Description

Technical Field

[0001] This invention belongs to the field of nuclear power plant construction technology, and relates to a construction positioning measurement and detection method, and more particularly to a construction positioning measurement and detection method for containment building machines. Background Technology

[0002] With the development of the national economy, the demand for energy is increasing, providing ample room for the development and scale of nuclear power construction in my country. When a nuclear power plant reactor accident occurs, it releases large amounts of radioactive material. The containment vessel, as the last line of nuclear safety, prevents the spread of radioactive material and contamination of the surrounding environment. It also often serves as the enclosure structure of the reactor building, protecting the reactor equipment and systems from adverse external influences. It is a large, specialized container structure. Containment vessel construction is located on the critical path and affects the main construction period. Automated construction technology, proven in domestic and international nuclear power construction practices, is an effective way to reduce on-site construction work, lower safety hazards, shorten construction time, and reduce project costs. It is also one of the effective measures in my country to address the contradiction between safe, efficient, and large-scale nuclear power construction and resource shortages, as well as quality and safety. Currently, containment vessel construction often uses automated construction machines. Because these machines require safety protection, including climbing supports and protective grids, surveying work loses its line-of-sight, posing new technical challenges. Summary of the Invention

[0003] This invention provides a method for construction positioning measurement and detection of a containment building machine to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, the present invention provides a method for positioning, measuring, and detecting a containment building machine, characterized by the following steps: S1, multiple reference points are laid out around the containment structure, each reference point being able to see one reference point in front of it and one reference point behind it; the multiple reference points are divided into first-class reference points and second-class reference points, which are alternately set; S2, before the building machine is installed, during the construction of the first-layer (the initial installation layer of the building machine is the first layer) outer shell concrete wall, a reference point support grid is installed at the top of the first-class reference points on the wall; the reference point support grid is higher than the second-layer outer shell concrete wall; a reference point movable component is installed on the top of the reference point support grid as the first-layer first-class reference point position; the coordinates of the first-layer first-class reference point position are obtained using known secondary grid points; S3, in the second-layer outer shell... During the construction of the concrete wall, a reference point support grid is installed at the second type of reference point on the top of the wall; the reference point support grid is higher than the third layer of the outer concrete wall; a reference point movable component is installed on the top of the reference point support grid as the second type of reference point position of the second layer; the coordinates of the second type of reference point position of the second layer are obtained using the exposed first type of reference point position of the first layer; S4, the azimuth axis and arc line positioning are performed based on the exposed first type of reference point position of the first layer and the second type of reference point position of the second layer; S5, S3~S4 are repeated until the azimuth axis and arc line positioning of the entire containment are completed. The first type of reference point position and the second type of reference point position are alternately buried layer by layer, and the coordinates of the second type of reference point position / first type of reference point position of the current layer are obtained based on the first type of reference point position / second type of reference point position obtained in the previous layer.

[0005] Furthermore, the present invention provides a method for construction positioning measurement and detection of a containment building machine, which may also have the following features: the installation method of the reference point support grid frame is as follows: first, the grid frame pre-embedded angle steel base is pre-embedded in the top of the wall, with a embedding depth of 500-700mm; after the concrete is poured and the strength reaches 60%, the grid frame is set on the pre-embedded angle steel base, and the bottom of the grid frame is fixed to the pre-embedded angle steel base.

[0006] Furthermore, this invention provides a method for positioning and measuring the construction of a containment building machine, which may also have the following feature: the method for obtaining the coordinates of the first type of reference point of the first layer using known secondary network points is as follows:

[0007] Mark the second type of reference point on the top of the first-layer outer concrete wall as the location of the second type of reference point for the first layer. Erect a tripod and prism or total station at the second type of reference point on the first layer. Simultaneously, erect prisms or total stations at the first type of reference point and related secondary network points on the first layer, and connect them with the secondary network points to measure the azimuth and side lengths. Calculate the coordinates of the first type of reference point on the first layer using the least squares method. Specifically, use the known secondary network points to measure the coordinates of the first type of reference point on the first layer, then use these coordinates to calculate the coordinates of the second type of reference point on the first layer. Then, use the obtained second type of reference point to extrapolate the coordinates of the first type of reference point on the first layer. Finally, use the least squares method to calculate the minimum threshold value for the first type of reference point on the first layer, which is the coordinate of the first type of reference point on the first layer.

[0008] Alternatively, a prism or total station can be set up at the first-class reference point and associated secondary network points in the first layer, and the coordinates of each first-class reference point in the first layer can be obtained by directly measuring the secondary network points in sequence.

[0009] Furthermore, the present invention provides a method for positioning and measuring a containment building machine, which may also have the following features: the method for obtaining the coordinates of the second type of reference point of the second layer using the exposed first type of reference point of the first layer is as follows: a prism or total station is set up at the first type of reference point of the first layer and the second type of reference point of the second layer to measure the azimuth angle and side length. The coordinates of the second type of reference point of the second layer are calculated by using the least squares method with the first type of reference point of the first layer as the reference. The specific method is as follows: Measure the coordinates of the second-class reference points in the second layer using the first-class reference points in the first layer. Then, calculate the coordinates of the first-class reference points in the first layer using the second-class reference points in the second layer. Next, use the obtained first-class reference points in the first layer to deduce the coordinates of the second-class reference points in the second layer. Calculate the minimum threshold using the least squares method with the coordinates of the second-class reference points in the second layer obtained from the first-class reference points in the first layer and the coordinates of the second-class reference points in the second layer deduced from the first-class reference points in the first layer. This threshold is the coordinate of the second-class reference points in the second layer.

[0010] Furthermore, the present invention provides a construction positioning measurement and detection method for a containment building machine, which may also have the following feature: wherein the reference point support grid frame of each layer is 1.2m higher than the outer shell concrete wall of the next layer.

[0011] Furthermore, the present invention provides a method for positioning and measuring a containment building machine, which may also have the following features: In step S4, the method for azimuth axis positioning is as follows: S4.1.1, setting up a total station at the first type of reference point of the exposed first layer or the second type of reference point of the second layer; S4.1.2, setting up a prism near the positioning point of the azimuth axis on the outside of the containment, leveling it, and measuring the coordinates (X1, Y1) of the positioning point; S4.1.3, calculating the azimuth deviation value T of the positioning point.

[0012] T=-(X1-X0)sinα+(Y1-Y0)cosα;

[0013] In the formula, (X0, Y0) are the center coordinates of the reactor building, and α is the azimuth angle of the positioning axis in the reactor building; S4.1.4, Adjust the positioning point in the opposite direction according to the azimuth deviation value T, remeasure the coordinates of the adjusted positioning point and calculate the azimuth deviation value T; S4.1.5, If the azimuth deviation value T of the adjusted positioning point coordinates meets the requirements, set the point marker; if the azimuth deviation value T of the adjusted positioning point coordinates does not meet the requirements, continue to adjust in the opposite direction until it meets the requirements; S4.1.6, Repeat S4.1.2 to 4.1.5 to determine the coordinates of the positioning point of the inner azimuth axis of the containment, and connect the positioning point of the outer azimuth axis of the containment and the positioning point of the inner azimuth axis of the containment to obtain the required azimuth axis.

[0014] Furthermore, the present invention provides a method for positioning measurement and detection during the construction of a containment building machine, which may also have the following feature: in S4.1.5 of the azimuth axis positioning method, when the azimuth deviation value T is less than 0.002m, the positioning point meets the requirements.

[0015] Furthermore, the present invention provides a method for positioning and measuring a containment building machine, which may also have the following features: In step S4, the method for locating the arc line is as follows: S4.2.1, setting up a total station at the first type of reference point of the exposed first layer or the second type of reference point of the second layer; S4.2.2, setting up a prism near the positioning point of the arc line, leveling it, and measuring the coordinates (X2, Y2) of the positioning point; S4.2.3, calculating the radius deviation value δR of the positioning point of the arc line.

[0016]

[0017] In the formula, (X0, Y0) are the coordinates of the reactor building center, and R is the design radius from the arc line to the reactor building center; S4.2.4, Adjust the positioning point in the opposite direction according to the radius deviation value δR, remeasure the coordinates of the adjusted positioning point and calculate the radius deviation value δR; S4.2.5, If the radius deviation value δR of the adjusted positioning point coordinates meets the requirements, set the point marker; if the radius deviation value δR of the adjusted positioning point coordinates does not meet the requirements, continue to adjust in the opposite direction until it meets the requirements; S4.2.6, Repeat S4.2.2 to 4.2.5, determine the coordinates of all positioning points of the arc line, and connect all positioning points of the arc line to obtain the required arc line.

[0018] Furthermore, the present invention provides a method for positioning measurement and detection during the construction of a containment building machine, which may also have the following feature: in S4.2.5 of the arc line positioning method, when the radius deviation value δR is less than 0.002m, the positioning point meets the requirements.

[0019] Furthermore, the present invention provides a construction positioning measurement and detection method for a containment building machine, which may also have the following features: wherein, in S5, during the construction of a certain layer of the outer shell concrete wall, the reference point movable components of the first type of reference point / second type of reference point of the interval layer are removed before the concrete is poured; during the construction of the outer shell concrete wall of this layer, a reference point support grid is installed at the first type of reference point / second type of reference point on the top of the wall.

[0020] The coordinates of the first type of reference point / the second type of reference point are obtained by dividing the first type of reference point by the second type of reference point.

[0021] Furthermore, the present invention provides a method for positioning and measuring the construction of a containment building machine, which may also have the following feature: at least eight reference points are set up around the containment.

[0022] The beneficial effects of this invention are as follows: This invention provides a method for positioning measurement and testing during the construction of a containment building machine, which can effectively ensure the accuracy of positioning measurement work, optimize the construction progress, and provide flexible setup. It solves the positioning problem of containment construction under closed conditions using a building machine, eliminates the need to dismantle the safety protection facilities of the building platform, helps to meet the needs of optimizing the construction progress, and effectively meets the quality requirements of on-site construction. Compared with the original testing method that requires the dismantling of safety protection facilities, it greatly improves construction efficiency. Specifically, the reference points can be cyclically deployed during the construction of the building crane, adapting to measurement and positioning work in enclosed structures. Measurement is convenient, and instruments can be set up according to the construction progress. Multiple sets can work simultaneously as needed to complete the entire installation and inspection process, ensuring measurement consistency. As the building crane ascends, the reference points are simultaneously raised, solving the positioning problem in the enclosed space of the containment structure. Construction control is carried out within the enclosed space without external communication, ensuring measurement control accuracy, construction quality, and construction progress. The movable reference point component has a simple structure and is easy to manufacture, consisting of supporting angle steel and a forced centering plate. It can be quickly installed and disassembled and is reusable. Measurement accuracy is high; using the forced centering plate, the instrument setup and alignment accuracy is improved from 1mm to 0.3mm. This invention's method has been tested in the field, demonstrating reliable quality, convenient and flexible construction, and high accuracy. Attached Figure Description

[0027] The specific embodiments of the present invention will be described below with reference to the accompanying drawings and specific examples.

[0028] A certain nuclear power plant has a double containment structure with an inner radius of R22.5m, an inner shell thickness of 1200mm, an outer shell thickness of 1500mm, a middle thickness of 1800mm, and a height of 55m. In order to improve the level of construction automation, a building-building machine is used for construction. The construction adopts an integral lifting platform and a fully enclosed enclosure, which makes the measurement work impossible to see. Now, the method of this invention is used for measurement control to ensure the positioning accuracy of each item in the containment, construction quality, and construction progress.

[0029] This invention provides a method for positioning and measuring the detection of a containment building machine during construction, comprising the following steps:

[0030] S1, such as Figure 1 As shown, eight reference points are arranged around the containment vessel, namely ZJ01, ZJ02, ZJ03, ZJ04, ZJ05, ZJ06, ZJ07, and ZJ08. Each reference point is visible to one reference point in front of it and one in front of it. The eight reference points are divided into Class I reference points and Class II reference points, which are alternated. That is, ZJ02, ZJ04, ZJ06, and ZJ08 are Class I reference points, and ZJ01, ZJ03, ZJ05, and ZJ07 are Class II reference points.

[0031] S2, such as Figure 2 As shown, before the building machine is installed, the first floor (the floor where the building machine is initially installed is the first floor, i.e.) Figure 2 During the construction of the outer concrete wall 1 (layer VII), reference point support grid 21 is installed at the top of the wall at ZJ02, ZJ04, ZJ06, and ZJ08. The structure of the reference point support grid 21 is as follows: Figure 3 As shown. The reference point supports the lattice frame 21 above the second-layer outer shell concrete wall.

[0032] The installation method for the benchmark-supported lattice frame is as follows: First, pre-embed angle steel bases for the lattice frame at the top of the wall, with a embedding depth of 600mm. The embedding depth refers to the depth of the bottom end of the pre-embedded angle steel base; the top of the pre-embedded angle steel base must be exposed. After the concrete has reached 70% strength, install the lattice frame on the pre-embedded angle steel base and weld the bottom of the lattice frame to the pre-embedded angle steel base for fixation.

[0033] A reference point movable component 22 is installed on the top of the reference point support lattice frame 21, serving as the ZJ02, ZJ04, ZJ06, and ZJ08 points of the first layer. For example... Figure 4 As shown, the reference point active component 22 includes a forced centering plate 221 and a support angle steel 222. The forced centering plate 221 is fixed to the top of the reference point support grid 21 by the support angle steel 222.

[0034] Using the known secondary network points SC01, SC02, SC03, SC09, SC08, and SC04, obtain the coordinates of the first-layer points ZJ02, ZJ04, ZJ06, and ZJ08. The specific method is as follows: Stainless steel plates are anchored at the top of the first-layer outer concrete wall at points ZJ01, ZJ03, ZJ05, and ZJ07. Cross points are marked on these plates to serve as the ZJ01, ZJ03, ZJ05, and ZJ07 points for the first layer. Tripods and prisms or total stations are then installed at these points. Simultaneously, prisms or total stations are installed at points ZJ02, ZJ04, ZJ06, and ZJ08 on the first layer, as well as at the associated secondary network points SC01, SC02, SC03, SC09, SC08, and SC04. These are then connected to the secondary network points SC01, SC02, SC03, SC09, SC08, and SC04 to measure the azimuth and side lengths. The coordinates of the ZJ02, ZJ04, ZJ06, and ZJ08 points on the first layer are calculated using the least squares method.

[0035] Specifically, using the known secondary network points SC01, SC02, SC03, SC09, SC08, and SC04, the coordinates of points ZJ02, ZJ04, ZJ06, and ZJ08 in the first layer are measured. Then, using the coordinates of points ZJ02, ZJ04, ZJ06, and ZJ08 in the first layer, the coordinates of points ZJ01, ZJ03, ZJ05, and ZJ07 in the first layer are calculated. Finally, using the obtained coordinates of points ZJ01, ZJ03, ZJ05, and ZJ07 in the first layer, the coordinates of... The coordinates of points ZJ02, ZJ04, ZJ06, and ZJ08 in the first layer are obtained by using the coordinates of points ZJ02, ZJ04, ZJ06, and ZJ08 in the first layer, measured using secondary network points, and the coordinates of points ZJ02, ZJ04, ZJ06, and ZJ08 in the first layer, which are then calculated using the least squares method. The minimum threshold is then calculated, which represents the coordinates of points ZJ02, ZJ04, ZJ06, and ZJ08 in the first layer. The calculation process and results are shown in the table below.

[0043] Alternatively, prisms or total stations can be set up at points ZJ02, ZJ04, ZJ06, and ZJ08 on the first layer, as well as the associated secondary network points SC01, SC02, SC03, SC09, SC08, and SC04, and the coordinates of each point ZJ02, ZJ04, ZJ06, and ZJ08 on the first layer can be directly measured sequentially using the secondary network points.

[0044] S3. Before constructing the second-layer outer concrete wall, remove the stainless steel marker plates ZJ01, ZJ03, ZJ05, and ZJ07. During the construction of the second-layer outer concrete wall, install a reference point support grid at the top of the wall at ZJ01, ZJ03, ZJ05, and ZJ07, using the same method as in S2. The reference point support grid should be higher than the third-layer outer concrete wall. Install movable reference point components at the top of the reference point support grid to serve as the ZJ01, ZJ03, ZJ05, and ZJ07 points for the second layer.

[0045] The coordinates of points ZJ01, ZJ03, ZJ05, and ZJ07 in the second layer are obtained using the exposed points ZJ02, ZJ04, ZJ06, and ZJ08 in the first layer. Specifically, a prism or total station is set up at points ZJ02, ZJ04, ZJ06, and ZJ08 in the first layer and points ZJ01, ZJ03, ZJ05, and ZJ07 in the second layer to measure the azimuth and side lengths. Using points ZJ02, ZJ04, ZJ06, and ZJ08 in the first layer as a reference, the coordinates of points ZJ01, ZJ03, ZJ05, and ZJ07 in the second layer are calculated using the least squares method.

[0046] Specifically: Using points ZJ02, ZJ04, ZJ06, and ZJ08 on the first layer, measure the coordinates of points ZJ01, ZJ03, ZJ05, and ZJ07 on the second layer. Then, using points ZJ01, ZJ03, ZJ05, and ZJ07 on the second layer, calculate the coordinates of points ZJ02, ZJ04, ZJ06, and ZJ08 on the first layer. Finally, using the obtained coordinates of points ZJ02, ZJ04, ZJ06, and ZJ08 on the first layer, deduce the coordinates of points ZJ01, ZJ03, and ZJ05 on the second layer. The coordinates of point ZJ07 are obtained by using the coordinates of points ZJ01, ZJ03, ZJ05, and ZJ07 in the second layer, measured from points ZJ02, ZJ04, ZJ06, and ZJ08 in the first layer, and the coordinates of points ZJ01, ZJ03, ZJ05, and ZJ07 in the second layer, calculated using the least squares method. The minimum threshold is then calculated, which represents the coordinates of points ZJ01, ZJ03, ZJ05, and ZJ07 in the second layer. The calculation process and results are shown in the table below.
