after the position of a water conservancy pipeline to be supported is determined, a worker places a bottom plate 3 of a supporting mechanism on the ground where the supporting position is located, communicates the output end of an air pump with one end, which is close to the T-shaped hole 32, of the air pump, starts the air pump to charge air into one end of the T-shaped hole 32, opens a one-way air inlet valve after the air enters the T-shaped hole 32, and continues to flow, so that the air enters the groove 31 through the T-shaped hole 32; the groove 31 is divided into a rod cavity and a rodless cavity by the piston plate 4, the rod cavity is the cavity with the extension plate 5, gas generated by the air pump can enter the rodless cavity, so that the piston plate 4 is pushed to slide in the corresponding groove 31, the two piston plates 4 are far away from each other, the piston plate 4 can drive the corresponding extension plate 5 to move far away from each other, the extension plate 5 can extend out of the corresponding groove 31, the extension plate 5 and the bottom plate 3 are supported on the ground together, and as the bottom plate 3 increases the contact area with the ground, according to the formula P=F/S, the pressure born by the ground is reduced, the situation that the support mechanism cannot sink even when the support mechanism supports a water conservancy pipeline is avoided, after the extension plate 5 extends out of a limit position from the groove 31, the air pump is stopped, the connection between the output end of the air pump and the T-shaped hole 32 is released, and then the water conservancy pipeline is supported on the upper end face of the supporting plate 1;
after a worker places a bottom plate 3 in a supporting mechanism on the ground to be supported, the worker steps on the bottom plate 3 by feet, holds a supporting plate 1 by hands, controls the supporting plate 1 to press down, drives a connected sliding rod 23 to move down, drives a piston disc 22 to move down while the sliding rod 23 moves down, the piston disc 22 extrudes a lower cavity, the lower cavity is communicated with one end, which is close to a T-shaped hole 32, of the lower cavity, gas in the lower cavity enters two grooves 31 along the T-shaped hole 32 after being extruded, then holds the supporting plate 1 and controls the supporting plate 1 to move up, the supporting plate 1 moves up to drive a connected sliding rod 23 to move up, the sliding rod 23 moves up and drives a piston disc 22 to move up, so that the lower cavity can form negative pressure, external gas can enter an upper cavity, the gas in the upper cavity opens a one-way valve on the piston disc 22 and enters the lower cavity along a one-way air inlet hole 221, so that the external gas can be filled into the grooves 31, and the piston 4 is pushed to move away from each other by the action of air pressure; in the embodiment, the space of the lower cavity is larger than the sum of the spaces of the two rodless cavities, the gravity generated by placing the water conservancy pipeline on the supporting plate 1 is utilized to drive the transfer of gas, and the process that the extension plate 5 extends out of the groove 31 can be completed only by pressing down once; in the process of the piston plate 4 being pressed downwards, the spring 24 can be compressed to complete the force accumulation process, and when a worker stops pressing the piston downwards, the spring 24 can push the piston to upwards move, so that the worker only needs to press downwards in a unidirectional way in the gas injection process; the two piston plates 4 are far away from each other, so that the air pressure in the rod cavity is increased, the air pressure in the rod cavity enters the round hole 36 along the first hole 37, the expansion bag 7 is finally expanded, the expansion bag 7 fills the soft space between the bottom plate 3 and the ground, the expansion bag 7 is sunk into the soft ground after being expanded, the expansion bag 7 gives the bottom plate 3 an upward buoyancy force, the downward force born by the supporting mechanism is balanced as much as possible, the sinking probability is reduced, and the air pressure in the rod cavity is reduced or even negative pressure is formed in the process of mutually approaching the two piston plates 4, so that the expansion bag 7 is shrunken under the action of self-contraction force or negative pressure; after the supporting mechanism is placed on the soft ground, the bags are inflated and pressed to expand, so that a plurality of inflated bags 7 uniformly give upward buoyancy after being inflated, and rollover is avoided; after the supporting mechanism is placed on the harder ground, the plurality of expansion bags 7 are compressed and expand, and the air pressure among the plurality of expansion bags 7 is communicated, after one expansion is blocked by the ground, the other expansion bags 7 with gaps with the ground continue to expand, so that the gaps between the bottom plate 3 and the uneven ground are filled by the expansion bags 7; after the supporting mechanism is placed on the soft ground, the expansion bag 7 is pressed and expanded, and the expansion force given to the expansion bag 7 is insufficient to overcome the elasticity of the second tension spring 82 because the expansion bag 8 is connected with the bottom of the chute 38 through the second tension spring 82, so that the expansion bag 7 plays a role in the soft ground when the sliding plate 8 and the conical rod 81 are in an unopened state; after the supporting mechanism is placed on the harder ground, the expansion bag 7 is pressed and expanded to be in contact with the ground, and then cannot be continuously expanded, so that gas in the rod cavity can enter the chute 38, the tension of the second tension spring 82 is overcome, the gas pressure pushes the sliding plate 8 to move away from the bottom of the chute 38 along the chute 38, the conical rod 81 is pushed to be inserted into the ground in the sliding process of the sliding plate 8, the purpose of firmly locking the bottom plate 3 on the ground is achieved, after the two piston plates 4 move close to each other, the pressure of the rod cavity is reduced, the sliding plate 8 moves close to the bottom of the chute 38 under the action of negative pressure and the tension of the second tension spring 82, and the conical rod 81 is retracted into the chute 38; in the process that the slide plate 8 drives the conical rod member 81 to be inserted into the ground, the conical rod member 81 rotates forward under the transmission of the threads of the hole with the internal threads on the hole plate 83, so that the conical rod member 81 is easier to be inserted into the ground, and in the process that the slide plate 8 drives the conical rod member 81 to move close to the bottom of the chute 38, the conical rod member 81 rotates reversely under the guidance of the hole plate 83, so that the conical rod member 81 is pulled out from the ground and retracted into the chute 38;
in the process of injecting air into the groove 31, firstly, the sliding section in the sliding rod 23 is contacted with the through hole 211, so that a worker drives the supporting plate 1 and the sliding rod 23 to move up and down to drive the piston disc 22 to reciprocate up and down, if the worker feels that the movement resistance of the piston disc 22 is large, the spiral transmission can be switched, namely, the threaded section in the sliding rod 23 is contacted with the through hole 211, and the supporting plate 1 is held to drive the sliding rod 23 to rotate, so that the spiral transmission of the threaded section in the screw rod in the through hole 211 is realized, and the sliding rod 23 is driven to reciprocate up and down in the process of reciprocating the sliding rod 23, so that the sliding rod 23 drives the piston disc 22 to reciprocate up and down; before the water conservancy pipeline is placed in the supporting plate 1, the air channel 11 plays a role in balancing the air pressure of the upper cavity and the outside, after the water conservancy pipeline is placed in the inner side of the supporting plate 1, the water conservancy pipeline can squeeze the sealing ring on the inner side of the supporting plate 1, so that the periphery of one end of the air channel 11 is sealed, then the threaded section in the sliding rod 23 is rotated, the sliding rod 23 moves downwards, the height of the water conservancy pipeline can be adjusted, the sliding rod 23 which moves downwards drives the piston disc 22 to move downwards, the space of the upper cavity is enlarged due to the downward movement of the piston disc 22, negative pressure is formed in the upper cavity, the air at one end of the air channel 11 is sucked by the upper cavity, the water conservancy pipeline is firmly adsorbed in the inner side of the supporting plate 1 under the action of the negative pressure, the water conservancy pipeline is prevented from sliding from the supporting plate 1 in the installation process, and the adsorption force to one end of the air channel 11 can be reduced and relieved by reversely rotating the threaded section in the sliding rod 23;
the supporting mechanism can be used as a permanent supporting water conservancy pipeline, and can also be used as a temporary supporting water conservancy pipeline, when the extension plate 5 is required to be retracted into the groove 31, only the rotating block 6 with the rotating button is required to be rotated, so that the rotating block 6 rotates in the round groove 33, the pressure relief hole 61 in the rotating block 6 is communicated with the transverse hole 34 after rotating, the transverse hole 34 is communicated with the groove 31, gas in the groove 31 has certain pressure, so that the gas in the groove 31 can be flushed out of the outside along the transverse hole 34 and the pressure relief hole 61, the pressure relief purpose is realized, after the rodless cavity in the groove 31 is relieved to a certain extent, the first tension spring 35 pulls the corresponding piston plate 4 to slide along the groove 31, the two piston plates 4 move close to each other under the pulling action of the first tension spring 35, and simultaneously drives the extension plate 5 to synchronously move, so that the two extension plates 5 are mutually close to each other, the process of retracting the groove 31 is completed, in order to avoid the extension plate 5 from taking sludge into the groove 31, the rod cavity of the groove 31 is provided with the groove 31, and the cross section of the extension plate 5 is consistent with the groove opening of the groove 31, and the groove 5 is set up to the groove opening of the groove 5; when it is desired to push the two piston plates 4 away from movement, the swivel block 6 is rotated so that the relief holes 61 are offset from the transverse holes 34.
