Head, intake tunnel top connects a high-pressure water pipe, and high-pressure water pipe connects high-pressure pump；
Step 2, by step one improve drill steel be inserted in described well casing, on drill steel annular chuck be pressed on well casing
On iron plate, starting quartering hammer, quartering hammer drives drill steel to shake downwards iron plate, and the crushing shell of iron plate bottom crushes ground；
Step 3, startup high-pressure pump, the water under high pressure that high-pressure pump pump produces enters into shower nozzle from intake tunnel, and shower nozzle sprays earthward
Penetrating water under high pressure, broken up by soil, along with well casing moves down, the mud that water under high pressure produces is discharged to well from exhalant canal automatically.
Preferably, in step 2, also include that utilizing the vibration of quartering hammer to first pass through drill steel breaks soil layer harder for ground
Open, utilize the step of drill steel penetrated surface.
The invention has the beneficial effects as follows: relative to prior art, this device is applicable to the dewatering well that bore is bigger, once
Pressure is pulled out and is got final product disposable Cheng Jing, and shrinkage cavity will not occur, and working procedure is few, simple to operate, quick, utilizes this kind of mode to have only to one
Two staff are the most operable, and efficiently, expense is low, simple and convenient, are greatly shortened the down tube time, complete a underground and bury
Pipe was not over one hour.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Enlarged drawing at A in the present invention of Fig. 2 position.
Detailed description of the invention
Below in conjunction with the accompanying drawings and preferred embodiment describe in detail the present invention detailed description of the invention.As it is shown in figure 1, a kind of well
Pipe, including water level monitoring pipe 1 and ferrule, the lower loop week of described water level monitoring pipe with permeable hole, described ferrule by
Iron plate 2 with holes and iron pipe 3 are constituted, and described iron pipe is enclosed within described water level monitoring pipe and affixed with it, described iron plate and institute
Stating iron pipe affixed, the external diameter of described iron plate is more than the external diameter of described iron pipe, and the internal diameter of described iron plate is interior less than water level monitoring pipe
Footpath, is provided with crushing shell 4, the tip shaped of described crushing shell in the lower loop week of described iron plate.
In the present invention, described water level monitoring pipe is tubing or permeable corrugated tube 5.Described tubing is wrapped with filter course.
For filtering subsoil water, concrete structure is, described filter course is sponge 6 and geotextiles 7, and described sponge wrapping is described
Outside water level monitoring pipe, described geotextiles is wrapped in outside described sponge.
In the present invention, permeable corrugated tube is also a modification of the present invention, makes traditional corrugated tube into permeable nonwoven
Cloth.Owing to corrugated tube can shrink, thus, take up room the least, the lightest, during construction, drill steel is inserted into ripple
The lower end of pipe, drives corrugated tube to move, and corrugated tube upper end is fixed, and such corrugated tube can slowly extend in well.
As in figure 2 it is shown, present invention also offers a kind of method for burying well casing,
Its embedment underground comprises the following steps:
Step one, first traditional quartering hammer is improved, have an annular chuck 9, drill steel in drill steel 8 end of quartering hammer
