the outer end of the valve plate from moving back and forth.

[0014] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0015] 1. Compared with the prior art, a three-way plate valve and a branch casting pipe are added, so that the casting pipeline system has two discharge ports. The two discharge ports correspond to the casting ports of the template on the same side, realizing the function of simultaneous casting on both sides, thereby improving the casting efficiency;

[0016] 2. The specific structure of the three-way plate valve can be set so that when the driving motor is not running, the concrete transported by the main casting pipe enters the valve body. Under the impact of the concrete, the valve plate swings to the side away from the feed joint, so that the two discharge joints are in a state of passage, so that the two branch casting pipes can work at the same time; the driving motor can also drive the valve plate to be blocked by the corresponding blocking block, so that the corresponding discharge joint is cut off from the passage by the valve plate, and does not affect the other discharge joint in the state of passage, so that the driving motor only needs a low-priced motor with forward and reverse functions to complete the above functions, thereby reducing the production cost as much as possible;

[0017] 3. The setting of the fixed pipeline enables the support casting pipe to complete the casting operation of the side template only by docking once, thereby greatly improving the casting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. to indicate directions or positional relationships, they only correspond to the drawings of the present application, in order to facilitate the description of the present invention; it should be understood that if there are terms such as "end", "side", "end part", "lateral", "lateral", "transverse", "longitudinal", etc. to indicate directions or positional relationships, they only correspond to the length and width of the corresponding parts, that is, "end part" indicates the head and tail areas in the length direction of the corresponding part, and "side part" indicates the head and tail areas in the width direction of the corresponding part; this is for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction.

[0026] Embodiment 1, in combination with the attached Figure 1-6 A tunnel casting pipeline system includes a main casting pipe 1, a three-way plate valve 2 is provided at the discharge end of the main casting pipe 1, and both discharge ends of the three-way plate valve 2 are connected to branch casting pipes 3; compared with the prior art, this arrangement adds the three-way plate valve 2 and the branch casting pipe 3, so that the casting pipeline system has two discharge ports, and the two discharge ports correspond to the template casting port on the same side, thereby realizing the function of simultaneous casting of both sides, thereby improving the casting efficiency.

[0027] The three-way plate valve 2 comprises a valve body 21, a feed connector 22 is provided at the bottom of the valve body 21, discharge connectors 23 are provided on both sides of the valve body 21, a valve plate 24 capable of blocking any of the discharge connectors 23 is rotatably connected to the middle of the valve body 21, and a driving motor 25 for driving the valve plate 24 to rotate is provided on the outer side of the valve body 21;

[0028] A stop block 26 is provided on the inner wall of the valve body 21 at a position corresponding to the position between the discharge connector 23 and the feed connector 22 , and an outer end of the valve plate 24 is located at a side of the two stop blocks 26 facing away from the feed connector 22 .

[0029] During use, when the driving motor 25 is not running, the concrete transported by the main casting pipe 1 enters the valve body 21, and under the impact of the concrete, the valve plate 24 swings to the side away from the feed joint 22, so that the two discharge joints 23 are in a state of passage, so that the two branch casting pipes 3 can operate at the same time; when one of the branch casting pipes 3 needs to replace the casting port, the driving motor 25 can be started so that the driving motor 25 drives the valve plate 24 to move toward the discharge joint 23 corresponding to the branch casting pipe 3 until the valve plate 24 is blocked by the corresponding blocking block 26. At this time, the discharge joint 23 corresponding to the branch casting pipe 3 is cut off from passage by the valve plate 24, and does not affect the other discharge joint 23 from being in a state of passage.

[0030] It should be noted that the driving motor 25 only needs to be a low-priced motor with forward and reverse functions to complete the above functions, thereby reducing the manufacturing cost as much as possible.

[0031] Embodiment 2, combined with the attached Figure 1-6 , a tunnel casting pipeline system. Since there are three casting ports on each side of the template, each branch casting pipe 3 in the first embodiment needs to be docked three times to complete the casting operation of the side template; to further improve the casting efficiency; this embodiment, based on the first embodiment, also includes a fixed pipe 4 arranged on the side of the template and connected to the three casting ports on the side of the template.

[0032] The fixed pipeline 4 includes a main pipeline 41, which is connected to three fixed branches 42 at intervals from top to bottom, and the lowest fixed branch 42 is connected to the lower end of the main pipeline 41, and the outer ends of the three fixed branches 42 are connected one by one to the three casting ports on the side of the corresponding template.

[0033] Specifically, the upper end of the main pipe 41 has a joint connected to the branch casting pipe 3. Since there are many joint structures in the prior art that can realize detachable connection between two pipes, the joint will not be described in detail here.

[0034] This arrangement allows casting after the branch casting pipe 3 is connected to the upper end of the main pipeline 41. At this time, concrete will be cast in sequence from the bottom to the top of the fixed branch pipe 42. Therefore, the branch casting pipe 3 can complete the casting operation of the side formwork after only one connection, thereby greatly improving the casting efficiency.

[0035] As required, the fixed branch pipe 42 is arranged to be tilted up and down, and the end corresponding to the main pipe 41 is the upper end.

[0036] Embodiment 3, in combination with the attached Figure 1-6 A tunnel casting pipeline system, based on the first or second embodiment, in order to prevent the valve plate 24 from shaking back and forth in the valve body 21 when not in operation, a flexible stopper 27 is provided on the inner wall of the valve body 21 at the side of the discharge joint 23 away from the feed joint 22.

[0037] As required, the flexible stopper 27 can be a convex point or a convex layer made of rubber material, and its main function can be to play a blocking role, or to increase the friction between the valve plate 24 and the inner wall of the valve body 21, thereby preventing the valve plate 24 from moving back and forth.

[0038] Specifically, an installation groove is provided on the inner wall of the valve body 21 at a position corresponding to the flexible stopper 27, and the flexible stopper 27 is fixedly installed in the installation groove, and the outer end of the flexible stopper 27 extends out of the installation groove; specifically, the flexible stopper 27 can be compressed into the installation groove under the strong squeezing of the valve plate 24, so that the valve plate 24 can pass over the flexible stopper 27 under the impact of the driving motor 25 and the material.

[0039] It should be noted that the outer end of the valve plate 24 can be a curved plate that matches the inner port of the discharge connector 23. Figure 6 , which can be a flat plate matching the inner port of the discharge connector 23, refer to 3-5; the two methods have their own advantages and disadvantages. The valve plate 24 with an arc-shaped plate at the outer end is more difficult to manufacture than the valve plate 24 with a flat plate at the outer end. However, the service life of the valve plate 24 with an arc-shaped plate at the outer end is longer than that of the valve plate 24 with a flat plate at the outer end. The specific design is based on actual needs and is not specifically limited here.

[0040] As needed, the branch casting pipe 3 can be a flexible pipe throughout, that is, the shape can be slightly changed as needed; the branch casting pipe 3 can also have an inner section close to the three-way plate valve 2 as a hard pipe and an outer section as a flexible pipe. The specific setting is based on actual conditions and is not specifically limited here.

[0041] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
