suction pipe 1 is arranged at the bottom of the foundation pit, the top end of the gas pipe 502 is communicated with an air compressor, the top end of the water conveying pipe 402 is communicated with water supply equipment, and when normal mud suction work is carried out, the annular piston 6 is in a state of plugging the, the mud, sand, pebbles and water at the bottom end of the mud pumping pipe 2 flow upwards in the mud suction pipe 1 to generate negative pressure, the mud, sand, pebbles and water at the bottom end of the mud pumping pipe 2 flow upwards by utilizing the negative pressure, and are discharged from the top end of the mud suction pipe 1, when the pipe orifice at the bottom of the mud suction pipe 1 is blocked, namely the mud blocks and the pebbles are clamped at the pipe orifice at the bottom of the mud suction pipe 1, the mud blocks and the pebbles in the mud pumping pipe 2 cannot be discharged by flowing upwards, the mud blocks and the pebbles are clamped at the inclined plane of the mud pumping pipe 2 blocked at the mud suction pipe 1, so that the pipe orifice at the bottom of the water guide hole 201 is blocked, under the condition that the negative pressure is unchanged and no mud blocks or pebbles flow upwards at the bottom of the mud suction pipe 1, the negative pressure above the annular piston 6 in the annular pipe 3 is increased by self regulation, the elasticity of the spring 7 is overcome, and the annular piston 6 moves upwards, so as to open a channel between the water, the water in the water storage ring pipe 4 flows downwards through the water guide pipe 401, the self-adjusting ring pipe 3 and the water guide holes 201, and downwards washes away mud blocks and pebbles blocked in the mud pumping pipe 2 under the action of water pressure, so that the mud blocks and pebbles can be re-pumped by the mud pumping pipe 1, the problems that the pumping efficiency of the mud blocks and pebbles is reduced and the working efficiency and the process are affected due to pipe orifice blockage are effectively solved, after the mud blocks, pebbles and water at the bottom of the mud pumping pipe 2 flow upwards again under the action of negative pressure, the negative pressure above the annular piston 6 in the self-adjusting ring pipe 3 is reduced, the elastic force of the spring 7 enables the annular piston 6 to move downwards to re-block the water guide pipe 401 and the water guide holes 201, and along with the continuous operation of mud pumping, when the water amount in a foundation pit is less and the sludge in the interior is tight and the suction cannot be carried out, and under the condition that no mud blocks and pebbles flow upwards at the bottom of the mud pumping pipe 1, the negative pressure above the, the channel between the water guide pipe 401 and the water guide hole 201 can be opened, so that the water pressure is utilized to spray from the bottom of the water guide hole 201 to loosen the tight sludge in the foundation pit, so that the sludge can be sucked again, the sludge sucking effect is further improved, and the water resource is effectively saved.

Wherein, the top of the self-adjusting ring pipe 3 is hermetically sleeved with a sealing ring, the top of the sealing ring is movably connected with the top of the water storage ring pipe 4, two sides of the bottom of the sealing ring are respectively movably connected with the top ends of two springs 7, and both sides of the bottom of the sealing ring are fixedly connected with a limiting rod 302 positioned at the inner side of the spring 7, the bottom end of the limiting rod 302 is positioned below the through groove 301, the sealing ring is sealed at the top of the self-adjusting ring pipe 3 to ensure that the negative pressure generated by the negative pressure airflow in the mud suction pipe 1 and the same negative pressure is formed above the annular piston 6 in the self-adjusting ring pipe 3, so that when no mud block, pebble and the like flow upwards at the bottom end of the mud pumping pipe 2, the negative pressure above the annular piston 6 in the self-adjusting ring pipe 3 is increased, so that the annular piston 6 can move up to open a passage between the water introduction pipe 401 and the water introduction hole 201, and the limit rod 302 is used for limiting, so that the annular piston 6 after moving upwards can not block the through groove 301.

Wherein, logical groove 301 has all been seted up to the both sides of the junction between self-interacting ring canal 3 and the suction dredge 1, and leads to the internal diameter of groove 301 and by outer to interior even increase, when effectual avoiding mud piece, cobble etc. to flow through logical groove 301, the card leads to the fact the problem of jam in leading to groove 301 department, ensures suction dredge normal clear.

Wherein, the fumaroles 501 of a plurality of intercommunications are seted up to the junction between air guide ring pipe 5 and the suction dredge 1, and the drill way that is located air guide ring pipe 5 inboard fumaroles 501 upwards to one side, the internal diameter total of a plurality of fumaroles 501 is less than the internal diameter total of gas-supply pipe 502, make through air guide ring pipe 5, the air current that fumaroles 501 spout in to suction dredge 1 upwards flows, be favorable to reducing the velocity of flow loss of air current, so that the air current velocity of flow is enough big in suction dredge 1, thereby ensure that the negative pressure below is enough big, can suck bigger clod, silt, improve the suction dredge efficiency.

When the mud suction pipe is used, the top end of the air conveying pipe 502 is communicated with an air compressor, the top end of the water conveying pipe 402 is communicated with water supply equipment, the mud suction pipe 1 is placed in a foundation pit, then the air compressor is started to compress air, the air enters the mud suction pipe 1 through the air conveying pipe 502, the air guide ring pipe 5 and the air jet holes 501, flows upwards in the mud suction pipe 1 to generate negative pressure, mud, sand, pebbles and water at the bottom end of the mud suction pipe 2 flow upwards by utilizing the negative pressure, the mud, sand, pebbles and water are discharged from the top end of the mud suction pipe 1, when a pipe orifice at the bottom of the mud suction pipe is blocked or the mud in the foundation pit is tight, so that subsequent mud, pebbles and the like do not flow upwards in the bottom of the mud suction pipe 1, the negative pressure above the annular piston 6 in the self-adjusting ring pipe 3 is increased, the annular piston 6 is moved upwards by overcoming the elasticity of the spring 7, so that a channel between the, The water guide holes 201 flow out downwards, and under the action of water pressure, mud blocks, pebbles or loose sludge blocked in the mud pumping pipe 2 is flushed downwards, so that the mud pumping pipe 1 can re-pump the mud blocks and pebbles, and after the mud blocks, pebbles and water at the bottom of the mud pumping pipe 2 flow upwards again under the action of negative pressure, the negative pressure above the annular piston 6 in the self-adjusting ring pipe 3 is reduced, and the elastic force of the spring 7 enables the annular piston 6 to move downwards to block the water guide pipes 401 and the water guide holes 201 again.
