Abstract

The invention provides an automatic air supplying device for a manual hole digging pile well. The automatic air supplying device comprises air supplying equipment, air draft equipment, a ventilation pipeline, a well interior fixing plate, a ground fixing support, well interior fixing supports, a gas detector and a control background; the ventilation pipeline is divided into an air supplying pipeline and an air draft pipeline, and the gas detector is arranged on one side of an air outlet of the air supplying pipeline; the well interior fixing plate is vertically fixed to the well wall, and themultiple well interior fixing supports are arranged on the well interior fixing plate; the ventilation pipeline is in a 7 shape constituted by a horizontal section and a vertical section, the horizontal section is fixed to the ground through the ground fixing support, and the vertical section is fixed to the well interior fixing plate through the well interior fixing supports; and down-hole poisonous and harmful gas can be monitored in real time through the ventilation pipeline and the gas detector, when the poisonous gas exceeds the standard or the well interior air quality does not reach thestandard, gas exchanging can be quickly and circularly conducted in the well, and occurrence of safety accidents caused by the fact that the poisonous and harmful gas exceeds the standard is effectively reduced.

Description

technical field [0001] The invention relates to a monitoring air supply device, in particular to an automatic air supply device for manually digging pile wells. Background technique [0002] During the construction of manual hole-digging piles, various types of "toxic and harmful gases" may be generated inside. Various toxic and harmful gases produced by underground biogas or soil humus. Underground biogas is often found in areas surrounded by silt, peat, coal mines, landfills, etc. It is mainly toxic and harmful gases such as methane deep in the formation, which is not conducive to the safe operation of underground workers. Soil humus will also produce various toxic and harmful gases due to complex chemical and biological reactions, which seriously threaten the life safety of underground operators. Therefore, before and during the operation of manual hole-digging piles, real-time monitoring of toxic and harmful gases in the underground is carried out, and the operation ca...
