Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0017] like figure 1 Shown, a kind of method to the closed precipitation construction of precipitation wellhead in this specific embodiment: comprise the following steps:
[0018] (1) Obtain the protection cover of the wellhead for precipitation. The protection cover for the wellhead of the precipitation includes a circular cover plate 1. The center of the circular cover plate 1 is provided with an equipment placement hole concentric with it. The closing plate 2 that closes the equipment installation hole, the upper surface of the closing plate 2 and the position close to its edge are provided with at least three limit buckles, and the center of the closing plate 2 is formed by connecting all the limit buckles in turn In the polygon, the limit buckle includes a rotating shaft fixedly connected to the closing plate 2, a limiting block 3 is arranged on the rot...

The invention discloses a method for sealing a precipitation well mouth and performing precipitation construction synchronously. The method comprises the following steps: first, acquiring a precipitation well mouth protection cover, mounting the precipitation well mouth protection cover at the precipitation well mouth, and then operating corresponding components of the precipitation well mouth protection cover; placing a cover plate fixing bracket in a precipitation well and fixing the cover plate fixing bracket; next, covering the precipitation well mouth with a circular cover plate, and fixing the circular cover plate on the precipitation well mouth by a connection bolt; rotating a spacing block to enable the spacing block to be far away from the circular cover plate, opening a sealing plate, and placing a submersible pump through a device placing hole to perform precipitation construction in the precipitation well; and after the precipitation construction is completed, taking out the submersible pump, holding a handle to pull the sealing plate, so that the sealing plate is rotated and moved up to seal the device placing hole, and rotating a spacing block to space the sealing plate to complete the cover sealing of the precipitation well. The device placing hole is independently formed in a well cover and is used for placing the submersible pump and allowing a water pump pipeto extend out, the precipitation construction is completed when the precipitation well mouth is sealed, and the construction safety is improved.
Description
technical field [0001] The invention relates to a dewatering construction method of a dewatering well, in particular to a method for dewatering construction of a dewatering well head closed. Background technique [0002] Precipitation engineering refers to the application of hydrogeological principles, through precipitation design and precipitation construction, to discharge surface water bodies and reduce the water level of stagnant water, diving, confined water, bedrock water, karst water and other groundwater in the formation to meet the precipitation depth and Time requirements, and no harmful effects on the engineering environment. In order to ensure construction safety, a protective cover is usually installed at the head of the dewatering well to avoid safety accidents caused by accidental falls of construction workers. However, in the operation of precipitation, it is necessary to open the protective cover and place pumping equipment such as submersible pumps, which ...
