Description

Technical Field

[0001] The present application relates to the field of prefabricated buildings, and in particular to a prefabricated pipe gallery. Background Art

[0002] An underground comprehensive pipeline corridor is a public tunnel built underground in a city for the centralized laying of municipal pipelines such as electricity, communications, radio and television, and water supply.

[0003] In order to improve construction efficiency, current pipeline corridors usually adopt the method of on-site splicing of multi-segment square cast-in-place culverts. Since the weight and space occupation of a single segment of the culvert are very large, the transportation and lifting of the culvert require large vehicles, which makes on-site construction inconvenient. Summary of the invention

[0004] In order to improve the inconvenience of pipe gallery construction, the present application provides a prefabricated pipe gallery.

[0005] The prefabricated pipe gallery provided in this application adopts the following technical solution:

[0006] A prefabricated pipe gallery comprises side frames and plate beams, wherein two side frames are provided and two plate beams are provided, the two plate beams are located between the two side frames and correspond to the top and bottom ends of the side frames respectively, a groove is provided on one side where the end of the side frame and the plate beam abut against each other, a channel steel is embedded in the groove, grouting pipes corresponding to the channel steels are pre-buried in the plate beams, the grouting pipes are connected to the channel steels through a first branch pipe, both ends of the grouting pipes are connected to a second branch pipe, and the second branch pipes are upwardly connected to the outside of the plate beam.

[0007] By adopting the above technical scheme, during assembly, concrete slurry is pumped into the second branch pipe on the slab beam, and the concrete slurry flows into the channel steel through the first branch pipe, filling the two opposite channel steels. After the concrete slurry solidifies, the side frame and the slab beam are fixed together, which is convenient and quick. Since the pipe gallery is divided into side frames and slab beams, the individual volume and weight of the side frames and slab beams are reduced, thereby reducing the space occupied by the side frames and slab beams, which is conducive to transportation and hoisting, and convenient for construction.

[0008] Optionally, the two grouting pipes in the plate beam are connected via a shunt pipe, and a pulling mechanism is provided between the side frame and the plate beam.

[0009] By adopting the above technical solution, the diverter pipe connects the two grouting pipes, and the operator only needs to pump the concrete slurry from one side to simultaneously input it into the two grouting pipes, which is conducive to improving construction efficiency.

[0010] Optionally, the pulling mechanism includes steel rods and pulling rods, the steel rods are horizontally connected to the inner top and bottom surfaces of the side frames, the steel rods in the two side frames are symmetrically distributed, the pulling rods are connected to the plate beams, and the plate beams correspond to the steel rods one by one, the steel rods are sleeved with a first steel sleeve, the first steel sleeve is provided with a plurality of limit bolts, the steel rods are provided with through grooves for the limit bolts to pass through and move, the first steel sleeve is connected to the pulling rods, and the first steel sleeve and the pulling rods are fixed by a first screw.

[0011] By adopting the above technical scheme, during lifting, the operator moves the first steel sleeve out of the side frame, and tightens the limit bolt to fix the first steel sleeve, and the first steel sleeve plays a supporting role for the slab beam; when the slab beam is in place, the operator moves the first steel sleeve again to connect it with the pull rod, and screws the first screw to fix the first steel sleeve to the pull rod, so that the side frame and the slab beam are fixed, maintaining the relative position of the side frame and the slab beam unchanged when pouring concrete slurry, which is beneficial to improve the position accuracy of the pipeline corridor after assembly.

[0012] Optionally, there are two limit bolts on each of the first steel sleeves, and one of the limit bolts is located at the end of the first steel sleeve. The second steel sleeve is hinged on the pull rod, and the side wall of the second steel sleeve is provided with a waist-shaped groove for the first screw to pass through. Vertical poles are vertically fixed in the two side frames, and a cross bar is hinged on the vertical poles. The first steel sleeve and the second steel sleeve are vertically distributed and connected to the cross bar by screws.

[0013] By adopting the above technical solution, after the side frame and the plate beam are fixed, the operator moves the first steel sleeve and the second steel sleeve downward to a vertical position and connects them to the cross bar. The first steel sleeve, the second steel sleeve and the cross bar form a hanging frame that can be used to place pipelines. This flexibly utilizes the existing structure and saves the time and resources required for the later arrangement of pipeline supports. The setting of the waist-shaped groove facilitates the connection between the first screw and the pull rod.

[0014] Optionally, the vertical rod is rotatably connected to a plurality of support plates arranged along the vertical rod's height direction, two adjacent support plates are hinged via a first connecting rod, and the cross bar is hinged to the uppermost support plate via a second connecting rod.

[0015] By adopting the above technical solution, when the crossbar rotates, each support plate is synchronously driven to rotate. Each support plate provides a supporting foundation to facilitate pipeline layout, thereby increasing the versatility of the pipeline corridor structure.

[0016] Optionally, a push plate is slidably connected in the channel steel corresponding to the plate beam, a first baffle is vertically provided on one side of the push plate, a plurality of first reinforcing ribs are vertically provided on the other side, a plurality of first through holes are provided on the first baffle, a second baffle is provided in the channel steel, the second baffle is located on the first baffle, and a plurality of second through holes are provided on the second baffle, the second through holes are staggered with the first through holes, a plurality of third through holes are provided on the push plate, the height of the third through holes is lower than the first baffle, and the first branch pipe is higher than the first baffle.

[0017] By adopting the above technical solution, when concrete slurry enters the channel steel, the push plate moves forward under the thrust of the slurry, so that the first reinforcing rib enters the opposite channel steel; when the first through hole coincides with the second through hole, the slurry enters the area below the first baffle plate, and then enters the opposite channel steel through the third through hole. After the slurry solidifies, the first reinforcing rib crosses the two channel steels, thereby increasing the connection strength and shear resistance between the side frame and the plate beam; when the upper end of the push plate is initially impacted by the concrete slurry, the first baffle plate is blocked by the second baffle plate, thereby limiting the skewness of the push plate and increasing the stability of the push plate movement.

[0018] Optionally, a positioning block is provided in the channel steel corresponding to the plate beam.

[0019] By adopting the above technical solution, when the push plate abuts against the positioning block, the first through hole and the second through hole overlap, which plays a role in positioning the push plate.

[0020] Optionally, the channel steel corresponding to the side frame is provided with second reinforcing ribs which are staggered with the first reinforcing ribs.

[0021] By adopting the above technical solution, the second reinforcing rib further increases the connection strength between the side frame and the plate beam.

[0022] Optionally, a slurry outlet hole is opened at the bottom of the channel steel, and the side wall of the push plate is connected to a baffle frame through a support rod, and the outer contour of the baffle frame is matched with the inner contour of the channel steel.

[0023] By adopting the above technical solution, the push plate drives the baffle frame forward to cover the joint between the two channel steels, thereby reducing the possibility of slurry seepage.

[0024] Optionally, the outer wall of the baffle frame is provided with a first flow channel and two second flow channels parallel to each other, the first flow channel is connected with the two second flow channels and passes out of the baffle frame toward the push plate, the second flow channel is distributed along the outer contour of the baffle frame and the second flow channel cross-section is T-shaped, and the inner wall of the channel steel is provided with a T-shaped flow channel corresponding to the second flow channel.

[0025] By adopting the above technical solution, the slurry flows into the second flow channel and the T-shaped flow channel along the first flow channel. After the slurry solidifies, an H-shaped structure is formed, which fastens the retaining frame and the two channel steels together, thereby strengthening the connection between the side frame and the plate beam.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Since the pipe gallery is divided into side frames and plate beams, the individual volumes of the side frames and plate beams are reduced, which reduces the space occupied by the side frames and plate beams, facilitates transportation, hoisting and construction;

[0028] 2. The first steel sleeve, the second steel sleeve and the cross bar form a hanging frame that can be used to place pipelines, flexibly utilizing the existing structure and saving time and resources required for the later arrangement of pipeline supports. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is combined with Figure 1-6 This application is described in further detail.

[0037] The present application embodiment discloses a prefabricated pipe gallery. Figure 1 The prefabricated pipe gallery includes two side frames 1 and two plate beams 2. The two side frames 1 are U-shaped and their openings are opposite to each other. The two plate beams 2 are horizontally located between the two side frames 1, and one of the plate beams 2 corresponds to the top end of the side frame 1, and the other plate beam 2 corresponds to the bottom end of the side frame 1. A sink groove 3 is provided on one side where the end of the side frame 1 and the plate beam 2 are connected to each other. A channel steel 31 is fixed in the sink groove 3, and the notch of the channel steel 31 faces outward.

[0038] like Figure 2 , Figure 3 and Figure 4 A grouting pipe 32 and a diverter pipe 33 are pre-buried in the plate beam 2. The grouting pipe 32 corresponds to the channel steel 31 one by one. The grouting pipe 32 is located on one side close to the bottom of the channel steel 31 and is parallel to the channel steel 31. The grouting pipe 32 is connected to the channel steel 31 through a plurality of first branch pipes 321. Both ends of the grouting pipe 32 are vertically connected to a second branch pipe 322, and the second branch pipe 322 passes upward out of the side frame 1. The diverter pipe 33 is vertically located between the two grouting pipes 32, and both ends of the diverter pipe 33 are respectively connected to the two grouting pipes 32.

[0039] like Figure 2 A push plate 5 is slidably connected in the channel steel 31 corresponding to the plate beam 2, and the push plate 5 is fitted with the inner wall of the channel steel 31. A first baffle 51 is vertically provided on the side of the push plate 5 away from the notch of the channel steel 31, and a plurality of first reinforcing ribs 52 are vertically provided on the side of the push plate 5 facing the notch of the channel steel 31 and are equidistantly arranged along its length direction. A plurality of third through holes 54 are provided on the side wall of the push plate 5, and the height of the third through holes 54 is smaller than the first baffle 51. The connection point of the first branch pipe 321 and the channel steel 31 is higher than the first baffle 51, and a positioning block 55 is provided on the inner bottom surface of the channel steel 31 on the side of the push plate 5 facing the notch.

[0040] like Figure 2 and Figure 3 The push plate 5 is connected to a baffle frame 62 through a support rod 61 on one side facing the notch of the channel steel 31. The outer contour of the baffle frame 62 is adapted to the inner contour of the channel steel 31. The outer wall of the baffle frame 62 is provided with a first flow channel 621 and two second flow channels 622 parallel to each other. The first flow channel 621 runs through the two second flow channels 622 and passes out of the baffle frame 62. The second flow channel 622 is distributed along the outer contour of the baffle frame 62 and the cross-section of the second flow channel 622 is T-shaped. The inner wall of each channel steel 31 is provided with a T-shaped flow channel 63 extending along its own inner contour at one end close to its notch.

[0041] A second baffle plate 53 is provided at the bottom of the channel steel 31, and the second baffle plate 53 is attached to the first baffle plate 51 and the two are parallel to each other. The first baffle plate 51 is provided with a plurality of first through holes 511 distributed along its length direction, and the second baffle plate 53 is provided with second through holes 531 corresponding to the first through holes 511 one by one. The first baffle plate 51 and the second baffle plate 53 divide the area between the bottom of the channel steel 31 and the push plate 5 into two upper and lower parts; when the second baffle plate 53 abuts against the push plate 5, the first through hole 511 and the second through hole 531 are misaligned, and when the push plate 5 abuts against the positioning block 55, the first through hole 511 and the second through hole 531 coincide with each other, and the first reinforcing rib 52 is partially inserted into the adjacent channel steel 31, and the baffle frame 62 is located at the joint of the two opposite channel steels 31, and the T-shaped flow channel 63 corresponds to the second flow channel 622 one by one.

[0042] The channel steel 31 corresponding to the side frame 1 is provided with second reinforcing ribs 56 staggered with the first reinforcing ribs 52. A plurality of slurry outlet holes 6 are provided at the bottom of each channel steel 31, and the position of the slurry outlet holes 6 is lower than the second baffle 53.

[0043] During assembly, the side frame 1 and the plate beam 2 are put in place by hoisting, and the butt joint of the side frame 1 and the plate beam 2 is pumped into one of the second branch pipes 322 on the plate beam 2. The slurry is transported to the grouting pipe 32 along the second branch pipe 322, and then flows into the channel steel 31 through each first branch pipe 321. At the same time, the slurry in the grouting pipe 32 is input into another grouting pipe 32 through the shunt pipe 33. Since the interior of the channel steel 31 is separated by the first baffle plate 51 and the second baffle plate 53, the push plate 5 moves forward and approaches the side frame 1 under the pressure of the slurry, and the push plate 5 drives the first reinforcing rib 52 and the baffle frame 62 to move synchronously until the push plate 5 abuts against the positioning block 55, and the first reinforcing rib 52 and the second reinforcing rib 56 are abutted. Staggered insertion, the baffle frame 62 moves to the docking position of the two channel steels 31 to cover the docking gap between the two channel steels 31; the first through hole 511 coincides with the second through hole 531, and the slurry above the first baffle 51 flows into the area below the first baffle 51 through the first through hole 511 and the second through hole 531. At this time, part of the slurry flows into the gap between the trough 3 and the channel steel 31 from the slurry outlet hole 6, and the other part flows into the two channel steels 31 from the third through hole 54, and is injected from the slurry outlet hole 6 of the opposite channel steel 31; the slurry in the channel steel 31 is transported from the first flow channel 621 to the second flow channel 622 and the T-shaped flow channel 63; when the remaining second branch pipes 322 overflow with slurry, the grouting is stopped, and the second branch pipes 322 are sealed with a slurry stopper.

[0044] After the concrete slurry solidifies, the side frame 1 and the plate beam 2 are fixed together. The first reinforcing rib 52 and the second reinforcing rib 56 in the channel steel 31 play a role in increasing the strength of the concrete block, so that the shear resistance between the side frame 1 and the plate beam 2 is improved. At the same time, the H-shaped concrete block formed between the retaining frame 62 and the channel steel 31 pulls the retaining frame 62 and the two channel steels 31 together, which on the one hand strengthens the connection between the side frame 1 and the plate beam 2, and on the other hand, it also separates the joints of the two channel steels 31, which has an anti-seepage effect. During construction, the channel steels 31 at two locations of the plate beam 2 can be grouted together through the shunt pipe 33, saving the time required for grouting one by one and improving the construction efficiency. In addition, the operator can arrange waterproof strips on the end face where the notch of the channel steel 31 is located to strengthen the sealing of the joint between the two channel steels 31.

[0045] like Figure 2 and Figure 5 A tension mechanism 4 is provided between the side frame 1 and the plate beam 2, and the tension mechanism 4 includes a steel rod 41 and a tie rod 42. A plurality of steel rods 41 are provided and are respectively fixed on the inner top surface and the inner bottom surface of the side frame 1, and each steel rod 41 is horizontally distributed and perpendicular to the channel steel 31. The steel rods 41 on the inner top surface and the inner bottom surface of each side frame 1 correspond one to one, and the steel rods 41 in the two side frames 1 are symmetrically distributed, and there is a tie rod 42 between each group of steel rods 41, and each tie rod 42 is respectively fixed on the opposite side of the two plate beams 2.

[0046] A first steel sleeve 43 is sleeved on the steel rod 41. The cross-section of the first steel sleeve 43 is U-shaped and can move along the steel rod 41. Two limit bolts 431 are vertically passed through the first steel sleeve 43. The heads of the limit bolts 431 abut against the steel rod 41. One of the limit bolts 431 is located at the end of the first steel sleeve 43 away from the pull rod 42, and the other limit bolt 431 is close to the middle of the first steel sleeve 43. A through groove 411 for the limit bolt 431 to pass through is opened on the steel rod 41. The through groove 411 is distributed along the length direction of the steel rod 41, so that the limit bolt 431 can move along the through groove 411. The first steel sleeve 43 is plugged into the pull rod 42, and the first steel sleeve 43 is fixed to the pull rod 42 by a first screw 44.

[0047] During construction, the bottom layer of slab beam 2 is first laid and positioned, and then the side frames 1 on both sides are put in place, the first steel sleeve 43 under the moving side frame 1 is plugged into the tie rod 42 and fixed with the first screw 44, the limiting bolt 431 is tightened to pre-fix the side frame 1 and the slab beam 2, and then the first steel sleeve 43 above the side frame 1 is moved out of the side frame 1, and the limiting bolt 431 is tightened to fix the first steel sleeve 43; the upper slab beam 2 is hoisted, and the slab beam 2 is hoisted on the first steel sleeve 43 above the two side frames 1 and the tie rod 42 is plugged into the corresponding first steel sleeve 43, which, on the one hand, plays a role in positioning the slab beam 2, and on the other hand, facilitates the subsequent casting operation of the slab beam 2 and the side frame 1 through temporary support of the slab beam 2.

[0048] like Figure 5 and Figure 6 , a second steel sleeve 45 is hinged on the pull rod 42, the cross section of the second steel sleeve 45 is C-shaped and plugged with the pull rod 42 on the outside of the pull rod 42, and a waist-shaped groove 451 is provided on the side wall of the second steel sleeve 45 for the first screw 44 to pass through. Vertical poles 46 are fixed vertically in both side frames 1, and the vertical poles 46 are located between two steel rods 41 opposite to each other in the side frame 1, and each vertical pole 46 is rotatably connected with a cross bar 47 and a plurality of support plates 48, and the cross bar 47 is located above the support plate 48, and a second connecting rod 482 is hinged on the cross bar 47, and one end of the second connecting rod 482 away from the cross bar 47 is hinged to the side wall of the support plate 48 located at the top, and a first connecting rod 481 is provided between two adjacent support plates 48, and the two ends of the first connecting rod 481 are respectively hinged to the two support plates 48 opposite to it. The first steel sleeve 43 and the second steel sleeve 45 located above are both distributed vertically and the lower ends of the first steel sleeve 43 and the second steel sleeve 45 are connected to the cross bar 47 by screws. At this time, the cross bar 47 and each support plate 48 are in a horizontal position. The first steel sleeve 43, the second steel sleeve 45 and the cross bar 47 constitute a hanging frame structure, which can be used for supporting and laying pipelines. At the same time, the support plates 48 in each side frame 1 also form a supporting and laying structure for the pipeline in the vertical space, which makes full use of the existing structure, has high flexibility and occupies little space.

[0049] The implementation principle of the embodiment of the present application is: during construction, first hoist and position the bottom layer of slab beam 2, then hoist the side frames 1 on both sides of the slab beam 2 to correspond to it, move the first steel sleeve 43 under the slab beam 2, so that the first steel sleeve 43 is inserted into the second steel sleeve 45, and the first screw 44 is passed through the waist groove 451 to fix it to the pull rod 42, and then the limiting bolt 431 is tightened to fix the first steel sleeve 43 to the steel rod 41, so as to pre-fix the lower end of the side frame 1 to the bottom layer of slab beam 2.

[0050] Move the first steel sleeve 43 corresponding to the upper end of the side frame 1 to slide out of the side frame 1, use each first steel sleeve 43 as a support, hang the upper plate beam 2 on the first steel sleeve 43, and insert the second steel sleeve 45 into the first steel sleeve 43, adjust the position of the first steel sleeve 43, and fix the upper end of the side frame 1 to the upper plate beam 2 by the limiting bolt 431 and the first screw 44.

[0051] Concrete slurry is poured into the connection point between the side frame 1 and the plate beam 2 by pumping. Each plate beam 2 can be grouted on one side. At the same time, the joints between the pipe galleries are sealed with anti-seepage concrete. After the concrete solidifies, the first screw 44 corresponding to the upper plate beam 2 and the limiting bolt 431 in the middle of the first steel sleeve 43 corresponding to the upper end of the side frame 1 are removed, the first steel sleeve 43 and the second steel sleeve 45 are moved to a downward vertical position, the limiting bolt 431 is tightened to fix the first steel sleeve 43, and the cross bar 47 is rotated upward to a horizontal position so that the cross bar 47 is plugged with the lower ends of the first steel sleeve 43 and the second steel sleeve 45, and the cross bar 47 is fixed to the first steel sleeve 43 and the second steel sleeve 45 by screws. The first steel sleeve 43, the second steel sleeve 45 and the cross bar 47 constitute a hanging frame structure, and each support plate 48 rotates to a horizontal state following the cross bar 47, together forming the structural foundation for the vertical laying of the pipeline.

[0052] The tunnel is divided into side frame 1 and plate beam 2. Compared with the overall volume of the tunnel, the weight and space occupied by the individual components of the side frame 1 and plate beam 2 are reduced, which is convenient for transportation and assembly. This reduces the need for large molds during tunnel production and large vehicles during construction, and provides convenience for on-site construction.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
