Description

Technical Field

[0001] This utility model relates to a material distribution device for concrete pouring in drainage ditches of highway engineering. Background Technology

[0002] In highway construction, drainage ditches are crucial facilities for ensuring highway drainage and preventing roadbed damage from water. The quality of their concrete pouring directly affects the service life and traffic safety of the highway. Currently, the concrete pouring of drainage ditches in highway engineering mainly adopts traditional construction methods. These methods have many technical drawbacks and cannot meet the demands for efficient and high-quality construction. Specific problems are as follows:

[0003] Traditional concrete pouring relies heavily on manual labor combined with ordinary single-outlet hoppers: a crane or forklift first lifts the hopper to the top of the pit, then the hopper's outlet is manually controlled to pour concrete into multiple pouring chambers within the pit one by one. Because ordinary hoppers have only one outlet, simultaneous pouring into multiple chambers is impossible. For construction scenarios with long sections (typically ≥50m in length for a single drainage ditch) requiring multiple pouring chambers, the hopper position must be repeatedly adjusted, and pouring a single drainage ditch section typically takes over 8 hours, resulting in extremely low construction efficiency. This method is particularly problematic in tight-schedule highway projects, easily leading to overall project delays and increased costs.

[0004] Based on the above problems, we designed a material distribution device for pouring concrete for drainage ditches in highway engineering that can achieve simultaneous and continuous pouring on both sides. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a material distribution device for pouring concrete for drainage ditches in highway engineering that can achieve simultaneous and continuous pouring on both sides.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A material distribution device for concrete pouring in drainage ditches of highway engineering, comprising,

[0008] The support unit connects to the forklift's fork arm. The support unit moves forward or backward with the forklift and its height is adjusted in sync with the forklift's fork arm.

[0009] The material distribution device, which is fixedly installed by the support device, has two discharge ends to simultaneously pour concrete into two pouring chambers within the foundation pit.

[0010] A feeding device is fixedly installed via the bracket device, and the feeding device feeds material toward the center of the distributing device.

[0011] Preferably, the support device includes an L-shaped support rod and two inserts fixedly disposed at the bottom of the support rod for inserting into the fork arm of a forklift. The material distribution device is installed on the side of the support rod, and the feeding device is installed on the top of the support rod.

[0012] Preferably, a locking screw for fixing the forklift fork arm is screwed into the bottom of the socket.

[0013] Preferably, the material distribution device includes a material pipe, a shaft, a drive motor, and discharge ports. The material pipe is arranged horizontally and fixed by the support rod. The shaft is rotatably installed inside the material pipe via a bearing. A shaft seal is installed on the inner side of the bearing to prevent grout leakage. The drive motor is connected to one end of the material pipe via a flange and drives the shaft. A connecting pipe is provided at the middle of the top of the material pipe, which cooperates with the feeding device. Two spiral blades with opposite rotation directions are provided on the shaft. There are two discharge ports, located at both ends of the bottom of the material pipe. When the shaft rotates clockwise, the two spiral blades convey in opposite directions to transport the concrete fed from the connecting pipe to the discharge ports at both ends.

[0014] Preferably, two reinforcing rods are fixedly installed on the outer wall of the material tube, the two reinforcing rods are parallel, and the support rod is fixed to the reinforcing rods.

[0015] Preferably, a conical polymer cup is provided on the inner wall of the connecting pipe, and the diameter of the polymer cup gradually decreases downward.

[0016] Preferably, the feeding device includes a feeding pipe, a feeding hopper, a second shaft, and a second drive motor. The second shaft is rotatably mounted inside the feeding pipe via a bearing, and the inner side of the bearing is sealed by a shaft seal. The feeding pipe is fixed to the top of the support rod. The second drive motor is fixed to the left end of the feeding pipe via a flange. The right end of the feeding pipe is curved downwards and then connected to the connecting pipe. A second spiral blade is fixed on the second shaft. The feeding hopper is located at the top of the feeding pipe near the second drive motor.

[0017] The beneficial effects of this utility model are:

[0018] Firstly, this device employs a material distribution system with two discharge ends, coupled with a reverse spiral blade structure, enabling simultaneous delivery of concrete to two pouring cavities within the foundation pit. Compared to the traditional single-cavity sequential pouring method, this more than doubles the construction efficiency. Taking a 50m long drainage ditch with 800mm spacing between two pouring cavities as an example, this method can complete the pouring in just 3-4 hours, saving over 50% of the time compared to traditional methods and effectively shortening the project duration.

[0019] Secondly, the automatic conveying of concrete is achieved by driving the spiral blades with a motor, eliminating the need for manual control of the discharge speed. The position of the feeding hopper is adapted to the feeding height of the loader, allowing the loader to feed directly and continuously, reducing the manual transfer process. The number of workers required for a single drainage ditch construction section can be reduced from the traditional 8-10 people to 3-4 people, reducing labor costs while avoiding the efficiency fluctuations of manual operation.

[0029] See Figure 1 The illustrated material distribution equipment for concrete pouring in drainage ditches of highway engineering includes,

[0030] The support device 1 is connected to the forklift's fork arm. The support device 1 moves forward or backward with the forklift and its height is adjusted along with the fork arm.

[0031] The material distribution device 2 is fixedly installed via the support device 1. The material distribution device 2 has two discharge ends to simultaneously pour concrete into two pouring chambers within the foundation pit.

[0032] The feeding device 3 is fixedly installed by the bracket device 1, and feeds material to the middle of the distributing device 2.

[0033] This device is driven by a forklift, which carries a battery to power the device.

[0034] Before pouring the concrete, two template sets need to be installed in the foundation pit of the drainage ditch. Each template set consists of two parallel templates, and the inner side of the template set is the pouring cavity.

[0035] The device is carried to the top of the drainage ditch pit by a forklift, and the two discharge ends of the material distribution device 2 are respectively aligned with the two pouring cavities on both sides.

[0036] Then, concrete is put into the feeding device 3 by means of a loader or manual labor. The feeding device 3 feeds the concrete towards the middle of the distribution device 2, and then the distribution device 2 distributes the concrete to both sides to complete the concrete pouring work of the two pouring chambers at the same time.

[0037] This device moves with the forklift to complete the mobile pouring process.

[0038] See Figure 1As shown, the support device 1 includes an L-shaped support rod 11 and a plug sleeve 12 fixedly disposed at the bottom of the support rod 11. Two plug sleeves 12 are provided for inserting into the fork arm of the forklift. The material distribution device 2 is installed on the side of the support rod 11, and the feeding device 3 is installed on the top of the support rod 11.

[0039] A locking screw 13 for fixing the forklift fork arm is screwed into the bottom of the sleeve 12.

[0040] The forklift's fork arm is inserted through the insert 12, then the fork arm is lifted, and the locking screw 13 is tightened to fix the insert 12 to the forklift's fork arm.

[0041] See Figure 1 and Figure 2 As shown, the material distribution device 2 includes a material pipe 21, a shaft 22, a drive motor 23, and a discharge port 24. The material pipe 21 is arranged horizontally and is fixed by the support rod 11. The shaft 22 is rotatably mounted inside the material pipe 21 via a bearing. A shaft seal is installed on the inner side of the bearing to prevent slurry leakage. The drive motor 23 is connected to one end of the material pipe 21 via a flange and drives the shaft 22. The drive motor 23 is powered by a battery carried on a forklift, or it can be powered by a field power supply with a long-distance power cable (the power cable is a coiled cable for long-distance delivery). The drive motor 23 is equipped with a dedicated motor controller to adjust the output speed of the drive motor 23. The drive motor 23 is a geared motor with a reduction ratio of 1:10. A connecting pipe 25 is provided at the top middle position of the material pipe 21. The feeding device 3 is connected through the connecting pipe 25. Two spiral blades 26 with opposite rotation directions are provided on the shaft 22. There are two discharge ports 24, which are fixed to the two ends of the bottom of the material pipe 21 by screws. When the shaft 22 rotates clockwise, the two spiral blades 26 convey in opposite directions to transport the concrete fed from the connecting pipe 25 to the discharge ports 24 at both ends.

[0042] In the above technical solution, a drive motor is used to drive the shaft 22 to rotate, so that the two spiral blades 26 rotate synchronously to achieve material distribution, and send the two portions of concrete into the pouring cavities on both sides.

[0043] Furthermore, during the concrete pouring process, the forklift should be kept moving slowly at 1-5 m / min to achieve mobile pouring.

[0044] The forklift speed is controlled at 1-5 m / min, and a designated person directs the forklift's movement via walkie-talkie; the concrete feeding speed is matched with the speed of the second drive motor 34, and the feeding amount per hour is controlled at 6-8 m³, to avoid the concrete accumulating in the feeding hopper 32 to more than 2 / 3 of its volume.

[0045] See Figure 1 As shown, two reinforcing rods 221 are fixedly installed on the outer wall of the material tube 21. The two reinforcing rods 221 are parallel, and the support rod 11 is fixed to the reinforcing rods 221.

[0046] The reinforcing rod 221 is designed to increase the bending strength of the material tube 21. At the same time, the reinforcing rod 221 is connected to the support rod 11 to reduce the deformation of the material tube 21.

[0047] See Figure 2 As shown, a conical polymer cup 251 is welded to the inner wall of the connecting pipe 25, and the diameter of the polymer cup 251 gradually decreases downward.

[0048] The feed cup 251 is designed to center the feed, so that the amount of concrete conveyed by the spiral blades 26 on both sides is as uniform as possible.

[0049] After pouring, immediately add 50L of clean water to the feeding hopper 32, start the two motors and flush for 10 minutes. During the flushing process, repeatedly reverse the motors (30 seconds each time) to ensure that there is no concrete residue in the material pipe 21 and the feeding pipe 31. After flushing, disconnect the power, remove the motor power cord, and hoist the equipment to the dry storage area.

[0050] See Figure 1 and Figure 3 As shown, the feeding device 3 includes a feeding pipe 31, a feeding hopper 32, a second shaft 33, and a second drive motor 34. The second shaft 33 is rotatably mounted inside the feeding pipe 31 via a bearing, and the inner side of the bearing is sealed by a shaft seal. The feeding pipe 31 is fixed to the top of the support rod 11. The second drive motor 34 is fixed to the left end of the feeding pipe 31 via a flange. The second drive motor 34 is also a geared motor, and its power supply method is the same as that of the drive motor. It also uses a motor controller to set the speed separately. The reduction ratio of the second drive motor 34 is 1:8. The right end of the feeding pipe 31 is curved downward and then connected to the connecting pipe 25. A second spiral blade 35 is fixed on the second shaft 33. The feeding hopper 32 is located at the top of the feeding pipe 31 near the second drive motor.

[0051] In the above technical solution, the feeding hopper 32 is located close to the second drive motor so that the feeding position is located on the side of the drainage ditch, above the ground, which facilitates the feeding of concrete.

[0052] (a) Inspection and debugging of material distribution equipment

[0053] Component integrity check: Referring to Figure 1 (overall structural schematic diagram of the material distribution equipment) and Figure 2 (enlarged view of the support device), confirm that the L-shaped support rod 11 and the sleeve 12 of the support device 1 are not deformed, and that the locking screw 13 (M16×50mm 8.8 grade high strength screw) is not corroded; check whether the material pipe 21 (stainless steel material, inner diameter 200mm), shaft 22 and two reverse spiral blades 26 (pitch 150mm) of the material distribution device 2 are intact, and whether the feeding hopper 32 and the feeding pipe 31 (inner diameter 180mm) of the feeding device 3 are crack-free.

[0054] Power supply system debugging: If the forklift carries a battery for power supply, the motor controller needs to be connected through a waterproof junction box to test the rotation direction of the drive motor 23 (3kW geared motor, reduction ratio 1:10) and the second drive motor 34 (2.2kW geared motor, reduction ratio 1:8): Start the second drive motor 34 and observe whether the second spiral blade 35 feeds to the right end of the feed pipe 31 (to match the feeding requirements of the connecting pipe 25); Start the drive motor 23 and confirm that when the shaft 22 rotates clockwise, the two spiral blades 26 feed to both ends of the feed pipe 21 (to match the two discharge ports 24). If the rotation direction is reversed, adjust the power line phase.

[0055] No-load test run: Start both motors simultaneously and run for 5 minutes. Check that there is no abnormal vibration in the material pipe 21 and the feeding pipe 31, and that the motor temperature rise is ≤60℃. Move the forklift and test the stability of the material distribution equipment as it moves with the forklift to ensure that the insert 12 fits tightly with the forklift fork arm without shaking.

[0056] (II) Preparation of foundation pit and formwork

[0057] Foundation pit cleaning: Clean up the gravel, weeds and water in the foundation pit of the drainage ditch. If there is a loose soil layer at the bottom of the foundation pit, a 100mm thick layer of graded sand and gravel should be laid and compacted (compaction degree ≥95%) to ensure that the foundation is flat and solid.

[0058] Template assembly: Two template assemblies are assembled using 6mm thick steel templates. Each template assembly consists of two parallel steel templates (1.2m high, consistent with the design height of the pouring cavity). The length is adjusted according to actual needs, and adjacent templates are assembled. Release agent is applied to the inside of the templates. The spacing between the template assemblies is adjusted to 800mm (consistent with the center distance between the two discharge ports 24 of the material distribution device 2, with a deviation ≤5mm). They are fixed with M12 tie bolts (bolt spacing 500mm). φ48mm steel pipe supports are installed on the outside (support angle 60°, one every 1.5m). The verticality of the templates is checked with a level (deviation ≤0.5°) to prevent template displacement during pouring.

[0059] (III) Concrete Preparation

[0060] Concrete is prepared according to the design strength of the drainage ditch (usually C30 concrete) and the mix ratio (cement:sand:aggregate:water = 1:1.8:3.5:0.5). The slump is controlled at 120-160mm (using a slump cone tester, the concrete drop time should be 3-5 seconds during the test). If construction is carried out in a high-temperature (≥30℃) environment, water should be sprayed into the aggregate to cool it down and avoid shortening the initial setting time of the concrete (the initial setting time should be ≥2h to meet the requirements of the pouring operation).

[0061] II. Pouring Operation Stage

[0062] (a) The material distribution equipment is in place.

[0063] Fork arm connection and fixing: Drive a forklift (5-ton recommended), align the fork arm with the two inserts 12 of the bracket device 1, slowly insert it until the insert depth is ≥250mm, raise the fork arm so that the material distribution device is 300mm off the ground, tighten the locking screw 13 to ensure that the insert 12 is fixed to the fork arm.

[0064] Position calibration: Drive the forklift to lift the material distribution equipment to the top of the foundation pit, adjust the position of the forklift so that the two discharge ports 24 of the material distribution device 2 are aligned with the center of the two pouring cavities on both sides. The bottom of the discharge port is 100-150mm away from the top of the pouring cavity (to avoid concrete splashing or uneven distribution). A designated person uses a tape measure to confirm that the spacing deviation is ≤5mm.

[0065] (ii) Concrete feeding and transportation

[0066] Feeding operation: Use a loader to feed material into the feeding hopper 32. When unloading, the loader should be aligned with the center of the top opening of the feeding hopper. The feeding speed should be controlled at 6-8 m³ / h (matching the conveying capacity of the second spiral blade 35) to avoid the concrete in the feeding hopper from accumulating to more than 2 / 3 of its volume (to prevent overflow). If the concrete segregates, it needs to be manually mixed before being fed into the feeding hopper. It is strictly forbidden to mix in debris such as gravel and steel bars.

[0067] Synchronous conveying control: The speed is adjusted by the motor controller. The speed of the second drive motor 34 is set to 80-100 r / min (to ensure that the concrete enters the connecting pipe 25 at a uniform speed), and the speed of the drive motor 23 is set to 60-80 r / min (to ensure that the conveying volume of the two spiral blades 26 is uniform, with a pouring volume of 3-4 m³ per side per hour).

[0068] (iii) Mobile pouring operation

[0069] Uniform speed movement control: One person is assigned to direct the forklift movement via walkie-talkie. The forklift movement speed is set to 1m / min (in combination with the initial setting time of concrete and the pouring thickness to ensure that the pouring layer is continuous without any breaks). During the movement, avoid sudden acceleration and sudden braking to prevent the material distribution equipment from shaking and causing the discharge port to deviate.

[0070] Pouring height monitoring: Two staff members are assigned to stand on both sides of the foundation pit to measure the concrete height of the pouring cavity in real time with a ruler. When the height reaches 95% of the design height (leaving 5% for vibration settlement, the design height is usually 1.0m), the loader is notified to stop feeding. After the concrete in the feeding pipe 31 and material pipe 21 has been transported (about 1-2 minutes), the two motors are turned off.

[0071] Vibration treatment: During the concrete pouring process, a φ50mm immersion vibrator is used to vibrate the concrete in the pouring cavity. The vibrator is inserted to the bottom of the pouring layer (50mm from the bottom of the foundation pit), with a vibration interval of 300mm and a vibration time of 20-30s at each location (until no air bubbles overflow and cement slurry appears on the concrete surface). Avoid the vibrator touching the formwork (to prevent formwork displacement) or the material discharge port of the material distribution equipment (to avoid damage to components).

[0072] III. Post-pouring treatment stage

[0073] (a) Cleaning of material distribution equipment

[0074] Residual concrete washing: Hoist the material distribution equipment to the clean water pool at the construction site, add 50L of clean water into the feeding hopper 32, start the two motors (adjust the speed to 50r / min), and let the clean water circulate to wash the feeding pipe 31, material pipe 21 and discharge port 24. During this period, repeatedly reverse the motors (reverse for 30 seconds each time) until the discharged water is clear and free of concrete residue (washing time ≥10 minutes).

[0075] (II) Concrete curing and formwork removal

[0076] Curing procedures: Within 2 hours after the concrete is poured, cover its surface with geotextile (2mm thick) and use water spraying method (spray water 3-4 times a day to keep the geotextile moist) for a curing period of no less than 7 days; if the ambient temperature is below 5℃, cover the outside of the geotextile with thermal insulation cotton quilt to prevent the concrete from freezing.

[0077] Formwork Removal: 24 hours after pouring (the concrete strength must reach more than 50% of the design strength by testing with a rebound hammer), remove the formwork supports and tie bolts, and then slowly disassemble the steel formwork (avoid prying hard and causing damage to the concrete surface). After the formwork is removed, grind the rough edges of the pouring cavity (using an angle grinder, with a grinding accuracy of ≤2mm).
