Description

Technical Field

[0001] The present invention relates to the technical field of concrete pouring, and in particular to a method and a device for pouring large-volume concrete. Background Art

[0002] For electric boiler installation work, the pouring and molding process of the concrete base is the most basic and critical step. First of all, it is necessary to ensure that the surface flatness deviation is ≤5mm, the verticality deviation is ≤H / 1000 and ≤30mm, and considering the difficulty of the operation, the concrete prefabrication method is not used but on-site one-piece casting is adopted.

[0003] In terms of the operating characteristics of electric boilers, the concrete base is affected by factors such as operating temperature, operating load, and operating vibration. Therefore, the concrete must have sufficient volume and solidity to bear the weight and operating load of the electric boiler, and possess two key characteristics: vibration protection and thermal stress deformation protection. The concrete pouring process is explained with specific reference to the relevant contents in publication numbers CN118814569A and CN113146835A. The essence is to improve the compactness of the concrete slurry and reduce the amount of bubbles by using a vibrator. In order to meet the requirement of thermal stress deformation protection, most of the methods use pre-buried pipes (as heat dissipation channels). However, it is difficult for the pipes to provide stable supporting force. Even after being put into operation, the stress generated during the solidification of the concrete, the load of the electric boiler equipment or the operating vibration may cause the pipes to deform, which directly affects the structural stability of the entire concrete base. If a heat dissipation method is not adopted, the internal temperature of the concrete base is difficult to dissipate in time. In addition, the concrete solidification process is an exothermic process. If the temperature heat dissipation effect is not good, the internal temperature rise gradient will also cause the concrete base to dry out and crack. This application proposes a solution to this problem. Summary of the Invention

[0004] The purpose of the present invention is to provide a large-volume concrete pouring method and pouring device. For the concrete base used in electric boilers, it must meet the requirements of sufficient volume and solidity to meet the weight and operating load of the electric boiler equipment, and it is also necessary to further meet the functions of vibration prevention and control and thermal stress deformation protection. However, in the actual construction process, a single vibration method is difficult to meet the construction requirements, and there may be problems such as structural instability or poor heat dissipation.

[0005] The object of the present invention can be achieved by the following technical solution: a large-volume concrete pouring method, using a concrete grouting group and an oscillator, is applied to the pouring process of the electric boiler concrete platform base, including four steps of frame construction, initial pouring, post-pouring and reinforcement and finishing, and includes the following contents: Frame construction: Lay out the base frame according to the installation position of the electric boiler, and weld the heat dissipation pipe group along its length in the base frame; Initial pouring process: concrete slurry is poured into the interior of the base frame by the concrete grouting group to form an initial filling area in the base frame, and a blank area is formed on the upper side of the base frame corresponding to the initial filling area. The height of the initial filling area is greater than two-thirds of the height of the base frame, and the heat dissipation pipe group is located in the initial filling area; Post-casting process: During the initial casting process, the primary filling area is vibrated and intensified by an oscillator, and then enters the initial setting stage. After the initial setting stage is completed, the concrete grouting group is used to pour concrete slurry into the blank area during the initial casting process and simultaneously vibrate and intensify it to form the post-fill area. The surface of the post-fill area is flush with the upper surface of the base frame; Reinforcement and finishing: After the post-pouring process is completed, the upper end cap is covered on the base frame, and the sleeve cone is inserted into the backfill area and the primary filling area in the vertical direction through the upper end cap, and the upper end cap is removed. The internal water cooling circulation action is performed through one or more of the heat dissipation pipe groups. The primary filling area is vibrated and encrypted through the oscillator and another heat dissipation pipe group, and the surface of the backfill area is leveled.

[0006] The present invention also proposes a large-volume concrete pouring device, which is used in the above-mentioned large-volume concrete pouring method, including a base frame, a transverse sleeve, and an upper end cap. The transverse sleeve is inserted into the base frame along a direction parallel to the length of the base frame, and the transverse sleeve is linearly and equidistantly arranged along the width direction of the base frame.

[0007] It is further configured that: a linear distance between the center point of the transverse sleeve and the bottom surface of the base frame is greater than half of the height of the base frame.

[0008] It is further configured as follows: both ends of the transverse sleeve extend to the external position of the base frame and are provided with sleeve caps through threaded connection, and the sleeve caps are provided with a water outlet and a fixing port.

[0009] It is further configured as follows: the lower end of the plug cone is conical and hollow, and the length of the plug cone is greater than two-thirds of the height of the base frame, and the upper end cap is provided with a mounting opening corresponding to the plug cone.

[0010] It is further configured as follows: a pressure sleeve group is linearly and equidistantly arranged on the transverse sleeve along its length direction, and the pressure sleeve group consists of a ring and two pressure arc plates. The ring is welded on the transverse sleeve, and the pressure arc plates are welded on the upper and lower sides of the ring in the vertical direction.

[0011] It is further configured that: the lateral cross section of the compressed arc plate is in a curved arch shape along the direction close to the transverse sleeve.

[0012] It is further configured as follows: a reinforcement plug rod is provided in the transverse sleeve through the fixing port, the outer wall of the reinforcement plug rod matches the inner wall of the transverse sleeve, and a water trough is provided between the reinforcement plug rod and the inner wall of the transverse sleeve.

[0013] The present invention has the following beneficial effects: 1. Based on the conventional layered concrete pouring method, and specifically tailored to the requirements of the concrete base platform for electric boilers, the overall platform structure must first have good structural strength. The key lies in the transverse sleeves pre-embedded during pouring. The transverse sleeves are mainly used to meet the heat dissipation channel during the operation of the electric boiler. The transverse sleeves form an integrated structure after the concrete slurry is completely solidified. To ensure the structural strength of the base platform, reinforcement rods can also be inserted into the transverse sleeves to avoid the risk of cracking due to uneven stress distribution caused by the operating load of the electric boiler. 2. Further explanation of the overall pouring process: First, a layered pouring method is used to ensure that the transverse sleeves are completely immersed in the concrete layer. To address this, a compression sleeve is further added to the transverse sleeves to ensure that they are completely immersed in the concrete layer. The key lies in the compression arc plates at the upper and lower sides of the compression arc plates. The compression arc plates serve as the "force transfer" structure for the transverse sleeves to withstand the operating load of the electric boiler. Based on the reinforcement of the internal support of the plug rod, they can also improve the vibration resistance of the overall concrete base platform by dispersing the stress generated by the operating load of the electric boiler. 3. Further explanation of the transverse sleeve: The transverse sleeve not only serves as a heat dissipation channel, but also as a water cooling channel and an oscillation channel during the solidification period of concrete. During the solidification period of concrete, the temperature gradient inside the concrete layer can be reduced by injecting into the interior of the transverse sleeve. Alternatively, a structure such as an oscillating rod in an oscillator can be directly inserted into the transverse sleeve, thereby continuously and indirectly vibrating the concrete during solidification to produce bubbles and thus play a reinforcement role.

[0017] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1: The concrete base used in electric boilers must have sufficient volume and solidity to meet the weight and operating load of the electric boiler equipment. It also needs to meet the functions of vibration prevention and thermal stress deformation protection. However, in actual construction, a single vibration method is difficult to meet the construction requirements and may cause structural instability or poor heat dissipation. In this regard, the following technical solution is proposed: Reference Figure 1-Figure 7 In this embodiment, a large-volume concrete pouring method uses a concrete grouting group and an oscillator and is applied to the pouring process of the electric boiler concrete platform base. The method includes four steps: frame construction, initial pouring, post-pouring, and reinforcement and finishing. The method also includes the following contents: Frame construction: Lay out the base frame according to the installation position of the electric boiler, and weld the heat dissipation pipe group along its length in the base frame; Initial pouring process: concrete slurry is poured into the base frame through the concrete grouting group to form an initial filling area in the base frame, and a blank area is formed on the upper side of the base frame corresponding to the initial filling area. The height of the initial filling area is greater than two-thirds of the height of the base frame, and the heat dissipation pipe group is located in the initial filling area; Post-casting process: During the initial casting process, the primary filling area is vibrated and intensified by an oscillator, and then enters the initial setting stage. After the initial setting stage is completed, the concrete grouting group is used to pour concrete slurry into the blank area during the initial casting process and simultaneously vibrate and intensify it to form the post-fill area. The surface of the post-fill area is flush with the upper surface of the base frame; Reinforcement and finishing: After the post-pouring process is completed, the upper end cap is covered on the base frame, and the sleeve cone is inserted into the backfill area and the primary filling area in the vertical direction through the upper end cap, and the upper end cap is removed. The internal water cooling circulation action is performed through one or more of the heat dissipation pipe groups. The primary filling area is vibrated and encrypted through the oscillator and another heat dissipation pipe group, and the surface of the backfill area is leveled.

[0019] Among them, a large-volume concrete pouring device is used in the above-mentioned large-volume concrete pouring method, including a base frame 1, a transverse sleeve 5, and an upper end cap 3. The transverse sleeve 5 is inserted into the base frame 1 along a direction parallel to the length of the base frame 1, and the transverse sleeve 5 is linearly and equidistantly arranged along the width direction of the base frame 1.

[0020] Basic Principle: A brief description of the pouring process of the concrete platform: its essence is to inject a fixed amount of concrete slurry, and then use a device such as a vibrator to vibrate the concrete slurry to remove bubbles and make it denser. However, the present invention is mainly aimed at the pouring process of the concrete base platform of the electric boiler. First of all, for the operation process of the electric boiler, on the one hand, there are the problems of setting the load and vibration during operation, and secondly, the high temperature problem during the operation of the electric boiler. If the pouring is carried out in a conventional manner, first of all, the high temperature problem directly affects the concrete base platform, and local cracking may occur. In particular, the high load and vibration problem aggravates the problem of local cracking. The present invention optimizes a casting method in this way. First, the base frame 1 is set up according to the installation position of the electric boiler. Figure 2 For example, the base frame 1 is essentially formed by combining three or more support plates. First, each support plate is enclosed into a complete closed loop area, and the support plate is directly fixed to the ground by bolts. The interior of the base frame 1 is used as the pouring area for the concrete slurry. However, it is different from the conventional method in that: a transverse sleeve 5 needs to be welded along the length direction of the base frame 1, and the transverse sleeve 5 serves as a heat dissipation pipe group. A plurality of pressure sleeves 6 are further welded on the transverse sleeve 5. It is also necessary to ensure that both ends of the transverse sleeve 5 are open and extend to the outside of the base frame 1. The use of the concrete grouting group and the oscillator is not described in detail in the present invention. It should be noted that when the concrete grouting group is used to inject the concrete grouting into the base frame 1, it is necessary to ensure that the liquid level of the concrete grouting is greater than two-thirds of the base frame. Figure 3, only the initial filling area that completely wraps the horizontal sleeve 5 is formed. When the concrete slurry in the initial filling area completes the initial setting, the next pouring is carried out to make the overall concrete slurry level completely parallel to the base frame.

[0021] Example 2: Based on Example 1, the two pouring processes are described as follows: The linear distance between the center point of the horizontal sleeve 5 and the bottom surface of the base frame 1 is greater than half the height of the base frame 1. The two ends of the horizontal sleeve 5 extend to the external position of the base frame 1 and are provided with a sleeve cap 2 by a threaded connection. The sleeve cap 2 is provided with a water inlet 202 and a fixing port 201. The lower end of the plug cone 4 is conical and hollow, and the length of the plug cone 4 is greater than two-thirds of the height of the base frame 1. The upper end cap 3 is provided with a mounting port corresponding to the plug cone 4. The horizontal sleeve 5 is linearly and equidistantly provided with a pressure sleeve group 6 along its length direction. The pressure sleeve group 6 consists of a collar 602 and two pressure arc plates 60 1, the collar 602 is welded to the transverse sleeve 5, and the pressure arc plate 601 is welded to the upper and lower sides of the collar 602 in the vertical direction. The lateral cross-section of the pressure arc plate 601 is in a curved arch shape along the direction close to the transverse sleeve 5. A reinforcement plug rod 7 is provided in the transverse sleeve 5 through the fixing port 201. The outer wall of the reinforcement plug rod 7 matches the inner wall of the transverse sleeve 5, and a water groove 501 is provided between the reinforcement plug rod 7 and the inner wall of the transverse sleeve 5. The fixing port 201 is mainly used to fix the reinforcement plug rod 7. Conversely, the water port 202 is mainly used as a water inlet structure when low-temperature water or normal-temperature water is pumped into the transverse sleeve 5.

[0022] Solution description: During the initial pouring process, the purpose of ensuring that the concrete slurry level must be greater than two-thirds of the height of the base frame 1 is to ensure that the concrete slurry completely covers the pressure set 6. For details, refer to Figure 6 Due to the structural limitations of the compressed arc plate 601, it is necessary to ensure that the concrete slurry is completely filled in the lower position of the lower compressed arc plate 601 with the assistance of an oscillator to avoid the problem of insufficient volume in the overall initial filling area. The post-casting process is carried out after the initial setting of the primary filling area is completed. In this process, it should be noted that the initial setting stage represented in the present invention is mainly to complete the preliminary shaping of the primary filling area but does not mean that the primary filling area has solidified. The initial setting stage also includes the following actions: Action 1: Perform an internal water cooling circulation action on one or more of the transverse sleeves 5. Then, the transverse sleeves 5 at this stage are represented as the heat dissipation pipe group in the casting method. The internal water cooling circulation action is used to avoid obvious temperature differences in the primary filling area. The temperature of the liquid injected into the transverse sleeves 5 during the internal water cooling circulation action is controlled according to the temperature range existing during the solidification of the concrete, thereby representing the heat dissipation internal channel.

[0023] Action 2: During the initial pouring process, the vibrating rod in the vibrator is in direct contact with the concrete slurry. During the initial setting stage, the vibrating rod can be inserted into the transverse sleeve 5. In addition to water cooling, the concrete slurry in the initial filling area can be indirectly vibrated by indirect contact. The vibrating rod can also be synchronized with the initial filling area to further improve the compactness of the concrete slurry. In the post-casting process, Figure 3 The blank area in the base frame is filled, and the oscillator is also required to perform oscillation processing in this process. The key point is: after the pouring process of the blank area is completed, the overall base frame 1 is directly covered with the upper end cap 3, so a relatively closed area is formed inside the overall base frame 1. In this process, the insert cone 4 is inserted in a completely vertical direction through the upper end cap 3. It should be noted that: because the interior of the base frame 1 has been completely filled with concrete slurry, but because of the process of inserting the insert cone 4, the internal volume of the base frame 1 is "reduced", and the filled concrete slurry is compressed, thereby further improving the compactness of the concrete slurry. After a period of time, ensure that the concrete slurries in the post-fill area and the primary filling area have entered a solidified state, then remove the upper end cap 3 and level the surface; Finally, the process is to wait for the complete solidification of the concrete slurry. While waiting for complete solidification, the above-mentioned internal water cooling circulation action and vibration encryption action can also be carried out simultaneously. The two actions do not need to be carried out continuously, and their working time can be set. For example, after the internal water cooling circulation action and vibration encryption action are carried out for 2 hours, the vibrating rod is pulled out to stop pumping water into the transverse sleeve 5, and a reinforcement plug rod 7 is inserted into each transverse sleeve 5 to avoid deformation of the transverse sleeve 5 when the concrete slurry is completely solidified. The explanation of the reinforcing plug rod 7 is that the reinforcing plug rod 7 is essentially a metal rod that completely matches the inner wall of the transverse sleeve 5, but in order to ensure liquid circulation, a water groove 501 matching the length of the transverse sleeve 5 is opened on the outer surface of the reinforcing plug rod 7. This is explained with respect to the heat dissipation process: during the pouring process or the subsequent use process, the reinforcing plug rod 7 is inserted into the transverse sleeve 5. The reinforcing plug rod 7 provides external support force to the inside of the transverse sleeve 5, but because the water groove 501 provided on the outer wall of the reinforcing plug rod 7 results in a water flow channel inside the reinforcing plug rod 7, low-temperature water or normal temperature water is injected into one end of the transverse sleeve 5, and the water body can flow through the water groove 501 to perform an indirect heat exchange process with the concrete.

[0024] Example 3: Based on Example 2, the operation of the formed concrete base platform is explained: In conjunction with the second embodiment, after the entire concrete slurry is completely solidified, the base frame 1 does not need to be removed. After the electric boiler is installed on the solidified concrete base platform, and during the operation of the electric boiler, on the one hand, static room temperature water can be injected into each plug cone 4, and on the other hand, room temperature water can be continuously pumped into the horizontal sleeve 5. The room temperature water flows at a slow flow rate to maintain the temperature difference inside the concrete base platform with room temperature water. Figure 6 During the operation of the electric boiler, the pressure arc plate 601 will be subjected to stress caused by the vibration of the electric boiler. However, due to the structural characteristics of the pressure arc plate 601, it can be directly understood that the transverse casing is subjected to upward and downward stresses respectively, and the two are balanced and offset. Specifically, the pressure arc plate 601 is used as the load-bearing internal structure to Figure 6 For example, when the upper pressure arc plate 601 bears concrete, due to the structural characteristics of the upper pressure arc plate 601, it can be understood that downward pressure is directly generated on the transverse sleeve 5. However, due to the structural characteristics of the lower pressure arc plate 601, the downward pressure transmitted to the transverse sleeve 5 will be transferred to the lower pressure arc plate 601, so that the stress generated by the concrete at the upper position is still transferred to the concrete at the lower position through the transfer of the two pressure arc plates 601. Especially during the operation of the electric boiler, the vibration generated by the operation of the electric boiler is indirectly transmitted to the transverse sleeve 5. However, through the transmission process of the two pressure arc plates 601, the impact on the transverse sleeve 5 is minimized to avoid accidental deformation of the transverse sleeve due to excessive vibration.

[0025] In summary: for the pouring process of the concrete base platform used in electric boilers, the construction operation method is optimized based on conventional grouting equipment and oscillators, which is based on layered pouring. However, for the application requirements in electric boilers, the first is to bury the transverse sleeve. On the one hand, it can serve as a heat dissipation channel during operation and during the solidification of concrete. Secondly, in order to improve the structural strength of the overall concrete structure, the transverse sleeve is internally supported and reinforced, and then a pressure arc plate is added to change the stress and deformation degree of the transverse sleeve. In the later stage of pouring, the compaction between the concrete is further improved by inserting the sleeve cone. Secondly, it can also serve as a cooling structure during operation. After the concrete is completely solidified, it not only ensures the structural strength of the base platform during the operation of the electric boiler, but also meets the anti-deformation ability and heat dissipation ability during the alternating load period.
