Spray head is filled, intake tunnel top connects a high-pressure water pipe, and high-pressure water pipe connects high-pressure pump；
Step 2: drill steel improved in step 1 is inserted into the well casing, annular chuck is pressed in well casing on drill steel
On iron plate on, start quartering hammer, quartering hammer drives drill steel to shake iron plate downwards, and the crushing shell of iron plate lower part is crushed ground；
Step 3: starting high-pressure pump, the high pressure water that high-pressure pump pump generates enters in spray head from intake tunnel, and spray head is to ground
High pressure water is sprayed in face, and soil is broken up, and as well casing moves down, the mud that high pressure water generates is automatically from exhalant canal to well outlet
Out.
It preferably, further include first passing through drill steel using the vibration of quartering hammer to break the harder soil layer in ground in step 2
It opens, the step of using drill steel penetrated surface.
The beneficial effects of the present invention are: compared with the existing technology, the present apparatus is suitable for the biggish dewatering well of bore, primary to press
Pull out can disposable Cheng Jing, shrinkage cavity will not occur, working procedure is few, easy to operate, quick, and one liang is only needed in the way of such
Name staff can be operated, and efficiently, expense is low, simple and convenient, greatly shortens the down tube time, completes a underground buried tube
A hour is not exceeded.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Enlarged drawing in the present invention of the position Fig. 2 at A.
Specific embodiment
With reference to the accompanying drawing and the preferred embodiment specific embodiment that the present invention will be described in detail.As shown in Figure 1, a kind of well
Pipe, including water level monitoring pipe 1 and ferrule have permeable hole a lower loop week of the water level monitoring pipe, the ferrule by
Iron plate 2 with holes and iron pipe 3 are constituted, and the iron pipe covers on the water level monitoring pipe and affixed with it, the iron plate and institute
State that iron pipe is affixed, the outer diameter of the iron plate is greater than the outer diameter of the iron pipe, and the internal diameter of the iron plate is less than the interior of water level monitoring pipe
The lower loop week of diameter, the iron plate is equipped with crushing shell 4, the tip shaped of the crushing shell.
In the present invention, the water level monitoring pipe is tubing or permeable bellows 5.The tubing is wrapped with filter layer.
For being filtered to underground water, specific structure is that the filter layer is sponge 6 and geotextiles 7, and the sponge wrapping is described
Outside water level monitoring pipe, the geotextiles are wrapped in outside the sponge.
In the present invention, permeable bellows is also a modification of the present invention, and traditional bellows is changed to permeable nonwoven
Cloth.Since bellows can be shunk, thus, occupied space is very small, and it is also very light, drill steel is inserted into ripple when construction
The lower end of pipe drives bellows mobile, and bellows upper end is fixed, and such bellows can be extended into slowly in well.
As shown in Fig. 2, the present invention also provides a kind of method for burying well casing,
It is embedded to underground the following steps are included:
Step 1: first improving to traditional quartering hammer, it is provided with an annular chuck 9 in 8 end of drill steel of quartering hammer,
