DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the following preferred embodiments are cited with reference to the accompanying drawings and the present invention is further described in detail. However, it should be noted that many details listed in the specification are only for enabling the reader to have a thorough understanding of one or more aspects of the invention, and these aspects of the present invention can be implemented even without these specific details.

[0031] Please refer to Figures 1 to 3 , the present invention provides a permanent and temporary reinforcement method for high-performance materials, and the technical solution is as follows: including the following steps:

[0032] S1. Arrange multiple support columns 1 on the ground into at least two rows, and each row is parallel to each other;

[0033] S2. Fix multiple support columns 1 to the ground. An adjustment mechanism 2 is provided in the support column 1, which can adjust the length of the support column 1;

[0034] S3. Install a support beam 3 on the top of each row of support columns 1, and the support beam 3 penetrates through the tops of multiple support columns 1 in the same row;

[0035] S4. A plurality of support rods 4 are provided between two adjacent support beams 3;

[0036] S5. The upper parts of multiple support rods 4 cooperate with each other to support the wall body 5.

[0037] In the present invention, by setting the support column 1, the support beam 3 and the support rod 4, multiple support rods 4 support the wall body 5, the support beam 3 supports multiple support rods 4, and the support column 1 supports multiple support beams 3, so that the weight of the wall body 5 is gradually unloaded until the support column 1, improving the stability of the support, and the vibration during construction also gradually decreases to the wall body 5, reducing the disturbance to the wall body 5 during construction. Further, an angle steel 13 is provided below the wall body 5, and the angle steel 13 abuts against the support rod 4 to reduce the wear below the wall body 5. The support column 1, the support beam 3 and the support rod 4 are made of steel structures, preferably high-strength low-alloy steel or tool steel, such steels have high strength, strong shear resistance and tensile and compressive resistance, so as to improve the stability of the overall mechanism.

[0038] As a specific embodiment of the present invention, the support column 1 includes a first support portion 101 for connecting to the ground and a second support portion 102 connected to the support beam 3. An installation cavity 103 is provided inside the first support portion 101, and the second support portion 102 is slidably connected in the installation cavity 103. The top of the second support portion 102 passes through the top of the installation cavity 103 and extends to the outside of the installation cavity 103; an adjustment mechanism 2 is installed at the bottom of the second support portion 102. The second support portion 102 moves in the first support portion 101, thereby changing the length of the support column 1 to cope with the situation where the wall body 5 has different heights or the ground at the bottom of the same wall body 5 is not on the same horizontal line, and changing the lengths of different support columns 1 according to the height of the ground at the bottom of the wall. To ensure that the support beam 3 is located on the same horizontal plane 10, and at the same time, the adjustment mechanism 2 is used to relatively fix and relatively move the first support portion 101 and the second support portion 102.

[0039] Further, the adjusting mechanism 2 includes a pneumatic cylinder 201. One end of the pneumatic cylinder 201 is connected to the bottom of the installation cavity 103, and the other end abuts against the bottom of the second support portion 102. When the pneumatic cylinder 201 is ventilated, the top of the second support portion 102 moves upward, thereby increasing the length of the support column 1; conversely, when the air pressure is released, the second support portion 102 moves downward under the action of gravity and air pressure, thereby reducing the length of the support column 1. The pneumatic cylinder 201 preferably can also use a pneumatic jack to save space.

[0040] Still further, an air release hole 202 is provided on the cylinder body of the pneumatic cylinder 201. An air release plug 203 is rotatably connected to the outside of the cylinder body of the pneumatic cylinder 201. A plug hole 204 matching the air release hole 202 is provided on the air release plug 203. The air release plug 203 can rotate to change the position of the plug hole 204, so that the plug hole 204 coincides with or separates from the air release hole 202. The air release hole 202 can reduce the gas pressure in the pneumatic cylinder 201 slightly to increase the elasticity of the second support portion 102, which can buffer vibrations and further reduce the disturbance to the wall 5 during construction. When releasing air, it is necessary to twist the air release plug 203 to align the air release hole 202 with the plug hole 204. Thus, the gas in the pneumatic cylinder 201 is ejected under the action of gas pressure. Then, rotate the air release plug 203 again to separate the plug hole 204 from the air release hole 202 to close the pneumatic cylinder 201. A sealing rubber ring can also be installed on the peripheral side of the air release plug 203 to improve airtightness and prevent gas from spraying out between the air release plug 203 and the steel wall of the pneumatic cylinder 201.

[0041] Still further, a rotating handle 205 is installed at one end of the air release plug 203 away from the pneumatic cylinder 201. The rotating handle 205 extends outside the installation cavity 103. The rotating handle 205 facilitates rotating the air release plug 203 outside the installation cavity 103 to reduce the operation difficulty of the device.

[0042] As a specific embodiment of the present invention, a monitoring hole 206 is provided on one side of the pneumatic cylinder 201. A monitoring channel 207 is provided inside the monitoring hole 206. The monitoring channel 207 communicates with the inside of the pneumatic cylinder 201. A pressure gauge 208 is connected to the end face of the monitoring hole 206. The air inlet hole of the pressure gauge 208 communicates with the monitoring channel 207. The pressure gauge 208 passes through the cavity wall of the installation cavity 103. When in use, the gas in the pneumatic cylinder 201 enters the pressure gauge through the detection channel, and the pressure gauge displays the air pressure value. This setting enables the outside to directly observe the air pressure inside the pneumatic cylinder 201 and prevent the risk of explosion caused by excessive air pressure.

[0043] As a specific embodiment of the present invention, a sliding groove 6 is provided on the top of the support beam 3, and fastening holes 7 are provided on the sides of both ends of the support rod 4. Fasteners 8 are threadedly connected in the fastening holes 7, and the fasteners 8 pass through the fastening holes 7 and enter the sliding groove 6. The support rod 4 can move on the support beam 3 to target different ground surfaces of the wall 5, which is more conducive to the dispersion of the pressure of the wall 5 to increase stability. The fasteners 8 are used to fix the support rod 4, and the movement of the fasteners 8 in the slide groove can prevent the displacement of the support rod 4 relative to the vertical direction of the slide groove, making the support more stable.

[0044] Furthermore, a rotating block 9 is provided at one end of the fastener 8 away from the support beam 3; the rotating block 9 is cylindrical; and a plurality of planes 10 are arranged in a ring on the side of the rotating block 9. The rotating block 9 can conveniently rotate the fastener 8, and the plurality of planes 10 arranged in a ring can conveniently grasp the rotating block 9 for rotation.

[0045] As a specific implementation of the present invention, this embodiment also uses a diagonal brace 11 as a lateral support for the wall 5, one end of the diagonal brace 11 is connected to the wall 5, and the other end is connected to the ground. To prevent the wall 5 from overturning. The angle between the diagonal brace 11 and the ground is preferably 45°, the axial force (along the rod direction) and the horizontal / vertical force are equal, and the material utilization rate is the highest; the angle between the diagonal brace 11 and the ground can also be selected to be 30° to 45° to enhance the ability to resist lateral displacement.

[0046] As a specific implementation of the present invention, this embodiment also uses a scaffold 12 to support the concave bottom surface of the wall 5, one end of the scaffold 12 is connected to the support rod 4, and the other end is connected to the side wall of the concave. This setting can support the overly large concave bottom of the wall 5 to improve stability.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
