Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, specifically to a pre-buffering device for concrete pouring of a base cushion layer using a jacking pump. Background Technology

[0002] In the construction of the foundation soil cushion layer, because the cushion layer itself is relatively thin, the impact force of the concrete pouring is large during the pouring process, which can easily cause unevenness and disturbance of the surface and base. Therefore, it is necessary to use a concrete pouring buffer device to buffer the poured concrete in order to improve the construction efficiency of the foundation soil cushion layer.

[0003] In the field of foundation soil cushion layer construction, concrete pouring is one of the core processes. Due to its high conveying efficiency and wide operating range, the overhead pump has become the mainstream equipment for cushion layer concrete pouring. However, in actual pouring operations, existing overhead pumps are limited by the design of their pump pipe structure. When the concrete is discharged from the pump pipe, it often directly impacts the surface of the foundation cushion layer. Since the foundation cushion layer itself is designed to be relatively thin, the concrete discharged from the overhead pump pipe has a large impact force. Direct impact can cause unevenness of the surface layer, such as local depressions and bulges. Subsequent secondary leveling requires additional manpower and time, which seriously affects construction efficiency. At the same time, it is impossible to guide the concrete to flow out evenly, which can easily lead to uneven pouring problems such as local accumulation and voids of concrete, failing to meet the requirements of flatness and density for cushion layer construction. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-buffering device for concrete pouring of the foundation cushion layer by a pump, which solves the problem in the background technology that direct impact will cause unevenness of the surface layer such as local depressions and bulges, which seriously affects the construction efficiency. At the same time, it cannot guide the concrete to flow out evenly, and is prone to uneven pouring problems such as local accumulation and local voids of concrete.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A pre-concrete buffer device for foundation subbase concrete pouring includes: Two connecting sleeves, a discharge pipe is installed at the bottom of the two connecting sleeves, a disassembly and assembly assembly is provided between the two connecting sleeves, and a connecting assembly is provided between the two connecting sleeves and the discharge pipe; A buffer mechanism is located at the bottom of the discharge pipe and is used to buffer the concrete pouring process. The buffer mechanism includes a buffer pad installed at the bottom of the discharge pipe and a guide plate fixedly installed on the top of the buffer pad. Multiple discharge guide grooves are opened around the buffer pad, and installation components for installing the buffer pad and the discharge pipe are provided around the buffer pad. The guide plate is conical, which enables the guide plate to effectively guide the concrete flow for the concrete pouring process.

[0006] Preferably, the installation assembly includes multiple fixing rods fixedly installed around the buffer pad and mounting plates fixedly installed on opposite sides of the multiple fixing rods. Two stabilizing bolts are screwed onto one side of each of the multiple mounting plates. The mounting plates are installed to the discharge pipe through the two stabilizing bolts. The discharge pipe is provided with a diversion assembly for diverting concrete.

[0007] Preferably, the diversion assembly includes a plurality of support plates fixedly installed on the inner wall of the discharge pipe and a diversion cylinder installed between the plurality of support plates.

[0008] Preferably, a diverting rod is installed inside the diverting cylinder, and a stabilizing connecting plate is fixedly installed inside the diverting cylinder. The diverting rod is fixed to the diverting cylinder through multiple stabilizing connecting plates, and the diverting cylinder is located above the buffer pad and the guide protrusion.

[0009] Preferably, the disassembly and assembly assembly includes a fixing plate installed on the opposite sides of the two connecting sleeves and a fixing bolt screwed between the fixing plates. The two connecting sleeves are installed by the fixing plates and the fixing bolts, and a plurality of one-to-one corresponding bolt holes are provided between the two fixing plates. The fixing bolts can be installed through the bolt holes, thereby realizing the installation and fixation of the two fixing plates and the two connecting sleeves by the fixing bolts.

[0010] Preferably, the connecting assembly includes a snap-fit ​​part fixedly installed on the top of the discharge pipe and a limiting slot formed on the inner wall of the two connecting sleeves. The snap-fit ​​part is located inside the two connecting sleeves and is inserted into the two limiting slots.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: This invention, through the design of a buffer mechanism, effectively buffers the concrete discharged from the pump's outlet pipe, significantly reducing the impact force during concrete pouring. This prevents unevenness of the foundation pad surface and disturbance of the base soil caused by excessive impact, ensuring the quality of the pad layer construction. Multiple discharge guide channels around the buffer pad guide the buffered concrete to flow out evenly, further improving the uniformity of pouring and reducing local accumulation or gaps. Combined with installation components, the buffer pad and outlet pipe can be easily and securely installed and subsequently disassembled for maintenance, reducing operational difficulty. Simultaneously, the concrete can be pre-diverted, reducing the single-bearing pressure on the buffer mechanism, extending its service life, and improving the efficiency and effectiveness of the foundation pad construction.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please refer to Figure 1 and Figure 2A pre-buffer device for concrete pouring of a base cushion layer by a concrete pump includes: two connecting sleeves 1, a discharge pipe 4 installed at the bottom of the two connecting sleeves 1, a disassembly and assembly assembly between the two connecting sleeves 1, and a connecting assembly between the two connecting sleeves 1 and the discharge pipe 4.

[0016] Please refer to Figure 3 - Figure 6 A buffer mechanism is located at the bottom of the discharge pipe 4 and is used to buffer the concrete pouring. The buffer mechanism includes a buffer pad 5 installed at the bottom of the discharge pipe 4 and a guide plate 14 fixedly installed on the top of the buffer pad 5. Multiple discharge guide grooves 11 are opened around the buffer pad 5. An installation assembly for installing the buffer pad 5 and the discharge pipe 4 is provided around the buffer pad 5. The installation assembly includes multiple fixing rods 6 fixedly installed around the buffer pad 5 and mounting plates 15 fixedly installed on the opposite sides of the multiple fixing rods 6. Two stabilizing bolts 10 are screwed to one side of each of the multiple mounting plates 15. The mounting plates 15 are installed to the discharge pipe 4 through the two stabilizing bolts 10. A diversion assembly for diverting concrete is provided inside the discharge pipe 4. First, two connecting sleeves 1 are used as the inlet components for the concrete conveying of the pump. The two connecting sleeves 1 are assembled and fixed through the disassembly and assembly components to ensure the stability of the inlet end structure. Then, the connecting components are used to achieve a stable connection between the connecting sleeves 1 and the discharge pipe 4, so that the concrete can flow smoothly from the connecting sleeves 1 into the discharge pipe 4. Subsequently, the installation components play a role, fixing the installation plate 15 to the discharge pipe 4 with the stabilizing bolts 10, thereby making the buffer plate 5 firmly installed at the bottom of the discharge pipe 4. At the same time, the diversion components divert the inflowing concrete. The diverted concrete flows to the buffer plate 5. The guide protrusion 14 on the top of the buffer plate 5 guides the concrete to disperse. Finally, the concrete flows out through multiple discharge guide channels 11 around the buffer plate 5, which not only completes the buffer treatment of concrete pouring, avoids unevenness of the foundation or disturbance of the base, but also ensures the stability and efficiency of the pouring process.

[0017] Furthermore, such as Figure 3 - Figure 6As shown, the diversion assembly includes multiple supporting plates 8 fixedly installed on the inner wall of the discharge pipe 4 and a diversion cylinder 7 installed between the multiple supporting plates 8. A diversion rod 16 is installed inside the diversion cylinder 7, and a stabilizing plate 12 is fixedly installed inside the diversion cylinder 7. The diversion rod 16 is fixed to the diversion cylinder 7 through the multiple stabilizing plates 12. The diversion cylinder 7 is located above the buffer pad 5 and the guide plate 14. Based on this, the multiple supporting plates 8 fixedly installed on the inner wall of the discharge pipe 4 provide stable installation support for the diversion cylinder 7, so that the diversion cylinder 7 can be stably placed inside the discharge pipe 4 and above the buffer pad 5 and the guide plate 14. When concrete flows into the discharge pipe 4 from the connecting sleeve 1, it will enter the diversion cylinder 7. The diversion cylinder 7 initially acts as a diversion cylinder for the concrete. The distribution and guiding function prevents the concrete from concentrating and impacting the buffer mechanism below. Simultaneously, the diversion cylinder 7 is fixedly installed with diversion rods 16 via multiple stabilizing connecting plates 12. The stabilizing connecting plates 12 ensure the stable position of the diversion rods 16 within the diversion cylinder 7. When concrete enters the discharge pipe 4 and the diversion cylinder 7, the diversion rods 16 and supporting connecting plates 8 further subdivide the concrete, dividing it into multiple small-flow streams. This allows the concrete to flow more evenly towards the buffer pad 5 and the guide plate 14 below, reducing the impact pressure of the concrete on the buffer mechanism and laying the foundation for the subsequent even discharge of concrete from the buffer pad 5 through the discharge guide chute 11. This improves the uniformity and buffering effect of the concrete pouring, preventing unevenness of the subgrade or disturbance of the foundation due to impact.

[0018] Furthermore, such as Figure 1 - Figure 3 As shown, the assembly and disassembly components include fixing plates 2 installed on opposite sides of the two connecting sleeves 1 and fixing bolts 3 screwed between multiple fixing plates 2. The two connecting sleeves 1 are installed through the fixing plates 2 and fixing bolts 3. Based on this, the two connecting sleeves 1 serve as inlet connecting components for concrete conveying. When it is necessary to assemble the two to form a complete inlet channel, first align and fit the fixing plates 2 on opposite sides of the two connecting sleeves 1 so that the bolt holes on the fixing plates 2 are precisely aligned. Then, screw the fixing bolts 3 between the aligned fixing plates 2. By tightening the fixing bolts 3, the two fixing plates 2 are firmly locked by the tightening force of the bolts, thereby driving the two connecting sleeves 1 to be stably connected as one, ensuring that subsequent concrete can flow smoothly from the connecting sleeves 1 into the lower discharge pipe 4. When it is necessary to disassemble or repair the connecting sleeves 1, simply loosen and remove the fixing bolts 3 to release the two fixing plates 2 from the locked state, and the two connecting sleeves 1 can be separated. The whole process is simple to operate and can flexibly meet the installation and maintenance needs of the device in different construction scenarios, ensuring the continuity of concrete pouring operations.

[0019] Furthermore, such as Figure 1 - Figure 3As shown, the connecting assembly includes a snap-fit ​​part 9 fixedly installed on the top of the discharge pipe 4 and a limiting slot 13 opened on the inner wall of the two connecting sleeves 1. The snap-fit ​​part 9 is located inside the two connecting sleeves 1 and is inserted into the two limiting slots 13. Based on this, firstly, the snap-fit ​​part 9 at the top is aligned with the bottom opening of the two connecting sleeves 1. Then, the snap-fit ​​part 9 is pushed into the interior of the two connecting sleeves 1, so that the snap-fit ​​part 9 and the limiting slot 13 opened on the inner wall of the connecting sleeve 1 are precisely aligned and inserted into the limiting slot 13. Through the snap-fit ​​cooperation between the snap-fit ​​part 9 and the limiting slot 13, the relative displacement between the discharge pipe 4 and the connecting sleeve 1 can be restricted, avoiding the two from falling off or shifting due to vibration or concrete impact during concrete transportation. At the same time, the two connecting sleeves 1 can be disassembled to separate the discharge pipe 4 from the connecting sleeve 1, thus ensuring the stability and flexible disassembly and assembly of the concrete transportation channel.
