[0074] S300: based on the pipe wall unit with the number, obtain the two-dimensional view corresponding to the pipe wall unit with the number.

[0075] Specifically, after obtaining the pipe wall unit with the number, the projection of the pipe wall unit under a certain view angle can obtain the two-dimensional view, and the two-dimensional view corresponds to the pipe wall unit, so it should also correspond to the number.

[0076] S400: extract the relative position data of the pipe wall unit in the three-dimensional model;

[0077] Specifically, the pipe wall unit has a relative position with respect to the three-dimensional model, such as a relative distance, height or even inclination with respect to a certain reference surface in the three-dimensional model, to form the relative position data. This relative position data can be used as the basis for determining the position of the parts in the pipe wall unit, so it can naturally be used as a position reference for the manufacture and installation of the guide pipe in the pipe wall unit.

[0078] S500: corresponding annotation of the relative position data in the two-dimensional view, to obtain the deepening drawing, which is used to guide the on-site processing and manufacturing.

[0079] Specifically, the relative position data is annotated one by one in the two-dimensional view, and finally the deepening drawing is obtained. The so-called deepening drawing can be applied to the on-site manufacturing and processing of the pipe wall unit, especially the manufacturing of the pipe wall unit containing the plate structure, and the non-conventional hole formed by the guide pipe on the pipe wall unit does not need to be positioned and fitted manually.

[0080] In actual application, in the established bridge tower three-dimensional model, the cable guide pipe and the tower wall where the cable guide pipe is located are cut to form a pipe wall unit, the bridge tower model is assembled by a plurality of anchor boxes through the cross section, the cutting process ensures the complete extraction of the preset part of the cable guide pipe and the tower wall where the cable guide pipe is located, the pipe wall unit is named and numbered according to different parts and installation nodes of the bridge tower, the components of the pipe wall unit and the specific installation positions thereof can be covered, so that different parts and nodes can be distinguished, for each pipe wall unit with a number, a specific perspective projection is performed to generate a corresponding two-dimensional view, the two-dimensional view can intuitively reflect the structure and position relationship of the pipe wall unit, the relative position data of the pipe wall unit is extracted from the three-dimensional model, which can include distance, height and inclination, and the acquisition of the relative position data provides a basis for the subsequent accurate manufacturing and position determination of the pipe wall unit, the relative position data is marked in the two-dimensional view to generate a deepening drawing, which can provide detailed guidance for the field manufacturing and processing of the pipe wall unit containing a plate structure, and is suitable for the accurate positioning of the non-standard hole position of the cable guide pipe in the pipe wall unit, reduces manual intervention, thereby reducing time consumption and positioning difficulty, and improves manufacturing accuracy.

[0081] The deepening drawing formed quickly can be applied to the manufacturing of the special-shaped perforated plate of the cable guide pipe, can fully solve the difficulties in the manufacturing of the plate parts in the three-dimensional space, improves the production efficiency, saves most of the time of the deepening drawing personnel, plays a good reference role for the subsequent manufacturing of similar bridges, greatly reduces the workload and difficulty of the two-dimensional drawing personnel, embodies the intelligent design idea, reduces the cost, and can realize accurate manufacturing.

[0082] As an optional embodiment of the present application, the integral cutting of the cable guide pipe in the three-dimensional model of the bridge tower and the tower wall where the cable guide pipe is located to obtain a pipe wall unit comprises:

[0083] According to the type of the anchor box in the three-dimensional model, a corresponding cross section division template is determined;

[0084] According to the cross section division template, the cross sections of all anchor boxes are determined by querying in the three-dimensional model;

[0085] Taking a certain steel tower project design as an example, the axis of the steel tower is in space, and the projection angle with the bridge direction (i.e. the extension direction of the bridge contour) is 62.2°, and the projection angle with the transverse bridge direction (i.e. the width direction of the bridge) is 76.8°, the tower column axis is 87.445m long, the cross section gradually changes from 5.2m*8.5m to 3.2m*4m, and a horizontal partition is arranged every 2m in the steel tower.

[0086] When modeling, several steel anchor boxes with characteristics are selected according to the design intention to make templates, for example, there are three characteristics, three templates are created, each template contains different section division, then a module called knowledge engineering matrix in catia is used, the created templates are automatically generated in the design position through script writing according to the design positioning, for example, template 1 has 10, template 2 has 20, and template 3 has 30, and the section containing all anchor boxes is inquired in the three-dimensional model.

[0087] Based on the pipeline identification of the cable guide pipe and the section, the cutting range of the pipe wall unit is determined;

[0088] In the created templates mentioned above, different plate parts have the same label, for example, the small mark after WB is different, so when writing the extraction script, it can be queried, and only this part is cut when cutting the outer wall plate, and the pipeline identification is included in the naming of the pipe wall unit, and the section shape of the pipeline exists, and the cutting range is obtained by generally meeting the preset area and the preset thickness.

[0089] The "Query" function is used to search for features located below the applied feature, verify the specified expression, and add the found objects to the list, and all product instances (including invisible) and their references are returned.

[0090] According to the cutting range, the three-dimensional model is cut to obtain the pipe wall unit, and the pipe wall unit includes a wall plate unit.

[0091] Specifically, by appropriately increasing the designed pipe diameter, the model generated in catia is cut according to automatic Boolean operation without manual intervention, and the pipe wall unit appears in the form of a plate, which can cover most of the pipe wall and can adapt to the actual needs of the anchor box.

[0092] In actual application, the section of the anchor box is searched and recognized based on the template, and the section is determined, and then the sections of all anchor boxes can be quickly determined and the cutting of the section containing the cable guide pipe is realized to obtain the pipe wall unit.

[0093] As an optional embodiment of the present application, the pipe wall unit is named based on different parts and nodes of the bridge tower to obtain the corresponding number of the pipe wall unit, including:

[0094] The parts contained in the pipe wall unit are determined, and the installation part and the connection node of the parts are obtained;

[0095] For each pipe wall unit, the parts contained therein can be identified by comparison with the parts in the preset part library to determine the part type, or distinguished by the naming of the parts in the feature tree. After the parts are identified, the mounting positions and nodes of the parts can be determined by the part naming or other parts in the adjacent positions.

[0096] Obtaining a serial number of a section division template in which the pipe wall unit is located;

[0097] As shown in Figure 2 The anchor box is segmented one segment at a time, and the outer wall to be cut is the outer wall of the (steel) anchor box. When modeling, several steel anchor boxes with characteristics are selected according to the design intention to make templates. For example, there are three characteristics, so three templates are created, each of which contains different section divisions. Then, a module called knowledge engineering matrix in CATIA can be used to automatically generate the templates created in the design position according to the design positioning through script writing. For example, template 1 has 10, template 2 has 20, and template 3 has 30. They can be generated in the design position according to the matrix according to the category, and finally form a complete steel tower section.

[0098] Based on the serial number, the mounting position and the connecting node, the number corresponding to the pipe wall unit is determined.

[0099] Specifically, the number is a combination of the serial number of the division template, the mounting position and the node. For example, M1_N5-0_3, M1_N5a-1_3 and M1_N6-2_3 are the serial numbers of three parts, respectively. Among them, M1 represents the first template on the right, N5 and N6 represent the part composition inside the steel anchor box, N1, N2 and N3 represent the part composition of the steel anchor box outer wall plate and stiffening, and the tail mark 3 represents the outer alignment, and 0 represents the center alignment.

[0100] In actual application, by combining the template serial number, the mounting position and the node of the pipe wall unit, the number determined by the setting rule is determined, which can distinguish the pipe wall unit and contain the type and mounting position of the anchor box, facilitating the identification of each part based on the projection of the pipe wall unit.

[0101] As shown in Figure 3 and Figure 4 As an optional embodiment of the present application, the extraction of the relative position data of the pipe wall unit in the three-dimensional model comprises:

[0102] Obtaining a reference surface in the three-dimensional model, and marking the pipe wall unit in the three-dimensional model;

[0103] Specifically, the reference surface to be projected is designated in advance, generally a plane parallel or close to parallel to the pipe wall unit, that is, a plane with an angle difference from the surface of the pipe wall unit within a preset angle range, and all the pipe wall units are marked, which can be performed by picking up and color marking, and the reference surface can be provided with multiple reference surfaces, and two or more reference surfaces can facilitate positioning the cable guide pipe from multiple planes.

[0104] The boundary of the marked pipe wall unit is recognized, and a geometric element of the boundary is extracted, the geometric element including a line segment and a circle;

[0105] The boundary of the pipe wall unit can be directly picked up, which is an actual line or plane in the three-dimensional model, and the geometric element of the boundary includes a straight line, a curve and a circle, and the cross section of the circle is generally an ellipse.

[0106] The geometric element corresponding to a length greater than a preset length is screened, and the relative position data between the screened geometric element and the reference surface or the connected structure is determined.

[0107] In the relative position data between the screened geometric element and the connected structure, Figure 3 corresponding to the relative position data between the screened geometric element and the connected structure, Figure 4 which includes the number of anchor beam segments, the relevant parameters for process drawing to guide the manufacture and installation of the anchor beam, such as length, angle, relative position relationship, etc.

[0108] Specifically, the boundary of the surface is obtained and deconstructed, and in the foregoing actual example, a circular element with a diameter greater than 200 mm is screened out, which can be the cross section of the cable guide pipe; a line segment with a length of 1000 mm is screened, which can be the connecting part or position between the cable guide pipe and other structures.

[0109] In actual application of the embodiment, the selection of the reference surface, the identification of the pipe wall unit and the extraction of the element facilitate the extraction of the geometric element of the pipe wall unit, and further determine the relative position data between the geometric element and the connected structure, thereby improving the positioning accuracy of the installation of the core part of the cable guide pipe, and the relative position data in combination with the two-dimensional drawing can provide direct reference for the subsequent installation of the cable guide pipe in the field.

[0110] As shown in Figure 5 and Figure 6 as an optional embodiment of the application, the screening of the geometric element corresponding to a length greater than a preset length, and the determination of the relative position data between the screened geometric element and the reference surface or the connected structure include:

[0111] screening a circle with a diameter greater than a preset diameter, and projecting the screened circle to the reference surface to obtain a projected shape;

[0112] When the circle is an ellipse, it is the long axis of the ellipse, projected on at least two reference surfaces, the reference surfaces are selected as two non-parallel planes, and the reference can be installed from different reference planes.

[0113] Identify the first relative position data of the projection shape relative to the reference surface;

[0114] When selecting the relative position data, several key points are selected on the projection shape, such as the center of the circle and the first relative position data of the reference surface. For other shapes such as rectangles, four vertices are selected, and for straight lines, endpoints and center points are selected. The relative position data can be directly calculated by the tool in the software, such as the measurement module of Catia. The first relative position data includes the distance from the point to the straight line, the distance from the point to the plane, the inclination angle of the line relative to the reference surface, and the inclination angle of the surface relative to the reference surface.

[0115] Select the line segment with a length greater than the preset distance, and pick up the connected structure connected to the end of the line segment;

[0116] The structure connected to the end of the line segment indicates that it may be a connecting part or position between the cable guide pipe and other structures. The name of the connected structure exists in the feature tree of the software (named during modeling).

[0117] Identify the second relative position data of the line segment relative to the connected structure;

[0118] The second position data and the first position data are the same type of data, so the second position data can show the position relationship of the cable guide pipe relative to the connected structure.

[0119] The relative position data includes the first relative position data and the second relative position data.

[0120] As Figure 5 and Figure 6 are the annotation diagrams of the deepening drawings of the adjacent numbered segments, which respectively show the two-dimensional schematic diagram of the position annotation cable guide pipe relative to the bridge tower top and the side (east side), the bridge tower center line, etc. It should be noted that, Figure 5 and Figure 6 are two schematic drawings of batch plotting, the unit of size is millimeter, which is the steel anchor box of Tuojing Bridge cable tower, N2 is the part on the side of concrete beam (M), and the bevel form is subject to the welding process, represents the stirrup steel bar hole and the PBL shear key hole, with a diameter of 60mm, represents the stirrup steel bar hole, with a diameter of 50mm.

[0121] In actual application, by screening the set elements, the circular surface and the length direction line segment of the cable guide pipe can be determined, and then the position relationship with the reference plane is determined based on the circular surface and the line segment respectively, which can be directly marked on the two-dimensional drawing and does not need to be measured manually.

[0122] As an optional embodiment of the present application, the obtaining of the two-dimensional view corresponding to the pipe wall unit with the number based on the pipe wall unit with the number comprises:

[0123] The pipe wall unit is projected according to the set perspective, and the projection result is matched with the number of the corresponding pipe wall unit, so as to obtain the two-dimensional view corresponding to the pipe wall unit with the number.

[0124] Specifically, the set perspective is generally selected as the front view perspective, and the front view drawing of the numbered geometry (pipe wall unit) can be obtained by batch through the CATIA engineering drawing module by means of the CATIA, so as to finally obtain the drawing in the dwg format with the number, and the drawing is batched.

[0125] The above realizes the front view drawing of the pipe wall unit, and the two-dimensional drawing has the number, which is convenient for distinguishing and generating the subsequent deepening drawing.

[0126] When the relative position data is marked in the two-dimensional view, the marking is mainly based on the cable guide pipe, and the relative position data is combined with the two-dimensional view.

[0127] As an optional embodiment of the present application, the three-dimensional model of the bridge tower is pre-established, and the step of pre-establishing the three-dimensional model of the bridge tower comprises:

[0128] Establishing a central axis reference line of the bridge tower;

[0129] Specifically, the central axis reference line is taken as a reference to establish a plurality of bridge tower sections at different heights, and the modeling process can be based on a three-dimensional software, such as the CATIA. At present, the CATIA is used to build the bridge tower section model in a complex structure, which is a known technology. The improvement of the present embodiment is that the bridge tower section is established, and the base model is fitted by splicing a plurality of bridge tower sections.

[0130] The positioning data of the cable guide pipe is imported in the form of a design table, the guide pipe line is generated in each bridge tower section based on the positioning data, the cable guide pipe with a wall thickness is formed in each bridge tower section based on the guide pipe line;

[0131] Specifically, after the positioning data of the cable guide pipe is counted through an Excel table, the cable guide pipe line is automatically drawn in CATIA through a design table, and then all the tower walls are fitted to form the entire steel tower contour model, wherein the positioning data includes length, trend, angle data, and also includes elevation positioning, and the left and right sides and the along-bridge direction side of the bridge tower are distinguished by different letters in the modeling. The guide pipe line is drawn through the positioning data, and then the model contour can be completed by sweeping based on the set wall thickness.

[0132] The cross section of the bridge tower with the cable guide pipe is fitted, and auxiliary partitions and reinforcing ribs are established to obtain the three-dimensional model of the bridge tower.

[0133] Specifically, the tower walls generated by the engineering template matrix are fitted, and finally the partitions and transverse and longitudinal stiffeners are established thereon, and the steel tower model is completed.

[0134] In actual application, the guide pipe can be quickly established through batch import of the design table, and the bridge tower cross section used for final fitting meets the positioning requirements of the cable guide pipe, thereby meeting the subsequent accurate drawing requirements of multiple cable guide pipes.

[0135] As shown in Figure 7 As an optional embodiment of the present application, after the relative position data is marked in the two-dimensional view to obtain the deepened drawing, the following steps are further included:

[0136] The guide cable hole cutting allowance based on the deepened drawing is counted to obtain a two-dimensional allowance, wherein the guide cable hole cutting allowance is the cutting allowance when at least two sections of the cable guide pipe are spliced in the guide cable hole.

[0137] Specifically, in combination with the two-dimensional drawing allowance statistics on site, the statistics can be manually inputted, and since the initial actual cutting of the cable guide pipe is based on the deepened drawing.

[0138] The guide cable hole splicing allowance based on the three-dimensional model of the bridge tower is obtained to obtain a three-dimensional allowance.

[0139] The guide cable hole splicing allowance relates to the actual allowance when the cable guide pipe is spliced in the guide cable hole according to the three-dimensional bridge tower model. The allowance is used for facilitating the welding of the guide cable pipe in the guide cable hole.

[0140] The two-dimensional allowance and the three-dimensional allowance are compared, and a scrap management database is constructed according to the comparison result.

[0141] Specifically, the two-dimensional allowance and the three-dimensional allowance are compared, the two-dimensional allowance and the three-dimensional allowance of the cable guide pipe at the same height are corresponded, when the allowance difference is too large, the cutting optimization basis can be provided for the subsequent two-dimensional allowance, and after the cutting of the same batch is completed, the allowance can be preliminarily controlled, and the unified allocation of the insufficient allowance is facilitated.

[0142] When the embodiment is applied in practice, by establishing the excess material management database, that is, the Catalog (product directory) excess material management system, unnecessary excess material and potential causes of waste material can be found, so that measures (such as optimizing the two-dimensional allowance, reducing, or utilizing waste material) can be taken to reduce material waste and improve overall efficiency.

[0143] As an optional embodiment of the application, the part guide method for cable guide pipe perforation further comprises:

[0144] Based on the wall plate unit, the virtual fixing of the angle template is performed in advance;

[0145] Specifically, the spatial positioning of the small cross rib and the wall plate unit is realized through the virtual fixing of the angle template, the angle template is fixed in advance based on the cross rib (partition) position line on the parts of the wall plate unit, the position accuracy and the firm fixing of the angle template are ensured, then the positioning cross rib is assembled along the cross rib position line on the wall plate, and the spatial assembly angle of the wall plate unit is controlled through the angle template.

[0146] Based on the virtually fixed angle template, the wall plate unit is overlapped with the concrete formwork model, and the overlapping error therebetween is detected;

[0147] Specifically, after the virtual fixing of the angle template, the wall plate unit is assembled and combined with the actual use, and is overlapped with the concrete formwork model, the overlapping error is based on the set positioning points, the positioning points can be set based on the angle sample, and the overlapping error is manifested as the distance difference after overlapping.

[0148] The position of the angle template for virtual fixing is adjusted according to the overlapping error, until the overlapping error meets the preset error accuracy.

[0149] Generally, the actual-theoretical error distance is required to be less than 0.5 mm, when the actual-theoretical error distance is greater than or equal to 0.5 mm, the distance of the angle template relative to the cross rib position line should be adjusted, and finally the overlapping error meets the preset error accuracy.

[0150] When the guide wall plate unit is reorganized, a boundary extraction script is created to reorganize the system line and the outer wall extraction line of the steel tower, which is a preparation for exporting the white drawing. The white drawing is obtained by batch plotting, and the objects recognized by the batch plotting script are the outer contour lines. The system line and the outer contour line are both projection objects, so they need to be reorganized. The system line can be understood as a guide pipe line, and the intersection of the system line and the outer wall plate needs to be reorganized here. After reorganizing with the outer contour, the complete white drawing is exported. At this time, the white drawing contains not only the outer contour but also the hole points of the guide pipe for two-dimensional marking, which facilitates the two-dimensional positioning marking of the marking personnel and avoids the need for designers to calculate the positioning points one by one according to the design principles.

[0151] In actual application, by virtually fixing the angle sample plate and coinciding it with the wall plate unit and the concrete formwork model (the formwork model is a concrete model, and the concrete is wrapped outside the bridge tower), the coincidence error between the two can be accurately detected. Virtual fixing and adjustment before actual construction can avoid rework or material waste caused by errors. After confirming that the position of the angle sample plate is appropriate, actual construction can be carried out, which can significantly improve resource utilization efficiency. Through computer simulation and virtual fixing, the best construction scheme can be quickly found to avoid trial and error on site, thereby saving construction time and improving work efficiency. By detecting the coincidence error and adjusting it, problems or defects in actual installation can be found in advance to promote the optimization and perfection of the installation of the bridge tower where the guide pipe is located.
