Abstract

The present invention relates to the field of construction planning technology, and specifically to a method for checking collisions between outdoor tree pits and outdoor pipelines. An outdoor terrain model, an outdoor pipeline model and a tree pit model are established according to existing drawings to increase the degree of visualization of real objects.

Therefore, the planning of green plant planting is completed by detecting the collision between the outdoor tree pit and the outdoor pipeline, which reduces the difficulty of work, saves planning time, improves work efficiency, avoids damage to the pipeline during construction, ensures construction efficiency, and meets actual use needs.

Description

Technical Field

[0001] The present invention relates to the technical field of construction planning, and in particular to a method for inspecting collisions between outdoor tree pits and outdoor pipelines. Background Art

[0002] When planting outdoor green trees, a tree pit is usually dug on the ground, and then the trees to be planted are placed in the tree pit for transplanting. Before the tree pit is constructed, the outdoor underground pipelines are often completed, and different types of pipelines are buried at different depths. When the tree pit is deep, it is easy to touch the underground pipelines during the construction of the tree pit, causing damage to the pipelines.

[0003] Therefore, managers usually design the types and locations of outdoor green plants first, and then draw outdoor green plant drawings according to the design plan. The outdoor green plant drawings include a planting instruction table and a plan distribution map of the green plants to be planted. The planting instruction table includes the type name of each green plant to be planted and the planting coordinates of each green plant to be planted. The planting coordinates are horizontal coordinates in the XY direction; then, the outdoor pipeline drawings and outdoor terrain drawings are combined to eliminate the positions where the tree pits may collide with the pipelines, and adjust the planting positions of the green plants to be planted. However, due to the complexity of various types of underground pipelines and lines, managers need to spend a lot of time and energy on planning, which is costly and inefficient, and has low accuracy. During actual construction, the outdoor green plant planting drawings and the planting instruction table's planting positions of the green plants to be planted need to be modified in real time, which makes the green plant planting construction planning inefficient and cannot meet the project schedule requirements. Summary of the Invention

[0004] In response to the problem of low efficiency in existing green plant construction, the purpose of the present invention is to provide a method for checking the collision between outdoor tree pits and outdoor pipelines, avoiding the collision between the green plant planting positions in the green plant planting drawings and the pipelines, and improving the green plant construction efficiency.

Collect all tree pit models to obtain a tree pit family.

[0020] The tree pit is a bowl-shaped structure, and the dimensions of the tree pit include the radius of the tree pit port and the depth of the tree pit.

[0021] It is further defined that step S3 includes the following steps:

[0022] S31. Create a green plant information table based on the planting instructions in the outdoor green plant drawing. The green plant information table includes the planting coordinates of the green plants to be planted on the outdoor terrain and the names of the types of green plants to be planted at the planting coordinates.

[0046] When planning to plant green plants in a certain area, the planting locations of the green plants in the area and the types of green plants to be planted in each planting location are usually planned according to the floor plan of the area. At this time, the planting distribution of the green plants in the floor plan of the area is drawn to obtain an outdoor green plant drawing. At the same time, the planting coordinates of each green plant and the name of the type of each green plant are recorded in the outdoor green plant drawing. The planting coordinates of the green plants are the plane coordinates in the X-axis direction and the Y-axis direction in the floor plan of the area. The types of green plants are, for example, nanmu, yew, and oblique floating tree.

[0047] refer to Figure 1 This embodiment provides a method for checking collisions between outdoor tree pits and outdoor pipelines, for checking whether outdoor pipelines will be damaged when digging tree pits for planting green plants, thereby improving the efficiency of green plant planting planning and construction work efficiency. The method for checking collisions between outdoor tree pits and outdoor pipelines includes the following steps:

[0048] S1. Establish an outdoor terrain model based on the outdoor terrain drawings, and establish an outdoor pipeline model based on the outdoor pipeline drawings;

[0049] S2. Establish a tree pit family according to the planting instruction table, wherein the tree pit family includes tree pit models corresponding to the types of green plants to be planted;

[0050] S3. Match the tree pit models with the corresponding green plants to be planted one by one according to the planting instruction table and the tree pit family, and set the tree pit models at the planting coordinate positions of the corresponding green plants to be planted to obtain an outdoor tree pit model;

[0051] S4. Combining the outdoor tree pit model with the outdoor terrain model so that all the tree pit models are disposed below the surface of the outdoor terrain model and all the tree pit models are in contact with the surface of the outdoor terrain model at corresponding positions, thereby obtaining an outdoor preset tree pit model.

[0052] S5. Combining the outdoor preset tree pit model with the outdoor pipeline model to obtain a tree pit pipeline collision model;

[0053] S6. Determine whether any tree pit model in the tree pit and pipeline collision model collides with the outdoor pipeline model. If so, modify the planting coordinates of the corresponding green plants to be planted in the planting instruction table and execute steps S3 to S6. If not, complete the inspection of the collision between the outdoor tree pit and the outdoor pipeline.

[0054] Specifically, step S1 includes the following steps:

[0055] S11. Import the outdoor terrain drawing into Revit software, and establish a visual three-dimensional model of the outdoor terrain through the terrain surface function to obtain an outdoor terrain model;

[0056] refer to Figure 2The outdoor terrain drawing is selected as the DWG format file of the CAD version, and the outdoor terrain drawing is imported into the Revit software. The terrain surface function in the volume and terrain tab menu of the Revit software is used to establish an outdoor terrain model. The outdoor terrain model is a visual three-dimensional model that represents the overall terrain structure of the area.

[0057] S12. Import the outdoor pipeline drawings into Revit software, and establish a visual three-dimensional model of the outdoor pipeline through the terrain surface function to obtain the outdoor pipeline model.

[0058] refer to Figure 3 , select the outdoor pipeline drawing as the DWG format file of the CAD version, import the outdoor pipeline drawing into the Revit software, and also use the terrain surface function in the volume and terrain tab menu of the Revit software to build the outdoor pipeline model. The outdoor pipeline model is a visual three-dimensional image that represents the buried pipelines and line layout in the area.

[0059] Step S2 is specifically as follows:

[0060] Select the planting instruction table in the outdoor green plant drawing to obtain all types of green plants to be planted in the planting instruction table, determine the tree pit size based on the ground diameter of each type of green plant, draw the corresponding tree pit model based on the tree pit size, and collect all the tree pit models to obtain a tree pit family; the tree pit is a bowl-shaped structure, and the size of the tree pit includes the radius of the tree pit port and the depth of the tree pit.

[0061] refer to Figure 4 , obtain the types of green plants to be planted from the outdoor green plant drawings, and use the metric conventional model family template in Revit software to establish a tree pit family. The tree pit family includes tree pit models of various sizes. Each size of tree pit model corresponds to a type of green plant, that is, different types of green plants require different tree pit sizes, and the tree pit size is usually determined according to the ground diameter of the green plant; the tree pit is usually a bowl-shaped structure, so the tree pit model is selected as a bowl-shaped structure, the port of the tree pit model is a horizontally set circle, and the bottom of the tree pit model is an arc structure covering the bottom of the port. The size of the tree pit model includes the radius of the port and the depth of the arc surface. The port radius is usually the inner diameter of the port, and the depth of the arc surface is the depth of the tree pit model.

[0062] Collecting all tree pit models of different sizes to obtain a tree pit family makes it convenient to select the tree pit model of corresponding size according to the type of green plants when using it, saving time and improving efficiency.

[0063] Step S3 includes the following steps:

[0064] S31. Create a green plant information table based on the planting instructions in the outdoor green plant drawing. The green plant information table includes the planting coordinates of the green plants to be planted on the outdoor terrain and the names of the types of green plants to be planted at the planting coordinates. The planting coordinates are plane coordinates.

[0065] Since the planting instruction table is displayed in DWG format in the outdoor green plant drawing, it is necessary to import the contents recorded in the planting instruction table into Excel to obtain the green plant information table. Referring to Table 1, the green plant information table contains the planting coordinates of the green plants to be planted on the outdoor terrain and the type name of the green plants to be planted at the planting coordinates.

[0066] Table 1 Green plant information table

[0067]

[0068] The planting coordinates are represented by the X-axis coordinates and the Y-axis coordinates of the outdoor terrain on the horizontal plane. During actual construction, the outdoor planting positions of green plants can also be determined based on the planting coordinates.

[0069] S32, importing the green plant information table into the Dynamo plug-in in the Revit software to obtain the planting coordinates of each green plant to be planted and the name of the green plant species to be planted that matches the planting coordinates;

[0070] The summarized plant information table is saved and then imported into Dynamo software. Dynamo software obtains the planting coordinates of each plant and the type of plant to be planted at each plant coordinate.

[0071] S33. Import the tree pit family into Revit software, use the Dynamo plug-in to match the species name of each green plant to be planted with the corresponding tree pit model, and set the matched tree pit model at the corresponding planting coordinate position according to the planting coordinates of each green plant to obtain an outdoor tree pit model. All tree pit models in the outdoor tree pit model have the same elevation.

[0072] refer to Figure 5 and Figure 6 , import the tree pit family into Dynamo software. Dynamo software matches the tree pit models in the tree pit family according to the plant type names in the plant information table one by one, so that each plant to be planted is matched with a tree pit model. Then, according to the planting coordinates of each plant to be planted, the matching tree pit model is moved to the corresponding coordinate position to obtain the outdoor tree pit model, so that the center of all tree pit model ports in the outdoor tree pit model is located at the corresponding coordinate position. Since the planting coordinates are plane coordinates, all tree pit model ports in the outdoor tree pit model are located at the same horizontal position. At this time, the elevations of the tree pit models are the same, and all tree pit models are arranged along the plane of the outdoor terrain.

[0073] Step S4 includes the following steps:

[0074] S41. Import the outdoor tree pit model and the outdoor terrain model into Revit software, so that the horizontal coordinates of the outdoor tree pit model are aligned with the horizontal coordinates of the outdoor terrain model;

[0075] S42, setting all the tree pit models in the outdoor tree pit model below the outdoor terrain model;

[0076] S43. Move the tree pit models in step S42 in sequence and adjust the elevation of each tree pit model until the tree pit model contacts the surface of the outdoor terrain model, thereby obtaining an outdoor preset tree pit model.

[0077] refer to Figure 7 and Figure 8 In Revit software, use the Dynamo plug-in to obtain the outdoor tree pit model and save it, then import the outdoor tree pit model and the outdoor terrain model into Revit software, so that the X-axis and Y-axis of the outdoor tree pit model and the outdoor terrain model are aligned, and the coordinate origin is aligned, ensuring that the positions of all tree pit models in the outdoor tree pit model are aligned with the coordinates corresponding to the outdoor terrain model. At this time, the outdoor tree pit model can be set above, in the middle or below the outdoor terrain model. Since the tree pit needs to be dug below the outdoor terrain model, first choose to place the outdoor tree pit model below the outdoor terrain model.

[0078] Since the elevations of the tree pits in the outdoor tree pit model are the same, and the elevation of the actual tree pit is set according to the height of the terrain, it is necessary to adjust the elevation of each tree pit model, and move each tree pit model so that the port of the tree pit model contacts the upper surface of the outdoor terrain model. At the same time, the tree pit model is located below the upper surface of the outdoor terrain model to obtain an outdoor preset tree pit model, which fully simulates the scene of digging tree pits outdoors, that is, the position and depth of the tree pits dug at the outdoor surface.

[0079] Step S5 is specifically as follows:

[0080] Import the outdoor preset tree pit model and the outdoor pipeline model into Revit software, overlap the spatial coordinates of the outdoor preset tree pit model with the spatial coordinates of the outdoor pipeline model, and superimpose the outdoor pipeline model with the outdoor terrain model so that the tree pit model is located in the outdoor pipeline model to obtain the tree pit pipeline collision model.

[0081] refer to Figure 9After saving the outdoor preset tree pit model, import both the outdoor preset tree pit model and the outdoor pipeline model into the Revit software, or directly insert the outdoor pipeline model after completing the establishment of the outdoor preset tree pit model to obtain a model in which both the outdoor preset tree pit model and the outdoor pipeline model exist; since the outdoor pipeline will not be fixed at the same height when laid, the obtained outdoor pipeline model is a three-dimensional model diagram, and since the buried depth of each pipeline or line is laid according to the design size, the spatial coordinates of the outdoor pipeline model are overlapped with the spatial coordinates of the outdoor preset tree pit model, so that the outdoor pipeline model can be set at the corresponding position in the outdoor terrain model to obtain a tree pit pipeline collision model.

[0082] The tree pit and pipeline collision model is used to simulate the actual working conditions of outdoor buried pipelines. At this time, there are tree pit models with different elevations in the outdoor preset tree pit model. The staff can use Revit software to check the location where there is a collision between the tree pit model and the outdoor pipeline model, which is convenient for inspection and more intuitively represents the collision situation between the tree pit model and the pipeline.

[0083] Step S6 is specifically as follows:

[0084] Use Revit software to check whether there is a collision between any tree pit model and the outdoor pipeline model in the tree pit pipeline collision model;

[0085] If the detection result is yes, the plane coordinates of the tree pit model that collides with the outdoor pipeline model are recorded, indicating that the planting coordinates corresponding to the coordinates are inaccurate and need to be modified; and the planting coordinates corresponding to the plane coordinates are modified in the planting description table, and then steps S3 to S6 are executed until all tree pit models in the tree pit pipeline collision model do not collide with the outdoor pipeline model, and then the process ends; in order to reduce the number of modifications, designers usually move the colliding tree pit model directly in the Revit software so that the tree pit model does not collide with the outdoor pipeline model, and then record the horizontal coordinates of the moved tree pit model and modify the moved coordinates accordingly in the planting description table. After all the colliding tree pit models are adjusted, steps S3 to S6 are executed again to check whether there is a collision between the tree pit model and the outdoor pipeline model; the inspection is completed until there is no collision, that is, the inspection result is no, and the outdoor green plant drawings can be uniformly modified at this time; if there are many pipelines around the tree pit model that cannot be avoided, the plan to plant green plants at this location can be canceled according to the actual situation, and the outdoor green plant drawings can be modified synchronously.

[0086] If the test result is negative, the process ends. By analyzing the collision between outdoor tree pits and outdoor pipelines, we can intuitively understand the layout of outdoor tree pits, the laying of outdoor pipelines, and the collision between outdoor tree pits and outdoor pipelines. This effectively avoids pipeline damage during construction, ensures the accuracy of green plant planting drawings, improves work efficiency, and saves planning time.
