Simple well drilling tools and methods, the simplest manual well drilling method

Portable hole opener, one-inch iron water pipe (no more than meters, two ends with silk teeth, a number of direct, a number of pipes), a water pump, a number of water outlets.

The simplest method of hand-drilling is as follows:

1. Location selection.

First of all, it is necessary to determine a good location: a living water source, a large soft space, and a slightly higher location than the home location.

2. Determination of well depth.

The position next to the well and the deep mountain should be able to determine the stability of the water source, and the height of the well depth can be excavated after the determination, and the water can be stored with cement after the 2 measurements are completed, and the upper side is best fixed with a stone to maintain stability.

3. Cement fixation and manhole cover.

The prepared depth can be fixed with cement, pay attention to the position of the lower part 3 7 in the fixing process, and after the manhole cover cement is fixed, you can leave an area that can be entered, so as to be used for cleaning in the later stage.

4. Water storage. After the cement is dry, you can start to store water, the first storage can be a little less, so that the reservoir flows and keeps it clean, or you can store water for 2 days and then release the water and start storing water again to ensure the amount of water you need.

5. Pay attention to adding purifiers to household water.

For the household water part, you can add an external purifier, and then use it after the water is purified, and pay attention to check the water in the well to ensure that there is no leakage area.

Hello dear, I am glad to answer for you: the whole process of drilling a small well drilling machine is as follows: The first step:

After being equipped with a suitable pump into a well, it is necessary to calculate the dynamic and static water level of the well and the appropriate water output according to the construction irrigation situation during the ploughing, and then according to the height difference from the ground to the moving water level and the irrigation method you use, the total head of the pump must be confirmed by the working head of the pump, and the flow rate of the pump is not much up to the water flow of the well. Step 2: Reasonable wellbore layout The orientation layout of the wellbore should be based on the actual local hydrogeological conditions.

In areas where shallow groundwater is not very abundant, shallow wells should never be drilled blindly; In areas where shallow groundwater is abundant, it is suitable for farmers to be shallow wells, but the arrangement of the wells in Tsai Qing Song cannot be too dense, so as not to lead to the interaction between adjacent water source wells. Step 3: Use accurate construction methods There are two construction methods for large wells:

The first is the large slotting method, manual excavation or blasting construction; The second is the caisson method, irrigation construction or non-irrigation construction. In the construction of the counter-pumping type, two methods of mechanical hammer and manual hammer are generally used, and the gravity of the hammer is used to drive the soft pipe into the ground.

The determination of the well site is mainly to find the right spring, to find the water song: two mountains between a mouth, there must be water underground, the gravel belt is watery, the red stone is dry under the bangbang, the bay to the bay, the mouth (refers to the mountain mouth) to the mouth, the long flowing water, etc.

It is mainly said that the borehole should generally be arranged at the foot of the ridge-like middle hill, hilly valley, depression or weathering fracture development and the junction between weathering fracture and tectonic fracture. The skill of professional drilling techniques is to judge different waterlines according to different formations.

Find water according to the characteristics of the terrain:

1. "It is most advantageous to find water". Surrounded by mountains on three sides, groundwater flows to Pukekou in a concentrated manner, so wells are drilled near Pukeikou, and the amount of water is more.

2. "Two mountains are sandwiched by a ditch, and there is a water flow in the ditch rock". Sandwiched between the two mountains is a ravine, and water sources are easily found in the rock formations on both sides of the lower valley.

3. "Two ditches intersect, spring water surging".

At the intersection of the two ditches, there may be a spring water flowing under the mouth of the mountain, and the water source is more reliable when a well is drilled here. And to achieve the purpose of finding water. The first thing that is used to pump groundwater is that after the rainwater falls to the ground, part of it seeps into the ground and accumulates in the cracks of the soil and rocks, which becomes groundwater.

The amount of groundwater is related to lithological structure, topographic and geomorphological conditions and recharge**. Therefore, the experience of the masses in finding water is specially introduced, and the farmers in drought-prone areas are found to find water sources and dig wells.

1. The iron pipe that can be held with one hand can also be cut off and then processed into several short iron pipes by the lathe, which is convenient for connection during construction.

2. Dig a small pit with a shovel on the ground first, then pour some water in the pit, and then put the iron pipe made in advance vertically into the pit, and then lift it hard, and then press the iron pipe hard, so that the operation is repeated until the iron pipe is drilled to the appropriate water layer about 10 meters underground, during which water should be continuously added to the pit, so that the work is faster.

3. Then the iron pipe is raised, and a borehole will appear on the ground, and a plastic pipe or iron pipe will be put into the borehole (the middle pipe wall should not leak), and then the ground borehole will be sealed, and then you can install a vacuum pumping device at the upper end of the pipe, or a pressurized water wellhead, or a piston and tie rod reciprocating in the pipe, and the underground water will continue to pour to the ground.

To realize the function of tap water in their own wells, they generally need to assemble a pumping machine, and then match a few water pipes, so that they can realize the function of tap water, and when you want to use water, you can directly turn on the power supply of the pump, and then there will be water pumped up, which is the same as the principle of tap water.

Pumps are also known as "pumps". A centrifugal water pump is a hydraulic machine that uses atmospheric pressure to lift water from a low place to a high place. It consists of a water pump power machinery and a transmission device.

It is widely used in farmland irrigation and drainage, as well as water supply and drainage in industrial and mining enterprises and towns. There are many types to suit different needs.

Well water is artificially drilled from the ground and can be divided into shallow well water and deep well water

Shallow well water is infiltrated from rainwater and above-ground silt water, which may have some unclean impurities, while deep well water flows from the water veins in the earth's crust, with many mineral contents, such as excessive iron and manganese, which affects our normal use, at this time we can install a filter, but what filter is suitable for well water depends on the specific situation.

Tool. 1. Percussion drilling tools. Including drill bits that directly crush borehole rock formations, there are drum bits, slotted bits, cross bits, round bits, angle cone bits, etc.

One end of the percussion drill pipe is connected to the drill bit, and the other end is connected to the wire rope. Wire rope joints include live core wire rope joints, live ring wire rope joints, open live core wire rope joints, reducer joints, as well as drilling tool wrenches and ratchet rotators, and dredging cylinders for slag removal and mud dredging cylinders for removing cuttings in holes.

2. Rotary drilling machine. Includes:

a. Lifting the faucet. A key component that connects the drilling well to the mud pumping line, etc. The main function of the slag is to lift all the drilling tools and rotate with all the drilling tools; The second is to send the mud into the bottom of the well through it and the rotary drill pipe to achieve the purpose of promotion.

b. Square drill pipe. There are threaded connections at both ends, and a square core structure is provided on the turntable. When drilling, the square drill pipe is inserted into the square core, and the turntable rotates the square drill pipe to drive the drill pipe and drill bit to drill.

c. Drill bit and joint. Drill bits are divided into comprehensive drilling bits (double-wing fishtail bits, three-wing scraper bits, cone bits, spiral step bits), corn drills and ring drill bits (cobalt grain drill bits, cemented carbide drill bits); Large-diameter core pipes (rock transportation core pipes, core pipe joints, powder pipes) and auxiliary equipment (wire ropes, winch drums, slides, lifting tools, jacks) and other tools.

Method. There are two methods of construction for large wells:

1. Fierce and quiet large slotting method, manual excavation or blasting construction;

2. Caisson method, drainage construction or non-drainage construction.

In the construction of the counterpart pumping type, two methods of mechanical hammer and manual hammer are generally adopted, and the suction pipe is directly driven into the ground by the gravity of the hammer.
