In addition, the outlet opening 2a of the carrier pipe 2 that is connected with the bottom of agitator tank 4 is formed by elastomer rubber.Outlet opening 2a is arranged to the formation of throttling, by the variable mouthful size that melts of elastic force of self.That is, the formation of formation is, the amount of concrete in agitator tank 4 after a little while, because of concrete from heavy and light, the outlet opening 2a of carrier pipe 2 is closed condition, and when leaving a large amount of concrete in agitator tank 4, because of concrete deadweight increases the weight of to open outlet opening 2a.Like this, in agitator tank 4, be full of concrete, can further improve stirring efficiency.
Below, the agitator tank 4 of detailed description ready-mixed concrete.Fig. 4 is the oblique view of monomer of agitator tank 4 of the concrete casting filling device of expression present embodiment.By a plurality of monomers based on vertical connection, add up to 3 and alternately connect two kinds of monomer 4a, 4b, constitute agitator tank 4.For convenience of description, Fig. 4 represents to connect the state of these two kinds of monomer 4a, 4b.
Below, describe with regard to the concrete formation of each monomer.Initial a kind of monomer (first monomer) 4a has foursquare both ends, and the flange 41 that interconnects this monomer is set at these both ends.In addition, this monomer 4a has two distortion paths 42,43 of equidirectional configuration arranged side by side.In the end of this monomer 4a, about form lengthwise opening ground and next door 44 be set in central authorities.
The left and right sides opening of this lengthwise is each inlet portion 42a, 43a of two distortion paths 42,43.In the opposing party's of monomer 4a end, form the opening ground of growing crosswise up and down and next door 45 is set in central authorities.This upper and lower opening of growing crosswise is respectively come in and go out oral area 42b, the 43b of two distortion paths 42,43.That is, change the next door 44 of entrance side end of 90 degree directions ground configuration monomer 4a and the next door 45 of outlet side end mutually.
So, form the assortment image of two inlet portion 42a, 43a of distortion path 42,43 about OBL opening abreast, in addition, OBL opening forms the assortment image of two 42b of export department, 43b of distortion path 42,43 up and down abreast.As the concrete shape of being out of shape path 42,43 is described, each cross sectional shape that is out of shape path 42,43 is to change continuously to the 42b of export department, 43b from inlet portion 42a, 43a.
About the mode of this variation, each sectional area that is out of shape path 42,43 optional position from inlet portion 42a, 43a to the 42b of export department, 43b is all identical, and just cross sectional shape changes continuously.Promptly, inlet portion 42a, 43a are towards the long rectangle of directions X, and at the pars intermedia of inlet portion 42a, 43a and the 42b of export department, 43b, its cross sectional shape is a square, at the 42b of export department, 43b is the Y direction long rectangle vertical with directions X, so forms cross sectional shape.In addition, the length of distortion path 42,43 is identical.
Therefore, by the concrete of each distortion path 42,43, its cross sectional shape changes to square gradually from the long rectangle of directions X, changes to the long rectangle of Y direction gradually then.In this monomer 4a, as shown in Figure 4, utilize distortion path 42 to be communicated with inlet portion 42a that is positioned at the left side and the 42b of export department that is positioned at the top, utilize distortion path 43 to be communicated with inlet portion 43a that is positioned at the right side and the 43b of export department that is positioned at the below.
In addition, the monomer 4a with above-mentioned is identical basically for another kind of monomer (second monomer) 4b, but in monomer 4b, as shown in Figure 4, utilize distortion path 46 to be communicated with inlet portion 46a that is positioned at the left side and the 46b of export department that is positioned at the below, utilize distortion path 47 to be communicated with inlet portion 47a that is positioned at the right side and the 47b of export department that is positioned at the top.That is, monomer 4b and each inlet portion of each distortion path and the mode of communicating of each export department are different from monomer 4a.
Fig. 4 represents alternately to connect the mode of two kinds of monomer 4a, 4b like this.That is, above-mentioned two kinds of monomer 4a, 4b are the outlet side ends that the entrance side end of the opposing party's monomer 4b are overlapped on a side monomer 4a, and flange 40 is driving fit mutually to each other, connects with bolt.
Therefore, connecting portion at two kinds of monomer 4a, 4b, the inlet portion 46a's of the distortion path 46 among the 42b of export department of the distortion path 42 among one side's the monomer 4a and the opposing party's the monomer 4b is one semi-connected, simultaneously semi-connected with in abutting connection with the inlet portion 47a of the distortion path 47 of this distortion path 46; In addition, the inlet portion 46a's of the distortion path 46 among the 43b of export department of the distortion path 43 among a side the monomer 4a and the opposing party's the monomer 4b is one semi-connected, simultaneously semi-connected with in abutting connection with the inlet portion 47a of the distortion path 47 of this distortion path 46.
Therefore, by among a side the monomer 4a respectively be out of shape path 42,43 concrete each half, in the path of distortion separately 46,47 of the monomer 4b by entering the opposing party, form the interflow in fact.But,, seem to be cut apart by each half ground at the connecting portion of two monomer 4a, 4b for concrete by a distortion path.
So at the connecting portion of these two monomer 4a, 4b, that is, each export department that is out of shape path separately and each inlet portion that outlet side end and entrance side end form constitute concrete interflow partition means.If alternately connect such monomer 4a, 4b, just constitute concrete interflow partition means at connecting portion separately.
Below, concrete the flowing in such concrete casting filling device is described.
Insert the mouth of pipe of the cantilever of concrete mixer 6 shown in Figure 2, in carrier pipe 2, squeeze into the concrete that stirs by above-mentioned truck-transit mixer 5.At this moment, because the crawler crane 1 suspention carrier pipe 2 of freedom of movement preferably by operation crawler crane 1, moves on to concrete mixer 6 with carrier pipe 2 and can squeeze into concrete position.For example, when in carrier pipe 2, squeezing into concrete, carrier pipe 2 hung is raised to the top from concrete mixer 6, from carrier pipe when the construction operation face is squeezed into concrete, carrier pipe 2 is moved (with reference to Fig. 1) downwards.Like this, by operation crawler crane 1, also easily the concrete in the carrier pipe 2 is moved on to concrete pouring position.
In addition, above-mentioned carrier pipe 2 is connected tens meters long, the concrete that drops into this carrier pipe 2 falls by deadweight along carrier pipe 2.This concrete is in the way that falls along carrier pipe 2, by the buffer 3 that is connected with carrier pipe.Concrete reduces concrete falling speed by the sheet material 32 in the buffer device for collision 3, flows to agitator tank 4.When agitator tank 4 flows down, two inlet portion 42a, the 43as of concrete from the initial monomer 4a of agitator tank 4 enter and respectively are out of shape path 42,43, then, and along continuing to flow down, stir by deadweight in the agitator tank 4.
Below, illustrate along the concrete whipping process that flows down in the agitator tank 4 with reference to the Fig. 5 that represents engineering drawing.In addition, this project figure represents that with illustraton of model with monomer 4a be the top with regard to the zone of the entrance side end of each monomer 4a, 4b, pars intermedia, outlet side end, continuously the concrete variation pattern when 4a, 4b.
As can be seen from Figure 5, the entrance side end of concrete in the monomer 4a in the 1st stage of dropping into carrier pipe 2 enters two distortion paths 42,43, the result, and it flows and is divided into two of A, B.This concrete cross sectional shape of cutting apart all is the long rectangle of directions X.
Then, at the pars intermedia of phase I, the stream shape body section shape of concrete A, B all becomes square, in addition, in the outlet side end in the 1st stage, all is varied to the long rectangle of Y direction that differs 90 degree with the longitudinal direction X of entrance side.Therefore, the shape body section change of shape that respectively flows of concrete A, B is the rectangle that the long rectangle → square of directions X → the Y direction is long.
In the process of this variation, each internal face that is out of shape path 42,43 bears continuous compression (compressive force and shearing force).As a result, in concrete flow-like self, produce particularly about the cross section radially continuously to flow phenomenon, carry out primary stirring action thus.
Below, the next door 48 of the entrance side end of the monomer 4b of second stage is owing to vertically intersect with the next door 45 of the outlet side end of the monomer 4a of phase I, the concrete A, the B that flow out from the outlet end of the monomer 4a of phase I, as shown in Figure 5, separately by about cut apart, be divided into A/B and A/B.
Then, at each distortion path 46,47, flowing concrete A/B.That is, in the entrance side end of the monomer 4b of second stage, the part of concrete A, B is interflow in each distortion path 46,47 respectively, and the concrete stream shape body section shape in each path all is the rectangle that directions X is grown.
Then, at the pars intermedia of second stage, the stream shape body section shape integral body of concrete A/B becomes square shape, and, in the outlet side end, all be varied to the long rectangle of Y direction.In this second stage, the shape body section shape that respectively flows of concrete A/B also is changed to the rectangle that the long rectangle → square of directions X → the Y direction is long.
In addition, in the process of this variation, each internal face that is out of shape path 46,47 bears continuous compression (compressive force and shearing force).As a result, in concrete stream shape body self, produce particularly about the cross section radially continuously to flow phenomenon, carry out secondary stirring action thus.
About the phase III, illustrate especially, in the entrance side end of phase III,, shown in the imaginary line X1 that adds, cut apart about quilt the final concrete in the outlet side end of second stage shown in Figure 5, collaborate with the A/B/A/B form.Below, stir in the same manner with phase I, second stage.By such operation, concrete is stirred once more.
Like this, by concrete being applied compressive force and shearing force, with this active force calendering, overlapping gathering materials, once more this being gathered materials applies compressive force and shearing force, by compression, overlapping repeatedly, stirs again.
In the present embodiment, throttling is set by outlet opening at the carrier pipe 2 that is disposed at the lower end, and based on the pressurization of the concrete weight that flows down along carrier pipe 2 etc., the concrete in the agitator tank 4 flow down under pressurized state.As a result, can apply above-mentioned compressive force and shearing force effectively to concrete.
Relative therewith,,, so be difficult to concrete is applied stirring required compressive force and shearing force only along the stirring means of agitator tank 4 whereabouts as employing owing to the hypothesis concrete flows down in the state lower edge agitator tank 4 that is not full of sometimes.
In addition, the concrete flow of Jiao Baning arrives the carrier pipe 2 that is connected with the lower end of agitator tank 4 once more, and discharges from the outlet opening of this carrier pipe 2, is poured onto the scene as the destination.The concrete of pouring gathers materials and does not separate owing to be just to stir, and is fully stirred, and is the concrete of mobile homogeneous.
Therefore, the terminal operation at concrete casting scene is also easy, can improve operation thus.In addition, as the concrete casting filling device of present embodiment, when concrete descent path reaches tens meters,,, also be very effective to improving concrete intensity owing to can after stirring once more, water immediately even in the way, whereabouts, produce the segregation phenomenon of gathering materials.
In addition, in the time of falling when concrete casting,, can be reduced in the concrete falling speed of outlet opening 2a of carrier pipe 2 owing to below carrier pipe 2, be connected with buffer 3 and agitator tank 4 by deadweight.As a result, can prevent to splash from the concrete that carrier pipe 2 is discharged.
Usually, the state owing to being in carrier pipe 2 near free-falling even the lower end of carrier pipe 2 near concrete casting face, does not in fact change falling speed yet, can not obtain splashing preventing effect so yet.On the contrary,,, the concrete speed of the concrete casting face of dropping to can be effectively reduced, the effect of splashing can be prevented owing to below carrier pipe 2, be connected with buffer 3 and agitator tank 4 as adopting present embodiment.
In addition, by connecting buffer 3,, can improve the durability of agitator tank 4 because concrete can reduce along the bump that flows to agitator tank 4 under the state of the concrete speed of carrier pipe 2 free-fallings, can protect agitator tank 4 to avoid concrete when falling.
In addition, for example,, also buffer 3 can be set, increase the number of agitator tank 4, bear the impact of concrete whereabouts with the agitator tank 4 of topmost in order to protect agitator tank 4.But buffer 3 is more simple in structure than agitator tank 4, can reduce cost.Therefore, by with buffer 3 protection agitator tanks 4, also can improve economy.
Concrete casting operation when in addition, the concrete casting filling device of above-mentioned formation can also be used to implement the shield driving method.When in such protection construction method, adopting above-mentioned concrete casting filling device, for example, set carrier pipe 2 to the bottom from the top of vertical shaft, this carrier pipe 2 bottom near connection buffer 3 and agitator tank 4.Near the top of vertical shaft, set truck-transit mixer 5, below the concrete outlet opening 2a bottom that is arranged on carrier pipe, configuration truck-transit mixer (not shown).
Below, illustrate that the concrete of concrete casting filling device when implementing the shield driving method flowed.At first, will put into the carrier pipe 2 from truck-transit mixer 5 with the concrete that above-mentioned truck-transit mixer 5 stirs.The concrete of putting in the carrier pipe 2 falls by deadweight along carrier pipe 2.This concrete by being arranged near the bottom buffer 3 and the agitator tank 4 of carrier pipe 2, is stirred in the way that falls along carrier pipe 2 once more.Then, the concrete of discharging from the outlet opening 2a of carrier pipe 2 lower ends is put into truck-transit mixer (not shown).This concrete is transported in the tunnel by truck-transit mixer, transports to the position of regulation.
