Abstract

This application provides a column structure and a heliostat. The column structure includes a tubular column comprising a first segment and a second segment arranged axially. The first segment and the second segment are fixedly connected. The first segment is located within a mounting hole in the ground, and a gap exists between the outer wall of the first segment and the inner wall of the mounting hole. The second segment is located outside the mounting hole. The tubular column defines a grouting space that extends axially through the first segment and the second segment.

The column structure of this application, by configuring the tubular column as a first segment within the mounting hole and a second segment above the ground, eliminates the need to wait for the concrete to solidify before connecting it to a steel column, thus improving construction efficiency and shortening the construction period.

Description

Technical Field

[0001] This application relates to the field of heliostat installation equipment technology, and in particular to a column structure and a heliostat. Background Technology

[0002] With the rapid development of renewable energy technologies, concentrated solar power (CSP) plants, as an important form of solar energy utilization, have gradually received widespread attention. Heliostats are key components in CSP plants; their main function is to reflect sunlight onto the heat-absorbing tower to achieve heat collection and power generation.

[0003] To ensure the stability and precise positioning of heliostats, reliable support and foundation structures are typically designed. Currently, a combination of reinforced concrete piles and steel columns is commonly used in the construction of heliostat supports and foundations.

[0004] Traditionally, there are two main methods for constructing reinforced concrete piles: hammer driving and borehole installation. Hammer driving involves using a pile driver to drive precast reinforced concrete piles into the soil. This method requires frequent movement of the pile driver and parameter adjustments for each pile location, leading to low construction efficiency, especially in large-scale solar thermal power plant projects, such as 100MW plants requiring over 10,000 piles. Furthermore, the noise and vibration generated during hammering have adverse effects on the surrounding environment, particularly in dense sandy soil foundations where pile driving can be difficult. The other method is borehole installation, which involves pre-drilling holes in the ground, inserting reinforced concrete piles, and then pouring concrete around the piles. This method reduces the environmental impact of hammering and is suitable for dense soil layers. However, because a connector is needed between the pile top and the upper steel column, the pile diameter must be larger than the diameter of the upper steel column, increasing the drilling diameter and construction difficulty. Additionally, the installation of the upper steel column can only proceed after the pile foundation has been accepted, still constraining the project schedule.

[0005] Therefore, existing technologies suffer from low construction efficiency, significant environmental impact, and long construction periods in the construction of heliostat supports and foundations. Utility Model Content

[0006] This application provides a column structure and a heliostat, which sets the column as a first section inside the mounting hole and a second section above the ground. This eliminates the need to wait for the concrete to solidify before connecting it to the steel column, thereby improving construction efficiency and shortening the construction period.

[0007] On the one hand, this application provides a column structure for installing heliostats, the column structure comprising:

[0008] The tubing column includes a first section and a second section arranged axially, the first section and the second section being fixedly connected. The first section is located inside a mounting hole in the ground, and there is a gap between the outer wall of the first section and the inner wall of the mounting hole. The second section is located outside the mounting hole.

[0009] The tubular column defines a grouting space that extends axially through the first and second sections. The grouting space is connected to the outside and to the mounting hole, allowing concrete poured into the grouting space to flow into the gap.

[0010] This utility model's column structure consists of a first section inside the installation hole and a second section above the ground. Concrete grout is injected into the grouting space within the column to fill the grouting space and the gap between the outer wall of the first section and the inner wall of the installation hole. This eliminates the need to wait for the concrete to solidify before installing the upper steel column, effectively shortening the construction period. Furthermore, it eliminates the need for piling machines requiring multiple adjustments, significantly reducing construction difficulty.

[0011] In some embodiments, the bottom of the first segment is provided with a grouting notch, and the grouting space communicates with the mounting hole through the grouting notch.

[0012] According to some embodiments of the present invention, there are multiple grouting notches, and the multiple grouting notches are arranged at intervals along the circumference of the pipe column.

[0013] In some embodiments, a grouting hole is provided on the peripheral wall of the second segment, and the grouting space is connected to the outside through the grouting hole.

[0014] In some embodiments, the column structure further includes:

[0015] The first reinforcing member is disposed on the peripheral wall of the first segment, and the first reinforcing member is used to improve the connection stability between the first segment and the concrete.

[0016] According to some embodiments of the present invention, there are multiple first reinforcing members, and the multiple first reinforcing members are spaced apart along the axial direction of the tubular column.

[0017] According to some embodiments of the present invention, the first reinforcing member includes a steel hoop, which surrounds the peripheral wall of the first segment.

[0018] According to some embodiments of the present invention, the first reinforcing member includes a plurality of reinforcing posts, which are spaced apart on the periphery of the first segment and extend toward the inner wall of the mounting hole.

[0019] According to some embodiments of this utility model, the column structure further includes:

[0020] The second reinforcing member is located on the second section, and the second section is supported on the ground by the second reinforcing member.

[0021] On the other hand, this application provides a heliostat, comprising: a mirror body, the aforementioned column structure, wherein the column structure is disposed on the ground, and the mirror body is disposed on the column structure.

[0022] The heliostat of this invention, due to the use of the aforementioned column structure, only requires the column structure to be installed into the mounting hole opened in the ground during installation. Then, concrete grout is injected into the grouting space inside the column using grouting equipment. The concrete grout fills the gap between the grouting space and the mounting hole, and after solidification, it provides good fixation for the column, shortens the construction cycle, and helps improve construction efficiency.

Detailed Implementation

[0035] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0036] Current technologies for heliostat support and foundation construction commonly employ a combination of reinforced concrete piles and steel columns. The construction of reinforced concrete piles primarily involves two methods: hammer driving and borehole installation. Hammer driving requires frequent movement of the pile driver and parameter adjustments at each pile location, resulting in low construction efficiency. Furthermore, the noise and vibration generated during hammering have adverse effects on the surrounding environment. Borehole installation involves pre-drilling holes in the ground, then inserting the reinforced concrete piles and pouring concrete around them. However, the installation of the upper steel columns can only proceed after the pile foundation project has been accepted, which still constrains the project schedule.

[0037] In view of this, this application provides a column structure and a heliostat, which sets the column as a first section inside the mounting hole and a second section above the ground, eliminating the need to wait for the concrete to solidify before connecting it to the steel column, thus improving construction efficiency and shortening the construction period.

[0038] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0039] refer to Figure 1 and Figure 2 In one aspect, this utility model discloses a column structure 100 for installing a heliostat. The column structure 100 may include a tubular column 110. The tubular column 110 includes a first segment 111 and a second segment 112 arranged along the axial direction. The first segment 111 and the second segment 112 are fixedly connected. Exemplarily, the first segment 111 and the second segment 112 may be integrally formed, or the first segment 111 and the second segment 112 may also be fixedly connected by means of flange connection or welding.

[0040] The first segment 111 is located inside the mounting hole 200 set in the ground. There is a gap between the outer wall of the first segment 111 and the inner wall of the mounting hole 200. By pouring concrete into the gap, the first segment 111 is fixed inside the mounting hole 200, providing good support for the column structure 100. The second segment 112 is located outside the mounting hole 200, providing support and mounting foundation for the heliostat body.

[0041] Understandably, when the first section 111 and the second section 112 of the pipe column 110 of this application are integrally formed, the pipe column 110 can be directly installed into the mounting hole 200. When the first section 111 and the second section 112 are fixedly connected by flange connection or welding to form an integral structure, the first section 111 and the second section 112 of the pipe column 110 can be pre-processed and fixed during the construction and installation of the column structure 100. In this way, it is ensured that the pipe column 110 can be an integral structure during installation.

[0042] The tubing string 110 defines a grouting space 113 that extends axially through the first segment 111 and the second segment 112. The grouting space 113 communicates with the outside. For example, the grouting space 113 can extend directly from the bottom end of the first segment 111 to the top end of the second segment 112, so that the tubing string 110 is formed as a sleeve, thereby communicating with the outside. Alternatively, a channel (such as the grouting hole 1121 described below) can be provided on the peripheral wall of the second segment 112, through which the grouting space 113 communicates with the outside.

[0043] The grouting space 113 is connected to the mounting hole 200. For example, when the column 110 is formed as a sleeve structure, the lower end of the first section 111 can be connected to the mounting hole 200. Alternatively, a flow hole or flow gap can be provided on the peripheral wall of the first section 111. The grouting space 113 is connected to the mounting hole 200 through the flow hole or flow gap. In this way, during the installation of the column structure 100, the column 110 is installed in the mounting hole 200. Concrete grout is introduced into the grouting space 113 through an external grouting device. The concrete grout flows from the grouting space 113 to the gap between the outer wall of the first section 111 and the inner wall of the mounting hole 200, so that the column structure 100 is fixedly installed in the mounting hole 200. In this way, only the installation and grouting process of the column 110 needs to be performed, and then the mirror body of the heliostat can be installed. This reduces the installation process and helps to speed up the construction progress.

[0044] The column structure 100 of this invention comprises a first section 111 within the mounting hole 200 and a second section 112 above ground level. Concrete grout is injected into the grouting space 113 within the column 110 to fill the gap between the grouting space 113 and the outer wall of the first section 111 and the inner wall of the mounting hole 200. This eliminates the need to wait for the concrete to harden before installing the upper steel column, effectively shortening the construction period. Furthermore, it eliminates the need for piling machines requiring multiple adjustments, significantly reducing construction difficulty.

[0045] In some embodiments, a grouting notch 1111 is provided at the bottom of the first segment 111, and the grouting space 113 communicates with the mounting hole 200 through the grouting notch 1111. Thus, by providing the grouting notch 1111 at the bottom of the first segment 111, the grouting material can flow more directly and evenly into the gap of the mounting hole 200. Simultaneously, the presence of the grouting notch 1111 allows the grouting material to fill the gap from the bottom of the mounting hole 200 and gradually flow upwards, ensuring the stability of the bottom of the entire column structure 100. This bottom-up filling method helps eliminate air bubbles and voids in the concrete grout, improving grouting quality. Furthermore, the design of the grouting notch 1111 simplifies the construction process, reduces the requirements for grouting equipment, and helps reduce construction difficulty and shorten construction time.

[0046] Optionally, the grouting notch 1111 can be set on the peripheral wall near the bottom of the first section 111, or the grouting notch 1111 can extend downward to the bottom wall of the first section 111. In this way, during the grouting process, the concrete grout flows from the grouting notch 1111 into the gap. At this time, the part of the bottom wall of the first section 111 other than the grouting notch 1111 forms a support seat, which improves the stability of the pipe column 110 during the grouting process.

[0047] According to some embodiments of this utility model, there are multiple grouting notches 1111, which are arranged at intervals along the circumference of the pipe column 110. For example, there may be two grouting notches 1111, arranged at 180° intervals along the circumference of the pipe column 110; or there may be three grouting notches 1111, arranged at 120° intervals along the circumference of the pipe column 110; or there may be four grouting notches 1111, arranged at 90° intervals along the circumference of the pipe column 110.

[0048] Multiple grouting notches 1111 are arranged circumferentially to ensure that concrete grout can enter the gap of the installation hole 200 simultaneously from multiple directions. This facilitates uniform distribution of the concrete grout, reduces the formation of local voids, and improves the overall structural stability. Simultaneously, the design of multiple grouting notches 1111 accelerates the grouting process, allowing the concrete to fill the gap more quickly and shortening construction time.

[0049] In this embodiment, it should be noted that the number of grouting gaps 1111 should not be too many. Too many grouting gaps 1111 will reduce the strength of the lower end of the pipe column 110, reduce the supporting effect of the first section 111, and even cause the pipe column 110 to tilt during the concrete grouting process.

[0050] In some embodiments, a grouting hole 1121 is provided on the peripheral wall of the second section 112, and the grouting space 113 is connected to the outside through the grouting hole 1121. By providing the grouting hole 1121 on the peripheral wall of the second section 112, construction personnel can directly inject concrete grout into the grouting space 113 from above the ground, which helps to simplify the construction steps, reduce the requirements for construction equipment, and speed up the construction cycle.

[0051] Understandably, the grouting space 113 can also be connected to the outside through the top of the second section 112. When pouring concrete grout into the grouting space 113 using grouting equipment, the grouting can also be done at the top of the second section 112, where the opening is larger and the grouting efficiency is higher. Of course, by grouting through grouting holes 1121 on the perimeter wall of the second section 112, construction personnel can adjust the height of the grouting holes 1121 according to the actual conditions of the construction site, making the grouting operation more convenient.

[0052] In some embodiments, the column structure 100 may further include a first reinforcing member 120, which is disposed on the peripheral wall of the first segment 111. The first reinforcing member 120 is used to improve the connection stability between the first segment 111 and the concrete. Exemplarily, the first reinforcing member 120 may be a portion of the first segment 111 protruding into the inner wall of the mounting hole 200, such as a ring platform. The first reinforcing member 120 increases the contact area between the first segment 111 and the concrete, thereby improving the installation stability of the first segment 111. Alternatively, the first reinforcing member 120 may also be a support structure on the outer wall of the first segment 111. The first segment 111 can be supported within the mounting hole 200 by the support structure. Simultaneously, the support structure also increases the contact area between the first segment 111 and the concrete to a certain extent, thereby improving the installation stability of the first segment 111.

[0053] In addition, the setting of the first reinforcing member 120 is also conducive to optimizing the force transmission path on the column structure 100, providing multiple force application points for the first segment 111, so as to avoid the single-point force damage of the column 110, thereby improving the reliability of the column structure 100 and extending the service life of the column structure 100.

[0054] According to some embodiments of this utility model, there are multiple first reinforcing members 120, which are spaced apart along the axial direction of the column 110. This arrangement of multiple first reinforcing members 120 along the axial direction of the first segment 111 increases the contact area and friction between the first segment 111 and the surrounding concrete. This design effectively improves the column's pull-out resistance and overturning resistance, ensuring the stability of the structure under different load conditions. The axially spaced arrangement of multiple first reinforcing members 120 helps to evenly distribute external forces, reduce local stress concentration, and lower the risk of damage to the column structure 100. Through multi-point reinforcement, the strength and durability of the entire column structure 100 are significantly improved, adapting to higher load requirements. By axially spaced multiple first reinforcing members 120 on the peripheral wall of the first segment 111, the connection stability and overall strength of the column structure 100 are further improved, providing a more reliable and stable foundation for the installation of the heliostat.

[0055] Understandably, the design of multiple first reinforcement members 120 can be adjusted according to specific construction environments and requirements to adapt to different geological conditions and engineering needs.

[0056] According to some embodiments of this utility model, the first reinforcing member 120 may include a steel hoop that surrounds the peripheral wall of the first segment 111. On the one hand, the surrounding design of the steel hoop provides additional mechanical fixing force, increases the friction and contact area between the first segment 111 and the concrete, thereby improving the pull-out resistance and overturning resistance of the column. On the other hand, the use of the steel hoop also helps to disperse external forces, reduce local stress concentration, and enhance the structural strength and durability of the entire column structure 100.

[0057] According to some embodiments of this utility model, the first reinforcing member 120 may include a plurality of reinforcing columns, which are spaced apart around the periphery of the first segment 111 and extend toward the inner wall of the mounting hole 200. The design of the reinforcing columns extending toward the inner wall of the mounting hole 200 increases the mechanical interlocking force between the first segment 111 and the surrounding concrete. This design effectively improves the pull-out resistance and overturning resistance of the column structure 100. The presence of multiple reinforcing columns helps to disperse external forces, reduce local stress concentration, and enhance the overall structural strength and durability of the column.

[0058] Understandably, the reinforcing column can extend to the inner wall of the mounting hole 200, thereby improving the supporting effect of the mounting hole 200 on the first section 111, and thus improving the pull-out resistance and overturning resistance of the column structure 100.

[0059] According to some embodiments of this utility model, the column structure 100 may further include a second reinforcing member, which is disposed on the second segment 112, and the second segment 112 is supported on the ground by the second reinforcing member. Exemplarily, the second reinforcing member may include a mounting ring and multiple support arms. The mounting ring is fixedly installed on the outer wall of the second segment 112 by welding or bolted connections. The multiple support arms are spaced apart around the axis of the second segment 112, with one end of each support arm supporting the ground and the other end connected to the mounting ring. The mounting ring has a mounting notch, and the end of the support arm away from the ground is installed in the mounting notch by a pin. The support arms can be tilted to support the ground, providing additional support force to the column 110, enabling the second segment 112 to stand more stably on the ground and improving the overall structural stability.

[0060] The second reinforcing member enhances the support area and contact force of the second section 112, thereby improving the overturning resistance of the column structure 100, especially when facing lateral forces. The second reinforcing member also helps to evenly distribute the load from the heliostat to the ground, reducing localized stress concentration and extending the structure's service life.

[0061] Understandably, during the grouting process into the grouting space 113, the concrete grout gradually fills the gap between the outer wall of the first section 111 and the mounting hole 200. Multiple enclosing plates connected end to end can be arranged around the mounting hole 200 on the ground. The enclosing plates enclose a reinforced space, and all the enclosing plates are inclined towards the column structure 100, forming an opening at the top.

[0062] After the concrete grout gradually fills the gap between the outer wall of the first section 111 and the mounting hole 200, grouting continues, allowing the concrete grout to continue filling the reinforced space. After the concrete grout solidifies, a reinforcing boss is formed at the intersection of the first section 111 and the second section 112. The reinforcing boss can constitute a third reinforcing member, further improving the anti-overturning ability of the column structure 100, thereby making the column structure 100 more resistant to lateral forces and extending the service life of the heliostat.

[0063] On the other hand, this application provides a heliostat, which may include: a mirror body and the aforementioned column structure 100, wherein the column structure 100 is disposed in a mounting hole 200 on the ground, and the mirror body is disposed in the column structure 100.

[0064] The heliostat of this invention, using the aforementioned column structure 100, only requires installing the column structure 100 into the mounting hole 200 opened in the ground during installation. Then, concrete grout is injected into the grouting space 113 inside the column 110 using grouting equipment. The concrete grout fills the gap between the grouting space 113 and the mounting hole 200. After solidification, it provides good fixation for the column 110, has a short construction cycle, and helps improve construction efficiency.
