[0027] See Figures 1 to 3 .

[0028] The formwork device of the present invention for the concrete pouring of the well wall is composed of multiple groups of support formwork units 100. The support formwork unit includes a formwork body 110 and a support mechanism 120. The support mechanism 120 includes a vertical support member 10, a fastener 30, and a horizontal support member 20 fixed on the formwork body 110.

[0029] In the installation state, multiple groups of the support formwork units 100 are sequentially arranged along the circumferential direction of the well wall at the bottom of the well. The formwork bodies 110 of multiple groups of the support formwork units 100 are enclosed and spliced into a circular formwork. The vertical support member 10 is inserted into the ground at the bottom of the well, and the horizontal support member 20 is detachably connected to the vertical support member 10 through the fastener 30.

[0030] The structure of the present invention is simple. Through the support mechanism, the formwork body can be stably supported and installed. After the pouring is completed, as long as the fastener is removed and the vertical support member is pulled out of the ground at the bottom of the well, the disassembly of the support formwork unit can be realized. When it needs to be used again, as long as the vertical support member is re-driven into the soil, the formwork body is set up again, and the corresponding components are connected with the fastener.

[0031] The formwork device of the present utility model is stably supported and installed, and it is not easy to have the problem of formwork displacement during concrete pouring, which can ensure the quality of the well wall concrete pouring. Moreover, it can be disassembled and assembled repeatedly and used cyclically, and the disassembly and assembly are very convenient, greatly improving the simplicity of the workers' operation and reducing the time for removing and installing the formwork support, providing help for realizing the safety, convenience, high efficiency and high quality of construction, and being applicable to the construction of well walls such as inverted wells.

[0032] In one embodiment, the vertical support member 10 includes a vertical strut 101 and a soil nail 102 fixed to the lower end of the vertical strut 101. With such a design, the structure is simple and it is convenient for the vertical support member to be inserted into the bottom ground of the well.

[0033] In one embodiment, in the installed state, the formwork body 110 is arranged in an inclined manner with the top inward. The transverse support member 20 includes a first cross strut 201 and a second cross strut 202. The second cross strut 202 is located below the first cross strut 201 and the length of the second cross strut 202 is greater than the length of the first cross strut 201. With such a design, the first cross strut, the second cross strut, the vertical strut and the formwork body form a trapezoidal structure, and the support is more stable.

[0034] In one embodiment, the fastener 30 is composed of a first hoop and a second hoop connected together. The first hoop and the second hoop are respectively used to hoop around the vertical strut and the first cross strut or the second cross strut. In this way, the transverse support member can be detachably connected to the vertical support member.

[0035] In one embodiment, the first hoop and the second hoop are rotatably connected. With such a design, the angle between the first and second hoops is adjustable and can be adaptively adjusted according to the angle between the vertical strut and the first cross strut or the second cross strut. Specifically, the hoop body 301 of the first hoop and the hoop body 301 of the second hoop can be rotatably connected through a rotating shaft 309.

[0036] In one embodiment, the first hoop and the second hoop have the same structure, and both include a hoop body 301, a hoop body 302, an internal thread sleeve 303 and a locking bolt 304. One end of the hoop body 301 is rotatably connected to one end of the hoop body 302. The internal thread sleeve 303 is connected to the other end of the hoop body 301. A notch 305 for accommodating the locking bolt 304 is formed at the other end of the hoop body 302. In the installed state, the locking bolt 304 passes through the notch 305 and is threadedly connected to the internal thread sleeve 303. This kind of hoop has a simple structure, is easy to manufacture, and is convenient for disassembly and assembly, and the rod member is clamped between the hoop body 301 and the hoop body 302.

[0037] In one embodiment, an installation groove 306 is formed at the other end of the hoop body 301, and one end of the internal-threaded sleeve 303 is rotatably installed in the installation groove 306 through a connecting shaft 307. With this design, the angle of the internal-threaded sleeve can also be adjusted, making it easier to cooperate and connect with the locking bolt.

[0038] In one embodiment, a groove 308 for cooperating with a gasket is formed on the outer side surface of the other end of the hoop body 302. With this design, during installation, a gasket can be sleeved on the locking bolt between the nut and the hoop body 302 to increase the locking firmness. The gasket is snapped into this groove for greater stability.

[0039] In one embodiment, the device is made of steel.

[0040] In specific implementation, the lateral support member is connected to the template body by welding to form an integral whole; the vertical strut and the soil nail are connected by welding to form an integral whole; the adjacent template bodies can also be connected by screws to further enhance the structural stability.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
