In the embodiment, the air suction end comprises an air inlet receiving end 4 connected with the corrugated air cylinder 1 and an air inlet 6 arranged on the air inlet receiving end 4, and the air inlet receiving end 4 is provided with an air inlet valve piece 2 which can open or close the air inlet 6 along the air inlet; the air suction port 6 can be a connecting pipeline, the air suction port 6 is tightly contacted with the opening of the steel column base plate 14, the air inlet valve clack 2 is arranged at the connecting part of the air inlet bearing end 4 and the air suction port 6, and under the action that the external air pressure is greater than the pressure difference of the internal air pressure of the cavity, the air inlet valve clack 2 can be converged towards the air suction port 6 and generates upward thrust to push open the air inlet valve clack 2. The air intake valve clack 2 is mostly made of rubber materials, only one end of the air intake valve clack 2 is needed to be fixed at the air intake bearing end 4, the rest parts are not fixed, and the air intake valve clack 2 can be naturally attached to the air intake 6 by utilizing the vertical downward gravity of the air intake valve clack 2 to form a state of closing the air intake 6. Of course, the intake valve piece 2 may be made of other materials and may be provided on the intake air receiving end 4 so as to be rotatable along the connecting end. When the external air pressure is greater than the internal air pressure of the cavity, the air inlet valve flap 2 is easily pushed open by the external air flow, air bubbles enter the cavity of the corrugated air cylinder 1 through the air inlet bearing end 4, the air pressure in the cavity of the corrugated air cylinder 1 is increased, after the air pressure in the cavity of the corrugated air cylinder 1, the external air pressure at the air inlet 6 and the expansion of the corrugated air cylinder 1 reach the limit, the air inlet valve flap 2 restores to the original state to cover the air inlet 6, and thus, the air suction pump finishes one air suction process from the opening of the steel column base plate 14.

After an air suction port 6 of the air suction pump is tightly contacted with the opening of the column base plate which is polished smoothly, the compressed air suction pump is released, and a key cap at the top of the air suction pump is not under the action of upper pressure and is under the action of the extension of a spring II 11 below the key cap, so that an air outlet valve flap 3 can completely block an air outlet 7; the spring I10 in the cavity of the air pump corrugated air cylinder 1 can extend without the action of the upper pressure, so that negative pressure is generated in the cavity, because the air suction port 6 is tightly contacted with the opening of the steel column base plate 14, some residual air bubbles are left at the lower part of the opening of the steel column base plate 14, under the action of the external air pressure greater than the pressure difference inside the cavity, the air will converge to the air suction port 6 and generate upward thrust to push open the air intake valve flap 2, residual air bubbles at the lower part of the air suction port 6 enter the cavity of the corrugated air cylinder 1 to increase the air pressure in the cavity, the air suction is stopped along with the extension of the spring I10 in the cavity of the corrugated air cylinder 1 reaching the limit, after the air pressure in the cavity of the corrugated air cylinder 1 is balanced with the external air pressure at the air suction port 6 and the elastic force of the spring, the air intake valve clack 2 will recover to cover the air intake 6, so far, the air pump completes one air exhaust process from the opening of the steel column base plate 14. The black solid arrows in fig. 3 indicate upward release of pressure and the hollow arrows indicate upward flow.
After the air pump finishes one air pumping process from the opening of the steel column base plate 14, after downward pressure is applied from the pressing cap 12 at the top of the air pump, the spring II 11 below the pressing cap 12 is compressed and contracted, so that the air outlet valve 3 leaves the air outlet 7; the spring I10 in the cavity of the corrugated air cylinder 1 of the air pump is contracted under the action of upper pressure, and because the air in the cavity of the corrugated air cylinder 1 is compressed at the same time, the generated air pressure presses the air inlet valve 2 to the air inlet 6, so that the lower parts of the air inlet 6 and the opening of the steel column base plate 14 do not generate gas or grouting material to flow; under the condition that the air pressure in the cavity is continuously compressed, when the air pressure is higher than the pressure at the air outlet 7, the air in the cavity is automatically discharged from the air outlet 7, and when the spring I10 in the cavity of the corrugated air cylinder 1 is compressed to the limit, the air pump finishes a top exhaust process. As shown in fig. 4, the solid black arrows indicate downward pressure, and the hollow arrows indicate upward discharge of the air flow from the air outlet 7. The spring type air pump performs a complete air pumping and exhausting process, and the reciprocating circulation is performed, so that the purpose of exhausting residual air bubbles on the contact surface of the steel column base plate 14 and the grouting material is achieved.
In the embodiment, the springs I10 are three and are uniformly distributed along the cavity of the corrugated air cylinder 1; the stability is better.
In this embodiment, the magnet is disposed along the edge of the air inlet to be in close contact with the steel pillar base plate 14, and the magnet is disposed to facilitate the close contact between the air inlet 6 and the opening of the steel pillar base plate 14. During evacuation, the steel stub base plate 14 can be tapped appropriately gently to oscillate the air bubbles at the interface between the slurry and the base plate. Because the air suction pump sucks air from the exhaust holes 15 to generate negative pressure, the slurry and residual air bubbles flow to the exhaust holes 15 until the slurry and the residual air bubbles are discharged from the exhaust holes 15, meanwhile, the slurry around the steel column base plate 14 can gradually sink, and when the slurry does not sink any more after sinking to a stable stage, the air suction can be stopped until the residual air bubbles are discharged.
