The such as method of stone post.Corresponding system the invention further relates to can perform methods described.
Background technology
The main target of most of soils improved technology is compacting soil and/or improves its drainability.Exist some
Technology realizes this point, but the present invention relates to set up gravel post in soil.This can be backfilled generally through gravel is combined
The technology of so-called vibrofloation realize that gravel backfill results in stone post.
Vibrofloation is directed to use with vibration probe, and vibration probe can be penetrated downwards wants improved soil up to the depth for needing.
Vibration probe is penetrated into the depth of needs by the jet action of vibration and air.The vibration of probe makes soil texture collapse or quilt
Shift onto on one side, so as to be compacted surround the soil of probe.
Gravel is introduced in the way of post in the presence of two basic skills.First is commonly referred to " top feeding " method, its
In the annulus around probe in including dropping to ground before only gravel is shifted onto at ground level.But, using top
Feeding method, it is impossible to control whether gravel is actually reached the bottom of probe.
Nowadays, second method is referred to as " bottom feeding ", and it is most universal appointed, because it makes it possible to ensure that gravel
Stone is actually disposed at the bottom of probe and compacting.When using bottom signal feed technique, gravel, the pipe are added by pipeline
Road is substantially referred to as following (follow up) pipeline, and it is extended downwardly always beside vibration probe along vibration probe.Gravel
Therefore outlet is placed directly within below vibration probe.Then by the way that continuous gravel batch is fed to, probe is following to produce gravel
Stone column, each batch was compacted before next batch is fed by probe.Column diameter can change, and this depends on the initial hardness of soil
Or density.It is possible that, it is allowed to more gravel is placed in weaker soil region.The stone post of acquisition not only increases compacting
Amount, but also a certain degree of reinforcing and potentially effective draining means are provided.
When using bottom signal feed technique, the head tank for gravel is usually located at the top for following pipeline.Then may be used
Gravel is fed to from this tank in following pipeline.Gravel stockpile is usually located on ground.Gravel must in some way from this
Individual stockpile is transported to the head tank on the top for following pipeline.The method for most commonly using includes using skip bucket, in ground level
Place's back-acting shovel or loading machine are filled to skip bucket, and then rise skip bucket and be emptied into following the top of pipeline
In the head tank at place.But, this method is troublesome, and shortcoming is that can produce some dust, and this causes pollution increase.
Another method for carrying out this point is (to be referred to as letting out from the reservoir at ground level by gravel by using forced air
Batch can) it is transported to head tank.But, gravel is not easy to be transported by air, and due to gravel accumulates in transfer pipe, often
Obstruction occurs.
It is related to actually gravel is fed in soil in another difficulty of the method for known generation gravel post.Especially
It is that the end that pipeline is followed in the case of bury or silt earth is easily blocked by earth materials, this can hinder and present gravel
It is sent to the operation in soil.

The rotary speed of flow of fluid medium is controlled.Rotation of the amount of the gravel sent in each batch by screw rod in each circulation
Numerical control system.
Fig. 1 shows the system for setting up gravel post of first embodiment of the invention.Only display and understanding phase of the present invention
The element of pass.Thus, vibrator probe is for example eliminated in the figure.The gravel supply of such as storage tank 101 is hereinafter referred to as
Reservoir 101, it is used to store gravel and liquid transfer medium, such as water.Show reservoir 101 in Fig. 2 and 3 in greater detail.
Just outside reservoir 101, it is shown that motor 103, it is used to run screw rod, and screw rod is used to for gravel to be fed to feed pipe
In 105.Feed pipe 105 is connected to gravel and liquid feeding device (such as pump in the vicinity (in this example) of reservoir 101
106) on, gravel and liquid feeding device are arranged to gravel and liquid feeding or are pumped into receiving tank or knockout drum (below
Referred to as separate hopper 107) in or directly feed or be pumped into the outlet for leading to soil.In some embodiments, pump 106 soaks
Not in water, and in reservoir 101 below the water surface.Pump can be located under such as horizontal plane in sea, river, lake or pond
Face so that the supply of liquid medium causes that liquid medium need not be circulated.Reservoir 101 can be placed on barge, and will
Pump 106 be immersed in it is marine, for example cause pump be located at reservoir 101 below.Thus, pump can have is used for the gravel from reservoir
An entrance, and for for example from sea water another entrance.
In hopper 107 is separated, gravel is set to be separated with liquid transfer medium, then by one or more appropriate returns
Pipeline 109 makes liquid transfer medium return to reservoir 101.Separating technology is illustrated in further detail below.It is not to return to liquid
To reservoir, but discardable liquid.This can be submerged in water for such as reservoir 101, for example, be placed in seabed or be suspended on and refute
Situation on ship.The purpose of separating technology is only to discharge excessive liquid from hopper 107 is separated, because otherwise it can be rapidly
Fill up.The scope of liquid feed rate can be 4000 to 8000 liters/min, and for example separate hopper 107 capacity can for 1 to
3m3.Yet it is not desirable to separate all liq from gravel.
If the situation that wherein set up the soil of gravel post is too soft, and needs to prevent in the bottom of gravel feed pipe
End sucks soil, then need another tank 111, and it is hereinafter referred to as can pressurized canister.
Granular materials may separate hopper 107 and can pressurized canister together with some liquid and then by gravity by being located at
The first valve 113 between 111 from separate hopper 107 be transferred to positioned at separate below hopper 107 can pressurized canister 111.Can pressurize
The capacity of tank 111 is more than the capacity or at least identical for separating hopper 107.Can pressurized canister 111 can pressurize, such as below will in more detail
As elaboration.
Gravel may together with some liquid from can pressurized canister 111 pipeline 114 is followed by gravity fed to vibration probe
The outlet conduit 115 (hereinafter referred to as gravel pipeline 115) on side, or pipe is directly followed into vibration probe by the second valve 401
In road 114, the second valve 401 is located at can be at the bottom of pressurized canister 111 (referring to Fig. 4 a and 4b).If for example using " gate " type
Valve, then the second valve be alternatively can be below pressurized canister 111 nearby, such as the valve as shown in the first valve 113.In showing for showing
In example, its distal end (away from can pressurized canister 111 end) place's pipeline 114 with vibration probe is different from gravel pipeline 115,
Gravel pipeline 115 is used to be fed to gravel in soil.The two pipelines are parallel to each other and extend to soil.In other constructions
In, gravel can follow pipeline 114 to fall directed along vibration probe, then beside vibration probe, i.e. only in the distally of component
Turned at (bottom) section.
In Fig. 1, compressor 117 is also show, it is used to manufacture compressed air, and compressed air can be by pressure pipeline
119 are directed to gravel pipeline 115.Can pressurization inlet be arranged at the top of gravel pipeline 115, below the second valve 401.Can add
Pressure medium can be compressed air or liquid, such as water.In the case of a liquid, and depending on application, flow control can be used,
Instead of Stress control.
If wherein to set up the situation of the soil of gravel post so that the suction of soil and the bottom end in gravel pipeline
The obstruction at place is not problem, then need not the valve 401 of pressurized canister 111 and second.In this case, gravel pipeline 115 can
It is connected directly between below the first valve 113, or if not using the first valve 113, then gravel pipeline 115 is directly connected to separating material
On bucket 107.
Fig. 2 and 3 shows reservoir 101, and Fig. 2 is perspective view, and Fig. 3 is top view.Can such as see from these figures that
Sample, reservoir 101 in this illustration includes two compartments：For the first compartment 201 of gravel, and for the of liquid
Two compartments 202.These compartments are separated by wall 203.The purpose of wall 203 is to make opening 207 without gravel and cause only to work as screw rod
When feeder system 205 stops, liquid can be flowed freely.Because the opening for screw feed system 205 in wall 203 does not hinder
Only liquid enters first compartment 201, so the gravel in first compartment 201 can partly be submerged.But, this is not problem.
Motor 103 is arranged to drive screw feeder system 205, and screw feed system 205 is arranged to by wall 203
From first compartment 201 be fed in second compartment 202 gravel by one opening, and is more specifically fed to positioned at second compartment
Opening 207 (the second opening 207) at 202 bottom, shows in such as Fig. 3.Feed pipe 105 is connected to this in running status
On individual second opening 207.Thus, gravel and the liquid as transfer medium are arranged at the bottom by reservoir 101
Leave reservoir in opening 207.
Can determine that how many gravel are transferred to feed pipe 105 by each turn of screw rod.Thus, by the rotation for calculating screw rod
Number, can be accurately determined gravel amount.From in terms of quality control viewpoint, compared with the solution of prior art, this point is actually
It is the remarkable advantage of this method, in the solution of prior art, gravel amount fills up several by hopper or back-acting shovel scraper bowl
Control, they may not be to fill or equably fill all the time.Spiral shell is adjusted by the liquid flow with respect to opening 207
The rotary speed of bar, can control the density of " liquid and gravel " mixture.
The one of the method for setting up stone post is explained in more detail referring now to the flow chart of Fig. 1 to 4a and 4b and reference picture 5
Individual example.In step 501, the first valve 113 and the second valve 401 are closed.Once carried out this, then in step 503, can be right
Gravel pipeline 115 pressurizes.If the second valve 401 is opened, this also illustrate that can pressurized canister 111 be also pressurized.Now in step 505
In, open pump 106 and be fed in separation hopper 107 with by liquid (being in this illustration water).In step 507, horse is opened
Up to 103, to rotate screw rod 205 and so as to gravel to be fed in separation hopper 107.In other words, gravel pump together with water
It is sent in separation hopper 107.Hopper 107 is separated now is filled with gravel.
In step 509, it is separated from water gravel in hopper 107 is separated.This separation can be by using one or many
Individual screen is carried out, and screen can be simple net.In the example of Fig. 4 a and 4b, it is shown that separate two inside hopper 107
Inclined screen 403.Gravel is arranged to be advanced on the surface of sieve, and water is fallen by sieve, to be fed out separating hopper 107.
If desired, can adjust the gradient of screen 403.As shown in Fig. 4 a and 4b, it is further provided liquid guide member
405, it can be only plate, and water is directed in return duct 109, to be fed back to reservoir 101 (step 511).These
The purpose of plate 405 is lain also in and prevents gravel from being divided in the possible rotary motion separated inside hopper 107 due to gravel and water
From the moved upward inside of hopper 107.To also it is possible that be separated from water gravel by gravitational settling, in this case use
In the return outlet of return duct 109 will be located at the upper part for separating hopper 107.It is not to feed water in step 511
Return to reservoir 101, but discardable water.
In step 513, it is determined whether the gravel of the amount of needs is sent into separation hopper 107 from reservoir 101.
If not sending the amount of needs also, technique continues in step 509.On the other hand, if sending the amount for needing, in step
Motor 103 is closed in 515, to stop being fed to gravel in separation hopper 107.In step 517, it is determined that all gravels for sending
Whether stone is received at separation hopper 107.Because feed pipe 105 may be more long, in last batch from reservoir 101
Some delays are there may be between the moment that the moment of transmission and this batch are received by separation hopper 107.If not receiving institute
There is gravel, then repeatedly the step is received until all gravels.Once all gravels are received at separation hopper 107, then work
Skill continues in step 519：The first valve 113 is opened so that be fed to can pressurized canister 111 from hopper 107 is separated by gravel by gravity
In.
In step 521, it is determined that can pressurized canister 111 whether be full.If can pressurized canister 111 be discontented with, repeat this
Step.If on the other hand, can pressurized canister 111 be full, then technique continues in step 523, closing the first valve 113.Herein
Afterwards, in step 525, the second valve 401 is opened.Display in fig. 4b is in the second valve 401 of open mode, wherein, second
Valve 401 is in lower position.Now, gravel can by gravity from can pressurized canister 111 be fed in gravel pipeline 115, with feed
To in soil.
In step 527, it is determined that can pressurized canister 111 whether be empty.If can pressurized canister be not empty, repeat this
Step.If this tank is empty, in step 529, the second valve 401 is closed.In fig .4, the second valve 401 of display is in
It closes situation.In all times, at least one of two valves are remained turned-off.This makes it possible to gravel pipeline 115 all the time
In pressurization.This effect having is the operation for promoting to be fed to gravel in soil.In this illustration, the second valve 401 is
Cone valve, it is arranged to move up and down.When display is in upper position in such as Fig. 4 a, valve is closed.From step 529,
Technique continues in step 519.
From step 523, technique also continues in step 531.In this step, it is determined whether need more gravels
Complete gravel post.If necessary to more gravels, then technique continues in step 507.If on the other hand, in step 531,
It is determined that not needing more gravels, then in step 533, pump 106 and the pressurization to gravel pipeline 115 are closed.In the step
Afterwards, method terminates.It should be noted that step 531 and step 525 parallel running.
Above process can be changed in many ways.For example, in hopper 107 is separated, there may be sensor, to measure
Gravel amount in that tank.Once separating the gravel that hopper 107 accommodates desired amount, then this sensor can send signal to
Motor 103, to close it.And, the feeding of gravel from reservoir 101 can be after the first valve 113 be closed immediately again
Start, or in some embodiments, gravel can be fed in separation hopper 107 while the first valve 113 are opened.
As discussed above, the purpose of the first valve 113 and the second valve 401 is to enable to make gravel pipeline 115 protect all the time
Hold pressurization, at the same enable gravel continuous from separate hopper 107 be sent to can pressurized canister 111 (the first valve 113 is opened, at this moment
Second valve 401 is closed), then from can pressurized canister 111 be sent to gravel pipeline 115 (the first valve 113 be closed, the second 401 dozens, valve
Open).Thus, the overvoltage relative to surrounding environment is remained in gravel pipeline 115.To achieve it, pressure entrance
(pressure pipeline 119 is connected on gravel pipeline 115 in this place) is located at below the second valve 401.It is continuously on the work with shutoff valve
Skill is repeated in a cyclic way so that in the illustrated example, and gravel is fed in the way of batch.And, the behaviour of valve 113,401
The operation of the screw feed system 205 at work and reservoir 101 is synchronous.But, it is also feasible that having such solution
Scheme：Wherein, gravel is continuously fed in separation hopper 107 from reservoir 101.But, in that case, gravel feeding
Speed should be slow enough, to avoid wasting gravel due to too fast filling separation hopper 107.
In superincumbent description, describing system can pressurized canister 111 including a separation hopper 107 and one.With
In the related Fig. 6 of two embodiments, it is shown that some parts of dual element, wherein inter alia, component includes two points
Can pressurized canister 111 from hopper 107 and two.In this drawing, suspension device 601, such as pulley be also show, with for example, by
Component is risen or fallen using crane.As illustrated, suspension device 601 is located at the height for separating hopper 107, but
It is far below the top surface 603 for separating hopper 107.This arrangement has specific advantage：It is located at wherein suspension device 601 and is divided
Solution from the top of hopper 107 is compared, and the total height of component becomes smaller.Due to dual element, even if arrangement
Balance is remained in that after suspension device 601 is inserted between separation hopper 107.
In dual element, both sides (side include a separation hopper 107 and one can pressurized canister 111) be independent.
Both sides can run simultaneously or can unsynchronized revolution.For example, when hopper 107 is separated in side filling, can be emptied in opposite side can
Pressurized canister 111.But, in dual element, it is also feasible that side only uses when opposite side is defective.From can pressurize
The gravel pipeline 115 of tank 111 can be merged into single pipeline, or the pipeline 115 of two separation can extend in parallel to soil.And
And, there may be a single feed pipe 105 for each side, or alternatively, for both sides there may be only one it is public enter
Pipe material 105.In the case of the latter, the circulation of both sides is synchronous or feed pipe 105 is equipped with valve, with correlation time
Stream is directed to associated tank.In the case of common feed pipeline 105, it is also feasible that the position of feed pipe 105 can be from one
Opposite side is changed in lateral incision, to be fed to both sides when necessary.In that case, the gravel flow reality from reservoir 101
Can be continuous on border.
As described above, the method according to the first and second embodiments of proposition is consisted essentially of using liquid (substantially
It is water) gravel is transported to separation hopper 107 upwards from ground level, most of liquid is then isolated from gravel, with
And abandon liquid or make liquid recycle, this depends on field conditions.Then be retained in the gravel separated in hopper 107 can feed
To can pressurized canister 111, can pressurized canister 111 can be pressurizeed together with following gravel pipeline 115, so as to prevent suction earth materials and
Obstruction at the bottom end of gravel pipeline 115.Depending on existing soil regime, this pressurization may not be it is necessary,
, in which case it is possible to need not this can pressurized canister 111.
Fig. 7 is the schematic side elevation of gravel feeder system, and it shows the third embodiment of the present invention.According to this implementation
The system of example is actually the reduction procedure of first embodiment.Compared with first embodiment, in this 3rd embodiment, can save
Omit elements below：Separate hopper 107, this separation hopper 107 inside all elements, return duct 109, can pressurized canister
111st, the first valve 113, the second valve 401, compressor 117 and pressure pipeline 119.Therefore feed pipe 105 is directly connected to gravel
On pipeline 115.In other words, in the third embodiment, gravel feeder system eliminates any between reservoir 101 and soil
Tank or hopper.Remaining element is the same, and they can run with the identical mode in embodiment before.The 3rd
In embodiment, make water and gravel separated from one another in the absence of particular step.When gravel is fed into soil, excessive water will be from
In the space that the distal end of gravel pipeline 115 is advanced between soil on the one hand and two pipelines 114 and 115 on the other hand
Surface.
Illustrative methods according to 3rd embodiment are described briefly referring to the flow chart of Fig. 7 and Fig. 8 below.In step
In rapid 801, liquid is fed through feed pipe 105 and enters in gravel pipeline 115 from reservoir 101.Once liquid is (such as
Water) run in feed pipe, then in step 803, gravel is fed through feed pipe and enters gravel pipe from reservoir 101
In road 115.Here, liquid again acts as transfer medium, to shift gravel.
In step 805, it is determined whether the gravel of the amount of needs is have sent to a specific gravel post.If answer is willing
Fixed, then technique continues in step 807, wherein, motor 103 is closed, to stop the feeding of gravel.However, if it is determined that not having
Have and send enough gravels, then more gravels are fed in step 803.After step 807, pump is closed in step 809
106, and technique terminates.Can move to another position and start again at work by the way that pipeline 114 and gravel pipeline 115 will be followed
Skill sets up more gravel posts.
In the example being illustrated above, gravel transferring device includes feed pipe 105 and gravel pipeline 115, what is shown
In example, they are two single pipelines.But, gravel transferring device is alternatively single pipeline.Implement first and second
In example, gravel transferring device is interpreted also to include other elements in addition to feed pipe 105 and gravel pipeline 115, such as
Separate hopper 107 and be also possible that can pressurized canister 111 etc..
Although in the accompanying drawings with it is described above in be illustrated in detail in and describe the present invention, it is such to show and describe
Regard as it is illustrative or exemplary and not restrictive, the invention is not restricted to disclosed embodiment.Other realities are understood
Apply example and modification, and when based on to accompanying drawing, the research of open and appended claims and when performing claimed invention, this
Art personnel can realize other embodiments and modification.For example, instead of having inclined screen in hopper 107 is separated, can
Capable is to cancel these sieves and only net is placed on before liquid outlet, to stop that any gravel enters return duct 109.And,
Triple components (including three separation hoppers 107 and three can pressurized canister 111), quadruple component (including four Hes of separation hopper 107
