[0023] The following is in conjunction with the appendix Figures 1 to 3 The present application will be further described in detail with reference to the embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Please refer to Figure 1 This is a block diagram of an intelligent drawing device for steel cofferdams provided in an embodiment of the present invention. The intelligent drawing device for steel cofferdams includes: an initial condition setting module 110, adapted to set initial conditions, including initial parameters and the cofferdam structure form; the initial condition setting module 110 generates a planar layout of the pier cap and a planar layout of the steel casing based on the initial parameters; a cofferdam planar layout module 120, communicatively connected to the initial condition setting module 110, to draw the cofferdam planar layout based on the planar layout parameters, the planar layout of the pier cap, and the planar layout of the steel casing; and a wall segmentation module 130, communicatively connected to the cofferdam planar layout module 120, to segment the wall planar view of the cofferdam planar layout to obtain the wall. The module consists of a block structure diagram; a cofferdam profile drawing module 140, which is communicatively connected to the initial condition setting module 110 and the cofferdam plan layout module 120, to draw the cofferdam profile diagram based on the profile layout parameters, initial conditions, and plan layout parameters; a strut structure drawing module 150, which is communicatively connected to the initial condition setting module 110 and the cofferdam profile drawing module 140, to draw the cofferdam strut system structure diagram based on the strut structure parameters, initial conditions, and profile layout parameters; and an internal support structure drawing module 160, which is communicatively connected to the initial condition setting module 110 and the cofferdam plan layout module 120, to draw the cofferdam internal support structure diagram based on the internal support structure parameters, initial conditions, and plan layout parameters.

[0026] In this embodiment, the intelligent drawing device for steel cofferdams mainly includes an initial condition setting module 110, a cofferdam plan layout module 120, a wall block module 130, a cofferdam profile drawing module 140, a strut structure drawing module 150, and an internal support structure drawing module 160. The initial parameters include the cofferdam design water level, abutment elevation, cofferdam top elevation, bottom sealing concrete thickness, casing outer diameter, and the spacing of casings along the bridge longitudinal direction and transverse direction. The cofferdam design water level includes the cofferdam design high water level and cofferdam design low water level. The abutment elevation includes the abutment top elevation and abutment bottom elevation.

[0027] The initial condition setting module 110 is used to generate the plan layout of the pier cap and the plan layout of the steel casing, and to provide information on the cofferdam design water level, pier cap elevation, cofferdam top elevation, and bottom sealing concrete thickness involved in the cofferdam elevation layout. The cofferdam structure includes three types: single-wall steel caisson cofferdam, double-wall steel caisson cofferdam, and double-wall steel caisson cofferdam. Once the cofferdam structure is determined, the subsequent cofferdam plan layout module 120, cofferdam bottom plate layout module 170, cofferdam section drawing module 140, wall block module 130, and bottom plate system structure drawing module 180 will automatically change the parameters according to these three different cofferdam structure types.

[0028] The cofferdam plan layout module 120 includes a plan layout parameter setting unit and a unit for obtaining the plan layout form of the cofferdam's internal supports. The plan layout parameter setting unit is used to set the plan layout parameters, which include: overall wall thickness, horizontal truss spacing limit, vertical secondary beam spacing, outer wall plate thickness, inner wall plate thickness, partition plate thickness, vertical secondary beam angle steel type, internal support steel pipe diameter, and internal support steel pipe wall thickness.

[0029] When the cofferdam is one of the three different cofferdam structure forms, namely single-wall steel caisson, double-wall steel caisson, or double-wall steel caisson, the plan layout parameter setting unit will automatically filter the input parameters according to the parameters required by the cofferdam plan layout drawing, depending on the different cofferdam structure forms.

[0030] The unit for obtaining the planar layout of the cofferdam's internal support has the function of automatically obtaining the alignment and cross-sectional parameters of the cofferdam's planar layout. Based on the planar layout of the pier cap and the planar layout of the casing drawn by the initial condition setting module 110, the unit expands the planar layout of the pier cap while keeping the casing position unchanged. The original planar layout of the pier cap is deleted, and the expanded planar layout of the pier cap is retained. The expanded planar layout of the pier cap is used as the inner wall panel of the double-wall steel cofferdam or the wall panel of the single-wall steel cofferdam. Then, the longitudinal and transverse walls of the cofferdam are each divided into two equal parts. One longitudinal wall of the cofferdam and one transverse wall connected to the longitudinal wall of the cofferdam are retained, along with the casing within the range of the longitudinal and transverse walls of the cofferdam. The remaining cofferdam and casing plan layouts are deleted, avoiding the casing positions within the retained longitudinal and transverse sides of the cofferdam. The internal support layout is manually drawn, and the casings are deleted. The retained longitudinal and transverse walls and internal support layouts are obtained through the internal support plan layout form unit. At the same time, the plan layout parameters are introduced, and the symmetry of the cofferdam and support layout in the horizontal position is utilized. Through longitudinal and transverse mirroring, the cofferdam plan layout is obtained.

[0031] The wall segmentation module 130 is used to segment the wall plan view in the cofferdam plan layout drawing drawn by the cofferdam plan layout module 120. The wall segmentation module 130 includes the number of cuts along the horizontal and vertical directions of the cofferdam. The number of horizontal cuts n divides the cofferdam into n equal parts, and the number of vertical cuts m divides the cofferdam into m equal parts. The number of horizontal cuts n and the number of vertical cuts m are both assumed to be equal parts.

[0032] The cofferdam profile drawing module 140 is used to draw the sectional views of the steel cofferdam. The cofferdam profile views include a transverse sectional view of the bottom sealing construction condition, a longitudinal sectional view of the bottom sealing construction condition, a transverse sectional view of the pier cap construction condition, and a longitudinal sectional view of the pier cap construction condition. The profile layout parameters include the internal support elevation, the vertical spacing of the horizontal trusses, the parameters of the upper horizontal trusses, the parameters of the lower horizontal trusses, the top elevation of the struts, and the strut type. The upper horizontal truss parameters include the number of upper horizontal truss layers, the upper horizontal truss type, and the upper horizontal ring rib type; the lower horizontal truss parameters include the number of lower horizontal truss layers, the lower horizontal truss type, and the lower horizontal ring rib type. The cofferdam profile drawing module 140 is connected to the initial condition setting module 110 and the cofferdam plan layout module 120. The transverse section diagram of the bottom sealing construction condition, the longitudinal section diagram of the bottom sealing construction condition, the transverse section diagram of the pier cap construction condition, and the longitudinal section diagram of the pier cap construction condition are all drawn by calling the initial condition setting module 110, the cofferdam plan layout module 120, and the section layout parameters.

[0033] When drawing the transverse section diagram of the bottom sealing construction condition, the cofferdam section drawing module 140 retrieves the following parameters from the initial condition setting module 110: cofferdam design high water level, cofferdam design low water level, cofferdam top elevation, outer diameter of the casing, and spacing of the casing along the transverse direction of the bridge, as well as the following parameters from the cofferdam plan layout module 120: casket wall thickness, horizontal truss spacing limit, outer wall plate thickness, inner wall plate thickness, vertical secondary beam angle steel type, and inner support steel pipe diameter. These parameters are then combined with the section layout parameters for drawing.

[0034] When drawing the longitudinal section diagram of the bottom sealing construction condition, the cofferdam section drawing module 140 retrieves the cofferdam design high water level, cofferdam design low water level, cofferdam top elevation, outer diameter of the casing and spacing of the casing along the bridge direction from the initial condition setting module 110, as well as the caisson wall thickness, horizontal truss spacing limit, outer wall plate thickness, inner wall plate thickness, vertical secondary beam angle steel type and inner support steel pipe diameter from the cofferdam plan layout module 120, and draws the section diagram in combination with the section layout parameters.

[0035] When drawing the transverse section diagram of the pier construction condition, the cofferdam section drawing module 140 retrieves the cofferdam design high water level, cofferdam design low water level, pier top elevation, pier bottom elevation, bottom sealing concrete thickness, cofferdam top elevation, outer diameter of the casing, and spacing of the casing along the transverse direction of the bridge from the initial condition setting module 110, as well as the caisson wall thickness, horizontal truss spacing limit, outer wall plate thickness, inner wall plate thickness, vertical secondary beam angle steel type, and inner support steel pipe diameter from the cofferdam plan layout module 120, and draws the diagram in conjunction with the section layout parameters.

[0036] When drawing the longitudinal section of the pier construction condition, the cofferdam section drawing module 140 retrieves the following parameters from the initial condition setting module 110: cofferdam design high water level, cofferdam design low water level, pier top elevation, pier bottom elevation, bottom sealing concrete thickness, steel cofferdam top elevation, outer diameter of the casing, and spacing of the casing along the bridge direction. It also retrieves the following parameters from the cofferdam plan layout module 120: caisson wall thickness, horizontal truss spacing limit, outer wall plate thickness, inner wall plate thickness, vertical secondary beam angle steel type, and inner support steel pipe diameter. The drawing is then performed in conjunction with the section layout parameters.

[0037] The strut structure drawing module 150 is used to draw the structural diagram of the cofferdam strut system. The strut structure parameters include the thickness, width, and height of the strut base plate, the spacing between the strut gusset plates, and the diameter of the strut base pin. By default, the cofferdam strut base is placed in the middle of the main keel corner braces surrounding the steel casing. The strut top elevation and model are obtained by calling the strut top elevation and strut model parameters from the cofferdam profile drawing module 140. The struts are inclined towards the steel casing and welded to the steel casing at the same height as the strut top.

[0038] The internal support structure drawing module 160 is used to draw the internal support structure of the cofferdam. The parameters of the internal support structure include the diameter of the bottom plate of the internal support foot, the thickness of the bottom plate of the foot, the number of stiffening plates of the foot, the axial length of the foot, the chamfer length of the stiffening plate, the thickness of the stiffening plate, and the chamfer width of the stiffening plate. It also calls the longitudinal and transverse lengths of the internal support generated by the cofferdam plan layout module 120.

[0039] Furthermore, the intelligent drawing device for steel cofferdams also includes: a cofferdam bottom plate layout module 170, which is communicatively connected to the initial condition setting module 110, to draw a cofferdam bottom plate layout diagram based on the cofferdam structural form and bottom plate layout parameters. The cofferdam bottom plate layout diagram includes a planar layout diagram of the bottom plate main keel, and the bottom plate layout parameters include the bottom plate thickness, the bottom plate main beam model, the bottom plate secondary beam model, the side length of the square frame on the casing side, and the side length of the triangular frame on the casing side; and a bottom plate system structure drawing module 180, which is communicatively connected to the cofferdam bottom plate layout module 170, to draw a bottom plate system structure diagram based on the bottom plate system parameters and the cofferdam bottom plate layout diagram.

[0040] In this embodiment, the cofferdam bottom plate layout module 170 is used to draw the layout diagram of the steel cofferdam bottom plate. The cofferdam bottom plate layout module 170 is applicable to single-wall steel caissons and double-wall steel caissons; double-wall steel caissons do not have this module. The cofferdam bottom plate layout module 170 includes a bottom plate layout parameter setting unit, used to set the bottom plate layout parameters. The bottom plate layout parameters include the bottom plate thickness, the model of the bottom plate main beam, the model of the bottom plate secondary beam, and the side length of the triangle and rectangular frame formed by the main keel of the casing.

[0041] Given the diverse arrangements of the main keel of the cofferdam base slab, the base slab layout module 170 also includes a planar layout unit for the main keel of the base slab, used to draw the planar layout diagram of the main keel of the base slab. This planar layout unit generates the arrangement and location distribution of the main and secondary beams of the base slab for different configurations. Once the arrangement and location distribution of the main and secondary beams of the base slab for different configurations are determined, different base slab layout parameters are assigned, thus completing the drawing of the cofferdam base slab layout diagram.

[0042] The base plate system structure drawing module 180 is used to draw the structural diagram of the cofferdam base plate system. This module sets base plate system parameters, including the direction of the stiffening ribs, the spacing between the stiffening ribs, the type of the stiffening ribs, and the thickness of the stiffening plates. The module also includes a function to select the grid area enclosed by the main keel of the base plate. This grid selection is connected to the cofferdam base plate layout diagram in the cofferdam base plate layout module 170. During the drawing process, the module first selects base plate grids within the cofferdam base plate layout diagram. Each base plate grid is the area enclosed by adjacent longitudinal and transverse main keels in the steel cofferdam base plate layout diagram. After selecting a grid, the module calls the base plate system parameters within that grid to draw the base plate structure diagram within that grid. This process is repeated until all base plate grids are drawn. After all the base plate grid structure diagrams are drawn, the corresponding base plate grid structure diagrams are synchronized with the base plate layout diagrams. The original base plate layout diagrams without added base plate grid stiffening ribs are refined into base plate layout diagrams with added base plate grid stiffening ribs.

[0043] like Figure 2 The diagram shows a flowchart of an intelligent drawing method for steel cofferdams according to an embodiment of the present invention. The intelligent drawing method for steel cofferdams includes the following steps:

[0044] Step S101: Set initial conditions, which include initial parameters and cofferdam structure type.

[0045] Step S102: Generate the plan layout of the foundation and the plan layout of the steel casing based on the initial conditions.

[0046] Step S103: Draw the cofferdam plan layout based on the plan layout parameters, the pier plan layout, and the steel casing plan layout.

[0047] Step S104: Divide the wall plan of the cofferdam layout into blocks to obtain the wall block structure diagram.

[0048] Step S105: Draw the cofferdam profile based on the profile layout parameters, initial conditions, and planar layout parameters.

[0049] Step S106: Draw a structural diagram of the cofferdam strut system based on the strut structure parameters, initial conditions, and cross-sectional layout parameters.

[0050] Step S107: Draw the diagram of the cofferdam's internal support structure based on the internal support structure parameters, initial conditions, and cofferdam plan layout parameters.

[0051] In this embodiment, the initial parameters include the design high water level of the cofferdam, the design low water level of the cofferdam, the top elevation of the pier cap, the bottom elevation of the pier cap, the thickness of the bottom sealing concrete, the top elevation of the cofferdam, the outer diameter of the casing, the spacing parameters of the casing along the longitudinal direction of the bridge, and the spacing parameters of the casing along the transverse direction of the bridge.

[0052] This invention decomposes the complex task of drawing steel cofferdams into several relatively simple sub-tasks through a step-by-step, hierarchical drawing process, reducing the difficulty of drawing and improving efficiency. From setting initial conditions to drawing each structural diagram, each step is based on the results of the previous step. This progressive approach ensures coordination and consistency between the structural diagrams, avoiding errors and rework caused by inconsistencies in information. Furthermore, this method can flexibly generate corresponding cofferdam structural diagrams based on different initial conditions and parameters, exhibiting strong versatility and adaptability to meet the personalized needs of different engineering projects. This intelligent drawing method can significantly shorten the design cycle of steel cofferdams, improve design quality, and provide strong technical support for engineering construction.

[0053] Further, step S103 involves drawing a cofferdam plan layout based on the plan layout parameters, the pier plan layout, and the steel casing plan layout, specifically including the following steps:

[0054] Step S1031: Obtain the plan layout parameters, which include the overall wall thickness, horizontal truss spacing limit, vertical secondary beam spacing, outer wall plate thickness, inner wall plate thickness, partition plate thickness, vertical secondary beam angle steel type, inner support steel pipe diameter, and inner support steel pipe wall thickness.

[0055] Step S1032: Based on the steel casing plan layout, keeping the casing position unchanged, expand and cut the foundation plan layout to obtain the remaining 1 / 2 longitudinal wall panel and 1 / 2 transverse wall panel of the cofferdam after cutting.

[0056] Step S1033: Draw an internal support layout diagram based on the longitudinal wall panels and transverse wall panels of the cofferdam that are retained after cutting.

[0057] Step S1034: Based on the internal support layout diagram and plan layout parameters, and taking advantage of the symmetry between the cofferdam and the internal support layout diagram in the horizontal position, draw the plan layout diagram of the steel cofferdam by longitudinal and transverse mirroring.

[0058] In this embodiment, the plan layout of the steel cofferdam is drawn by inputting the parameters of the plan layout into the cofferdam plan layout module 120, and generating the 1 / 2 longitudinal side of the cofferdam and the 1 / 2 transverse side connected to the 1 / 2 longitudinal side and the internal support layout through the cofferdam internal support plan layout form module. The internal support plan layout of the entire cofferdam is obtained by mirroring by utilizing the symmetry of the cofferdam and support layout in the horizontal position.

[0059] Furthermore, in step S1032, based on the steel casing plan layout drawing while keeping the casing position unchanged, the foundation plan layout drawing is expanded and cut to obtain the remaining 1 / 2 longitudinal wall panel and 1 / 2 transverse wall panel of the cofferdam after cutting. Specifically, this includes the following steps:

[0060] Step S10321: After expanding the foundation plan, delete the original foundation plan and retain the expanded foundation plan.

[0061] Step S10322: Use the expanded pier plan as the inner wall panel of the double-walled steel cofferdam or the wall panel of the single-walled steel cofferdam.

[0062] Step S10323: After dividing the longitudinal wall panel and the transverse wall panel of the cofferdam into two equal parts, the remaining 1 / 2 longitudinal wall panel of the cofferdam, the 1 / 2 transverse wall panel connected to the 1 / 2 longitudinal wall panel of the cofferdam, and the casing within the range of the 1 / 2 longitudinal wall panel and the 1 / 2 transverse wall panel of the cofferdam are obtained.

[0063] Further, step S104 involves dividing the cofferdam's plan layout diagram into blocks to obtain a block structure diagram of the cofferdam, specifically including the following steps:

[0064] Step S1041: Obtain the cutting quantity parameters, which include the horizontal cutting quantity parameters and the vertical cutting quantity parameters.

[0065] Step S1042: Divide the cofferdam into equal parts along the transverse direction based on the transverse cutting quantity parameter.

[0066] Step S1043: Divide the cofferdam into equal sections along the longitudinal direction based on the longitudinal cutting quantity parameter.

[0067] The division points are set at the horizontal truss nodes of the steel cofferdam wall. If the division points are not at the horizontal truss nodes of the wall, the division points will be moved to the nearest horizontal truss node by default.

[0068] Furthermore, the intelligent drawing method for steel cofferdams also includes the following steps:

[0069] Step S107: Draw a cofferdam bottom plate layout diagram based on the cofferdam structure form and bottom plate layout parameters. The cofferdam structure forms include single-wall steel caissons and double-wall steel caissons. The bottom plate layout parameters include bottom plate thickness, bottom plate main beam model, bottom plate secondary beam model, side length of the square frame on the casing side, and side length of the triangular frame on the casing side.

[0070] Step S108: Draw the plan layout of the main keel of the base plate based on the base plate layout parameters.

[0071] Step S109: Draw a structural diagram of the bottom plate system based on the bottom plate system parameters and the layout diagram of the cofferdam bottom plate. The bottom plate system parameters include: the direction of the bottom plate stiffening ribs, the spacing of the bottom plate stiffening ribs, the model of the bottom plate stiffening ribs, and the thickness of the stiffening plate.

[0072] In this embodiment, the bottom plate layout parameters are input into the bottom plate layout module 170, and the layout forms and position distributions of different types of bottom plate main beams and secondary beams are set in the bottom plate main keel plan layout module. After the layout forms and position distributions of different types of bottom plate main and secondary beams are determined, the bottom plate main keel plan layout diagram is drawn by combining the various parameter information input into the steel cofferdam bottom plate layout diagram.

[0075] Step S1092: Call the base plate system parameters within the base plate grid to draw the base plate grid structure diagram until the base plate grid structure diagrams corresponding to all base plate grids are drawn.

After the bottom plate grid is selected, the bottom plate system parameter number is called in the grid to draw the bottom plate structure diagram in the selected grid.
