Description

TECHNICAL FIELD

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

[0002] For the work of electric boiler laying facilities, the pouring and forming process of the concrete base is the most basic and critical step. First, the surface flatness deviation should be less than or equal to 5mm, the verticality deviation should be less than or equal to H / 1000 and less than or equal to 30mm, and considering the difficulty of the work, the method of precast concrete is not used, but the method of on-site integrated pouring and forming is used.

[0003] From the operation characteristics of the electric boiler, the operation process is affected by factors such as operating temperature, operating load and operating vibration, which affects the concrete base. In this regard, the concrete also needs to meet the sufficient volume and firmness to bear the weight and operating load of the electric boiler, and has two key characteristics of vibration protection and thermal stress deformation protection;

[0004] Specifically, the concrete pouring process is described in the related content of CN118814569A and CN113146835A. The essence is to improve the compactness of the concrete slurry by using a vibrating rod to reduce the amount of air bubbles. In order to meet the requirement of thermal stress deformation protection, a pre-embedded pipeline (as a heat dissipation channel) is mostly used. However, the pipeline is difficult to provide stable support force, and even during the operation period, the stress generated during the solidification of the concrete, the load or operating vibration of the electric boiler equipment causes the pipeline to deform, directly affecting the structural stability of the overall concrete base. If the heat dissipation method is not used, the internal temperature of the concrete base is difficult to dissipate in time, and in addition, the process of concrete solidification is an exothermic process. If the temperature dissipation effect is not good, the internal temperature rising gradient will also cause the concrete base to crack. Therefore, this application proposes a solution. SUMMARY

[0005] The purpose of the present application is to provide a large-volume concrete pouring method and pouring device. For the concrete base applied in the electric boiler, it must meet the sufficient volume and firmness to meet the weight and operating load of the electric boiler equipment, and further meet the vibration prevention and control and thermal stress deformation protection. However, in the actual construction process, a single vibration method cannot meet the construction requirements, and there may be problems of unstable structure or poor heat dissipation effect.

[0006] The purpose of the present application can be achieved by the following technical solution: a large-volume concrete pouring method using a concrete grouting group and an oscillator, applied in the pouring process of the concrete platform base of the electric boiler, including four processes of frame erection, initial pouring, post-pouring and reinforcement finishing in sequence, and including the following contents:

[0007] Frame building: according to the installation position of the electric boiler, the base frame is laid out, and the heat dissipation pipe group is welded in the base frame along the length direction of the base frame;

[0008] Initial pouring process: the base frame is filled with concrete slurry by the concrete grouting group, and an initial filling area is formed in the base frame, and the upper side of the base frame corresponding to the initial filling area forms a blank 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;

[0009] Post-pouring process: the initial filling area is vibrated and densified by the oscillator during the initial pouring process to enter the initial setting stage, and after the initial setting stage is completed, the blank area in the initial pouring process is filled with concrete slurry by the concrete grouting group and simultaneously vibrated and densified to form a post-filling area, and the surface of the post-filling area is flush with the upper surface of the base frame;

[0010] Reinforcement and finishing: after the post-pouring process is completed, the upper end cap is covered on the base frame, and the insert sleeve cone is inserted into the post-filling area and the initial filling area along the vertical direction through the upper end cap, and the upper end cap is removed, and the internal water cooling circulation action is performed through one or more heat dissipation pipe groups, which vibrates and densifies the initial filling area through the oscillator and the other heat dissipation pipe groups, and levels the surface of the post-filling area.

[0011] The application also provides a large-volume concrete pouring device applied in the large-volume concrete pouring method.

[0012] Further, the linear distance between the center point of the transverse sleeve and the bottom surface of the base frame is greater than one-half of the height of the base frame.

[0013] Further, the transverse sleeve extends to the outside of the base frame at both ends and is provided with a sleeve cap through a threaded connection, and the sleeve cap is provided with a water inlet and a fixing port.

[0014] Further, the lower end of the insert sleeve cone is conical and hollow, and the length of the insert sleeve cone is greater than two-thirds of the height of the base frame, and the upper end cap is provided with a mounting port corresponding to the insert sleeve cone.

[0015] Further, the transverse sleeve is provided with a pressure receiving sleeve group along the length direction in a linear and equidistant manner, and the pressure receiving sleeve group is composed of a sleeve ring and two pressure receiving arc plates, the sleeve ring is welded on the transverse sleeve, and the pressure receiving arc plates are welded on the upper and lower sides of the sleeve ring in the vertical direction.

[0016] Further arrangement is that the lateral cross section of the pressure-accepted arc plate is curved and arched along the direction close to the lateral sleeve.

[0017] Further arrangement is that a reinforcing plug is arranged in the lateral sleeve through the fixing opening, the outer wall of the reinforcing plug is matched with the inner wall of the lateral sleeve, and a water groove is arranged between the reinforcing plug and the inner wall of the lateral sleeve.

[0018] The present application has the following advantages:

[0019] 1. Based on the conventional layered pouring method of concrete, and particularly aiming at the use requirements of the concrete base platform of the electric boiler, firstly, the overall platform structure has better structural strength, and the key lies in the lateral sleeve embedded during pouring. The lateral sleeve is mainly used to meet the heat dissipation channel during the operation of the electric boiler. After the concrete slurry is completely solidified, the lateral sleeve forms an integral structure. In order to ensure the structural strength of the base platform, a reinforcing plug can also be inserted into the lateral sleeve to avoid the risk of cracking of the lateral sleeve due to uneven stress distribution under the load of the electric boiler operation.

[0020] 2. The overall pouring process is further described as follows: firstly, the layered pouring method ensures that the lateral sleeve is completely immersed in the concrete layer. For this, the lateral sleeve is further provided with a pressure-accepted sleeve group, and the pressure-accepted sleeve group is completely immersed in the concrete layer. The key lies in the pressure-accepted arc plates on the upper and lower sides. The pressure-accepted arc plates are "force transfer" structures for the lateral sleeve to bear the load of the electric boiler operation. On the basis of supporting the reinforcing plug, the stress generated by the load of the electric boiler operation can also be dispersed to improve the anti-vibration structural strength of the overall concrete base platform.

[0021] 3. The lateral sleeve is further described as follows: the lateral sleeve not only serves as a heat dissipation channel, but also can serve as a water cooling channel and an oscillation channel during the solidification of the concrete. During the solidification of the concrete, the temperature gradient inside the concrete layer can be reduced by injecting into the lateral sleeve, and the oscillation rod in the oscillator can be directly inserted into the lateral sleeve, so as to continuously and indirectly vibrate the concrete during solidification to expel bubbles and play a reinforcing role.

[0031] The technical solutions of the application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the application.

[0032] Embodiment one: for the concrete base applied in the electric boiler, it is necessary to meet the weight and operation load of the electric boiler equipment by meeting the sufficient volume and firmness, and further meet the vibration prevention and protection against thermal stress deformation, but in the actual construction process, a single vibration method is difficult to meet the construction requirements, and there may be problems of unstable structure or poor heat dissipation effect. For this, the following technical solution is proposed:

[0033] With reference to Figures 1-7 , the mass concrete pouring method in the embodiment uses a concrete grouting group and a vibrator, and is applied in the pouring process of the concrete platform base of the electric boiler. The method includes four processes of frame erection, initial pouring, post-pouring and reinforcement finishing in sequence, and includes the following contents:

[0034] ​​​Frame building: according to the installation position of the electric boiler, the base frame is laid out, and the heat dissipation pipe group is welded in the base frame along the length direction of the base frame;

[0035] Initial pouring process: the base frame is filled with concrete slurry by the concrete grouting group, and the initial filling area is formed in the base frame, and the 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;

[0036] Post-pouring process: the initial filling area is vibrated and densified by the oscillator in the initial pouring process to enter the initial setting stage, and after the initial setting stage is completed, the blank area in the initial pouring process is filled with concrete slurry by the concrete grouting group and vibrated and densified synchronously to form the post-filling area, and the surface of the post-filling area is flush with the upper surface of the base frame;

[0037] Reinforcement and finishing: after the post-pouring process is completed, the upper end cap is covered on the base frame, and the insert sleeve cone is inserted into the post-filling area and the initial filling area along the vertical direction through the upper end cap, and the upper end cap is removed, and the internal water cooling circulation is performed through one or more heat dissipation pipe groups, which vibrates and densifies the initial filling area through the oscillator and the other heat dissipation pipe groups, and levels the surface of the post-filling area.

[0038] Among them, a large volume of concrete pouring device is applied in the large volume of concrete pouring method, which includes a base frame 1, a transverse sleeve 5, and an upper end cap 3, the transverse sleeve 5 is inserted in the base frame 1 along the length direction parallel to the base frame 1, and the transverse sleeve 5 is linearly equidistantly arranged along the width direction of the base frame 1.

[0039] Basic principle: the pouring process of the concrete platform is simply explained: its essence is to inject a certain amount of concrete slurry, and then to vibrate the concrete slurry with a vibrator to remove bubbles and to densify, but the present application mainly aims at the pouring process of the concrete base platform of the electric boiler, firstly, for the operation process of the electric boiler, on the one hand, the load and vibration problem during operation is set, and secondly, the high temperature problem during operation of the electric boiler, if the pouring is carried out in a conventional way, firstly, the high temperature problem directly affects the concrete base platform, and the local cracking problem may occur, especially in the case of high load and vibration problem aggravating the local cracking problem;

[0040] Therefore, the present application optimizes a pouring method in this way, firstly, according to the installation position of the electric boiler, the base frame 1 is erected, and the heat dissipation pipe group is welded in the base frame along the length direction of the base frame; Figure 2For example, the essence of the base frame 1 is three or more support plates combined to form a complete closed loop area, and each support plate is directly fixed to the ground by bolting, and the inside of the base frame 1 is used as the pouring area of the concrete slurry, but the difference from the conventional method is that: the transverse sleeve 5 needs to be welded according to the length direction of the base frame 1, the transverse sleeve 5 is used as a heat dissipation pipe group, and a plurality of pressure receiving sleeves 6 are further welded on the transverse sleeve 5, and the transverse sleeve 5 needs to be open at both ends and extend to the outside of the base frame 1.

[0041] As for the use process of the concrete grouting group and the oscillator, it is not described in detail in the present application, but it needs to be explained that: when the concrete slurry is injected into the inside of the base frame 1 through the concrete grouting group, the liquid level of the concrete slurry must be greater than two-thirds of the height of the base frame, referring to Figure 3 , only the initial filling area completely wrapping the transverse sleeve 5 is formed, and the next pouring is carried out after the initial filling area of the concrete slurry is completed, so that the overall concrete slurry liquid level is completely parallel to the base frame.

[0042] Example two: based on example one, the two pouring processes are as follows:

[0043] The linear distance between the center point of the transverse sleeve 5 and the bottom surface of the base frame 1 is greater than one-half of the height of the base frame 1, the transverse sleeve 5 extends to the outside of the base frame 1 at both ends and is provided with a sleeve cap 2 through threaded connection, the sleeve cap 2 is provided with a water inlet 202 and a fixing port 201, the lower end of the plug-in sleeve cone 4 is conical and hollow, and the length of the plug-in sleeve 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-in sleeve cone 4, the transverse sleeve 5 is provided with a pressure receiving sleeve group 6 at a linear distance along the length direction, the pressure receiving sleeve group 6 is composed of a sleeve ring 602 and two pressure receiving arc plates 601, the sleeve ring 602 is welded on the transverse sleeve 5, and the pressure receiving arc plates 601 are welded on the upper and lower sides of the sleeve ring 602 along the vertical direction, the lateral cross section of the pressure receiving arc plate 601 is curved and arched in the direction close to the transverse sleeve 5, the transverse sleeve 5 is provided with a reinforcing stopper 7 through the fixing port 201, the outer wall of the reinforcing stopper 7 matches the inner wall of the transverse sleeve 5, and a water groove 501 is arranged between the reinforcing stopper 7 and the inner wall of the transverse sleeve 5, the fixing port 201 is mainly used for fixing the reinforcing stopper 7, and vice versa, the water inlet 202 is mainly used as the water inlet structure when the low-temperature water or normal-temperature water is pumped into the transverse sleeve 5.

[0044] Scheme description: the purpose of ensuring that the liquid level of the concrete slurry must be greater than two-thirds of the height of the base frame 1 in the initial pouring process is to ensure that the concrete slurry completely wraps the pressure receiving sleeve group 6, referring to Figure 6Because of the structural limitations of the pressure arc plate 601, it is necessary to ensure that the concrete slurry is completely filled in the lower part of the pressure arc plate 601 with the assistance of the vibrator, so as to avoid the problem of insufficient amount in the overall initial filling area.

[0045] The subsequent pouring process takes place after the initial setting of the initial filling zone. It should be noted that the initial setting stage, as described in this invention, primarily completes the preliminary shaping of the initial filling zone, but does not imply that the initial filling zone exhibits solidification issues. The initial setting stage also includes the following actions:

[0046] Action 1: Perform internal water cooling circulation on one or more transverse sleeves 5. In this stage, the transverse sleeves 5 are represented as heat dissipation pipe groups in the casting method. The internal water cooling circulation avoids significant temperature differences in the initial filling area. The temperature of the liquid injected into the transverse sleeves 5 during the internal water cooling circulation is controlled according to the temperature range during concrete solidification, thus representing an internal heat dissipation channel.

[0047] Action 2: During the initial pouring process, the concrete slurry is directly contacted by structures such as the vibrating rod in the vibrator. In the initial setting stage, the vibrating rod can also be inserted into the transverse sleeve 5. In addition to water cooling, the concrete slurry in the initial filling area can be indirectly vibrated through indirect contact. It can also be vibrated synchronously with the initial filling area to further improve the compactness of the concrete slurry.

[0048] The post-pouring process is merely a... Figure 3 The blank areas are filled in, and this process also requires vibration treatment using a vibrator. It is important to note that after the blank areas are poured, the upper cap 3 is directly placed on the overall base frame 1, thus forming a relatively closed area inside the overall base frame 1. During this process, the insert cone 4 is inserted into the upper cap 3 in a completely vertical direction. It should be noted that because the base frame 1 is already completely filled with concrete grout, the process of inserting the insert cone 4 causes the internal volume of the base frame 1 to be "shrunken," thus compressing the filled concrete grout. This further improves the compactness of the concrete grout. After maintaining this for a period of time, once the concrete grout in both the post-filling area and the initial filling area has entered the solidification state, the upper cap 3 is removed, and the surface is leveled.

[0049] Finally, wait for the complete curing process of the concrete slurry, and during the waiting for complete curing, the above-mentioned internal water cooling circulation action and vibration densification action can be performed synchronously, and both do not need to be performed continuously, and the working time thereof can be set, for example, after the internal water cooling circulation action and vibration densification action are performed for 2h, the vibration rod is extracted to stop pumping water into the transverse sleeve 5, and the reinforcing plug rod 7 is inserted into each transverse sleeve 5 to avoid deformation of the transverse sleeve 5 when the concrete slurry is completely cured;

[0050] And the reinforcing plug rod 7 is explained: 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 flow, a water groove 501 matching the length of the transverse sleeve 5 is formed on the outer surface of the reinforcing plug rod 7. For this, the heat dissipation process is explained: during the pouring process or subsequent use process, the reinforcing plug rod 7 is inserted into the transverse sleeve 5, which provides external support force to the inside of the transverse sleeve 5, but because the water groove 501 is provided on the outer wall of the reinforcing plug rod 7, the reinforcing plug rod 7 has a water flow channel inside, so that low-temperature water or normal-temperature water is injected at one end of the transverse sleeve 5. The water body can flow through the water groove 501 and undergo an indirect heat exchange process with the concrete.

[0051] Example three: based on example two, the operation of the formed concrete base platform during the operation is explained:

[0052] In combination with example two, after the entire concrete slurry is completely cured, the base frame 1 does not need to be removed, after the electric boiler is installed on the cured concrete base platform, and during the operation of the electric boiler, on the one hand, static normal-temperature water can be injected into each plug sleeve cone 4, and on the other hand, normal-temperature water is continuously pumped into the transverse sleeve 5. The normal-temperature water flows at a slow speed to maintain the temperature difference inside the concrete base platform with normal-temperature water. Referring to Figure 6 During the operation of the electric boiler, the stressed arc plate 601 will be subjected to stress generated by the vibration of the electric boiler, but the stressed arc plate 601 has a structural characteristic, which can be directly understood as the transverse sleeve being subjected to upward and downward stress, respectively, and the two are balanced and offset. Specifically, the stressed arc plate 601 is used as a force-bearing internal structure, so that Figure 6For example, when the upper position of the pressure arc plate 601 bears the concrete, because of the structural characteristics of the upper position of the pressure arc plate 601, it can be understood that the direct downward pressure is generated on the transverse sleeve 5, but because of the structural characteristics of the lower position of the pressure arc plate 601, the downward pressure transmitted to the transverse sleeve 5 is transferred to the lower position of the pressure arc plate 601, so that the stress generated by the concrete on 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, but through the transmission process of the two pressure arc plates 601, the influence on the transverse sleeve 5 is minimized, and the accidental deformation process of the transverse sleeve caused by excessive vibration is avoided.

[0053] As shown above: for the pouring process applied to the concrete base platform of the electric boiler, the construction operation mode is optimized based on the conventional grouting equipment and oscillator, which is based on layered pouring, but for the application requirements in the electric boiler, first, the transverse sleeve is embedded, which can be used as a heat dissipation channel during operation and during concrete solidification, second, to improve the structural strength of the overall concrete structure, the transverse sleeve is internally supported and reinforced, then the pressure arc plate is added to change the stress deformation degree of the transverse sleeve, and in the later pouring stage, the sleeve cone is further added to improve the tightness between the concrete, which can also be used as a cooling structure during operation, after the concrete is completely solidified, it can not only ensure the structural strength of the base platform during the operation of the electric boiler, but also meet the anti-deformation and heat dissipation capacity during the alternating load.
