Pipe-inserting negative pressure air jet deep-well dewatering device
The invention discloses a pipe-inserting negative pressure air jet deep-well dewatering device. The pipe-inserting negative pressure air jet deep-well dewatering device comprises a negative pressure system, a positive pressure system and a deep well structure, wherein the negative pressure system is provided with a vacuum sub water pipe; the positive pressure system is provided with a sub air pipe; the deep well structure consists of a sand well, a filter pipe and a clay wellhead; the sub air pipe of the positive pressure system penetrates through the connector of the vacuum sub water pipe of the negative pressure system and extends into the vacuum sub water pipe; the vacuum sub water pipe is connected with the filter pipe; and at least one connector is arranged on the vacuum sub water pipe. According to the pipe-inserting negative pressure air jet deep-well dewatering device disclosed by the invention, the deep well structure consisting of the sand well, the filter pipe and the clay wellhead is adopted, and a well pipe is omitted, so that the layered dewatering and excavating of a deep foundation pit are facilitated; normal operation of an excavator is not affected; and the pipe-inserting negative pressure air jet deep-well dewatering device has the advantages of high working efficiency, easy construction and good dewatering effect.
