Abstract
The utility model discloses a kind of ultra-deep drilling tool cutting water section component, it includes the pipe nipple with center flow channels, the oil nozzle coordinated with pipe nipple, wherein described pipe nipple is provided with annular groove and seal in the mating surface with oil nozzle, also include the nozzle and high-pressure water channel being arranged on pipe nipple, wherein described nozzle is conducted by the annular groove with high-pressure water channel, and the utility model can be widely applied to ultra-deep drilling tool.
Description
Technical field
A kind of drilling tool is the utility model is related to, more particularly to a kind of no-dig technique ultra-deep reinforces the upper cutting water group of drilling tool
Part.
Technical background
With the development of urban construction, engineering construction burns the wind.The difficulty and complexity of engineering construction improve constantly, rotation
The depth of spray stake is continuously increased.Small space, no-dig technique are reinforced, and ultra-deep reinforces a kind of trend as municipal construction.
At home in existing no-dig technique foundation consolidating technology, reinforced using whitewashing cutting.The mode of the reinforcing is being applied
Had a great influence in work by the soil body, if soil property is harder, expanded diameter is small, if soil property is softer, expanded diameter is larger.Partly
Because clay is more, whitewashing blocks serious in area.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of new upper cutting water assembly, skill used by it
Art scheme is：A kind of ultra-deep drilling tool cutting water section component, it includes the pipe nipple with center flow channels, the oil coordinated with pipe nipple
Mouth, wherein the pipe nipple is provided with annular groove and seal in the mating surface with oil nozzle, in addition to the spray being arranged on pipe nipple
Mouth and high-pressure water channel, wherein the nozzle is conducted by the annular groove with high-pressure water channel.
The further technical characteristic of the utility model is：
The nozzle is a check valve, and it includes valve body, clamp nut, spring and steel ball.
The upper cutting water assembly also includes being arranged on the gas cap on the outside of nozzle, and turning on gas cap on pipe nipple
Air flue.
The seal is at least provided with 2.
The beneficial effects of the utility model are：
When carrying out no-dig technique churning operation, upper cutting water section component use can first the interior soil body be cut over the ground,
A larger cylinder is formed, reduces the loss of the spray operation cutting soil body.Water is injected into ground, in the soil layer that viscosity is larger
Play a part of the dilutedly interior soil body, be easy to spoil disposal.In churning operation, upper cutting water forms waterwall, is advantageous to lower drilling tool hole
Interior pressure spoil disposal.Upper cutting water uses check valve principle, can push check valve water spray open when in use, when not in use, not influence to bore
Have other functions.Described gas cap is arranged on the outside of nozzle, there is a certain amount of gap between nozzle, right when ensureing gas output
Water jet forms ring protection, avoids it from declining due to the factors spans such as gravity, cutting force.Meanwhile ground Nei Shui, soil can be mixed
Thing is sufficiently stirred, and increases water content, is diluted soil, is easy to spoil disposal.The protection gas of upper cutting water can be fully by ground Nei Shui, soil, water
The mixtures such as mud are stirred, and improve pile quality.

Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
In the embodiment shown in fig. 1, a kind of ultra-deep drilling tool cutting water section component, it includes carrying center flow channels A
Pipe nipple 1, the oil nozzle 2 coordinated with pipe nipple 1, wherein the pipe nipple 1 is provided with annular groove 3 and close on the mating surface with oil nozzle 2
Sealing 4, in addition to the nozzle 5 and high-pressure water channel 6 being arranged on pipe nipple 1, wherein the nozzle 5 passes through the annular groove 3 and height
Pressure flume 6 is conducted, and in the present embodiment, the nozzle 5 is as shown in Fig. 2 be a check valve, it includes valve body 501, clamp nut
502nd, spring 503 and steel ball 504.Without water under high pressure by when, steel ball 504 is pressed on valve body 501 by spring 503, angle coordinate shuts,
Environmental liquids are blocked to pour into；Water under high pressure is squeezed into, and steel ball 504 is opened on top, is sprayed from clamp nut 502, and now spring 503 is in pressure
Contracting state.In the present embodiment, the seal 4 is provided with four, can also be arranged to two or three in actual applications.This
In actual applications, water under high pressure squeezes into upper cutting water section to embodiment from B mouths, by high-pressure water channel 6, annular groove 3, from nozzle 5
Spray.
Fig. 3 is the structure sectional view of another embodiment of the utility model, and in the present embodiment, the upper cutting water assembly is also
Gas cap 7 including being arranged on the outside of nozzle 5, and the air flue 8 turned on gas cap 7 on pipe nipple 1.The present embodiment is in reality
In, water under high pressure squeezes into upper cutting water section from B mouths, is sprayed by high-pressure water channel 6, annular groove 3, from nozzle 5.Gas is from C
Mouth is squeezed into, and by air flue 8, the annular gap formed between gas cap 7 and nozzle 5 is projected, and is formed ring protection gas, is enclosed in water
Around post.
Fig. 4 is the schematic diagram of embodiment illustrated in fig. 3 working condition, it is seen that ring protection gas bag enclose water column ejection, the two with
Other media of center flow channels are without influence.
Those skilled in the art will be understood that above-described embodiment is illustrative and not restrictive.In different embodiments
The different technologies feature of middle appearance can be combined, to obtain beneficial effect.Those skilled in the art are in studying accompanying drawing, explanation
On the basis of book and claims, it will be understood that and realize the embodiment of other changes of disclosed embodiment.Some skills
Art feature appears in be not meant to reconfigure to be formed by these technical characteristics in different dependent claims
Other embodiment, to obtain beneficial effect.The utility model covers all essence on literal or under the teaching of equivalents
On all technical schemes for being intended to fall within the scope of the appended claims, the scope of protection of the utility model is defined by claims.
