Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to the technical field of small and medium-sized ditch wall concrete pouring construction, and more particularly to a bidirectional pouring method for ditch wall concrete. Background Art

[0002] Drainage ditches are slender structures with narrow hollow zones. During ditch construction, pouring concrete into the ditch walls can lead to uncontrolled concrete fall, resulting in large scattering and uncontrolled placement. This leads to material waste and increased construction costs. Therefore, it is crucial to develop a construction method that is simple, easy to operate, and low in cost. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a bidirectional pouring method for ditch wall concrete, which uses a bidirectional diversion device to constrain the concrete inside the bidirectional diversion device and flow in the constrained direction, and pour the concrete to the designated position, which can reduce material waste and shorten operation time.

[0004] To achieve this technical purpose, the present invention adopts the following scheme: A bidirectional pouring method for ditch wall concrete comprises the following steps: S1. Tie steel bars and set up and reinforce the formwork of the ditch wall according to the design requirements; S2, making a two-way flow guide device; The two-way guide device includes a bottom plate, which is composed of a first bottom plate and a second bottom plate. The first bottom plate and the second bottom plate are connected at the top and are arranged at an angle between the first bottom plate and the second bottom plate. A support is provided between the first bottom plate and the second bottom plate, and constraint baffles are provided on both sides of the bottom plate. A roller is provided at the bottom of the bottom plate, and positioning blocks are installed at the bottom of the bottom plate and the outside of the template. S3. Install the two-way guide device above the ditch and adjust the positioning block to ensure the concrete flow direction; S4. Adjust the roller to ensure that the two-way guide device can move freely forward and backward; S5. Continuously pour concrete.

[0005] Compared with the prior art, the present invention has the following beneficial effects: The method of the present invention utilizes a self-made two-way flow guide device to confine concrete within the device. As concrete is continuously conveyed, it is constrained by the two-way flow guide device, flowing in the direction of the constraint and being poured into the designated location. This method not only saves material costs, but also significantly reduces the time required to pour concrete and reduces worker workload. It is an economical, simple, convenient, and flexible method for concrete placement, with promising prospects for widespread adoption.

[0006] Furthermore, the width of the bottom plate is consistent with the inner width of the ditch, and the length of the bottom plate is 1.2m~1.5m.

[0007] Furthermore, the two-way flow guide device is also provided with a splash baffle, which is connected to the restraining baffle.

[0008] Furthermore, a pump tube fixing structure is installed on the two-way guide device. The pump tube fixing structure includes a circular ring and a fixing bracket.

[0012] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific embodiments, but the present invention is not limited thereto.

[0013] See also Figures 1 to 4 The present invention provides a bidirectional pouring method for ditch wall concrete, comprising the following steps: S1. Tie the steel bars according to the design requirements, set up and reinforce the formwork 2 of the ditch wall 1, and prepare the conditions for pouring concrete; S2, making a two-way flow guide device; The two-way diversion device includes a base plate 3, which consists of a first base plate 31 and a second base plate 32. The first and second base plates 31 and 32 are connected at their tops and arranged at an angle. The angle is preferably 90°, but can be adjusted based on actual conditions. The angle between the first and second base plates 31 and 32 and the ground is preferably 45°, which can be adjusted based on actual use. The base plate 3 is made of a smooth material, such as plywood, to ensure smooth concrete flow. The width of the base plate 3 (i.e., the distance between the bottom edges of the first and second base plates 31 and 32) matches the internal width of the gutter. The base plate 3 is 1.2 to 1.5 meters long and is reinforced according to its length. A support 4 is provided between the first and second base plates 31 and 32 to fix the top angle of the base plate 3 and prevent deformation.

[0014] Constraint baffles 5 are provided on both sides of the bottom plate 3 , and the height of the constraint baffles 5 is determined according to the speed of pouring concrete.

[0015] In some embodiments, the two-way guide device is further provided with a splash shield 6, which is connected to the constraint shield 5. The width of the splash shield 6 is preferably 400 mm, and the distance from the top of the constraint shield 5 is preferably 400 mm.

[0016] The splash guard plate 6 is installed according to actual use conditions. If artificial casting is adopted, the splash guard plate 6 can be cancelled.

[0017] In one embodiment, a pump pipe fixing structure 7 is mounted on the two-way flow guide device. The pump pipe fixing structure 7 includes a circular ring 71 and a fixing bracket 72. The two sides of the circular ring 71 are connected to the fixing bracket 72, and the fixing bracket 72 is connected to the restraining baffle 5. The diameter of the circular ring 71 should be slightly larger than the diameter of the pump pipe (50 mm), preferably 60 mm to 100 mm, to avoid insufficient restraint on the pump pipe due to the excessive diameter of the circular ring 71, which would hinder concrete pouring.

[0018] Whether the pump pipe fixing structure 7 is installed is determined according to actual usage. If manual concrete pouring is used, this structure may not be installed.

[0019] In some embodiments, rollers 8 are provided at the bottom of the bottom plate 3 to facilitate the movement of the two-way guide device. The positions of the rollers 8 are determined according to actual conditions and can be provided at both ends of the bottom plate 3 .

[0020] In some embodiments, a brake is further provided at the bottom of the bottom plate 3 for stopping the moving two-way air flow guide device.

[0021] In some embodiments, positioning blocks 9 are installed at the bottom of the base plate 3 and the outside of the template 2, leaving a 5mm gap with the inner template to prevent the two-way guide device from moving left and right, ensuring that the concrete flows into the water ditch.

[0022] S3. Install the two-way guide device above the ditch and adjust the positioning block 9 to ensure the concrete flow direction.

[0023] S4. Adjust the roller 8 to ensure that the two-way guide device can move freely forward and backward, and check the brake; S5. Continuously pour concrete.

[0024] The method of the present invention utilizes a self-made two-way flow guide device to confine concrete within the device. As concrete is continuously conveyed, it is constrained by the two-way flow guide device, flowing in the direction of the constraint and being poured into the designated location. This method not only saves material costs, but also significantly reduces the time required to pour concrete and reduces worker workload. It is an economical, simple, convenient, and flexible method for concrete placement, with promising prospects for widespread adoption.

[0025] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art may make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered to be within the scope of protection of the present invention.
