Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and relates to a drainage ditch system, specifically a pre-buried drainage ditch system which is designed in depth by using BIM technology and is suitable for building roofs, basements and other areas. Background Art

[0002] At present, in the process of building construction, drainage ditch systems, such as drainage ditches installed on non-walkable roofs and drainage ditches installed in underground garages, are usually constructed by brick masonry or lightweight concrete pouring. Taking brick-built drainage ditches as an example, waterproof materials need to be applied on the surface after the masonry is completed to ensure the drainage function while achieving the water-tightness of the structure and avoid leakage in the later stage. In the deepening stage before this construction process, CAD software is usually used for deepening.

[0003] Although the above work process is mature, the quality of waterproof material coating is difficult to guarantee. The base material is easily damaged during the construction process, resulting in the drainage function not meeting the design standards. In addition, the conventional deepening method can only collect and process information on a two-dimensional plane, and cannot intuitively deepen the drainage ditch through a three-dimensional level, which is not convenient for on-site construction operations.

[0022] The specific embodiments of the utility model will be described in detail in this section, and the preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The embodiment of the utility model provides a BIM-based pre-buried drainage ditch system, which is composed of the pre-buried drainage ditch system and the BIM-based deepening method. The pre-buried drainage ditch system includes a side wall module 11; a connecting rod 12; a non-rainwater bucket base module 13; a top cover module 14; a rainwater bucket base module 23; and a rainwater bucket reserved hole 24.

[0024] A top cover module 14, a side wall module 11 on each side and a base module 13 without a rain gutter or a base module 23 with a rain gutter constitute a section of a pre-buried drainage ditch, and each section of the pre-buried drainage ditch is connected by a connecting rod 12 to form a pre-buried drainage ditch system.

[0025] A transverse groove is provided on the inner wall of the side wall module 11, and the groove cooperates with the connecting rod 12 to ensure complete fit. The groove is located in the middle and upper part of the side wall module 11, and the length of a connecting rod 12 is at least longer than the width of the side wall module 11. The width of the cross section of the connecting rod 12 is greater than the width of the groove. The bottom surface of the side wall module 11 is an inclined bottom surface, and the bottom of the inner wall is rounded. The inner side of the top of the side wall module 11 is provided with a right-angle groove that cooperates with the side of the top cover module 14, which is convenient for installation with the top cover module 14.

[0026] The overall cross-section of the base module 13 without rain gutter and the base module 23 with rain gutter are both regular trapezoids, with the long side facing downward, and fit with the concrete structure surface of the proposed construction location. The rain gutter base module 23 has a reserved rain gutter hole 23, which matches the size of the original designed drop gutter to ensure installation with the drop gutter. The inclined surfaces on both sides of the base module 13 without rain gutter and the base module 23 with rain gutter match the inclined bottom surface of the side wall module 11.

[0027] The top cover module 14 has a plurality of elliptical holes, which are arranged adjacently and symmetrically. The top cover module 14 has a rectangular cross section, one of the long sides of which is an arc, that is, the top surface is an arc-shaped surface.

[0028] The materials of the top cover module 14 , the side wall module 11 , the connecting rod 12 , the base module without rain gutter 13 and the base module with rain gutter 23 are all made of concrete.

[0029] The in-depth method based on BIM was completed based on the Revit series software produced by ATUODESK.

[0030] Preferably, all the above modules can be adjusted in size according to the original designed drainage ditch size to meet different drainage requirements.

[0031] Preferably, the BIM-based deepening method can produce a summary table of engineering quantities after completing the deepening design, which is convenient for the statistics of engineering quantities and the confirmation of engineering costs in the later stage.

[0032] Specifically, before the implementation of the pre-buried drainage ditch system, in-depth design is required. Figure 4 , using the Revit series software produced by ATUODESK to complete the in-depth design, specifically: disassemble the original construction drawings using CAD software, and then use the Revit software to import the drawings to input the disassembled drawings; after the drawings are input, use the Revit software structural modeling function to complete the modeling of structural related components such as foundations, shear walls, frame columns, frame beams, and then use the Revit software structural modeling function to complete the modeling of building related components such as masonry walls, doors, windows, and roofs; use the original design instructions, diagrams, etc., based on the model, complete the drainage ditch Identify; import the drainage ditch module family file, whose format is .RFA; select the appropriate module according to the position of the rain gutter, that is, the base module 13 without rain gutter and the base module 23 with rain gutter. It should be noted that the position of the rain gutter needs to maintain a one-to-one correspondence with the rain gutter reserved hole 24 on the base module 23 with rain gutter to ensure that the subsequent rain gutter is installed correctly; then complete the module layout of the overall drainage pipe; finally, use the Revit software export drawing function to output two-dimensional detailed drawings and three-dimensional detailed axis views for construction site operations. Preferably, the number of modules can also be counted to facilitate subsequent engineering quantity calculations.

[0033] In the specific installation and construction of the drainage ditch, firstly, the layout and positioning of the drainage ditch are completed according to the two-dimensional deepening drawings and the three-dimensional deepening axial drawings. According to the completed layout and positioning results, the rainwater bucket base module 23 is arranged for the position of the downspout, and the non-rainwater bucket base module 13 is arranged for the position where the downspout does not need to be arranged. Then, the waterproof mortar material is brushed on the side of the rainwater bucket base module 23 or the non-rainwater bucket base module 13. After the brushing is completed, the side wall module 11 is divided into the left and right sides and the rainwater bucket base module 23 or the non-rainwater bucket base module 13 is bonded. After the bonding is completed, the waterproof mortar material is brushed on the joint position. After the brushing is completed and the waterproof mortar material is solidified, it is necessary to refer to the original design parameters for a water storage test to ensure that the waterproof and drainage performance of the overall system meets the requirements. After the water storage test is completed, the inner base of the drainage ditch is cleaned, and the connecting rod 12 is installed using the groove reserved in the side wall module 11. The length of the connecting rod is twice that of a single side wall module and it is installed in the center to ensure the stability of the overall system. After the installation is completed, the joints are coated with waterproof mortar material. The part of the connecting rod 12 protruding from the side wall groove can prevent the phenomenon of water backflow, further improving the water storage and drainage performance. Finally, the top cover module 14 is installed in the reserved L groove position of the side wall module 11 to achieve the complete installation of the drainage ditch.
