Description

Technical Field

[0001] This application relates to the technical field of photovoltaic support cast-in-place piles, and particularly to a reusable formwork for the foundation of photovoltaic support cast-in-place piles. Background Art

[0002] As a clean and renewable energy form, the popularity of photovoltaic power generation is increasing day by day. During the installation of a photovoltaic power generation system, the stability of the photovoltaic support is crucial, and the cast-in-place pile foundation is the key link to ensure the stability of the support. In the traditional construction process of cast-in-place piles, plastic corrugated pipe formwork is often used. When constructing with the corrugated pipe formwork, due to insufficient stability, the concrete vibration is not dense, and the appearance quality is poor. At the same time, after the construction of the cast-in-place pile is completed, the corrugated pipe formwork is discarded after being used once, which not only increases the construction cost of the cast-in-place pile, but also has poor environmental friendliness.

[0003] Therefore, how to reduce the construction cost and environmental impact while ensuring the construction efficiency and quality is the main technical problem to be solved in the current construction of the foundation of photovoltaic support cast-in-place piles. Summary of the Utility Model

[0004] In view of the above problems, this application provides a reusable formwork for the foundation of photovoltaic support cast-in-place piles.

[0005] The reusable formwork for the foundation of photovoltaic support cast-in-place piles provided by this application adopts the following technical solutions:

[0006] A reusable formwork for the foundation of photovoltaic support cast-in-place piles includes a grouting sleeve, adjustable supports, and a horizontal detector; a perfusion cavity that penetrates up and down is provided on the inner wall of the grouting sleeve, and the perfusion cavity is arranged along the axial direction of the grouting sleeve; multiple groups of adjustable supports are fixedly arranged on the side wall of the grouting sleeve, and the horizontal detector is fixedly arranged at the end of the grouting sleeve.

[0007] By adopting the above technical solution, when constructing the bored pile of the photovoltaic support, first measure and mark the construction area of the bored pile, drill holes in the marked area, place the grouting sleeve in the hole, and at the same time install the horizontal detector at the end of the grouting sleeve. Adjust the installation angle of the grouting sleeve. The operator observes the horizontal condition of the grouting sleeve through the horizontal detector and adjusts the installation angle of the grouting sleeve until the horizontal detector shows that the end of the grouting sleeve is horizontal. At this time, the grouting sleeve is vertically arranged; then, install adjustable support members on the side wall of the grouting sleeve. The adjustable support members support the grouting sleeve to prevent the grouting sleeve from shaking and shifting; finally, remove the horizontal detector, grout into the grouting cavity from the end of the grouting sleeve until the bored pile of the photovoltaic support is formed; after the bored pile is formed, remove the adjustable support members, pull out the grouting sleeve from the soil layer, so that the grouting sleeve is separated from the bored pile, and the grouting sleeve can be reused; the reusable steel formwork is set, and the horizontal detector is convenient for observing the position state of the grouting sleeve in real time. The adjustable support members are convenient for ensuring the installation stability of the grouting sleeve, preventing the grouting sleeve from shifting, resulting in the bored pile not being able to maintain a vertical state and affecting the installation stability of the photovoltaic support; the grouting sleeve is used multiple times, which is convenient for reducing the waste of the mold and thus reducing the construction cost of the bored pile.

[0008] In a specific feasible implementation, a plurality of fixed seats are arranged on the side wall of the grouting sleeve, and the plurality of fixed seats are evenly distributed on the circumferential side wall of the grouting sleeve. The adjustable support member is fixedly connected to the fixed seat.

[0009] By adopting the above technical solution, the fixed seats provided facilitate the installation of the adjustable support members and are convenient for the adjustable support members to stably support the grouting sleeve.

[0010] In a specific feasible implementation, the adjustable support member includes a first hinge seat, a first rotating rod, and a threaded sleeve; a second hinge seat and a second rotating rod;

[0012] One end of the second rotating rod extends into the end of the threaded sleeve away from the first rotating rod. The second rotating rod is threadedly connected to the threaded sleeve. The other end of the second rotating rod is rotatably arranged on the second hinge seat, and the second hinge seat is fixedly arranged on the ground on the circumference of the grouting sleeve.

[0013] By adopting the above technical solution, when installing the adjustable support member, according to the height of the grouting sleeve protruding from the ground, rotate the threaded sleeve, thread-connect one end of the threaded sleeve with the first rotating rod, rotate the second rotating rod, and thread-connect the second rotating rod with the other end of the threaded sleeve. Then fix the second hinge seat on the ground on the side wall of the grouting sleeve to achieve the support and fixation of the grouting sleeve. By adjusting the lengths of the first rotating rod and the second rotating rod extending into the threaded sleeve, it is convenient to change the length of the adjustable support member, so that the adjustable support member can be stably supported between the ground and the grouting sleeve according to different installation heights of the grouting sleeve, which is convenient to improve the application range of the adjustable support member.

[0014] In a specific feasible implementation, an installation flange is integrally provided at the end of the grouting sleeve. The installation flange is coaxially arranged with the grouting sleeve, and the horizontal detection member is fixedly arranged on the installation flange.

[0015] By adopting the above technical solution, the provided installation flange provides an installation basis for the horizontal detection member, which is convenient to observe the horizontal state of the top of the grouting sleeve through the horizontal detection member, so as to ensure that the perfusion cavity is vertically arranged and improve the pouring quality of the cast-in-place pile.

[0016] In a specific feasible implementation, the horizontal detection member includes a mounting plate and a spirit level; the mounting plate is bolted to the top wall of the installation flange, and the mounting plate is coaxially arranged with the installation flange;

[0017] The spirit level is fixedly arranged on the upper wall surface of the mounting plate, and the spirit level is located at the center position of the mounting plate.

[0018] By adopting the above technical solution, for the provided horizontal detection member, through the coaxial fixed connection of the mounting plate and the installation flange, and at the same time the spirit level is arranged at the center position of the mounting plate, it is convenient to ensure the measurement accuracy of the spirit level, avoid the spirit level deviating from the axis of the grouting sleeve, so as to bring errors to the measurement of the installation position of the grouting sleeve and affect the pouring quality of the cast-in-place pile.

[0019] In a specific feasible implementation, a lifting lug is arranged on the side wall of one end of the grouting sleeve protruding from the soil layer.

[0020] By adopting the above technical solution, after the grouting of the grouting sleeve is completed and the cast-in-place pile is initially solidified and formed, a lifting device can be used to hang the grouting sleeve through the lifting lug, so that the grouting sleeve is separated from the cast-in-place pile, which is convenient for the reuse of the grouting sleeve, thereby reducing the construction cost of the cast-in-place pile.

[0021] In a specific feasible implementation, a scale ruler is arranged on the side wall of the grouting sleeve along the axial direction.

[0022] By adopting the above technical solution, the set scale ruler facilitates the construction workers to observe the embedding depth of the grouting sleeve, so as to control the height of the cast-in-place pile protruding above the ground within an appropriate range, and further ensure the installation quality of the photovoltaic support on the cast-in-place pile.

[0023] In a specific feasible implementation, the side wall of the perfusion cavity is coated with a corrosion-resistant coating.

[0024] By adopting the above technical solution, the set corrosion-resistant coating facilitates avoiding the corrosion of the inner wall of the grouting sleeve by the concrete, thus affecting the service life of the grouting sleeve.

[0025] In a specific feasible implementation, the material of the grouting sleeve is high-strength metal.

After the ground nail passes through the anchor hole, it is nailed into the ground; by adjusting the lengths of the first rotating rod 22 and the second rotating rod 25 extending into the threaded sleeve 23, the length of the adjustable support member 2 can be ensured to be appropriate.
