Description

  The present invention relates to a manual well digging apparatus capable of arbitrarily selecting a digging means in accordance with the physical strength of an operator and the hardness of soil ground, and a well digging method using the same.

  Conventional well digging means include a variety of mechanical means using hydraulic, hydraulic, electric, heavy machinery, and manual means using T-shaped screws, pinching scoops, hammers, scoops, slide hammers, scissors, etc. Well digging equipment and well digging means are widely used on a daily basis.

  However, the mechanical means in the above increase the size and weight of the device itself, and also have to ask a well digger who has a skillful operation skill and operation qualification for the operation method, and also the well. The digging cost was also high. On the other hand, with manual means, excavation can be performed at a relatively low cost, but the work time is prolonged and the burden of heavy labor is greatly forced.

  As a method for solving the above-mentioned problems, a method of selecting a well digging means using a manual pile driving tool that can be piled with a simple device by one person can be considered.

  As a proposal of the manual type pile driving tool in the above, for example, at least a pair of handle bars are fixed to the outer surface of a straight tubular hammer tube that is long in the vertical direction. A striker having a flat striking surface is fixed to the upper end of the hammer tube. A hammer-cylinder is fitted on the top of the pile, and the pile driving tool is driven down and operated while maintaining the fitted condition, and the pile can be driven by only one operator. "Pile hitting tool" that can perform pile driving work efficiently and safely, such as not causing damage such as chipping or cracking, and avoiding injury of auxiliary workers due to damage (Patent Document 1) Has been proposed and is a known technique.

  In addition, a handle for moving the main body up and down, and a load on the main body on the metal main body with a ceiling that is inserted into the pile and the head of the pile stops at the time of insertion. Form a weight to increase. The above-mentioned handle is formed along the longitudinal direction of the main body at the left and right positions of the main body. It has a structure that forms the above-mentioned weight part concentrically with the main body part, and can hit the pile straight, easily, quickly, and easily without breaking the head of the pile. A “manual pile driving device” (Patent Document 2) that allows a pile to be installed without requiring a step is proposed and has become a publicly known technique.

  However, any proposal using the manual pile driving tool in the above is limited to the function and means for driving the pile into the ground, and does not have the function and means as a well digging device. Furthermore, since the weight adjustment is limited to the weight mounted in the hammer body, there is a problem that the weight adjustment cannot be performed according to the physical strength of the worker and the hardness of the soil ground to be driven.

  Moreover, as a proposal of a manual-type well digging tool, for example, the "punching well digger" (patent document 3) which can take earth and sand into a well digger by wind pressure, and a groundwater is used actively, and water-saving is saved. "Punching well digging tool" (Patent Document 4) capable of achieving the above has been proposed and is a publicly known technique.

  However, none of the proposals for the manual well digging tool described above has been a well digging apparatus having a function capable of arbitrarily selecting a digging means in accordance with the physical strength of the worker and the hardness of the soil ground.

  The present applicant pays attention to the fact that a well digging device that can easily and easily dig wells is not yet provided by users in ordinary households, and that there is a high demand for well water used in home gardens and vegetable gardens. Based on the idea of providing a well drilling device that is inexpensive and easy to use, we developed a manual well drilling device that can adjust the weight according to the physical strength of the worker and the hardness of the soil ground. This leads to the proposal of the “manual well digging apparatus and the well digging method using the same” in the invention.
