Description

Technical Field

[0001] This utility model belongs to the field of concrete pouring, and specifically relates to a synchronous concrete pouring device with a grout leakage prevention and interception structure. Background Technology

[0002] In the construction of infrastructure projects such as power and communications, cable trenches are a critical structure, and their structural quality directly affects the safety and stability of the entire project. These cable trenches are usually designed as long, narrow, and parallel double-channel structures, making concrete pouring a challenging and critical construction process.

[0003] Currently, there are two main construction methods for pouring concrete into this type of double-trough structure. The first method uses a single pump pipe combined with a manually operated flexible hose to alternately pour concrete into the two trenches. This method has significant drawbacks: firstly, manual operation is difficult to control precisely, resulting in low pouring efficiency; secondly, and more seriously, this alternating pouring cannot guarantee that the filling speed and height of the concrete in the two trenches are synchronized, which can easily cause uneven settlement of the structure and create safety hazards for subsequent operation.

[0004] The second method involves symmetrically arranging independent pump pipes on both sides of the ditch for pouring. However, this method has certain problems in practical applications: the connection device lacks effective flow control functionality.

[0005] Specifically, when a sudden situation occurs, such as a blockage or need for replacement of the pump pipe on one side, construction workers cannot quickly and effectively cut off the material flow on that side alone. This leads to two consequences: if the fault is to be dealt with, the entire pumping system must be stopped, which forces the normal pouring operation on the other side to be interrupted, disrupting the continuity of the concrete and making it prone to cold joints; if the pump is not stopped, the concrete will continue to leak from the faulty side, causing serious waste of resources and safety risks.

[0006] Therefore, a synchronous concrete pouring device with a grout leakage prevention and interception structure is needed. This device needs to meet the following key requirements: first, it should be able to achieve synchronous and uniform pouring in both tanks; second, it should be able to achieve rapid and reliable individual interception when one side of the pipeline fails. Utility Model Content

[0007] To address the aforementioned problems, this utility model provides a synchronous concrete pouring device with a grout leakage prevention and interception structure, thereby achieving the goal of solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a synchronous concrete pouring device with a grout leakage prevention and interception structure, comprising: a feed pipe with a feed end at the top adapted to the discharge port of a concrete pump truck; and multiple chute pipes, all of which are connected and arranged at the bottom of the feed pipe.

[0009] As a further improvement to the above technical solution:

[0010] Both the feed pipe and the chute pipe are equipped with flow-blocking structures.

[0011] The flow-blocking structure includes:

[0012] Insertion slots are provided on the feed pipe and chute pipe; and insertion plates are hinged to one side of the insertion slots and used in conjunction with the insertion slots to cut off the internal channels of the feed pipe and / or chute pipe and to adjust the opening of the internal channels of the feed pipe and / or chute pipe.

[0013] The insert plate has a handle protruding from the insertion slot on one side.

[0014] There are two chute pipes, which are symmetrically arranged in a figure-eight shape at the bottom of the feed pipe.

[0015] The bottom of the chute is connected to a discharge section, and the bottom of the discharge section is provided with a flattening groove that is adapted to the width of the cable trench.

[0016] The feed pipe is equipped with a handle.

[0017] The feed pipe and the chute pipe are provided with vent holes; the vent holes are located on the upper inclined side of the chute pipe.

[0018] The beneficial effects of this utility model embodiment are as follows:

[0019] This application achieves synchronous concrete pouring of cable trenches by setting multiple chute pipes at the bottom of the feed pipe, ensuring uniform filling of the trench. It has the advantage of being able to achieve synchronous concrete pouring, avoiding uneven stress distribution caused by asynchronous pouring, thereby reducing the risk of structural cracking and settlement.

[0020] By installing flow-blocking structures on both the feed pipe and the chute pipe, a multi-level independent flow-blocking control mechanism was constructed. The flow-blocking structure on the feed pipe is mainly used for rapid cutoff in the event of a global anomaly, which can block the flow of concrete at the source and provide a basic guarantee for the overall maintenance of the system; while the flow-blocking structure on the chute pipe enables independent control of each chute pipe.

[0021] The combination of the insert plate and the insertion slot allows construction workers to insert or remove the insert plate with one hand, thus completing the flow interception operation with one hand, which significantly improves operational efficiency.

[0022] When used in conjunction with the insertion slot, the insert plate can also adjust the opening of the internal channels of the feed pipe and / or chute pipe; by inserting the insert plate to different depths, an arbitrary size of channel opening area can be obtained; for chute pipes used for pouring thinner trenches, the insert plate can be appropriately closed to reduce the concrete flow rate and prevent concrete overflow or waste. Precise flow control through the insert plate and insertion slot effectively avoids the problem of excessive concrete accumulation or insufficient filling in the trench. Attached Figure Description

[0030] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] See Figure 1-4 This utility model discloses a concrete synchronous pouring device with a grout leakage prevention and interception structure, including: a feed pipe 1 with a feed end at the top adapted to the discharge port of a concrete pump truck; and multiple chute pipes 2, all of which are connected and arranged at the bottom of the feed pipe 1.

[0033] The feed pipe 1 can be understood as the main channel for receiving and transmitting concrete. Its top feed end is designed to directly connect to the discharge port of the concrete pump truck. In practical applications, the feed end can be fixed to the pump truck discharge port via flange connection, snap-fit ​​connection, or threaded connection to ensure the stability of the concrete input process. Furthermore, the internal channels of the feed pipe 1 can be lined with an anti-stick and wear-resistant material to optimize the concrete flow characteristics, thereby reducing the risk of blockage and improving conveying efficiency.

[0034] The number and layout of the chute pipes 2 can be adjusted according to actual construction needs. For example, there can be two, three, or four chute pipes 2, connected to the bottom of the feed pipe 1. The distribution of the chute pipes 2 can be in a straight line, a ring, or other geometric shapes to adapt to the space constraints and pouring requirements of different construction sites. The design of the chute pipes 2 is mainly used to divert concrete to multiple target areas, thereby achieving the effect of synchronous pouring.

[0035] By integrating multiple chute pipes 2 into the feed pipe 1, the technical problem of synchronous and uniform concrete pouring in the construction of double- or multi-groove cable trench structures is solved. It also provides a physical basis for rapid shut-off operations in case of unilateral pipeline failure. Compared to existing technologies that involve manually swinging flexible hoses or independently laying pump pipes, this device effectively avoids the risk of structural settlement caused by differences in pouring speed and significantly improves the controllability of the construction process. Furthermore, the interconnected configuration of multiple chute pipes 2 facilitates the installation and operation of the subsequent shut-off structure 3, thereby preventing concrete leakage and ensuring the continuity of pouring operations.

[0036] The working principle of this embodiment is as follows: Through the integrated design of the feed pipe 1 and multiple chute pipes 2, synchronous and uniform concrete pouring is achieved, and rapid interception can be implemented to prevent grout leakage in the event of a single-sided pipeline failure. The top of the feed pipe 1 is equipped with a feed end adapted to the discharge port of the concrete pump truck. The chute pipes 2 divert the concrete, avoiding the low pouring efficiency and positional deviation problems caused by traditional manual swinging of the hose, thereby ensuring the stability and accuracy of concrete input. Furthermore, multiple chute pipes 2 are all connected and arranged at the bottom of the feed pipe 1. This layout diverts the concrete from a single feed point to multiple channels, achieving synchronization and uniformity in the pouring process. Specifically, the interconnected arrangement of multiple chute pipes 2 not only reduces the risk of structural settlement caused by differences in pouring speed, but also provides a physical basis for subsequent interception operations. Thus, in the event of a blockage or failure in a single-sided pipeline, the interception structure 3 can be quickly located and operated to cut off the corresponding chute pipe 2, preventing concrete leakage and ensuring the continuity of the pouring operation and resource utilization.

[0037] See Figure 1-2This application further proposes that both the feed pipe 1 and the chute pipe 2 are equipped with intercepting structures 3. The intercepting structure 3 is a device that can quickly block or restore the flow of concrete; its purpose is to provide flexible flow channel control capabilities, ensuring rapid response and precise isolation of the target area in case of emergencies, thereby avoiding overall shutdown or waste of resources due to unilateral failure.

[0038] By installing intercepting structures 3 on both the feed pipe 1 and the chute pipe 2, a multi-level independent interception control mechanism is constructed. The intercepting structure 3 on the feed pipe 1 is mainly used for rapid cutoff in the event of a global anomaly, blocking the concrete flow at the source and providing a basic guarantee for the overall maintenance of the system. The intercepting structure 3 on the chute pipe 2, on the other hand, enables independent control of each chute pipe 2. When a chute pipe 2 becomes blocked or needs to be replaced, only the corresponding intercepting structure 3 needs to be operated to precisely block the local material flow, while other chute pipes 2 can still maintain normal pouring operations. This design not only solves the problem of inaccurate isolation when a single-sided pipeline fails, but also enhances the targeting and reliability of the operation through structured location distribution, enabling the device to respond flexibly to emergencies and ensuring the stability and construction quality of the concrete pouring process.

[0039] See Figure 1-3 This application further proposes a flow-cutting structure 3 including: a plug groove 31, which is formed on the feed pipe 1 and the chute pipe 2; and a plug plate 32, which is hinged to one side of the plug groove 31 and is used in conjunction with the plug groove 31 to cut off the internal channels of the feed pipe 1 and / or the chute pipe 2.

[0040] The insertion slot 31 is a through-slot structure used for positioning and guidance. Its purpose is to provide a precise insertion path for the insertion plate 32, ensuring that the insertion plate 32 can quickly and accurately complete the flow-stopping operation. In practical applications, the insertion plate 32 can be understood as a rotatable baffle structure, which is connected to one side of the insertion slot 31 via a hinge, thereby achieving an opening and closing action based on the principle of rotational motion. This design allows construction personnel to insert or remove the insertion plate 32 with one hand, significantly improving operational efficiency.

[0041] This application constructs an efficient and reliable flow-blocking system through the synergistic action of the insertion slot 31 and the insert plate 32. The insertion slot 31, positioned on the inlet pipe 1 and the chute pipe 2, provides a clear positioning reference for the insert plate 32, ensuring precise alignment in every operation. The insert plate 32, hinged to one side of the insertion slot 31, simplifies the operation process using rotational motion, enabling rapid response by construction personnel in emergencies. When the insert plate 32 is inserted into the insertion slot 31, the tight fit between the two effectively blocks concrete flow. This design not only ensures rapid isolation in case of unilateral pipe failure but also does not affect the normal pouring operations of other pipes, thus solving the problem of construction interruption or material waste caused by the lack of an efficient flow-blocking mechanism.

[0042] The "thickness" (i.e., the opening width of the gap) of the spigot 31 is small. It is smaller than the typical particle size of the main coarse aggregates (such as gravel and crushed stone) in concrete. This means that the aggregate particles that play a skeletal role in the concrete cannot pass through this narrow gap at all, preventing leakage through the spigot 31.

[0043] Meanwhile, concrete is not a homogeneous fluid, but a mixture of water, cement, sand (fine aggregate), and stone (coarse aggregate). The coarse aggregate forms the solid skeleton of the mixture. Because the opening of the spigot 31 is smaller than the particle size of the coarse aggregate, these aggregates overlap and interlock at the inlet of the spigot 31, forming a natural "filter" that effectively blocks subsequent mortar and cement paste from passing through.

[0044] Furthermore, the spigot groove 31 is not located at the bottom of the chute pipe 2, but rather on its upward-sloping side, where concrete mainly accumulates and flows through the bottom of the pipe under gravity. The upper spigot groove 31 avoids the core pressure and impact zone of the main concrete flow, and the static pressure head it bears is extremely small. Similarly, on the feed pipe 1, the spigot groove 31 is also located on the side, which also avoids directly bearing the frontal impact and maximum static pressure from the vertically falling material above; further preventing concrete leakage through the spigot groove 31. Even if concrete leaks through the spigot groove 31, due to the small opening width of the spigot groove 31, the extremely small amount of concrete leakage will not affect normal use.

[0045] When used in conjunction with the insertion slot 31, the insert plate 32 can also adjust the opening of the internal channels of the feed pipe and / or chute pipe. The thickness of the cable trench is not constant; it may vary due to terrain and design requirements (such as main trench versus branch trench, road crossing versus regular section). By inserting the insert plate 32 to different depths, an arbitrary channel opening area can be obtained. For chute pipe 2 with a thinner trench, the insert plate 32 can be appropriately closed to reduce the concrete flow and prevent concrete overflow or waste. By precisely controlling the flow rate through the insert plate 32 and insertion slot 31, the problem of excessive concrete accumulation or insufficient filling in the trench can be effectively avoided.

[0046] See Figure 3 This application further proposes that a handle 33 protruding from the insertion slot 31 is provided on one side of the insertion plate 32. The handle 33 is an auxiliary component that facilitates the operator's gripping and force application, and it can be implemented in a cylindrical, rectangular, or other geometry suitable for gripping. In practical applications, the handle 33 is fixed to one side of the insertion plate 32 by welding, bolting, or integral molding. Its purpose is to provide the construction personnel with a clear and easy-to-operate point of force, thereby improving the convenience and efficiency of the interception operation. The design of the handle 33 protruding from the insertion slot 31 ensures that it is always exposed outside the insertion slot 31 and is not obstructed by the insertion slot 31.

[0047] This application further proposes that there are two chute pipes 2, which are symmetrically arranged in a figure-eight shape at the bottom of the feed pipe 1.

[0048] When there are two chute pipes 2, it matches the double-groove structure of the cable trench. In practical applications, this number ensures that each trench in the double-groove cable trench has an independent and dedicated concrete conveying channel, avoiding the problem of chaotic flow distribution due to redundancy or insufficiency. The "figure-eight" symmetrical layout refers to the arrangement of the two chute pipes 2 with the central axis of the feed pipe 1 as the axis of symmetry. The purpose is to use the symmetrical geometry to guide the concrete to flow evenly from the feed pipe 1, so that the concrete flow path under gravity naturally adapts to the spacing between the two trenches, thereby reducing the flow difference on both sides.

[0049] This application further proposes that the bottom of the chute pipe 2 is connected to a discharge section, and the bottom of the discharge section is provided with a flattening groove adapted to the width of the cable trench. By adding a discharge section to the bottom of the chute pipe 2, the concrete can be concentrated and guided before flowing out, avoiding the problem of scattering. At the same time, the flattening groove at the bottom of the discharge section, because its width precisely matches the trench of the cable trench, can restrict the concrete flow within the trench area, fundamentally solving the problem of grout leakage.

[0050] This application further proposes that a handle 4 be provided on the feed pipe 1. The handle 4 is a structural component that is easy for construction personnel to grip, and it can be made of metal rods or composite materials. In practical applications, the handle 4 can be fixed to the outer wall of the feed pipe 1 by welding, bolting, or integral molding. Its purpose is to provide operators with a stable grip point and avoid inconvenience caused by the slippery surface of the feed pipe 1.

[0051] This application further proposes that vent holes 5 be provided on the feed pipe 1 and the chute pipe 2; the vent holes 5 are located on the upward-sloping side of the chute pipe 2. The vent hole 5 refers to a through-hole structure opened on the feed pipe 1 and the chute pipe 2 for discharging internal air, which can be implemented in the form of a circular, elliptical, or strip-shaped hole. In practical applications, the location of the vent hole 5 needs to be selected in conjunction with the key nodes of the concrete flow path to ensure that air can escape in a timely manner. Its purpose is to solve the problems of uneven filling and grout leakage caused by air resistance during concrete pouring.

[0052] Specifically, by installing vent holes 5 on the feed pipe 1 and the chute pipe 2, the problem of air trapping during concrete flow is effectively addressed. The vent holes 5 are positioned along the critical flow paths of concrete entering the device from the pump truck and being diverted to the dual chute, allowing air to be discharged promptly through the vent holes 5 during the initial flow stage of the concrete, preventing air bubbles from accumulating and forming localized high pressure. This design not only ensures the continuous and uniform flow of concrete but also reduces filling defects caused by air resistance. Furthermore, when it is necessary to cut off the material flow separately, the presence of the vent holes 5 can prevent air pressure from interfering with the sealing effect of the insert plate 32.

[0053] In actual installation, the chute pipe 2 is inclined, for example, arranged symmetrically in a figure-eight shape. The vent 5 is located on the upper inclined side of the chute pipe 2, making the upper inclined side the highest point of the pipe. Placing the vent 5 in this position fully utilizes gravity and the rising characteristics of gas, allowing accumulated air to be directly captured and released. The connection structure between the feed pipe 1 and the chute pipe 2, combined with the placement of the vent 5, forms a complete venting system. When concrete flows through the chute pipe 2, the gas naturally moves upward and is discharged through the vent 5, achieving synchronization between the venting process and the concrete flow. This design not only solves the problem of air stagnation in inclined pipes but also, to a certain extent, prevents concrete from clogging the vent 5.
