Description

Technical Field

[0001] This invention relates to the photovoltaic industry, and more specifically, to a photovoltaic construction system and method for highway slopes. Background Technology

[0002] As the photovoltaic industry expands deeper into distributed applications, idle land resources along highways are becoming a new source of photovoltaic construction. Slope areas, with their sunny slopes, offer the dual benefits of improved power generation efficiency and soil and water conservation through photovoltaic development, making them a key element in the "transportation + energy" integration model. Engineering practice shows that using micro-hole cast-in-place pile foundations, ensuring the support inclination angle matches the natural slope, maximizes the preservation of the original terrain structure and reduces earthwork volume.

[0003] Such foundations typically require deep holes and strict verticality to withstand structural risks from vibrations caused by traffic flow alongside highways. However, the unique topography of slope spaces restricts the application of traditional construction equipment: on the one hand, photovoltaic arrays need to be densely arranged along the contour lines of the slope to ensure the flatness of the components during installation; on the other hand, steep slopes and narrow working surfaces form natural barriers, making it impossible for conventional large drilling equipment to be parked stably and posing a risk of slippage and overturning.

[0004] Current slope photovoltaic construction faces three core contradictions: First, safety and efficiency are difficult to balance. The slope is adjacent to the emergency lane of a highway, and the vibration load caused by traffic requires a more conservative foundation design, necessitating deeper and deeper boreholes than projects on flat ground. However, manual drilling is inefficient and prone to inaccurate verticality control, while the lateral movement of heavy machinery on the slope can easily damage slope stability and cause equipment falls. Second, the precision control chain is broken. From borehole positioning and drilling verticality to the installation of embedded parts, each link lacks systematic precision assurance measures, leading to quality defects such as misalignment of components and uneven exposed purlin lengths during subsequent support installation, affecting the overall structural reliability. Third, concrete pouring technology is limited. Due to the slope, conventional concrete transport equipment cannot approach the work surface, and using a pumping solution faces increased costs and the problem of easy pipeline blockage.

[0005] Existing improvement solutions, such as erecting a full-span scaffolding platform, can provide a working surface, but they have drawbacks such as long construction period, high cost and damage to slope vegetation; while simple sliding rail devices, due to the lack of horizontal adjustment and anti-slip mechanism, still cannot solve the problems of stable movement of drilling rigs and accurate hole drilling. Summary of the Invention

[0006] To overcome the shortcomings of the existing technologies, this invention provides a photovoltaic construction system and method for highway slopes. This development is a specialized construction equipment and method for photovoltaic projects on highway slopes, combining slope adaptability, high construction efficiency, and precise control throughout the entire process. It achieves high-quality and rapid construction of cast-in-place pile foundations while ensuring zero disturbance to the slope's geological structure. This development fundamentally solves the problem of low work efficiency and can significantly improve the utilization rate and work efficiency of highway slopes.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A photovoltaic construction system for highway slopes includes a walkway assembly, a planar support unit, diagonal supports, a vertical support assembly, and a traction assembly. Two sets of walkway assemblies are arranged in parallel. Each walkway assembly includes a splicing beam. The planar support unit includes a support beam, which is welded to the lower surface of the splicing beam. The support beam and the splicing beam together form the surface frame of the platform. The vertical support assembly is vertically connected to the lower, open end of the support beam. The diagonal supports are inclined, with one end connected to the upper part of the vertical support assembly and the other end connected to the lower surface of the planar support unit. The traction assembly is positioned above one side of the walkway assembly to enhance the stability of the platform and the drilling machine.

[0008] The walkway assembly also includes threaded steel bars, connecting bolts, and simple guardrails. Multiple sets of splicing beams are connected by connecting bolts to form a track frame. The threaded steel bars are welded laterally to the upper surface of the splicing beams to provide friction for the drilling machine to prevent slippage. The simple guardrails are set on the outside of the track frame to prevent falls.

[0009] The planar support unit also includes a horizontal bubble meter, which is located in the middle of the upper surface of the support beam to detect the horizontal status of the platform in real time.

[0010] The vertical support assembly includes an outer sleeve, an inner sleeve, a quick-locking device, and an anti-slip pad. The outer sleeve is disposed on the lower surface of the support beam, the inner sleeve is movably inserted into the outer sleeve, the quick-locking device is disposed at the insertion hole of the inner sleeve and the outer sleeve, and is used to adjust the height of the vertical support assembly, and the anti-slip pad is disposed at the bottom of the inner sleeve.

[0011] The traction assembly includes a platform winch, a drilling machine winch, and a traction wire rope. The platform winch is fixed to the upper edge of the walkway assembly, the drilling machine winch is installed at the tail of the drilling machine, and one end of the traction wire rope is anchored to the top of the slope, while the other end connects the platform winch and the drilling machine winch.

[0012] The platform winch and drilling machine winch can automatically tighten and loosen.

[0013] The splicing beams, simple guardrails, support beams, diagonal supports, outer sleeves, and inner sleeves are all made of steel.

[0014] A construction method for a photovoltaic system on a highway slope includes the following steps. S1. Positioning and layout: Determine the drilling points based on the coordinates of the design drawings and the curvature of the slope on site. Mark the points with markers. After completion, check the points by pulling lines to ensure that the points in the same group are on a straight line and that the upper and lower guide lines of the two adjacent groups intersect at the center. S2. Drilling: Place at least two drilling platforms according to the location of the points in the same row. The drilling platforms are used alternately. Adjust the extension height of the vertical support component according to the slope. Confirm that the track is in a horizontal position using a level bubble meter. Use the traction steel wire rope of the traction component to fix the drilling machine and drilling platform to the anchor point at the top of the slope. The drilling machine travels to the point on the walkway component. After measuring and adjusting the verticality of the drill rod to meet the requirements, drill the hole. Clean the loose soil in the hole and compact it. S3. Installation and pouring of embedded parts: After cleaning the loose soil at the bottom of the hole, place the embedded parts in the center of the grouting hole, adjust the orientation of the installation holes on the embedded parts, ensure that the position and height of the embedded parts are consistent, calibrate the elevation with a level, monitor the verticality with a dual-axis tilt sensor, make fine adjustments if there is a deviation, use a concrete truck on the upper part of the slope to transport concrete to the grouting hole through a chute, and control the verticality of the embedded parts. S4. Bracket Installation: Clean the embedded parts and apply an anti-rust coating. Install the columns into the embedded parts, adjust the column height, connect and fix the main beam to the columns, and make the inclination angle of the main beam consistent with the slope. Adjust the top screws of the embedded parts and measure to ensure that the columns are vertical at 90° before tightening. Install the purlins on the purlin brackets, clean the purlin brackets and apply coupling agent. Use positioning plates to ensure spacing. Measure the exposed length of the main beam to ensure that the exposed lengths at both ends of the main beam are consistent. S5. Before installing photovoltaic modules, measure the length of the module protruding from the purlin according to the drawing requirements. First, install the two modules on the same side of the same row, and then install the middle modules one by one. Measure the gap every 3 modules. After installation, pull a line to control the length of the lower edge of the module protruding. After the middle part of the modules is installed, check for any misalignment and the flatness of the upper and lower edges of the modules.

[0015] In step S2, the anchoring point at the top of the slope is a steel pile or anchor rod driven into the ground.

[0016] In step S2, the deviation of the hole center is measured by pulling a line between adjacent holes.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention systematically solves the problems of stability, accuracy, and efficiency in the construction of photovoltaic foundations on highway slopes through the synergistic innovation of modular platform structure and refined construction methods.

[0018] At the structural level, a multi-stage stabilization system based on plug-in adjustable vertical support components enables the drilling platform to dynamically adapt to complex slopes: the vertical support components, through a stepless telescopic locking mechanism between the inner and outer sleeves, combined with the friction-enhancing design of the bottom anti-slip pads, ensure that the platform maintains a horizontal working surface even in steep slope environments; while the inclined diagonal supports and planar support units form a shear-resistant triangular truss, effectively dispersing the lateral loads during equipment operation and significantly reducing the risk of disturbance to the slope soil. The traction component's unique dual-winch anchoring system, through independent control of the tension ratio between the platform winch and the drilling machine winch, can maintain the system's anti-slip safety margin even under traffic vibration conditions.

[0019] At the construction method level, an innovative full-process precision control chain was constructed: the through-line intersection positioning method was used to ensure the precise spatial topological relationship of the holes, enabling the upper and lower rows of embedded parts of adjacent photovoltaic arrays to form conjugate alignment; combined with real-time leveling feedback from the horizontal bubble meter and the alternating progressive construction of dual platforms, stringent standards of small drilling verticality error and minimal hole center deviation were achieved. Particularly noteworthy is the concrete directional conveying process based on corrugated pipe chutes, which, while avoiding the risk of pump blockage, ensured the controllability of the verticality of the embedded parts in the vibration environment. Finally, during the support installation stage, the misalignment of the photovoltaic module arrangement was completely eliminated through the mirror matching design of the main beam inclination angle and slope, and the millimeter-level control of the exposed purlin length.

[0020] Compared to traditional solutions, this technology creatively integrates the slope adaptability of adjustable outriggers, the dynamic balance control of the traction system, and the geometric constraint mechanism of construction precision. While ensuring zero ecological damage to the slope, it improves drilling efficiency and significantly reduces the frequency of traffic control due to rework, providing highly reliable technical support for the "transportation + energy" integration model.

After completion, check the points by pulling lines to ensure that the points in the same group are on a straight line and that the upper and lower guide lines of the two adjacent groups intersect at the center.

Install the purlins on the purlin brackets, clean the purlin brackets and apply coupling agent. Use positioning plates to ensure spacing. Measure the exposed length of the main beam to ensure that the exposed lengths at both ends of the main beam are consistent. S5. Before installing photovoltaic modules, measure the length of the module protruding from the purlin according to the drawing requirements. First, install the two modules on the same side of the same row, and then install the middle modules one by one. Measure the gap every 3 modules. After installation, pull a line to control the length of the lower edge of the module protruding. After the middle part of the modules is installed, check for any misalignment and the flatness of the upper and lower edges of the modules.

[0032] Preferably, in step S2, the anchoring point at the top of the slope is a steel pile or anchor rod driven into the ground.

[0033] Preferably, in step S2, the deviation of the hole center is measured by pulling a line between adjacent holes.

[0034] During the drilling platform erection phase, the splicing beams 101 are assembled into a parallel track frame using connecting bolts 103, with the track spacing adjusted according to the width of the drilling machine tracks. Threaded steel bars 102 are uniformly welded laterally onto the upper surface of the splicing beams 101 to form anti-slip patterns. Simple guardrails 104 are installed on both sides of the track, with guardrail posts inserted into pre-set sleeves and locked. Support beams 201 are horizontally welded between the lower surfaces of the two sets of splicing beams 101. A horizontal bubble level 202 is installed in the middle of the upper surface of the support beam 201 and secured with bolts. The outer sleeve 401 is vertically welded to the lower surface of the support beam 201 away from the slope, with the inner sleeve 402 inserted into the outer sleeve 401. The length is calculated according to the slope, and the height is locked using a quick-locking device 403, ensuring the anti-slip pad is firmly in contact with the slope. One end of the inclined support 3 is hinged to the lower surface of the support beam 201, and the other end is hinged to the top of the vertical support assembly 4. After adjusting the inclination angle, the hinge bolts are locked. The platform winch 501 is bolted to the end of the walkway assembly 1 on the uphill side.

[0035] After the platform is installed, the operator places the points according to the coordinates on the drawing, and pulls nylon lines between the holes in the same row to ensure that the three points of the markers are aligned.

The embedded parts are hoisted into the center of the hole, and the through holes are adjusted to face the top of the slope. A line is used to level the top of the embedded parts in the same row, ensuring uniform exposed height across the rows. Concrete is poured into the hole through a φ300 corrugated pipe chute, and vibrated simultaneously with pouring. A slope gauge is used to monitor verticality against the embedded parts. The front and rear columns are inserted into the embedded parts, and a tape measure is used to ensure a uniform exposed 500mm. The main beam is connected to the columns, and an angle gauge is used to calibrate the main beam's inclination angle to match the slope. The verticality of the columns is adjusted by tightening the anchor screws of the embedded parts, and the connecting bolts are tightened. After the purlins are assembled on the ground, they are placed on the purlin supports, and a tape measure is used to ensure uniform exposed length at both ends of the main beam. Before component installation, the exposed length of the components is measured according to the drawings. The two pieces on the edge of the same row are installed first. After installation, a line is used to control the extended length of the lower edge of the components. After the middle components are installed, any misalignment is checked, and the flatness of the upper and lower edges of the components is verified.
