Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a well drilled underground, and more particularly to a well that can be dealt with during disaster prevention.

[0002]

[Background of device]

 In recent years, there have been many large earthquakes, especially the Great Hanshin Earthquake that struck Kobe city in Hyogo prefecture and its suburbs, and many victims have been reported every day by TV, radio, newspapers, etc.

[0003]

[Prior art]

 In the past, well water from wells excavated underground was pumped from the ground by hand pumps, tsurubes, etc., but nowadays, it is almost replaced by electric submersible pumps and is conveniently used in normal times. There is.

[0004]

[Problems to be solved by the device]

 However, as is clear from the Great Hanshin Earthquake, once the earthquake hit, the lifeline was cut off, electricity was cut off, and the submersible pump became unusable. Although there is water there, the result is that it cannot be used.

[0005]

[Means for solving the problem]

 In the present invention, in a main well constructed in the ground, an underwater power pump is arranged below the water level of the main well, and a communication pipe that connects the submersible power pump and a ground facility provided near the ground above the main well. In addition to arranging the water well, a supplementary well is constructed by providing a branch below the water level of the main well, and a pumping water supply section is disposed below the water level of the supplemental well. The problem is solved by arranging a communication pipe that communicates with a human-powered pump provided in the vicinity of the ground.

[0006]

[The purpose of the device]

 In view of the above-mentioned problems, the present invention proposes and provides a double well in which another well mouth is constructed in a conventionally used well and water can be pumped up manually in case of disaster. This is the purpose.

[0007]

[Example of device]

 Hereinafter, the dual well for disaster prevention of the present invention will be described in detail with reference to the drawings of the embodiments.

FIG. 1 is a schematic explanatory view of a dual well for disaster prevention according to the present invention.

The present invention relates to a well excavated in the underground A, and more particularly to a well that can be dealt with in the event of disaster prevention. In the main well 1 constructed in the underground A, the main well 1 The submersible power pump 1a is disposed below the water level B of the main well, and the communication pipe 1c for communicating the submersible power pump 1a with the above-ground equipment 1b provided in the vicinity of the main well above the ground is arranged. 1. A branching part 2 is provided below the water level B of 1 to construct a supplementary well 3, and a pumping water supply part 3a is arranged below the water level B of the supplementary door 3 and is connected to the pumping water supply part 3a. A communication pipe 3c is provided for communicating with a human-powered pump 3b provided near the ground above the supplementary well.

That is, as in the embodiment shown in FIG. 1 of the present invention, first, the main well 1 is constructed vertically to the underground A. The construction method, construction equipment, construction materials, etc. of the main well 1 are Well-known methods, well-known devices and materials may be used, and they are constructed by penetrating the flowing water layer of the underground A.

Then, another auxiliary well 3 is similarly drilled in the vicinity of the constructed main well 1 to provide a branch portion 2 below the water level B of the main well 1, and the branch portion 2 The T-shaped tube and the elbow may be connected and used, or a branched tube in which the T-shaped tube and the elbow are integrally formed may be used, or the branch portion 2 may be provided by excavation.

Next, the submersible power pump 1a is disposed below the water level B of the constructed main well 1, that is, in a submerged state, and the submersible power pump 1a and the main well 1 are provided near the ground. A communication pipe 1c that communicates with the above-ground equipment 1b such as a valve and piping provided is provided, the submersible power pump 1a and the ground are electrically connected, and switches and the like are arranged on the ground. It is a thing.

Next, below the water level B of the supplementary well 3, that is, in the submerged state, a pumping water supply unit 3a such as a strainer is arranged, and the pumping water supply unit 3a and the supplementary well 3 are arranged. A communication pipe 3c for communicating with a manual pump 3b such as a hand pump provided near the ground of the supplementary well 3 is provided.

The dual well for disaster prevention of the present invention can be applied to an existing well. The existing well is used as a main well 1, a supplementary well 3 is constructed in the vicinity thereof, and a branch portion 2 is provided below the water level B. It can be carried out by providing a hand pump as a power pump 3b on the supplementary well port of the supplementary well 3 in communication with the main well 1.

The present invention is intended to be used for drinking water, fire protection water, irrigation water, etc. by using the submersible power pump 1a by electric power in normal times, and a hand pump etc. in a power failure state at the time of disaster such as a great earthquake The human-powered pump 3b pumps up groundwater.

[0015]

[Effect of device]

 The present invention constructs a supplementary well near the main well, and has a hand pump near the ground above the supplementary well that can be pumped by human power. It is an epoch-making, highly practical and highly significant effect.
