Aşınmaya dayanıklı boru beton pompası kamyon taşıma için tasarım

Concrete conveying pump car wear-resistant pipe design concrete pipe, meli
according to the engineering and construction site characteristics, beton
pouring scheme for piping. It is advisable to shorten the pipe length and use
less elbow and hose.

taşıma borusunun döşenmesi güvenli bir yapı sağlamalıdır, easy to clean
the pipe, sorun giderme ve demontaj bakım. Aynı boru hattında, the
concrete conveying pipe of the same pipe diameter should be used, and the new
pipe should be arranged in a larger pressure place at the same time when new and
1st pipe sections are used, and the pipeline should be arranged horizontally and
vertically. The layout of the pipe should be drawn, listing all kinds of pipe
bağlantı parçaları, pipe connecting ring, elbow and other specifications and quantities,
and make a list of spare parts. The concrete conveying pipe should be selected
according to the maximum size of coarse aggregate, the type of concrete pump,
the conveying distance of concrete output and the difficulty of conveying. The
conveying pipe shall have the strength suitable for the pumping condition. You
should use a pipe segment with no cracks, no bump damage, and no bends. The
joint of the conveying pipe should be tight, strong enough, and can be quickly
installed and disassembled.

When the minimum pipe diameter of the conveying pipe is loomm, the maximum size
of coarse aggregate can not exceed 25mm, and the minimum diameter is 125mm, the
maximum size can not exceed 40mm. Vertical pipe, the horizontal pipe length
should not be less than one-fourth of the length of the vertical tube, ve
should not be less than 15m, or comply with the provisions of the product
belirtimi.

A cut-off valve shall be set at the root of the conveying pipe at the 3~6m of
the Y-shaped pipe discharging port of the concrete pump to prevent the concrete
mixing from flowing back. When pumping construction of underground structure,
the horizontal pipe axis should be perpendicular to the Y-shaped pipe
discharging port axis.

When tilting the pipe downward, the upper end of the inclined tube shall be
provided with a discharge valve, and when the height difference is greater than
20m, the horizontal tube of 5 times times the height difference length should be
set up at the lower end of the oblique pipe; The fixed concrete conveying pipe
shall not be directly supported in the steel bar, formwork and embedded parts,
the horizontal tube should be at a certain distance with a stent, cushion,
hanging fixture, vb. to facilitate the removal of plugging, installation and
cleaning pipelines, vertical pipe should be fixed with embedded parts of the
wall and pillar or floor of the roof left hole place. On walls and columns, each
pipe shall not be less than 1 fixed points and shall be fixed at each floor of
the floor reservation. The bent pipe at the lower end of the vertical tube
should not be used as the support point of the upper pipe. It is advisable to
set the steel support to bear the vertical pipe weight. When the vertical pipe
is fixed on the scaffold, the scaffold can be strengthened according to the
need.

The pipe joint clamp place shall not leak slurry. The hot season construction,
should use the wet cover cloth, the warm grass bag and so on to cover the
concrete conveying pipe, avoids the sunlight illumination. Cold season
inşaat, it is advisable to use thermal insulation material to cover}
Kun-soil conveying pipe, to prevent the concrete in the tube freezing, and to
ensure the temperature of the concrete into the mold.

(Pompa tüpü) When the horizontal conveying distance exceeds 200m, vertical
transmission distance of more than 40m, conveying pipe vertical downward or
oblique pipe front layout horizontal tube,} Kun-ning soil mixing unit cement
dosage is lower than 300kg/m3, must be reasonable choice of piping method and
pumping process, it is advisable to use a large diameter concrete pipe and long
conical tube, Use less elbow and hose.

When the conveying height exceeds the maximum conveying distance of the concrete
pompa, it can be pumped by the relay pump (subsequent pump). Ek olarak,
according to the engineering structure characteristics, construction technology,
cloth requirements and piping conditions, vb., select cloth equipment.
According to the structure plane size, piping situation and the length of the
distribution bar, the layout of the cloth equipment, and it should be able to
cover the entire structure plane, and can be uniform, rapid cloth.
The cloth equipment should be installed firmly and stably.
