The machine 220 that illustrates also comprises having the concrete feed appliance 330 of including mouth 332 and outlet opening 336 in.Outlet opening 336 comprises the forward direction outlet 338 in the face of the axial translation direction, and comprises that the back is to outlet 340.
The machine 220 that illustrates comprises sliding shuttering 370, and sliding block 370 is suitable for receiving the concrete 334 of discharging from outlet opening 336 to outlet 340 via the back.Along with machine 220 continues axial translation along plate 110, concrete 334 has formed not solidified second concrete slab 120.
In the drawings, lid 350 covers forward direction outlet 338.In illustrative embodiments more of the present invention, lid 350 may be operably coupled to height adjustment mechanism, and this height adjustment mechanism is operable as with respect to the upper surface 310 of first concrete slab 110 and the height of adjustable cap 350.This height adjustment mechanism is schematically illustrated as controller 360.Alternatively, controller 360 comprises electronic building brick and/or the hydraulic package and/or the mechanical component of the removable cover 350 in response to input signal.Alternatively, manually (for example, via action bars or button) or automatically (for example, via unshowned sensor) this input signal is provided.
Fig. 3 B schematically shows insert 221 in more detail.According to the illustrative embodiments that illustrates, lid 350 comprises the retaining element 350 that supports displaceable element 351.Displaceable element 351 for example raises alternatively with respect to the upper surface 310 of first plate in response to the control signal of coming self-controller 360 or reduces (Fig. 3 A).In the illustrative embodiments that illustrates, retaining element 350 extends to the level height of the upper surface 311 of second plate 120 downwards.According to various illustrative embodiments of the present invention, displaceable element 351 can have different movings range with respect to the lower edge of retaining element 350 and/or the upper surface 310 of first plate.Exemplary scope has below been described.
Alternatively, machine 220 comprises that the height (h) that is suitable for the concrete in the concrete feed appliance 334 334 remains on the feed appliance adjuster within the predetermined limits.This feed appliance adjuster depends on the control of the flowing velocity of the adjusting of height of 350 pairs of controllers lid 350 and/or concrete 394 that the opening 392 from concrete pump 390 is entered alternatively.Optionally, manually (for example, via action bars or button) or automatically (for example, in response to output signal) operation feed appliance adjuster from the pressure sensor that is installed in 380 places.
Alternatively, machine 220 comprises pressure regulator, and this pressure regulator is suitable for the hydrostatic pressure of the concrete 334 of back in outlet 340 is remained within the predetermined limits.In illustrative embodiments more of the present invention, pressure regulator is by control h and/or cover 350 opening degree and come work.
In illustrative embodiments more of the present invention, the height by the concrete 334 of control in the feed appliance 330 and/or cover 350 opening degree and/or the back to the hydrostatic pressure of outlet 340 reduce upper surface 311 axially and/uneven degree on dimension or the transverse dimensions.
Additional exemplary modification to the sliding shuttering machine
Still with reference to Fig. 3 A, pull flexible sheets 380 in machine 220 back, alternatively or additionally reduce the uneven degree of upper surface 311 by upper surface 311 along second plate 120.In the illustrative embodiments that illustrates, mounting bracket 382 is suitable for pulling flexible sheets 380.Alternatively, conductor spacer 384 remains on support 384 and the position of shell 320 at a distance of desired distance.Alternatively, mounting bracket 384 is provided as the horizontal bar upper surface 311 of second plate 120 (alternatively across).

Example
Now with reference to following example, this example has been explained the present invention with above description in nonrestrictive mode.
Seasonal variety in the prescription
(Israel) carries out test period in Jerusalem, and clearly, seasonal climate change has brought adverse effect for the performance of Appitrack system.In order to offset the adverse effect of seasonal climate change, fill a prescription independent summer and fill a prescription winter for concrete has been developed.
Table 1 has been summed up the relative quantity of the composition of comparing with the typical concrete prescription of applied by hand that is used for summer and winter prescription.
In addition, table 1 illustrates available slump data, tensile strength and compressive strength data.
The average slump that has dropped to 6 centimetres (summers and winter prescription) from 15 centimetres (manual prescription) when result shown in Figure 1 has shown production was not brought adverse effect to compressive strength in the time of 28 days.
This example has shown that with the performance data of collecting at the scene the plasticity of concrete increase helps to reduce bed plate cracking on every side and allows to carry out more quickly the track installation simultaneously.
