detailed description

Below in conjunction with accompanying drawing, describe the best implementation mode of the present invention through preferred embodiment, the specific implementation mode here is to illustrate the present invention in detail, and should not be interpreted as the limitation of the present invention, without departing from the spirit and essence of the present invention Various changes and modifications can be made within the scope of the present invention, and these should be included in the protection scope of the present invention.

Example 1

Referring to Figures 1-3, the present invention provides a vertical pipe-making equipment. For example, the vertical pipe-making equipment is characterized in that it includes: an outer mold, the bottom of which is provided with a bottom backing plate, and the upper part is provided with an opening; A first space; and a core mold, which is arranged in the center of the first space; wherein, the outer mold, the middle spacer and the core mold are vertically arranged.

Preferably, the device may further include an external mold vibrator, which is detachably arranged on the outer wall of the external mold, wherein the raw material slurry is poured in from the upper opening, and the external mold vibrator vibrates at the same time, so that the slurry is smoothly injected into the bottom And gradually filling the plurality of first spaces.

Preferably, the device further includes a grouting device and a grout inlet provided at the bottom pad or the lower end of the outer mold, and the grouting device communicates with the first space through the grout inlet.

Preferably, the number of the plurality of first spaces is more than two, among which four, six, or nine are optimal.

Preferably, there is provided a process for preparing concrete pipes using the above-mentioned vertical pipe-making equipment, which is characterized in that: using grouting equipment to pump concrete slurry from the slurry inlet into the plurality of first spaces until it is Fill to full and then set to form concrete pipe. Through such arrangement, the concrete slurry enters the first space from the lower part and discharges air, and the concrete slurry is filled more densely under the action of gravity, and the quality of the finished product is better.

Preferably, there is also provided a process for preparing concrete pipes using the above-mentioned vertical pipe-making equipment, which is characterized in that: the raw material slurry is poured from the upper opening, and the external mold vibrator vibrates at the same time, so that the slurry is smoothly injected into the bottom and gradually The plurality of first spaces are fully filled, and then solidified to form concrete pipes.
