Abstract

The invention relates to the technical field of construction, in particular to a surface precipitation deep well washing device. The surface precipitation deep well washing device comprises a well washing pipe, a high-pressure air hose and a blowing member. The blowing member is used for blowing high-pressure air to the high-pressure air hose, the high-pressure air in the high-pressure air hose moves upwards through a gap between the inner wall of the well washing pipe and the high-pressure air hose after passing through the bottom, meanwhile, well bottom sediment and water outside the well washing pipe are pushed to the head of the well to a certain height, then, the blowing member is turned off to stop blowing through an air supply pipe, and the blown sediment and water are quickly pushed upwards through the gap between the well washing pipe and the high-pressure air hose due to the siphon phenomenon and ejected out through a sediment discharge opening, so that the purpose of well bottom sediment removal is achieved. The surface precipitation deep well washing device is easy to assemble in site and operate and capable of well removing bottom sediment of a deep well to ensure the effective reduction of the water level of a tunnel.

Description

Technical field [0001] The invention relates to the technical field of building construction, in particular to a deep well washing device for surface water dewatering. Background technique [0002] At present, deep dewatering wells are used in tunnel construction to lower the groundwater level of the mountain in tunnel excavation to facilitate normal tunnel excavation. To build tunnels in sand or other extremely soft rocks, when the groundwater level is relatively high, deep dewatering wells need to be set up on the surface. By draining the water in the deep wells, the water level in the layer where the tunnel is located is lowered below the construction location, but in deep dewatering wells Mud and sand are often deposited at the bottom, which cannot make the precipitation reach the required position. Only after the mud and sand at the bottom of the well can be pumped out can the precipitation work be carried out smoothly. [0003] However, when the dewatering well is deep, the ...
