Description

Technical Field

[0001] This application relates to a concrete pumping system and construction method, which is mainly applicable to concrete pumping construction in building construction. The key applications include concrete pump pipe fixing methods, concrete placing boom support methods, concrete placing hose safety protection and precise placement methods, and hopper concrete residue collection methods. Background Technology

[0002] The development of concrete pumping technology in my country began in the 1950s, starting with the initial introduction of concrete pumps, which subsequently spurred the development of concrete pump trucks. Currently, the development of concrete pump trucks continues to move towards environmental protection and energy conservation, structural optimization, lightweighting, automation, intelligence, and digitalization. The pumping unit mainly consists of a hopper, a mixing device, a long-distance pump pipe, and a placing device.

[0003] When concrete pumps deliver concrete to high-rise structures, the following problems are often encountered under the action of high-pressure pumps: 1) During the feeding process of the hopper mixing mechanism, debris such as leaves, paper scraps, and plastic film fall into the hopper, and concrete in the hopper is prone to splashing, resulting in material waste; 2) During the concrete pumping process, the pipeline generates additional unbalanced thrust, producing violent vibration, accompanied by impact and noise, which affects the safety of the main structure; 3) It is difficult to stack the placing device, the placing hose is prone to large swings, the pouring accuracy is poor, and the swinging hose is prone to injuring people.

[0004] To address the aforementioned issues, there is an urgent need for a simple and effective concrete pumping system and construction method to reduce the impact of airborne debris falling into the hopper on quality, improve the stability of concrete pump pipes in building construction, reduce vibration on floors and walls, enhance the safety and accuracy of concrete placement using the placing hose, collect and reuse concrete residue, and achieve green and environmentally friendly practices. Summary of the Invention

[0005] To achieve the above technical objectives, this application adopts the following technical solution:

[0006] A concrete pumping system includes a concrete pumping hopper, a concrete pump pipe fixing system, and a concrete pumping and pouring device.

[0007] The concrete pump hopper includes a hopper, screen, folding cover plate, mixing mechanism, concrete cylinder, discharge gate plate, primary material cylinder, secondary material cylinder, tertiary material cylinder, quaternary material cylinder, push-pull valve, discharge pipe, receiving cylinder, support, conveying cylinder, fixed crossbar, filter screen, push-pull plate, push-pull handle, strip steel plate and sliding groove.

[0008] The hopper has a screen at the top, with strip steel plates welded to both sides. A folding cover can be pushed, pulled, extended, and folded along the strip steel plates to cover the screen. A mixing mechanism is installed inside the hopper to agitate the concrete and send it to a concrete cylinder. A discharge gate is installed at the bottom of the concrete cylinder. When the discharge gate is opened, concrete residue in the hopper can be cleaned and collected through a multi-stage filtration system consisting of a primary, secondary, tertiary, and quaternary material cylinder.

[0009] The concrete pump pipe fixing system includes a hopper, mixing mechanism, conveying cylinder, steel pump pipe, steel pipe scaffolding, reinforcing locking rod, fastener, shear wall, concrete floor slab, channel steel, timber, U-shaped locking rod, concrete pier, U-shaped iron belt, expansion bolt, steel pipe, wooden wedge, rubber gasket, enclosure rod, through-wall steel cylinder, and thread.

[0010] The concrete in the hopper is transported to the steel pump pipe by the conveying cylinder under the action of the mixing mechanism. The steel pump pipe is reinforced on the ground by steel pipe scaffolding. Reinforcing locking rods and enclosure rods are installed at the horizontal to vertical corners of the ground steel pump pipe for locking. The steel pump pipe is connected to the channel steel on the floor slab by U-shaped locking rods. Concrete piers are installed at the horizontal to vertical corners of the floor slab steel pump pipe for support. Steel pipes are installed to reinforce where the steel pump pipe passes through the poured concrete floor slab. Wooden wedges are filled between the steel pump pipe and the concrete floor slab for reinforcement. Through-wall steel cylinders are installed where the steel pump pipe passes through the poured shear wall. The through-wall steel cylinders are clamped to the shear wall for fastening by fasteners.

[0011] The concrete pumping and pouring equipment includes steel pump pipes, timber, floor slab formwork, floor slab steel mesh, wooden pads, steel pads, outriggers, secondary crossarms, primary crossarms, rotating handles, chassis, uprights, main beam frame, vertical trusses, hinges, hydraulic telescopic rods, rubber hoses, pipe shoes, equipment base, and shoe rings.

[0012] In this system, steel and wooden pads are placed under the legs of the pumping and pouring device. The wooden pads are placed directly on the floor slab reinforcement mesh. The secondary horizontal arm can be rotated by turning the handle to extend and retract along the inner side of the primary horizontal arm. The steel pump pipe passes through the floor slab formwork, floor slab reinforcement mesh, and base plate from bottom to top before entering the upright frame. After exiting the top of the upright frame, the steel pump pipe bends into a horizontal and downward angled state. A rubber hose is fitted onto the end of the steel pump pipe. Multiple pipe shoes are fixed at even intervals on the rubber hose. A vertical truss is set in the middle of the main beam frame. The equipment base is installed at the bottom of the vertical truss. A hydraulic telescopic rod is installed and fixed on the equipment base. The hydraulic telescopic rod is fixed to the equipment base by a hinge. The end of the hydraulic telescopic rod hooks onto the shoe ring on the pipe shoe. The extension and retraction of the hydraulic telescopic rod can control the concrete pouring position of the rubber hose.

[0013] Furthermore, the screen is made of steel bars welded into a mesh structure and placed on top of the hopper. A sliding groove is set inside the strip steel plate. The folding cover is a retractable and foldable sheet metal plate. A push-pull plate is set at the end of the folding cover, and a push-pull handle is fixed to the push-pull plate. The folding cover is embedded in the sliding groove inside the strip steel plate. Under the push-pull handle, it can extend and fold along the sliding groove to cover the screen.

[0014] Furthermore, the primary, secondary, tertiary, and quaternary material cylinders are all connected to the support via fixed crossbars. Each of the primary, secondary, and tertiary material cylinders has a filter screen at its bottom. The primary filter screen filters concrete residue with a diameter of 20mm or more; the secondary filter screen filters concrete residue with a diameter of 10mm or more; the tertiary filter screen filters concrete residue with a diameter of 5mm or more; and the quaternary filter screen directly collects concrete residue with a diameter of less than 5mm. A discharge pipe is installed at the lower right corner of the upper part of each material cylinder's filter screen. A push-pull valve is installed at the connection between the discharge pipe and the material cylinder to control the amount of material discharged. A receiving cylinder is placed at the bottom of the discharge pipe to collect concrete residue for reuse.

[0015] Furthermore, the steel pipe scaffolding is made up of multiple steel pipes tied together. The steel pump pipe is located in the middle of the scaffolding. Rubber washers are installed around the steel pump pipe. The reinforcing locking rod and the enclosing rod are combined to form an "A"-shaped structure. The steel pump pipe is reinforced at the corners by the "A"-shaped structure. Rubber washers are installed between the steel pump pipe and the "A"-shaped structure.

[0016] Furthermore, the channel steel is fixed to the concrete floor slab with expansion bolts. Wooden blocks are placed on the channel steel, and the steel pump pipe is placed on the wooden blocks. After the U-shaped locking rod presses the steel pump pipe, the bottom is connected to the channel steel with bolts. A U-shaped iron belt is installed on the concrete pier to fix the steel pump pipe, and the U-shaped iron belt is connected to the concrete pier with expansion bolts.

[0017] Furthermore, where the steel pump pipe passes through the concrete floor slab, the steel pipe needs to be installed in two layers, forming a "well" structure to reinforce the steel pump pipe. Multiple wooden wedges are evenly placed around the steel pump pipe, and the outer wall of the through-wall steel cylinder is threaded, so the fastener can be tightened by turning the thread.

[0018] Furthermore, wooden blocks are evenly arranged between the steel pad and the wooden pad. The upper part of the outrigger is welded to the secondary crossarm, and the lower part is an enlarged end structure. The connection between the secondary crossarm and the primary crossarm is an internal gear structure. When the rotating handle on the primary crossarm is turned, the extension and retraction of the secondary crossarm is controlled by the gear action, thereby moving the position of the outrigger support.

[0019] Furthermore, the chassis is square, with primary cross arms welded in all four directions. There is a circular hole in the center of the chassis, through which the steel pump pipe passes. The uprights are erected on the chassis, enclosing the steel pump pipe.

[0020] Furthermore, a shoe ring is provided on the pipe shoe, and the hydraulic telescopic rod can rotate around the hinge. An equipment base is provided at the front end of the main beam frame, and the hydraulic telescopic rod is also connected to the equipment base through a hinge. The hydraulic telescopic rods installed and fixed on the main beam frame and the vertical truss jointly control the pouring position of the rubber hose nozzle.

[0021] Secondly, a construction method for a concrete pumping system, used for constructing the aforementioned concrete pumping system, includes the following operational steps:

[0022] S00. Erecting the concrete pump hopper structure: Harden the ground according to the designed layout of the hopper, hoist the entire concrete pump hopper structure onto the hardened ground, temporarily fix the support, start the mixing mechanism to run, and check whether the equipment can work normally.

[0023] S10. Ground-fixed steel pump pipe system: After the concrete pumping hopper structure is operating correctly, connect the steel pump pipe to the conveying cylinder. The steel pump pipe is fixed on the ground by steel pipe scaffolding. Reinforcing locking rods and enclosure rods are installed at the corners for reinforcement.

[0024] S20. Steel pump pipe through wall panel: Pass the steel pump pipe through the wall through steel cylinder, insert the steel pump pipe and the wall through steel cylinder into the reserved hole in the shear wall, screw the fastener on the wall through steel cylinder, and clamp the shear wall with the fastener.

[0025] The steel pump pipe is fixed on the concrete floor slab with channel steel. Concrete blocks are used to support the pipe at the horizontal and vertical corners. Steel pipe scaffolding is set up vertically for fixation. The steel pump pipe passes through the reserved hole in the concrete floor slab. Steel pipes are set up on the top and bottom of the concrete floor slab for reinforcement. Wooden wedges are filled around the steel pump pipe in the reserved hole in the concrete floor slab.

[0026] S30. Erecting the formwork system for the floor slab to be poured: Erect formwork supports on the poured concrete floor slab, place longitudinal ribs on the formwork supports, arrange transverse ribs at even intervals on the longitudinal ribs, place the floor slab formwork on the transverse ribs, tie the floor slab steel mesh on the floor slab formwork, and reserve holes for steel pump pipes through the floor slab formwork and floor slab steel mesh.

[0027] S40. Erecting the concrete pumping and pouring device: Place wooden pads on the floor slab reinforcement mesh according to the design position, evenly place wooden blocks on the wooden pads, place steel pads on the wooden blocks, hoist the entire structure of the concrete pumping and pouring device onto the steel pads, and support the legs of the concrete pumping and pouring device on the steel pads. Check whether the elevation of the four legs of the concrete pumping and pouring device is consistent and verify whether its stability meets the construction requirements.

[0028] After passing through the reserved holes in the floor slab formwork and floor slab reinforcement mesh, the steel pump pipe enters the chassis of the concrete pumping and pouring device. Inside the chassis, the steel pump pipe inside the pumping and pouring device frame is connected to the steel pump pipe that passes through the floor slab formwork.

[0029] S50. Pouring floor slab concrete: Place a screen with a folding cover on the hopper, pour ready-mixed concrete into the hopper, and then use the push-pull handle to unfold the folding cover to cover the hopper. Start the mixing mechanism to feed the concrete into the steel pump pipe. The concrete enters the rubber hose through the steel pump pipe. Hook the end of the hydraulic telescopic rod onto the shoe ring on the rubber hose, and adjust the angle and length of the hydraulic telescopic rod to ensure precise material distribution at the outlet of the rubber hose, and pour the floor slab concrete.

[0030] S60. Displacement of pumping and pouring device: After the concrete pouring within the working range of the rubber hose is completed, a new steel pad is assembled on the side of the steel pad under the outrigger. Turn the handle to adjust the extension and retraction of the secondary cross arm so that the outrigger is moved onto the new steel pad. After checking its stability, the original steel pad and wooden pad are removed.

[0031] S70. Continue pouring floor slab concrete: Continue to use rubber hoses to pour floor slab concrete, and fill the holes left by the removal of the original steel and wooden pads with concrete.

[0032] S80. Dismantle the steel pump pipe system: After the concrete pumping work is completed, first lift the pumping and pouring device as a whole, and then dismantle the steel pump pipe and fixing device from top to bottom. The steel pump pipe and rubber hose of the pumping and pouring device are flushed with water. At the same time, the dismantled steel pump pipe, joints and elbows are flushed with water.

[0033] S90. Hopper concrete residue cleaning and collection: The hopper, screen, and folding cover are rinsed with water to clean the concrete residue. The discharge gate is opened to allow the concrete residue to fall into the multi-stage material cylinder. Concrete residue of different particle sizes is collected through the multi-stage material cylinder and discharged into the receiving cylinder for reuse through the discharge pipe.

[0034] Compared with the prior art, this application has the following features and beneficial effects:

[0035] 1) This application sets a folding cover plate on the screen at the top of the hopper. During the pumping process, the hopper is covered by the cover plate, which effectively prevents debris such as leaves, paper scraps, and plastic film from falling into the hopper and improves the quality of pumped concrete.

[0036] 2) This application sets a folding cover plate on the hopper, which effectively reduces the material waste caused by concrete splashing during the feeding process of the hopper mixing mechanism. The bottom of the hopper is equipped with a multi-stage material cylinder for graded filtration and collection of concrete residue, which reduces material waste and realizes material reuse.

[0037] 3) The ground steel pump pipe of this application is reinforced by steel pipe scaffolding. Locking rods and enclosure rods are installed at the horizontal and vertical corners for reinforcement. The floor steel pump pipe is fixed to the channel steel connected to the floor slab by U-shaped locking rods. At the corners, it is fixed to the concrete pier by U-shaped iron belts, which improves the stability of the pump pipe and reduces the impact of the pump pipe on the floor slab.

[0038] 4) When the steel pump pipe passes through the floor slab, it is reinforced with steel pipe and wooden wedges are used to protect the floor slab. When the steel pump pipe passes through the wall, it is reinforced with a through-wall steel cylinder to protect the wall. These reinforcement and protection measures avoid the impact of the pump pipe on the floor slab and wall through which it passes, and ensure the quality and safety of the main structure.

[0039] 5) This application adjusts the extension and retraction of the secondary cross arm by rotating the handle, thereby moving the outriggers and achieving the purpose of quickly adjusting the position of the fabric device.

[0040] 6) This application controls the rubber hose by installing hydraulic telescopic rods on the truss and main beam frame, which avoids the rubber hose swinging wildly and causing injury during high-pressure pumping. At the same time, the hydraulic telescopic rods precisely control the position of the rubber hose outlet, improving the accuracy and uniformity of concrete distribution. Attached Figure Description

A mixing mechanism 4 is installed inside the hopper 1, which can agitate the concrete in the hopper 1 and send it to the concrete cylinder 5. A discharge gate plate 6 is installed at the lower part of the concrete cylinder 5. After the discharge gate plate 6 is opened, the concrete residue in the hopper 1 can be cleaned and collected through a multi-stage material cylinder consisting of a primary material cylinder 7, a secondary material cylinder 8, a tertiary material cylinder 9, and a quaternary material cylinder 10. The primary material cylinder 7, the secondary material cylinder 8, the tertiary material cylinder 9, and the quaternary material cylinder 10 are all connected to the support 14 through a fixed crossbar 49.

[0069] like Figure 6 As shown, filter screens 50 are installed under the primary material cylinder 7, the secondary material cylinder 8, and the tertiary material cylinder 9. The filter screen 50 under the primary material cylinder 7 is used to filter concrete residue with a diameter of 20mm or more. The filter screen 50 under the secondary material cylinder 8 is used to filter concrete residue with a diameter of 10mm or more. The filter screen 50 under the tertiary material cylinder 9 is used to filter concrete residue with a diameter of 5mm or more.

[0070] Preferably, a discharge pipe 12 is provided at the lower right corner of the upper part of the filter screen 50, and a push-pull valve 11 is provided at the connection between the discharge pipe 12 and the material cylinder to control the discharge size of the collected material. The four-stage material cylinder 10 directly collects concrete residue with a diameter of less than 5mm, without the need to install the filter screen 50. A vertical discharge pipe 12 is provided at the bottom of the four-stage material cylinder 10, and a receiving cylinder 13 is placed at the lower part of the discharge pipe 12 to collect concrete residue for reuse.

[0071] like Figure 1 As shown, the overall structure of the concrete pumping system includes a hopper 1, a mixing mechanism 4, a conveying cylinder 15, a steel pump pipe 16, a steel pipe scaffold 17, reinforcing locking rods 18, fasteners 19, a shear wall 20, a concrete floor slab 21, channel steel 22, timber 23, a U-shaped locking rod 24, concrete piers 25, a U-shaped iron belt 26, expansion bolts 27, steel pipes 28, wooden wedges 29, rubber washers 55, enclosing rods 56, through-wall steel cylinders 57, and threads 58. The concrete in the hopper 1 is conveyed to the pumping system via the conveying cylinder 15 under the action of the mixing mechanism 4. Inside the steel pump pipe 16, the steel pump pipe 16 is reinforced on the ground by steel pipe scaffolding 17. The steel pump pipe 16 on the ground is locked with reinforcing locking rods 18 and enclosure rods 56 at the horizontal to vertical corners. The steel pump pipe 16 is connected to the channel steel 22 on the floor slab by U-shaped locking rods 24. The steel pump pipe 16 on the floor slab is supported by concrete piers 25 at the horizontal to vertical corners. The steel pump pipe 16 is reinforced by steel pipes 28 where it passes through the poured concrete floor slab 21. Wooden wedges 29 are filled between the steel pump pipe 16 and the concrete floor slab 21 for reinforcement.

[0072] like Figure 7-8 As shown, the structure for fixing the ground steel pump pipe is as follows: the steel pump pipe 16 is reinforced on the ground by a steel pipe scaffold 17. The steel pipe scaffold 17 is an integral structure made up of multiple steel pipes 28. The steel pump pipe 16 is located in the middle of the scaffold and rubber gaskets 55 are set around the steel pump pipe 16.

[0073] like Figure 9-10 As shown, the fixing structure at the corner of the ground steel pump pipe is as follows: the reinforcing locking rod 18 and the enclosing rod 56 are combined to form an "A" shape structure. The steel pump pipe 16 is reinforced at the corner by the "A" shape structure, and a rubber gasket 55 is set between the steel pump pipe 16 and the "A" shape structure.

[0074] like Figure 11-12As shown, the connection structure between the steel pump pipe and the channel steel on the floor is as follows: the channel steel 22 is fixed to the concrete floor slab 21 by expansion bolts 27, a wooden block 23 is placed on the channel steel 22, the steel pump pipe 16 is placed on the wooden block 23, and after the U-shaped locking rod 24 presses the steel pump pipe 16, the bottom is connected to the channel steel 22 by bolts.

[0075] like Figure 11 , 13 As shown, a concrete pier structure is used to support the steel pump pipe at the corner of the floor. A U-shaped iron belt 26 is installed on the concrete pier 25 to fix the steel pump pipe 16. The U-shaped iron belt 26 is connected to the concrete pier 25 by expansion bolts 27.

[0076] like Figure 14-15 As shown, the steel pump pipe is reinforced by passing through the floor slab: the steel pipe 28 needs to be set up in two layers, and the steel pipe 28 forms a "well" structure to reinforce the steel pump pipe 16; the cavity between the steel pump pipe 16 and the concrete floor slab 21 is filled with wooden wedges 29 for reinforcement, and multiple wooden wedges 29 are evenly set around the steel pump pipe 16.

[0077] like Figure 16-17 As shown, the steel pump pipe passes through the wall structure: a through-wall steel cylinder 57 is installed where the steel pump pipe 16 passes through the already poured shear wall 20. The outer wall of the through-wall steel cylinder 57 is provided with threads 58. The fastener 19 can be tightened by screwing on the threads 58. The through-wall steel cylinder 57 is clamped to the shear wall 20 by the fastener 19.

[0078] like Figure 18-19 As shown, the base support structure of the concrete pumping and pouring device includes: steel pump pipe 16, timber 23, floor slab formwork 32, floor slab reinforcement mesh 33, wooden pads 34, steel pads 35, support legs 36, secondary crossarm 37, primary crossarm 38, rotating handle 39, chassis 40, and uprights 41. The upper part of the support leg 36 is welded to the secondary crossarm 37, and the lower part is an enlarged end structure. Steel pads 35 and wooden pads 34 are placed under the support leg 36 in sequence. Timber 23 is evenly distributed between the steel pads 35 and the wooden pads 34. The wooden pads 34 are placed directly on the floor slab reinforcement mesh 33. The secondary crossarm 37 can be rotated and extended along the primary crossarm 38 by rotating the rotating handle 39. The connection between the secondary crossarm 37 and the primary crossarm 38 is an internal gear structure. When the rotating handle 39 on the primary crossarm 38 is rotated, the extension and retraction of the secondary crossarm 37 is controlled by the gear action, thereby moving the position supported by the support leg 36.

[0079] Furthermore, the chassis 40 is square, with first-level cross arms 38 welded in all four directions. The center of the chassis 40 has a circular hole, and the upright frame 41 is erected on the chassis 40.
