[0035] Reference Figures 1 to 11 , a kind of heliostat pile hole auxiliary construction device (hereinafter referred to as auxiliary construction device) of the utility model, including vertical support rod 2, the upper and lower ends of vertical support rod 2 are respectively provided with handheld part 1 and bottom pressure plate 3, scale mark 21 is arranged on the rod of vertical support rod 2, the outer diameter of bottom pressure plate 3 is less than the inner diameter of pipe pile hole.As shown in Figure 4 , 5 As shown, bottom pressure plate 3 includes soil scraping part 31 and tamping part 32 from top to bottom, soil scraping part 31 is the circular table structure of small up and big down, the circumferential surface of circular table structure is concave arc surface 33, so that soil scraping part 31 is thin from inside to outside, on the one hand, it is convenient to scrape soil, on the other hand, it can guarantee the structural strength of entire bottom pressure plate 3, facilitate cooperation with tamping part 32, carry out tamping operation.The thickness of tamping part 32 is not greater than the thickness of soil scraping part 31, so that the spacing between the bottom surface of bottom pressure plate 3 and soil scraping part 31 can be reduced, and the bottom sediment can be scraped out conveniently.Horizontal monitoring unit is arranged on handheld part 1, vertical support rod 2 is composed of multiple support rod units 22, as shown in Figure 2 , the opposite ends of two adjacent support rod units 22 are threadedly connected.

[0036] Specifically, in the embodiment, as shown in Figure 1 , 3 As shown, support rod unit 22 can be divided into top support rod 221, middle support rod 222 and bottom support rod 223 from top to bottom, wherein the upper end of top support rod 221 is threadedly connected with the lower end center of handheld part 1, and the lower end of bottom support rod 223 is threadedly connected with the center of bottom pressure plate 3.On the one hand, it is convenient for assembly, on the other hand, it is convenient for distinguishing, and the assembly efficiency is improved.

[0037] Preferably, in the present embodiment, the auxiliary construction device further comprises a binding ring assembly 5 detachably mounted on the vertical support rod 2, which is used to fold up the support rod units 22 when not in use. Specifically, as shown in Figure 6 、 7 , the binding ring assembly 5 comprises a middle binding ring 51 and an outer peripheral binding ring 52 fixed on the periphery of the middle binding ring 51, and the inner diameter of the outer peripheral binding ring 52 and the inner diameter of the middle binding ring 51 are both adapted to the outer diameter of the vertical support rod 2.

[0038] In the present embodiment, the outer peripheral binding rings 52 are arranged in an array along the axis of the middle binding ring 51, and the total number of the middle binding ring 51 and the outer peripheral binding ring 52 is adapted to the number of the support rod units 22, wherein the middle binding ring 51 is sleeved on the bottom support rod 223, and the top support rod 221 and the middle support rod 222 are sleeved on the outer peripheral binding ring 52. In this way, when not in use, it is convenient to fold up the support rod units 22, and it is convenient to carry and recycle, saving space.

[0039] Preferably, in the present embodiment, the top of the support rod unit 22 is provided with a threaded rod 6, and the bottom of the support rod unit 22 is provided with an adapted threaded hole 7. The lower end of the hand-held part 1 is provided with a mounting part 11 threadedly connected with the threaded rod 6 of the top support rod 221, and the bottom of the mounting part 11 is also provided with a threaded hole 7 adapted to the threaded rod 6, and the axial length of the mounting part 11 is not less than the axial length of the threaded rod 6. As shown in Figure 4 、 5 , the center position of the upper end surface of the bottom pressing plate 3 is provided with a threaded rod 6 adapted to the threaded hole 7 of the bottom support rod 223.

[0040] In this way, as shown in Figure 8 、 9 , 10, when folded up, the middle support rod 222 and the top support rod 221 can be supported together with the bottom support rod 223 on the upper end surface of the bottom pressing plate 3, and the hand-held part 1 can be reliably mounted on the bottom support rod 223 through the mounting part 11, and will not interfere with the remaining support rod units 22. The integration is improved.

[0041] Preferably, in the present embodiment, the thickness of the tamping part 32 is not less than two-fifths of the thickness of the bottom pressing plate 3. In this way, the tamping part 32 can have sufficient strength and weight to effectively tamp the floating soil layer and improve the construction quality.

[0042] As shown in Figure 11As shown, in this embodiment, the level monitoring unit is a level ruler 4 containing a level bubble for observing the level. A mounting slot 8 adapted for the level ruler 4 is provided in the center of the upper end surface of the handle 1, and the level ruler 4 is mounted within the mounting slot 8. This facilitates observation of the leveling condition and protects the level ruler 4 from damage, thereby increasing its service life and measurement accuracy. Of course, in other embodiments, the level monitoring unit can also be an electronic level.

[0043] Preferably, in this embodiment, the handle 1 is a tow bar, the length of which matches the diameter of the bottom pressure plate 3, so that it is easy to lift and apply force to the vertical support rods 2. At the same time, when folding, the tow bar can be used to block the support rod units 22 to a certain extent, thereby preventing the support rod units 22 from moving. Of course, in other embodiments, the handle 1 can also be in the form of a disc, and the diameter of the disc can be matched to the diameter of the bottom pressure plate 3. In this way, when folding, the disc-shaped handle 1 can also block each support rod unit 22.

[0044] In this embodiment, the design diameter of the bottom pressure plate 3 needs to be 15cm to 20cm smaller than the inner diameter of the pipe pile hole to facilitate the extraction of bottom sediment. Specifically, in this embodiment, the bottom pressure plate 3 is cut into a circle using a 10mm thick steel plate, and the diameter of the bottom pressure plate 3 is designed to be 35cm. The outer periphery of the bottom pressure plate 3 is grinded with an angle grinder to reduce the thickness, and the grinding should start from 7cm close to the periphery, and the thickness decreases from the inside to the outside to form an inwardly concave arc surface 33. The thickness of the outermost part is maintained at about 4mm to form a tamped part 32 to avoid curling. Of course, in other embodiments, the above parameters can be adjusted according to actual needs, such as using an angle grinder to grind from 3mm close to the periphery of the bottom pressure plate 3 to form an arc surface, etc., which is not limited here.

[0045] In this embodiment, the vertical support rod 2 is a solid rod structure. Of course, in other embodiments, according to practical needs, the vertical support rod 2 can also be a hollow steel pipe.

[0046] The working process of this application is as follows: first, the auxiliary construction device is placed at the bottom of the hole, the scraping part 31 is used to collect the bottom sediment to one side, and the bottom debris and gravel are scraped and collected and extracted out of the hole.

[0047] After the slag layer is cleaned to the design requirements, hold the drag rod and use the tamping part 32 of the bottom pressure plate 3 to tamp repeatedly.

[0048] Use the scale mark 21 to observe the hole depth, and use the level ruler 4 to observe whether the bottom of the hole is horizontal. When the hole depth and the horizontal state of the hole bottom meet the design requirements, the operation is completed and the next step of pouring can be carried out.

[0049] Remove the middle support rod 222, the top support rod 221 and the hand-held part 1, put the middle restraint ring 51 of the restraint ring assembly 5 on the bottom support rod 223, put the middle support rod 222 and the top support rod 221 on the peripheral restraint ring 52, screw the mounting part 11 of the hand-held part 1 on the threaded rod 6 of the bottom support rod 223 to complete the storage.

[0050] In summary, the auxiliary construction device of the present invention uses a vertical support rod 2 to replace the traditional steel ruler for hole depth measurement. Due to its relatively stable structure and the scale mark 21 on the rod body, it can measure the hole depth more accurately, avoiding the inaccurate measurement caused by the steel ruler being unable to reach the bottom of the hole vertically due to its own lightness or bending at the bottom of the hole. The scraping part 31 and the tamping part 32 of the bottom pressure plate 3 can be used to clean sediment and tamp the floating soil layer respectively, and the bottom pressure plate 3 can be used to smash and extract the uneven parts of the hole wall, realizing multi-functional integration, reducing the number of tools and operating procedures, and making the overall operation process simpler.

[0051] The frustum and arcuate surface 33 of the scraping part 31 facilitate the collection of sediment. The level 4 on the handheld part 1 helps ensure that the device remains horizontal during measurement and construction, further improving the accuracy of measurement and construction, while ensuring the flatness of the hole bottom after tamping and the accuracy of subsequent heliostat installation. The vertical support rod 2 is composed of multiple support rod units 22 threaded together and can be flexibly assembled according to different pile hole depths, improving the applicability of the device and facilitating portability and recovery.

[0052] The device combines three operating tools, namely, hole depth measurement, hole bottom sediment cleaning, and surface soil compaction, into one. It has a simple structure and is easy to operate. It is suitable for various geological conditions and construction environments. It has strong on-site adaptability, a simple structure, low production cost, and easy operation. It greatly improves construction efficiency and quality, thereby facilitating the large-scale and rapid construction needs of heliostat fields. It is easy to construct and has strong promotion and application value.

[0053] Example 2: This example provides a different vertical support rod. Different from Example 1, in this example, each support rod unit of the vertical support rod is provided with a threaded hole at the upper end and a threaded rod adapted to the threaded hole at the lower end.

[0054] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and variations of the present application are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.

In addition, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0056] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly inclined.
