before the device is used, the device is moved to the position below an engineering facility to be supported through universal wheels, a power supply is switched on, a control panel is opened, a first electric air pressure rod is opened through the control panel, a second mounting plate is driven to ascend through the first electric air pressure rod, the second mounting plate is ascended to the position below the bottom surface of the engineering facility, a motor is opened through the control panel, a second sliding block on a rotating disc slides in a first annular sliding groove on the second mounting plate, so that the rotating disc rotates, a rotating shaft and the rotating disc on the rotating shaft are driven to rotate through the rotation of the motor, the rotating disc is rotated to the position where an included angle is formed between the second electric air pressure cylinder on the rotating disc and the bottom of the engineering facility, the second electric air pressure cylinder is opened through the control panel, two groups of second electric air pressure cylinders are controlled to push a connecting block to move for different distances, so that the, so that the supporting plate and the horizontal plane form a certain included angle, the supporting plate is adjusted to the same angle with the bottom surface of the engineering facility, the two groups of second electric pneumatic cylinders are controlled by the control panel to move for the same distance, the angle of the supporting plate is unchanged, the height of the supporting plate rises, the supporting plate rises to the position which is completely attached to the bottom surface of the engineering facility, so that the supporting device for civil engineering construction can completely attach the surfaces which need to be supported by different engineering facilities, the stress area between the supporting plate and the engineering facility is greatly increased, the supporting effect is better, when the supporting plate generates supporting force for the engineering facility, the second spring is stretched, the second connecting rod drives the universal wheel to rotate, the first electric pneumatic rod is controlled by the control panel to continuously rise, the base is contacted with the ground, and under the elastic action of the second spring, the universal wheel provides a part of supporting force for equipment, the area that makes this strutting arrangement for civil engineering construction bottom stress point form greatly increased to make the device more stable, in the in-process that first electronic pneumatic rod rises, through stop gear's effect, make after first electronic pneumatic rod atress time overlength and lose tension, the device still can play the supporting role.

8. The working method of the supporting device for civil engineering construction according to claim 7, wherein: the limiting mechanism comprises a first mounting plate, a through hole, a second chute, a fourth slider, a U-shaped limiting block, a threaded hole, a first spring, a second annular chute, a third slider, a rotating rod and threads, wherein the first mounting plate is internally provided with the through hole, the limiting rod penetrates through the through hole, one side of the top of the first mounting plate, which is far away from the first electric air pressure rod, is provided with the second chute, the second chute is internally provided with the fourth slider, the top of the fourth slider is provided with the U-shaped limiting block, one side of the top of the first mounting plate, which is far away from the first electric air pressure rod, is provided with the limiting block, the limiting block is internally provided with the threaded hole, one side of the limiting block, which is close to the first mounting plate, is provided with the first spring, one end of the first spring, which is far away from the limiting block, is connected with the U-shaped limiting block, one, two groups of third sliding blocks are arranged in the second annular sliding groove, a rotating rod is arranged on one side, away from the second annular sliding groove, of each third sliding block, threads are arranged on the outer side, close to one end of each third sliding block, of each rotating rod, and the width of a notch of each U-shaped limiting block is larger than the diameter of each limiting block and smaller than the size of the outer end of each movable block;

in the process that the first electric air pressure rod rises, the third spring is compressed through the elastic action of the third spring when the movable block on the limiting rod passes through the U-shaped limiting block, so that the movable block is pushed into the groove, the limiting rod can rise along with the second mounting plate, after the movable block passes through the U-shaped limiting block, the movable block is pushed out of the groove again under the elastic action of the third spring, so that the limiting rod and the second mounting plate rise together in the rising process of the first electric air pressure rod, and when the first electric air pressure rod loses tension, the movable block on the limiting rod is limited through the U-shaped limiting block, so that the second mounting plate and the support plates on the second mounting plate cannot excessively fall down, the support for the engineering facilities is continuously kept, the safety of the support device for engineering construction is greatly improved, and when the support is finished, pulling the dwang through the handle, make the dwang drive first mounting panel to the direction removal of keeping away from first electronic pneumatic rod, slide in second annular chute through the third slider, make the screw thread rotate, rotate the dwang through the handle, make the screw thread rotate and get into the threaded hole, screw thread through on screw hole and the dwang is mutually supported, make the dwang fix in the threaded hole, thereby make first mounting panel relieve spacing and fixed to the gag lever post, thereby make first electronic pneumatic rod descend, through the first electronic pneumatic rod of control panel control decline relieve the support to engineering facility.
