Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a construction method for high-resistant bamboo and anti-corrosion wood irregular paving. Background Technology

[0002] High-durability bamboo preservative-treated wood is widely used as a green and environmentally friendly paving material in residential, hotel, outdoor landscaping, decoration and renovation fields. Flooring made of high-durability bamboo preservative-treated wood has also become a popular outdoor flooring choice for consumers in recent years. High-durability bamboo preservative-treated wood not only has good practicality, but also has high ornamental value.

[0003] High-durability bamboo-based preservative-treated wood has a stability and strength far exceeding that of ordinary preservative-treated wood. After installation, it surpasses ordinary preservative-treated wood in terms of landscape effect, integrity, and feel underfoot. All materials are environmentally friendly and do not harm the environment, thus increasing landscape and environmental benefits.

[0004] However, due to the high density of high-resistant bamboo preservative-treated wood, the cutting difficulty is relatively high, the shaping and irregular construction process is relatively complex, the construction efficiency is low, and the construction cost is high, which makes the construction of high-resistant bamboo preservative-treated wood in irregular shapes quite difficult. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a construction method for irregularly shaped bamboo-based anti-corrosion wood paving.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a construction method for special-shaped paving of high-resistant bamboo and anti-corrosion wood, comprising the following steps in sequence: site leveling and compaction, foundation cleaning, positioning and layout, keel fabrication and installation, installation of high-resistant bamboo and anti-corrosion wood, and edge cleaning. A BIM modeling step is added before the site leveling and compaction begins. Between the site leveling and compaction and foundation cleaning steps, three steps are added in sequence: paving area positioning and layout, spreading of lime-soil bedding layer, and laying of concrete layer. In the keel fabrication and installation steps, the keel is placed according to the positioning line, and the keel is fixed on one side with bolts. For keels with curvature, a cutting machine is used to cut slits and then the keel is bent in the direction of the slits. The number of slits is one or more until the shape of the keel is consistent with the positioning line. The installation steps of the high-resistance bamboo preservative-treated wood include: pre-arranging the laying method of the high-resistance bamboo preservative-treated wood paving on the BIM according to the shape and specifications of the high-resistance bamboo preservative-treated wood paving, calculating the shape and quantity of the high-resistance bamboo preservative-treated wood that needs to be cut; and then cutting the high-resistance bamboo preservative-treated wood that needs to be cut.

[0007] As a preferred method, BIM modeling includes the following steps: before construction begins, use computer software BIM to simulate the layout based on the construction drawings, create a three-dimensional graphic, and check whether the dimensions and elevations of the drawing are accurate.

[0008] Preferably, the keel fabrication and installation steps include h1: selecting the initial cut position of the keel; h2: Use a cutting machine to cut one-third of the width of the keel, with a cut width between 2 and 3 millimeters; bend the keel towards the cut until the cut width is 1 millimeter and then stop bending; h3: Determine if the shape of the keel is consistent with the positioning line. If the shape of the keel is inconsistent with the positioning line, select a new cutting position. The distance between adjacent cutting positions should be greater than 0.5 meters. h4: Repeat steps h2 and h3 until the keel shape matches the positioning line; h5: Fix the keel to the concrete foundation with angle iron and bolts, with the angle iron located in the center of two adjacent cuts.

[0009] As a preferred option, when adjusting the relative position of the keel and the positioning line, do not tighten the bolts. Tighten the bolts only after the keel has been adjusted correctly.

[0010] As a preferred option, after the keel is installed, the cut areas should be treated with anti-corrosion coating by brushing on anti-rust paint.

[0011] As a preferred option, the planar control for the paving area positioning and layout is implemented in three levels, including b1: the first level is the control points handed over by Party A, which serve as the basis for measurement control in this section; b2: The second level is to determine the location of the main axis and to densify the permanent control stakes around it; b3: The third level defines the plane control grid of the paving area, which directly guides the construction surveying and detailed layout work.

[0012] As a preferred option, the step of spreading the lime-soil cushion layer includes selecting silty clay, sieving the silty clay, using hydrated lime, and mixing the hydrated lime and silty clay evenly.

[0013] Preferably, the concrete layer laying step includes e1: construction preparation; according to the contour lines of the construction drawing, calculate the elevation of the intersection of the longitudinal and transverse axes, and verify the elevation of the graded crushed stone cushion layer; e2: Measurement and layout; according to the axis, make steel reinforcement elevation stakes on the site, mark the points on the steel reinforcement, and mark the height of the lower mark as the top surface of the concrete layer; e3: Lay the concrete layer; after verifying that the elevation is correct, lay the concrete sub-base layer by manual spreading, ensuring that the designed laying thickness is achieved during construction; e4: Curing; After the concrete layer is laid, cover it with a film for curing in a timely manner.

[0014] As a preferred method, the positioning and layout process includes the following steps: after calibrating the reference points using RTK, accurately place the coordinate points of the keel on the concrete foundation and mark them with ink lines. Based on the planar dimensions of the concrete foundation surface, center, square, divide, and position the grid lines to form a positioning grid.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows: (1) The high-durability bamboo anticorrosive wood paving pattern is laid out in advance using BIM, especially the curved positions at the corners, which ensures that the cut high-durability bamboo anticorrosive wood is beautiful while maximizing the utilization of the cut material, thus greatly reducing the material loss rate. (2) After BIM layout, the keel is bent by cutting the keel to make the keel into any shape. This successfully overcomes the difficulties and common quality problems in the irregular paving of high-resistant bamboo anticorrosive wood, such as multiple arcs and inconsistent angles and arcs. It ensures the design effect and construction specifications, saves costs for subsequent maintenance. The production and installation of the keel eliminates the operation of the pipe bending machine, saving economic costs. The production of the keel saves energy consumption, thereby reducing environmental pollution. (3) High-durability bamboo preservative wood has a long service life, which is 3 to 5 times that of ordinary preservative wood, but the unit price is about 2 to 3 times. From the perspective of long-term benefits, it reduces material costs. At the same time, by optimizing the layout of the high-durability bamboo surface layer, materials are saved, further saving material costs. The maintenance cost of high-durability bamboo preservative wood is low. Ordinary preservative wood generally needs maintenance once every 2 to 3 years, while high-durability bamboo preservative wood generally needs maintenance once every 5 years, thus reducing maintenance costs. (4) Between the two steps of site leveling and compaction and foundation cleaning, three steps are added in sequence: paving area positioning and layout, spreading of lime-soil bedding layer and laying of concrete layer. This ensures that even in the field with more complex road conditions, high-resistant bamboo anticorrosive wood can be laid smoothly, and the standardization is higher. Attached Figure Description

[0016] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below: Figure 1 A flowchart illustrating the construction method for irregularly shaped bamboo and anti-corrosion wood paving. Detailed Implementation

[0017] To better understand the above-mentioned objectives, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example The following is combined with Figure 1 Specific explanations, such as Figure 1 As shown, a construction method for high-resistant bamboo anticorrosive wood irregular paving includes site leveling and compaction, foundation cleaning, positioning and layout, keel fabrication and installation, high-resistant bamboo anticorrosive wood installation and edge cleaning. A BIM modeling step is added before the site leveling and compaction begins. Between the site leveling and compaction and foundation cleaning steps, three steps are added in sequence: paving area positioning and layout, spreading of lime-soil bedding layer and laying of concrete layer.

[0020] In the keel fabrication and installation process, the keel is placed according to the positioning line and fixed on one side with bolts. For keels with curvature, a cutting machine is used to cut slits and then the keel is bent in the direction of the slits. The number of slits is one or more until the shape of the keel is consistent with the positioning line.

[0021] The installation steps for high-resistance bamboo preservative-treated wood include: pre-arranging the laying method of high-resistance bamboo preservative-treated wood on BIM according to the shape and specifications of the high-resistance bamboo preservative-treated wood paving, calculating the shape and quantity of high-resistance bamboo preservative-treated wood that needs to be cut; and then cutting the high-resistance bamboo preservative-treated wood that needs to be cut.

[0022] When adjusting the relative position of the keel and the positioning line, do not tighten the bolts. Tighten the bolts only after the keel has been adjusted correctly.

[0023] After the keel is installed, the cut areas should be treated with anti-corrosion paint.

[0024] The steps for spreading the lime-soil subbase include selecting silty clay, sieving the silty clay, using hydrated lime, and mixing the hydrated lime and silty clay evenly.

[0025] Step A: BIM modeling includes the following steps: Before construction begins, use computer software BIM to simulate the layout based on the construction drawings, create a 3D graphic, check the accuracy of the dimensions and elevations of the drawing, and use it to guide the on-site positioning and layout after verification; use BIM to lay out the high-durability bamboo anticorrosive wood paving style in advance, especially at curved corners, to ensure aesthetic appeal while maximizing the utilization of cut materials, thus greatly reducing material waste.

[0026] Step B: Locating and laying out the paving area; determine the plane control grid of the paving area to directly guide the positioning and laying out.

[0027] More specifically, in step B, the plane control is implemented in three levels, including b1: the first level is the control point handed over by Party A, which serves as the basis for measurement control in this section; b2: The second level is to determine the location of the main axis and to densify the permanent control stakes around it; b3: The third level defines the planar control grid of the paving area, which directly guides the construction surveying and detailed layout work. If necessary, the longitudinal and transverse mesh joints of the paving material are defined within the grid to meet the paving requirements.

[0028] The three-level implementation of planar control ensured that the planar position and elevation of the paving met the design requirements of the drawings and achieved excellent standards.

[0029] Step C: Site leveling and compaction; The site is leveled mechanically, and then compacted with a road roller. Areas that the road roller cannot reach are compacted manually with a rammer. The degree of compaction is tested with testing instruments to ensure that the degree of compaction of each layer meets the design requirements.

[0030] In step C, elevation control steel piles are set at 10-meter intervals to strictly control the elevation, and 200 mm of soil is reserved for manual clearing to the design elevation.

[0031] Step D: Spread the lime-soil bedding layer; select silty clay, sieve the silty clay, use slaked lime, and mix the slaked lime and silty clay evenly; After sieving, the silty clay particles should be no larger than 15 mm, and the hydrated lime particles should be no larger than 5 mm. The hydrated lime and silty clay should be mixed evenly in a ratio of 3:7.

[0032] Strictly control the design elevation during paving. In step D, leave a loose paving thickness during paving to ensure that the elevation meets the design requirements after compaction. Compact as you pave, and there should be no areas that are not compacted. The loose paving thickness is also known as the loose paving thickness, which is the paving thickness of the fill material before compaction.

[0033] Step E: Lay the concrete layer.

[0034] Step E includes e1: construction preparation; according to the contour lines of the construction drawings, calculate the elevation of the intersection of the longitudinal and transverse axes, and verify the elevation of the graded crushed stone cushion layer; e2: Measurement and layout; the surveyor determines the axis, sets up the steel reinforcement elevation stakes on the site, marks the points on the steel reinforcement, and sets the height of the lower mark to the top surface of the concrete layer. e3: Lay the concrete layer; after verifying that the elevation is correct, lay the concrete base layer. When the concrete arrives at the construction site, each batch of concrete must be inspected. Only after passing the inspection can it be used. The concrete is spread manually, and the designed laying thickness must be achieved during construction. e4: Curing; After the concrete layer is laid, cover it with a film in a timely manner for curing. During the curing period, no vehicles are allowed to drive on the concrete layer.

[0035] Step F: Foundation cleaning; Before the installation of high-resistant bamboo anticorrosive wood paving, remove the mud, mortar and garbage from the surface of the concrete layer, rinse with water and let it dry, grind the concrete base to ensure that the overall horizontal plane is consistent after installation. Step G: Positioning and layout; After calibrating the reference points with RTK, accurately place the coordinate points of the keel on the concrete foundation and mark them with ink lines. Based on the plane dimensions of the concrete foundation surface, find the center, square, divide, and position the grid lines to form a positioning grid.

[0036] Step H: Keel fabrication and installation; Place the keel according to the positioning lines marked on the positioning line. The length of the keel must match the dimensions of the positioning line. Fix the keel with bolts on one side. For keels with curvature, cut slits with a cutting machine and then manually bend them in the cutting direction. If bending is still required, add another slit. Continue in this manner until the shape of the keel matches the positioning line.

[0037] Step H includes h1: Selecting the initial incision location for the keel; h2: Use a cutting machine to cut one-third of the width of the keel, with a cut width between 2 and 3 millimeters; bend the keel towards the cut until the cut width is 1 millimeter and then stop bending; h3: Determine if the shape of the keel is consistent with the positioning line. If the shape of the keel is inconsistent with the positioning line, select a new incision position. The distance between adjacent incision positions should be greater than 0.5 meters to avoid breaking the keel during bending and affecting the strength of the keel. h4: Repeat steps h1 and h2 until the keel shape matches the positioning line; h5: Fix the keel to the concrete foundation with angle iron and bolts, with the angle iron located in the center of two adjacent cuts.

[0038] Fix the keel to the concrete foundation with angle iron and bolts. When adjusting the relative position of the keel and the positioning line, do not tighten the bolts. Tighten the bolts after the keel is adjusted to be correct.

[0039] After the keel is installed, the cut areas should be treated with anti-corrosion coating by applying 1 to 3 coats of anti-rust paint.

[0040] Step 1: Installation of high-durability bamboo anticorrosive wood.

[0041] Step I includes I1: Based on the shape and specifications of the high-resistant bamboo anticorrosive wood paving, pre-arrange the paving method of the high-resistant bamboo anticorrosive wood paving on the BIM, and calculate the shape and quantity of the high-resistant bamboo anticorrosive wood that needs to be cut. I2: Cut the high-quality bamboo-resistant and anti-corrosion wood that needs to be cut; I3: Secure the metal fastener to the keel, slide the first piece of high-resistant bamboo anti-corrosion wood into the metal fastener, then slide the second piece of high-resistant bamboo anti-corrosion wood into the metal fastener, and so on; I4: Slide the metal fastener into the other end of the high-resistance bamboo anticorrosive wood and fix the metal fastener to the keel; I5: Side panel, secured with metal fasteners.

[0042] A keel is a building material used to support the shape and fix the structure.

[0043] Step J: Edge finishing and cleaning; cut smooth arcs on both sides of the paved high-durability bamboo anticorrosive wood, and clean up debris and sanitation in the paved area after finishing the edges.

[0044] By bending the steel through the cuts, steel pipes can be made into any shape, thus realizing the production of irregular keels, maximizing the use of the keel and adapting to various construction environments.

[0045] The layout and cutting principles of high-resistance bamboo preservative-treated wood: First, BIM is used for layout. Straight and curved cuts of the anti-corrosion wood are made at the corners. Through meticulous layout, the cut materials are utilized to the maximum extent, greatly reducing the material loss rate. Combined with irregular keel, strips of anti-corrosion wood are used to pave a curved and natural garden path.

[0046] RTK is a differential method for processing carrier phase observations from two measurement stations in real time. RTK is a measurement method that can obtain centimeter-level positioning accuracy in real time in the field, bringing new measurement principles and methods to engineering layout, topographic mapping, and various control surveys, and greatly improving work efficiency.

[0047] To control the construction quality of the keel, accurate layout is required. First, the coordinates on the drawings are marked in detail, with a coordinate point marked every 5 meters and a coordinate point every 0.5 meters at turns to ensure the smoothness of the curves. After calibrating the reference points with RTK, each coordinate point is accurately placed on the concrete foundation and marked with ink lines.

[0048] To control the installation quality of the preservative-treated wood, the fasteners for the high-resistance bamboo preservative-treated wood must be inspected and selected, and deformed metal fasteners must be removed; the position of the fasteners fixed to the keel must be accurately checked to ensure that the gaps between the high-resistance bamboo preservative-treated wood pieces are uniform; the high-resistance bamboo preservative-treated wood must be cut strictly according to the layout drawing, with the error controlled between 1 mm and 2 mm; the spacing between two pieces of high-resistance bamboo preservative-treated wood must be controlled at 5 mm.

[0049] All holes and cut surfaces must be coated with protective paint in a timely manner to prevent rainwater from entering.

[0050] During the material cutting process, silent saw blades are selected, and mist cannons are used throughout the construction process to suppress dust and ensure that no dust is generated.

[0051] Graded crushed stone cushion layer is a mixture of aggregates of various sizes.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
