Description

Technical Field

[0001] This utility model relates to the field of new energy mountain photovoltaic, specifically to an auxiliary device for setting up foundation points for mountain photovoltaic piles. Background Technology

[0002] Currently, spiral pile foundations are generally suitable for mountainous photovoltaic projects with soft soil. These foundations are driven into the soil using spiral drill rods, eliminating the need for concrete pouring and allowing for rapid construction. However, existing mountainous photovoltaic spiral pile construction typically uses traditional total stations or RTK machines to measure pile locations. During measurement, these methods are susceptible to terrain obstruction, leading to pile position deviations (>10mm) and insufficient measurement accuracy. Furthermore, current mountainous photovoltaic construction often cannot guarantee a fixed orientation, and the design of pile locations does not consider slope, directly arranging them on a plan and ignoring the impact of slope on pile spacing. In actual installation, the designed locations are simply applied to the slope, resulting in discrepancies between the actual and designed pile spacing. Since photovoltaic support structures are designed according to these spacings, this discrepancy leads to a mismatch between the designed and actual dimensions of the support structures, requiring secondary processing and increasing construction costs and difficulty.

[0003] This utility model mainly improves the construction site layout of photovoltaic foundations in mountainous areas, thereby eliminating the problem of increased spacing caused by the failure to consider slope in the design. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model primarily provides an auxiliary device for laying out foundation points for mountain photovoltaic systems. This device, combined with existing foundation laying techniques in mountain photovoltaic systems, assists in the foundation laying out work, increases the accuracy of the laying out location, ensures that the actual laying out location precisely matches the design location, guarantees that the support installation meets design requirements, and solves the problem of secondary processing of the support caused by inaccurate foundation laying out during on-site support installation.

[0005] To achieve the above-mentioned technical objectives, this utility model provides an auxiliary device for setting up the foundation of a mountain photovoltaic pile. The auxiliary device includes a horizontal support rod and multiple vertical support rods. Each vertical support rod is arranged perpendicularly to the horizontal support rod and connected by adjusting bolts. The spacing between two adjacent vertical support rods matches the design spacing of the mountain photovoltaic pile foundation. A hammer component is provided at the connection point between each vertical support rod and the horizontal support rod. The hammer component is also connected to the horizontal support rod by adjusting bolts. When the adjusting bolts are loosened, both the hammer component and the vertical support rod are perpendicular to the horizontal support rod.

[0006] The preferred technical solution of this utility model is as follows: both the horizontal support rod and the vertical support rod are made of straight flat steel, and 3 to 5 vertical support rods are arranged, with the lower end of each vertical support rod having a tapered tip.

[0007] The preferred technical solution of this utility model is as follows: the lower hammer component adopts a circular steel plate with a counterweight, and when the adjusting bolt is loosened, the lower hammer component is naturally perpendicular to the horizontal support rod.

[0008] The preferred technical solution of this utility model is as follows: when the auxiliary device assists in setting up the foundation of the photovoltaic pile in the mountain, the horizontal support rod is parallel to the mountain slope, and the verticality of the vertical support rod is measured with a spirit level, and the verticality deviation does not exceed 1%.

[0009] The preferred technical solution of this utility model is that the center lines of the vertical support rod and the lower hammer component are at the same position.

[0010] The horizontal support rod of this utility model has a certain rigidity and is mainly used to form a straight line along the pile position, and its length can be adjusted according to the actual site conditions. The adjustable bolt is used to connect and fasten the horizontal support rod, the hammer component and the vertical support rod. The hammer component is mainly used to check the vertical state of the vertical support rod by its own weight when the adjustable bolt is loosened. The vertical support rod is mainly used to determine the actual site position after it is vertical, and its number can be adjusted according to the actual site conditions.

[0011] The beneficial effects of this utility model are:

[0012] The device of this utility model has a simple structure and is easy to use. It can be used in conjunction with existing pile foundation setting techniques to assist in pile foundation setting work, increase the accuracy of the setting position, and ensure that the actual setting position can be precisely matched with the design position. This ensures that the support installation meets the design requirements and solves the problem of secondary processing of the support caused by inaccurate foundation setting during on-site support installation.

[0019] To make the technical problems, solutions, and advantages of this utility model more apparent, the present utility model will be further described in detail below with reference to the accompanying drawings. The technical solutions presented below are specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] The embodiment provides an auxiliary device for setting up photovoltaic pile foundations in mountainous areas, such as... Figure 1 and Figure 2 As shown, the auxiliary device includes a horizontal support rod 1 and multiple vertical support rods 4, each with a tapered tip at its lower end. Each vertical support rod 4 is perpendicularly arranged to the horizontal support rod 1 and connected by adjusting bolts 2. The spacing between adjacent vertical support rods 4 matches the design spacing of the mountain photovoltaic pile foundation. A hammer component 3 is provided at the connection point between each vertical support rod 4 and the horizontal support rod 1. The hammer component 3 is also connected to the horizontal support rod 1 by adjusting bolts 2. When the adjusting bolts 2 are loosened, both the hammer component 3 and the vertical support rod 4 are perpendicular to the horizontal support rod 1. This allows the hammer component 3 and the vertical support rod 4 to naturally remain vertical under their own weight, even under different slope conditions. Both the horizontal support rod 1 and the vertical support rod 4 are made of straight flat steel. The horizontal support rod 1 has a certain rigidity and is mainly used to form a straight line along the pile position without deviation. Its length can be adjusted according to the actual site conditions. The hammer component 3 is a circular steel plate with a counterweight. When the adjusting bolt 2 is loose, the hammer component 3 is naturally perpendicular to the horizontal support rod 1. The hammer component 3 is used to check whether the vertical support rod 4 is in a vertical state.

[0021] In this embodiment, three vertical support rods 4 are arranged. The centerline of each vertical support rod 4 should be completely aligned with the centerline of the lower hammer component 3, and the adjustable bolts 2 should be locked to achieve the requirement of fixing the vertical flat steel. The auxiliary device is used to assist in the placement of the mountain photovoltaic pile foundation, such as... Figure 4 As shown, the horizontal support rod 1 is parallel to the mountain slope 5, and the verticality of the vertical support rod 4 is measured using a spirit level. The verticality deviation must not exceed 1% to avoid errors in the pile foundation spacing caused by verticality deviation. The spacing between two adjacent adjustable bolts 2 is marked using a calibrated measuring tape, and is re-measured daily to ensure compliance with design requirements.

[0022] The auxiliary device in this embodiment is used as follows: First, based on the pile foundation locations on the design drawings, two control points are located at the coordinates of a certain set of support foundations on site. Then, based on the terrain slope, the adjustable bolts 2 are loosened to make the vertical support rod 4 naturally vertical. The verticality of the vertical support rod 4 is verified by observing the hammer component 3. Then, the bottom of the vertical support rod 4 is aligned with one of the control points, and the horizontal support rod 1 is kept parallel to the line connecting the two control points. Figure 4 As shown, the three vertical support rods at the designated points are the actual placement points on site. Wooden sticks or bamboo are then manually inserted into these points to ensure consistent pile spacing. When manually placing these points, the tools used should be wooden sticks or bamboo with red paint on the top for easy identification by the pile drivers.

[0023] The following is a comparison of the use of this utility model's auxiliary point placement method with existing point placement techniques, using a specific construction case. This case involves point placement on a 25° slope mountain. The spacing between two adjacent pile foundation points in the design drawings is 370 mm. If conventional point placement methods are used, directly based on the plan layout of the design drawings, as shown in the attached diagram... Figure 3 As shown, the actual pile foundation spacing is greater than the 370mm required in the design drawings, which necessitates secondary processing such as drilling holes in the supports during on-site construction, significantly increasing the installation difficulty. However, by using the auxiliary tools described in this invention for pile placement, such as... Figure 4 As shown, the first step is to locate two control points on site based on the coordinates of a certain set of support foundations according to the design drawings; the second step is to loosen the adjustable bolts 2 of the device to make the vertical support rod 4 naturally vertical according to the terrain slope; the third step is to verify whether the vertical support rod 4 is naturally vertical by using a round steel plate with a weight for observation; the fourth step is to align the bottom of the vertical support rod 4 with one of the control points and ensure that the horizontal support rod 1 is parallel to the line connecting the two control points, and the landing points of the three vertical flat steel bars are the actual placement points on site; the fifth step is to manually insert wooden sticks or bamboo into the actual placement points to ensure that the pile foundation spacing is consistent; after using the auxiliary device for placement, the spacing of the actual points is basically consistent with the spacing of the design points.

[0024] The above description is merely one embodiment of this utility model, and while it is quite specific and detailed, it should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
