The utility model discloses an adjustable EMS face massage instrument which comprises an adjustable fixing support and massage bodies, ear hooks are arranged on the two sides of the support respectively, massage bodies are further arranged at the tail portions of the two ends of the support respectively, and adjustable structures are arranged between the support and the massage bodies and between the support and the ear hooks respectively. A controller is arranged on the rear side of the adjustable fixing support, the controller is electrically connected with the massage body, an original existing face massage instrument fixed in a mask mode or a face clamping mode is replaced with a face massage instrument fixed in an ear hanging mode, and meanwhile an adjustable structure is arranged on the adjustable fixing support and the massage body. Secondly, ear hooks are further arranged on the two sides of the adjustable fixing support respectively, the relative positions of the ears and the head are different, the ear hooks are adjusted through an adjustable structure, and the adjustable fixing support can be used for adjusting the position of the massage body relative to the human face and controlling the position of the massage face. The structure of a human body is better met, and fitting is closer.

The application discloses a kind of precipitation well plugging construction methods, comprising: inserting precipitation pipe into precipitation well, filling sealing element between precipitation pipe and precipitation well;Steel casing bottom end is sleeved on the top of precipitation pipe, and steel casing and precipitation pipe are blocked with waterproof mortar, precipitation;Laying a layer of cushion on the outer periphery stratum of steel casing, laying concrete layer on the cushion, and reserving to be plugged groove on the outer steel casing of concrete layer;Precipitation pump is extracted, and sand and stone aggregate is filled into precipitation pipe;After checking no backwater, draining the accumulated water in steel casing, and filling into impermeable concrete again;Covering concave steel plate on the top of steel casing;If leakage backwater, carry out hole operation to precipitation pipe through valve body, and inject cement double liquid slurry into hole;Impermeable concrete is used to fill the to-be-plugged groove.This precipitation well plugging construction method and precipitation well plugging structure can effectively solve the problem of well plugging water gushing without quality hidden danger and easy operation.

The application discloses a steel belt cutting dust removal and recovery device and a dust removal method, which comprises a welding unit body for cutting the steel belt, an adjusting mechanism for driving the welding unit body to move is arranged outside the welding unit body, the steel belt is arranged in the middle of the adjusting mechanism, a dust removal mechanism for absorbing cutting dust is arranged above the steel belt, and the dust removal mechanism comprises a dust collection cover for covering the welding unit body and cutting points, soft film is adopted in the application, the surface of the steel belt is slightly concave and convex, the soft film is closely attached to the surface of the steel belt under the cooperation of water and the soft film in the water tank, the water in the water tank can be circulated to absorb heat, the soft film is prevented from being scalded by the high-temperature steel belt, a grinding roller is used for grinding cutting burrs to prevent the soft film from being scratched, the quality of the cutting product is improved, and the possibility of the workers being scratched when the workers transfer the steel plate is reduced.
