Technical Field
[0001] The present invention relates to a building structure, and in particular to a modular construction method for a steel structure plank road for a garden landscape in a complex terrain. Background Art
[0002] The burgeoning tourism economy is increasingly becoming a form of leisure, driving the prosperity of the smokeless industry. Mountain resources are like tapping into a treasure trove, and their development and utilization have become a key focus of green development. For tourist destinations, the more complex the mountainous terrain and the more majestic and beautiful the natural scenery, the more attractive they are to tourists. As essential tourism infrastructure, scenic plank roads play a central role and form the foundation for the development of tourism resources.
[0003] Plank roads have been a major transportation route since ancient times, evolving from hand-hewn paths to those constructed with wood and stone. Modern landscape plank road construction often relies heavily on concrete for filling. This traditional structure and construction method can easily pollute the natural environment. The cement component in concrete consumes significant amounts of coal during production, releasing significant amounts of carbon dioxide greenhouse gases, and the aggregate is a non-renewable resource. Summary of the Invention
[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a novel modular construction method for a steel structure plank road for garden landscapes in complex terrain. The steel structure plank road for garden landscapes in complex terrain proposed by the present invention and its construction method can adapt to different mountain terrains, and the integrated modular installation and construction greatly improves the installation efficiency and adaptability, and has good stability and a more outstanding landscape.
[0005] In order to achieve the above-mentioned invention purpose, the technical solution provided by the present invention is as follows:
[0006] A modular construction method for a steel structure plank road for garden landscapes on complex mountainous terrain. The garden landscape steel structure plank roads include three types: wooden plank roads, mountain plank roads, and ladder plank roads. The wooden plank roads are short mountain trails, the mountain plank roads are forest trails with platform walkways and steps, and the ladder mountain roads are winding forest trails along the mountain. The modular construction method includes on-site production and modular installation.
[0007] The first step is to formulate the construction process of the garden landscape steel structure plank road according to the construction drawings and construction conditions, and divide it into different modules according to the types of wooden plank roads, mountain plank roads and ladder plank roads, and number each module, and issue a structural dimension drawing for each module;
[0008] Second step, in the complex terrain mountain, according to the planned garden landscape stack road line, the specific position of wood stack road, up mountain stack road and ladder stack road is drawn respectively, which involves the installation position and installation size of each module, and the foundation excavation, arrangement of foundation steel, pouring of foundation concrete and cushion concrete are carried out at each installation position, and the embedded parts are placed in the concrete;
[0009] Third step, a module manufacturing site is set at the foot of the complex terrain mountain, and the modules are processed and manufactured according to the structural size diagram of the modules, which includes main beams, steps, platforms and guardrails;
[0010] Fourth step, the main beams are installed on the concrete foundation of the planned route of the complex terrain mountain, and the rising stack foundation is formed by two main beams, after the installation of the main beams, the modular steps and platforms are transported to the corresponding positions according to the number after the detection of the size;
[0011] Fifth step, the steps and platforms are installed on the main beams in two directions from top to bottom and from bottom to top by using multi-section simultaneous construction;
[0012] Sixth step, the guardrails are installed on the installed steps and platforms.
[0013] In the first step, the above three types of wood stack road, up mountain stack road and ladder stack road are different names marked in the design diagram for different positions, the wood stack road is a small section of mountain path from the flower field to the slide, and the structure form is: concrete double connected pier foundation→steel support→steel beam→step, resting platform→rot-resistant wood or plastic wood facing→left and right guardrails; The up mountain stack road refers to the relatively long platform walkway plus ladder steps in the forest from the observation elevator outlet to the top of the mountain, and the structure form is: concrete independent pier foundation→welded steel beam with embedded parts→step, resting platform with steel support→rot-resistant wood or plastic wood facing→guardrail outside the flat section, left and right guardrails at the step; The ladder stack road is a winding path in the forest from the rest service hall to the top of the mountain, and the structure form is: continuous beam foundation along the mountain→embedded parts every 1500mm during pouring→steel support→steel beam→step, resting platform→rot-resistant wood or facing→guardrail along the outside edge of the mountain.
[0014] In the second step, the construction preparation includes measurement positioning, coordinate measurement and level point measurement, and the wire coordinate level point network is laid out.
[0015] In the second step, when pouring concrete, the free fall height of the concrete should not exceed 2m; the vibrator should be operated with "fast insertion and slow withdrawal" to prevent stratification and segregation; the vibration time should be controlled, generally 20-30S per point, and the vibration should be stopped when no bubbles appear on the surface of the concrete and mortar appears; the vibrating rods should be inserted evenly and staggered at intervals of 30-40cm, and moved in sequence to prevent vibration leakage, and the distance between the vibrating rods and the formwork should not exceed 15cm to avoid collision with the steel bars and formwork; after the concrete is poured, tap the formwork lightly with a small wooden hammer to check the density of the concrete pouring and prevent the appearance of honeycombed surfaces and dog holes.
[0016] Before starting construction, according to the design regulations and construction requirements, the route direction and intersection position shall be re-surveyed and checked, specifically the centerline measurement and horizontal measurement. The centerline measurement shall be carried out on the route. If the original measuring pile is lost or tilted, it shall be corrected by adding nails. For the main direction piles, side piles shall be set outside the edge of the road surface, and side pile records shall be drawn to check the elevation of the leveling point. If the leveling point is far away from the construction road, a temporary leveling point shall be set at the construction site. When the leveling point is measured, it must be closed and checked. The horizontal measurement shall be observed together with the left and right side piles according to the pile number, and records shall be made separately to draw a cross-sectional view.
[0017] In the third step, a processing fence is set up in a larger site at the foot of the mountain, and steel beams, step steel frames, and segmented railings are prefabricated. They are then transported to the construction section by manpower and installed in sections from the bottom up. It is agreed that the number of steps will be set according to the slope of the terrain during construction. When the top step reaches the safety height specification and design requirements from the ground, a rest platform will be set. When setting up the rest platform, it will be extended at a 6% slope to the starting point of the previous step, and so on until the top of the mountain. Single-step step modules and segmented platform steel beams are prefabricated. Fourth, segmented railings are made according to the slope and length of the steps and platforms, and then transported to the construction site for installation.
[0018] The third step also includes anti-corrosion and fireproofing treatment of the installed steel beams and columns. The specific painting procedures include surface purification, shot blasting and rust removal, surface roughness control, and high-pressure spraying of water-based inorganic zinc-rich primer. Among them, the time interval between sandblasting and rust removal and primer spraying shall not be greater than 3 hours.
[0019] After the steel structure is completed and the backfill around the foundation is compacted, paving the steel structure with teak antiseptic wood according to the drawing requirements, fixing the wood board with round head screws, and fixing the side board decoration with round head screws on the side;
[0020] After the keel and wooden panels are completed, the construction of the railings begins. The railings and wooden boards are fixed with bolts, the U-shaped galvanized steel plates and channel steels are fully welded, and the square timber columns and beams are fixed with galvanized bolts and angle steels.
[0021] Paint the wooden panels and railings, and the paint should be applied evenly, with a consistent and bright color, without obvious wrinkles, drips or bubbles.
[0022] Based on the above technical solution, the present invention has the following technical advantages compared with the existing technology:
[0023] 1. The garden landscape steel structure plank road of the present invention adopts square steel instead of concrete construction to reduce the amount of concrete used. The construction method of the traditional plank road is easy to cause pollution to the original ecological environment during the construction process. The cement component in the concrete consumes a lot of coal resources and releases a lot of carbon dioxide greenhouse gas during the production process. In addition, the aggregate is a non-renewable resource. This technology uses recyclable steel instead of sand and gravel to reduce the use of traditional cementitious materials, which is beneficial to saving resources and energy and protecting the ecological environment.
[0024] 2. The garden landscape steel structure of the present invention is mainly installed and constructed in the form of steel structure modules. Through the analysis of complex mountain terrain, three types of wooden plank roads, mountain plank roads and ladder plank roads are summarized. They can be selected and applied according to different terrain conditions. Moreover, the modules can be processed and produced on the construction site. By setting the foundation concrete and embedded parts and welding the steel beams to form a universal base form, different modules are installed on the base to form a continuous steel structure plank road.
[0025] 3. The garden landscape steel structure of the present invention utilizes concrete plus embedded parts to construct the foundation surface, and then installs steel beams to form the overall outline. The modular steps and platforms are then installed on the steel beams, and the installation can be operated from both bottom-up and top-down directions, which greatly improves the efficiency of installation and construction. In addition, in order to improve production efficiency, the module production site is also placed on a flat construction site at the foot of the mountain, which improves the targeted construction, facilitates the precision control of processing and construction, and greatly reduces logistics costs.

[0030] The following is a further detailed description of the modular construction method of a steel structure plank road for complex terrain mountain landscape in conjunction with the accompanying drawings and specific embodiments, in order to more clearly understand its structural composition and working mode, but this does not limit the scope of protection of the present invention.
[0031] The present invention provides a modular construction method for a steel-structured landscape plank road in complex mountain terrain. The vegetation and trees growing on the complex terrain create a natural landscape, allowing tourists to hike and enjoy the unique scenery of nature. Complex terrain includes at least conventional mountain trails that meet walking requirements and are not too long or steep; relatively flat platform trails; forest trails with a small drop and a few steps; and winding forest trails carved along the mountain.
[0032] Example 1
[0033] The Moshixin Valley project starts from Yangang West Road in the south and ends at Xufu Square in the north. It is adjacent to the natural mountain of Moshixin Mountain in the east and west. It integrates an abandoned mine and surrounding natural resources, connects squares, facilities, greenways and other public facilities, and is planned to be built into a complex open park that integrates citizens' leisure, fitness, sightseeing and tours.
[0034] like Figure 2 、 Figure 3 and Figure 4 As a case study of rapid construction in Moxin Valley, this paper involved a modular construction method for a steel structure plank road in a complex mountain landscape. The steel structure plank road includes three types: a wooden plank road 2, a mountain plank road 3, and a ladder plank road 1. The modular construction method includes on-site production and modular installation.
[0035] The first step is to formulate the construction process of the garden landscape steel structure plank road according to the construction drawings and construction conditions, and divide it into different modules according to the types of wooden plank roads, mountain plank roads and ladder plank roads, and number each module, and issue a structural dimension drawing for each module;
[0036] The second step is to mark out the specific locations of the wooden plank road 2, the mountain plank road 3 and the ladder plank road 1 on the complex terrain according to the planned garden landscape plank road route. The specific installation position and installation size of each module are involved. At each installation location, the foundation is excavated, the foundation steel bars are arranged, and the foundation concrete and cushion concrete are poured. The embedded parts are placed in the concrete.
[0037] The third step was to set up a modular fabrication site in an open area at the foot of a complex mountain. The modules were then fabricated according to the module's structural dimensions. The modules included the main beam, steps, platform, and guardrails. The following preparations were made: First, materials: hot-dip galvanized rectangular steel pipes (50mm*50mm*5mm for the steps, 160mm*80mm*5mm for the main beam and supports), embedded 200mm*200mm*10mm steel plates, and painted with an anti-rust primer. Railing specifications: 1050mm high, 80mm*10mm steel columns, 70mm*10mm flat steel with handguards on top, 30mm*30mm*2mm galvanized square steel inner frame, and galvanized low-carbon steel wire mesh with a diameter of d3 and a 50mm spacing. Second, fabrication: The step steel frame was 1040mm long, 283mm wide, and 170-195mm high.
[0038] The fourth step is to install the main beam on the concrete foundation of the planned route of the complex terrain. The two main beams form the foundation of the ascending plank road. After the main beam is installed, the dimensions are checked and the modular steps and platforms are moved to the corresponding positions according to the numbers.
[0039] Step 5: Install the steps and platforms onto the main beams using multiple sections simultaneously in both the top-down and bottom-up directions.
[0040] Step 6: Install guardrails on the installed steps and platforms.
[0041] The aforementioned steel structure plank walkways include three types: wooden plank walkway 2, mountain plank walkway 3, and ladder plank walkway 1. These three types are designated by different names for different locations in the design drawings. Wooden plank walkway 2 is a short mountain trail leading up from Huadian to the slide. It is 1.2 meters wide, with an overall inclined length of approximately 25 meters and a height difference of approximately 6.5 meters. Its structure is as follows: a double-connected concrete pedestal foundation → steel supports → steel beams → steps and resting platforms → preservative wood or plastic wood veneer → guardrails on both sides. Mountain plank walkway 3 is a relatively long forest trail from the sightseeing elevator exit to the top of the mountain, with a platform walkway and steps. It is 2.4 meters wide and approximately 160 meters long, with a total height difference of approximately 25 meters. Its structure is as follows: an independent concrete pedestal foundation → pre-embedded welded steel beams → steps and resting platforms with steel supports → preservative wood or plastic wood veneer → guardrails on the outside of the flat section and on the left and right sides of the steps. Yunti Mountain Trail 2, a winding path through the forest that runs from the rest area to the summit, is 1.2 meters wide and approximately 380 meters long, with a total height difference of approximately 90 meters. This path was also one of the project's challenges. Its structure consists of a continuous concrete beam foundation along the mountainside, embedded components placed every 1500mm during pouring, steel supports, steel beams, steps and rest platforms, preservative wood or plastic wood cladding, and guardrails along the mountainside's outer edges.
[0042] When treating the installation location, excavation must begin with the following requirements: a. Excavation of the foundation pit must strictly follow the construction plan, and over-excavation is strictly prohibited. b. Materials must not be piled around the foundation pit. c. If significant soil displacement occurs during excavation, excavation must be stopped immediately, the cause analyzed, and effective measures implemented. d. Surface water around the pit must be promptly removed.
[0043] If a continuous ground beam exists, the excavation requirements are: the excavation depth at the trestle foundation is 700mm (foundation height 600mm, cushion height 100mm) and the width is 600mm. The foundation pit at the mountainside is roughened according to the requirements of the drawings.
[0044] Then the basic steel bar construction is carried out. The steel bar processing process is: material re-inspection and welding test → material mixing → straightening → rust removal → material cutting → butt welding → bending and forming → finished product stacking.
[0045] Before bar batching, a stakeout technician lays out the steel. When cold-drawing the steel bars, the cold-draw rate for Grade I bars should be no more than 4%, and for Grade II and III bars, no more than 1%. A steel cutting machine is used to cut the steel. Before cutting, the bars are inspected for correct batching and then cut. The finished steel bars are transported on the ground using a combination of flatbed trucks and manual labor. The foundation slab reinforcement is installed manually by tying the steel. Ties are tied at each intersection of the two rows of steel bars around the foundation slab mesh, with staggered ties in between. Wire buckles are placed in a figure-eight pattern at adjacent tying points to prevent deformation of the mesh due to tying along the seams.
[0046] During foundation concrete construction, an independent pouring platform should be set up around the foundation pit for concrete pouring. Before pouring concrete, check that the formwork, support reinforcement, embedded parts, etc. meet design and specification requirements, and that the pouring platform is securely installed. During concrete pouring, monitor weather conditions to avoid pouring concrete during thunderstorms. Prepare a water pump, plastic sheeting, and raincoat to protect against rain. During concrete pouring, the free fall height of the concrete should not exceed 2 meters. Operate the vibrator "quickly insert and slow withdraw" to prevent stratification and segregation. Control the vibration time, generally 20-30 seconds per point. Stop vibrating when no bubbles appear on the concrete surface and mortar appears. Insert the vibrating rods evenly and staggered at 30-40 cm intervals, moving them in sequence to prevent vibration leakage. The distance between the vibrating rods and the formwork should not exceed 15 cm to avoid collisions with reinforcement and formwork. After pouring, tap the formwork with a small wooden hammer to check the density of the concrete pouring and prevent the appearance of honeycombs and dog holes.
[0047] Continuous operation is required during the pouring of concrete foundation caps. After pouring, during the initial setting period of the concrete, timely check, review, and correct the reserved dowel positions based on the axis measured before concrete construction to ensure the quality of the upper reinforcement. During the concrete pouring process, strictly follow the regulations for sampling. During the construction of the foundation slab, timely vibration is required to avoid honeycombing and rough surfaces after the initial setting period of the concrete. Pay attention to the curing time, starting curing before the final setting of the concrete, generally 6-8 hours after pouring. After the concrete is poured and formed, pay attention to the temperature and humidity of the post-curing period to prevent excessive water loss, which will cause uneven shrinkage inside and outside the concrete and cause cracking of the concrete surface.
[0048] During the construction of the steel structure, a combination of manual chain-falling and installation is adopted. First, the axis of the concrete foundation and the elevation of the top surface of the foundation are verified. The steel columns are installed first, and after they are corrected and fixed (the concrete strength of the steel columns at the plank road reaches 75%), the steel beams are installed in sequence, adjusted as they are installed, and then installed and fixed.
[0049] Before installation, prepare an installation plan and component supply plan, and organize the construction. Plank column construction: Verify the column center and locate the axis. First, weld a 10mm thick x 150mm x 150mm steel base plate to the bottom of the steel column, and weld all four sides of the column. Steel components should be shipped with a factory certificate. Before installation, check and verify components according to the drawings. Components should be transported to the installation area according to the installation sequence. If possible, place components below the installation location to ensure ease of installation, without compromising installation.
[0050] The construction process of steel structure installation includes:
[0051] ①Steel column installation: After the plank road steel column is transported to its place, it needs to be fixed with steel supports. After the verticality, horizontality and elevation are adjusted to meet the requirements, it is welded to the embedded parts and fixed.
[0052] ② Steel beam installation: After the steel beam is installed on the column and verified, it is adjusted and corrected. After the steel beam is installed in place, it is fixed and welded. The slope of the steel beam is corrected during installation, and any deviation is corrected at any time.
[0053] The construction plan for wooden plank roads and wooden railings is as follows:
[0054] First, proceed with the wood panel construction. Once the steel structure is complete and the backfill around the foundation is compacted, lay 90*38 pineapple preservative wood on the steel structure according to the drawings. Secure the wood panels with round head screws. Also secure the decorative side panels with round head screws.
[0055] After the keel and wood panels are completed, the railing construction begins. The railing is fixed to the wood planks with bolts, and the U-shaped galvanized steel sheet is fully welded to the channel steel. M10 galvanized bolts and angle steel are used to secure the square timber columns to the beams.
[0056] The quality of the anti-corrosion paint applied to wooden panels and railings must meet national standards. The paint should be applied evenly, with a consistent, glossy color, free of noticeable wrinkles, dripping, or bubbles, and with good adhesion. Misapplication and omissions are prohibited. The wood's specifications must meet design requirements, and its quality must comply with current national standards. The wood must be dried, treated with insecticides, and treated with preservatives. Construction must be strictly in accordance with the construction drawings. The finished wood surface should be smooth, firm, and free of looseness, and clean, meeting acceptance standards.
[0057] A tourism infrastructure improvement project in a certain city is located in Moxin Mountain. The project primarily focuses on renovating the original ecological landscape, covering 60,343 square meters. This construction method was applied to a total length of approximately 500 meters. The steel structure plank road technology reduces the use of traditional concrete materials, conserving resources and energy while also contributing to ecological conservation. Replacing gravel with locally sourced soil contributes to the sustainable development of landscaped paths.
[0058] The construction speed is fast, and the construction period is shortened by one-third compared to traditional concrete construction, with good environmental protection effects. During the construction of steel structure plank roads, the amount of sand, stone and ash used is greatly reduced. The materials used are mainly green, recyclable or degradable materials. After demolition, most of the materials can be recycled, which has good economic benefits.
[0059] The garden landscape steel structure plank road of the present invention adopts square steel instead of concrete construction to reduce the amount of concrete used. The construction method of the traditional plank road is easy to cause pollution to the original ecological environment during the construction process. The cement component in the concrete consumes a large amount of coal resources and releases a large amount of carbon dioxide greenhouse gas during the production process, and the aggregate is a non-renewable resource. This technology uses recyclable steel instead of sand and gravel to reduce the use of traditional cementitious materials, which is beneficial to saving resources and energy and protecting the ecological environment.
[0060] Since the garden landscape steel structure is mainly installed and constructed in the form of steel structure modules, the three types of wooden plank roads, mountain plank roads and ladder plank roads are summarized to meet the construction needs of complex mountain terrain. Moreover, the modules can be processed and produced on the construction site. By setting the foundation concrete and embedded parts and welding the steel beams to form a universal base form, different modules are installed on the base to form a continuous steel structure plank road. During installation, the operation can be carried out from both bottom-up and top-down directions, which greatly improves the efficiency of installation and construction. In addition, in order to improve production efficiency, the module production site is also placed on the flat construction site at the foot of the mountain, which improves the targeted construction, facilitates the precision control of processing and construction, and greatly reduces logistics costs.
