[0002] With the development of society, the demand for clean energy has gradually increased. Solar energy is not only simple and easy to obtain, but also sustainable and will not suffer from energy depletion problems, thus having broad application prospects. The construction of bored cast-in-place piles in photovoltaic power stations is to fabricate and install the base for photovoltaic supports, which is the foundation of photovoltaic construction.

[0003] The bored cast-in-place piles in photovoltaic power stations mainly drill pile holes in the foundation through a drilling rig, place pile structures into the drill holes, and pour concrete to form pile foundations. The photovoltaic support columns and pile foundations are connected in an insertion manner to complete the installation of photovoltaic supports.

[0004] Currently, the commonly used formwork for support pile foundations is steel formwork and fiberglass formwork, both of which need to be customized and processed in a professional processing factory in advance. In addition, during formwork installation, the fixing frames and fasteners need to be repeatedly disassembled and tightened, resulting in long installation and disassembly times and relatively high reinforcement costs. At the same time, since the formwork is composed of at least two pieces, there are many cylindrical joints, increasing the subsequent processing work at the joints.

[0005] Therefore, this application provides a rapid installation and disassembly formwork device for photovoltaic support pile foundations to improve the formwork installation and disassembly efficiency and reduce the workload of subsequent joint treatment. Summary of the Utility Model

A U-shaped buckle is rotatably installed on the pressing handle. A buckle groove for cooperating with the U-shaped buckle is provided on the buckle seat.

[0011] Preferably, notches corresponding to the tightening mechanisms one by one are provided on some of the hollow corrugations. The steel wire rope passes through the hollow corrugations from the notches, and the buckle is located outside the notches.

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the attached Figures 1-6 Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0031] To solve the problems existing in the prior art, this embodiment provides a rapid installation and disassembly formwork device for a photovoltaic support pile foundation, including a pouring sleeve 1. A number of hollow corrugations 2 are arrayed on the outer wall of the pouring sleeve 1. A longitudinally penetrating longitudinal seam 3 is opened on one side of the pouring sleeve 1. A plurality of tightening mechanisms are arrayed on the pouring sleeve 1 for tightly clamping the end surface of the longitudinal seam 3.

[0032] The tightening mechanism includes a steel wire rope 4 with a diameter of 5 mm, and the two ends of the steel wire rope 4 are connected with a lock 6.

[0033] Principle details of this embodiment:

[0034] A rapid installation and disassembly formwork device for a photovoltaic support pile foundation includes a pouring sleeve 1. A number of hollow corrugations 2 are arrayed on the outer wall of the pouring sleeve 1 to form a double-wall corrugated pipe structure. A longitudinally penetrating longitudinal seam 3 is opened on one side of the pouring sleeve 1. A plurality of tightening mechanisms are arrayed on the pouring sleeve 1 for tightly clamping the end surface of the longitudinal seam 3 of the pouring sleeve 1. The tightening mechanism includes a steel wire rope 4, and the two ends of the steel wire rope 4 are connected with a lock 6. The lock 6 is a prior art, and its structure is like a car hopper lock. The inner wall of the pouring sleeve 1 is smooth and sprayed with a release agent.

[0035] Production process:

[0036] 1) According to the height of the support pile foundation on the drawing, cut a suitable length of double-wall corrugated pipe to make a casting sleeve 1;

[0037] 2) Cut the casting sleeve 1 longitudinally and neatly to form a longitudinal seam 3 running through the top and bottom;

[0038] 3) A set of tightening mechanisms are respectively tied at the longitudinal cuts at both ends and the middle position, the lock buckle 6 is opened, and the tightening mechanism is in a relaxed state;

[0039] 4) Apply demoulding lubricant to the inner wall of the casting sleeve 1 to facilitate demoulding; place a self-adhesive anti-leakage sponge sealing strip at the longitudinal joint 3 to prevent concrete from leaking from the longitudinal joint 3;

[0040] 5) Lock the lock buckle 6, tighten the wire rope 4 so that the incision of the casting casing 1 is tightly closed, and the longitudinal seam 3 is sealed;

[0041] 6) Start pouring;

[0042] 7) When the concrete maintenance of the support pile foundation reaches the design required time, just open the lock 6 in sequence, loosen the wire rope 4, and pull the pouring sleeve 1 upward to separate the pouring sleeve 1 from the pile foundation, thereby completing the pouring operation. After cleaning the pouring sleeve 1, it can be transferred to the next station for pouring.

[0043] The device has a simple structure and only requires a small amount of corrugated pipes, wire ropes 4, and locks 6. It can be processed on the construction site and has a low production cost. It is easy to operate, quick to install and disassemble, and has high work efficiency, which can reduce the labor intensity of workers and shorten the construction period. The material turnover is fast and can be used repeatedly. Only three longitudinal joints may form joints, the number of joints is reduced, the template is neat and standardized, and the pile foundation is well formed, which reduces the workload of later contact processing and effectively reduces the infiltration of concrete from the joints, prevents slurry leakage, and the appearance of the pile foundation can meet the design specification requirements.

[0044] The outer wall of the casting sleeve 1 is provided with hollow corrugations 2, which greatly enhances the ring stiffness of the pipe material, thereby enhancing the resistance of the pipe to soil load.

[0045] In a further embodiment of the present solution, a specific lock buckle 6 structure is provided in the present embodiment: the lock buckle 6 comprises a buckle seat 601, a mounting seat 602, a pressing handle 603, and a U-shaped buckle 605. The buckle seat 601 and the mounting seat 602 are fixedly mounted at both ends of the steel wire rope 4 respectively. The pressing handle 603 is rotatably mounted on the mounting seat 602. The U-shaped buckle 605 is rotatably mounted on the pressing handle 603 and the rotating part is close to the middle of the pressing handle 603. The buckle seat 601 is provided with a buckle groove 606 that cooperates with the U-shaped buckle 605.

[0046] During use, the bent part of the U-shaped buckle 605 is buckled in the buckle groove 606, and the pressing handle 603 is opened. At this time, the steel wire rope 4 is in a relaxed state. Press the pressing handle 603, and the pressing handle 603 pulls the other end of the steel wire rope 4 through the cooperation of the U-shaped buckle 605 and the buckle groove 606, so that the steel wire rope 4 is tightened, thereby locking the buckle 6 to the casting sleeve 1 and closing the longitudinal joint 3.

[0047] In a further embodiment of this solution, a part of the outer wall of a part of the hollow corrugation 2 is cut off to form a notch. The steel wire rope 4 passes through the hollow corrugation 2 from the notch, and the locking buckle 6 is located outside the notch. With this arrangement, the tightening mechanism is contracted inside the hollow corrugation 2 to limit the steel wire rope 4 and prevent the steel wire rope 4 from shifting in the relaxed state, and repositioning is required when using it again.

[0048] In a further embodiment of this solution, the center line of the notch coincides with the longitudinal joint 3. This can not only reduce the number of ports of the hollow corrugation 2 and reduce the impact on the anti-extrusion ability of the casting sleeve 1, but also facilitate observing the closing condition of the longitudinal joint 3.

[0049] In a further embodiment of this solution, the contact surfaces of the buckle seat 601 and the mounting seat 602 with the casting sleeve 1 are both arc-shaped. This makes the contact between the buckle seat 601, the mounting seat 602 and the casting sleeve 1 more sufficient, avoiding stress concentration and abrasion of the casting sleeve 1 due to too small contact area or warping of the contact surface.

[0050] In a further embodiment of this solution, the pressing handle 603 is provided with a jack. A pressing shaft 604 is inserted into the jack. Both ends of the pressing shaft 604 extend out from both ends of the jack. Through holes are provided at both ends of the pressing shaft 604, and the two cantilever ends of the U-shaped buckle 605 are respectively inserted into one through hole. Threads are tapped on the two cantilever ends of the U-shaped buckle 605. Nuts 607 are threadedly installed on the threads of the U-shaped buckle 605, and the nuts 607 abut against the side wall of the pressing shaft 604.

[0051] During use, when the locking buckle 6 is in the locked state, adjust the nut 607 of the U-bolt of the locking buckle 6 (only need to be adjusted when threading the steel wire rope 4 for the first time), tension the steel wire rope 4 passing through the outer wall ring pipe, and close the longitudinal joint 3 of the casting sleeve 1 to meet the needs of pouring concrete. When the subsequent steel wire rope 4 is relaxed, the nut 607 can also be screwed to tension and adjust the steel wire rope 4.

[0052] In a further embodiment of this solution, substrates 5 are welded to both ends of the steel wire rope 4. The buckle seat 601, the mounting seat 602 and the corresponding substrates 5 are all provided with mounting holes, and the mounting holes on the buckle seat 601, the mounting seat 602 and the corresponding substrates 5 are detachably connected by fasteners. Thus, the locking buckle 6 can be disassembled and assembled. By removing the locking buckle 6, the steel wire rope 4 can be inserted through the notch of the hollow corrugation 2, which is convenient for subsequent maintenance and replacement.

[0053] In a further embodiment of the present solution, the casting sleeve 1 has different size types, and its inner diameter is within 200 mm to 3000 mm, which can meet the requirements of different diameter pile foundations of the photovoltaic support.
