Abstract

The invention discloses a double-rod discharging device, equipment for controllably releasing shallow harmful gas in a land area and a construction method. The double-rod discharging device comprisesan exploration gas injection feeler lever and a deflation feeler lever; and the exploration gas injection feeler lever comprises a first hollow feeler lever body, a first perforated feeler lever bodyand an exploration feeler lever body which are sequentially connected from top to bottom; and the deflation feeler lever comprises a second hollow feeler lever body, a second perforated feeler lever body and a gyro-type drill bit which are sequentially connected from top to bottom. The equipment for controllably releasing the shallow harmful gas in the land area comprises the double-rod discharging device, a hydraulic loading device, a controllable deflation device, and a gas combustion device; the hydraulic loading device is connected with the double-rod discharging device and provides press-in force for the double-rod discharging device; the controllable deflation device is connected with the double-rod discharging device and is used for controlling the gas release rate; and the gas combustion device is connected with the controllable deflation device and is used for treating the harmful gas. The problems of incomplete gas release and hole site blockage are solved, and the equipmentis suitable for engineering exhaust application.

Description

technical field [0001] The invention relates to the technical field of gas-bearing strata construction, in particular to a double-rod discharge device and equipment and construction methods for controlled release of shallow harmful gases in land areas. Background technique [0002] With the advancement of urbanization, China's urban rail transit has ushered in a new development, but more and more corresponding problems have emerged. In coastal soft soil areas, a large amount of shallow gas is distributed. This is a It is a kind of shallow buried natural gas that is unfavorable to underground engineering construction and harmful to human health. These shallow gases are difficult to identify with conventional survey methods and are very likely to affect the project. If corresponding engineering measures are not taken, future During the construction process, it is easy to form hazards, which will hinder the construction work, affect the normal construction, and seriously affect...
