Specifically, the concrete column can be divided into three pouring modes according to the structural requirements of the concrete column:

the first embodiment is as follows: referring to fig. 2 and 3, when the length of the concrete column is too high, layered casting may be used to improve the quality of the compressed casting, and at this time, a whole layer of mold 300 is set up each time, and after the compressed casting is completed and maintained, a second layer of mold 300 is set up. The whole concrete column can be poured by reciprocating in this way.

Step 1: the ground beam 100 is laid on an open field, and then front and side press plates are prepared according to the size of the concrete column. The front pressing plate and the side pressing plate are respectively aligned with the connecting holes formed in the ground beam 100 and then fixed by bolts. Then the front pressing plate and the side pressing plate are fixed by bolts. When the next layer is erected, the pressing plates on the upper layer are fixed correspondingly to the pressing plates on the corresponding positions of the lower layer by bolts, and then the pressing plates on the same layer are fixed.

Step 2: the connecting screw 610 is fixed to a stiffener of the side press plate by a nut (the stiffener is not only advantageous for improving the bearing capacity of the mold 300, but also convenient for connecting with the upper pressurizing means 400). And then fixing an I-beam on the two box beams 620 by using a through hole screw, mounting nuts at the upper ends of the screws, penetrating the box beams 620 through the connecting screw 610 and placing the box beams on the nuts, and mounting a nut on the upper part of the connecting screw 610 to fix the box beams 620. After this step is completed, the box girder 620 and the i-beam need to be leveled in all directions.

The sliding rail 210 is connected to the suspension beam 200 by bolts screwed into prefabricated internal threads. The upper part of the jack 420 is connected with the sliding block 410 by bolts (the sliding block 410 can be directly pushed into the sliding track 210), the lower part is connected with the pressure head 430 by bolts, and the middle part is connected with the high-pressure oil pump by an oil inlet and an oil outlet.

And step 3: before concrete is poured, in order to facilitate demolding, the mold 300 is subjected to oil brushing treatment. And then the connecting ribs 500 are placed, concrete is poured into the mold 300, and the concrete is vibrated and leveled (so as to ensure uniform stress during compression) until the concrete is filled to the designed height. The lifting jack 420 is pushed into the sliding rail 210 through the upper slider 410, and the pressurizing means 400 is adjusted to a proper height to allow the pressing head 430 to contact the concrete, so that the lifting jack 420 can be extended by a maximum distance.

The high pressure oil pump is turned on and operated to extend the jack 420 to compress the concrete. After the load reaches the design pressure, the holding pressure can be selected for a period of time or the pressure can be released immediately as required.

And 4, step 4: after the pressurization is completed, the lower ram 430 is removed from the jack 420, and then the jack 420 is pushed out of the slide rail 210, and the upper slider 410 is removed from the jack 420. The nuts on the top of the box girder 620 are removed and the box girder 620 and the devices attached to the box girder 620 are lifted out of the screws. In turn, the suspension beam 200 is removed from the sliding rail 210 and the suspension beam 200 is removed from the box girder 620. At this time, the screw may also be removed, and all the pressurizing devices 400 are oiled and maintained together.

And 5: after concrete curing is completed, the bolts between the front pressing plate and the side pressing plate and the bolts between the side pressing plate and the lower pressing plate (the ground beam 100) are firstly removed, and the side pressing plate is removed.

The lower part is also connected with the pressure head 430 by bolts, and the middle part is connected with the high-pressure oil pump through an oil inlet and an oil outlet.

And step 3: before concrete is poured, in order to facilitate demolding, the mold 300 is subjected to oil brushing treatment. And then the connecting ribs 500 are placed, the concrete is poured into the mold 300, and the concrete is vibrated and leveled until the concrete is filled to the designed height. The lifting jack 420 is pushed into the sliding rail 210 through the upper slider 410, and the pressurizing means 400 is adjusted to a proper height to allow the pressing head 430 to contact the concrete, so that the lifting jack 420 can be extended by a maximum distance.

The high pressure oil pump is turned on and operated to extend the jack 420 to compress the concrete. After the load reaches the design pressure, the holding pressure can be selected for a period of time or the pressure can be released immediately as required. After the casting of the section is completed, the jack 420 is slid to the next compression casting section, and the step is repeated to perform casting.

The nuts on the top of the box girder 620 are removed and the box girder 620 and the devices attached to the box girder 620 are lifted out of the screws. In turn, the suspension beam 200 is removed from the sliding rail 210 and the suspension beam 200 is removed from the box girder 620. At this time, the screw may also be removed, and all the pressurizing devices 400 are oiled and maintained together.

And 5: after the concrete curing is completed, the bolts of the front pressing plate and the side pressing plate, the bolts of the side pressing plate and the ground beam 100 (lower pressing plate) and the bolts between the side pressing plate and the side pressing plate are removed. And then the bolts between the front pressing plate and the ground beam 100 or the bolts between the lower pressing plate are removed, and the bolts between the front pressing plate and the front pressing plate are removed.

The length and the width of the concrete column are approximately equal, and the length direction can be solved through the sectional pouring. In the width direction, there are two construction methods. Firstly, the length of the pressure head 430 in the width direction of the coagulation column is increased; and secondly, after one-time sectional pouring is finished, moving the mold 300 to the next sectional pouring section, repeating the steps, finishing pouring, and completely oiling and maintaining after the mold 300 is disassembled.

Example three: referring to fig. 6, in general, a compression casting, that is, a mold 300 for setting up the whole pillar at one time, may be adopted, and after the compression casting and the curing are completed, the whole is removed.

Step 1: the ground beam 100 is laid on an open field, and then front and side press plates are prepared according to the size of the concrete column. The front pressing plate and the side pressing plate are respectively aligned with the connecting holes formed in the ground beam 100 and then fixed by bolts. If the volume is larger, the front (side) pressing plate on the same surface needs to be fixed. Then the front pressing plate and the side pressing plate are fixed by bolts. When the next layer is erected, the pressing plates on the upper layer are fixed correspondingly to the pressing plates on the corresponding positions of the lower layer by bolts, and then the pressing plates on the same layer are fixed.

Step 2: the connecting screw 610 is fixed to a stiffener of the side press plate by a nut (the stiffener is not only advantageous for improving the bearing capacity of the mold 300, but also convenient for connecting with the upper pressurizing means 400). And then fixing an I-beam on the two box beams 620 by using a through hole screw, mounting nuts at the upper ends of the screws, penetrating the box beams 620 through the connecting screw 610 and placing the box beams on the nuts, and mounting a nut on the upper part of the connecting screw 610 to fix the box beams 620. After this step is completed, the box girder 620 and the i-beam need to be leveled in all directions.

The lower part is also connected with the pressure head 430 by bolts, and the middle part is connected with the high-pressure oil pump through an oil inlet and an oil outlet.

And step 3: before concrete is poured, in order to facilitate demolding, the mold 300 is subjected to oil brushing treatment. And then the connecting ribs 500 are placed, the concrete is poured into the mold 300, and the concrete is vibrated and leveled until the concrete is filled to the designed height. The lifting jack 420 is pushed into the sliding rail 210 through the upper slider 410, and the pressurizing means 400 is adjusted to a proper height to allow the pressing head 430 to contact the concrete, so that the lifting jack 420 can be extended by a maximum distance.

After the load reaches the design pressure, the holding pressure can be selected for a period of time or the pressure can be released immediately as required. After the pouring of the section is finished, if sectional pouring or layered pouring requirements exist, the jack 420 is slid to the next compression pouring section, and the step is repeated for pouring.
