Description

Technical Field

[0001] The present invention relates to the technical field of nuclear power plant construction, in particular to an experimental method for pouring concrete for a steam generator compartment and an experimental mold thereof. Background Art

[0002] The nuclear island steam generator (SNSG) is a key component of a nuclear power plant's steam supply system. Located within the nuclear island, its primary function is to transfer heat generated by the reactor to the secondary water supply, heating it and generating steam. Currently, the construction of a SNSG compartment is typically accomplished by installing a SNSG compartment within the nuclear island and pouring concrete into it to form the SNSG compartment structure. Due to the SNSG compartment's large size, a large amount of concrete must be poured into the SNSG compartment to form the SNSG compartment. This large amount of concrete generates significant heat of hydration, which compresses the SNSG compartment, causing irreversible deformation. To prevent this irreversible deformation, the SNSG compartment must be poured in multiple layers, with a waiting period between each pour. Furthermore, to better control mold deformation, the height of each concrete pour and the waiting time between pours must be determined. However, these requirements are currently unavailable. Summary of the Invention

[0003] The main purpose of the present invention is to propose an experimental method and an experimental mold for pouring concrete in a steam generator compartment, aiming to solve the technical problem of being unable to determine the pouring height of each concrete pouring into the mold and the waiting time between two adjacent concrete pourings.

[0004] To achieve the above-mentioned purpose, the present invention proposes an experimental method for pouring concrete in a steam generator compartment, which includes:

[0005] An experimental mold is provided; wherein the experimental mold includes a curved wall and a flat wall, a first casting cavity is formed in the curved wall, a second casting cavity is formed in the flat wall, the curved wall and the flat wall are arranged at an angle, and the first casting cavity is connected to the second casting cavity;

[0011] If the first strain information or the second strain information is not within the strain threshold, the preset height and the preset time do not meet the requirements.

[0012] In one embodiment, the first strain monitoring assembly includes a plurality of first strain sensors, and the second strain monitoring assembly includes a plurality of second strain sensors;

[0013] The steps of installing a first strain monitoring assembly on the first inner cavity wall of the first casting cavity and installing a second strain monitoring assembly on the second inner cavity wall of the second casting cavity include:

[0014] A plurality of first strain sensors are installed on the first inner cavity wall at intervals along the vertical direction, and a plurality of second strain sensors are installed on the second inner cavity wall of the second casting cavity at intervals along the vertical direction.

[0015] In one embodiment, the length direction of the curved wall is a first direction, and two first monitoring areas are formed at both ends of the first casting cavity along the first direction; the length direction of the planar wall is a second direction, and two second monitoring areas are formed at both ends of the second casting cavity along the second direction;

[0016] The steps of installing a first strain monitoring assembly on the first inner cavity wall of the first casting cavity and installing a second strain monitoring assembly on the second inner cavity wall of the second casting cavity include:

[0017] Two first strain monitoring components are respectively installed at positions of the first inner cavity wall corresponding to the two first monitoring areas, and two first strain monitoring components are respectively installed at positions of the first inner cavity wall corresponding to the two first monitoring areas.

[0018] The present invention also proposes an experimental mold for pouring concrete in a steam generator compartment, which is used in the experimental method for pouring concrete in a steam generator compartment as described above; wherein, a pouring port for pouring concrete is provided at the top of the connection between the plane wall and the curved wall, and the pouring port is connected to the first pouring cavity and the second pouring cavity.

[0019] In one embodiment, a plurality of spaced apart inclined steps are formed on the curved wall, each of the inclined steps protrudes toward a side away from the first casting cavity to form an inclined surface, and a plurality of spaced apart straight steps are provided on the plane wall.

[0020] In one embodiment, the straight steps include a plurality of first steps and a plurality of second steps, each of the first steps protrudes outward along the length direction of the planar wall, and the protrusion lengths of each first step are different, and each of the second steps protrudes outward along the width direction of the planar wall, and the protrusion lengths of each second step are different.

[0021] In one embodiment, a plurality of first steps are spaced apart along the height direction of the plane wall, and the protrusion lengths of the spaced apart first steps decrease from top to bottom to form an inverted step shape.

A preset concrete pouring height and a preset waiting time are pre-set. Concrete is poured to the preset height into the experimental mold, and then the preset waiting time is waited. During the pouring and waiting process, the first strain information of the first inner wall is obtained in real time by the first strain monitoring assembly, and the second strain information of the second inner wall is obtained in real time by the second strain monitoring assembly. After waiting for the preset time, the first and second strain information are compared with the strain threshold of the experimental mold. If both the first and second strain information are within the strain threshold, then the deformation of the experimental mold meets the requirements for concrete pouring at the preset time and height, and no irreversible deformation occurs. Furthermore, since the experimental mold simulates a steam generator compartment, it can be determined that the preset time and height meet the requirements for concrete pouring in the steam generator compartment. In other words, it can be determined that the preset time and height are used for concrete pouring in the steam generator compartment. Conversely, if either the first or second strain information is not within the strain threshold, it can be determined that the preset time and height cannot be used for concrete pouring in the steam generator compartment.

[0037] The invention provides an experimental method for pouring concrete of a steam generator compartment.

[0038] See also Figures 1 to 4 In one embodiment of the present invention, the experimental method for pouring concrete for the steam generator compartment includes:

[0039] Step S100: providing an experimental mold; wherein the experimental mold includes a curved wall 10 and a flat wall 20, wherein a first casting cavity 11 is formed in the curved wall 10, and a second casting cavity 21 is formed in the flat wall 20; the curved wall 10 and the flat wall 20 are arranged at an angle, and the first casting cavity 11 is connected to the second casting cavity 21;

[0040] Step S200: installing a first strain monitoring assembly on a first inner cavity wall of the first casting cavity, and installing a second strain monitoring assembly on a second inner cavity wall of the second casting cavity;

[0041] Step S300: pouring concrete of a preset height into both the first pouring cavity and the second pouring cavity;

[0042] Step S400, waiting for a preset time, and obtaining strain information of the first inner cavity wall within the preset time through each of the strain monitoring components, and obtaining second strain information of the second inner cavity wall within the preset time through each of the second strain monitoring components;

[0043] Step S500: comparing the first strain information and the second strain information with a strain threshold;

[0044] Step S510: If both the first strain information and the second strain information are within the strain threshold, the preset height and the preset time meet the requirements;

[0045] Step S520: If the first strain information or the second strain information is not within the strain threshold, the preset height and the preset time do not meet the requirements.

[0046] The technical solution of the present invention provides an experimental mold, which includes a curved wall 10 and a flat wall 20. A first casting cavity 11 is formed in the curved wall 10, and a second casting cavity 21 is formed in the flat wall 20. The experimental mold with the curved wall 10 and the flat wall 20 can simulate the curved section and the flat section of the steam generator compartment. By installing a first strain monitoring component on the first inner cavity wall of the first casting cavity 11 and installing a second strain monitoring component on the second inner cavity wall of the second casting cavity 21, the first strain information of the first inner cavity wall and the first strain information of the second inner cavity wall can be obtained respectively through the first strain monitoring component and the second strain monitoring component. The first strain information and the second strain information can be used to determine the degree of deformation of the flat wall 20 and the curved wall 10 of the experimental mold, thereby determining the degree of deformation of the experimental mold. A preset height for concrete pouring and a preset waiting time between concrete pours are pre-set. Concrete is poured to the preset height in the experimental mold, and the preset time is waited. During the pouring and waiting process, first strain information of the first inner cavity wall is acquired in real time via the first strain monitoring component, and second strain information of the second inner cavity wall is acquired in real time via the second strain monitoring component. After the preset waiting time, the first and second strain information are compared with the strain threshold of the experimental mold. If both the first and second strain information are within the strain threshold, the deformation of the experimental mold meets the requirements for concrete pouring at the preset time and height, and no irreversible deformation occurs. Furthermore, since the experimental mold simulates a steam generator compartment, it can be determined that the preset time and height meet the requirements for concrete pouring in the steam generator compartment. That is, the preset time and height can be used to pour concrete in the steam generator compartment. Conversely, if either the first or second strain information is not within the strain threshold, it can be determined that the preset time and height cannot be used to pour concrete in the steam generator compartment.

[0047] Furthermore, the first strain information is the first strain value of the first inner cavity wall at each time point during the waiting time, and the second strain information is the second strain value of the second inner cavity wall at each time point during the waiting time. If both the first strain information and the second strain information are within the strain threshold, then all first strain values ​​and all second strain values ​​obtained during the waiting time are within the strain threshold. If both the first strain information or the second strain information are within the strain threshold, then any first strain value or any second strain value obtained during the waiting time is within the strain threshold.

[0048] In one embodiment, the first strain monitoring assembly includes a plurality of first strain sensors 40 , and the second strain monitoring assembly includes a plurality of second strain sensors 50 ;

[0049] Step S200 includes:

[0050] Step S210 : installing a plurality of first strain sensors at intervals along the vertical direction on the first inner cavity wall, and installing a plurality of second strain sensors at intervals along the vertical direction on the second inner cavity wall of the second casting cavity.

[0051] Vertical Figure 2 The up and down directions in .

[0052] Specifically, as shown in the figure, a plurality of first strain sensors 40 are arranged at intervals along the upper and lower directions of the first inner cavity wall, and a plurality of second strain sensors 50 are arranged at intervals along the upper and lower directions of the second inner cavity wall. Through the plurality of first strain sensors 40 and the plurality of second strain sensors 50, the first inner cavity wall and the second inner cavity wall can be monitored more accurately and the monitoring is more comprehensive.

[0053] In one embodiment, the length direction of the curved wall 10 is a first direction, and two first monitoring areas are formed at both ends of the first casting cavity 11 along the first direction. The length direction of the planar wall 20 is a second direction, and two second monitoring areas are formed at both ends of the second casting cavity 21 along the second direction.

[0054] Step S200 includes:

[0055] Step A210: Install two first strain monitoring components at positions of the first inner cavity wall corresponding to the two first monitoring areas, and install two first strain monitoring components at positions of the first inner cavity wall corresponding to the two first monitoring areas.

[0056] Specifically, if Figures 2 to 4 As shown, the first direction is Figure 2 The front-to-back direction in the second direction is Figure 2 In the left and right directions, the first casting cavity 11 is respectively formed with two first monitoring areas along the length direction of the curved wall 10, and the second casting cavity 21 is respectively formed with two second monitoring areas along the length direction of the plane wall 20. By respectively arranging two first strain monitoring components in the two first monitoring areas, the two ends of the first inner cavity wall along the length direction of the curved wall 10 can be monitored, and by respectively arranging two second strain monitoring components in the two second monitoring areas, the two ends of the second inner cavity wall along the length direction of the plane wall 20 can be monitored, and the monitoring is more comprehensive.

[0057] The present invention also provides a test mold for pouring concrete in a steam generator compartment. This test mold is used in the test method for pouring concrete in a steam generator compartment described above. The specific steps of this test method are similar to those of the aforementioned embodiments. Since this test mold for pouring concrete in a steam generator compartment utilizes all the technical solutions of all the aforementioned embodiments, it at least possesses all the beneficial effects brought about by the technical solutions of the aforementioned embodiments, which will not be detailed here. A pouring port 30 for pouring concrete is provided at the top of the junction between the planar wall 20 and the curved wall 10. The pouring port 30 communicates with the first pouring cavity 11 and the second pouring cavity 21.

[0058] Specifically, if Figure 2 As shown, a pouring port 30 for pouring concrete is provided at the top of the connection between the plane wall 20 and the curved wall 10. Concrete can be poured into the first pouring cavity 11 and the second pouring cavity 21 through the pouring port 30, and pouring is simple and convenient.

[0059] In one embodiment, a plurality of spaced apart inclined steps 12 are formed on the curved wall 10 , each inclined step 12 protrudes toward a side away from the first casting cavity 11 to form an inclined surface, and a plurality of spaced apart straight steps 22 are provided on the plane wall 20 .

[0060] Specifically, if Figure 2 As shown, by providing a plurality of inclined steps 12 on the curved wall 10 to simulate the effect of an inclined structure on the steam generator compartment, and providing a plurality of straight steps 22 on the plane wall 20 to simulate the effect of structures of different cross-sectional sizes on the steam generator compartment, the curved wall 10, the plane wall 20 and the inclined steps 12 and straight steps 22 thereon are used to simulate various structures on the steam generator compartment. As a result, the experimental mold proposed in the present invention integrates a variety of complex structures of different shapes and sizes, which better fits the complex geometric shape of the steam generator compartment. As a result, the experimental results of the concrete pouring of the steam generator compartment are closer to the actual working conditions of the steam generator compartment, thereby improving the accuracy of the experimental results.

[0061] In one embodiment, the straight steps 22 include a plurality of first steps 221 and a plurality of second steps 222. Each first step 221 protrudes outward along the length direction of the planar wall 20, and the protruding lengths of each first step 221 are different. Each second step 222 protrudes outward along the width direction of the planar wall 20, and the protruding lengths of each second step 222 are different.

[0062] See also Figure 2 , Figure 2 The left and right directions in the figure are the length directions of the plane wall 20. Figure 2The front-to-back direction in the figure is the width direction of the planar wall 20. Each first step 221 protrudes outward along the length of the planar wall 20, and the protrusion lengths of each first step 221 vary. Thus, each first step 221 simulates the mechanical properties of structures of different lengths in the steam generator compartment. Each second step 222 protrudes outward along the width of the planar wall 20, and the protrusion lengths of each second step 222 vary. Thus, each second step 222 simulates the mechanical properties of structures of different widths in the steam generator compartment. By combining multiple first steps 221 and multiple second steps 222, a variety of combined structures of different lengths and widths can be formed, facilitating the simulation of various complex geometric shapes of different lengths and widths, more accurately simulating the complexity and irregularities of actual structures, and improving the accuracy of the experiment.

[0063] In one embodiment, the plurality of first steps 221 are spaced apart along the height direction of the plane wall 20 , and the protrusion lengths of the plurality of spaced apart first steps 221 decrease from top to bottom to form an inverted step shape.

[0064] Furthermore, if Figure 2 and Figure 3 As shown, multiple first steps 221 are in the shape of inverted steps, that is, the protrusion length of the first step 221 located at the top is the longest, and the protrusion length of the first step 221 located at the bottom is the shortest, so that each first step 221 is cantilevered relative to the first step 221 below it, thereby facilitating the simulation of protrusions of different lengths in the steam generator compartment.

[0065] In one embodiment, the plurality of inclined steps 12 are spaced apart along the height direction of the curved wall 10 , and the protruding lengths of the plurality of inclined steps 12 are different, and the inclination angles of the inclined surfaces are different.

[0066] Specifically, if Figure 2 and Figure 3 As shown, each inclined step 12 protrudes outward and forms a ridge extending along the height of the curved wall 10, forming two inclined surfaces on either side of the ridge of the inclined step 12. The protrusion length of the ridge relative to the curved wall 10 varies, and the inclination angles of each inclined surface vary. This allows the multiple inclined steps 12 to simulate inclined structures with a variety of different inclination angles. It should be noted that each inclined surface can be either straight or curved, and the specific arrangement of each inclined surface depends on the actual structure of the steam generator compartment to be simulated.

[0067] In one embodiment, a plurality of embedded parts 23 of different sizes are spaced apart on the curved wall 10 or the plane wall 20 .

[0068] It should be noted that by providing embedded parts 23 of different sizes, the situation of embedded parts 23 on the steam generator compartment can be simulated, thereby further improving the accuracy of the experimental results.

[0069] In one embodiment, a hole 24 is formed on the planar wall 20 , and the hole 24 runs through the width direction of the planar wall 20 .

[0070] It can be understood that the hole 24 is located in the middle of the plane wall 20 and penetrates the plane wall 20 along the width direction. By providing the hole 24, the situation where a steam generator compartment has an opening can be simulated, further improving the accuracy of the experimental results.

[0071] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention.
