Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a splash prevention device and construction method for the discharge port of a pump truck. Background Technology

[0002] In existing technologies, when concrete is poured into foundations or floor slabs using a concrete pump truck, the high-speed discharge of concrete from the outlet pipe generates significant impact. If the foundation soil is not sufficiently compacted, this impact can easily damage the soil and cause it to mix with the concrete, directly affecting the quality of the concrete subbase. Alternatively, during floor slab pouring, the formwork structure is subjected to the enormous impact of the concrete pouring, posing a safety risk. There are technical problems with directly pouring concrete discharged from the outlet pipe, such as the risk of foundation damage from impact or safety hazards to the formwork support due to the impact. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a pump truck discharge port anti-splash device and construction method, which is especially suitable for concrete pouring operations on various foundations or floor slabs, reducing the impact of concrete pouring and improving construction quality and safety.

[0004] The technical solution adopted in this invention is: a pump truck discharge port anti-splash device, including a pipe body connection part, an anti-splash baffle and a connector. The pipe body connection part is connected to the discharge pipe of the pump truck. The anti-splash baffle is spaced apart from the outlet of the discharge pipe and connected to the pipe body connection part through the connector. The anti-splash baffle is used to receive the concrete discharged from the discharge pipe.

[0005] Furthermore, the number of connectors is multiple and they are evenly spaced along the circumference of the discharge pipe.

[0006] Furthermore, the connector is a chain-like or cable-like component to suspend the splash guard.

[0007] Furthermore, the pipe body connection is detachably connected to the discharge pipe. The pipe body connection includes multiple clamp bodies and fastening components. Splicing ears are provided at both ends of the clamp bodies. The corresponding splicing ears of adjacent clamp bodies are connected by fastening components to be fixed to the outside of the discharge pipe. At least part of the clamp bodies are connected to the corresponding connecting parts.

[0008] Furthermore, the discharge pipe is a circular pipe, and the inner surface of the clamp body is a curved surface that matches the outer wall of the discharge pipe, and its circumferential coverage area is less than a semicircle.

[0009] Furthermore, the splash guard is circular and its diameter is not less than the inner diameter of the discharge pipe.

[0010] Furthermore, the central axes of the anti-splash baffle, the pipe body connection, and the discharge pipe are set coaxially.

[0011] On the other hand, the present invention also provides a construction method for an anti-splash device at the discharge port of a pump truck, comprising the following steps:

[0012] When the pump truck is started, concrete is discharged from the discharge pipe onto the surface of the splash guard. The concrete overflows from the side of the splash guard, forming a concrete structure.

[0013] The advantages and positive effects of this invention are as follows: due to the adoption of the above technical solution, after the concrete is discharged, it first impacts the anti-splash baffle, and then overflows from the side of the anti-splash baffle after being buffered, forming a concrete structure; it has the advantages of simple structure, reducing the impact force on the foundation or formwork structure during concrete pouring, and improving the construction quality and construction safety of concrete structures.

[0022] The embodiments of the present invention will now be described with reference to the accompanying drawings. The described embodiments are only some embodiments of the invention, and not all embodiments.

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar units or units having the same or similar functions throughout.

[0024] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that terms such as "installation," "connection," and "fixing" should be interpreted broadly, and can refer to direct connection, installation, or fixing, or indirect connection, installation, or fixing. The present invention does not impose any limitations in this regard.

[0025] like Figures 1 to 6 As shown in the diagram, this invention provides an embodiment of a concrete pump truck discharge anti-splash device, including a pipe connection, an anti-splash baffle 1, and a connector 2. The pipe connection is connected to the discharge pipe 5 of the pump truck. The anti-splash baffle 1 is spaced apart from the outlet of the discharge pipe 5 and connected to the pipe connection through the connector 2. The anti-splash baffle 1 is used to receive the concrete discharged from the discharge pipe 5 and allows the concrete to overflow from its periphery. This invention eliminates the need for extensive modifications to the existing pump truck structure, enabling a change from direct impact pouring to overflow from the side of the anti-splash baffle 1 during concrete construction. This reduces the impact on the foundation or formwork structure and improves the construction quality of the concrete structure.

[0026] In this embodiment, there are multiple connectors 2, which are evenly spaced along the circumference of the discharge pipe 5. By adopting a multi-point, circumferentially distributed connection method, the stability of the anti-splash baffle 1 under the impact of concrete is significantly improved, and the possibility of its tilting and shaking is reduced.

[0027] The connector 2 is a chain-like or cable-like component used to suspend the splash guard 1. The connector 2 not only provides the necessary connection but also prevents the vibration of the discharge pipe 5 from being completely transmitted to the splash guard 1, and can accommodate minor displacements that may occur in the discharge pipe 5 during construction. Multiple connectors 2 are used to achieve multi-point balanced suspension of the splash guard 1. In this embodiment, the connector 2 is a metal chain. In other embodiments, the connector 2 can also be selected from steel wire ropes or high-strength synthetic fiber slings, depending on the specific construction scenario.

[0028] In this embodiment, the pipe body connecting part is detachably connected to the discharge pipe 5. The pipe body connecting part includes multiple clamp bodies 3 and fastening components 4. Each clamp body 3 has splicing ears 31 at both ends. Corresponding splicing ears 31 of adjacent clamp bodies 3 are connected by the fastening components 4 to be fixed to the outside of the discharge pipe 5. At least a portion of the clamp body 3 is connected to the corresponding connecting piece 2. The splicing ears 31 have insertion holes, and the fixing components can be a combination of bolts and nuts. The pipe body connecting part has a split structure, allowing it to be installed from the side of the discharge pipe 5 without needing to be inserted from the pipe end, greatly improving the convenience of installation and disassembly and adapting to complex construction site environments. The clamp bodies 3 and splicing ears 31 are integrally formed, and in this embodiment, they are prepared by bending metal sheets.

[0029] The center of the anti-splash baffle 1 in a static state corresponds to the center of the outlet of the discharge pipe 5, and the pipe body connection is configured to keep the anti-splash baffle 1 in an aligned position. In this embodiment, the discharge pipe 5 is a circular pipe. To adapt to the circular discharge pipe 5, the clamp body 3 is an arc-shaped component and the anti-splash baffle 1 is circular. In a static state, the anti-splash baffle 1 is coaxially arranged with the central axis of the pipe body connection and the discharge pipe 5. The coaxial arrangement ensures that the impact force of concrete can act perpendicularly on the center of the anti-splash baffle 1, making the force most balanced and further improving the stability of the device operation. The inner surface of the clamp body 3 is a curved surface adapted to the outer wall of the discharge pipe 5, and its circumferential coverage area is less than a semicircle. This improves the tightening effect of multiple clamp bodies 3 clamping against the outside of the discharge pipe 5 when locked by the fixing component 4. An interference fit is formed between the pipe body connection and the discharge pipe 5. The interference fit design allows the clamp body 3 to generate sufficient static friction after being locked to the discharge pipe 5, effectively preventing the device from loosening or slipping under long-term vibration and impact, thus improving the reliability of the fixation. The circular anti-splash baffle 1 has the characteristic of equal distance from the center to the edge, which can ensure that the concrete overflows evenly in all directions. Preferably, the anti-splash baffle 1 can be provided with reinforcing ribs on the side facing away from the discharge pipe 5 to improve its structural strength and impact deformation resistance.

[0030] When stationary, the orthographic projection of the anti-splash baffle 1 onto a plane perpendicular to the axis of the discharge pipe 5 completely covers the opening of the discharge pipe 5. The area of ​​the anti-splash baffle 1 is not less than the cross-sectional area of ​​the opening of the discharge pipe 5. In this embodiment, since the discharge pipe 5 is a circular pipe and the anti-splash baffle 1 is circular, the diameter of the anti-splash baffle 1 is not less than the inner diameter of the discharge pipe 5. Preferably, the diameter of the circular anti-splash baffle 1 is larger than the inner diameter of the discharge pipe 5, so that all concrete can be received and buffered.

[0031] In this embodiment, the first end of the connector 2 is connected to the first connecting part 32, and the first connecting part is connected to the corresponding clamp body 3; the second end of the connector 2 is connected to the second connecting part 11, and the second connecting part 11 is connected to the anti-splash baffle 1. There are multiple first connecting parts 32, connector 2, and second connecting parts 11, all corresponding to each other and circumferentially distributed around the axis of the discharge pipe 5. The first connecting part 32 and the second connecting part 11 can preferably be connecting rings or lifting lugs, and are fixed to the corresponding components by welding, riveting, or integral molding.

[0032] On the other hand, the present invention also provides a construction method for an anti-splash device at the discharge port of a pump truck, comprising the following steps:

[0033] The pipe body connection is installed on the outer wall of the pump truck discharge pipe 5 through the fastening assembly 4, so that the anti-splash baffle 1 is suspended directly below the pipe opening of the discharge pipe 5 and kept horizontal, with the anti-splash baffle 1 and the pipe opening of the discharge pipe 5 spaced apart.

[0034] When the pump truck is started, the concrete is discharged from the discharge pipe 5 and impacts the splash guard 1. The concrete overflows from the side of the splash guard 1 to form a concrete structure.

[0035] This invention enhances construction stability and reduces labor costs. During concrete pouring, the weight of the concrete poured onto the splash guard 1 is transferred to the end of the discharge pipe 5 through the connector 2, generating a downward stabilizing force. This helps reduce swaying at the end of the discharge pipe 5. Therefore, depending on the on-site construction conditions, one worker who would otherwise need to manually stabilize the discharge pipe 5 can be eliminated, thus reducing labor costs.

[0036] This invention also protects the foundation or formwork structure and improves the quality of concrete structures. During the pouring of the concrete structure, the high-speed discharge of concrete is caught by the splash guard 1, allowing its kinetic energy to be buffered and then discharged evenly, rather than directly impacting the foundation soil or formwork structure. This effectively reduces disturbance to the foundation soil, prevents soil particles from mixing with the concrete, and thus ensures the construction quality of the concrete cushion layer as a separator and transition layer, providing a stable foundation for the superstructure.

[0037] This invention is highly adaptable and easy to promote and apply. The device is fixed to the discharge pipe 5 through a detachable pipe body connection. Its structure can adapt to discharge pipes 5 with different outer diameters within a certain range, which improves the versatility of the device and reduces the threshold and cost of switching between different construction sites or equipment.

[0038] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
