Description

Technical Field

[0001] The present invention relates to the technical field of concrete pile casting, and in particular to a mountain photovoltaic cast-in-place pile casting device and a casting process. Background Art

[0002] The photovoltaic support foundation is the key to ensuring the safe and normal operation of photovoltaic modules, and is the main construction content of the civil construction of photovoltaic power stations. The photovoltaic support foundation form adapted to local conditions is of great help in improving the ability of photovoltaic support power station systems to resist wind and snow loads.

[0003] Existing cast-in-place piles are divided into the following types: bored cast-in-place pile foundations, steel screw pile foundations, independent foundations, precast pile foundations, etc. In order to ensure the casting effect in mountainous areas, bored cast-in-place piles are usually used. The cost of bored cast-in-place piles is relatively low, and the hole is easy to form. At the same time, the elevation of the top surface of the foundation can be adjusted accordingly according to the terrain environment. Less materials are used, the construction is simple and quick, and the damage to the original terrain and surrounding vegetation is less. It is suitable for geological conditions such as clay, sand, and rock.

[0004] Therefore, when pouring bored cast-in-place piles, it is necessary to pre-embed the steel bars to achieve fixation between the concrete and the steel bars. However, after the existing bored cast-in-place piles are poured, the concrete needs to be disassembled and the solidified concrete needs to be cured. However, the shells of existing cast-in-place piles are mostly one-piece structures. After the concrete solidifies, due to the strong adhesion of the concrete, it is very difficult to disassemble the entire cast-in-place pile, and it is also easy to damage the surface of the solidified concrete. In addition, the existing one-piece cast-in-place piles cannot adjust the internal insulation layer according to the actual temperature conditions, the concrete solidification and curing effect is poor, and the cast-in-place piles and external protective equipment are also prone to rust when exposed to extreme weather such as rain and snow for a long time. Summary of the Invention

[0005] In order to overcome the problem in the above-mentioned background technology that the bored piles with an integrated structure are difficult to disassemble after the concrete solidifies, the present invention provides a mountain photovoltaic bored pile casting device and casting process. By dividing the casting device into a multi-layer structure, and each layer is spliced ​​by multiple side panels, it is easier to dismantle the blocks after the concrete solidifies, which greatly reduces the damage to the concrete surface.

[0011] Further preferably, the movable block is provided with a slot with a "∏"-shaped longitudinal section, a support frame is installed in the slot, the support frame is provided with an insulation layer, and the bottom of the support frame is fixedly connected to the bottom surface of the mounting slot through a magnetic block; the upper side of the arc-shaped bar body can be snapped into the fixed seat above the outer side surface of the side panel; a number of limit seats are provided on the base layer, which is the same as the number of the arc bars, and when the movable block is pulled out, the movable end of the arc bar can be inserted into the limit seat.

[0012] Preferably, a support bar is fixed on the top surface of each side panel of the top seat layer along its length direction, and a card block protruding upward is provided on the support bar. A baffle is laid on the top seat layer, and a card groove is provided on the bottom surface of the baffle. The position and shape of the card groove are matched with the card block; an annular handle is fixed in the middle of the upper surface of the baffle, and a number of handle grooves are evenly arranged around the annular handle.

[0013] Preferably, the inner side surface of each side panel is an arc-shaped surface structure, wherein the inner side of each side panel of the top seat layer is connected with a protective pad, the top and bottom of the protective pad respectively exceed the upper surface and lower surface of the side panel of the top seat layer, and the inner side of each side panel of the connecting layer and the top seat layer is connected with a protective plate, the top of the protective plate of the connecting layer is lower than the upper surface of the side panel of the connecting layer, and adjacent protective pads, adjacent protective plates, and adjacent protective pads and protective plates are tightly connected; the inner walls of the protective pads and protective plates are coated with an anti-adhesion coating; the casting cavity in the connecting layer and the top seat layer is a cylindrical cavity, and the casting cavity in the base is a truncated cone cavity with an upper bottom area smaller than a lower bottom area.

[0014] Preferably, a plurality of connecting rods are evenly fixed along the circumferential direction at the bottom of the connecting layer, and an annular groove is provided at the top of the base layer.

[0016] Compared with the existing technology, the above technical solution has the following beneficial effects:

[0017] (1) Since the pouring device is divided into a multi-layer structure, and each layer is composed of multiple side panels, it is easier to dismantle the blocks after the concrete solidifies, which greatly reduces the damage to the concrete surface. The divided components are also easier to transport, solving the problem in the background technology that the cast-in-place piles with an integrated structure need to be dismantled as a whole, which is very difficult and easy to damage the concrete surface after solidification.

[0018] (2) By coordinating and adjusting the limiting structure and the regulating structure, the adjacent side panels of the top seat layer can be tightly connected, thereby fixing the top seat layer and maintaining the overall stability of the top seat layer.

[0019] (3) Since the bottom of the support frame in the movable block is fixedly connected to the bottom surface of the mounting groove in the side plate through the magnetic block, and a rotatable arc strip is fixed on the outside of the movable block, the movable block can be pulled out of the movable block as a whole by rotating the arc strip. The casting device after removing the movable block can not only reduce the weight of the casting device as a whole, but also allow the casting device to be ventilated in the circumferential direction, which is conducive to better forming and solidification of concrete. The movable block is inserted into the limit seat and used in conjunction with the heat insulation cloth to prevent the protective equipment and the casting device from being eroded by rain and snow and causing rust. It can also prevent the concrete from cracking when exposed to high temperature for a long time.

[0020] (4) By arranging movable blocks in each side plate of the connecting layer and placing a replaceable heat-insulating layer in the movable blocks, the heat-insulating layer can be replaced in time according to the temperature in the air, thereby improving the solidification and curing effect of the concrete. This solves the problem in the background technology that the existing one-piece structure bored piles cannot replace the heat-insulating layer according to the actual temperature conditions, the concrete solidification effect is poor, and the bored piles and external protective equipment are also prone to rust when exposed to extreme weather such as rain and snow for a long time.

[0021] On the basis of the above technical solution, a casting process of a mountain photovoltaic cast-in-place pile casting device is also provided, comprising the following steps:

[0022] S1: Positioning and installing the pouring device. According to the orientation, leveling points and coordinate control points of the on-site solar power station, the base layer of the pouring device is fixed on the ground using the rectangular coordinate method, polar coordinate method, angle intersection method or distance intersection method, and the pouring device is installed.

[0023] S2: Drilling with a drill rod, adjusting the drill rod angle so that the drill rod drills a hole vertically into the ground within the pouring device, cleaning the loose soil after the hole is formed, and pre-treating the drill hole with cement;

[0024] S3: Place the steel cage and pour concrete into it. Place the steel cage into the pouring cavity of the pouring device and pour the mixed concrete into the pouring cavity to solidify the concrete and fix the steel cage into an integrated concrete pile.

[0025] S4: Curing concrete piles. After pouring in this pouring device, the concrete solidifies 12 to 18 hours later. Remove this pouring device. After the concrete is finished, spray the curing agent first, then use a film to cover and maintain it, and then sprinkle water every day for maintenance.

[0026] The beneficial effects of this technical solution are:

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] Example 1: Figures 1 to 6 The illustrated apparatus for pouring photovoltaic piles for mountainous terrain includes a base layer 3, a connecting layer 2, and a top layer 1. These layers are stacked from bottom to top, with their inner walls collectively forming a pouring cavity 41. This cavity, defined as a hollow structure between the base, connecting, and top layers, allows for concrete to be poured into the cavity. Each of these layers is constructed from multiple side panels 42. Each layer utilizes three to six side panels 42 to form a fence structure. Each layer has the same number of side panels 42; in this embodiment, four side panels 42 are used per layer.

[0038] When in use, the base layer 3, the connection layer 2 and the top seat layer 1 of the pouring device are first stacked one by one from bottom to top, and then the steel cage is placed in the pouring cavity 41. The concrete transport pipe is placed on the top of the top seat layer 1 and concrete is poured into the pouring cavity 41 from the opening of the top seat layer 1. The concrete flows to the base layer 3 and flows into the drilled hole in the middle of the ground. After pouring is completed, the concrete transport pipe is removed. After the concrete is allowed to stand until it is basically solidified, the side panels 42 of each layer are removed one by one from top to bottom, and the concrete pile is completed. Since the pouring device is divided into a multi-layer structure, and each layer is spliced ​​with multiple side panels 42, it is easier to dismantle the blocks after the concrete solidifies, which greatly reduces damage to the concrete surface. The blocks are also easier to transport, solving the problem of the bored piles of the background art that the integral structure needs to be dismantled as a whole, which is very laborious and easy to damage the solidified concrete surface.

[0039] Example 2: Based on Example 1, the top seat layer 1 is preferably designed as follows: Figure 2 As shown, a limiting structure 10 is arranged on the top between the adjacent side plates 42 of the top seat layer 1, as shown in FIG. Figure 4 As shown, the limiting structure 10 includes a limiting head 11 and a limiting plate 12. The limiting head 11 is vertically fixed to the outer end surface of the top end of the side plate 42. The limiting plate 12 is horizontally arranged between adjacent side plates 42. The limiting plate 12 is provided with a plurality of limiting holes 121 along its length. The limiting holes 121 are inserted into the limiting heads 11 on both sides. The limiting heads 11 can be connected to different limiting holes 121 to adjust the spacing between adjacent side plates 42 and keep the adjacent side plates 42 of the top seat layer 1 closely connected. Figure 2 As shown, an adjustment structure 13 is also arranged on the top between the adjacent side plates 42 of the top seat layer 1, as shown in FIG. Figure 4 As shown, the adjustment structure 13 includes an adjustment seat 14 and a screw 15. The adjustment seat 14 is vertically fixed to the outer end surface of the top end of the side panel 42. A threaded hole is opened in the adjustment seat 14. The screw 15 is horizontally arranged between adjacent side panels 42, with both ends passing through the threaded holes. The screw 15 is rotated to adjust the spacing between adjacent side panels 42, keeping the adjacent side panels 42 of the top seat layer 1 tightly connected. Among them, the limiting structure 10 and the adjustment structure 13 are arranged at intervals at the top between adjacent side panels 42, that is, one end of each side panel 42 of the top seat layer 1 is connected to the limiting structure 10, and the other end is connected to the adjustment structure 13.

[0040] When installing the top seat layer 1, first place the side panels 42 of the top seat layer 1 one by one on the corresponding side panels 42 of the connecting layer 2, and then the two sides of each side panel 42 of the top seat layer 1 are tightly connected with the adjacent side panels 42 through the limiting structure 10 and the adjusting structure 13 respectively. When installing the limiting structure 10, the limiting holes 121 at the appropriate position in the limiting plate 12 are inserted into the two limiting heads 11 of the adjacent side panels 42 to keep the two side panels 42 tightly connected. When installing the adjusting structure 13, rotate the screw rod 15 and pass the screw rod 15 through the threaded holes of the two adjustment seats 14 of the adjacent side panels 42 until the two side panels 42 are tightly connected. During actual use, the limiting structure 10 and the adjusting structure 13 can be repeatedly adjusted until the adjacent side panels 42 of the top seat layer 1 can be tightly connected. If the limiting structure 10 or the adjusting structure 13 is used alone, since the number of limiting holes 121 of the limiting plate 12 is limited, the adjustment position is also limited, and it is impossible to ensure that each group of adjacent side panels 42 are tightly connected. If it is only connected through the screw rod 15 of the adjusting structure 13, since the screw rod 15 needs to maintain a straight line when rotating, if each side panel 42 is connected by the screw rod 15, gaps are likely to appear between the adjacent side panels 42. In more serious cases, concrete will accumulate at the screw rod 15, making it impossible to remove the screw rod 15. Therefore, only through the combined adjustment of the limiting structure 10 and the adjusting structure 13 can the adjacent side panels 42 of the top seat layer 1 be tightly connected, thereby achieving the fixation of the top seat layer 1 and maintaining the overall stability of the top seat layer 1. When the top seat layer 1 needs to be removed, the limit plate 12 is pulled out from the limit head 11, and then the screw rod 15 is rotated in the opposite direction to disengage the screw rod 15 from the threaded hole of the adjustment seat 14 on one side, and then the side plates 42 of the top seat layer 1 are removed one by one from the side plates 42 of the connecting layer 2. The block-by-block removal operation is easy and can also reduce damage to the solidified concrete.

[0041] Example 3: Based on Example 1, the connection layer 2 is preferably designed, such as Figures 5 and 6 As shown, a mounting groove 21 is provided in each side panel 42 of the connecting layer 2. The mounting groove 21 penetrates the side panel 42 from the inside to the outside. A movable block 22 is connected to the mounting groove 21. The bottom of the movable block 22 maintains a stable connection with the mounting groove 21. A connecting seat 23 is fixed to the lower part of the outer side surface of the movable block 22. The bottom of the arc-shaped bar 24 is stuck in the connecting seat 23. The connecting shaft 231 passes through the connecting seat 23 and the arc-shaped bar 24 to connect the two. The arc-shaped bar 24 can rotate around the connection point. The top of the arc-shaped bar 24 can be tilted toward the outside of the side panel 42. When the movable block 22 rotates clockwise toward the inside of the side panel 42, the movable block 22 can be pulled out of the mounting groove 21 through the connecting seat 23.

[0042] Further, such as Figure 5As shown, a slot 25 with a longitudinal section in the shape of "∏" is provided in the movable block 22, and a support frame 26 is placed in the slot 25. The support frame 26 slides upward into the slot 25 from the opening at the bottom of the slot 25, and the bottom of the support frame 26 is fixedly connected to the bottom surface of the mounting slot 21 in the side panel 42 through a magnetic block 261. The longitudinal section of the support frame 26 is in the shape of "]", and a placement slot 27 is provided therein, and a heat insulation layer 28 is installed in the placement slot 27.

[0043] Furthermore, a fixing seat 29 is fixed to the outer side surface of the upper part of the side panel 42 of the connecting layer 2 (above the mounting groove 21). When the arc strip 24 is fixed, the upper side of its body can be snapped into the fixing seat 29, further improving the connection stability between the movable block 22 and the side panel 42.

[0044] Further, if Figure 1 As shown, a number of limiting seats 37 are provided on the base layer 3 , the number of which is the same as the number of the arc strips 24 . When the movable block 22 is pulled out, the movable end of the arc strip 24 can be inserted into the limiting seat 37 .

[0045] During use, when the connecting layer 2 needs to be installed, first place the support frame 26 with the insulation layer 28 placed on it into the slot 25 from the opening at the bottom of the movable block 22, and then place the movable block 22 into the mounting slot 21 of the side panel 42. The magnetic block 261 at the bottom of the support frame 26 is fixedly connected to the bottom surface of the mounting slot 21 by magnetic attraction. Then, rotate the arc bar 24 upward, and snap the body of the arc bar 24 into the fixed seat 29 to maintain a stable connection between the movable block 22 and the side panel 42. Finally, place the installed side panels 42 one by one on the corresponding side panels 42 of the base layer 3, and tightly connect the adjacent side panels 42 together. Since the top seat layer 1 is also placed above the connecting layer 2, under the action of the gravity of the top seat layer 1, the side panels 42 tightly connected together by the connecting layer 2 are not easy to move. Therefore, there is no need to set a connecting mechanism between the side panels 42 of the connecting layer 2 to keep the adjacent side panels 42 tightly connected. When the connection layer 2 needs to be removed, after the top seat layer 1 is removed, the side panels 42 of the connection layer 2 are removed one by one, and then the movable block 22, the support frame 26 and the heat insulation layer 28 inside are taken out in sequence.

[0046] In addition, after the concrete pouring is completed, the heat insulation layer 28 in the support frame 26 needs to be adjusted according to the temperature in the air at that time, so as to realize the protection effect of the concrete and ensure the finished product quality of the concrete pile. Since the bottom of the support frame 26 is fixedly connected with the bottom surface of the mounting groove 21 in the side plate 42 through the magnetic block 261, the movable block 22 can be rotated clockwise to the inside of the side plate 42, so that the movable block 22 can be pulled out from the mounting groove 21 as a whole by using the arc-shaped strip 24 through the connecting seat 23, and then the support frame 26 can be slid out of the opening at the bottom of the slot 25, and then the heat insulation layer 28 can be taken out from the side of the support frame 26, so as to replace the heat insulation layer 28. Similarly, when the concrete needs to be ventilated, the movable block 22 can be pulled out from the mounting groove 21 as a whole by rotating the arc-shaped strip 24, so as to reduce the weight of the pouring device as a whole and enable the pouring device to be ventilated in the circumferential direction, which is beneficial to the better forming and solidification of the concrete. In addition, after the arc-shaped strip 24 is removed, the top end of the arc-shaped strip 24 can be inserted into the limiting seat 37 in reverse, and the heat insulation cloth can be covered on the top seat layer 1 in rainy and snowy weather or in sunny weather, and the heat insulation cloth below is inclined and supported by the top of the movable block 22. The external protection equipment can be placed under the heat insulation cloth, so as to prevent the protection equipment and the pouring device from being eroded by rain and snow and rusting, and also prevent the concrete from cracking in long-term high temperature and sun exposure.

[0047] Example 4: The top seat layer 1 is preferably designed on the basis of example 1, as shown in Figure 2 Each side plate 42 of the top seat layer 1 has a support strip 16 fixed on the top surface outside in the length direction, and the support strip 16 is provided with a clamping block 17 protruding upward, as shown in Figure 1 The top surface of the top seat layer 1 is connected with a horizontally arranged baffle 18, the bottom surface of the baffle 18 is provided with a clamping groove, the opening position and shape of the clamping groove are matched with the clamping block 17, the baffle 18 is placed on the top seat layer 1 when the pouring device needs to be shielded, the clamping block 17 is aligned and embedded in the clamping groove, the baffle 18 and the top seat layer 1 are stably connected, and the sealing and protection effect of the concrete is realized. The surface of the baffle 18 is fixed with a ring handle 181, and a plurality of handle grooves 182 are uniformly arranged on the circumference of the ring handle 181. The handle grooves 182 are arranged, so as to facilitate the removal of the baffle 18.

[0048] Example 5: The side plate 42 is preferably designed on the basis of example 1, as shown in Figure 3As shown, the inner side surface of each side panel 42 is an arc-shaped surface structure, wherein each side panel 42 of the top seat layer 1 is fixedly connected to the inner wall with a protective pad 43, and the top of the protective pad 43 extends upward beyond the upper surface of the side panel 42 of the top seat layer 1, wherein the top of the protective pad 43 protrudes outward to form a protrusion 431, and the protrusion 431 is fixedly connected to the inner side of the upper surface of the side panel 42 of the top seat layer 1, and the protrusion 431 is also flush with the support bar 16 in Example 4, and supports the baffle 18 together with it, and the inner side of each side panel 42 of the connecting layer 2 and the top seat layer 1 is connected with a protective plate 44, and the setting of the protective pad 43 and the protective plate 44 can isolate the base layer 3, the connecting layer 2 and the top seat layer 1 from the internal concrete to avoid sticking to the concrete and being difficult to remove. The bottom of the protective pad 43 extends downward beyond the lower surface of the side panel 42 of the top seat layer 1, and the top of the protective panel 44 of the connecting layer 2 is lower than the upper surface of the side panel 42 of the connecting layer 2. The thickness of the protective panel 44 is greater than the thickness of the protective pad 43. When installing the top seat layer 1, the side panel 42 of the top seat layer 1 is stacked on the corresponding side panel 42 of the connecting layer 2, and its protective pad 43 will extend downward beyond the side panel 42 of the top seat layer 1 and intersect with the side panel 42 of the connecting layer 2 in height and be connected to the protective panel 44 of the connecting layer 2, that is, the top seat layer 1 and the connecting layer 2 are cross-connected. This cross-connection method can make the connection between the top seat layer 1 and the connecting layer 2 more stable.

[0049] Furthermore, adjacent protective pads 43, adjacent protective plates 44, and adjacent protective pads 43 and protective plates 44 are all tightly connected, that is, the protective pads 43 in the adjacent side panels 42 of the top seat layer 1, the protective plates 44 in the adjacent side panels 42 of the connecting layer 2, and the protective plates 44 in the adjacent side panels 42 of the base layer 3 are all tightly connected. Similarly, the upper and lower sides of the protective plates 44 of the connecting layer 2 are also tightly connected to the corresponding protective pads 43 of the top seat layer 1 and the corresponding protective plates 44 of the base layer 3, respectively, to prevent the concrete from flowing out from the gaps at the connections before solidification, causing concrete loss and damaging the outer components. The top surface of the protective plate 44 of the connecting layer 2 is flush with the inner side of the connection point of the protective pad 43 of the top seat layer 1, and the bottom surface of the protective plate 44 of the connecting layer 2 is flush with the connection point of the protective plate 44 of the base layer 3, which is conducive to maintaining a good shape of the concrete after solidification and can also prevent concrete loss.

[0050] Furthermore, the inner walls of the protective pad 43 and the protective plate 44 are coated with an anti-adhesion coating. The anti-adhesion coating is made of polymer coating or silicate coating. The use of the anti-adhesion coating can better solve the problem of easy adhesion of concrete.

[0051] Furthermore, the casting cavity 41 in the connecting layer 2 and the top seat layer 1 is a cylindrical cavity, and the casting cavity 41 in the base is a truncated cone cavity with an upper bottom area smaller than a lower bottom area. By setting the upper part of the casting cavity 41 to be cylindrical and the bottom to be truncated cone, it is more conducive to the concrete pile solidifying into a standard shape after casting.

[0052] Example 6: Based on Example 1, the connection method of the connection layer 2 is preferably designed, such as Figure 3 As shown, a number of vertically arranged connecting rods 20 are evenly fixed along the circumferential direction at the bottom of the connecting layer 2, and an annular groove 31 is provided at the top of the base layer 3. The movable end of the connecting rod 20 extends into the annular groove 31 to provide limited support for the connecting layer 2. When installing the connecting layer 2, the position of the side panels 42 of the connecting layer 2 can be adjusted at any time so that adjacent side panels 42 can be closely connected. During adjustment, the connecting rod 20 slides in the annular groove 31 to keep the side panels 42 of the connecting layer 2 stably connected to the base layer 3.

[0053] Example 7: Based on Example 1, the base layer 3 is preferably designed as follows: Figures 1 to 2 As shown, the base layer 3 is also connected to the heat dissipation layer 32 in the circumferential direction, that is, each side plate 42 of the base layer 3 is fixedly connected with a section of the heat dissipation layer 32. The heat dissipation layer 32 is a block structure made of aluminum and heat-resistant plastic. Its shape matches the connection of the base layer 3. By providing the heat dissipation layer 32, the overall weight of the base layer 3 can be reduced, the separation effect is convenient, and the internal concrete can be better promoted to conduct heat and dissipate heat to the outside.

[0054] Furthermore, the outer side of the bottom of the base layer 3 protrudes outward to form a bottom plate 33. That is, a section of the bottom plate 33 is integrally fixed to the bottom of each side plate 42 of the base layer 3. A number of handles 34 and ground spikes 35 are arranged on the bottom plate 33. The handles 34 and ground spikes 35 are evenly arranged around the circumference of the bottom plate 33. When installing the base, the side plates 42 of the base are first spliced ​​together so that the adjacent protective plates 44 in the base are tightly connected. Then, the ground spikes 35 are struck to move them downward. The cooperation between the ground spikes 35 and the ground is used to fix the base layer 3 and to position the entire casting device. The base layer 3 can be removed by pulling out the ground spikes 35 upward. After the base layer 3 is secured, the connecting layer 2 and the top seat layer 1 are installed one by one. Since the side panels 42 of the base layer 3 and the top seat layer 1 are fixed in position by connectors, and the connecting layer 2 is located between the base layer 3 and the top seat layer 1 and maintains a stable connection with both, the side panels 42 of the connecting layer 2 can be kept in position without other connectors. An annular groove is provided at the bottom of the base layer 3, and a bottom block 36 is embedded in the groove. By further separating the side panels 42 of the connecting layer 2, it is easier to remove the base layer 3.
